What a heat pump looks like in Duddleswell
At about 33 miles from central London, Duddleswell sits inside the area we cover across London and the South East. VOA council tax data put about 43% of homes in and around Duddleswell before 1919, and the last census (2021) found about 87% of households in detached or semi-detached houses. In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. 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. The installer applies for the Boiler Upgrade Scheme grant, and we’re MCS certified.

How we handle air source heat pumps in Duddleswell
Hot water from an air-to-water system is stored in a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. Air-to-air systems don’t heat hot water, so you will need another way to do that. The work covers underfloor heating, homes heated by oil, LPG or gas and air-to-air heat pumps, and the jobs we see most are no space for a hot water cylinder and comparing heat pump types.
If your home in or near Duddleswell 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.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Pricing air source heat pumps in Duddleswell
We quote each job individually. This is what makes a difference:
- The type of system, from a single split to a larger system
- How easy the units are to reach
- What state the existing equipment is in
Putting several jobs into one visit can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed price.
What to send for a quote
You do not need the technical terms. It helps if you can send:
- A close-up of the unit’s label showing the model number
- The outside wall, roof or yard where the outdoor unit sits or would go
- A photo of the consumer unit with the cover closed
Here’s what helps us quote: where the property is and what kind of building it is, pictures of the rooms or units, the brand and model of anything already fitted and anything you’ve noticed, such as an error code or a noise. Once you have those, ring 07833 053749 or email us.
Duddleswell questions
Can you do air source heat pumps in Duddleswell?
We do: Duddleswell falls inside our working area. Just ring us on 07833 053749 or use the quote form with a few details.
Will you come out to Duddleswell?
Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.
How much VAT is charged on a heat pump in a home?
In residential accommodation, 0% until 31 March 2027 and 5% afterwards. The relief does not cover businesses. Please treat this as general information, not tax advice.
What does an air-to-water heat pump cost?
Air-to-water work is in the £8,000–£16,000 range (0% VAT on homes), with any grant still to come off. Where you land depends on the size of heat pump, any radiators that need changing and the hot water cylinder, and air-to-air systems are priced after a survey.
How soon will you get back to me?
On the same working day you contact us. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Will skipping a service affect the warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Either way, keep a record of every service.
Can you set up regular servicing?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
How the visit works
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. You only need to give us clear access to the units, or their planned positions, and to the fuse board. On site, the work 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. If a lane or gateway near Duddleswell is tight for a van, let us know and we will plan for it.
- First we find out about the property, the heating you have now and what you’re hoping for.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Commissioning, MCS certification and a handover of the controls finish the job.
Before we arrive
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Clear a path to the units and the space around them
- Mention any parking restrictions near the property

After we have gone

From one of our customers
“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.”
