A snagging list is a detailed checklist of defects, incomplete items, and poor-quality finishes identified in a property—most commonly a new-build or newly renovated home. It’s used to record what needs correcting so the builder, developer, or contractor can put things right.
Think of it as a structured way of saying: “These are the things that aren’t finished properly, don’t work as they should, or don’t meet an acceptable standard.”
A snagging list isn’t only useful for new builds. It can also be valuable for:
- newly refurbished houses
- extensions and loft conversions
- properties that have recently undergone major internal works
Anywhere workmanship and completion quality matter, snagging matters.
What a snagging list typically includes
A good snagging list usually covers three types of issues:
1) Cosmetic and finishing defects
These are the most common and easiest to spot:
- uneven paintwork, drips, roller marks, poor cutting-in
- scratched glass, chipped window frames, damaged doors
- cracked plaster, nail pops, poor caulking and sealant
- uneven tiling, loose tiles, poor grout lines
- gaps around skirting boards, architraves and fitted units
- scuffed floors, poorly fitted carpets, damaged laminate edges
These items may not be “structural”, but they affect quality, appearance, and long-term durability.
2) Functional defects (things that don’t work properly)
A snagging inspection should also check how the property functions day-to-day:
- doors sticking or not latching properly
- windows not opening smoothly or not locking correctly
- leaking taps, low water pressure, slow drainage
- extractor fans not working or venting incorrectly
- radiators not heating evenly, controls not operating as expected
- loose sockets, misaligned switches, tripping RCDs (where visible symptoms exist)
These are often the defects that become annoying—and expensive—if not fixed early.
3) Compliance and “fit-for-purpose” concerns
This is where a professional snagging inspection adds real value, because it looks beyond “does it look tidy?” and asks “is it right?”
Examples include:
- poor ventilation provision or missing trickle vents
- inadequate sealing around baths/showers leading to water ingress risk
- incorrectly installed insulation in accessible areas (where visible)
- missing fire-stopping details in cupboards/loft access points (where accessible)
- incomplete external sealing allowing draughts and moisture pathways
Not every snagging service goes into this depth, but higher-quality snagging inspections often include these “performance” issues—not just cosmetics.
When should you get a snagging list?
Timing matters. The best time is typically:
New-builds
- Before legal completion if the developer allows access (ideal)
- Immediately after completion if pre-completion access isn’t possible
- Often within the developer’s initial defects liability period (commonly the first 1–2 years, depending on contract/warranty terms)
Renovations, extensions and loft conversions
- At practical completion (when the contractor says the work is finished)
- Before final payments are released (snagging helps you retain leverage)
Why snagging lists are so valuable
A snagging list helps you:
1) Protect your investment
Small defects become larger ones if ignored—especially anything involving:
- water (leaks, poor sealing, external gaps)
- ventilation (condensation and mould risk)
- incomplete finishes (gaps that allow draughts and moisture)
2) Get defects corrected while you have leverage
Once you’ve moved in or paid the final amount, defects can take longer to resolve. A snagging list gives you a clear, formal record while the builder is still responsible.
3) Avoid disputes
A written list with photographs is hard to argue with. It sets expectations clearly and avoids vague back-and-forth conversations.
4) Improve comfort and livability
Snagging isn’t just about looks. It’s about:
- doors and windows functioning properly
- heating and ventilation working as expected
- sealing and finishing preventing draughts and leaks
- ensuring the home feels “complete” rather than “almost finished”
What makes a snagging list “good” rather than basic?
A strong snagging list is:
- room-by-room and elevation-by-elevation (not general notes)
- specific (exact location and clear description of defect)
- prioritised, where appropriate (urgent vs minor)
- supported with photographs
- written in a format that’s easy to share with a developer or contractor
It should also include items that buyers often miss, like:
- seals behind baths and shower trays
- loft hatch insulation/air leakage
- window operation and locking checks
- external drainage falls and splashback zones
- weep holes, air bricks and ventilation provisions
Snagging list vs survey: what’s the difference?
- A snagging list focuses on workmanship, completion and defects—especially in new-builds or recent refurbishments.
- A Level 2 or Level 3 Survey is aimed at overall property condition, risks, and longer-term maintenance (typically for pre-purchase).
They serve different purposes. If you’re buying a new-build, you may benefit from both—depending on what stage you’re at and what reassurance you need.
