It's one of the most common assumptions I encounter: "It's brand new, so it doesn't need a survey." I understand why people think this. A new home should, in theory, have been built to current standards by professional tradespeople. And in many cases, they have been.
But "should have been" and "has been" are very different things – as any new build buyer who's dealt with a snagging list will tell you.
What Is a New Build Survey?
A new build survey (sometimes called a new build inspection or snagging survey) is a professional assessment of a newly built property before completion. Its purpose is to identify any defects, incomplete works, or deviations from building regulations and planning conditions before you legally complete your purchase.
It's important to distinguish this from the NHBC or similar warranty inspection. The NHBC builds warranty protects the developer, not just the buyer, and its inspectors are appointed and paid by the developer. An independent survey is carried out for your benefit exclusively.
What Do We Find in New Build Surveys?
You might be surprised. In a recent survey of a new build development in north Surrey, we identified 37 defects across a 4-bedroom detached house. Issues included:
- Missing fire-stopping around service penetrations through walls
- Incorrectly installed roof insulation leaving cold bridge issues
- Drainage connections made to the wrong outlet
- Defective external render with horizontal cracking at block joints
- Incomplete decoration and damaged finishes throughout
- Missing air bricks and blocked sub-floor ventilation
None of these were visible to the untrained eye. All of them needed to be rectified before completion.
"A new build snagging survey isn't about finding catastrophic problems. It's about holding developers accountable for delivering the quality of home that buyers are paying for." – James Thornton
The NHBC Warranty: What It Does and Doesn't Cover
Most new builds in England are covered by an NHBC Buildmark warranty (or similar from LABC, Premier Guarantee, etc.). This covers:
- Years 1–2: The developer is responsible for fixing defects that arise from their failure to comply with NHBC standards
- Years 3–10: The NHBC covers the cost of remedying physical damage caused by a major structural defect
The warranty is valuable. But it relies on you being able to demonstrate that a defect exists and that it was caused by a failure to meet standards. An independent pre-completion survey documents the property's condition precisely at the point of handover – giving you an invaluable baseline record.
When Should You Have a New Build Survey?
Ideally, before you legally complete on your purchase. Most new build developers will allow access to an independent surveyor before completion. If yours won't, that itself is a concern worth raising.
If you've already completed, a snagging survey in the first few weeks or months of ownership is still valuable. The earlier defects are identified and reported to the developer, the easier they are to have rectified under the warranty.
What Type of Survey Is Right for a New Build?
For a brand new property, a Level 2 HomeBuyer Report or a specialist new build inspection is usually appropriate. A Level 3 Building Survey is typically overkill for a genuinely brand new home (unless there are specific concerns about construction quality or the developer's reputation).
We carry out bespoke new build inspections that go beyond the standard snagging process to include a professional assessment of the construction quality, compliance with building regulations, and the condition of all elements.
Frequently Asked Questions
Legally, they can. However, most reputable developers will agree to independent access, and those that refuse often do so because they have concerns about what a surveyor might find. If access is refused, you should raise this with your solicitor and consider what it tells you about the developer's confidence in their own product.
A new build survey focuses on construction quality, compliance with building regulations and the developer's specifications, and identifying incomplete or defective works. It's less about assessing long-term structural condition (as the building is new) and more about ensuring the property has been built to the required standard.
Yes. We carry out new build inspections across the whole of Surrey, including new developments in Guildford, Woking, Reigate and Redhill, as well as new builds in Kent, Sussex and West London.
Research by the New Homes Quality Board suggests that around 99% of new build buyers report snagging issues after completion. The average number of defects identified in an independent new build survey is 60–100 items, ranging from minor cosmetic issues to more significant defects. Even the best developers leave work that needs finishing or correcting.
After year 2, you'd need to rely on the NHBC's 10-year warranty for major structural issues. For other defects, you may have a claim against the developer if they can be shown to have been present at completion. This is another reason why a pre-completion survey is so valuable – it establishes a clear record of condition at the point of handover.
