Do you need a snagging survey on a new-build home?

Is a snagging survey a RICS Level 2 or Level 3?

Not unless the person doing it is instructed to produce one. RICS publishes Level 1, Level 2 (survey only), Level 2 (survey and valuation) and Level 3. Snagging is a word the market uses for a close look at a new or newly converted home, often focused on finishes. If you want the traffic-light ratings and the limits written into the Home Survey Standard, say which level you are buying.

A developer walking the plot with you is not independent, and an independent snagging firm is not automatically RICS-regulated. Ask who they are. The RICS consumer guide explains why regulation matters. It does not ban anyone else from making a list.

What does NHBC say the ten years are for?

On its homeowner pages, reviewed for this guide on 24 October 2026, NHBC describes Buildmark as 10-year warranty and insurance for newly built or newly converted homes. Before completion there is insolvency cover for the first owner. For about two years after the start date on the certificate, the builder is responsible for defects that are a breach of NHBC requirements, and NHBC describes a resolution service behind that. For the following years, NHBC describes insurance for physical damage caused by a failure to build specified parts to its requirements.

That is a summary of NHBC’s own description, not a promise about your plot. The policy has exclusions, a minimum claim value, and a certificate. If your home is covered by a different warranty body, none of those periods transfer across.

Should you inspect before legal completion?

If you wait until you have completed, you own the problem of chasing the builder from inside the house. If you look before completion, you can still ask for items to be finished, and you can still decide the home is not what you agreed, subject to the contract you signed. Reservation agreements and exchange do not all work the same way. Your solicitor tells you which point is the point of no return. This guide does not.

A survey booked for the week of completion is only useful if the report will exist before you are committed. Ask the surveyor for the date of the report, not the date of the visit.

Which new-build comments are finishes, and which are fabric?

Scratches, missed mastic, decorating and a door that binds are finishing items. They can matter to you and still be ordinary builder’s work. Movement cracking, a floor that ponds, gutters that discharge into the wall, or a roof space with missing restraint are fabric. A home survey is there for the second list. A snagging list can hold both, as long as you do not price them as if they were the same job.

New homes crack as materials dry. A crack is still a symptom. The surveyor, if you appoint one, should say whether they think it is drying-out or something to investigate. Do not let a forum name the cause.

How to snag a new-build home

A practical order of work for a buyer in England or Wales. It is not a claim that every new home is defective, and it does not replace the warranty wording.

1. Read the warranty you were actually offered. Ask which policy applies, and for which address. NHBC Buildmark is one product. Other warranty bodies exist. Do not argue with a builder using a different company’s cover periods.
2. Walk the home slowly, with the lights on. Look at finishes, doors, glazing, gutters, loft hatches and outside levels. Write down what you can see. A list of cosmetic items is not a structural opinion.
3. Separate snags from anything that might be structural. Stuck doors and scratched worktops are for the builder’s finishing list. Cracks that worry you, damp, or drains that do not run are a reason to ask a surveyor or a relevant specialist, not a reason to invent a cause.
4. Decide whether you want a RICS Home Survey as well. Level 2 or Level 3 is a condition report under the Home Survey Standard. It is optional. A developer’s quality inspection is not that product, even if someone calls it a survey.
5. Report defects in writing inside the warranty period. NHBC says that during the builder warranty period, usually the first two years from the date on the policy certificate, you contact the builder and keep a record. The later insurance section is not the same as that first period. Use the dates on your certificate, not a date from a forum.
6. Do not treat a reservation fee as a survey. Reservation agreements differ. Whether a fee is refundable if you withdraw after a survey is in that agreement. Read it, or ask your solicitor to, before you rely on a general rule.
