- Never auto-renew. Loyalty is penalised, not rewarded.
- Start shopping around roughly three to four weeks before renewal.
- Getting your job title right can change the price for the same work.
Car insurance is the clearest example of the loyalty penalty in UK personal finance. Renewal quotes for existing customers are frequently higher than the same insurer’s price for a new customer — for the same driver, the same car and the same cover.
Rules now require insurers to offer renewing customers a price no higher than they would offer an equivalent new customer through the same channel. That has helped, but shopping around still routinely beats staying put.
Time it properly
Insurance quotes tend to get more expensive the closer you get to the start date, because insurers treat last-minute buyers as higher risk.
Analysis of quote data has consistently found that prices are lowest around three to four weeks before the policy starts, rising sharply in the final days. Your renewal notice must arrive at least twenty-one days beforehand, which fits neatly.
So: get your renewal notice, then immediately start comparing. Buy the new policy with a start date matching your renewal date — you can normally set a future start date.
How to shop around properly
- Use two or three comparison sites, not one. They cover different panels of insurers.
- Check the insurers who are not on comparison sites. Some of the largest do not appear on them and must be approached directly.
- Take the cheapest quote back to your current insurer and ask them to match it. Sometimes they will.
- Route the purchase through a cashback site, which for insurance is often worth a substantial amount.
Details that change the price
These are legitimate adjustments, not tricks. Everything you enter must be true — but there is often more than one accurate way to describe something.
- Job title. Different accurate descriptions of the same job can produce noticeably different quotes. Try a few honest variations and pick the cheapest that genuinely describes what you do.
- Mileage. Estimate honestly based on your actual annual mileage. Many people overstate it out of caution and pay more. Understating it is a misrepresentation, so do not.
- Add a named driver. Adding a lower-risk experienced driver who genuinely uses the car sometimes reduces the premium. Never list them as the main driver if they are not — that is “fronting”, it is fraud, and it will void the policy.
- Pay annually if you can. Monthly payment is credit, and the APR is often high. Paying in one go is usually meaningfully cheaper.
- Consider the voluntary excess. A higher excess lowers the premium, but only raise it to an amount you could genuinely pay tomorrow.
- Check comprehensive against third party. Counter-intuitively, comprehensive cover is often cheaper, because of who tends to buy each. Always price both.
- Where the car is kept and whether it is on a drive or garage.
- Add security such as an approved alarm or tracker if the discount justifies it.
Protect your no claims discount — carefully
Protecting no claims costs extra and preserves the discount if you claim. Whether it is worth it depends on your discount level and the cost. Note that protection preserves the discount but does not prevent your base premium rising after a claim.
Build your no claims years and keep proof of them — you will need it when switching.
Telematics and mileage-based policies
Black box policies monitor driving and can substantially reduce premiums for younger or lower-mileage drivers. The trade-off is monitoring, and sometimes curfews or penalties. Read the terms carefully. For low-mileage drivers, pay-per-mile policies are worth pricing too.
Look past the price
The cheapest policy is not automatically the best. Check:
- The total excess, compulsory plus voluntary.
- Whether a courtesy car is included, and what kind.
- Windscreen cover and its excess.
- Whether you are covered to drive other cars.
- Personal belongings and key cover.
- The insurer’s claims-handling reputation, which matters far more than a small price difference on the day you need it.
Do not double up
Check whether you already have breakdown cover through a bank account, and whether legal expenses cover is duplicated by your home insurance. Add-ons sold alongside insurance are often available cheaper separately, or already held.
Above all
Answer every question truthfully. Non-disclosure or misrepresentation is the most common reason claims are refused, and an unpaid claim costs far more than any premium saving. If you are unsure how to answer, ask the insurer and keep a record of what they said.
