Air source heat pumps in Sissinghurst, done properly
In England, an air source heat pump on a house can often go in under permitted development rights. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We look at the planning position for your home during the survey. The work covers underfloor heating, hot water cylinders and air-to-water heat pumps, and common reasons people get in touch are questions about where the outdoor unit can go and no space for a hot water cylinder.
Older and listed homes in villages like Sissinghurst need extra care, because permitted development doesn’t apply within the grounds of a listed building, so consent comes first.
Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. Keep it with the system’s paperwork, because it helps with any later warranty question.

Managing agents and facilities teams in Sissinghurst
If you look after several properties, we can quote and plan the work across all of them. Every address has its own paperwork, so the files stay tidy.
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We are happy to deal with either side, and the paperwork can go to both.
Air source heat pumps in Sissinghurst: the local picture
Valuation Office Agency council tax records put about 35% of homes in the Sissinghurst area before 1919, and Census 2021 figures found about 71% of households in detached or semi-detached houses. Period properties can still suit a heat pump, but the design has to start from accurate heat loss figures. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
If your home is one of the older properties near Church of the Holy Trinity, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.

Sissinghurst questions
Is planning permission needed for a heat pump in Sissinghurst?
That depends on the building and where the outdoor unit goes. Central Sissinghurst sits inside a conservation area. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask Tunbridge Wells council, which is typically the planning authority for Sissinghurst.
Can I get the Boiler Upgrade Scheme grant in Sissinghurst?
Sissinghurst is covered, as the scheme runs across England and Wales. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. We hold MCS certification, so the application is ours to make for you.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.
Will I get records for the system?
Yes. Every visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. Keep them with the manual and the warranty documents.
Do you offer emergency call-outs?
Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will agree what happens next.
Is there a survey before the work?
Yes. Every job is looked at first, either on a site survey or from pictures and details for simple jobs. A fixed-price quote follows.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before you book anyone and we will gladly show you ours.
How we price air source heat pumps
The quote reflects the job in front of us. We consider:
- The equipment or parts the job needs
- The pipe route between the units
- The electrical supply and whether a new circuit is needed
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 any work starts, so you know where you stand.
What to send for a quote
Good pictures often save a visit. Try to include:
- A few photos of the room and the wall the unit is on, or will go on
- The address and the type of property
- Your installation or service records
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, ring us on 07833 053749 or use the quote form.
From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
