We’re committed to finding the right cover for you and your home. That’s why we compare the biggest insurance providers in the country, including:
A new-build home is one that has been built but never lived in. It is also usually defined as a property that has been built in the last two years, though the exact definition can differ between lenders.
They are attractive to buyers who want modern furnishings and insulation, while it is also possible to buy them before they have been finished, allowing them to be partly built to your specifications.
New-builds are put into a special category for insurance purposes because there are certain ways that things can go wrong, including construction defects or features and fittings that don’t work properly. Many of these should be protected by the 10-year warranty which comes with most new-build properties – but that warranty doesn’t cover every eventuality.
If you buy a new-build, your mortgage provider will almost certainly require you to get a buildings insurance policy to protect the property for damage that’s outside your control, including fire, flooding and storms.
Buildings insurance for new-build properties, similar to its regular counterpart, covers the physical structure of the building, as well as permanent fixtures like bathroom suites or fitted kitchens, in the event they should be damaged by a freak event outside of your control.
You are insured for the ‘rebuild cost’, which is the cost of rebuilding the property from the ground up. This includes the value of the building materials and labour, but not the value of the land itself, so it is usually lower than the price you pay for the home. Find out more about calculating the rebuild cost of your home.
There are also plenty of extras you can include on top of your regular policy, if you choose:
Damage caused by fire, flood, storms, subsidence or heave, burst or frozen pipes
Outbuildings, gardens, swimming pools, ponds and patios, accidental damage, alternative accommodation during repair work
Most new properties in the UK are constructed by companies registered with the National House-Building Council (NHBC), and they come with a certificate that acts as a 10-year warranty protecting you from certain common problems.
The NHBC Buildmark certificate currently protects up to 80% of newly built or converted homes in the UK. It also protects a deposit of up to 10% before completion.
The NHBC certificate lasts for 10 years, and works like this:
For the first two years, whoever built your property will fix any issues that result from the work they did – for example, windows and doors not opening or closing properly
For the remaining eight years it works as an insurance policy covering you for problems with the property where it has not been built to technical specifications – but not wear and tear or other things like damage caused by fire or smoke. This means you must still take out buildings insurance
You’ll also be covered if you lose your deposit because your builders ended up bankrupt or insolvent – up to either 10% of the purchase price or £100,000, whichever is lower
There are plenty of factors at play when it comes to working out your home insurance premiums. These are the main things to think about:
Older materials are often more expensive
Non-standard materials are often more costly or require a specialist builder
These indicate a larger building and higher costs
Listed buildings are especially expensive to insure
The cost of your annual home insurance depends on plenty of factors, including size of the property, location and construction type. Cost will also depend on the policy type you buy, with combined buildings and contents being the most comprehensive but also the most expensive
Policy type | Average price |
|---|---|
Building and Contents | £268.43[4] |
Buildings | £221.95[5] |
Contents | £81.34[6] |
One good way to find cheaper buildings insurance premiums is to shop around and see if you can find a cheaper policy elsewhere, instead of auto-renewing with your existing provider. Here are our top tips:

It's cheaper to pay for your insurance annually, rather than monthly, as you won’t pay interest
A history of not claiming on your insurance is usually rewarded with a discount on your premiums
While new-build homes are usually well built and don’t often have problems, the NHBC certificate protects you if it was shoddily built. However, don’t be lulled into thinking you do not need separate insurance. Even brand new homes can face unforeseen events such as fires or flooding.
Recent data from the Association of British Insurers (ABI) revealed that claims for damage to homes from storms, heavy rain and frozen pipes reached £144 million between April and June 2024. This highlights the importance of getting proper home insurance cover to avoid nasty surprises. The annual premium that 51% of our customers paid in July 2024 was £268.43[4] and you can compare quotes in minutes to get the right insurance for your new-build home.

It’s not mandatory to take out home insurance but it is a very good idea – even on a new build.While new-builds come with a warranty that covers you for issues arising from the quality of the build, this won’t protect you for standard damage caused by things like fire or flooding. What’s more, your mortgage lender will almost certainly require you to take out buildings insurance before they lend you the money.
It's also a good idea to consider contents insurance for your possessions inside your home. This can protect belongings such as furniture, electricals, and white goods. These can all be expensive to replace and are worth protecting.
The cost of your home insurance depends on many factors, including where you live and what the house is like, but because newer homes tend to be better constructed and made out of readily available materials, it usually costs less on average to insure them.
New-build homes come with many advantages – they have modern designs which aim to be future proof, they’ve yet to suffer wear and tear, and there are certain government schemes available which can often make them cheaper to buy.
The NHBC is an independent body which provides warranties and certification for new homes. It also supplies inspectors for building regulations.
It is a non-profit distributing company, which means it is bound to put all its profits back into running its services. NHBC is authorised and regulated by the Financial Conduct Authority (FCA) and the Prudential Regulation Authority (PRA).
Most newly built properties come with a certificate, either from NHBC or one of the two other bodies which provide similar warranties. Without a warranty, you’re not protected if there are flaws in the construction of your home.
If your new-build property doesn’t have a buildmark certificate it makes it even more important to take out a home insurance policy that covers your building and contents.
You should also ask the builder why they aren’t part of the scheme before you buy the home. There could be good reasons for this, but you should ideally aim to find a property with a certificate as without one you may not be fully protected.
If you’re purchasing a property that’s been newly converted you may be eligible for a Buildmark certificate, however it may come with certain exclusions – you should become familiar with any policy documents and certificates so you know exactly how the cover applies.
In the first two years, the building company will put right any physical damage that occurs to your home as a result of it failing to build to the NHBC’s technical specifications. If it fails to do this then the NHBC will help under its resolution service.
In years three to 10, Buildmark provides insurance that should protect your home from damage that results from the property not being built to NHBC requirements. It does not cover accidental damage not arising from building issues or the damage or theft of contents.
