Snagging Survey Cost Calculator

How much does a snagging survey cost?

A snagging survey is an independent inspection of a brand-new home that lists every defect – from cosmetic paint runs to missing insulation and out-of-tolerance brickwork – so the developer can put them right. The cost depends mostly on the size of the property, because a bigger home has more rooms, more fittings and more to check. As a rule of thumb a UK snagging survey runs from about £300 for a small flat to £600+ for a large house, with a re-inspection adding roughly £100–£150. This calculator gives an indicative range for your property so you know what to budget before you ask surveyors for a firm quote.

What drives the price

• Number of bedrooms / floor area – the single biggest factor. Studios and two-bed flats are cheapest; four and five-bed houses cost the most.
• House vs flat – flats usually cost a little less, as there is no roof, loft or external envelope for the surveyor to inspect.
• Re-inspection – a second visit to confirm the builder has fixed the snags. Some firms bundle one re-visit into the main fee; others charge £100–£150 extra.
• Region and access – London and the South East tend to sit at the top of the range, and difficult access can add to the time on site.

Worked example

A buyer completing on a new 3-bedroom house books a snagging survey and adds a re-inspection. The inspection itself is around £350–£450, and the re-inspection adds £100–£150, for a typical total of roughly £450–£600. If the survey uncovers 150 snags – not unusual on a new build – and the developer fixes them free under the two-year warranty, the fee is comfortably repaid by the value of work put right and the hassle avoided.

Frequently asked questions

How much does a snagging survey cost?

A professional new-build snagging survey typically costs between about £300 and £600 in the UK, depending on the size of the property. Smaller flats and two-bed homes sit at the lower end, while four and five-bed houses are at the top. Prices vary by surveyor and region, so always get a quote.

Is a snagging survey worth the money?

Usually yes. A snagging survey often finds dozens or even hundreds of defects, and the developer is contractually obliged to fix genuine snags free of charge, so the survey fee is small against the value of work put right. It is most valuable before you complete or within the first two years.

When should I book a snagging survey?

The best time is after the build is finished but before or just after legal completion, so snags are logged early. You can still book one at any point in the first two years, because most developers give a two-year warranty on defects during which they must fix reported snags.

How much is a snagging re-inspection?

A follow-up re-inspection, to check the developer has actually fixed the snags, typically adds around £100 to £150. Some surveyors include one re-visit in the original fee, so check what is bundled before booking.

Can I do my own snagging list instead?

You can, and it is better than nothing, but a professional snagger inspects areas a buyer cannot easily check – the roof, loft, external brickwork and technical tolerances – and produces a report developers take more seriously. Many buyers do a DIY list plus a professional survey.

Does the developer pay for the snagging survey?

No. You pay for the survey itself. The developer does not pay for the inspection, but they are responsible for fixing the genuine defects it identifies, at no cost to you, under the terms of your build contract and warranty.

Cost figures are indicative UK market ranges for 2026 and vary by surveyor, property and region – they are not a quote. New-build warranty and defect-period rights are set out in your build contract and warranty provider’s terms; see GOV.UK – How to buy a home for buyer guidance.
