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
According to the Home Builders Federation 2025 National New Homes Survey, 93.7% of new build buyers reported a problem with their property after moving in. The average professional snagging survey finds between 40 and 150 separate defects.
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
For the first 2 years after completion, your builder is legally obligated to fix defects in your property at no cost to you. This is known as the defects liability 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.
