Get a quoteThe price comparison site Go.Compare has revealed the cheapest and most expensive days to renew your home insurance, based on the average annual cost of policies.
The data shows that the best time to buy your home insurance is 26 days in advance, with policies costing an average of £210 a year.
By contrast, waiting until the day your policy is due to renew could cost £259, which is around 23% more than buying 26 days earlier.
As the data shows, prices generally rise as the policy start date approaches. This shows the benefit of buying early to lock in a lower premium.
Here’s a breakdown of how prices change depending on how far in advance you purchase your policy:
Days until policy start date | Average (median) price paid* |
---|---|
26 | £210 |
25 | £213 |
28 | £214 |
29 | £214 |
27 | £218 |
23 | £217 |
24 | £220 |
Table note: *All average median costs are calculated from home insurance policies purchased through Go.Compare from 1 October 2024 and 31 March 2025. Home insurance policies refer to combined buildings and contents policies in this case. The table is listed in order from the cheapest to the most expensive quotes.
The average cost of home insurance has barely changed this year, even as weather-related claims continue to rise.
According to the Association of British Insurers (ABI), the typical price of combined buildings and contents cover fell by just £2 between April and June 2025 to £391. This is only £1 lower than the same period last year.
At the same time, insurers are paying out more in claims. In the second quarter of the year, home insurance providers paid £1.6 billion in total claims, compared with £1.5 billion in the first three months of 2025. Around £322 million of this was for weather-related damage such as storms, floods and frozen pipes, which is about 7% higher than in the previous quarter.
Although premiums have stayed stable so far, these figures show that extreme weather continues to drive up costs for insurers and could lead to higher prices in the months ahead.
