Yes, you do need a warranty when buying a new build home. Almost all new build properties in the UK come with a 10-year warranty and your mortgage lender will usually require one before approving your loan. For a new home warranty first time buyer purchase, this protection is standard and built into the buying process.
What Is a New Home Warranty and Do You Need One?
A new home warranty is an insurance-backed policy taken out by the developer before construction starts. It protects you, the buyer, against certain defects in the property after completion.
For a new home warranty first time buyer situation, the key points are simple:
- The developer arranges and pays for the warranty.
- You benefit from it when you complete on the property.
- Your mortgage lender will usually insist on it.
If you are wondering ‘do I need warranty new home protection’, the answer is yes for almost all new build purchases with a mortgage. Without it, most mainstream lenders will not release funds.
This is not something extra you need to arrange yourself. It should already be in place when you buy from a reputable developer.
Does a New Build Come With a Warranty?
Yes. Almost every new build home sold by a professional developer includes a 10-year warranty from a recognised provider.
Common providers include NHBC, LABC Warranty, Build-Zone, Premier Guarantee and Protek. All are accepted by mainstream UK mortgage lenders.
As a first time buyer new build warranty protection is not optional. It is part of the standard structure of the purchase.
If a developer tells you there is no warranty in place, you should raise this immediately with your solicitor and mortgage adviser.
What Does a New Home Warranty Cover – and What Doesn’t It Cover?
Understanding what is covered helps you avoid unrealistic expectations.
A new home warranty is split into two clear stages.
Years 1–2: The Builder’s Responsibility
During the first two years after you complete, the builder is responsible for fixing defects that breach the warranty provider’s standards.
This can include:
- Poor workmanship
- Certain non-structural defects
- Issues that fall below technical standards
If you notice a problem during this period, you contact the builder first.
Years 3–10: Structural Insurance Cover
From year three onwards, the policy shifts to insurance-backed structural protection. This covers serious structural defects such as:
- Foundation failure
- Load-bearing wall problems
- Structural roof defects
It does not cover:
- Wear and tear
- Minor cosmetic cracks
- Damage caused by you
- Routine maintenance
For a more detailed breakdown, see our explanation of what a structural warranty covers.
As a new home warranty first time buyer, the most important thing to remember is that cosmetic snags are different from structural defects.
How Long Does a New Build Warranty Last?
A standard new build warranty lasts 10 years from the date of completion.
That 10-year period is split into:
- Years 1–2 builder responsibility
- Years 3–10 structural insurance cover
Some higher-risk buildings now carry 15-year policies due to changes introduced under the Building Safety Act 2022. In simple terms, higher-risk buildings are usually residential buildings over 11 metres in height.
If you are buying a flat in a taller building, your solicitor will confirm what type of cover applies.
For most houses and low-rise flats, the 10-year structure remains the norm.
Does My Mortgage Lender Require a New Build Warranty?
Yes. All mainstream UK mortgage lenders require a recognised warranty provider for new build properties. This protects both you and the lender if a serious structural defect arises.
As a first time buyer, new build warranty requirement should not alarm you. It is standard practice across the market.
Your solicitor will check:
- The warranty provider is lender-approved
- The policy is valid
- The cover period aligns with completion
If you are buying from a reputable developer, this process should be routine.
What Is the Difference Between the 1-Year and 10-Year Warranty?
Buyers often refer to a “1-year warranty” and a “10-year warranty” as though they are separate products. In reality, they are two phases of the same policy.
Years 1–2: The builder fixes defects that fall within the warranty provider’s standards.
Years 3–10: The insurer covers major structural defects.
If your builder fails to respond in years 1–2, you can escalate to the warranty provider. Guidance on what homeowners can do if a builder is not honouring a 1 year warranty explains the steps clearly.
Understanding this split is central to any new home warranty first time buyer scenario.
Can I Claim on My New Build Warranty After I Move In?
Yes, if the issue falls within the terms of the policy.
The process usually works like this:
- Identify the defect.
- Notify the builder in writing during years 1–2.
- Escalate to the warranty provider if the builder does not respond.
- Provide evidence such as photographs and written details.
In years 3–10, you contact the warranty provider directly for structural issues.
Keep clear records of communication. Never rely on verbal conversations alone.
What Should I Do If My Builder Won’t Fix a Defect?
Start by contacting the builder formally in writing. Be clear about the issue, when it was noticed and what outcome you expect.
If the builder does not respond or refuses to act within years 1–2, you can escalate to the warranty provider.
The warranty provider may instruct the builder to act, arrange an inspection or intervene directly if necessary.
Following the correct process protects your position.
What Happens to My Warranty If I Sell the House?
The warranty transfers automatically to the new owner.
You do not need to cancel or reissue the policy. When you sell, your solicitor will provide the warranty certificate to the buyer’s solicitor.
This is explained in more detail in our article on are warranties transferable when buying a new home.
For a new home warranty first time buyer, this means your property remains attractive to future buyers if you sell within the 10-year period.
Is There Anything I Should Check Before Completion?
Before you complete on your purchase:
- Ask your solicitor to confirm the warranty provider.
- Request a copy of the warranty certificate.
- Confirm the start date of the cover.

Understanding Your Protection as a New Build Buyer
Buying your first home is a major milestone. The legal language around warranties can feel complicated, but the core principle is simple.
A new home warranty protects you against serious defects. It lasts 10 years. Your lender requires it. It transfers automatically if you sell.
As a new home warranty first time buyer, you do not need to arrange the policy yourself. You simply need to understand how it works and what to do if something goes wrong.
