The question of when to look at car insurance quotes ahead of renewal turns out to have a surprisingly specific answer in the published data. It is not about which provider you pick or which route you use to find a quote; it is about how many days before the policy ends the quote is generated.
Why the timing changes the price
Pricing models in some UK insurers treat the timing of a quote as a meaningful signal in its own right. A driver looking three or four weeks ahead of expiry is interpreted differently from one looking on the day, and the difference flows through into the premium quoted, even when nothing else about the risk has changed.
What the published data shows
MoneySavingExpert reports an average difference of £346 between quotes generated around 25 days before renewal and quotes generated on the day of renewal, based on its analysis of approximately one million UK car insurance quotes between November 2025 and January 2026. Quotes around 21 to 26 days before the renewal date tended to be the most competitive in that dataset. Looking much further ahead, beyond about 60 days, prices tended to drift back upwards as some insurers priced in additional uncertainty.

What "renewal date" means in practice
The renewal date is the day the current policy ends, not the day the renewal letter arrives. Most insurers post a renewal notice around 21 to 28 days before expiry, which happens to overlap with the part of the window where the published quote data tends to be most competitive. The difficulty is that the renewal letter is also, for most drivers, the moment they first start thinking about it, by which point a meaningful part of the window has already passed.
Auto-renewal and the FCA reforms
Where no action is taken, most policies roll over automatically at the renewing insurer's quoted price. The FCA's general insurance pricing reforms (in force since January 2022) prevent an existing customer being charged more than a new customer for an identical product, but renewal pricing can still drift upwards year on year through changes to the product structure or to the way risk is rated.
What Revn does, and what it does not
Revn's role here is narrow: it stores the renewal date alongside the MOT, road tax, and service schedule, and reminds you ahead of expiry, so the 21 to 28 day window is genuinely available rather than missed. Revn does not generate quotes or recommend an insurer; an authorised insurance comparison feature is on our roadmap.

Why do quotes tend to be cheaper around 25 days before renewal?
Pricing models in some insurers treat the timing of a quote as a risk signal. A quote generated several weeks before expiry is interpreted differently from one on the day of renewal, and that flows through into the price.
Is it better to look at quotes more than 60 days before renewal?
In the published analysis, quotes generated very far ahead tended to be priced with extra uncertainty and were not consistently cheaper. The 21 to 26 day window was where quotes tended to cluster lowest.
