How we handle air source heat pumps in Farthing Green
A heat pump takes heat from the outside air and moves it into your home with electricity running the compressor and fans. The technology is close to air conditioning, which is why we install both and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. If you are dealing with no space for a hot water cylinder and questions about the Boiler Upgrade Scheme, we can sort it out.
If your home in or near Farthing Green is heated by oil, LPG or electric heaters with no mains gas, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027, on top of the £7,500.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

Farthing Green: your questions answered
Will a heat pump in Farthing Green need planning permission?
There’s no single answer: the building and the outdoor unit position decide it. The half-mile around the middle of Farthing Green holds about 7 listed buildings and structures. 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 the local planning authority (for Farthing Green, normally Maidstone council).
Is Farthing Green within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
What does an air-to-water heat pump cost?
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes) before the grant. The Boiler Upgrade Scheme offers £7,500 to eligible homes in England and Wales, and we confirm eligibility before you commit.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
When will I hear back?
You will hear from us the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Why does F-Gas certification matter?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before booking and we will gladly show you ours.
Do you look at the job first?
Yes. We always look before we price, either on a site survey or from photos and details for simple jobs. A fixed-price quote follows.
How we price air source heat pumps
The diagnosis comes before the price. We look at:
- The size of the job
- Access, including height, roofs and ladders
- How far the pipework has to run, and where
The pipe route, the height of the units and how we reach them all affect the cost. We take each of them into account and give you a fixed price before we start.
What to send for a quote
There’s no need for technical detail. It helps if you can send:
- Where the outdoor unit is, or where you’d like it
- A close-up of the unit’s label showing the model number
- A short video of any fault, such as a noise or a flashing light
If you need air source heat pumps in Farthing Green, ring us on 07833 053749. Tell us what kind of property it is and what you’d like done, plus some pictures if they’re to hand. We reply the same working day.
Signs you need air source heat pumps in Farthing Green
When a home is being extended or renovated, it’s a good moment to look at heat pumps. Pipework, radiators and space for a cylinder are easier to plan while work is going on.
These are the situations we see most often:
- Checking whether planning permission is needed
- Deciding on the outdoor unit position
- Moving away from fossil-fuel heating
Every heat pump design starts with a room-by-room heat loss calculation.
Comparing quotes
- Whether extra work needs your approval first
- Which brand and model they’re proposing, and why
- Whether they hold F-Gas company certification, not just individual qualifications
System by system
The Boiler Upgrade Scheme
There’s one grant per property, and you cannot get a grant to replace a low-carbon system. Hybrids are excluded.
Heat loss surveys
Getting the survey right avoids undersized or oversized systems, and both cause problems.
Air source heat pumps in Farthing Green: the local picture
About 32% of homes in and around Farthing Green have been built since 2000, according to Valuation Office Agency council tax records, and about 74% of households live in detached or semi-detached houses, according to the last census (2021). Newer homes typically lose less heat, which tends to suit a heat pump well. Houses typically have space for an outdoor unit and a hot water cylinder.
With Stoneacre about 4.4 miles north, it’s worth asking whether your own home is listed before planning a heat pump.

What else we do in Farthing Green
How the visit works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. On site, it takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Work in Farthing Green is booked in advance at a time that suits you.
- It begins with your house and the heating it relies on now.
- We measure heat loss for every room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Then it’s fitted, commissioned and registered with MCS.
Getting ready for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Clear access to the fuse board
- Tell us about any building rules, permits or sign-in
