About our air source heat pumps in Sydenham
As an MCS certified installer, we fit air source heat pumps for homes in Sydenham and the rest of Greater London. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We help you work out which suits your home. The work covers homes heated by oil, LPG or gas, radiator systems and hot water cylinders, and the jobs we see most are an oil, LPG or gas boiler near the end of its life and no space for a hot water cylinder.
A terrace in Sydenham shares walls with its neighbours, which helps keep heat in, provided the outdoor unit can sit somewhere that passes the MCS noise check.
We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

How it works
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. Before we leave, the area is tidied and we explain what we have done. Pictures of the space and the outside wall help us plan the work in Sydenham.
- We start with your plans and the property.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- We install the heat pump and connect it up.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
How to prepare
- Have the make and model of any existing unit to hand
- Tell us about access, such as roof hatches, high walls or locked plant areas

Heat pumps in Sydenham: local notes
About 40% of homes in Sydenham and the neighbourhoods around it were built before 1919, according to the Valuation Office Agency’s council tax figures, and Census 2021 figures found about 59% of households live in flats. In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. Flats are often harder for air-to-water systems, so we look at whether air-to-air suits better. In London, outside space and the rules for flats often decide which kind of heat pump suits.
If you live near Sydenham station, the survey compares air-to-water and air-to-air for your home before anything is quoted. Older homes near Church of St Bartholomew may need extra checks for planning and heat loss before a heat pump is designed.

Questions from Sydenham
Is a heat pump in Sydenham permitted development?
It depends on the property. The Cobb's Corner Conservation Area is close to the centre of Sydenham. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the planning department at Lewisham council, typically the authority for Sydenham.
Can you fit air conditioning in a London flat in Sydenham?
In many cases, yes, once the lease and the building’s rules are checked. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Can you set up regular servicing?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is recorded, with F-Gas records where refrigerant work is involved.
Is there a survey before the work?
Yes. Photos often do the job for simple work, while larger systems and faults that need testing are seen on site.
Is the equipment covered by a warranty?
The manufacturer provides it, on its own terms. Some terms depend on regular servicing by a qualified engineer, so keep your service records.
Which type of heat pump is right for my home?
Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. With air-to-air, hot water needs another source, and we explain which suits your home.
Will skipping a service affect the warranty?
For some brands, yes. Read the manufacturer’s terms, or send us the make and model and we will explain them, and book the service at the interval they recommend.

How we price air source heat pumps
You will get a fixed price before any work starts. It’s based on:
- Whether we need access equipment for high-level work
- Whether the existing supply is suitable
- The type of system, from a single split to a larger system
No two properties are the same, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all play a part.
Before you get in touch
A few details help us quote accurately. When you get in touch, it helps to send:
- Your installation or service records
- The postcode and whether it’s a home, flat or business
- A few pictures of the room and the wall the unit is on, or will go on
