New Build Snagging Survey: What's Covered and Who Arranges It

Quick Answer: A new build snagging survey is a buyer-commissioned inspection of a new home, typically done in the 3–14 days before legal completion or within the first 6 months. It identifies builder defects (cosmetic, functional, regulatory) so they can be rectified under the warranty. UK cost £250–£600 for a typical 3-bed property. Distinct from the NHBC or builder warranty inspection — the snagging surveyor is independent and reports to the buyer.

Summary

UK new builds — even from the largest housebuilders — routinely complete with 50–250 minor defects. Snagging surveys exist because most buyers don't have the experience to spot issues that will become problems within 12–24 months: hairline cracks in plasterwork, doors not catching, switches wired the wrong way round, render with hollow patches, missing trickle vents, badly bedded drainage. The builder is contractually obliged to rectify these under their warranty (NHBC, LABC or similar), but only if reported within the warranty period.

In 2026, snagging is now a recognised home-buying step. The Home Builders Federation (HBF) and Consumer Code for Home Builders both encourage independent snagging surveys, and most major housebuilders accept the snagging report as the basis for warranty claim resolution. The market has matured — typical surveyors are RPSA, RICS or specialist new-build inspectors with 5–20 years' experience.

Key Facts

• Survey cost (2026) — £250–£500 for typical 3-bed semi; £400–£700 for 4–5 bed detached; +£100–£200 for executive home
• Survey duration — 2–4 hours on site for typical home; comprehensive surveys 5–8 hours
• Number of items typically found — 50–250 in a typical new build
• NHBC warranty period — 10 years total, with builder responsibility for years 1–2
• Builder warranty period — 24 months for most defects
• Pre-completion snagging — increasingly available; some builders allow access 3–14 days before completion
• 6-month list — many builders accept a "6-month list" of issues; consolidated report at the 6-month point
• Final NHBC inspection — at end of year 2; major issues for builder, after which NHBC takes over
• Common items — paintwork, plaster cracks, door alignment, wiring, plumbing, drainage, roof, render
• Items rarely on first survey — structural issues (timer-related, including tile creep, settling cracks)
• Latent defect period — 6 years for contract claims; 10 years for NHBC warranty

Detailed Guidance

When to commission

Three windows for snagging:

1. Pre-completion snagging (3–14 days before legal completion) — best timing. Issues identified before completion can be rectified before move-in. Some builders offer this; others restrict pre-completion access. Cost: £350–£600.
2. First-month snagging (within 1 month of completion) — most common timing. Buyer can move in, settle, then arrange survey to identify issues. Cost: £250–£500.
3. Six-month review — many builders accept a consolidated 6-month list. Buyer keeps a list of issues during first 6 months, then arranges surveyor to compile it. Cost: £250–£500.

For most buyers, a pre-completion snagging is most cost-effective, but a first-month survey is the realistic norm.

What the surveyor checks

A typical snagging survey covers:

External:

• Roof (tile alignment, lead detail, pointing on chimneys, verge details)
• Windows and doors (sealing, alignment, opening, security)
• Render and external walls (hollows, cracks, drips, weather staining)
• Gutters and rainwater pipes (alignment, fittings, fall)
• Soffit, fascia and barge boards (alignment, painting, fixing)
• External drainage (gullies, manholes, soakaway access)
• Path and paving (levelling, edge detail, compaction)
• Garden walls and fencing
• Garage doors and access
• Driveway and off-street parking

Internal:

• Plasterwork (every wall, every ceiling — cracks, hollows, finish)
• Decoration (paint coverage, drips, runs, missed areas)
• Doors (alignment, closing, hinges, locks, handles, frame seal)
• Skirting and architrave (mitre cuts, fixing, paint)
• Floor coverings (alignment, joins, edges, finish)
• Stairs (treads, balustrading, handrail, paintwork)
• Kitchens (worktop, joints, units, drawers, hinges, sealant, appliances)
• Bathrooms (tiling, grout, sealant, taps, drainage, vents)
• Heating (radiators, controls, boiler operation, balance)
• Electrical (sockets, switches, ceiling roses, lighting)
• Ventilation (extracts working, trickle vents installed, MVHR if specified)
• Loft (insulation, eaves access, hatch, vents)

A typical 3-bed survey produces 50–150 line items. Snagging reports have grown more detailed in recent years — 200+ item reports are common from premium surveyors.

What the surveyor does NOT typically check

• Specialist appliances — boilers, MVHR units (covered by manufacturer warranty)
• Gas safety (separate Gas Safe inspection)
• Building Regulations compliance (covered by Building Control sign-off)
• Structural performance (covered by builder warranty)
• Future weather performance (limited in a single inspection)

For specialist concerns (e.g. gas safety, structural), commission separate specialist surveys.

How issues are rectified

Once the report is delivered:

1. Buyer submits list to builder — usually via the builder's customer-care portal
2. Builder schedules rectification — typically 4–12 week timescale for most items
3. Tradesperson visits — sometimes the original sub-contractor returns; sometimes a different contractor
4. Buyer signs off when satisfied — keep a copy of the original list and rectification status

Common builder responses to snagging items:

• Cosmetic plasterwork — rectified within first 6 months by builder's decoration team
• Joinery — rectified by builder's carpentry team
• Plumbing — typically scheduled across multiple homes in the same development to share visit costs
• Roofing — rectified by external specialist once the development is more complete
• Render — sometimes deferred to year 1 to allow drying and natural movement before remediation

Difficult-to-resolve issues

Some items take longer or escalate:

• Render cracks — builder may delay remediation expecting natural settling
• Foundation movement — escalates to NHBC investigation; can take 12–18 months
• Structural issues — full structural engineering investigation
• Drainage failure — may require excavation and re-laying

Always escalate to NHBC (or relevant warranty provider) if builder is unresponsive after 30 days. The NHBC has its own dispute resolution process.

Frequently Asked Questions

Should I commission a snagging survey on a £250,000 new build?

Yes. The £250–£500 cost is small relative to the value of the property and the cost of repairs that go un-noticed. Most surveys identify £2,000–£8,000 of work that the builder is contractually obliged to do — getting these on the warranty list is essential.

Can the builder refuse the snagging surveyor?

Some builders restrict pre-completion access. After completion, the home is the buyer's, and any surveyor with appropriate insurance can visit. The builder cannot refuse access to a buyer-commissioned inspection on a completed home.

What if the builder doesn't fix the issues?

Escalate to the relevant warranty provider (NHBC, LABC, Premier, Build-Zone, etc.). Most warranty providers have a formal complaints procedure that escalates to a dispute panel. The Consumer Code for Home Builders also has a third-party dispute resolution process. Persistent failure can lead to enforcement action by the local Building Control authority.

How quickly does the builder need to fix items?

Most items: 4–12 weeks from report delivery. Defects affecting habitability (e.g. heating not working, water leak) should be addressed within days. The Consumer Code for Home Builders requires builders to respond to defect reports within 14 days and provide a rectification timeline.

How much does a snagging survey cost (homeowner-friendly)?

For a typical UK new build 3-bed semi, a professional snagging survey costs £250–£450 in 2026. For a 4–5 bed detached, £400–£700. Premium surveys with comprehensive reports (200+ items, photographs, recommendations) £500–£900. Most companies don't charge VAT for residential surveys. The cost is minimal vs the value identified — most surveys produce defect lists that, if the buyer had to commission private contractors to fix, would cost £3,000–£10,000.
