Why New Builds Still Need Checking

New-build developments are typically built to tight schedules, and quality control varies significantly between developers and even between phases of the same development. A Level 1 Condition Report, or a dedicated snagging inspection, gives you an independent, room-by-room record of defects — separate from the developer's own sign-off process — before your warranty period starts running down.

Warranties have deadlines Most new-build warranty schemes (NHBC, Premier Guarantee, LABC) give you a limited window — often just the first two years — to report many defects. Getting a full snagging list early protects your rights under that warranty.

Common Snagging Issues in London New Builds

  • Poor quality plastering, uneven walls and visible joint lines
  • Doors and windows that don't close or seal properly
  • Incomplete or leaking sealant around baths, sinks and windows
  • Paint splashes, damaged surfaces and unfinished decorating
  • Faulty or incomplete electrical fittings and sockets
  • Poorly fitted kitchen units and worktops
  • Inadequate ventilation, particularly in bathrooms and kitchens
  • Damaged flooring from the construction process
  • External issues — uneven paving, poor drainage falls, incomplete landscaping

Snagging vs a Full Building Survey

For a new build, a dedicated snagging inspection (similar in scope to a Level 1 Condition Report but with a detailed itemised defect list) is usually more useful than a full Level 3 Building Survey, since there's no historic structure, damp or timber decay risk to assess. We tailor the inspection to focus on finish quality, fittings, and compliance with the specification you were sold.

When to Book Your Snagging Inspection

  • Before legal completion — ideally during your pre-completion inspection, so issues can be raised before you're legally committed
  • Shortly after moving in — a second inspection after living in the property for a few weeks often reveals issues that only appear with use (doors settling, heating performance, snagging missed in the rush to complete)
  • Before your 2-year warranty anniversary — a final check to catch anything before the initial warranty window narrows

What to Do With Your Snagging Report

Submit the itemised list to your developer's customer care team in writing, referencing your warranty provider if issues aren't resolved promptly. Keep dated photographic evidence and correspondence — this becomes essential if you need to escalate to your warranty provider or the New Homes Ombudsman.

New Build FAQs

FAQs on New Build Snagging in London

What is a snagging survey?

A snagging survey is an independent inspection of a new-build property to identify construction defects and finishing issues, from minor cosmetic snags to more significant workmanship problems.

How is a snagging survey different from a Level 1 Condition Report?

A snagging inspection focuses specifically on new-build defects and finish quality, while a Level 1 Condition Report gives a broader traffic-light assessment of an existing property's overall condition.

When should I book a snagging inspection in London?

Ideally as soon as possible after legal completion, and again near the end of your developer's defects liability period, usually around the 2-year mark, to catch anything that's emerged since.

Is the developer obliged to fix snagging issues?

Most new-build warranties require the developer to fix defects reported within the defects period, so having an independent list from a survey strengthens your case.

How many snags are typical on a new London development?

It varies widely by developer and build quality, but it's common to find dozens of minor and moderate issues even on well-regarded developments, which is why an independent check is worthwhile.

Can a snagging survey be done before legal completion?

Sometimes, if the developer allows access, though most snagging inspections happen shortly after completion when you have full access to the property.
