Pre-Completion Inspection vs Post-Completion Survey

You get two chances to check your new-build home. Most buyers only use one.

A quick check before you complete is a good start. But the defects that cost the most – missing insulation, hidden leaks, damp – usually only show up once you've got the keys and the heating's on.

93.7%

of new-build buyers reported at least one issue to their builder after moving in – and more than a quarter reported over 15.

Why it matters

Why choose a Post-Completion Survey?

More thorough

Not limited to the PCI checklist, so issues hidden behind finishes – such as insulation gaps or damp – can be found.

Stronger evidence

Thermal images and test readings give your developer clear, objective proof – making defects harder to dispute.

Real-world conditions

With the heating on and the home lived in, cold spots, draughts and condensation show up properly.

Still protected

Defects reported within the first two years remain the developer's responsibility under the New Homes Quality Code.

Common questions

Can I have both?

Yes. A PCI is a useful quick check before you move in, and a Post-Completion Survey after you get the keys gives you a far more complete picture, with specialist evidence to get defects fixed.

Is it too late if I've already moved in?

No. A Post-Completion Survey is carried out after you receive the keys – ideally within the two-year builder warranty period, while defects remain the developer's responsibility.

Why does thermal imaging matter?

It identifies insulation gaps, cold bridging, air leakage and concealed leaks – problems hidden behind finishes that a visual checklist inspection cannot see.

What do I get at the end?

A full, independent report tailored to your property: a photographic schedule, thermal images and test readings, ready to submit to your developer and warranty provider.
