Heat loss survey for West Hampstead homes
Most homes can run on a heat pump if the system is designed properly, and West Hampstead is no different. The key is matching the heat pump and radiators to the home's heat loss.
Homeowners in West Hampstead thinking about insulation work can use the survey to see how it would change their heat pump size. The survey in West Hampstead 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.
- Anyone getting a heat pump quote, as the first step
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Homes with an existing heat pump that seems undersized or expensive to run
What's included
- Outdoor unit siting options and noise check
- Room-by-room heat loss calculation using the MCS method
- Recommended heat pump size and design flow temperature
- Electrical supply and network operator notes
- Hot water cylinder sizing for your household
Design outdoor temperatures for West Hampstead and the wider Greater London come from local cold-weather data, not a national average.
Grants and rules for heat pumps in England
Homes in West Hampstead 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.

Designing for West Hampstead's winters
West Hampstead sees roughly 7 hours 49 minutes of daylight in late December against 16 hours 39 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Heat loss surveys in West Hampstead: questions
How long does installation take in West Hampstead?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a West Hampstead home states the expected time.
Do I need new radiators for a heat pump in West Hampstead?
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 West Hampstead home gives a room-by-room list.
How soon can you survey a home in West Hampstead?
Survey dates depend on how busy installers are in Greater London. We offer the next available dates when you enquire and confirm them in writing.
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.
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.
