Yes — you should get a survey on a new build, but not the survey most buyers think of. New homes don't usually need a Level 2 or Level 3 condition survey; they need a snagging survey: a specialist inspection that documents every defect the developer is still obliged to fix.
“It's brand new — surely it's fine?”
Study after study puts the typical new build at 50–150 defects. Most are cosmetic — paintwork, sealant, adjustment of doors and windows — but the list regularly includes plumbing faults, missing insulation, poorly finished rooflines and drainage issues. New build warranties protect you, but only for defects that get identified and reported.
Snagging survey vs homebuyer survey
A Level 2 house survey assesses the condition of an existing home for a buyer weighing a purchase. A snagging survey is different: it measures a brand-new home against the standard the developer promised, producing a schedule of defects — the “snag list” — for the developer to remedy. For a new build, the snagging survey is almost always the right tool.
When to book
- Before legal completion — the gold standard. The developer fixes snags before you move in, and you hold maximum leverage.
- Within the first two years — still very worthwhile. Most builder warranties (NHBC Buildmark and similar) oblige the developer to fix defects you report in this window.
What it costs — and what it saves
A professional snagging survey costs £300–£600 depending on the size of the home. Set against 50+ documented defects the developer must fix at their cost — and the difficulty of getting anything fixed after your warranty window narrows — it is one of the highest-return checks in the whole buying process. See our full house survey cost guide for how snagging fees compare.
