A professional snagging inspector carries out a thorough, independent inspection of a new-build property before or after legal completion — finding defects that the developer's own sign-off process misses. Here's what they do, what it costs, and whether it's worth the fee.
Key Points
A professional snagger is an independent inspector who checks your new-build for defects before or after you move in
Typical cost: £300–£600 for a standard 3-bedroom new-build; larger homes cost more
The average professional snagger finds 100–150 defects per property — far more than most buyers spot themselves
Developers are legally obliged to fix snags within a 2-year warranty period (NHBC Buildmark or equivalent)
Ideally booked before legal completion — or within the first few weeks after moving in
Not RICS-regulated, but reputable snaggers are members of the New Homes Quality Board (NHQB) or RPSA
What Is a Professional Snagger?
A professional snagging inspector (or "professional snagger") is a specialist who carries out a systematic, room-by-room inspection of a newly built property to identify cosmetic defects, workmanship issues, and structural problems that the developer should fix before or after you move in.
Unlike a standard RICS survey — which assesses an existing property's structural condition — a snagging inspection is focused specifically on new-build quality and compliance with building regulations. The inspector produces a written snagging report that you submit to the developer, who is then obliged to carry out remedial work.
What Does a Professional Snagger Check?
🔨 Build Quality
Plasterwork — gaps, cracks, uneven surfaces
Paintwork — runs, missed patches, poor coverage
Skirting boards, architraves, and coving — gaps, poor joints
Doors and windows — operation, seals, locks
Floor coverings — lifting edges, poor joins
Tiling — chipped, uneven, poorly grouted
⚡ Services & Fittings
Electrical sockets and switches — level, operational
Plumbing — leaks, pressure, drainage
Heating — boiler operation, radiator balance
Kitchen units — alignment, handles, soft-close
Bathroom suites — sealing, fixtures, water flow
Ventilation — extractors, trickle vents
🏗️ Structure & Fabric
Roof — visible from windows / loft hatch where accessible
External walls — pointing, cracks, render finish
Guttering and drainage
Damp-proof course installation
Insulation in loft (where accessible)
Cavity closers and fire stops
📋 Compliance

When Should You Book a Professional Snagger?
✅ Best: Before Legal Completion
Book your snagger as soon as the developer gives you a completion date. Ask the developer to allow a snagging inspection in the days leading up to completion. This is the ideal window — defects can be noted and agreed before you legally take ownership, giving you the strongest leverage.
⚠️ Good: Within the First 4 Weeks After Completion
If the developer didn't allow pre-completion access, book immediately after moving in. Most snags are most visible before furniture is in place. You remain within the 2-year warranty period for all defects found.
❌ Avoid: After the 2-Year Warranty Expires
After 2 years you lose the right to demand the developer fixes defects. Structural issues are covered for 10 years under NHBC Buildmark, but cosmetic and workmanship defects must be reported within the first 2 years.
Is Hiring a Professional Snagger Worth It?
💡 In short: almost always yes. Professional snaggers consistently identify defects that buyers miss — at an average of 100–150 per property. Many of these defects would cost significantly more to fix after the warranty period expires than the £300–£600 inspection fee.
✅ Pros
Trained eye — spots defects untrained buyers miss
Produces a formal, written report developers take seriously
Potentially saves thousands in post-warranty repair costs
Gives you leverage to delay completion if serious issues found
Objective — no emotional attachment to the property
Usually completes within 1–2 weeks of booking
❌ Cons
Additional upfront cost of £300–£600
Not RICS-regulated — quality varies between inspectors
Developer may delay access before completion
Report doesn't guarantee developer will act quickly
Doesn't cover structural defects (NHBC covers these separately)
How to Choose a Reputable Professional Snagger
Since snagging is not RICS-regulated, it's important to vet your inspector carefully:
RPSA membership: The Residential Property Surveyors Association accredits specialist new-build inspectors
NHQB recognition: The New Homes Quality Board is the industry body for new-build standards
Previous experience: Ask which developers they have experience with and how many inspections they complete per year
Sample reports: Request an example report to check its depth and usability
Thermal imaging: Some snaggers use thermal cameras to detect hidden cold bridges and insulation deficiencies — worth paying for
Reviews: Check Google, Trustpilot, and Facebook for recent customer feedback specific to your development area
Frequently Asked Questions
Can I do my own snagging instead of hiring a professional?
Yes — and you should also do your own inspection. But studies consistently show that untrained buyers miss the majority of defects. A professional snagger's report also carries more weight with the developer's customer care team than a handwritten list. For a £300,000+ purchase, the £400 fee is almost always justified.
Can the developer refuse to let a professional snagger access the property?
Before completion, legally yes — the property is still the developer's. However, under the New Homes Quality Code (2022), developers committed to the Code must allow buyers reasonable access for a pre-completion inspection. After completion, access is entirely your right as the owner.
What happens after the snagging report is submitted to the developer?
The developer's customer care team reviews the report and schedules remedial work. Under NHBC warranty rules, emergency defects must be addressed within 24 hours; urgent defects within 5–7 days; non-urgent defects typically within 30 days. Keep copies of all correspondence in case you need to escalate to the NHBC or the New Homes Ombudsman.
Is a professional snagging inspection the same as a Level 2 survey?
No — they are quite different. A RICS Level 2 survey assesses the structural condition of an existing property and highlights defects relevant to a purchase decision. A snagging inspection assesses new-build quality and workmanship against build specifications and regulations. You would not typically commission both for the same new-build property.
