New Build Snagging Survey – Identify Defects Before Completion

What is a Snagging Survey?

A snagging survey is a detailed inspection of a newly built property designed to identify defects before you move in or while your warranty is still active. "Snags" range from minor cosmetic problems — such as poorly applied paint, scratched glass, or uneven tiling — through to more significant functional issues like improperly fitted doors, faulty plumbing connections, or inadequate drainage.

Even though a new build has passed building regulations approval, the standard of workmanship can vary significantly between developments. A snagging inspection provides an independent, room-by-room assessment of the build quality, producing a formal report that lists every defect found.

This report gives you the evidence you need to require the developer to carry out repairs under the terms of your NHBC, LABC, or Premier Guarantee warranty. Without a professional snagging list, defects can go unnoticed until the warranty period expires, leaving you to fund repairs yourself.

What Does a Snagging Survey Inspect?

A snagging surveyor will carry out a methodical inspection of every accessible part of the property. The report typically covers:

• Internal finishes: Plastering quality, paintwork, skirting boards, architraves, and tiling alignment.
• Doors and windows: Correct fitting, smooth operation, seals, handles, and locking mechanisms.
• Kitchen and bathrooms: Unit alignment, worktop joints, silicone seals, tap operation, and drainage flow.
• Plumbing and heating: Radiator operation, boiler installation, pipe connections, and water pressure.
• Electrics: Socket placement, switch operation, consumer unit labelling, and smoke alarm testing.
• External works: Brickwork, pointing, render, guttering, downpipes, driveways, and fencing.
• Loft space: Insulation coverage, ventilation, and any visible defects in roof timbers.
• Communal areas: For flats, shared hallways, stairwells, and bin stores may also be reviewed.

When Should You Have a Snagging Survey?

The timing of your snagging inspection matters. You have two main options:

Pre-completion snagging

The strongest option. If the developer allows access before legal completion, a pre-completion snagging survey means defects are identified and can be fixed before you pick up the keys. This avoids the disruption of having tradespeople in your home after you have moved in. Not all developers permit pre-completion access, but it is always worth requesting.

Post-completion snagging

If pre-completion access is not available, you can arrange a snagging survey at any point after you move in. Most new build warranties (including NHBC Buildmark) require the developer to fix reported defects within the first two years. Booking your inspection promptly after moving in gives the developer maximum time to schedule and complete repairs.

Snagging Survey vs HomeBuyer Surveys

A snagging survey and a standard home survey serve different purposes. Choosing the right one depends on whether you are buying a new build or an existing property.

If you are buying an older property, a RICS Level 2 HomeBuyer Survey or a RICS Level 3 Building Survey will be more appropriate. For new builds, a snagging survey is the right choice. If your lender requires a valuation, that is a separate process — see the mortgage valuation page for details.

Typical Snagging Survey Cost (£300–£900+)

Snagging surveys generally cost between £300 and £900+, depending on the property size and the level of detail required. The typical range may vary based on:

• Number of bedrooms: A one-bedroom flat is quicker to inspect than a four or five-bedroom house.
• Property type: Detached homes with gardens, garages, and outbuildings take longer than apartments.
• Development stage: If external areas are incomplete, a follow-up visit may be needed.
• Report detail: Some inspections include thermal imaging or drainage checks at additional cost.

Exact pricing is confirmed after the surveyor reviews the property details. Compared to the potential cost of fixing unresolved defects yourself — which can run into thousands of pounds — a snagging survey is a modest investment in protecting your new home.
