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
- 400–500m²: +£300
- 500m²+: manual review
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.

Frequently asked questions
How much does a heat pump survey cost?
ASHP surveys from £250 (up to 200m²). ASHP plus heat loss is £350. Standalone heat loss calculations start at £150 when reliable input evidence already exists. Distance from Doncaster and property size affect price. We confirm scope and pricing before booking.
How much does a solar survey cost?
Solar survey: from £200. We confirm scope, timeline, and final price before booking. Pricing varies with property size, roof complexity, travel, and any battery or electrical extras.
How much do heat loss calculations cost?
Standalone heat loss calculations start at £150 when reliable drawings, room measurements, or Vertex survey data already exist. If we need a separate site visit to gather the inputs, survey pricing applies. ASHP plus heat loss is £350, saving £50 versus booking the two outputs separately.
How much does a battery storage survey cost?
Battery storage surveys start at £100. The final quote still depends on property size, travel, and any unusual siting constraints, but the base route is public.
