What to know about heat loss surveys in Bexleyheath
The question for a Bexleyheath home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Houses in Bexleyheath built in different eras can need very different heat pump sizes, which is why each is calculated room by room. For Bexleyheath homes with extensions or loft conversions, each part of the house is assessed on its own construction.
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
- Self-builders and architects who need emitter and system sizes early
What's included
- Radiator schedule with any upgrades needed for each room
- Room-by-room heat loss calculation using the MCS method
- Electrical supply and network operator notes
- Written results in your quote, or a stand-alone report if you order one
- Hot water cylinder sizing for your household
Homeowners in Bexleyheath thinking about insulation work can use the survey to see how it would change their heat pump size.
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 Bexleyheath quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

Short winter days in Bexleyheath and what they mean
On the shortest day Bexleyheath gets about 7 hours 50 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Heat loss surveys in Bexleyheath: questions
What size heat pump does a Bexleyheath home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Bexleyheath home.
Can you service a heat pump in Bexleyheath that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Bexleyheath, whoever fitted them. Tell us the make and model when you book.
How long does a heat pump survey take in Bexleyheath?
A home survey in Bexleyheath 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.
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.
How long does a heat loss survey take?
A typical survey takes 1–3 hours on site, depending on the size and complexity of the home. Larger or older houses with mixed construction, extensions or many rooms take longer. The calculations and design are completed afterwards, and the results are included in your quote or stand-alone report.
