Thanks to the UK’s September number plate change, September is one of the busiest periods of the year for motorists buying new cars and renewing their insurance. Every year, hundreds of thousands of drivers head to dealerships for the latest registration plate, while millions more receive their annual renewal notices around the same time.
That also means insurers are incredibly busy. If you simply accept your renewal quote or leave shopping around until the last minute, you could end up paying far more than necessary.
The good news? A little forward planning can make a significant difference.
Why September is such a busy month for car insurance
September has long been one of the UK’s biggest months for new car registrations, thanks to the introduction of the new registration plate.
Many drivers buying a new vehicle also need a new insurance policy, while plenty of existing motorists reach their annual renewal date during this period. As a result, September is historically one of the two busiest months for car insurance renewals, driven by the annual surge in vehicle purchases.
For insurers, it’s peak season, for you, it means it’s even more important to get organised.
Don’t wait for your renewal date
One of the biggest mistakes drivers make is assuming they need to wait until their policy is about to expire before arranging new cover.
You don’t. In fact, leaving it until the final few days can actually increase the price you pay.
Insurance pricing isn’t just based on your driving history or your car. Insurers also look at your buying behaviour. Drivers who search ahead are generally viewed as lower risk than those scrambling to find cover the day before their insurance expires.
That’s why timing matters.
Start looking around 30 days before renewal
As soon as your renewal notice arrives, it’s time to start comparing. Around 30 days before renewal is often the cheapest point to buy a new policy, with the best prices generally available between 20 and 30 days before your cover expires.
Don’t wait until renewal day, even if you don’t buy immediately, getting quotes early gives you time to compare insurers without pressure.
Why insurers charge more at the last minute
It might seem strange that buying later often costs more, but insurers use huge amounts of historical data when calculating premiums. Drivers who leave insurance until the last minute are statistically more likely to make claims, so insurers often charge higher premiums to reflect that increased risk. The closer your renewal date gets, the fewer competitive offers you’re likely to see. Instead of rewarding procrastination, insurers reward preparation.
Never assume your renewal quote is the best deal
Your current insurer may have looked after you well for the past year, but that doesn’t automatically mean they’re offering the best price for the next one.
Since the Financial Conduct Authority introduced rules to prevent insurers charging loyal customers more than new customers for the same policy, renewal prices have become fairer. However, fair doesn’t necessarily mean cheapest. Different insurers assess risk differently. One company may consider your postcode favourably while another focuses more heavily on your occupation or annual mileage.
Comparing several quotes is still one of the easiest ways to save money.
Five things to check before buying
When comparing policies, don’t focus on price alone.
Take a few minutes to check:
- The level of cover included.
- Your compulsory and voluntary excess.
- Whether legal expenses or breakdown cover are included.
- Courtesy car arrangements.
- Any changes to your mileage or personal details.
Sometimes a slightly more expensive policy provides considerably better protection.
If you’ve found a better quote, tell your insurer
Before switching, contact your existing insurer. Many providers are prepared to review your renewal quote if you’ve found a cheaper like-for-like policy elsewhere. It only takes a few minutes and could save you money without changing insurers and if they can’t match the price, you’ll already have an alternative lined up.
Avoid auto-renewing without checking
Automatic renewal can be convenient, but convenience often comes at a price. If you do nothing, your insurer may simply roll your policy over for another year.
Before allowing that to happen, compare the market first. You may find better value elsewhere or discover that another insurer offers additional benefits for a similar premium.
September renewals reward early planning
September is one of the busiest times of year for car insurance, but that doesn’t mean you need to pay peak prices.
The best approach is simple:
As soon as your renewal notice arrives, spend a little time comparing quotes, ideally around 30 days before your policy ends.
You’ll have more choice, more time to negotiate, and a much better chance of finding a policy that offers the right cover at the right price. A few weeks of planning today could leave you with hundreds of pounds still in your pocket by the time your next renewal comes around.
