When do you need self-build insurance?
The moment you purchase a site you become responsible for what happens on it, so if anyone is injured on your land they can make a claim against you. This risk means most mortgage providers will require proof of at least fire only site insurance before releasing funds.
A new build is generally a property that has never been occupied. Even with extensive works, renovated or converted properties are not classified as new builds. This distinction can influence the terms of your policy, so it is important to confirm the classification of your property.
While some alterations and refurbishments are typically allowed under standard home insurance policies, anything more complex – be it a kitchen upgrade or a garage conversion – should be fully explained to your insurer.
Large extension projects can increase the risk of accidental damage, theft, and liability claims. Some insurers may continue coverage during smaller building works, but for larger projects, such as an extension, conservatory or loft conversion, additional cover may be required. Always check with your insurer before work starts to avoid invalidating your policy.
If you’re living in your property while work is taking place, insurers will usually want to know:
- The type of work being carried out
- The project value
- How long the work will take
- Whether contractors are being used

Our advice – How to get a quote
Based on our research during the week of 15 June 2026, getting a quote for self-build insurance can be an extremely time-consuming and tiring process. Essentially there are two ways to get a quote:
Option 1: Going direct (the hard way)
After spending a full week calling insurers, we found that most don’t offer self-build insurance directly to consumers, and those that do can have limited cover options. This level of research is not realistic for the average homeowner looking for a quote.
Going through a broker (the easy way)
By contacting brokers who have access to specialist underwriters, we were able to find a much wider variety of cover options that you simply cannot get directly from a provider.
So, our advice is simple: if you are looking for self-build insurance, we recommend using a broker to get the best deal.
