Fifteen per cent of motor insurance holders have reduced their cover in the last two years, and 61% have switched provider altogether. For most people, the decision came down to one thing: premium cost. But trimming a policy by dropping endorsements — or adding them without checking the price — can change what you’re protected against more than you realise. A single at-fault claim can wipe out years of no-claims discount and push your premium up by hundreds of pounds. The endorsements you choose, or skip, determine how much of that hit you absorb yourself.

Those figures come from the FCA’s latest market analysis, and they paint a clear picture: drivers are cutting costs, shopping around, and rethinking what cover they actually need. But cutting the wrong endorsement — or keeping one that no longer fits — can cost more than it saves. The Road Traffic Act 1988 sets a legal minimum of third-party cover, but everything beyond that is a choice. And with the range of add-ons available, knowing which ones earn their keep is the difference between paying for protection you’ll use and padding a premium you don’t need.
Here’s what you actually need to know.
A policy endorsement is any change or addition to a standard car insurance policy that alters the terms, cover level, or exclusions. Some are optional add-ons — like breakdown cover or legal protection — while others are adjustments like increasing your voluntary excess or adding a named driver. Each one shifts your premium and your risk.
What I tend to notice is that most drivers focus on the base premium and forget that endorsements can change the total cost by 20% or more in either direction. Worth weighing the line items before you auto-renew.
What endorsements actually cost — and what they save you
Every endorsement has a price tag, but the real question is whether it saves you more than it costs. The table below shows typical annual costs for common endorsements and the scenarios where they pay off.

| Endorsement | Typical annual cost | When it pays off |
|---|---|---|
| No-Claims Bonus Protection | £30 – £60 | One fault claim wipes less of your discount |
| Motor Legal Protection | £15 – £30 | Uninsured driver or contract dispute claim |
| Courtesy Car | £40 – £80 | Your car is off the road after a non-fault claim |
| Breakdown Cover | £40 – £120 | Two or more callouts per year |
| Windscreen Cover | £0 – £25 (excess) | Cracked or chipped windscreen repair needed |
| Higher Voluntary Excess (£250 → £500) | Saves £40 – £80 | You can afford the higher excess if you claim |
The numbers shift depending on your age, vehicle, and location. Drivers aged 18–24 are the most likely to reduce cover — 25% have done so in the last two years — partly because their base premiums are already high and endorsements add proportionally more. For older drivers, especially those over 75, the calculus is different: 7% reduced cover, but proposed compulsory eyesight testing could make medical disclosure endorsements more relevant.
One scenario that catches people out: dropping comprehensive cover to third-party only can sometimes increase your premium. Insurers price third-only policies for a risk pool that tends to have older cars and fewer claims — but if your vehicle profile doesn’t match that pool, the quote can come back higher. Always run the comparison both ways.
Where drivers get endorsements wrong
Buying legal protection you already have
Motor Legal Protection sounds like a no-brainer at £15–£30 a year. But many home insurance policies, packaged bank accounts, and union memberships already include legal expenses cover. Check your existing policies before adding it to your car insurance. If you’re already covered, you’re paying twice for the same protection. The FCA found that only 8% of drivers who struggled with payments arranged support from their provider — a similar pattern of people not checking what they already have.
Dropping courtesy car cover to save £50 — then needing it for three weeks
A courtesy car endorsement typically costs £40–£80 a year. Without it, a non-fault claim that puts your car in the shop for three weeks means hiring a replacement or managing without. At £30–£50 per day for a hire car, three weeks costs £450–£1,050. The endorsement pays for itself after about two days. The 15% of drivers who reduced cover may have saved on premium but took on a much larger potential outlay.
Ignoring the voluntary excess trade-off
Raising your voluntary excess from £250 to £500 can save £40–£80 a year. But if you have a claim, you pay the full excess — compulsory plus voluntary — before the insurer pays out. For drivers with low financial resilience (22% of whom reduced cover, per the FCA), a £500+ excess can be unaffordable at the point of claim. The saving only works if you can actually write that cheque when needed.
Not declaring ADAS or self-driving features
From 2026, the Automated Vehicles Act shifts liability to the manufacturer when a car is in self-driving mode. But insurers need to know what features your car has. Advanced driver-assistance systems (ADAS) like lane-keep assist and adaptive cruise control affect risk profiles. Failing to declare them can invalidate your policy. The same applies to telematics boxes — usage-based insurance policies rely on accurate data, and aggressive driving or frequent manual overrides can increase your premium.
How to choose endorsements that fit your driving and your budget
Start with the legal minimum, then build up
The Road Traffic Act 1988 requires third-party insurance as a minimum. Everything else is optional. List the endorsements you currently have and ask which ones you’ve actually used in the last three years. If you’ve never claimed on legal protection or breakdown cover, consider dropping them — but only if you have a backup (bank account cover, family roadside assistance, or a credit card with breakdown benefit). For tangible protection like a Garmin Dash Cam X310, that’s a one-off purchase that can support fault disputes and potentially lower your premium over time.
Match endorsements to your claim history
If you’ve had a fault claim in the last three years, NCB protection is probably worth more to you than any other endorsement. The maths is straightforward: a 5-year NCB at 60% discount on a £1,200 premium saves £720. Drop to a 3-year NCB at 40% and you save £480 — a £240 loss. Protection costs £30–£60. That’s a 4:1 to 8:1 return in the first year after a claim. If you have a clean record going back five years or more, the risk is lower, but one at-fault claim resets the clock.
Factor in 2026 regulatory changes
Several developments will affect endorsement choices. Self-driving vehicle trials begin in spring 2026, and insurers are expected to require declarations about autonomous feature usage. Low-emission zones are expanding, and non-compliant vehicles may face daily charges — some insurers now offer clean air zone endorsements or mileage-based adjustments. The FCA’s claims handling value measures review, concluding in Q4 2026, may also change how add-ons are priced and presented at renewal. Keep an eye on your renewal letter for new endorsement options related to these changes.
Review endorsements at renewal, not just at purchase
Sixty-one per cent of motor insurance holders switched provider at their most recent renewal, up from 52% in 2022. But switching without reviewing endorsements means you might carry over cover you no longer need — or miss new options your current provider doesn’t offer. When you get your renewal quote, compare it against at least two other providers with the same endorsements. Then strip out any endorsement you haven’t used in three years and see how the price changes. A VYNCS Pro telematics device, for example, can feed driving data to usage-based insurers and potentially unlock lower premiums, but only if you’re on a policy that supports it.

Endorsements are the difference between a policy that fits and one that doesn’t
The 15% of drivers who reduced cover and the 61% who switched are both responding to the same pressure — premiums that feel too high for the value received. But cutting across the board isn’t the same as choosing wisely. An endorsement that costs £40 a year can save £300 after a single claim, while one you never use is just a donation to the insurer. The 2026 regulatory changes — self-driving liability, telematics data, low-emission zones — will add new endorsements to the mix. The habit of reviewing each line item at renewal, rather than accepting the default bundle, is what keeps a policy working for you rather than against you.
