New Build Snagging Survey: What's Covered & Who Pays

Quick Answer: A new-build snagging survey is a professional defect inspection conducted within the first 2 years of purchase (NHBC warranty period) to identify defects the developer must remedy. Typical cost £300–£600. Best timed: pre-completion, pre-2-year warranty expiry, or after handover. Covers cosmetic, functional, and Building Regulations compliance issues against NHBC Standards 2020+, Building Regs current edition, and developer's marketing specifications.

Summary

New-build housing in the UK is built fast and inspected sparingly. The NHBC, Premier Guarantee, LABC and ICW warranty schemes provide 10-year structural cover but only meaningfully enforce defects in the first 2 years (the "defects period") and only if reported in writing. A snagging survey turns vague homeowner complaints into a structured defect list developers must address.

The trade opportunity is twofold: providing the survey itself (£300–£600 typical) or undertaking the remedial work the survey identifies. Many new-build defects are minor cosmetic (paint touch-ups, door alignment, sealant gaps) but tradesman-led surveys often catch more substantial issues — wrong cable spec, missing fire stopping, plumbing not to manufacturer detail, Building Regulations non-compliance.

This guide covers when to commission, what's included, the NHBC defects framework, what to do if the developer refuses to fix, and how tradespeople can offer snagging as a billable service.

Detailed Guidance

When to commission the survey

Pre-completion (best timing if developer permits):

Post-completion, within 6–8 weeks:

At 22–23 months (pre-2-year cutoff):

Many homeowners commission at multiple stages. The defects period is your one chance to extract free fixes.

What the survey covers

A thorough snagging survey examines:

External:

Internal — every room:

Kitchen:

Bathrooms:

Loft and services:

Building Regulations spot checks:

NHBC Standards as the benchmark

NHBC Standards 2025 set defined acceptability criteria for many defects. For example:

For complaints to stand up, refer to specific NHBC clause. "It doesn't look right" is rejected; "exceeds NHBC Standards 2025 Section X tolerance for wall plumbness" is acted on.

Building Regulations compliance — the developer's blind spot

Many developer defects are Building Regs non-compliance, not just cosmetic:

If you find Building Regs non-compliance, the developer must fix — and Building Control can be brought in if refused. This is the highest-leverage finding in any snagging report.

Tradesperson-led snagging — selling the service

Tradespeople have an advantage over generalist snaggers — depth of trade knowledge. Position your service:

Electrician-led survey — Find the wrong cable sizes, missing earth bonding, incorrect circuit protection, unlabelled consumer unit. Charge £400–£600 for snag + write-up.

Plumber-led survey — Find pressure issues, inadequate isolation valves, incorrect waste falls, missing trap seals, wrong pipe materials. Charge £400–£600.

General builder/quantity surveyor-led — Most comprehensive, broad coverage. Charge £350–£550.

For higher-margin work, offer "snag + remedial quote" — snag the property, then quote on items developer refuses to fix (often <£500 cosmetic items the homeowner just wants done). Margin on remedial work compensates for moderate survey fee.

Reporting standards

A useful snagging report includes:

Standard format: PDF report with photo-rich entries, room-by-room layout. 20–40 pages typical for 3-bed home.

What if the developer refuses to fix?

Escalation route:

  1. Written request to developer — Snagging list referenced, reasonable deadline (typically 28 days)
  2. Written complaint to developer's customer care manager — 28-day response window
  3. Warranty provider complaint (NHBC, Premier Guarantee, LABC) — Provider mediates between buyer and developer
  4. Consumer Code for Home Builders — Independent arbitration service if developer signed up
  5. Building Control / Local Authority — If Building Regs breach
  6. Small claims court — Where defects breach Sale of Goods Act / consumer rights

In practice, snagging-list items presented in writing with photos and NHBC references are usually addressed within 2–6 months. The defects period gives buyers leverage; use it.

Worked example — 4-bed new build snag survey

For combined snag + remedial quote, add £150–£400 to the survey fee depending on scope.

Frequently Asked Questions

Is a snagging survey worth £400 if my new home looks fine?

A new-build typically has 80–200 minor defects, most invisible to untrained eyes. The developer's "defects period" is your one chance to get them fixed for free. £400 to extract £2,000+ of remedial work is excellent value. Most homeowners who don't snag pay later when they discover issues themselves and the warranty has expired.

Can I do the survey myself with a checklist?

Yes — and it's worth doing as a starting point. But trade-trained eyes catch issues homeowners miss: incorrect cable sizes, missing fire stopping, plumbing falls, Building Regs non-compliance. Trade-led surveys typically find 30–50% more chargeable defects than DIY checklists.

What's the difference between NHBC and warranty?

NHBC is one of several warranty providers (others: Premier Guarantee, LABC Warranty, ICW). All provide 10-year structural cover but differ in defect coverage and dispute resolution. NHBC is most common (~80% of UK new-builds). Check which warranty your home has.

Will the developer pay for the survey?

No. Developer pays for fixing defects, not the inspection. Some homeowners try to bill the developer for the survey — universally refused. Build the cost into your "moving in" budget.

What if I'm already past the 2-year defects period?

Limited options. Cosmetic and minor functional issues become your problem to fix. Structural defects (subsidence, major cracks, roof leaks) remain warranty-covered to year 10 — but the threshold is high. Some warranty schemes also include a 7-year "structural" period for non-major items.
