Heat loss survey for Alfreton homes
Homes around Alfreton range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Homeowners in Alfreton thinking about insulation work can use the survey to see how it would change their heat pump size. A surveyor visits your Alfreton 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.
- Self-builders and architects who need emitter and system sizes early
- Landlords comparing properties before deciding where to switch first
- Anyone getting a heat pump quote, as the first step
What's included
- Hot water cylinder sizing for your household
- Outdoor unit siting options and noise check
- Electrical supply and network operator notes
- Recommended heat pump size and design flow temperature
- Written results in your quote, or a stand-alone report if you order one
Design outdoor temperatures for Alfreton and the wider Derbyshire come from local cold-weather data, not a national average.
Grants and rules for heat pumps in England
Homes in Alfreton 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.

Designing for Alfreton's winters
On the shortest day Alfreton gets about 7 hours 33 minutes of daylight, with the noon sun around 13° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Heat loss surveys in Alfreton: questions
Do you cover Ripley as well as Alfreton?
Yes. We arrange surveys and installation in Ripley, which is about 4 miles south of Alfreton, and across Derbyshire.
Can you service a heat pump in Alfreton that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Alfreton, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on an Alfreton house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Alfreton home.
Is the heat loss survey free?
Yes, for installation enquiries the home survey and heat loss calculation are free, and the results form the basis of your written quote. If you only want the calculation and report, for example for building plans or comparing quotes, a stand-alone heat loss survey has a guide price of £150–£400, including VAT. We confirm which applies when you book.
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.
