Do You Really Need a Survey on a New Build? (Yes. Here's Why)

When someone is buying a brand-new home — fresh from the builder, never been lived in — the idea of getting a survey can feel unnecessary. It's new, right? What could possibly be wrong?

Quite a lot, as it turns out. As Bristol surveyors who carry out new build inspections regularly, we see defects on brand-new properties all the time. Here's why you should always get a survey — even on a new build in South Gloucestershire, North Somerset, or any of Bristol's growing new developments.

The "It's New, So It's Fine" Myth

This is one of the most expensive misconceptions in the property world. New build properties are built to a budget, often under time pressure, by multiple subcontractors working simultaneously on site. The quality of construction varies enormously — from developer to developer, from site to site, and even from plot to plot on the same development.

Research from the NHBC (National House Building Council) and successive investigations by consumer groups has consistently found that a significant proportion of new build homes have defects at completion. A 2023 survey by the Home Builders Federation found that more than 90% of new build buyers reported snag items — and around half reported serious defects.

What Our Surveyors Find on New Build Inspections

When we carry out an inspection of a new build property — sometimes called a snagging survey or new build survey — we typically check:

• External fabric: pointing, rendering, roof coverings, drainage connections, paths and drives
• Internal fabric: plastering, tiling, floor finishes, joinery, doors and windows
• Services: visible heating, plumbing, and electrical installations
• Structural elements: visible defects to floors, walls, and ceilings
• Compliance: obvious non-compliance with building regulations

Common findings include poorly fitted kitchen units, misaligned doors and windows, incomplete sealing around baths and showers, roof tiles incorrectly fixed, and gaps in insulation. We've also found more serious issues — inadequate structural connections, defective drainage, and building regulation non-compliance.

When to Get Your New Build Survey

The ideal time to have a new build snagging survey is before legal completion — but after the property has been fully finished. This gives you the best chance of getting any defects remedied by the developer before you move in.

In practice, developers often resist access before completion. If this happens, you can still have the survey done shortly after completion and use the findings to pursue defect remediation under your warranty (typically NHBC Buildmark or a similar 10-year structural warranty).

Important: don't wait too long. The longer you delay, the more your warranty period runs down and the harder it can be to attribute defects to the original build rather than wear and tear.

But Doesn't My NHBC Warranty Cover Everything?

No — and this is a critical misconception. The NHBC Buildmark warranty (and similar products) covers structural defects for 10 years and other defects for just 2 years. It doesn't cover minor snags, cosmetic defects, or items that the developer's snagging process should have caught before completion.

More importantly: you need to know about defects to claim on your warranty. A professional survey gives you the documented evidence to pursue the developer — which, as anyone who has tried to get a developer to fix things knows, can be important.
