What is Snagging? A Complete Guide for New Build Buyers
Snagging is the process of identifying defects and unfinished work in a new build property so that the builder can fix them before or after you move in.
The UK's New Build Problem
In the Home Builders Federation National New Homes Survey (as cited from HBF's March 2025 publication), 93.7% of responding new build buyers reported problems to their builder. Professional snagging reports commonly record somewhere between 40 and 150 items, depending on the property (an editorial range, not a survey statistic).
These defects range from minor cosmetic issues (scuffed paintwork, misaligned cabinet doors) to more significant problems (drainage failures, fire door seals, insulation gaps).
Your 2-Year Builder Warranty
Under NHBC Buildmark and most other UK new home warranties, the builder is responsible for putting right defects that breach the warranty standards and are reported within the first 2 years after legal completion, at no cost to you. This is usually called the builder warranty or defects period.
After 2 years, only structural defects are covered under your NHBC Buildmark warranty (years 3-10). This means identifying and reporting defects within 2 years is critical.
DIY vs Professional Snagging
You can conduct your own snagging inspection using a checklist. However, professional snagging inspectors typically find 3-5 times more defects than a homeowner inspection because they know exactly where builders cut corners and what problems look like at an early stage.
A professional written report also carries significantly more weight with builders than an informal list from the homeowner.
Types of Snagging Survey
- Pre-Completion Inspection: Conducted before you receive your keys. This is the most effective time as the builder has maximum motivation to resolve issues before completion.
- Standard Snagging Survey: Conducted in the first 9 months after moving in. The most common type. Covers all visible defects throughout the property.
- Fundamentals Survey: For homes 9-18 months old. Focuses on structural, service, and weather-related defects that may have emerged since moving in.
- Pre-Warranty Expiry Survey: Conducted in the final months before your 2-year warranty expires. Last chance to report defects under the defects liability period.
Frequently Asked Questions
What is snagging in a new build?
Snagging is the process of identifying defects and unfinished work in a newly built property. It ranges from minor cosmetic issues (scuffed paint, misaligned doors) to significant problems (drainage failures, fire door seals). A professional inspector produces a written snagging list that your builder must address under the 2-year defects liability period.
How long do you have to snag a new build?
You have 2 years from the date of legal completion to report defects to your builder under the defects liability period. Defects reported after 2 years are only covered if they are structural (years 3–10 under NHBC Buildmark). It is strongly recommended to conduct a professional snagging survey in the first 9 months — before any defects become harder to prove.
Can I snag my own new build?
Yes, you can snag your own property using a checklist. However, professional inspectors typically find 3–5 times more defects than a homeowner, because they know exactly where builders cut corners. A professional written report also carries more weight with builders. For a free starting point, download our 200-point snagging checklist.
Is my builder legally required to fix snagging defects?
In most cases, yes, but the obligation comes from your new home warranty and purchase contract rather than a single law. Under NHBC Buildmark and most other UK new home warranties, the builder is responsible for putting right defects that breach the warranty standards and are reported within the first 2 years after legal completion, at no cost to you. Notify the builder in writing. Wear and tear, normal shrinkage and damage you cause are typically excluded. If the builder does not act, you can use your warranty provider's resolution service (for example NHBC) or, if the builder is registered with the New Homes Quality Board, the New Homes Ombudsman Service. This is general guidance, not legal advice.
What is the difference between snagging and a structural survey?
A snagging survey focuses on workmanship defects and unfinished items in a new build — the kind of issues builders create during rapid construction. A structural survey (Level 3 Building Survey) is a comprehensive assessment of an older property's structural integrity. New build buyers need a snagging survey; buyers of older homes typically need a structural survey.
