How we handle air source heat pumps in Lower Twydall
Air source heat pumps collect heat from outdoor air and bring it inside, using electricity to drive the process. 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 hot water cylinders, homes heated by oil, LPG or gas and underfloor heating, and the jobs we see most are deciding which kind of heat pump suits the home and questions about the Boiler Upgrade Scheme.
Homes around Lower Twydall typically have room outside for a heat pump, so the design focuses on heat loss and radiators.
Each manufacturer sets its own warranty period. For example, 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.

Heat pumps in Lower Twydall: local notes
Lower Twydall is within about 1 mile of the coast. Salt air is hard on outdoor units, so a heat pump near the sea needs a sensible position and regular checks, and some models offer corrosion protection for coastal sites. The Valuation Office Agency’s council tax figures date about 68% of homes in the Lower Twydall area to the post-war years, 1945 to 1972, and about 38% of households live in terraced houses, according to the 2021 Census. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Terraced houses share walls with neighbours, which helps, but the outdoor unit position needs care with noise next door.
Historic houses such as Restoration House, about 3.7 miles west, are a reminder that listed homes need consent before a heat pump goes in.

Do you need air source heat pumps in Lower Twydall?
Many enquiries start with a question about the Boiler Upgrade Scheme. Eligibility depends on the property, the system and the scheme rules and we confirm it before you go ahead.
These are the situations we see most often:
- A boiler that’s getting old
- Deciding on the outdoor unit position
- Not knowing whether a grant applies
Older homes near Holy Trinity Church may need extra checks for planning and heat loss before a heat pump is designed.
Before booking anyone
- Why the equipment they’re quoting suits the job
- If the figure could change on the day
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
When it’s something else
Air source heat pumps can’t fix everything, and we’d rather say so up front. It won’t put right:
- Insulation work, such as loft or cavity wall insulation
- Getting planning permission or listed building consent on your behalf
- Any gas work on the existing boiler
If in doubt, ring us on 07833 053749 or write to us at info@aircondoctor.co.uk and we will say what we think before you book.
What the work covers
- Underfloor heating
- Homes heated by oil, LPG or gas
- Air-to-air heat pumps
- Air-to-water heat pumps
- Radiator systems
- Hot water cylinders
How it works
Protection comes first: sheets over the floor and any furniture nearby and nothing is moved without asking you. Then the electrics are made safe and the work begins. It takes a few days for most air-to-water installations, with air-to-air systems often quicker, and we clear up before we go. Visits to Lower Twydall are agreed with you in advance and planned so the job can be finished in one trip where possible.
- First we find out about the property, the heating you have now and what you are hoping for.
- 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.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
How to prepare
- Let us know where we can park and unload
- Unlock any gate, garage or side passage we need
- Find the manual or the paperwork for the system, if you have it

Related advice
Your questions about air source heat pumps in Lower Twydall
Do I need planning permission for a heat pump in Lower Twydall?
It comes down to the building and the spot chosen for the outdoor unit. There’s a conservation area, the Lower Twydall Conservation Area, close to central Lower Twydall. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with Medway council, which is normally the planning authority for Lower Twydall first.
Is the coast a problem for outdoor units in Lower Twydall?
It can, as Lower Twydall is within about 1 mile of the sea, where salt in the air is hard on coils and fixings. We site outdoor units out of the worst of the sea wind where possible and can suggest models with corrosion protection where the manufacturer offers it.
Does servicing affect my warranty?
It can, for some brands. Send us the make and model and we will tell you what the manufacturer expects, and book the service at the interval they recommend.
Will my home qualify for the Boiler Upgrade Scheme?
Possibly. In England and Wales it pays £7,500 for an eligible air-to-water or ground source heat pump, and £2,500 for air-to-air under tighter rules. Homes heated by oil or LPG with no mains gas can get an extra £1,500 towards an air source or ground source heat pump until March 2027. We check your home against the rules at the survey.
Do you protect the property while you work?
Floors and furniture near the work are covered with dust sheets before work begins, and the area is kept tidy throughout. At the end, we clear up and show you what we’ve done.
Will you work on another installer’s system?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
Should I choose air-to-water or air-to-air?
It depends on your home, your heating and whether you want cooling. The grant is £7,500 for eligible air-to-water systems and £2,500 for air-to-air in limited cases, and we set out the options after the survey.
