York Surveyors carries out snagging surveys on new build homes across York and North Yorkshire every week — and the results are consistently eye-opening. The average new build home in the UK has over 150 defects at the point of legal completion. Many of these are cosmetic, but a significant proportion are structural or building-regulation issues that the developer is legally obliged to fix. Here's everything you need to know.
What Is a New Build Snagging Survey?
A snagging survey is a detailed inspection of a newly built home, carried out by an independent professional surveyor, to identify defects and incomplete works before or immediately after you move in. The term "snagging" refers to the process of identifying items that need to be rectified — and creating a formal list (a "snagging list") to present to the developer.
Unlike a standard building survey on an older property, a snagging survey is specifically focused on the quality of workmanship and the completeness of construction. Rather than looking for historic defects, we're checking whether the new build has been constructed to the standard required by building regulations, NHBC Buildmark warranty requirements, and the developer's own specification.
Why Can't I Just Do the Snagging Myself?
Many new build buyers walk round their new home before completion, make a few notes about a scuff on a wall or a door that doesn't close properly, and think they've done a thorough job. They haven't — and it's not their fault. Identifying the full range of defects in a new build requires professional training, specialist equipment, and a systematic approach that most homeowners simply don't have.
Our surveyors check dozens of areas that buyers typically miss entirely: roof structure and ventilation, drainage falls, electrical socket alignment, fire stopping, insulation continuity, cavity trays, damp proof courses, structural ties, and much more. We use moisture meters, spirit levels, and thermal imaging to detect issues that are invisible to the naked eye.
Moreover, having an independent surveyor's report gives you far stronger grounds for requiring the developer to rectify issues. A developer is unlikely to take a buyer's handwritten list very seriously; a professional report from a RICS-accredited surveyor is much harder to dismiss.
Common Defects Found in New Build Homes in York
Based on our snagging surveys across York's new build developments — including properties in Derwenthorpe, Poppleton Bar, Monks Cross and beyond — here are the most common categories of defect we find:
Structural and Building Envelope
- Inadequate cavity wall insulation — gaps, voids, or compressed insulation that reduces thermal performance
- Missing or incorrectly installed cavity trays and weep holes above openings
- Poor pointing and mortar joints in brickwork
- Inadequate roof ventilation at eaves and ridge
- Incorrectly positioned damp proof courses
- Settlement cracks in block work partitions — often visible within weeks of construction
Internal Finishes
- Poor plasterwork — uneven surfaces, cracking around window and door openings, nail pops
- Misaligned skirting boards, architraves, and door frames
- Poorly fitted kitchen units — unlevel doors, misaligned hinges, gaps between units and walls
- Incomplete or poorly executed decoration — paint misses, drips, and contamination
- Doors that stick, bind, or fail to latch correctly
Mechanical and Electrical
- Electrical sockets and switches not level or not flush to wall
- Inadequate silicone sealing around baths, showers, and basins
- Boiler commissioning not completed or documented
- Missing or incorrectly positioned smoke and heat detectors
- Pipework not properly secured or insulated in roof voids
External Areas
- Driveways and paths with ponding water due to incorrect falls
- Boundary fencing incomplete, incorrectly positioned, or not to specification
- Landscaping not completed or to specification
- External lighting not operational
- Garage doors misaligned or not sealing correctly
When Should You Have a Snagging Survey Done?
The best time to have a snagging survey is before legal completion — ideally within the two-week period before you exchange contracts and take ownership. This gives you the clearest leverage: the developer needs to complete the sale and is most motivated to rectify items quickly.
If the developer won't allow access before completion, have the survey done within the first two weeks of moving in. The NHBC Buildmark warranty places an obligation on the developer to fix defects notified within the first two years, so the sooner you act, the better.
⚠️ Important
Some developers may tell you that they conduct their own "quality control inspections" and that an independent snagging survey is unnecessary. This is a conflict of interest. Always commission your own independent inspection. The cost is modest compared with the value of the property and the potential cost of remedial works.
What Happens After the Snagging Survey?
Once we've completed the inspection, we produce a detailed written report — typically within three to five working days — listing every defect identified, with photographs and clear descriptions. We categorise items by severity and indicate which are urgent, which relate to building regulations, and which are cosmetic.
You then present this report formally to the developer's customer care team. Developers are required under the Consumer Code for Home Builders and the NHBC Buildmark warranty to rectify genuine defects within a reasonable timescale. If you have difficulty getting the developer to respond, our report can be used to support a formal complaint to the NHBC or the New Homes Ombudsman.

Frequently Asked Questions About New Build Snagging in York
Yes. A snagging survey is most effective before completion, but it can still be carried out after you've moved in. Under the NHBC Buildmark warranty, the developer is responsible for fixing defects notified in the first two years. We recommend acting as quickly as possible — ideally within the first three months of moving in.
Some developers do restrict access before completion, which is their legal right. However, the Consumer Code for Home Builders encourages transparency and fairness, and many developers will allow access once the property is complete and ready for handover. Even if access is refused before completion, a survey carried out immediately after you move in is still highly valuable within the two-year NHBC period.
For most brand-new homes, a snagging survey alone is appropriate. If you are buying a new build that is being converted from an older structure — for example, a barn conversion or a converted commercial building — a more detailed RICS Level 3 Building Survey may be advisable in addition to the snagging inspection.
The NHBC Buildmark warranty is a 10-year warranty provided by the developer through the National House Building Council. In years one and two, the developer is responsible for fixing defects. In years three to ten, the NHBC provides insurance cover against major structural defects. Having a professional snagging report ensures you can clearly identify and evidence defects that fall within the developer's obligations in the first two years.
