Buying a new build property is exciting — but the industry’s own data shows that the average new build has over 100 defects at the point of legal completion. A professional snagging survey is the most effective way to ensure your developer fixes every defect before you move in.
What Is a Snagging Survey?
A snagging survey is a professional inspection of a new build property that identifies all defects — from cosmetic issues like scratched surfaces and poorly fitted units to structural, electrical and plumbing problems that need rectification. The inspector produces a detailed photographic report that you submit to your developer, who is legally required to fix defects under your warranty.
What Does a Snagging Survey Cover?
A comprehensive snagging survey covers every accessible element of the property:
External inspection: roof covering and ridge tiles, gutters and downpipes, brickwork and mortar pointing, window and door frames, thresholds and drainage, paving and landscaping, garages and outbuildings.
Internal — structure and fabric: walls and ceilings (cracks, poor plastering, staining), floors (squeaking, unevenness, damage), doors and windows (fitting, locking, sealing), loft space (insulation, structure, party wall fire stopping).
Mechanical and electrical: heating system and controls, hot water cylinder and pressure, electrical consumer unit and circuits, socket and switch alignment, ventilation (kitchen and bathroom extraction), smoke and carbon monoxide detectors.
Kitchen and bathrooms: unit fitting and alignment, worktop joints and sealing, tiling (alignment, grouting, adhesion), sanitary ware (fitting, sealing, operation), shower trays and enclosures.
How Many Defects Should I Expect?
Industry research from NHBC and consumer groups consistently shows an average of 100–160 defects per new build property at completion. Even from reputable major developers, snagging lists of 50+ items are common. Most are minor cosmetic issues, but structural, drainage, and fire safety defects are found in a significant minority of surveys and must be taken seriously.
When Should I Book?
Ideally before legal completion — you have the right to inspect a property you are about to purchase. Some developers resist this, but you are entitled to access. If you cannot get pre-completion access, book your snagging survey immediately after receiving the keys, before you start decorating or making changes that could complicate defect attribution.
What Happens With the Report?
Submit the snagging report to your developer’s customer care team in writing. Under your NHBC Buildmark warranty (or equivalent), the developer must rectify defects reported within the first two years. Track responses, chase up unresolved items, and escalate to the warranty provider or the New Homes Ombudsman if the developer fails to act.
