Why Your Address Matters to Insurers
Where you live and, specifically, where your car is kept overnight is one of the most significant factors insurers use to calculate risk. Local crime rates, traffic density, accident statistics and the likelihood of vandalism or theft all vary by postcode, and insurers price policies accordingly.
Because of this, moving house is treated as a "material change" to your policy, not a minor administrative update. Insurers require you to declare it as soon as reasonably possible.
When and How to Update Your Address
When to Notify Your Insurer
You should contact your insurer before or as soon as possible after you move, rather than waiting until renewal. Most insurers allow you to update your address online, by phone, or through an app.
What Information You'll Need
- Your new address and postcode
- The date you moved or plan to move
- Where the car will usually be kept overnight (driveway, garage, on-street)
- Your policy number
How an Address Change Affects Your Premium
Moving can increase or decrease your premium depending on the relative risk profile of your new postcode compared to your old one. Moving to an area with higher theft rates or busier roads may increase your premium, while moving somewhere quieter with off-street parking may reduce it.
What Happens If You Don't Update Your Address
Even if you don't intend to claim, driving on an outdated policy where your correct risk profile isn't reflected can be considered a breach of your duty to provide accurate information under the policy terms.
Moving Abroad or Temporarily Relocating
If you are moving outside the UK, or relocating temporarily, speak to your insurer directly, as standard UK car insurance policies are generally designed for vehicles kept and used in the UK. Requirements can vary significantly by insurer and by destination.

Do I have to tell my car insurer if I move house?
Yes. Address is a key rating factor and a material fact you must disclose. Most insurers require notification as soon as reasonably possible after a house move.
Will my car insurance premium change if I move?
It may increase or decrease depending on how your new postcode compares to your old one in terms of risk factors such as theft rates and traffic density.

Does changing address cost anything?
Some insurers charge a mid-term adjustment fee to process changes, in addition to any premium difference resulting from the new risk profile. Check your policy terms.
