What to know about heat loss surveys in Rawtenstall
A heat pump suits most Rawtenstall homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Design outdoor temperatures for Rawtenstall and the wider Lancashire come from local cold-weather data, not a national average. Houses in Rawtenstall built in different eras can need very different heat pump sizes, which is why each is calculated room by room.
Every heat pump we quote starts with a room-by-room heat loss survey, free with installation enquiries and also available as a stand-alone report.
- Homes with an existing heat pump that seems undersized or expensive to run
- Anyone getting a heat pump quote, as the first step
- Self-builders and architects who need emitter and system sizes early
What's included
- Hot water cylinder sizing for your household
- Written results in your quote, or a stand-alone report if you order one
- Recommended heat pump size and design flow temperature
- Outdoor unit siting options and noise check
- Room-by-room heat loss calculation using the MCS method
The survey in Rawtenstall includes a check of where the outdoor unit could sit and how its sound would reach neighbours.
Grants and rules for heat pumps in England
Homes in Rawtenstall can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.
Heat loss survey prices in Rawtenstall
The ranges below are typical installed prices for homes in Lancashire, including VAT. A survey sets the exact figure, because two similar-looking houses in Rawtenstall can need quite different radiators and pipework.
| Survey | Guide price |
|---|---|
| Home survey and heat loss calculation with an installation quote | Free |
| Stand-alone heat loss survey and report | £150–£390 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.

Heat loss surveys in Rawtenstall: questions
How long does installation take in Rawtenstall?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Rawtenstall home states the expected time.
How long does a heat pump survey take in Rawtenstall?
A home survey in Rawtenstall usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
How soon can you survey a home in Rawtenstall?
Survey dates depend on how busy installers are in Lancashire. We offer the next available dates when you enquire and confirm them in writing.
Why can't you size the heat pump from my boiler?
Boilers are often much larger than a home's real heat loss, because they are sized for fast hot water and quick warm-ups. Matching a heat pump to the boiler's output usually means an oversized unit that costs more and switches on and off too often. A room-by-room calculation finds the actual heat demand, which is what the heat pump needs to meet.
What is a design flow temperature?
The design flow temperature is the temperature of the water sent to your radiators or underfloor heating on the coldest design day. Heat pumps are more efficient at lower flow temperatures, typically around 35–50°C. Choosing it is a balance: a lower figure improves efficiency but can mean larger radiators in some rooms, so the design shows both.
