Short answer: most UK snagging surveys cost between £250 and £600, with the average sitting around £394. The exact quote depends on the size of your home, where it is, and who's doing the inspecting. Here's how the pricing works — and what the alternatives look like.
Almost every snagging company bands its pricing by bedrooms. These are the ranges you'll see quoted across the UK in 2026:
Indicative ranges gathered from published UK snagging-company price lists and cost guides — always get a written quote, and check whether it includes VAT.
Pricing is almost always banded by bedrooms. More rooms means more hours on site — a large detached home can take a full day to inspect properly, and the price reflects it.
London and the South East usually carry a premium — often around £50 or more — and some companies add travel charges outside their core patch.
Inspections carried out by RICS-regulated surveyors typically cost more than those from experienced but unregulated snagging inspectors. Both can produce excellent reports; the regulated badge adds weight (and cost).
Thermal imaging, drone roof inspections and re-inspection visits (to check the builder's fixes were actually done) are often priced separately, and can add £50–£150+ to the bill.
Some companies quote including VAT, others add 20% at checkout. When you compare quotes, make sure you're comparing the final price.
A pre-completion inspection sometimes costs slightly more than a post-completion visit because of the coordination involved with the builder — but it catches faults before you've legally completed.
A good inspector walks your home for several hours with kit most of us don't own — damp meters, laser levels, thermal imaging — and delivers a photographed report that references the NHBC Standards your builder signed up to. It's common for a professional to find well over a hundred defects in a home where the owner spotted a few dozen.
Whether that's worth it for your home and budget is a bigger question — we've written an honest breakdown in should I pay for a professional snagging report? The one-line version: if the budget allows, it's rarely money wasted; and either way, the ongoing snag list stays your job.
Most snags don't need a thermal camera to find — they need someone methodical, with a checklist, a torch and a phone. Our free room-by-room snagging checklist covers what to look for in every room, and unlike a one-day professional visit, you can re-inspect every month of your two-year builder warranty period for free.
SnagBoss turns that DIY inspection into a professional result: a structured, photographed, dated report your builder takes seriously — for a small fraction of the cost of a single professional survey. See pricing for the comparison.
SnagBoss walks you room by room, attaches a photo to every defect, and produces a report your builder can't wave away — no £400 inspection required.
