Air source heat pumps for homes and businesses in Blackheath
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. The system must replace the existing fossil-fuel heating and meet the home’s full heating demand, it must be installed by an MCS certified installer, and it must be in a home, so an add-on next to a boiler is not eligible. Common call-outs are for questions about where the outdoor unit can go and not knowing whether a grant applies, across hot water cylinders, underfloor heating and radiator systems.
In a flat in Blackheath, the lease and the freeholder usually decide where a heat pump can go. The planning rules for flats are stricter than for houses, so we check the position before we design.
Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

Owner checks or an engineer?
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.

What a heat pump looks like in Blackheath
About 42% of homes in the Blackheath area were built before 1919, according to Valuation Office Agency council tax records, and Census 2021 figures found about 66% of households live in flats. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. Flats are often harder for air-to-water systems, so we look at whether air-to-air suits better. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
If you live near Blackheath station, the survey compares air-to-water and air-to-air for your home before anything is quoted. Live in one of the older houses around Church of All Saints? Expect the survey to look closely at heat loss and at the building’s planning status.

Different systems, different jobs
Hot water cylinders
Existing cylinders may not be suitable for a heat pump and we tell you if it needs replacing.
Heat loss surveys
Without a proper survey, a heat pump can be too big or too small and that matters for comfort and running.
How it works
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and the rest is down to us. At the end, we tidy up and run through the work with you. Before a visit in Blackheath, we ask where the van can stop and how we reach the outdoor unit.
- We start with your plans and the property.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- We recommend air-to-water or air-to-air and check the grant position.
- We install the heat pump and connect it up.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Getting ready for the visit
- Arrange for someone to be there to let us in
- Let us know if the units are on a roof, a high wall or in a locked area
- Find the manual or the paperwork for the system, if you have it
Getting a price
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your photos and details. Then you get a fixed price so you know the cost before we begin.

Your questions about air source heat pumps in Blackheath
Do I need permission to put air conditioning in my flat in Blackheath?
Typically, yes, though leaseholders normally need the freeholder’s agreement. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Do I need planning permission for a heat pump in Blackheath?
That depends on the building and where the outdoor unit goes. The centre of Blackheath is in the Blackheath 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 don’t 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 the local planning authority (for Blackheath, typically Lewisham council).
Do you work in Blackheath?
Yes. Our engineers work in Blackheath, within the South East and London area we cover. We are based in East Grinstead, West Sussex.
What does an air-to-water heat pump cost?
For air-to-water, the price is £8,000–£16,000 (0% VAT on homes) before any grant. Eligible homes in England and Wales can get £7,500 through the Boiler Upgrade Scheme though not every home qualifies.
How quickly will you reply?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Who is responsible for leak checks?
Responsibility is shared between the operator, normally 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.
Can I do any of the installation myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is a legal requirement, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
From one of our customers
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
