IN10 driving-without-insurance car insurance UK 2026

What is an IN10 endorsement and how does it affect car insurance?

An IN10 is the DVLA endorsement code for using a vehicle uninsured against third-party risks, under Section 143 of the Road Traffic Act 1988. It carries 6 to 8 penalty points, a fixed-penalty £300 fine (or an unlimited fine if the case is heard in magistrates' court), and — in more serious cases — a discretionary disqualification of 6 to 12 months. There is no minimum ban for IN10 alone, unlike a DR10 drink-driving conviction, which carries a mandatory 12-month disqualification.

The endorsement stays on your DVLA driving licence for 4 years from the date of the offence, but UK insurers ask about convictions going back 5 years from the date of conviction on most application forms. That declaration window — not the licence retention period — is what determines how long an IN10 drives up your premium. The six UK brokers listed below all underwrite IN10 risks; average year-1 uplift sits at 35%, well below the doubling that a DR10 typically triggers but materially higher than a single SP30 speeding endorsement.

What an IN10 actually costs you beyond the premium

The headline £300 fixed penalty is the smallest part of the bill. Add the four-year insurance uplift modelled above — roughly £212 in year one and around £550 across the full declaration window for a 35-year-old — and the real cost of an IN10 is closer to £850–£900 before you count any escalations. If the police seized the vehicle under Section 165A of the Road Traffic Act, recovery and storage fees add a further £150 release charge plus around £20 per day storage, and an unrecovered car can be crushed.

Where the case goes to magistrates' court rather than being settled by fixed penalty — common when the offence is contested, repeated, or aggravated — the fine becomes unlimited (typically a multiple of weekly income) and the magistrate can impose a discretionary 6-to-12-month disqualification on top of the 6–8 points. A discretionary ban does not carry the mandatory minimum of a DR10 drink-driving case, but it resets your no-claims position and forces you into the year-1 specialist market on your return.

Two structural factors keep IN10 pricing high even for otherwise-safe drivers. First, the UK still has more than one million uninsured drivers, and the Motor Insurance Bureau (MIB) levy — around £15 built into every honest policy — funds compensation for their victims; insurers price IN10 applicants against that population. Second, claims inflation is squeezing the whole market: UK motor claims hit a record £9.9bn in 2023, repair labour is up roughly 40% and ADAS sensor recalibration can turn a £300 bumper repair into a £1,500 job, so any risk-loaded policy carries that inflation on top of the conviction multiplier.

The practical takeaway: an IN10 is expensive but survivable. Keep the vehicle in a low insurance group (groups 1–5), accept a telematics box if you are under 25, declare the conviction at every renewal for the full five years, and let the uplift decay year on year. Drivers who shop the specialist panel each renewal — rather than auto-renewing with the year-1 underwriter — typically recover to within 12% of baseline by year four, as the acceptance and pricing table above shows.
