Snagging Survey (2026): Cost, What It Covers & a DIY Checklist

Last updated:

Quick answer

A snagging survey is a professional inspection of a new-build home that lists every defect (“snag”) for the developer to fix under warranty. It typically costs £300–£600 in 2026 depending on property size (HomeOwners Alliance market data, July 2026). Book it before or shortly after legal completion, then report snags to the builder. Most are fixable free within the first two years under your NHBC or equivalent warranty. You can also run a DIY snag list yourself.

How much does a snagging survey cost in 2026?

Professional snagging surveys are priced by the size of the property. The ranges below are third-party market figures, so confirm the exact fee with your chosen snagging inspector.

Property sizeTypical snagging survey cost
1–2 bedroom flat or house£300–£400
3 bedroom house£350–£500
4 bedroom house£450–£600
5+ bedroom house£600+

Indicative market ranges (HomeOwners Alliance, July 2026), not HouseCheckup quotes. Some inspectors charge a flat day rate regardless of size.

What does a snagging survey cover?

A snagging survey checks the quality of finish and workmanship throughout a new build: uneven plasterwork, poor paintwork, badly fitted doors and windows, gaps in tiling and sealant, plumbing and drainage faults, non-functioning sockets, roof-tile and guttering defects, and external issues such as brickwork and driveways. The inspector produces a room-by-room report you hand to the developer. It is not a structural survey; it's about the builder finishing the home to the standard you paid for.

When should you book a snagging survey?

The best window is between exchange and legal completion, or in the first few weeks after you move in. Reporting snags early makes them easier to get fixed and starts the clock on your developer's obligations. Under the New Homes Quality Code and NHBC Buildmark, the builder is responsible for putting right defects reported in the first two years, so a prompt, documented snag list protects you.

Can I do my own snagging with a checklist?

Yes. Many buyers do a thorough DIY snag list and only bring in a professional for a larger or higher-value home. Our interactive new-build snagging checklist tool walks you room by room and produces an emailed PDF you can send straight to the developer. Take date-stamped photos of every snag and keep your correspondence.

Frequently asked questions

A professional new-build snagging survey typically costs £300–£600 in 2026, priced by the size of the property (HomeOwners Alliance market data, July 2026). A small flat sits near £300; a large house sits near £600 or above. Some inspectors charge a flat day rate.
For most buyers, yes. New builds routinely have dozens of minor defects, and a documented snag list makes it far easier to get the developer to fix them free under warranty. The survey fee is small next to the cost and hassle of chasing unrecorded snags later, though a careful DIY checklist can do much of the job on a smaller home.
Ideally between exchange and completion, or within the first few weeks of moving in. Early reporting makes snags easier to resolve and starts your developer's obligations under the New Homes Quality Code and NHBC Buildmark, which make the builder responsible for defects reported in the first two years.
A snagging survey checks the quality of finish and workmanship on a new build so the developer can fix defects under warranty. A house survey (RICS Level 2 or 3) assesses the condition of an existing property so a buyer can decide whether to proceed or renegotiate. New builds get snagging; older homes get a Level 2 or Level 3 survey.
