Heat loss survey in Catford: what to expect
Every property in Catford 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 Catford includes a check of where the outdoor unit could sit and how its sound would reach neighbours. A surveyor visits your Catford home to measure each room, window and wall before any heat pump is sized.
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
- Self-builders and architects who need emitter and system sizes early
What's included
- Recommended heat pump size and design flow temperature
- Room-by-room heat loss calculation using the MCS method
- Hot water cylinder sizing for your household
- Outdoor unit siting options and noise check
- Radiator schedule with any upgrades needed for each room
For Catford homes with extensions or loft conversions, each part of the house is assessed on its own construction.
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 Catford 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 Catford and what they mean
On the shortest day Catford 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 Catford: questions
Can you service a heat pump in Catford that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Catford, whoever fitted them. Tell us the make and model when you book.
Do I need new radiators for a heat pump in Catford?
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 Catford home gives a room-by-room list.
How long does a heat pump survey take in Catford?
A home survey in Catford 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.
