How pricing is worked out
Every quote is built from the same three inputs: service scope, property size, and travel. You get the full price before booking, with no vague “starting from” conversation replacing an actual number.
Size uplifts
- Up to 200m²: base rate
- 200–300m²: +£100
- 300–400m²: +£200
- Each extra 100m²: +£100
Travel and location
Travel is priced by distance and access complexity. If a site has unusual access constraints, we call that out in the quote so there are no surprises on survey day or in the invoice.
Core package rates
- ASHP survey pack: from £250
- ASHP survey + heat loss: £350
- Solar PV survey pack: from £200
- Heat loss only: £150
Frequently asked questions
How much does a heat pump survey cost?
ASHP surveys from £250 (up to 200m²). ASHP + heat loss £350; heat loss alone £150. Distance from Doncaster and property size affect price. We confirm scope and pricing before booking.
How much does a solar survey cost?

How much do heat loss calculations cost?
Heat loss calculations are £150 when booked separately. We can produce them from a Vertex site visit or fully remotely (desktop) from floor plans and room-by-room measurements you send us — no property visit needed for the desktop option. Save £50 by choosing our Survey + Heat Loss package for £350 (vs £400 if booked separately).
