What to know about heat loss surveys in Prescot
A heat pump suits most Prescot homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Homeowners in Prescot thinking about insulation work can use the survey to see how it would change their heat pump size. A surveyor visits your Prescot home to measure each room, window and wall before any heat pump is sized.
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.
- Landlords comparing properties before deciding where to switch first
- Self-builders and architects who need emitter and system sizes early
- Homes with an existing heat pump that seems undersized or expensive to run
What's included
- Written results in your quote, or a stand-alone report if you order one
- Room-by-room heat loss calculation using the MCS method
- Recommended heat pump size and design flow temperature
- Hot water cylinder sizing for your household
- Outdoor unit siting options and noise check
For Prescot homes with extensions or loft conversions, each part of the house is assessed on its own construction.
Grants and rules for heat pumps in England
Homes in Prescot 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.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
How long is the heating season in Prescot?
On the shortest day Prescot gets only about 7 hours 29 minutes of daylight and the noon sun sits around 13° above the horizon. Northern winters tend to be longer, so a well-designed, efficient system matters more here because it runs for more of the year.

Heat loss surveys in Prescot: questions
How long does installation take in Prescot?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Prescot home states the expected time.
How soon can you survey a home in Prescot?
Survey dates depend on how busy installers are in Merseyside. We offer the next available dates when you enquire and confirm them in writing.
Can you service a heat pump in Prescot that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Prescot, whoever fitted them. Tell us the make and model when you book.
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.
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.
