Heat loss survey for Woking homes
Every property in Woking 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.
For Woking homes with extensions or loft conversions, each part of the house is assessed on its own construction. Homeowners in Woking thinking about insulation work can use the survey to see how it would change their heat pump size.
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
- Landlords comparing properties before deciding where to switch first
- Homeowners planning insulation or building work who want to know the effect on heat demand
What's included
- Recommended heat pump size and design flow temperature
- Radiator schedule with any upgrades needed for each room
- 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
A surveyor visits your Woking home to measure each room, window and wall before any heat pump is sized.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Woking quote.
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.
What to budget for heat loss surveys in Woking
These are guide prices for Surrey, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.
| Survey | Guide price |
|---|---|
| Home survey and heat loss calculation with an installation quote | Free |
| Stand-alone heat loss survey and report | £160–£430 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Designing for Woking's winters
Woking sees roughly 7 hours 51 minutes of daylight in late December against 16 hours 36 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.
The steps for heat loss surveys in Woking
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Woking; the surveyor measures rooms, windows and radiators and looks at cylinder space.

- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Heat loss surveys in Woking: questions
Can you service a heat pump in Woking that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Woking, whoever fitted them. Tell us the make and model when you book.
How long does a heat pump survey take in Woking?
A home survey in Woking 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.
How long does installation take in Woking?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Woking home states the expected time.
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.
Can I use the heat loss report to get other quotes?
Yes. A stand-alone heat loss report is yours to use, including sharing it with other installers so their quotes are based on the same figures. Comparing quotes like for like makes it easier to see differences in equipment, radiator upgrades and workmanship terms. The report states the assumptions used wherever construction could not be confirmed.
