What Is a Snagging Survey?
A snagging survey is a professional inspection of a new build home that records defects and unfinished work so the builder can put them right. A qualified inspector checks over 200 points, from roof tiles to socket alignment, and produces a written report with photographs that you send to your builder.
Snags range from cosmetic faults — scuffed paintwork, misaligned tiles, poorly finished plaster — to problems that affect safety and running costs, such as gaps in insulation, fire doors that do not seal, or drainage that does not fall correctly. Many are hard for a buyer to spot. An inspector checks loft insulation, tests every window and door, looks behind bath panels and assesses external brickwork and pointing.
The report is your evidence. Under NHBC Buildmark and most other UK new home warranties, the builder must put right defects that breach the warranty standards and are reported in the first 2 years after legal completion. A dated, itemised report with photos makes those defects hard to dispute. Our guide to what snagging is covers the process in more detail.
Why Are New Build Complaints Rising in 2026?
Complaints about new homes more than tripled in a year. The New Homes Ombudsman Service received 1,802 formal complaints in 2025/26, up 204% from 593, and snagging enquiries rose 205%. Defects and snagging were the issues buyers raised most often, from poor plastering to missing cavity wall insulation.
Source: NHOS Annual Report 2025/26 (as reported by Property Industry Eye) · checked 20 October 2026Part of the rise reflects more developers joining the voluntary scheme, which now covers over 65% of UK new-home sales. But the Ombudsman's casework also shows how disputes escalate: the original defect is rarely the whole problem. Slow responses, poor communication and weak complaint handling turn manageable snags into long disputes. Homeowners won 82% of final decisions in 2025/26.
“Our casework shows that relatively manageable problems can become lengthy disputes when developers are too slow to respond or put things right.”
The practical lesson for buyers: a clear, professional record of every defect, submitted in writing and early, is what gives you leverage — first with the builder, then with the Ombudsman or your warranty provider if you need them.
Where are you in the process?
The right snagging survey depends on where you are in the buying process. Before completion, book a pre-completion inspection. In your first 9 months, a standard snagging survey catches issues that appear once you live in the home. Before month 24, a final inspection protects your 2-year builder warranty.

Top Snagging Inspectors in the UK
The top snagging inspectors on SnaggingFinder are ranked by an editorial score: the equal-weighted average of inspection quality, report detail, value for money, report speed and customer service. It is not a customer-review average. Each listing shows qualifications, published prices and the month we last checked them against the inspector's own website.
Inspectors cannot pay for a higher position. Our methodology publishes the formula and the inputs for every score, so you can check how any ranking was reached.

How Much Does a Snagging Survey Cost in the UK?
Published prices for the inspectors we list range from £249 to £475. Property size is the biggest driver: a 1–2 bed flat starts from £249–£350, a 3 bed house from £299–£400 and a 4 bed house from £349–£475. RICS-regulated firms and extras such as thermal imaging tend to cost more.
| Property size | Lowest listed price | Highest listed price |
|---|---|---|
| 1–2 bed flat | £249 | £350 |
| 3 bed house | £299 | £400 |
| 4 bed house | £349 | £475 |
Weigh the fee against what is at stake. Professional reports commonly record 40–150 items, and once the 2-year builder warranty period ends, NHBC Buildmark cover in years 3–10 is limited to structural defects. Workmanship faults you never reported become yours to pay for. The survey ROI calculator compares the fee with estimated repair costs for your property. Always confirm the current price with the inspector before booking.
Pre-Completion or Post-Completion: When Should You Book?
Book before completion if you can. A pre-completion inspection happens before you get the keys, when the builder has the most incentive to fix things and every room is empty. If you have already moved in, book a standard snagging survey within the first 9 months, and always before the 2-year warranty ends.
Developers registered with the New Homes Quality Board must offer buyers the chance to carry out a pre-completion inspection with a professional inspector, so ask your sales adviser for an inspection date as soon as completion is scheduled. A post-completion survey has its own advantage: after a few months of living in the home, problems with drainage, condensation and heating that were invisible at handover often show themselves.
An inspection around 18–24 months after completion is your last chance to report workmanship defects under the builder warranty. Read the guides to pre-completion inspections, post-completion snagging and the 2-year warranty.
How Do You Choose a Snagging Inspector?
Choose an inspector with a recognised qualification, professional indemnity insurance, a sample report you can read before booking and a clear price for your property size. RICS regulation, RPSA membership and CIOB accreditation each signal professional standards, but for most snagging jobs the quality of the report matters more than the badge.
- Qualification: confirm membership on the professional body's own register, not just the inspector's website.
- Insurance: ask for professional indemnity and public liability cover.
- Sample report: look for room-by-room photos and a precise location for every defect, in a format your builder can act on.
- Turnaround: listed inspectors state report times from 24 hours to 3 days — check this fits your completion date.
- Re-inspection: ask whether they will return to confirm the builder's repairs.
- Extras: thermal imaging can reveal insulation gaps and cold bridging that a visual check misses.
RICS regulation adds weight if a dispute may reach the Ombudsman or court. For straightforward snagging, experienced non-RICS inspectors are often just as thorough and cost less. You can compare inspectors side by side.
What Happens After You Get Your Snagging Report?
Send the full report to your builder's customer care team in writing, ask for a timetable for repairs and keep every reply. If the builder does not respond or fix covered defects, use its complaints process, then your warranty provider's resolution service or, if the developer is registered, the New Homes Ombudsman.
- Email the report and ask for written acknowledgement.
- Follow up after 4–6 weeks and log every date and response.
- Book a re-inspection once repairs are done to confirm they meet the standard.
- Escalate unresolved defects: the NHBC Resolution Service is free for homes with NHBC cover, and the New Homes Ombudsman handles complaints against registered developers.
“Our advice for customers is before you reserve, check the developer and the protection that comes with the home, and look for New Homes Quality Code and NHOS coverage. Then get important promises in writing, inspect the final build carefully and keep a clear record if anything needs fixing.”
Our builder disputes guide walks through each escalation step. It is general guidance, not legal advice.
Common New Build Snagging Issues
Snags in new build homes range from cosmetic finishing faults in paintwork, plaster, sealant and tiling to doors and windows that do not close or seal properly, poorly fitted loft insulation, drainage and gutter faults, and defects in external brickwork. Professional inspectors check over 200 points across every room and the exterior.
Not every snag is cosmetic. Cases brought to the New Homes Ombudsman in 2025/26 included missing cavity wall insulation, incorrectly installed fire safety equipment, defective party walls and acoustic problems — defects that are expensive to put right once warranty cover narrows.
Know Your Developer?
Your builder's HBF star rating shows how many of its buyers would recommend it to a friend — a customer satisfaction measure, not a defect rate. Even five-star builders hand over homes with snags, so check your developer's rating, warranty provider and New Homes Quality Board registration, then have the home inspected anyway.
“Customers are the ultimate judges of performance and so receiving such high scores based on their feedback alone is a significant achievement.”
That is why the ratings are worth reading, and why they are no substitute for an inspection: the HBF survey asks buyers about their experience around 8 weeks after moving in, before many defects show up. Our developer pages pair HBF data with the snags buyers commonly check for in each builder's homes.

Frequently Asked Questions
What is a snagging survey?
A snagging survey is a professional inspection of a new build property to identify defects and unfinished work. A qualified inspector checks over 200 points across the entire property — from roof tiles to socket alignment — and produces a written report with photographic evidence. Under NHBC Buildmark and most other new home warranties, defects that breach the warranty standards and are reported within the first 2 years are the builder's responsibility to put right.
How much does a snagging survey cost in the UK?
Published prices for the inspectors we list range from £249 to £475 depending on property size and the inspector's qualification. Published "from" prices are £249–£350 for a 1–2 bed flat, £299–£400 for a 3 bed house and £349–£475 for a 4 bed house. Always confirm the current price with the inspector before booking.
Do I need a snagging inspector?
In most cases, yes. In the HBF National New Homes Survey, 93.7% of responding buyers reported problems to their builder. Professional snagging reports commonly record 40–150 items, and covered defects reported within the 2-year builder warranty period are the builder's responsibility to put right. Published survey prices for listed inspectors range from £249 to £475.
When should I get a snagging survey done?
The best time for a snagging survey is before completion — before you receive your keys. This is called a pre-completion inspection. If you have already moved in, a standard snagging survey in the first 9 months is the most common approach. In all cases, you must report defects to your builder in writing within the first 2 years to be covered by the defects liability period.
What is the difference between RICS and non-RICS snagging inspectors?
RICS (Royal Institution of Chartered Surveyors) is the UK's most prestigious property qualification. RICS-regulated inspectors are chartered surveyors with professional indemnity insurance and are subject to professional standards. Non-RICS inspectors (such as RPSA or CIOB members, or experienced ex-site managers) are often highly effective and more affordable. For straightforward snagging, both can be excellent choices. For high-value properties or legal disputes, RICS provides extra credibility.
What can I do if my builder will not fix snagging defects?
Put the full defect list in writing to the builder's customer care team and complete their internal complaints process. If that fails, escalate to your warranty provider — the NHBC Resolution Service is free for homes with NHBC Buildmark cover — or, if your developer is registered, to the New Homes Ombudsman Service. Homeowners won 82% of the Ombudsman's final decisions in 2025/26.
