Can I snag before legal completion?

Often yes, though it depends on the developer granting access. Ask in writing as early as possible, because pre-completion is when defects get resolved fastest.

How many snags is normal?

New homes are commonly handed over with a substantial list. The number matters less than the mix: a hundred cosmetic items is a different problem from three performance failures.

Is snagging the same as a survey?

No. Snagging measures finished work against build standards. A survey reports the condition of a building. On a new home you may sensibly want both at different moments.

What is a snagging survey?

A snagging survey is an independent inspection of a newly built home that records defects, unfinished work and items falling short of the applicable warranty and building standards. The output is a referenced, photographed schedule the developer can work through. It is a quality inspection of finished work, not a structural assessment and not a valuation.

At a glance

Timing: Ideally before legal completion; otherwise within the initial warranty period.
Output: Room-by-room schedule with references, photographs and locations.
Measured against: Warranty provider standards and building regulations requirements.
Not included: Valuation, structural design opinion, or negotiation with the developer.

What counts as a snag

A snag is work that is incomplete, defective, or below the standard the warranty provider and building regulations require. It ranges from a poorly hung door to missing loft insulation, absent cavity trays or drainage that has not been finished correctly.

The useful distinction in a report is between cosmetic items, which developers fix quickly, and performance items, which cost them more and therefore need to be documented precisely.

Internal finishes, doors, joinery, tiling and decoration
Loft: insulation coverage, ventilation, and completed detailing
External: brickwork, pointing, rainwater goods, drainage and ground levels
Services visible without dismantling: sanitaryware, sockets, ventilation terminals

Timing decides your leverage

Before completion, the developer wants the transaction to close and defects tend to be resolved quickly. After completion you rely on the developer's own defects process and the warranty provider's dispute route, which is slower.

Some developers resist pre-completion access for third-party inspectors. If access is refused, an inspection immediately after completion — well within the first warranty period — still puts a documented schedule in front of them at the point when your rights are strongest.

How the report is written to be actioned

Site managers respond to schedules that are specific: room, location within the room, description, photograph, and the standard it fails. Vague lists get argued about.

The report is structured so items can be ticked off and re-inspected, and so an unresolved item can be escalated to the warranty provider with the original evidence intact.

Who this is for

A good fit if

Buyers completing on a newly built house or apartment
Owners still within the initial warranty period
Anyone whose developer has closed a defects list they do not accept

Not the right choice if

Structural design opinions or calculations
Valuation or mortgage purposes
Older properties, where a condition survey is the right instruction

Getting the timing right

Three steps that decide how much the inspection is worth.

1.Request pre-completion access
Ask early and in writing. Even a partial inspection before completion is worth more than a full one afterwards.

2.Know your warranty period
The initial period, when the developer is directly responsible for defects, is short. Diary it.

3.Keep the evidence

Surveying advice

When to bring in a specialist

Electrical installations, gas, drainage and fire safety: instruct the relevant competent professional for testing and certification.
Warranty disputes and legal remedies: your conveyancer and the warranty provider's resolution service.
Movement requiring calculations, monitoring design or remedial design: instruct a structural engineer.

Common questions

Limitations and sources

Any survey is limited to what the surveyor can see and safely reach on the day. Areas behind finishes, under floors or beneath stored belongings are not opened up.
A snagging inspection does not open up completed work or test services.
It is not a RICS Home Survey and does not report on condition in the same terms.
Nothing on this page is a professional opinion about a specific property. KJ Surveyors has not inspected your building, and general guidance cannot replace an inspection and report.
