Air source heat pumps around How Green
Central How Green is inside a conservation area. About 11 listed entries lie within half a mile of central How Green, Dairy Cottage at Hever Stud Farm (grade II) among them. For a heat pump, permitted development does not apply within the grounds of a listed building, and in a conservation area the outdoor unit can’t go on a wall or roof facing a road, so we check with the planning team at Sevenoaks council, which normally handles How Green where necessary. About 23 miles out from central London, How Green is part of the South East area we work across.
Historic houses such as Hever Castle, about 0.7 miles south, are a reminder that listed homes need consent before a heat pump goes in. Older homes near Church of St Peter may need extra checks for planning and heat loss before a heat pump is designed.

Air source heat pumps in How Green, done properly
Air source heat pumps collect heat from outdoor air and bring it inside, using electricity to drive the process. The technology is close to air conditioning, which is why we install both, and air-to-air heat pumps are sometimes simply called air conditioning. If the problem is checking eligibility for a heat pump grant and a boiler that’s getting old, we can sort it out.
In a place like How Green, some homes are listed, because permitted development doesn’t apply within the grounds of a listed building, so consent comes first.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

Pricing air source heat pumps in How Green
The diagnosis comes before the price. The main factors are:
- Access, including height, roofs and ladders
- The size of the job
- What we find on the survey or diagnosis
Putting the work off seldom saves money. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you are not sure what’s needed, give us a ring on 07833 053749 or drop us a line and we’ll give you an honest view and a fixed price.
Helping us quote
You do not need the technical terms. It helps if you can send:
- The address and the type of property
- The remote or wall controller showing any error
- The rating plate or label on any existing unit
Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. Once we have looked at the job, from pictures or on a survey, you get a fixed price. To get going, call 07833 053749 or send an email.
What happens on the day
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we’ve done and answer any questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes from a couple of days to around a week, depending on the system and how much of the heating changes. For a village like How Green, tell us about narrow lanes, gates and parking when you book.
- First, a chat about the property and your goals for the heating.
- 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.
How to prepare
- Tell us about any building rules, permits or sign-in
- Clear a path to the units and the space around them
- Tell us about access, such as roof hatches, high walls or locked plant areas
Ask for a quote
Getting a quote is straightforward. Send a few details and pictures, and we reply the same working day. Where a survey is needed, we arrange a time that suits you.
Advice
How Green questions
Do you cover smaller places like How Green?
We do. Villages and hamlets get the same service as the bigger towns. A few photos and the postcode are enough to get things started.
Can I get the Boiler Upgrade Scheme grant in How Green?
How Green is covered, as the scheme runs across England and Wales. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. You do not apply yourself: the MCS certified installer does, which is us.
Who is responsible for leak checks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we’re Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Will I get records for the system?
Yes. You get a written record of each visit, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
How quickly will you reply?
You’ll hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
Will you make a mess?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
Before you call an engineer
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
Why deal with it now?
Replacing a boiler in a hurry when it breaks leaves little time to consider a heat pump. Planning ahead gives time for the heat loss survey, the design and the grant application while the old heating still works. Planning ahead for a job in How Green means we can bring everything needed.
Putting several jobs into one visit can make for a more efficient booking. Mention every unit or room you need covered, and you will get one fixed price.
