Do You Need a Survey on a New-Build? Snagging vs Level 1

Yes — new-builds still benefit from independent inspection. Before legal completion, a snagging survey lists defects and unfinished work for the developer to put right. Later, or for an already-completed newer home, a Level 1 Home Survey gives an independent condition check. They serve different purposes and timings.

New-builds are not defect-free

A new home being new does not mean it is free of defects. Workmanship issues, unfinished items and installation faults are common, and the most useful time to identify them is before you legally complete, while the developer is still responsible for putting them right.

An independent inspection gives you a documented, impartial list rather than relying solely on the developer's own checks.

Pre-completion snagging survey

A snagging survey is a detailed inspection of a new-build for defects, poor workmanship and incomplete finishes, producing a clear snagging list to pass back to the developer. It is timed before legal completion so issues are addressed before you take ownership.

Level 1 Home Survey

A Level 1 Home Survey is a condition survey suited to newer and conventional properties in good order. It highlights significant defects, risks and urgent issues. It is useful for a newer home that has already completed, or where you want an independent condition overview rather than a developer snagging list.

Which do you need?

Buying off-plan or before legal completion: a pre-completion snagging survey is usually the priority. An already-completed newer home where you want an independent condition check: a Level 1 Home Survey. Some buyers use a snagging survey at handover and a condition survey later — tell us your situation and timeline and we will advise.

Key takeaways

  • New-builds still benefit from an independent inspection.
  • Snagging survey: pre-completion, lists defects for the developer to fix.
  • Level 1: an independent condition overview of a newer property.
  • Timing relative to legal completion usually drives the choice.

Frequently asked questions

Is a snagging survey worth it on a new-build?

For most buyers, yes — identifying workmanship and finishing defects before legal completion means the developer is responsible for putting them right, and you have an independent, documented list.

When should a snagging survey be done?

Ideally before legal completion, so defects are recorded and addressed before you take ownership. We will work to your completion timeline.

Do I need a survey if the new-build has a warranty?

A structural warranty and an independent inspection serve different purposes. A snagging survey identifies workmanship and finishing issues at handover that you will want resolved regardless of longer-term structural cover.
