Air source heat pumps for homes and businesses in Knockholt
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. In England and Wales, the Boiler Upgrade Scheme offers a £7,500 grant towards an eligible air-to-water installation, and as the installer we apply for it on your behalf. Not every home qualifies, so we check eligibility before you commit. Typical jobs include checking eligibility for a heat pump grant and questions about where the outdoor unit can go, across homes heated by oil, LPG or gas, radiator systems and air-to-air heat pumps.
Space for an outdoor unit is rarely an issue near Knockholt, so the design comes down to heat loss, radiators and hot water.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

Common questions in Knockholt
Do you cover smaller places like Knockholt?
Yes. Knockholt is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is a heat pump in Knockholt permitted development?
It depends on the property. A conservation area takes in the middle of Knockholt. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the local planning authority (for Knockholt, typically Sevenoaks council).
How much time does a heat pump install need?
A typical installation takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. We plan the work so you’re without heating for as little time as possible and agreed before any work starts.
Will you make a mess?
We start with protection: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
Which manufacturers do you install and repair?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Is there a survey before the work?
Yes. Every job is looked at first, either on a site survey or from photos and details for simple jobs. A fixed-price quote follows.
Can I do any of the installation myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We are happy to quote for the full job, supply to commissioning.
What we do, step by step
The visit goes in the diary at a time that works for you, and we let you know if plans need to move. On arrival, the engineer compares the job with the survey, your photos or the details you gave us. If something is different, we talk it through with you before carrying on. After that, it takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. A note on how to find the property and where to park makes a visit to Knockholt easier.
- 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.
- The system is installed and connected to the controls.
- We commission it, complete the MCS certificate and show you how to use it.
Getting ready for the visit
- Clear the space around the indoor unit, or where it will go
- Mention any parking restrictions near the property
- Let us know where the consumer unit is
How to get a quote
Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from pictures and measurements. Then you get a fixed price so you know the cost before we begin.

Fixed-price quotes for air source heat pumps in Knockholt
We quote each job individually. This is what makes a difference:
- The electrical supply and whether a new circuit is needed
- Whether it’s a one-off job or part of a maintenance contract
- The distance and route between the indoor and outdoor units
The cost depends on the system and the number of rooms or units, how easy the units are to reach and what the work involves. You get a fixed price before work begins, so there are no surprises.
Helping us quote
Simple jobs can often be priced from photos and some basics. Send what you can of the following:
- Any previous service or F-Gas records
- Where the outdoor unit is, or where you’d like it
- The make and model of the system, from the label
Need a price for air source heat pumps? Please phone 07833 053749 or email us and tell us about the job. We’ll explain what we’d recommend and why, then send a fixed-price quote before anything is booked.
Landlords, agents and facilities managers
From a single flat to a whole estate, the approach is the same: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
Managing agents often deal with us directly. Tell us the property, the work and the access arrangements and we’ll come back with a fixed-price quote.
Common problems we fix in Knockholt
For homes with no mains gas, heated by oil or LPG, a heat pump is well worth considering. The Boiler Upgrade Scheme includes an extra £1,500, until March 2027, for air source or ground source heat pumps in homes heated by oil or LPG with no mains gas, subject to the scheme rules.
These are the situations we see most often:
- Radiators that may be too small for a heat pump
- An oil, LPG or gas boiler near the end of its life
- Deciding which kind of heat pump suits the home
If your home is one of the older properties near St Katharine's Church, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
What your quote should include
- How VAT is shown, and which rate applies
- If the figure could change on the day
- Whether the company is F-Gas certified, and whether you can check it
