Switching Car Insurance? What to Check First

Key things to know

1. You can switch car insurers mid-policy, but cancellation fees, refund methods and admin charges vary, so read your current policy’s cancellation terms first.
2. Get written proof of your no-claims discount before cancelling, and check that the number of years recorded is correct.
3. Under continuous insurance enforcement a registered vehicle must stay insured unless it is declared off the road, so match the new policy’s start date to the old one’s end date.
4. Third party is the legal minimum and does not cover repairs to your own car, so compare cover levels and excesses, not just the headline price.
5. After switching, check your car shows as insured on askMID, the database the police use as evidence that a vehicle is covered.

You can switch car insurance at any point, not only at renewal. The mechanics are simple: buy the new policy, cancel the old one, and make sure the dates line up. Where drivers come unstuck is in the details around the edges, such as losing proof of a no-claims discount, paying a fee they had not budgeted for, or leaving the car uninsured for a single afternoon. This checklist takes you through each of those points before you commit to anything.

Check Your Renewal Date and Notice Period

Two dates matter before anything else: the day your current policy ends and the day the new one would start.

• Find the exact end date. It is on your policy schedule or renewal invitation, and it is not always the date you expect, so check the document rather than working backwards from when you bought the car.
• Check whether the policy renews automatically. Many policies roll over unless you tell the insurer otherwise, so if you do nothing, the cover may continue on the insurer’s new terms and at a new price.
• Note any notice period. Insurers set their own rules on how far in advance changes or cancellations must be requested, so read your documents instead of assuming you can act on the day.
• Decide whether to switch at renewal or mid-policy. Renewal is often the cleaner option because nothing needs cancelling and the renewal notice gives you a current price to compare against. Our guide to what the FCA pricing rules mean for you explains how renewal pricing is regulated.
• Arrange the new policy in advance if you can. You can usually buy a new policy and set its start date ahead of time, which makes the handover much easier to control.

Get Written Proof of Your No-Claims Discount

Your no-claims discount is probably the biggest single thing you carry from one insurer to the next, so secure the evidence before you cancel anything.

• Request proof in writing. Some insurers issue it automatically when a policy ends, others only on request. The new insurer will need it to confirm your price, so ask early rather than waiting for the old policy to close.
• Check the number of years recorded. If the figure is wrong, correcting it afterwards is slow and frustrating, so get it right before the switch.
• Keep the document safe. If the new policy falls through or you change your mind, you may need the same proof again.
• Mention a protected discount. If you pay extra to protect your no-claims bonus, tell the new insurer and check how they treat it. Our article on how a no-claims discount works and whether to protect it covers the detail.

Check Cancellation Fees and Admin Charges

Switching mid-policy is allowed, but leaving early carries a cost that varies widely between insurers. Work it out before you sign anything new.

• Read the cancellation section of your current policy. Fees, refund methods and notice requirements are set by each insurer, and they differ more than most people expect.
• Expect admin charges. Mid-term adjustments typically cost around £15 to £50, and online changes often cost less than a phone call. Ask what closing the policy early costs as well, since similar charges often apply.
• Run the sums both ways. If the cancellation fee, plus any deduction from your refund, swallows most of the gap between the two premiums, waiting until renewal may leave you better off.
• Check the new insurer’s charges too. A cheap quote loses its appeal if the insurer charges heavily for the adjustments you are likely to need during the year.

Compare Cover Level, Not Just the Headline Price

A lower premium means nothing if the cover behind it is thinner. Put the two policies side by side and work down this list.

• Confirm the cover level matches. Third party is the legal minimum and covers damage or injury you cause to other people, vehicles, animals or property, but it does not cover repairs to your own car. A cheap third party quote is not a like-for-like alternative to comprehensive cover.
• Compare the excess on each policy. The compulsory and voluntary parts add together, and a policy with a low premium and a high excess can cost you more after a claim than the saving you made across the year.
• List the add-ons. Courtesy car, windscreen, legal expenses and breakdown cover are priced differently by different insurers, and something included free in one policy may be a paid extra in another.
• Check the driving abroad position if it applies to you. All UK motor policies give the minimum third party cover in the EU and several other European countries, including Norway, Switzerland, Serbia and Iceland. Anything beyond that, such as theft or damage to your own car while abroad, depends on the policy. You do not need a green card for the EU, Andorra, Bosnia and Herzegovina, Iceland, Liechtenstein, Montenegro, Norway, Serbia or Switzerland, but valid insurance is still required.
• Use current prices. ABI data for the first quarter of 2023 showed motor premiums up 16% year on year, so a quote from months ago tells you little about the market now.

When you gather quotes, comparison sites can speed the process up, but they have blind spots. Our article on using comparison sites without the pitfalls explains what they show and what they leave out. If every quote comes back higher than you expected, our guide to ways to lower your car insurance premium sets out options such as adjusting the excess, mileage or car before you move insurer.

Time the Switch So Your Cover Never Lapses

This is the one item with legal consequences, so treat the timing as the most important part of the checklist.

• Know the rule. Under continuous insurance enforcement, a registered vehicle must be insured unless it is declared off the road with a SORN.
• Set the new policy to start the day the old one ends. Do not cancel the existing policy until the new insurer has confirmed the start date and you have the documents in hand.
• SORN the car if it is genuinely off the road. If a vehicle is not being driven or kept on public roads, declaring it off the road removes the insurance requirement for that period.
• Remember the consequences of a gap. Driving without insurance is an offence and carries penalties, and you will still have to pay for your insurance on top of any fine.
• Check the switch registered. Insurers must record motor policies on the motor insurance database, and the police use it as evidence that a vehicle is covered. Once the new policy starts, check that your car shows as insured on askMID.

Watch for: If your insurer fails rather than you choosing to leave, act quickly. Administrators can end policies at short notice and will not renew them, and for comprehensive or fire and theft policies the Financial Services Compensation Scheme may pay only 90% of an eligible claim.

Make Sure Your Details Match on the New Policy

Insurers price and underwrite on the details you give them, and mismatches between your old policy and the new application cause trouble later.

• Carry the details across exactly. Address, where the car is kept overnight, annual mileage, occupation and who the main driver is should all describe the facts as they stand now.
• Take the postcode seriously. Insurers price on postcode-level risk and care about where the car is kept overnight, not just where your post is sent.
• Declare anything that affects the risk. That includes penalty points, claims and changes to how the car is used. If the insurer is not told about something relevant, the cover can be invalidated.
• Reflect current circumstances, not last year’s. If you have moved house, changed jobs or replaced the car since the current policy began, the new application should describe the situation as it is now, not as it was when the old policy started.
• Check named drivers. Names, relationships and usage should match reality, because the insurer needs an accurate picture of who drives the car and how often.

What Happens to Any Premium You Have Already Paid

Money paid upfront does not vanish when you switch, but the refund is rarely the full unused amount.

• Ask how the refund is calculated. Insurers use different methods for returning unused premium, and the terms sit in your policy documents.
• Expect deductions. Charges for setting up and closing the policy are usually taken off before the refund reaches you, so the amount back is less than the months remaining suggest.
• Cancel only when the new cover is live. Cancelling first and sorting the new policy afterwards leaves you exposed, and if the switch then falls through you would have to buy cover from scratch, quite possibly at a worse price.
• You do not need to return the paper certificate. When a policy is cancelled mid-term, the cancellation is recorded on the motor insurance database, and the old requirement to send the certificate back no longer applies.

Start by digging out your renewal documents and asking your current insurer for written proof of your no-claims discount. With both in hand, you can collect quotes on a genuinely like-for-like basis and move without a single day uncovered.

Questions answered

Can I cancel my car insurance and switch insurers at any time?
Yes, you can change insurers before your policy ends. Check your policy’s cancellation terms first, because fees can apply and any refund is usually reduced by deductions.

Will switching insurers lose me my no-claims discount?
No. Ask your current insurer for written proof of the years you have built up and pass it to the new insurer. If you pay to protect the discount, tell the new insurer and check how they treat it.

What happens if my cover lapses for a day between policies?
A registered vehicle must be insured at all times unless it is declared off the road with a SORN. Driving without insurance is an offence carrying penalties, and you still have to pay for insurance on top of any fine.

Do I have to send back my old insurance certificate?
No. When a policy is cancelled mid-term the cancellation is recorded on the motor insurance database, and the old requirement to return the certificate no longer applies.
