Air source heat pumps around Longfield
Valuation Office Agency council tax records date about 45% of homes in and around Longfield to the post-war years, 1945 to 1972, and Census 2021 figures found about 82% of households in detached or semi-detached houses. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these. At about 19 miles from central London, Longfield sits inside the area we cover across London and the South East.
If your home is one of the older properties near Church of Saint Mary Magdalene, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. Cobham College lies about 4 miles east. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.

Air source heat pumps in Longfield
A £2,500 grant is available for some air-to-air heat pumps, with conditions. 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; adding it alongside a boiler does not qualify. If the problem is deciding on the outdoor unit position and not knowing whether a grant applies, we can help.
If your home in or near Longfield is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump, on top of the £7,500.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Common questions in Longfield
Is a heat pump in Longfield permitted development?
That depends on the building and where the outdoor unit goes. The half-mile around the middle of Longfield holds about 1 listed buildings and structures. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the local planning authority (for Longfield, usually Dartford council).
Is the heat pump grant available in Longfield?
Yes, the scheme covers homes in England, including Longfield, if they qualify. 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. You do not apply yourself: the MCS certified installer does, which is us.
Does servicing affect my warranty?
For some brands, yes. Read the manufacturer’s terms, or send us the make and model and we’ll explain them and stick to the interval they set.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
Do you work in Longfield?
Yes. We work in Longfield and the rest of Kent, as part of our area across London and the South East. To book, phone us on 07833 053749 or drop us a line.
Is the equipment covered by a warranty?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition, so keep your service records.
Which manufacturers do you install and repair?
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 explain why.
What affects the quote in Longfield
Jobs vary more than people expect. The main factors:
- Whether we need access equipment for high-level work
- How many units are involved
- What kind of system it is
Whatever the property, the quote works the same way: what’s needed, how we reach it, the parts and the labour. Call for a fixed-price quote and we’ll explain each part.
What we need to know
Before you ask for a quote, gather:
- Photos showing the indoor unit and the space around it
- Any error code or flashing light on the display
- The outside wall, roof or yard where the outdoor unit sits or would go
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price so you know the cost before we begin.
What the work involves, system by system
Hot water cylinders
Existing cylinders may not be suitable for a heat pump, and we explain whether yours can stay.
Outdoor unit position and planning
Flats and blocks of flats have different limits, and Article 4 directions can remove rights. Listed building consent is a separate matter and we check what applies to you.
What we do, step by step
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we’ve done and answer any questions, and anything that needs attention later is pointed out. All told, the work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. A few pictures help us make the most of a visit to Longfield.
- We talk through your home, your current heating and what you want from a heat pump.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Preparing for the visit
- Have the make and model of any existing unit to hand
- Let us know if the building has a permit or sign-in process
- Arrange for someone to be there to let us in
Ask for a quote
To help us quote: the address and the type of property, pictures of the rooms or units, the make and model of any existing system and any symptoms, from error codes to drips. Once you have those, call us on 07833 053749 or write to us at info@aircondoctor.co.uk.
