Air source heat pumps for homes and businesses in Force Green
An air-to-water heat pump heats water to a lower temperature than a typical boiler which means some radiators may need upsizing. We check each radiator against the room’s heat loss and anything that needs changing is in the quote. We are often asked to deal with moving away from fossil-fuel heating and replacing a combi boiler with a heat pump, across radiator systems, homes heated by oil, LPG or gas and hot water cylinders.
A terrace in Force Green 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.
Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

How it works
The first job on site is protection: sheets over the floor and any furniture nearby and nothing is moved without asking you. Then the electrics are made safe and the work begins. The work on site takes a few days on site, depending on the cylinder, the radiators and the pipework involved, and we clear up before we go. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Force Green.
- We talk through your home, your current heating and what you want from a heat pump.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- The system is commissioned and registered under MCS, and we show you how to use it.
How to prepare
- Clear a path to the units and the space around them
- Mention any parking restrictions near the property
- Let us know where the consumer unit is

Force Green questions
Can I have air conditioning in a flat in Force Green?
Typically, yes, though leaseholders normally need the freeholder’s agreement. 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 I need planning permission for a heat pump in Force Green?
That depends on the building and where the outdoor unit goes. The centre of Force Green is in a conservation area. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit can’t face a road. Where necessary, we check with Sevenoaks council, which is typically the planning authority for Force Green.
Can I do the refrigerant work myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Can you look at a system you didn’t fit?
Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.
What VAT do I pay on a heat pump?
Installing an air source heat pump in a home is zero-rated until 31 March 2027, then 5%. It doesn’t apply to businesses. This is general information, not tax advice.
Will my radiators work with a heat pump?
The heat loss survey answers that, room by room. Where a radiator is already large enough, it stays, and any that need upsizing are set out in the quote.
Is there a Boiler Upgrade Scheme grant for air-to-air?
It can, as long as the system takes over the heating completely. The £2,500 applies when it replaces the fossil-fuel heating, covers the full heating demand, is fitted by an MCS certified installer and serves a home; as an add-on to a boiler it doesn’t qualify.
How the job changes from property to property
Air-to-air heat pumps
Air-to-air heat pumps are now covered by permitted development rules in England, subject to conditions. Cooling-only units are not included, so check with the council.
The Boiler Upgrade Scheme
Not every home qualifies, so we check before you commit.
Signs you need air source heat pumps in Force Green
Many people look at heat pumps when an oil, LPG or gas boiler is getting old. Planning the change before the boiler fails gives you time to survey, design and apply for any grant, rather than rushing a replacement in winter.
Keep an eye out for any of the following:
- Working out where a cylinder could go
- Ageing boilers that will need replacing
- Finding a place for the outdoor unit
Live in one of the older houses around Church of St Mary the Virgin? Expect the survey to look closely at heat loss and at the building’s planning status.
What to look for in a quote
- Who does the electrical work, and whether they can certify it
- Whether the quote is a fixed price
- Whether extra work needs your approval first
Heat pumps in Force Green: local notes
About 40% of homes in Force Green and the neighbourhoods around it were built before 1919, according to Valuation Office Agency council tax records, and about 64% of households live in detached or semi-detached houses, according to the 2021 Census. Period properties can still suit a heat pump, but the design has to start from accurate heat loss figures. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder. For a London home, the outdoor unit position and the MCS noise check need careful planning.
Quebec House lies about 0.8 miles south. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.

Safe owner checks
Owner care supports servicing; it doesn’t replace it. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
