CoverMap1. Buy three to four weeks before your renewal date
Timing is the single biggest lever in the data. MoneySuperMarket analysed policies sold between June and August 2026 by how many days before the renewal date they were bought.
| Days before renewal | Median price paid |
|---|---|
| 0 (renewal day) | £713 |
| 1 | £649 |
| 10 | £454 |
| 20 | £408 |
| 25 | £409 |
| 26 | £382 |
| 27 | £401 |
| 28 | £420 |
| 30 | £448 |
Source: MoneySuperMarket – When to renew car insurance (policies sold June–August 2026). Checked October 2026.
The cheapest point was 26 days ahead. MoneySuperMarket separately puts the average saving from buying 26 days before renewal at £165 (enquiries April–July 2026). It notes that renewal notices usually arrive about 28 days before expiry and that most policies renew automatically, so it helps to note the date and start comparing before the notice arrives.
Other data shows the same pattern. Which? (August 2025) reported Go.Compare sales from April–June 2025: £355 on day 26 against £493 on renewal day, yet only 2% of customers bought on day 26. Which?’s August 2026 advice is to renew weeks, not days, early.
2. Compare quotes rather than auto-renewing
Consumer Intelligence research from June 2026, quoted by both MoneySuperMarket and Compare the Market, found 51% of consumers could save up to £483.75 (MoneySuperMarket’s figure) or £485 (Compare the Market’s) by comparing.
When you compare, keep the details identical across quotes: the same cover level, excess, mileage and drivers. Our car insurance guide explains cover levels and how to compare like with like.
3. Haggle at renewal
If your renewal quote is higher than others you’ve found, ask your insurer to match it. Which? lists haggling among its tips for cutting car insurance costs (August 2026).
4. Pay annually if you can
Paying in monthly instalments usually means paying interest. Which?’s June 2026 survey (carried out in February and March 2026) found car insurers charged APRs of 0% to 29.9%, with an average of 23%. Twenty of the 48 car insurers it surveyed charged 25% APR or more. As Which? puts it, “When paying monthly, you’re effectively borrowing the year’s premium.”
| Insurer | APR for monthly payments |
|---|---|
| Hiscox, NFU Mutual | 0% |
| Aviva | 15% average (19% maximum) |
| Admiral | About 15.5% |
| AXA | 16.1% |
| Churchill, Direct Line | 19.9% |
| Hastings Direct | 22.8% |
| John Lewis | 23.5% |
| Budget | 28.9% |
| Dial Direct, Hughes | 29.9% |
Source: Which? – Many car and home insurers still charging over 25% APR to pay monthly (16 Jun 2026). Rates can change; checked October 2026.
Which? says average rates have fallen by about 5 percentage points since April 2024, but its Rocio Concha said many motorists “are still being charged interest rates comparable to an expensive credit card”. If you need to spread the cost, check the APR as well as the headline price.
5. Set your voluntary excess with care
Your excess is the amount you pay towards a claim. Raising the voluntary part usually lowers the premium. MoneySuperMarket’s price data (from 2 July 2026) showed a median saving of £27.99 for moving voluntary excess from £0 to £250.
The trade-off: if you claim, you pay the voluntary excess on top of the insurer’s compulsory excess. Only set it at a level you could actually afford.
6. Use an accurate job title
Insurers price by claims history for each occupation, according to MoneySuperMarket, so the job title you give can change the price considerably. MoneySuperMarket’s examples range from £160.97 for clerics to £3,271.45 for bingo hall staff (September 2026).
You can choose between titles that genuinely describe your work. MoneySuperMarket gives the example of a chef describing themselves as a “caterer”, and Which? mentions “hairdresser” against “barber”. Confused.com’s July–September 2025 data showed “mechanic” quoted at £1,462 against £707 for “mechanical engineer”, but only where the title is accurate.
The line is honesty. Confused.com warns: “Just don’t make something up to get a lower price; that’s insurance fraud and could invalidate your cover.” MoneySuperMarket says false information can mean a refused or reduced claim, being treated as uninsured, or fraud charges. You must also tell your insurer if your job changes.
7. Give a realistic mileage
MoneySuperMarket found that cutting estimated annual mileage by 5,000 miles or more gave a median saving of £42.83 (price data from 2 July 2026). Which? also suggests limiting your mileage. Base your estimate on what you really drive: MoneySuperMarket stresses that “Everything you write in your car insurance application has to be the truth”.
8. Consider adding named drivers
MoneySuperMarket found quotes with three named drivers were £122 cheaper on average (enquiries April–July 2026). Named drivers must genuinely use the car occasionally. Naming an experienced driver as the main user of a car someone else mainly drives is fronting, which is fraud; our young driver guide explains the risks.
9. Price comprehensive cover, not just third party
MoneySuperMarket found upgrading from third party only to comprehensive saved a median £175.84 (price data from 2 July 2026). Its August 2026 sales show comprehensive at a median £511.84 against £867.93 for third party only.
10. Look at black box insurance
Which? (November 2025, analysing 6,868 driver profiles) found a telematics policy was the cheapest quote 42% of the time, by £228 on average. The advantage is largest for younger drivers and shrinks with age. Our black box insurance guide covers how scoring works and when premiums can rise.
11. Think about the car, security and your bonus
- The car’s insurance group. The AA (December 2024) says group 1 cars are generally cheapest to insure. See car insurance groups explained.
- Security and parking. The same AA guide suggests a garage, an alarm and glass etching, and avoiding modifications such as alloy wheels and spoilers.
- Your no claims bonus. Claim-free years cut the price, and how you use or protect them matters. See our no claims bonus guide.
Car insurance myths to avoid
“Third party only is the cheapest cover”
Often not. MoneySuperMarket, Compare the Market and Go.Compare all show comprehensive costing less on average than third party only in their 2026 data. Go.Compare’s Q2 2026 figures were £399 for comprehensive against £546 for third party only.
“Your renewal price is always a rip-off”
Since 1 January 2022, FCA rules have said your renewal price can’t be higher than the price your insurer would charge an equivalent new customer (our car insurance guide covers the FCA’s 2025 review). That doesn’t make your renewal the cheapest on the market. The rule only compares an insurer with itself, so shopping around still matters.
“Low mileage always means a cheaper policy”
Not reliably. Defaqto’s index found prices rose most for the lowest-mileage drivers in Q2 2026. Mileage is one factor among many.
“Any job title that lowers the price is fine”
Only titles that accurately describe your work are allowed. Anything else is misrepresentation. Confused.com warns it could invalidate your cover, and MoneySuperMarket says you could be treated as uninsured.
Frequently Asked Questions
When is the cheapest time to buy car insurance?
In MoneySuperMarket’s June–August 2026 sales data, the cheapest point was 26 days before renewal, at a median of £382, against £713 on the renewal day.
Is it cheaper to pay car insurance annually?
Usually. Which? (June 2026) found car insurers charged APRs of 0% to 29.9% for monthly payments, averaging 23%. Hiscox and NFU Mutual charged 0%.
Does a higher voluntary excess lower my premium?
Usually. MoneySuperMarket found raising voluntary excess from £0 to £250 saved a median £27.99. You pay that excess plus the compulsory excess if you claim.
Can I change my job title to get cheaper car insurance?
Only to another title that accurately describes your work, such as chef to caterer. Making up a job title is insurance fraud and could invalidate your cover, Confused.com warns.
Do loyal customers pay more for car insurance?
Not under current rules. Since January 2022 the FCA has required renewal prices to be no higher than the price for an equivalent new customer, and its 2025 review found renewing motor customers now pay less on average. Other insurers may still be cheaper.
Does adding a named driver reduce car insurance?
It can. MoneySuperMarket found quotes with three named drivers were £122 cheaper on average. Named drivers must genuinely be occasional drivers of the car.
