Air source heat pumps in Larkfield
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. The Boiler Upgrade Scheme can provide £7,500 towards an eligible air-to-water system in England and Wales and the installer makes the application. Eligibility depends on the property, so we confirm it before anything is agreed. Common call-outs are for working out where a cylinder could go and moving away from fossil-fuel heating, across underfloor heating, homes heated by oil, LPG or gas and hot water cylinders.
In a place like Larkfield, some homes are listed, because permitted development does not apply within the grounds of a listed building, so we check consent first.
Each manufacturer sets its own warranty period. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

Rented and managed buildings
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We are happy to deal with either side and send the records to whoever needs them.
From a single flat to a whole estate, the approach is the same: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
After we’ve gone
Aftercare is straightforward, and it helps at the next service:
- Look at insulation alongside the heat pump
- Leave indoor units unobstructed
- Keep to regular servicing
After commissioning, the installation is registered under MCS and you receive the certificate. File it with the warranty documents, as you may need it later.
Let the heat pump run steadily rather than switching it on and off, using the settings agreed at handover.
Common questions in Larkfield
Will you come out to Larkfield?
Yes, and the size of the place makes no difference to how we work. A few pictures and the postcode are enough to get things started.
Is the heat pump grant available in Larkfield?
Larkfield is covered, as the scheme runs across England and Wales. The amount depends on the type of heat pump, and the survey confirms which applies. You don’t apply yourself: the MCS certified installer does, which is us.
Do you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and tell you why.
Will you make a mess?
We start with protection: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
Can you set up regular servicing?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water suits homes with radiators and a cylinder; air-to-air suits rooms that need heating and cooling, and we help you choose. We install both types.
The process
The first job on site is protection: sheets over the floor and any furniture nearby and nothing is moved without asking you. After that, anything electrical is made safe and we start. It takes from a couple of days to around a week, depending on the system and how much of the heating changes, and we clear up before we go. For a place like Larkfield, the timing is set with you and the travel is our side of the planning.
- You tell us about the home and what you want from a heat pump.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- We explain which type of heat pump suits the home and whether a grant could apply.
- We install the heat pump and connect it up.
- After commissioning, you get the MCS certificate and a handover.
Before we arrive
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Tell us about parking and loading
- Arrange for someone to be there to let us in

Air source heat pumps around Larkfield
At about 27 miles from central London, Larkfield sits inside the area we cover across London and the South East. 6 conservation areas lie within a mile of central Larkfield. Historic England lists about 8 buildings and structures within half a mile of the centre of Larkfield, including Bradbourne House (grade I). For a heat pump, permitted development does not apply within the grounds of a listed building, and in a conservation area the outdoor unit cannot go on a wall or roof facing a road, so we check with the planning team at Tonbridge and Malling council, which usually handles Larkfield where needed.
Period properties close to Church of the Holy Trinity can suit a heat pump, though insulation and any heritage protection are checked first. Historic houses such as Starkey Castle, about 4.3 miles north, are a reminder that listed homes need consent before a heat pump goes in.

Why deal with it now?
Choosing between air-to-water and air-to-air is easier with the facts. Air-to-water heats radiators and hot water, and can attract a £7,500 grant where eligible; air-to-air heats and cools rooms, and only qualifies for £2,500 under strict conditions. We explain which makes sense for you. Booking before summer means the work in Larkfield is done before the hot weather.
What you pay reflects the actual work. That is why we look at the job first, from photos or on a survey, and the price is agreed before any work starts.
