Air source heat pumps for homes and businesses in Knockholt Pound
Hot water from an air-to-water system is stored in a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. With air-to-air, hot water has to come from something else. The work covers homes heated by oil, LPG or gas, hot water cylinders and air-to-air heat pumps, and the jobs we see most are radiators that may be too small for a heat pump and comparing heat pump types.
If your home in or near Knockholt Pound 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.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual, because it helps with any later warranty question.

What the work involves, system by system
Heat loss surveys
The survey works out the heat needed room by room. It’s the basis for sizing the heat pump and the radiators.
Air-to-air heat pumps
Since 2025, air-to-air heat pumps can also be permitted development in England, subject to the conditions. A unit used solely for cooling isn’t covered, so check with the council.
Signs you need air source heat pumps in Knockholt Pound
People also ask about air-to-air heat pumps because they heat and cool. They warm rooms directly through indoor units and switch to cooling in warm weather. Whether a grant applies depends on the scheme conditions.
Customers usually contact us when they notice something like this:
- Plans to switch to electric heating with a heat pump
- Questions about the Boiler Upgrade Scheme
- Questions about where the outdoor unit can go
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
- Whether the quote shows VAT clearly
- Whether they hold F-Gas company certification, not just individual qualifications
- Whether extra work needs your approval first

Your questions about air source heat pumps in Knockholt Pound
Can I get the Boiler Upgrade Scheme grant in Knockholt Pound?
Yes, if the home and the heat pump meet the scheme’s rules: Knockholt Pound is in England, where it applies. The amount depends on the type of heat pump, and the survey confirms which applies. We hold MCS certification, so the application is ours to make for you.
Will a heat pump in Knockholt Pound need planning permission?
That depends on the building and where the outdoor unit goes. A conservation area takes in the middle of Knockholt Pound. 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 planning department at Sevenoaks council, normally the authority for Knockholt Pound.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up, with F-Gas records where refrigerant work is involved.
What does F-Gas certified mean?
Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.
Do you provide F-Gas records?
Yes. It’s your proof of what was done: the date, the work, and any refrigerant added or recovered.
Is Knockholt Pound in your area?
Yes. Knockholt Pound is part of the area we cover, within the South East and London area we cover. Our base is in East Grinstead, West Sussex.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us in Knockholt Pound and across Kent. Let us know who the records should go to.
How the visit works
We book the visit for a day and time that suit you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the pictures you sent. If something is different, we talk it through with you before carrying on. After that, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Rural lanes and tight entrances are worth mentioning before a visit to Knockholt Pound.
- We start with your plans and the property.
- 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.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Getting ready for the visit
- Unlock any gate, garage or side passage we need
- Let us know if the building has a permit or sign-in process
- Make sure we can reach the consumer unit or fuse board

Quotes don’t take long. Send a few details and photos, and we reply the same working day. If we need to see the property first, we book a survey at a time that works for you.
