Heat loss survey in Thatcham: what to expect
Every property in Thatcham 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.
The survey in Thatcham includes a check of where the outdoor unit could sit and how its sound would reach neighbours. Houses in Thatcham built in different eras can need very different heat pump sizes, which is why each is calculated room by room.
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.
- Landlords comparing properties before deciding where to switch first
- Homes with an existing heat pump that seems undersized or expensive to run
- Homeowners planning insulation or building work who want to know the effect on heat demand
What's included
- Written results in your quote, or a stand-alone report if you order one
- Room-by-room heat loss calculation using the MCS method
- Outdoor unit siting options and noise check
- Radiator schedule with any upgrades needed for each room
- Hot water cylinder sizing for your household
Design outdoor temperatures for Thatcham and the wider Berkshire come from local cold-weather data, not a national average.
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 Thatcham 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.

| Home survey and heat loss calculation with an installation quote | Free |
| Stand-alone heat loss survey and report | £160–£420 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Winter daylight and heating in Thatcham
Thatcham sees roughly 7 hours 51 minutes of daylight in late December against 16 hours 37 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 Thatcham: questions
How long does installation take in Thatcham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Thatcham home states the expected time.
Do you cover Newbury as well as Thatcham?
Yes. We arrange surveys and installation in Newbury, which is about 3 miles west of Thatcham, and across Berkshire.
Can you service a heat pump in Thatcham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Thatcham, whoever fitted them. Tell us the make and model 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.
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.
