Lewisham questions
Can I get the Boiler Upgrade Scheme grant in Lewisham?
Yes, the scheme covers homes in England, including Lewisham, if they qualify. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. The installer applies, and we’re MCS certified.
Can you fit air conditioning in a London flat in Lewisham?
Often, yes, but the lease and the freeholder normally have a say. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will tell you what to do first.
Will I get records for the system?
Yes. Each visit is written up, including F-Gas records for any refrigerant work. Keep them with the manual and the warranty documents.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
Should I choose air-to-water or air-to-air?
Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. Air-to-air does not heat hot water, and we explain which suits your home.
Who is responsible for leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
How we handle air source heat pumps in Lewisham
As an MCS certified installer, we fit air source heat pumps for homes in Lewisham and the rest of Greater London. There are two kinds: air-to-water, which heats radiators or underfloor heating and your hot water, and air-to-air, which warms rooms through indoor units and can also cool. We will explain which type fits your home and why. Typical jobs include questions about where the outdoor unit can go and checking eligibility for a heat pump grant, on homes heated by oil, LPG or gas, underfloor heating and air-to-air heat pumps.
In a flat in Lewisham, the lease and the freeholder typically decide where a heat pump can go. The planning rules for flats are stricter than for houses, and we check before designing.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork, because it helps with any later warranty question.

How it works
Protection comes first: dust sheets over floors and furniture near the work, and we ask before moving anything. After that, anything electrical is made safe and we start. The work on site takes a few days on site, depending on the cylinder, the radiators and the pipework involved, and we tidy up before we leave. In a London area like Lewisham, parking and access are worth sorting out before the day.

What owners can safely do
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. Ask us to quote for a move instead.
Air source heat pumps around Lewisham
Valuation Office Agency council tax records put about 37% of homes in and around Lewisham before 1919, and the last census (2021) found about 69% of households live in flats. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. For flats, the first questions are where an outdoor unit could go, whether a cylinder fits and what the lease allows. For a London home, the outdoor unit position and the MCS noise check need careful planning.
For a home near Lewisham station, the survey looks at whether an air-to-water or air-to-air heat pump suits better. Queen's House lies about 1.4 miles north. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.
