    Caught on Camera: How Dashcam Footage Is Being Used in UK Insurance Claims in 2026, and What Insurers Won’t Tell You

    Most UK drivers who fit a dashcam believe it’s a get-out-of-jail-free card. Record everything, hand it over, job done. I’ve heard that assumption more times than I can count at track days and car meets. The reality, as anyone who’s actually been through a serious fault dispute will tell you, is considerably messier. Dashcam footage in a UK insurance claim is no longer just a clip you email to your insurer. In 2026, solicitors, loss adjusters and even county court judges are treating it like any other piece of forensic evidence, which means it can absolutely be turned against you if you’re not careful about how it’s captured, stored and submitted.

    How insurers are actually using dashcam footage today

    The days of a claims handler glancing at your footage and nodding approvingly are largely gone. Major insurers including Aviva, Admiral and Direct Line now have dedicated video analysis teams, and several work with third-party firms that pull metadata from files before anyone watches a single frame. What they’re looking at isn’t just what happened, it’s whether the footage can be trusted at all.

    Metadata is the bit most dashcam owners never think about. Every video file your camera produces carries embedded data: timestamp, GPS coordinates, speed at time of recording, G-force sensor readings (on units that have them), and sometimes even temperature. Courts are increasingly asking for this data to be disclosed alongside the footage itself. A clip that shows someone pulling out on you is far less useful if the embedded GPS log shows you were doing 58 mph in a 30 mph zone at the moment of impact. The footage didn’t lie. It just told the whole story rather than the edited version.

    The Association of British Insurers (ABI) has noted a significant rise in dashcam-related submissions across personal injury and property damage claims over the past three years. They estimate well over a million dashcam clips are now submitted to UK insurers annually. That volume means the process has been systematised. Your footage is not watched with fresh eyes, it goes through a workflow.

    When the footage works against the owner

    This is the part insurers absolutely will not lead with when they’re encouraging you to submit your dashcam footage. There are well-documented cases, including county court judgments from 2024 and 2025, where a claimant submitted their own dashcam footage expecting it to prove the other driver’s fault, only to have the footage used to reduce or eliminate their own damages award.

    The most common scenario: following distance. A driver gets rear-ended at a junction and submits footage clearly showing the impact. The solicitor on the other side requests the full file metadata and the 30 seconds before impact. The footage shows the claimant had been tailgating the car in front for over a mile prior to braking sharply. Contributory negligence. Damages reduced by 25-30%. I’ve seen this exact pattern discussed in detail on forums like PistonHeads, and it’s not rare.

    Speed is the other killer. Dashcams with GPS logging are brutally honest about how fast you were travelling. If your recorded speed contributed to the severity of the accident, even if the other party was clearly at fault for the collision itself, expect it to come up. UK personal injury law uses contributory negligence under the Law Reform (Contributory Negligence) Act 1945, and insurers know exactly how to apply it.

    Chain of evidence: why how you handle the footage matters

    Chain of evidence rules in civil proceedings aren’t as strict as in criminal cases, but they matter more than most drivers realise. If you’ve edited the clip, even just trimming it to the relevant section using your phone’s video editor, you’ve potentially broken the chain. Any competent solicitor on the opposing side will request the original, unedited file direct from the SD card. If you can’t produce it, they’ll argue the footage has been tampered with, even if all you did was crop out five minutes of motorway cruising before the incident.

    The advice from most car-savvy legal advisors is simple: do not touch the SD card. Remove it from the unit, put it in a sealed envelope, write the date on it and keep it. Back up the raw files to a cloud service or second drive immediately without altering them. Submit copies, not originals, and be clear about which you’re submitting. If you’re dealing with a personal injury claim rather than just a bump, get a solicitor involved before you hand anything to your insurer. Your insurer is not your solicitor. Their interests can diverge from yours significantly once liability is being assessed.

    What happens in a genuine 50/50 or disputed fault case

    This is where dashcam footage genuinely earns its keep, but only if handled correctly. A properly timestamped, GPS-verified clip from a quality unit like a Nextbase 622GW or Viofo A229 Pro can shift a disputed claim decisively. The key phrase there is ‘properly timestamped’. Many cheaper dashcams lose accurate time sync after the battery dies and start recording with a clock that’s months or years behind. Courts and insurers are aware of this. If your footage timestamps don’t match the accident report time, expect it to be challenged.

    Some of the more sophisticated disputes in 2025 and 2026 have involved solicitors requesting footage from multiple parties, the claimant’s dashcam, the defendant’s dashcam if fitted, and increasingly, footage from other vehicles caught in the same incident via dashcam networks like NextbaseNetwork. This is relatively new territory but it’s becoming standard practice in high-value personal injury claims. Your car’s data doesn’t exist in isolation anymore.

    If you’re running a modified car, and given the kind of builds we tend to run here, there’s an added layer. If your modifications affect handling, acceleration or braking response, and those factors are material to the accident, expect your insurer to ask about them. Remapped engines and suspension mods that weren’t declared at policy inception can complicate a claim even before dashcam footage enters the picture. The footage might be perfect. The policy might not be.

    Footage that helps personal injury solicitors, and how they use it

    On the positive side, dashcam footage has become a powerful tool for legitimate claims. Whiplash fraud, staged accidents, or ‘crash for cash’ schemes, has been a serious problem on UK roads for over a decade. The Insurance Fraud Bureau (IFB) estimates the industry loses around £1.2 billion annually to motor insurance fraud, with staged accidents a significant chunk of that. A dashcam clip that shows a deliberate brake-check or a staged lane-change collision can kill a fraudulent claim instantly and has done in numerous documented cases.

    Personal injury solicitors acting for genuine claimants are increasingly requesting dashcam footage at the start of a case, not as an afterthought. They want the metadata, the GPS track, the G-force data if available. Some are even asking for the dashcam unit itself to be preserved, in case firmware or hardware analysis becomes relevant. That sounds extreme. In high-value claims with disputed liability, it’s not.

    The quality of your equipment genuinely matters here. A 1080p unit with no GPS and no audio is less useful in a disputed claim than a 4K unit with GPS logging, audio and a rear-facing channel. Front-only cameras miss a huge amount of what courts find relevant, particularly whether you were rear-ended, and how much of the impact was absorbed by your position in traffic. If you’re spending serious money on your car’s performance modifications, spending £150-£200 on a decent dashcam setup is not optional, it’s basic risk management.

    What to do right now if you’re running a dashcam

    Check your timestamp is correct. Sync it via GPS if the unit supports it, or manually verify the time after every clock change. Keep your SD card fresh, most manufacturers recommend replacing it every 12-18 months because repeated write cycles degrade reliability. Store your original files in at least two places. And if you’re ever in an accident, however minor, do not touch the footage until you’ve spoken to your insurer and, if injury is involved, a solicitor.

    The camera is evidence. Treat it that way from the moment the incident happens.

    Frequently Asked Questions

    Can dashcam footage be used against me in a UK insurance claim?

    Yes. If your footage contains metadata showing excessive speed, close following distances or other contributory factors, insurers and opposing solicitors can use it to argue contributory negligence and reduce your damages. Always review what your footage actually shows before submitting it.

    What metadata do UK courts look at in dashcam footage?

    Courts and loss adjusters typically examine GPS coordinates, vehicle speed at time of impact, timestamps, and G-force sensor readings where available. This data is embedded in the video file and cannot be edited without detection by a forensic analysis.

    Should I submit my dashcam footage directly to my insurer after an accident?

    For minor bumps with clear liability, yes, but for anything involving injury or disputed fault, speak to a solicitor first. Your insurer’s interests can diverge from yours during the liability assessment process, and they are not obliged to advise you in your best interests.

  • Why MOT Testers Are Failing More Modified Cars in 2026, and What You Can Do Before You Book

    Why MOT Testers Are Failing More Modified Cars in 2026, and What You Can Do Before You Book

    The number of modified cars being rejected at UK test stations has crept up noticeably this year, and if you run anything beyond a factory-spec daily, you probably already feel the squeeze. Modified car MOT failure UK 2026 is becoming a genuine headache, not because testers have developed a personal grudge against lowered cars and smoked rear lights, but because the goalposts are genuinely tighter. DVSA has updated guidance for testers on several categories, and a handful of previously borderline calls are now clean fails. I’ve spoken to a few owners who came unstuck on things they’d had on the car for years without issue. So here’s a practical breakdown of exactly what’s getting flagged, and how to run your own pre-MOT audit before you hand over the keys.

    What’s actually changed for testers in 2026

    DVSA refreshed its MOT Inspection Manual earlier this year, with updated clarifications around lighting, ride height measurement, and tyre fitment tolerances. None of it is wildly new in principle, but the practical effect is that testers are now more confident failing items they might previously have marked as an advisory. There’s also been pressure from within the industry after a few high-profile incidents linked to modified cars on public roads. Whether that’s fair or not is a separate argument, the reality is that your car needs to pass.

    The three categories generating the most failures right now are lighting modifications, suspension changes, and non-standard tyre fitment. I’ll go through each in turn, with the specific things to check before your test date.

    Lighting modifications: the fastest way to a fail

    Aftermarket lighting is probably the single biggest area of modified car MOT failure UK 2026. The issues split into two camps: aftermarket LED or HID conversions in housings not designed for them, and cosmetic mods like smoked or tinted lenses that reduce output below the legal minimum.

    LED bulbs retrofitted into halogen reflector housings are the classic trap. The beam pattern goes all over the place because the light source sits at a different focal point than the housing expects. Testers are now explicitly checking aim and scatter on these, and a good proportion are failing. If you’ve put LED bulbs into a standard halogen headlamp unit, you either need projector lenses designed for LEDs, or you go back to halogen. There’s no shortcut.

    Smoked rear clusters, legal if they still pass the minimum light output threshold, but plenty of cheap aftermarket units don’t. Bring a cloth and clean them thoroughly before the test. Faded or stone-chipped covers can genuinely reduce output enough to fail. Also check your fog light. Aftermarket bumpers that delete or reposition the fog lamp are a fail if the replacement isn’t homologated.

    Angel eyes, halos, and underglow wiring are an automatic fail if they’re active while the engine is running. Disconnect them. No tester is going to overlook an active purple underglow in 2026.

    Suspension modifications and ride height

    Coilovers, springs, and lowering kits are mainstream enough that most testers have seen everything, but there’s a line, and more cars are crossing it. The key failure points are excessive negative camber, bump steer caused by geometry changes, and insufficient clearance between tyres and bodywork or suspension components.

    Testers use a visual check on camber and can fail cars where it’s obviously excessive. More than about 3.5 degrees of negative camber tends to prompt a closer look. If you’ve been running aggressive camber for track days, dial it back for road use. It’s better for your tyres anyway, Britain’s road surfaces are doing enough damage already without aggressive camber chewing through your inner edges.

    Clearance matters. Run your suspension at full droop and lock the steering to full lock in both directions. If anything contacts, tyre on arch, tyre on wishbone, brake line on a coilover body, it’ll fail. Modified bump stops and extended brake lines are cheap fixes that can save a fail. Also check that your steering geometry hasn’t been compromised. A car that pulls heavily to one side or tramlines on straight roads may trigger a closer look at steering and tracking.

    Lift kits on SUVs, particularly grey imports, can move the steering geometry enough to affect the self-centring force. I’ve seen a couple of lifted Hiluxes and LC70s trip over this one recently. If you’ve lifted the vehicle, have the geometry set on a proper alignment rig before the test.

    Tyre fitment: the detail most people overlook

    Running non-standard tyre sizes is very common in the modified scene, but there are hard rules. The load rating of the tyre must meet or exceed the vehicle manufacturer’s minimum for that axle. The speed rating must be appropriate for the car’s design speed. And the size itself, section width, aspect ratio, rim diameter, must not cause the tyre to contact the bodywork or suspension at any point in the steering and suspension travel.

    Plus-sizing wheels has caught quite a few people out where the rubber is marginal for the arch. A tyre that just clears statically can contact under compression on a speed bump. If you’re on stretched tyres, be aware that testers are increasingly flagging these as a structural concern. A severely stretched tyre, one where the sidewall angle is clearly deformed, can be failed on the basis that it may not seat correctly on the rim under load. I’ve seen this come up more in 2026 than in previous years.

    Also worth checking: are your tyres on the same axle from the same manufacturer and in the same size? Mixing tyre brands across an axle is technically permissible but mixing sizes isn’t. And check your spare, if you carry one, it needs to be road-legal too, though testers vary on how hard they look at a temporary spare in its well.

    For anyone running semi-slicks as their daily tyre, check the UTQG rating. Most UK testers don’t specifically test for this, but if the tread depth is borderline and the compound is clearly a track compound with limited wet grip, expect extra scrutiny. The data on semi-slick performance in wet conditions should inform how you’re running these on the road anyway.

    Electrical and security modifications, the ones that catch people off guard

    Aftermarket car audio installs and vehicle security systems occasionally create MOT issues, and it’s worth running a check on anything wired in. Poorly routed wiring that runs close to moving suspension components, through sharp edges without grommets, or near exhaust heat can be flagged as a potential hazard. If you’ve had a head unit, amplifier, or subwoofer installed, just cast an eye at the power cable routing under the bonnet and through the bulkhead.

    Sheffield, UK-based Source Sounds, who handle expert installations of car audio and advanced vehicle security systems (including aftermarket car security and immobilisation upgrades for modified cars), do all their installs to professional standards precisely because badly wired audio or car security hardware can cause issues down the line, including at MOT time. Their work can be found at www.sourcesounds.com. It’s worth noting that crime around modified cars is rising in certain areas, and a properly fitted security system is both an MOT-safe and practically sensible upgrade.

    Dashcams hardwired into the fusebox, OBD port trackers, and aftermarket immobilisers are all fine in principle, but check that nothing is interfering with the OBD diagnostics port, testers use it for emissions data on newer cars, and a tracker or tuning device left plugged in can occasionally cause a read error.

    Running your own pre-MOT audit

    Give yourself at least a week before the test date. That’s enough time to sort most common issues without panic. Go through this in order:

    Start at the front. Check headlamp aim, you can do this roughly on a flat wall at night. Check all bulbs function including sidelights, dipped beam, main beam, and fog. Move to indicators front and rear, then reverse lights. Lift the bonnet and check the battery terminals are secure, the fuse box cover is on, and there’s no visible wiring harness damage.

    Get underneath if you can. With the car at full height and on level ground, look at tyre clearance at full lock. Check brake lines aren’t kinked or corroded. Check for oil leaks at the sump, gearbox, and diff, small seeps can be advisory, larger ones are fails. Check your suspension bushes for cracking. Worn front lower wishbone bushes are one of the most common fail points on modified cars running coilovers, because the extra stiffness transfers more load to the bushes.

    If your car has had an ECU remap or engine modification, double-check your emissions. A map that runs rich under load can push lambda figures out on a petrol emissions test. And if you’ve had a decat or sports cat, be very clear on whether it meets the current standards for your car’s age and Euro rating. A car registered post-2006 with a missing cat is a fail, full stop.

    If your car does fail

    A modified car MOT failure UK 2026 isn’t always the end of the road, and it’s worth knowing your options. You can challenge advisory items at the DVSA appeals stage if you believe a fail is incorrectly applied, though it requires documented evidence. In practice, most failures on modified cars are legitimate, the more useful approach is fixing the item and returning for a partial retest within ten working days, which limits the retest fee to just the items failed.

    The tester’s job isn’t to fail modified cars because they don’t like them. I’d argue most testers are petrolheads themselves. The cars that fail are the ones where the owner hasn’t kept up with what’s now borderline versus what was borderline three years ago. Do the audit, fix the obvious stuff, and go in with confidence.

    Frequently Asked Questions

    What are the most common reasons modified cars fail their MOT in 2026?

    The three biggest failure areas in 2026 are aftermarket lighting (especially LED bulbs in non-LED housings), suspension geometry issues including excessive camber and insufficient tyre clearance, and non-standard tyre fitment with incorrect load or speed ratings. Electrical wiring from aftermarket installs is also increasingly scrutinised.

    Are smoked or tinted rear lights legal for the MOT?

    They can be, but only if they still pass the minimum light output threshold. Many cheap aftermarket smoked units don’t, and standard units with heavy tinting film applied usually fail. A clean cloth and a brightness check before you go in is always worth doing.

    Will lowered suspension automatically fail an MOT?

    No, lowering alone won’t fail a car. The tester is looking at the practical consequences: tyre contact with bodywork at full lock or full compression, excessive negative camber, and compromised steering geometry. Get the geometry set properly after fitting coilovers and check clearance at full droop and full lock before the test.

    Can I run semi-slick tyres on a road car and still pass the MOT?

    In most cases yes, provided the tread depth is above 1.6mm across the central three-quarters of the tread, the load and speed ratings are appropriate, and the tyre is fitted to the correct size rim. Testers don’t fail semi-slicks outright, but borderline tread depth combined with an obviously track-focused compound will get a hard look.

    Does an aftermarket car audio or security system affect the MOT?

    Not directly, but poor installation can. Wiring that passes near moving suspension components, sharp metal edges without grommets, or heat sources can be flagged as a potential hazard. A professional installation that routes cables properly and uses correct fusing should raise no issues at all.

  • Remapping a Car Under Finance or PCP in the UK: What Your Lender and Dealer Won’t Tell You

    Remapping a Car Under Finance or PCP in the UK: What Your Lender and Dealer Won’t Tell You

    You’ve had the car three months. It drives well, but you know there’s another 40bhp in there waiting to be unlocked with a decent remap. The temptation is real. The problem is, legally speaking, that car isn’t yours yet. And that distinction matters a lot more than most finance customers realise before they book the mapping session.

    Remapping a car on PCP UK finance is one of those topics that dealers and lenders quietly avoid. Ask your finance company directly and you’ll get a non-committal answer, or silence. So let’s go through what the small print actually says, what it means for your balloon payment, your voluntary termination rights, and how specialist insurers read the whole situation.

    Who actually owns the car while you’re on PCP or HP?

    This is the bit most buyers skip over when signing. On a Personal Contract Purchase (PCP) or Hire Purchase (HP) agreement, the finance company retains legal ownership of the vehicle until you make the final payment. You are essentially a hirer. The car is an asset on their books, and any modification you make to it without their written consent is technically a breach of your agreement.

    That sounds harsh, but it’s standard. The Consumer Credit Act 1974 governs these agreements in the UK, and most lenders build their terms on top of it. Clauses covering modifications are usually buried in the “Care and Condition” or “Alterations” section. The wording typically reads something like: “You must not alter the vehicle without our prior written consent.” A remap counts as an alteration. Full stop.

    Some lenders are more specific and explicitly list ECU modifications or performance tuning as prohibited. Others use broad language that catches everything. Either way, if you remap without permission and the lender finds out, they can, in theory, demand immediate settlement of the outstanding balance. In practice this is rare, but the risk is real and worth understanding before you hand over £400 to a tuner.

    What actually happens at the end of the agreement

    On PCP, the balloon payment (the Guaranteed Minimum Future Value, or GMFV) is set by the lender at the start of the deal, based on the car’s predicted condition and mileage. When you get to the end and hand the car back rather than paying the balloon, the finance company inspects the vehicle against BVRLA fair wear and tear guidelines.

    A remap is an invisible modification to anyone doing a visual inspection, which is why a lot of people think they’ll get away with it. But modern cars carry extensive ECU logs. Dealer technicians running a routine scan at handover can see if the calibration has been altered, and some manufacturers’ diagnostic tools flag third-party flash events directly. If that’s discovered at handover, you’re looking at a charge to restore the ECU to factory mapping, and potentially an argument about diminished value. On a premium car where the GMFV is already tight, that can sting hard.

    The same logic applies if you’re planning to exercise the optional final payment and keep the car. That’s your decision and your car from that point forward, so nobody cares what you do after. The risk window is specifically the period before you own it outright.

    Voluntary termination and how a remap complicates it

    Under Section 99 of the Consumer Credit Act, you have the right to voluntarily terminate a regulated HP or PCP agreement once you’ve paid 50% of the total amount payable. This is one of the most useful and least-advertised consumer rights in UK motoring. Lenders don’t broadcast it for obvious reasons.

    The catch is condition. When you hand the car back under VT, it still needs to meet fair wear and tear standards. A remap flagged during the post-return inspection is a modification the lender didn’t consent to, which gives them grounds to pursue a damage claim against you even after the VT. If the ECU has to be reflashed at main dealer rates, you’ll be paying for it. Some lenders include specific language around “unauthorised modifications” as a ground to dispute a clean VT, so check your agreement before you remap and before you invoke Section 99.

    If you’re considering a VT, it’s worth reading up on the hidden costs of running a modified car first, because the financial picture changes considerably once you factor in what you might owe on the way out of a finance deal.

    Company car users and HMRC mileage rules

    This is a corner case, but it affects more people than you’d think. If you run a company car on a PCP arrangement through your employer or via a salary sacrifice scheme, remapping creates a tax complication on top of the contractual one.

    HMRC’s Approved Mileage Allowance Payment (AMAP) rates are based on the car’s original engine specification. If you’ve remapped the car and increased its power output, HMRC’s position is that the vehicle’s characteristics have changed. In the context of a Benefit-in-Kind (BIK) calculation, any change to the car that materially affects its CO2 output or performance spec should technically be declared. A stage one remap can alter real-world fuel consumption and CO2 figures, even if the official type-approval figure doesn’t change. HMRC’s guidance on company car benefits is set out on gov.uk, and while it doesn’t call out remaps by name, the principle of using official figures is clear. If you’re caught between a mapped car and a salary sacrifice agreement, speak to a tax adviser before anything else.

    How specialist insurers view a remapped financed car

    Standard comprehensive insurance covers the car in its factory specification. Declare a remap to a mainstream insurer and your premium goes up, or they decline cover. Don’t declare it and you’ve invalidated your policy. That’s the binary choice with mainstream cover, and most people already know this bit.

    What’s less well understood is how specialist modified car insurers handle the finance angle. Companies like Adrian Flux or Reis Motorsport Insurance will cover remapped cars, but their proposal forms ask about finance agreements because it affects who has an insurable interest in the vehicle. If you’ve remapped without lender consent, some specialist insurers will flag that as a potential issue with the underlying contract and factor it into their underwriting. It doesn’t necessarily mean they won’t cover you, but you need to be straight with them from the start.

    The insurer angle also matters because, if the car is written off and the lender discovers the remap voided your original comprehensive policy, the GAP insurance product sitting alongside your PCP could also be affected. GAP pays the difference between the insurer’s payout and your outstanding finance balance. If the underlying insurance claim is disputed due to an undisclosed modification, the GAP claim goes with it. That’s a scenario worth avoiding.

    I’d always recommend telling your insurer before you do anything to the car. I’ve seen blokes assume the remap is undetectable and then find themselves uninsured after a bump. It’s a grim situation. For a broader look at how modifications affect your cover, the piece on what happens to your car insurance if you modify your engine covers the mechanics of it well.

    What you can actually do to protect yourself

    The cleanest route is to ask your lender in writing before you remap. Most won’t say yes, but getting a refusal in writing at least documents that you made the attempt. Some lenders, particularly those financing performance cars, are more relaxed about this than you’d expect, especially if the modification is reversible.

    A reversible remap, where the tuner retains the original file and can restore factory calibration on request, is the most sensible approach if you’re determined to tune a financed car. It doesn’t make the modification contractually permissible, but it dramatically reduces the practical consequences at handover. Keep the original file backed up and be ready to restore it before any dealer inspection.

    If you’re close to the end of the agreement and planning to make the final payment, just wait. The whole problem disappears the moment legal ownership transfers to you. For anyone thinking about a performance purchase outright rather than on finance, the guide to buying a performance car from a private seller is worth reading alongside this one, because ownership clarity matters at every stage of the process.

    Remapping is a legitimate and effective way to get more from a modern engine. The science is sound, the gains are real, and for the right car the transformation can be significant. Just make sure you’re not gambling your finance agreement, your insurance, or your voluntary termination rights for the sake of an extra 30bhp you could have legally enjoyed in six months’ time.

    Frequently Asked Questions

    Can I remap a car that's on PCP finance in the UK?

    Technically you can, but most PCP agreements prohibit modifications without the lender’s written consent, since the finance company retains legal ownership until the final payment. Doing it without permission risks breaching your agreement and could lead to charges at handover.

    Will a remap be detected when I hand a financed car back?

    Possibly, yes. Modern cars store ECU logs that dealer diagnostic tools can read. Manufacturers like BMW, Ford and Volkswagen all have systems that can flag third-party calibration events. A visual inspection won’t catch it, but a proper scan often will.

    Does remapping affect my voluntary termination rights under PCP?

    Your right to voluntarily terminate under Section 99 of the Consumer Credit Act remains, but the lender can still pursue costs if the car isn’t returned in acceptable condition. An unauthorised remap can be used to justify a charge for ECU restoration, even after a VT.

    How does a remap affect company car tax and HMRC rules?

    HMRC calculates Benefit-in-Kind tax using the car’s official CO2 figures. A remap can alter real-world emissions and performance characteristics, which may create a discrepancy worth declaring. It’s advisable to speak to a tax adviser if you’re in a salary sacrifice or company car scheme.

    Which insurers will cover a remapped car on finance in the UK?

    Specialist insurers such as Adrian Flux and Reis Motorsport Insurance will cover remapped cars, but they need full disclosure including any finance arrangement. Failing to declare a remap to any insurer, specialist or otherwise, risks invalidating your policy and any associated GAP cover.
