What the work involves, system by system
VAT on heat pumps
Heat pumps in homes carry 0% VAT until 31 March 2027, and 5% after that, under HMRC Notice 708/6. It doesn’t apply to businesses.
Air-to-water heat pumps
Air-to-water systems work at lower temperatures than boilers, which is why radiator sizing is part of the survey.
Air source heat pumps for homes and businesses in St George's Fields
Air source heat pumps collect heat from outdoor air and bring it inside with electricity running the compressor and fans. The technology is close to air conditioning, which is why we install both and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. The work covers homes heated by oil, LPG or gas, air-to-air heat pumps and radiator systems, and people most often call us about questions about listed buildings or conservation areas and questions about the Boiler Upgrade Scheme.
Homes in St George's Fields are often flats and terraces, where outside space is limited, which affects which heat pump suits. Air-to-water needs room for the outdoor unit and usually a cylinder, while air-to-air units take less room.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

Air source heat pumps in St George's Fields: the local picture
VOA council tax data show about 43% of homes across St George's Fields and its surrounding area were built in 2000 or later, and about 90% of households live in flats, according to the last census (2021). Newer homes normally lose less heat, which tends to suit a heat pump well. For flats, the first questions are where an outdoor unit could go, whether a cylinder fits and what the lease allows. For a London home, the outdoor unit position and the MCS noise check need careful planning.
Older homes near Former Church of St Jude may need extra checks for planning and heat loss before a heat pump is designed. Homeowners near Elephant & Castle station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that.

Questions from St George's Fields
Can I have air conditioning in a flat in St George's Fields?
Often, yes, but the lease and the freeholder normally have a say. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Does the Boiler Upgrade Scheme cover homes in St George's Fields?
St George's Fields 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. As an MCS certified installer, we apply for it on your behalf.
Should I choose air-to-water or air-to-air?
The right choice depends on the property and what you need. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions. We explain the options after the survey.
Will skipping a service affect the warranty?
It can, for some brands. Send us the make and model and we’ll tell you what the manufacturer expects and stick to the interval they set.
Will my radiators work with a heat pump?
That depends on the room’s heat loss and the radiator’s size. We check them all during the survey and the quote shows what’s needed.
How long does a heat pump installation take?
It 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. The cylinder, the radiators and the pipework make the biggest difference, and we confirm the timing with your quote.
Can I do the refrigerant work myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.

What affects the quote in St George's Fields

- Whether it’s a one-off job or part of a maintenance contract
- The electrical supply and whether a new circuit is needed
- The number of rooms, units or zones
A single unit or a whole estate, the quote is built the same way: what needs doing, how we get to it and what it needs. The price is fixed before any work starts, and the quote sets out the VAT.
Before you get in touch
Photos and a few facts are often enough to price a simple job. Send what you can of the following:
- The outdoor side of the property, including any roof or flat area
- The rating plate or label on any existing unit
- The fuse board and where it is in the property
Published ranges are a starting point; the quote is built on your property, because every property is different. Once we have looked at the job, from photos or on a survey, you get a fixed price. To start, give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk.

“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.”
