How it works
Exactly what happens — before, during and after your assessment.
Most people have never watched an energy assessment. Here's the whole process, so there are no surprises on the day and nothing that delays your certificate.

Before
Booked in two minutes, confirmed in writing.
Book online with the fixed price shown, or call and we'll do it for you. Your confirmation email includes the assessor's name and ID number so you know exactly who to expect.

On the day
A methodical survey — not a walk-round.
The assessor works room by room in a set order so nothing is missed. You're welcome to follow along and ask questions; many customers find it genuinely useful.
