What to know about air source heat pump installation in Blackheath
A heat pump suits most Blackheath homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
For older properties in Blackheath, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized. Many homes in Blackheath have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Homes replacing a gas, oil, LPG or electric heating system
- Houses with reasonable insulation, or a plan to improve it
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
What's included
- Radiator and pipework changes where the design needs them
- MCS registration and certificate, plus network operator notification
- Commissioning, handover and a walk-through of the controls
- Boiler Upgrade Scheme application in England and Wales where eligible
- Removal of the old boiler or heaters
Installers working in Blackheath plan the order of work so heating and hot water are off for as short a time as practical.
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 Blackheath 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.

Designing for Blackheath's winters
On the shortest day Blackheath 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.

Air source heat pump installation in Blackheath: questions
How soon can you survey a home in Blackheath?
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.
Can you service a heat pump in Blackheath that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Blackheath, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Blackheath?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Blackheath home states the expected time.
Will an air source heat pump be noisy?
Heat pumps are designed to run quietly, but where the unit sits makes a real difference. The survey looks for a position away from bedroom windows and neighbours, with clear airflow, and the installation must pass the MCS noise assessment. The fan is most noticeable on very cold days when the unit works hardest, and a little vapour during the periodic defrost is normal.
Can I cancel after accepting the quote?
Nothing is ordered until you accept the written quote. Where the contract is agreed away from our premises, for example at your kitchen table, you can cancel within 14 days under the Consumer Contracts Regulations 2013. If you ask us to start sooner and then cancel, you pay only for work done up to that point.
