What Is a Snagging List? New Build Buyers’ Essential Guide (2025)
Buying a new build home in 2025? Learn all about snagging surveys in the UK, how to build a snagging list, common problems with new builds—and when to inspect before moving in.
What Is a Snagging List (UK Definition)?
A snagging list (or snag list) is a detailed room-by-room inventory of defects and imperfections found in a new‑build home. These can range from simple cosmetic issues—scratches misaligned tiles—to more serious faults like unfinished insulation or misconnected pipes.
While developers inspect homes many defects persist until deliberate snagging is carried out. A professional snagging survey ensures anything below expected quality gets flagged before you move in.
When Should You Get a Snagging Survey?
➤ Pre-Completion Inspection (PCI)
Ideally get a Pre-Completion Inspection just before exchange—right after the builder considers work complete. It uses the New Homes Quality Code checklist and allows corrections before you move in.
➤ After Move-In
If PCI isn’t possible aim to book a full snagging survey within the first two years . That’s when your builder’s warranty applies and corrections are still enforceable.
Why Every New-Build Buyer Needs a Professional Snagging Survey
Hidden defects are common. On average new builds still have multiple snags—even though they’ve never had previous occupants.
Builders expect a snag list. Many only engage once you’ve pointed out issues—even apparently minor ones.
Stronger access to fixes. A documented professional report gives you leverage with the developer and strengthens your warranty claim.
What Does a Snagging Survey Look For?
A trained snagging surveyor inspects:
Interior finishes: paint drips uneven plaster skirting gaps kitchen/cupboard misfits
Doors/windows: alignment sealing gaps faulty locking
Floors/stairs: uneven levels creaks loose flooring
Plumbing: dripping taps blocked shower drains loose seals
Electrics: faulty sockets lighting issues underfloor heating faults checked via thermal imaging.
External and landscaping: loose roof tiles poor pointing garden fit external paintwork or drainage faults.
It produces a photographic schedule with descriptions and relevant NHBC or warranty standards .
Common Problems Found in New Builds
Despite being brand new many homes exhibit:
Cracked or faulty brickwork or pointing
Poor joinery misaligned doors or windows
Damage to cabinets scratched surfaces
Blocked drains incorrectly fitted pipes
Drafty insulation or thermal bridging
Loose tiles incorrectly installed fixtures
Even missing components like bath plugs.
Some customers report dozens or even hundreds of snags after move‑in.
Public platforms like TikTok now highlight shocking new-build flaws—missing drains misaligned fences and unfinished brickwork—even months after handover.
Investment Versus Cost: Is the Survey Worth It?
Element | Why It’s Worth It |
|---|---|
Survey cost (~£300–£600) | Small relative to new-build investment |
50–150 snags probable | Each could cost hundreds or more to fix |
Warranty leverage | Ensures problems are fixed free of charge |
Resale benefit | Report shows seriousness and professionalism |
Parking the survey is a false economy—the cost is modest and you could save significantly in remediation and warranty deductions.
How to Use Your Snagging List Effectively
Book before exchange if permitted (PCI)
Otherwise schedule ASAP after move-in
Send the snag list to your developer in writing
Track all rectifications ideally via formal written confirmation
Save reports and correspondence for warranty claims up to 2 years
Summary: The Snagging Checklist at a Glance
What it is: A list of faults and finishing defects in a new build
When to do it: Pre-completion or within two years of completion

What is a snagging survey in the UK?
A snagging survey inspects a new-build property for defects—both cosmetic and functional. A snag list documents each issue so the builder can correct them.
When should I get a snagging list done?
Ideally before legal completion (pre-completion inspection), or as soon as possible after moving in—within the first two years when your builder warranty applies.
Common problems with new builds UK—what are they?
Frequent issues include poorly installed doors/windows, uneven floors, cracked plaster, plumbing errors, faulty electrics, drainage faults, and cosmetic defects.
How much does a snagging survey cost?
Typically £300–£600 (depending on property size). It’s a small cost compared to potential repair bills or lost warranty claims.
