Heat loss survey for Wellingborough homes
Every property in Wellingborough is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Homeowners in Wellingborough thinking about insulation work can use the survey to see how it would change their heat pump size. Design outdoor temperatures for Wellingborough and the wider Northamptonshire come from local cold-weather data, not a national average.
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
- Homes with an existing heat pump that seems undersized or expensive to run
What's included
- Hot water cylinder sizing for your household
- Electrical supply and network operator notes
- 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
The survey in Wellingborough 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 Wellingborough 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 surveys in Wellingborough: questions
Do you cover Rushden as well as Wellingborough?
Yes. We arrange surveys and installation in Rushden, which is about 4 miles east of Wellingborough, and across Northamptonshire.
Where would the outdoor unit go on a Wellingborough 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 Wellingborough home.
How long does a heat pump survey take in Wellingborough?
A home survey in Wellingborough 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.
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.
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.
