About our air source heat pumps in Gunnersbury
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. In England and Wales, the Boiler Upgrade Scheme offers a £7,500 grant towards an eligible air-to-water installation and the installer makes the application. Eligibility depends on the property, so we confirm it before anything is agreed. Common call-outs are for finding a place for the outdoor unit and checking whether planning permission is needed, on air-to-water heat pumps, underfloor heating and air-to-air heat pumps.
In a London area like Gunnersbury, 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 typically a hot water cylinder inside, while an air-to-air system needs less space.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

What owners can safely do
Don’t move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. If you need something moved, we can quote for it.
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.

Questions from Gunnersbury
Can I have air conditioning in a flat in Gunnersbury?
In many cases, yes, once the lease and the building’s rules are checked. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Can I fit a heat pump in Gunnersbury without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. Central Gunnersbury is a short walk from the Thorney Hedge Conservation Area. 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 planning department at Hounslow council, normally the authority for Gunnersbury.
What VAT do I pay on a heat pump?
Homes pay 0% VAT on a heat pump installation until 31 March 2027, then 5%. Hotels and businesses pay the standard rate. Please treat this as general information, not tax advice.
How quickly will you reply?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
How much time does a heat pump install need?
An installation takes a few days for most air-to-water installations, with air-to-air systems often quicker. We confirm the timing after the survey, so ring us on 07833 053749 or write to us at info@aircondoctor.co.uk to arrange one.
Should I choose air-to-water or air-to-air?
Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms, and we help you choose. We install both types.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
Leave it or put it right?
Permitted development rules can change, and conditions vary between properties. We look at the planning position early, so there are no surprises, including conservation areas, listed buildings and Article 4 directions. Consents in London blocks can take time, which is another reason to plan the job in Gunnersbury early.
The price reflects the work, not guesswork. That is why every job is looked at first, and why the quote is fixed before we start.

What a heat pump looks like in Gunnersbury
About 37% of homes in and around Gunnersbury were built before 1919, according to VOA council tax data, and Census 2021 figures found about 66% of households live in flats. 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. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
If you live near Gunnersbury station, the survey compares air-to-water and air-to-air for your home before anything is quoted. Period properties close to St Michael's Church can suit a heat pump, though insulation and any heritage protection are checked first.

It takes several days for an air-to-water system with a new cylinder, less for an air-to-air system, and we clear up before we go.
