A snagging survey is an independent inspection of a new-build property that identifies defects (“snags”) the developer should fix before they become your problem. It covers everything from poor finish quality and badly fitted fixtures to plumbing, electrical and external defects, producing a written snag list that can be sent to the developer for remediation. The best time to book one is just before completion, or within the 2-year period when the developer remains responsible for defects under the new-build warranty.
Most new-build properties contain dozens of snags, often a hundred or more on larger homes. Developers move quickly to meet completion targets and rely on buyers to identify issues themselves. An independent snagging survey gives you a complete list and the leverage to get them fixed properly.

What a snagging survey checks
A snagging survey is more thorough than a quick walk-around, covering every room, every external elevation, and every system in the property.
Finish quality
- Paintwork (drips, missed areas, poor coverage)
- Plaster (cracks, uneven surfaces, bumps)
- Tiling (grout lines, uneven cuts, hollow tiles)
- Skirting, architrave and trim
- Door alignment and operation
- Window operation and seals
Fixtures and fittings
- Kitchen units, doors, drawers, worktops
- Bathroom fittings, taps, shower screens
- Wardrobes and built-in storage
- Handles, hinges, catches
Plumbing
- Taps and waste fittings
- Shower function and seals
- Toilet operation
- Visible pipework
Electrical
- Sockets and switches (correct fitting, function)
- Light fittings
- Fuse board, smoke alarms, CO alarms
External
- Brickwork, render, mortar joints
- Roof from ground level (missing tiles, mortar)
- Gutters and downpipes
- External doors, windows, seals
- Driveways, paths, patios
- Boundary fencing
- Garden landscaping
Documentation and compliance
- Confirming the property matches the agreed plans and specification
- Highlighting anything that doesn’t meet new-build standards
Why developers don’t catch all the defects
Three factors drive the volume of snags in new-build homes.
Speed of build
Developers work to tight schedules. Each trade comes through quickly, often with the next trade starting before the previous one has fully finished. Small issues at one stage compound through the next.
Cost pressure
Margins on new-build homes are managed tightly. Fixing defects costs money, and a defect not identified by the buyer often doesn’t get fixed.
Internal inspections aren’t independent
Most developers have their own quality inspectors, but they work for the developer. An independent snagging surveyor works for you, with no incentive to overlook issues.
When to book a snagging survey
There are three windows where a snagging survey adds real value.
1. Pre-completion (best timing)
Before you legally complete on the property, the developer has the strongest incentive to fix defects (they need your money). Booking a snagging survey 2 to 3 weeks before completion gives them time to remediate before you move in.
2. Within the first 2 years (warranty period)
New-build homes come with a 2-year defects warranty from the developer (and typically a 10-year structural warranty from a body like NHBC or LABC). Within the first 2 years, the developer is responsible for fixing defects. A snagging survey in months 1 to 18 gives you a comprehensive list to submit before the window closes.
3. End of year 2 (just before warranty expires)
A final snagging survey just before the 2-year mark catches anything that’s emerged with use, giving the developer one last chance to fix issues at no cost to you.
What happens after the survey
Once you have the snag list, the process is:
- Submit to the developer. Email the full report to the developer’s customer care team.
- Agree a remediation schedule. Most developers will arrange access dates to fix the snags.
- Inspect the remediation. Once works are complete, verify the fixes have actually resolved the issues.
- Escalate if needed. If the developer fails to fix items within reasonable time, escalate to the warranty provider (NHBC, LABC, Premier Guarantee).

Snagging survey vs Level 2 home survey
These are different products for different purposes.
| Feature | Snagging Survey | Level 2 Home Survey |
| Purpose | Identify defects in new-build for developer remediation | Assess condition for buyer making a purchase decision |
| Property type | New-build only | Any property |
| Inspection focus | Finish quality, fittings, compliance with specification | Structural condition, services, defects |
| Output | Itemised snag list with photographs | Condition report with 1-2-3 ratings |
| Standard | Industry-recognised but not RICS-regulated | RICS Home Survey Standard |
If you’re buying a new-build, both can have value. The snagging survey gets the developer to fix issues; the home survey gives you a formal condition record at the point of purchase.
Who carries out a snagging survey?
Snagging surveys are carried out by independent snagging surveyors, often including surveyors with construction or building inspection backgrounds. Survey Hut is based in Altrincham and carries out snagging surveys on new-build properties across the North West, with the detail and photographic evidence developers respond to.
FAQs
Can I do a snagging survey myself?
You can, but most buyers find an independent surveyor identifies two to three times the number of defects, particularly the technical issues (electrical, plumbing, regulatory compliance) that aren’t obvious without inspection experience.
Will the developer fix everything on the snag list?
They’re contractually obliged to fix defects covered by the warranty during the defects period (typically 2 years). In practice some items are negotiated. A clear, well-documented list with photographs strengthens your position considerably.
Is a snagging survey worth it if I’ve already moved in?
Yes, provided you’re still within the 2-year defects period. The developer remains responsible for fixing defects during that window. Many buyers leave it until close to the 2-year mark and then submit a comprehensive list while the warranty still applies.
