Looking after it afterwards
Looking after the system is mostly common sense. Our tips:
- Keep the outdoor unit clear all year
- Check eligibility for the Boiler Upgrade Scheme early
- Seal draughts where you can
If anything does not seem right after installation, phone 07833 053749, or email if that’s easier and we will talk it through. Annual servicing helps keep the system working well.
A well-insulated home helps a heat pump because it reduces the heat the system needs to supply.
Air source heat pumps in Long Ditton, done properly
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. The Boiler Upgrade Scheme can provide £7,500 towards an eligible air-to-water system in England and Wales, and as the installer we apply for it on your behalf. Eligibility depends on the property, so we confirm it before anything is agreed. The work covers air-to-water heat pumps, air-to-air heat pumps and hot water cylinders, and people most often call us about finding a place for the outdoor unit and deciding which kind of heat pump suits the home.
In a London area like Long Ditton, many homes are flats or terraces with little outside space, which affects which heat pump suits. An air-to-water system needs space outside and usually a hot water cylinder inside, while an air-to-air system needs less space.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

Long Ditton: your questions answered
Can I have air conditioning in a flat in Long Ditton?
In many cases, yes, once the lease and the building’s rules are checked. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Can I get the Boiler Upgrade Scheme grant in Long Ditton?
Long Ditton is in England, where the Boiler Upgrade Scheme runs. The amount depends on the type of heat pump, and the survey confirms which applies. You don’t apply yourself: the MCS certified installer does, which is us.
How much time does a heat pump install need?
The work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. We confirm the timing after the survey, so phone us on 07833 053749 to arrange one.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Every visit is recorded and F-Gas records kept where they apply.
What warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some terms depend on regular servicing by a qualified engineer so it’s worth keeping the service records.
What accreditations do you have?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re members of Checkatrade too.
Do you provide F-Gas records?
Yes. It’s your proof of what was done: the date, the work, and any refrigerant added or recovered.
What a heat pump looks like in Long Ditton
The Valuation Office Agency’s council tax figures put about 35% of homes in Long Ditton and the neighbourhoods around it before 1919, and about 53% of households live in flats, according to the last census (2021). In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. Flats are often harder for air-to-water systems, so we look at whether air-to-air suits better. For a London home, the outdoor unit position and the MCS noise check need careful planning.
Older homes near Church of St Mary may need extra checks for planning and heat loss before a heat pump is designed. Hampton Court Palace, roughly 1.5 miles north-west, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.

How it works
Protection comes first: sheets over the floor and any furniture nearby, and we ask before moving anything. Then the electrics are made safe and the work begins. The work on site takes a few days for most air-to-water installations, with air-to-air systems often quicker, and we clear up before we go. A note on parking and access helps us plan a visit to Long Ditton.
- You tell us about the home and what you want from a heat pump.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- We recommend air-to-water or air-to-air and check the grant position.
- We install the heat pump and connect it up.
- After commissioning, you get the MCS certificate and a handover.
Getting ready for the visit
- Clear the space around the indoor unit, or where it will go
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Make sure someone can let us in at the agreed time
Getting a price
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.
Advice
For landlords and property managers
Records are where property maintenance often slips. Every visit is written up, with F-Gas records wherever refrigerant work is involved, so you can show what was done and when.
For anyone managing more than one building, we can quote and plan the work across all of them. Each property gets its own records, so the files stay tidy.

What happens if it’s left?
Replacing a boiler in a hurry when it breaks leaves little time to consider a heat pump. Surveying and designing in advance means the system is sized right and any grant is applied for before you need the heat. In London, hot spells can bring a rush of calls, so planning the work in Long Ditton before summer avoids the wait.
Putting several jobs into one visit often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.
