How we price air source heat pumps
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The distance and route between the indoor and outdoor units
- Whether the existing supply is suitable
- The brand, model and parts involved
The price reflects the work, not guesswork. That is why every job is looked at first, and why the quote is fixed before any work starts.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- Any previous service or F-Gas records
- Your consumer unit or fuse board
- A close-up of the unit’s label showing the model number
If you need air source heat pumps in Southernden, give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk. Tell us what kind of property it is and what you’d like done, plus some photos if they’re to hand. We reply the same working day.
Air source heat pumps in Southernden
Heat pumps run at lower flow temperatures than most boilers, so radiators may need to be larger to give out the same heat. We check each radiator against the room’s heat loss and anything that needs changing is in the quote. Typical jobs include radiators that may be too small for a heat pump and deciding on the outdoor unit position, on hot water cylinders, air-to-water heat pumps and homes heated by oil, LPG or gas.
Older and listed homes in villages like Southernden need extra care, and permitted development doesn’t cover listed buildings, so we check consent first.
The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

What happens on the day
Think of the visit in three stages: diagnose, treat and sign off. First comes a careful look at the system or the space, then we do the work, and finally we test, record and explain. The middle part takes longest, which takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Photos of the room and the outside of the property help us plan a visit to Southernden.
- You tell us about the home and what you want from a heat pump.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- We install the heat pump and connect it up.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Preparing for the visit
- Mention any roof access, ladders or high-level work
- Dig out any previous service or F-Gas records
- Let us know where the consumer unit is
Ask for a quote
Every quote starts with a look at the job, from a site survey or, where the job is straightforward, from pictures and measurements. After that, we send a fixed price before any work starts.

Heat loss surveys
Getting the survey right avoids undersized or oversized systems and that matters for comfort and running.
Air-to-air heat pumps
Air-to-air heat pumps are now covered by permitted development rules in England, subject to conditions. Cooling-only units are not included, so check with the council.
Southernden: your questions answered
Is the heat pump grant available in Southernden?
Southernden is in England, where the Boiler Upgrade Scheme runs. 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. The installer applies, and we’re MCS certified.
Will a heat pump in Southernden need planning permission?
The answer turns on the property and where the outdoor unit would sit. Historic England lists about 4 buildings and structures within half a mile of the centre of Southernden. 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 Southernden, typically Maidstone council).
Do you work in Southernden?
Yes. We work across Greater London, Surrey, Kent, East and West Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, Southernden included.
Do you offer maintenance contracts?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is recorded, with F-Gas records where refrigerant work is involved.
Which accreditations do you hold?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Southernden and across Kent. Tell us who should receive the paperwork.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine, on all the main brands. Send us the make and model, and any records you have.
Air source heat pumps around Southernden
The Valuation Office Agency’s council tax figures show about 32% of homes across Southernden and its surrounding area were built in 2000 or later, and about 74% of households live in detached or semi-detached houses, according to the last census (2021). 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.
A heat loss calculation decides the size of heat pump your home needs. With Leeds Castle about 4.8 miles north, it’s worth asking whether your own home is listed before planning a heat pump.

Safe owner checks
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
What a customer said
“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.”
