About our air source heat pumps in Gravel Castle
A £2,500 grant is available for some air-to-air heat pumps, with conditions. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home; adding it alongside a boiler does not qualify. The work covers air-to-air heat pumps, underfloor heating and air-to-water heat pumps, and the jobs we see most are checking emitters for a heat pump and wanting to stop using oil, LPG or gas for heating.
Homes around Gravel Castle normally have room outside for a heat pump, so the design focuses on heat loss and radiators.
We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

What a heat pump looks like in Gravel Castle
The Barham Conservation Area is within about a third of a mile of the centre of Gravel Castle. There are 6 conservation areas within a mile of the centre of Gravel Castle. Listed buildings are part of the picture here: about 43 within half a mile of the centre, such as Church of St John the Baptist (grade I). Where a home is affected, the outdoor unit position is settled with the local planning authority (typically Canterbury City council) before the heat pump design is finished. About 35% of homes in Gravel Castle and the neighbourhoods around it have been built since 2000, according to the Valuation Office Agency’s council tax figures, and the 2021 Census found about 65% of households in detached or semi-detached houses. Lower heat loss in recent homes often means a smaller heat pump and fewer radiator changes. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.
Older homes near Church of St John the Baptist may need extra checks for planning and heat loss before a heat pump is designed. With Goodnestone Park about 3.8 miles north-east, it’s worth asking whether your own home is listed before planning a heat pump.

Different systems, different jobs
Hot water cylinders
Hot water from an air-to-water system is stored in a cylinder. The survey looks at where it can go, especially if you have a combi boiler.
Outdoor unit position and planning
Under permitted development, the outdoor unit must be 1.5 m³ or less and must meet MCS 020(a) and not be used solely for cooling. Listed building curtilages are excluded.
For landlords and property managers
Whether it’s one property or many, you get the same standard: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
Bigger systems bring extra duties: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We can arrange it, prepare the system for it and fix what it finds.
What we do, step by step
We book the visit for a day and time that suit you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your photos or the details you gave us. Anything unexpected is raised with you before we go further. From there, the work takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. Work in Gravel Castle is booked in advance at a time that suits you.

Gravel Castle: your questions answered
Is the heat pump grant available in Gravel Castle?
Yes, if the home and the heat pump meet the scheme’s rules: Gravel Castle is in England, where it applies. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. The installer applies, and we’re MCS certified.
Will you come out to Gravel Castle?
We do. Villages and hamlets get the same service as the bigger towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you work on commercial properties?
Yes. From one rented home to commercial buildings, the approach is the same: a look first, a fixed-price quote and written records.
Do you offer emergency call-outs?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we will tell you what to do first.
Are my radiators big enough for a heat pump?
That depends on the room’s heat loss and the radiator’s size. The survey compares each radiator with the room’s needs and the quote shows what’s needed.
Should I choose air-to-water or air-to-air?
Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. Air-to-air does not heat hot water, and we explain which suits your home.
Do I need planning permission for a heat pump?
It depends on the property and where the unit goes. Flats have different limits, conservation areas have extra conditions, and an Article 4 direction can remove the rights, so we check during the survey.
What affects the cost of air source heat pumps
Typical ranges are on our prices page, but every job is priced on its own. The quote depends on:
- The type of system, from a single split to a larger system
- Whether we need access equipment for high-level work
- The brand, model and parts involved
Homes, offices, shops and public buildings are all priced the same way: the equipment, the access, the work involved and the time it takes. Ask for a fixed-price quote and we will explain each part.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- The paperwork from the last service, if you have it
- Photos showing the indoor unit and the space around it
- The postcode and whether it’s a home, flat or business
