Moved house or changed job? Tell your car insurer
Moved house, changed job, modified the car? The changes you must tell your car insurer about — and what staying silent can cost at claim time.
Car insurance quietly assumes your life is frozen at quote time. Real households move, change jobs, add drivers and buy roof boxes — and every one of those facts is part of the contract.
The changes worth a phone call
- Address — including where the car is parked overnight; postcode is a core rating factor.
- Occupation — new job, new title, going self-employed, parental leave.
- How the car is used — social-only policies don’t cover commuting; business use is its own class.
- The car — a replacement obviously, but also modifications: tow bars, remaps, non-standard wheels, even some dashcams and wraps.
- Drivers — someone moving in who’ll drive it; a named driver who’s had points or a claim.
- Mileage — if your declared annual figure has become fiction in either direction.
The fee question, played well
Mid-term updates usually carry an admin fee plus the premium change. Two ways to keep it cheap:
- Batch what you can into renewal — changes made at renewal typically carry no admin fee, and you can re-shop the whole policy with the new facts. See our guide on cancelling auto-renewal.
- Report what you must immediately — anything already true (you have moved) protects today’s claim, not next year’s. The fee is the price of a valid policy.
In short
If a fact on your original quote has changed, the insurer needs to know — now for things already true, at renewal for things optional. A £30 admin fee is annoying; a proportionately reduced write-off payout is a different order of problem.
Frequently asked questions
Which changes actually matter?
The ones on your original quote: address (and where the car sleeps at night), occupation and employer type, annual mileage, usage class (social only vs commuting vs business), named drivers, the car itself, and any modification — from a tow bar to alloys to a remap.
Why does my job title change the price?
Insurers price occupations statistically. The point isn’t to game the wording — describing your work inaccurately to get a cheaper price is misrepresentation, which is exactly what lets an insurer walk away from a claim.
Will I be charged for updating details?
Usually a mid-term adjustment fee (often £25–£50) plus any premium difference — occasionally a refund if the change lowers risk. At renewal the same change is free, so report changes when they happen and time optional ones (like adding a named driver) to the renewal if you can.
What about temporary situations?
Borrowed cars, a week of commuting, a visiting driver — short-term needs are often better served by temporary cover or a phone call to check, rather than silently assuming the policy stretches. Assumptions are what claims handlers unpick.
