The Appraisal

What happens in
sixty minutes.

Most homeowners have had three builders in who gave three different answers. An appraisal gives you the structural truth before the commercial pressure starts.

01

Book a slot

5 min

Confirm your postcode is in our service area and choose a morning or afternoon block. We cover London, Bristol, Leeds, Manchester, and Brighton.

We confirm within two hours. No deposit required.

02

On-site appraisal

60 min

We arrive with a laser measure, head-height pole, and torch. We climb into the void, measure every rafter span, purlin position, and ridge height. We photograph the structure and assess the load path to foundations.

You don't need to prepare anything. Just access to the loft hatch.

03

Structural assessment

Same day

We confirm head height at the purlin, joist span and strength, chimney stack positions, and any party wall implications. We identify the conversion type your roof structure supports.

This is what separates an appraisal from a builder's estimate.

04

Written report

48 hrs

A clear written report covering: viable conversion types, permitted development eligibility vs. full planning, estimated build cost range, and a realistic property value uplift based on recent comparable sales.

The report is yours to share with any builder or estate agent.

We'd had two builders in who told us completely different things. The appraisal report settled every argument — we knew exactly what we had, what it would cost, and what it would add to the house. We booked the builder three days later.

I wanted a studio for teaching but wasn't sure the roof would allow it. The report came back with three options at three price points. I chose the rooflight conversion — done in seven weeks, planning-free. I teach piano up there every Tuesday.

I needed to know the payback period before I committed. The report gave me the build cost range, the rental uplift, and the capital value increase. Payback: sixteen months. I've since had three more properties appraised.
