Do new builds need home insurance?
Yes, absolutely. Despite the common misconception that a new build warranty (such as an NHBC Buildmark policy) provides comprehensive protection, new build homes require separate home insurance just like any other property. Your mortgage lender will almost certainly require buildings insurance as a condition of your mortgage, and you will need contents insurance to protect your belongings.
The new build warranty and your home insurance policy serve different purposes. The warranty covers structural defects resulting from the builder's work, while home insurance covers damage from insured events such as fire, flood, storm, theft, and escape of water. There is some overlap in certain areas, but neither fully replaces the other.
Understanding the NHBC Buildmark warranty
The National House Building Council (NHBC) is the most well-known provider of new home warranties in the UK, covering approximately 80% of new builds. The Buildmark warranty provides protection in three distinct phases over a ten-year period.
Years 1-2: Builder's warranty period
During the first two years, the builder is responsible for fixing any defects that do not meet NHBC standards. This covers issues like faulty plumbing, poor brickwork, inadequate insulation, or other construction defects. If the builder fails to put things right, NHBC will step in and arrange the work at their cost. This is essentially a guarantee of the builder's workmanship.
Years 3-10: Structural insurance
From year three to year ten, the NHBC warranty provides insurance cover for physical damage to the home caused by a defect in certain specified structural elements — the foundations, load-bearing walls, external render, roof structure, and other critical components. This is a narrower cover than the first two years and does not include cosmetic issues or non-structural defects.
It is important to understand that the NHBC warranty does not cover damage from fire, flood, storm, theft, subsidence (unless caused by a structural defect), or any of the other standard home insurance perils. These risks need to be covered by your separate home insurance policy.
Other warranty providers
While NHBC is the largest warranty provider, several other organisations offer new build warranties including LABC, Premier Guarantee, Zurich, and Checkmate. These warranties offer broadly similar protection to the NHBC Buildmark, though the specific terms, coverage periods, and claim processes differ between providers. Your conveyancer should confirm which warranty applies to your new build and provide you with the full warranty documentation before completion.
When to arrange home insurance for a new build
You need to have buildings insurance in place from the date of legal completion — the day you become the legal owner of the property. Most mortgage lenders require confirmation of buildings insurance before they will release the mortgage funds, so you should arrange this well before your completion date.
For exchange of contracts (which typically happens before completion on new builds), some buyers also take out insurance to protect their interest in the property. This is not always required but can provide peace of mind, particularly if there is a long gap between exchange and completion.
If you are purchasing off-plan (before the property is built), you do not need insurance until the property is completed and you take legal ownership. The developer's own insurance covers the building during construction.
Getting the rebuild cost right
One of the advantages of insuring a new build is that the rebuild cost is relatively straightforward to determine. Your developer or NHBC warranty documentation will typically include a reinstatement figure, and the property has been recently built to current building regulations, so there are no unknowns about construction methods or materials. However, it is still worth checking that the rebuild cost figure used for insurance purposes is accurate and up to date, as building costs have risen significantly in recent years.
Special considerations for new builds
Snagging and defects
New builds often have snagging issues — minor defects and unfinished work that the builder needs to rectify. These are covered by the builder's warranty (particularly in the first two years) rather than by home insurance. Keep a detailed snagging list and ensure the builder addresses all items within the warranty period.
Settlement and movement
New properties can experience minor settlement as the building materials cure and the foundations settle into the ground. This is normal and does not usually cause significant structural issues. However, if settlement leads to cracking or other damage, it may be covered by either the NHBC warranty (if caused by a construction defect) or your home insurance (if it constitutes subsidence). Your insurer and warranty provider can advise on which applies in specific circumstances.
Landscaping and external areas
Many new builds are completed with basic landscaping that the homeowner then enhances — adding fencing, paving, planting, sheds, and other external features. As you add these improvements, you should review your home insurance to ensure they are included in the cover. A shed full of tools or a newly built garden wall may need to be covered under your buildings or contents insurance.
New build insurance costs
Home insurance for new builds is generally slightly cheaper than for older properties because new builds are constructed to modern standards with good quality materials, they have modern wiring and plumbing (reducing fire and escape of water risks), they meet current building regulations for structural integrity and energy efficiency, and they are typically in good condition with no maintenance backlog. However, the premium will still depend on all the standard factors — location, rebuild cost, contents value, chosen excess, and any optional extras.
Finding the right policy
A home insurance broker can help you find the right policy for your new build, ensuring that the cover complements your NHBC or equivalent warranty without unnecessary duplication.

Why Is Understanding Home Insurance for New Build Properties Important?
Making informed decisions about home insurance for new build properties can have a significant impact on your financial wellbeing, both in the short term and over the long run. In the UK, where regulation and consumer protections are strong, understanding your rights and options puts you in a much better position.
Many people make decisions about home insurance for new build properties based on incomplete information, assumptions, or advice from well-meaning friends and family who may not fully understand the current rules and options. Taking the time to research properly can save you thousands of pounds over the lifetime of a product or arrangement.
The UK financial market is competitive, which means there are usually multiple options available for any given need. The challenge is identifying which option genuinely suits your circumstances rather than just choosing the first or cheapest.
What Are the Key Considerations in the UK?
When it comes to home insurance for new build properties in the UK, there are several important factors that are specific to the British market and regulatory environment. These considerations can significantly affect the options available to you and the value you receive.
UK-specific factors include the tax regime (income tax, capital gains tax, inheritance tax, and stamp duty land tax), the regulatory framework (FCA rules, consumer duty, and FSCS protection), and the structure of the market (whole-of-market brokers, restricted advisers, and direct providers).
- Tax implications — understand how UK tax rules affect the cost and benefit of your decision
- FCA regulation — ensure any provider or adviser you use is authorised and regulated
- Consumer protections — know your rights under the Consumer Duty, FSCS, and FOS
- Market comparison — the UK market is competitive, so always compare multiple options
- Professional advice — for complex decisions, regulated advice provides accountability and recourse
- Documentation — keep records of all communications, agreements, and transactions
What Are the Most Common Mistakes to Avoid?
Experience shows that people consistently make certain mistakes when dealing with home insurance for new build properties. Being aware of these common pitfalls can help you avoid costly errors.
One of the most frequent mistakes is not shopping around. UK consumers who compare at least three quotes typically save 20-40 percent compared to those who accept the first offer. Another common error is focusing solely on price rather than the overall value and suitability of the product.
- Not comparing enough options before committing
- Choosing the cheapest option without understanding what is excluded
- Failing to read the terms and conditions and key facts document
- Not disclosing relevant information on the application
- Forgetting to review and update arrangements as circumstances change
- Trying to handle complex situations without professional advice
