Chelsfield: your questions answered
Is the heat pump grant available in Chelsfield?
Chelsfield is covered, as the scheme runs across England and Wales. 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. You do not apply yourself: the MCS certified installer does, which is us.
Do I need permission to put air conditioning in my flat in Chelsfield?
Often, yes, but the lease and the freeholder usually have a say. 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.
Is the equipment covered by a warranty?
Warranty comes from the manufacturer and depends on the brand and product. Daikin, for instance, gives a standard 2 years on split air conditioning and we explain the terms for your brand on the quote.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Which accreditations do you hold?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Will my radiators work with a heat pump?
Some radiators may be fine as they are, and some may need to be larger. Heat pumps run at lower flow temperatures, so radiators give out less heat, and the survey checks each one.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
Air source heat pumps for homes and businesses in Chelsfield
As an MCS certified installer, we fit air source heat pumps for homes in Chelsfield 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. We’re often asked to deal with checking whether planning permission is needed and moving away from fossil-fuel heating, across air-to-water heat pumps, underfloor heating and air-to-air heat pumps.
Homes in Chelsfield are often flats and terraces, where outside space is limited, which affects which heat pump suits. An air-to-water system needs space outside and normally a hot water cylinder inside, while an air-to-air system needs less space.
The records are your system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

What else we do in Chelsfield
The process
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. So on the day, you don’t need a separate electrician for the electrical side. The work takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. If your building in Chelsfield has a managing agent, a concierge or sign-in rules, mention them when you book.
- It begins with your house and the heating it relies on now.
- A heat loss survey is carried out, room by room.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- Cost, grant and VAT appear on one fixed-price quote.
- Then it’s fitted, commissioned and registered with MCS.
Getting ready for the visit
- Have the make and model of any existing unit to hand
- Keep pets out of the rooms we are working in
- Move furniture away from the wall where we will be working

Looking after it afterwards
Looking after it is simple, and it helps at the next service:
- Leave indoor units unobstructed
- Keep the outdoor unit clear all year
- Look at insulation alongside the heat pump
If anything does not seem right after installation, call 07833 053749 or email us and we’ll look into it. A yearly service is a good habit.
Heat pumps prefer steady, low-temperature running as explained at handover.
Common problems we fix in Chelsfield
Homes with electric heating sometimes look at heat pumps as an alternative. The survey tells you whether it’s practical and what’s involved, and we explain the grant position for your home.
The things we’re asked about most are:
- Deciding on the outdoor unit position
- Moving away from fossil-fuel heating
- Questions about the Boiler Upgrade Scheme
If your home is listed, like Lullingstone Castle about 3 miles east, listed building consent comes before any heat pump work.
Before you book anyone

Air source heat pumps around Chelsfield
Valuation Office Agency council tax records date about 59% of homes across Chelsfield and its surrounding area to the post-war years, 1945 to 1972, and the last census (2021) found about 70% of households in detached or semi-detached houses. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these. For a London home, the outdoor unit position and the MCS noise check need careful planning.
Live in one of the older houses around Church of St Martin of Tours? Expect the survey to look closely at heat loss and at the building’s planning status.
