What Is a Post-Completion Snagging Survey – and Do You Still Need One After Moving In?

Home -

Just moved into your brand-new home and noticing things aren’t quite perfect? From stiff doors to leaky radiators, these small defects—called “snags”—can quickly add up. A Post-Completion Snagging Survey is your last chance to hold the builder accountable before your warranty runs out.

Here’s what it is, why it matters, and how to book one.

What Is a Post-Completion Survey?

A post-completion survey is a professional inspection carried out after you’ve already moved into your new-build home. It checks the build quality, finishes, and compliance with the New Homes Quality Code, highlighting any issues that should have been addressed before completion.

Even though you’re now living in the property, you still have time—typically up to 2 years under warranty—to get defects fixed.

Why Not Just Report Snags Yourself?

You can, but without a structured report, many snags are missed or dismissed. Builders are much more likely to act when defects are clearly documented and prioritised by a RICS-registered surveyor.

Our inspections cover:

Brickwork and roof condition
Window and door seals
Insulation and loft access
Kitchen and bathroom finish
Heating, electrics, and plumbing
Garden levels, drainage, and boundary lines

It’s a thorough check, not just a “walkaround.”

When Should You Book One?

Within the first few months of moving in
If you missed the pre-completion snagging window
Before your 2-year builder’s warranty expires
If the house doesn’t feel “right” and you want peace of mind
When the developer is slow or evasive about fixing issues

Don’t wait too long—snags are best caught while the builder still has obligations to you.

Real Example: 37 Snags in a 4-Month-Old House

A recent client booked our post-completion survey after feeling ignored by their developer. The report revealed 37 snags, including a poorly aligned loft hatch, chipped tiles, a slow drainage slope on the drive, and no insulation behind kitchen units. The builder fixed most within three weeks.

Without the report? They’d have continued chasing vague promises.

What Happens After the Survey?

You’ll get a PDF report within 24 hours, with:

Photos of each issue
Severity codes (cosmetic to safety-critical)
Clear recommendations you can forward to the developer

We can also support you with any follow-up if the builder doesn’t respond.

Still Not Sure If It’s Worth It?

Even a few snags can cost hundreds to fix later—and you’ve already paid for the home to be right. Our clients often save far more than the cost of the inspection by getting these issues resolved under warranty.
