Air source heat pumps in Down Street
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. 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. We are often asked to deal with not knowing whether a grant applies and questions about listed buildings or conservation areas, on air-to-air heat pumps, underfloor heating and hot water cylinders.
Homes around Down Street typically have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s 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.

When to call us in Down Street
Air-to-air systems interest people who want cooling in summer as well as heating. They warm rooms directly through indoor units and switch to cooling in warm weather. Whether a grant applies depends on the scheme conditions.
Most people get in touch when they notice something like this:
- Working out whether radiators need upsizing
- Finding a place for the outdoor unit
- Wanting to stop using oil, LPG or gas for heating
Period properties close to The Parish Church of St Andrew and St Mary can suit a heat pump, though insulation and any heritage protection are checked first.

Down Street: your questions answered
Is Down Street within the area you cover?
Yes, and the size of the place makes no difference to how we work. Send a few details and photos, and we reply the same working day.
Can I fit a heat pump in Down Street without planning permission?
The answer turns on the property and where the outdoor unit would sit. The half-mile around the middle of Down Street holds about 5 listed buildings and structures. 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 cannot face a road. Where necessary, we check with the planning department at Wealden council, typically the authority for Down Street.
Do you work on systems someone else installed?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Tell us the make and model and send any paperwork you have.
Do you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and tell you why.
Is there a Boiler Upgrade Scheme grant for air-to-air?
Only in limited cases, with a grant of £2,500. The system must replace the existing fossil-fuel heating, meet the home’s full heating demand, be installed by an MCS certified installer and be in a home.
Who has to arrange F-Gas leak checks?
Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Do you survey before quoting?
Yes. For simple jobs, pictures and a few details can be enough, while larger systems and faults that need testing are seen on site.
The process
Testing is the last part of the visit wherever the system can be switched on. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Seeing the property in photos first means the trip to Down Street can be planned properly.
- We talk through your home, your current heating and what you want from a heat pump.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
How to prepare
- Keep pets out of the rooms we’re working in
- Arrange for someone to be there to let us in
- Clear the space around the indoor unit, or where it will go
Getting a quote
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and many jobs can be priced from that.

Heat pumps in Down Street: local notes
About 42% of homes in the Down Street area date from 1945 to 1972, according to Valuation Office Agency council tax records, and about 62% of households live in detached or semi-detached houses, according to the last census (2021). Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Houses typically have space for an outdoor unit and a hot water cylinder.
Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.

Before you call an engineer
On air conditioning, the filters in the indoor unit are usually the one part owners can clean, if the manual says so. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and phone 07833 053749 or email us.
