Buying your car insurance three weeks ahead of the start day is likely to get you the cheapest price from a comparison site, slashing the cost of your premium in half, an MSE investigation which scoured millions of quotes reveals.
But remarkably, being overly organised and getting your insurance too early could mean you overpay by £100s – while leaving it to the last minute will likely leave you paying the highest price.
We’ve analysed more than 18 million quotes from January to May after requesting the data from three of the biggest price comparison websites – Confused.com, Compare The Market and MoneySupermarket. All three had near-identical trends in pricing, with an optimum time to buy your car insurance – closely aligned to how much of a risk you’re deemed to be, and when the highest number of insurers will provide quotes.
Buying from a comparison site is one of the best ways to bag cheap insurance. See our Cheap Car Insurance guide for more tips to cut the cost.
What does the data show?
Based on an average price for the millions of quotes returned on the price comparison sites, the cheapest time to buy your policy is 21 days before the start date, an average of £589 – £531 cheaper compared to buying it 30 days in advance, the earliest you can usually get a quote on comparison sites. Get it on the day it’s due to start and it’s an eye-watering £1,156 – £567 more expensive on average than at the optimum time.
Note: Of course, these figures are averages and as your premium is tailored to you and your personal circumstances, your savings will likely be different. However, the general principle of when to buy your insurance still applies.
Martin: ‘Avoid being a last-minute loser’
MoneySavingExpert.com founder Martin Lewis said: “Car insurance pricing is based on a mix of ‘actuarial risk’ and which section of the market is being targeted. To find the risk they look for patterns, and we’ve now uncovered that one of those is how early you get a quote before renewal.
“To avoid being a last-minute loser, everyone with car insurance should, at the very least, put a note in their diary 25 days before renewal to sort it within a week.”
Why is there a price difference?
Quotations are based on a number of factors, such as car type, driving history, where you live and much more – see our Cheap Car Insurance guide for full info.
We asked Compare The Market, Confused.com, MoneySupermarket, Direct Line, Aviva, LV, More Than and Admiral why the price differed depending on how far in advance you got the policy. All told us generally the same thing.
It’s all based around risk – buying it three weeks before you need it suggests you’re more careful and organised, while leaving it to the last minute means you’re seen as higher risk, with some insurers telling us they’ve seen a direct link between drivers who leave sorting their insurance to the last moment and a higher number of claims.
As for why the super-prepared are being penalised for getting a quote 30 days in advance, it’s basically because there are fewer insurers returning quotes at that stage.
LV said: “Our historic claims data shows that riskier drivers renew their policies nearer to renewal date.”
More Than said: “Our data proves that drivers who obtain quotes on the same day their insurance expires present a greater risk and this is reflected in their premium price.”
Direct Line said: “Our claims data is based on years of experience and millions of policies and we see a correlation between last-minute purchasing and higher frequency and severity of claims.”
Will buying insurance 21 days in advance guarantee the best price?
Unfortunately there are no guarantees as prices can change frequently, but it definitely helps to avoid being stung with a hefty premium. Here are three steps to help you bag the cheapest premium:
- Lock in a rate 60 days ahead. Two insurers – Aviva* and Quotemehappy – let you lock in a rate 60 days before, without any obligation to take up the offer. So just lock in a few quotes to benchmark a price. See our list of other insurers that let you lock in 30 days in advance.
- Check your renewal price. It’s usually sent 28 days before it’s due – call your provider if you don’t get it.
- 21 days before you need cover to start, use the comparison sites. If you get a better quote than you’ve had so far, it’s likely to be the cheapest you’ll get.
Note: If you don’t want to actually commit to a policy 21 days in advance, you can just lock in a quote three weeks before you need it with no obligation to buy. And as long as your circumstances don’t change, eg, you don’t get a speeding ticket or have an accident before your new policy begins – the price won’t change.
More tips on getting the right price
- If you’re at renewal, it’s easy. NEVER automatically accept your renewal quote – use our car insurance tips to bag the cheapest deal.
- If you’re midway through your policy, check if you can save – for a £50ish admin fee (factor that in) you can usually cancel your existing policy and get the rest of the year refunded, provided you’ve not claimed.
- Combine comparison sites to speedily find your cheapest deal. There’s no single cheapest insurer, as prices are different for everyone, so check them all three weeks before you want your insurance to start.
- Then check the biggies comparisons miss. Direct Line* and Aviva* won’t appear on comparison sites, and can be competitive.
