Before you book: heat loss surveys in Grantham
Most homes can run on a heat pump if the system is designed properly, and Grantham is no different. The key is matching the heat pump and radiators to the home's heat loss.
Design outdoor temperatures for Grantham and the wider Lincolnshire come from local cold-weather data, not a national average. The survey in Grantham includes a check of where the outdoor unit could sit and how its sound would reach neighbours.
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
- Landlords comparing properties before deciding where to switch first
- 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
- Outdoor unit siting options and noise check
- Radiator schedule with any upgrades needed for each room
- Hot water cylinder sizing for your household
- Room-by-room heat loss calculation using the MCS method
A surveyor visits your Grantham home to measure each room, window and wall before any heat pump is sized.
Grants and rules for heat pumps in England
Homes in Grantham 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.
Guide prices for heat loss surveys in Grantham
The ranges below are typical installed prices for homes in Lincolnshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Grantham 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–£400 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Designing for Grantham's winters
On the shortest day Grantham gets about 7 hours 35 minutes of daylight, with the noon sun around 14° 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 Grantham: questions
Where would the outdoor unit go on a Grantham 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 Grantham home.
Can you service a heat pump in Grantham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Grantham, whoever fitted them. Tell us the make and model when you book.
Do I need new radiators for a heat pump in Grantham?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Grantham home gives a room-by-room list.
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.
