Never Auto-Renew Your Car Insurance
You might not believe how much allowing your insurance company to auto-renew your insurance will cost you. On average it's £113 a year, and one driver reported an auto-renewal fee of £1,200, compared to a new policy with the same company of just £690 - that's a 43% saving just by requesting a new car insurance quote.
Insurance companies justify this by declaring the rise as an "administration" fee - often disguised as a "renewal" fee. Vote with your feet and make sure you get a quote renewal when your premium is due - and if your premium is too high, tweet about it to shame the company.
