Heat pump installers in Colliers Wood
For air source heat pumps in Colliers Wood, one call is all it takes: diagnosis, fixed price, work and sign-off. F-Gas certified, NICEIC approved and Checkatrade members.
- Questions about where the outdoor unit can go
- Questions about the Boiler Upgrade Scheme
- No space for a hot water cylinder
How it works
The work area is kept tidy throughout, with sheets down and mess cleared as we go. If we need to drill through a wall, we agree the spot with you first. On site, it takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. If a freeholder or agent needs to agree the work in Colliers Wood, we can send them the details.
- First we find out about the property, the heating you have now and what you are hoping for.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
How to prepare
- Clear the space around the indoor unit, or where it will go
- Have the make and model of any existing unit to hand
- Keep pets out of the rooms we’re working in

Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and many jobs can be priced from that.

About our air source heat pumps in Colliers Wood
We install air source heat pumps in Colliers Wood and across Greater London, and we’re MCS certified. 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 hot water cylinders, radiator systems and homes heated by oil, LPG or gas, and the jobs we see most are plans to switch to electric heating with a heat pump and a boiler that’s getting old.
A terrace in Colliers Wood shares walls with its neighbours, which helps keep heat in, as long as there’s a sensible spot for the outdoor unit and its noise is checked against the MCS planning standard.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

Heat pumps in Colliers Wood: local notes
About 55% of homes in Colliers Wood and the neighbourhoods around it were built before 1919, according to the Valuation Office Agency’s council tax figures, and about 56% of households live in flats, according to Census 2021 figures. 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. In flats, space for an outdoor unit and a cylinder can be limited, and the lease and freeholder come into it, so air-to-air is sometimes the better fit. For a London home, the outdoor unit position and the MCS noise check need careful planning.
If your home is listed, like Southside House about 2.8 miles west, listed building consent comes before any heat pump work. For a home near Tooting station, the survey looks at whether an air-to-water or air-to-air heat pump suits better.
Colliers Wood is about 5 miles south of Brompton, in Greater London. Wherever you are in the SW17 postcode area, our engineers can take on air source heat pumps. Colliers Wood is one of 764 towns, villages and districts in Greater London where we work for homes and businesses.
Not far from Colliers Wood, a recent job of ours was on Streatham High Road, Streatham (SW16), about 2 miles east: installing two LG wall-mounted units in the main nail bar area and a third unit in the treatment room.
Here we cover the SW17, SW19 and CR4 postcode area. Local streets include Acre Road, Boyd Road and Park Road, and we cover them all.

Leave it or put it right?
Choosing between air-to-water and air-to-air is easier with the facts. Air-to-water works with radiators and a cylinder, with a £7,500 grant for eligible homes, while air-to-air heats and cools rooms and has a £2,500 grant only in limited cases. We explain which makes sense for you. In a London building, getting the freeholder’s or agent’s agreement can take a while, so it’s worth starting early.
Whatever the property, the quote works the same way: the equipment, the access, the work involved and the time it takes. Call for a fixed-price quote and we will explain each part.

Colliers Wood: your questions answered
Does the Boiler Upgrade Scheme cover homes in Colliers Wood?
Yes, the scheme covers homes in England, including Colliers Wood, if they qualify. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. The installer applies, and we are MCS certified.
Can you fit air conditioning in a London flat in Colliers Wood?
Usually, yes, though leaseholders normally need the freeholder’s agreement. 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.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
What does F-Gas certified mean?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.
Do you provide F-Gas records?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, while repairs and services get a written note of what was found and done.
When will I hear back?
You’ll hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
How much time does a heat pump install need?
A typical installation takes a few days on site, depending on the cylinder, the radiators and the pipework involved. We plan the work so you’re without heating for as little time as possible and agreed before work begins.
Aftercare tips
Looking after the system is mostly common sense. A few tips:
- Keep up with insulation and draught-proofing
- Do not block radiators or indoor units with furniture
- Book a yearly service
We show you how to use the controls and explain how a heat pump works differently from a boiler. Heat pumps tend to work best running steadily rather than in short bursts, and we will explain the settings for your home.
Don’t cover radiators with furniture or heavy curtains so the heat can get into the room.
