ASHP survey requirements in the UK

This is the evidence installer teams normally need before design starts and the job moves forward.

Core ASHP survey requirements

Why the report layout matters in the UK

Faster quoting

Clear documentation makes first-pass quotes easier.

Cleaner design sign-off

Design decisions are easier when evidence and assumptions are explicit.

Fewer install-day surprises

Constraints are documented before teams are on site.

What Vertex sends back

One clear report, same layout each time, checked before release, with the constraints and unknowns called out plainly.
