Mottisfont air source heat pumps
For MCS certified installation of air source heat pumps for heating and hot water, with the Boiler Upgrade Scheme grant applied for in Mottisfont, one call is all it takes: diagnosis, fixed price, work and sign-off. F-Gas certified, NICEIC approved and Checkatrade members.
- Deciding on the outdoor unit position
- Questions about the Boiler Upgrade Scheme
- Wanting to stop using oil, LPG or gas for heating
How it works
If the system has to be off for part of the visit, we tell you before work begins, so you can plan around it. For businesses, we can usually work room by room or zone by zone. On site, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. If a lane or gateway near Mottisfont is tight for a van, let us know and we will plan for it.
- First, a chat about the property and your goals for the heating.
- 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.
- Installation follows on the agreed dates.
- After commissioning, you get the MCS certificate and a handover.
Preparing for the visit
- Dig out any previous service or F-Gas records
- Make sure we can reach the consumer unit or fuse board
- Let us know if the units are on a roof, a high wall or in a locked area

Air source heat pumps in Mottisfont, done properly
Heat pumps run at lower flow temperatures than most boilers which means some radiators may need upsizing. The survey shows which rooms are fine and which need changes, and the quote sets it out. If you are dealing with deciding on the outdoor unit position and checking eligibility for a heat pump grant, we can help.
Homes around Mottisfont normally have room outside for a heat pump, so the design focuses on heat loss and radiators.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

Homes in Mottisfont and heat pumps
The Valuation Office Agency’s council tax figures put about 37% of homes in and around Mottisfont before 1919, and Census 2021 figures found about 83% of households in detached or semi-detached houses. 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. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.
If your home is listed, like Mottisfont Abbey about 0.2 miles north-east, listed building consent comes before any heat pump work.

Owner checks or an engineer?
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.
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.
Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Keep to regular servicing
- Store the MCS certificate and warranty documents together
- Clear leaves and debris from the outdoor unit
Once commissioned, we register the installation with MCS and give you the certificate. Keep it with the manufacturer’s paperwork for future reference.
Let the heat pump run steadily rather than switching it on and off, using the settings agreed at handover.
Questions from Mottisfont
Is a heat pump in Mottisfont permitted development?
It depends on the property. Central Mottisfont sits inside the Mottisfont Conservation Area. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit can’t face a road. Where necessary, we check with the local planning authority (for Mottisfont, normally Test Valley council).
Is the heat pump grant available in Mottisfont?
Yes, the scheme covers homes in England, including Mottisfont, if they qualify. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and isn’t an add-on to a boiler. As an MCS certified installer, we apply for it on your behalf.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We are happy to quote for the full job, supply to commissioning.
Do I need new radiators for a heat pump?
That depends on the room’s heat loss and the radiator’s size. The survey compares each radiator with the room’s needs and the quote shows what’s needed.
Do I get paperwork after the visit?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re also Checkatrade members.
Does servicing affect my warranty?
It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we’ll explain them and stick to the interval they set.
Do you need air source heat pumps in Mottisfont?
Extensions, renovations and loft conversions are a natural time to rethink the heating. It’s simpler to plan radiators, pipework and a cylinder while the builders are in.
Reasons to give us a call include:
- Working out where a cylinder could go
- Finding a place for the outdoor unit
- Comparing heat pump types
Homeowners near Mottisfont & Dunbridge station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that.
What your quote should include
- If the quote is based on a survey, photos or a diagnosis
- What records you get at the end
- Whether they hold F-Gas company certification, not just individual qualifications
