Heat loss survey for Wallasey homes
In Wallasey, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Design outdoor temperatures for Wallasey and the wider Merseyside come from local cold-weather data, not a national average. For Wallasey homes with extensions or loft conversions, each part of the house is assessed on its own construction.
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
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Anyone getting a heat pump quote, as the first step
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
- Electrical supply and network operator notes
- Radiator schedule with any upgrades needed for each room
- Outdoor unit siting options and noise check
Homeowners in Wallasey thinking about insulation work can use the survey to see how it would change their heat pump size.
Grants and rules for heat pumps in England
Homes in Wallasey 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.
Heat loss survey costs around Wallasey
The ranges below are typical installed prices for homes in Merseyside, including VAT. A survey sets the exact figure, because two similar-looking houses in Wallasey 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.
Short winter days in Wallasey and what they mean
On the shortest day Wallasey 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 Wallasey: questions
How long does a heat pump survey take in Wallasey?
A home survey in Wallasey 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.
Can you service a heat pump in Wallasey that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Wallasey, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Wallasey home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Wallasey home.
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.
