Before you call an engineer
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Owner care supports servicing; it does not replace it. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
Air source heat pumps in Monken Hadley, done properly
Every installation starts with a heat loss survey. It shows how much heat each room needs on a cold day, so the heat pump and the radiators or indoor units can be sized properly. Guesswork leads to systems that are too big or too small. We’re often asked to deal with questions about the Boiler Upgrade Scheme and working out whether radiators need upsizing, across homes heated by oil, LPG or gas, radiator systems and air-to-air heat pumps.
A terrace in Monken Hadley shares walls with its neighbours, which helps keep heat in, provided the outdoor unit can sit somewhere that passes the MCS noise check.
The records are your system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

Air source heat pumps in Monken Hadley: the local picture
About 42% of homes in Monken Hadley and the neighbourhoods around it were built before 1919, according to VOA council tax data. 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. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
If your home is listed, like Wyllyotts Manor about 2.4 miles north, listed building consent comes before any heat pump work.

Questions from Monken Hadley
Do I need planning permission for a heat pump in Monken Hadley?
That depends on the building and where the outdoor unit goes. The Monken Hadley Conservation Area takes in the middle of Monken Hadley. 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 the local planning authority (for Monken Hadley, typically Barnet council) first.
Do I need permission to put air conditioning in my flat in Monken Hadley?
Typically, yes, though leaseholders normally need the freeholder’s agreement. 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.
Which manufacturers do you install and repair?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We will work out which band applies to yours.
Do you work in Monken Hadley?
Yes. We cover Monken Hadley and the rest of Greater London, within the London and South East area we cover. To book, phone 07833 053749 or email us.
What’s the difference between air-to-water and air-to-air heat pumps?
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.
Are you F-Gas certified?
As the law requires for refrigerant work, we’re an F-Gas certified company. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
What we do, step by step
There’s very little for you to do on the day. Just let us in and point us to the units, or to where they’ll be fitted, and we take it from there. Before we leave, the area is tidied and we explain what we’ve done. Before a visit in Monken Hadley, we ask where the van can stop and how we reach the outdoor unit.
- We find out about your home and the heating you have now.
- A heat loss survey is carried out, room by room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- A fixed-price quote explains the cost, the grant position and the VAT.
- We install, commission and register the system under MCS.
How to prepare
- Dig out any previous service or F-Gas records
- Let us know if the building has a permit or sign-in process
- Keep pets and children away from the work area
Ask for a quote
Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. After a look at the job, by pictures or a survey, the price is fixed. To start, call us on 07833 053749 or fill in the contact form.

Looking after it afterwards
How well a system lasts depends on use and care. Here’s what we suggest:
- Keep the outdoor unit clear all year
- Keep up with insulation and draught-proofing
- Check eligibility for the Boiler Upgrade Scheme early
After commissioning, the installation is registered under MCS and you receive the certificate. Keep it with the manufacturer’s paperwork, as you may need it later.
Let the heat pump run steadily rather than switching it on and off, using the settings agreed at handover.
What we are called out for in Monken Hadley
Many enquiries start with a question about the Boiler Upgrade Scheme. Whether you can get the grant depends on your home and the scheme conditions and we confirm it before you go ahead.
If any of these sounds familiar, it’s worth a diagnosis:
- Questions about listed buildings or conservation areas
- Choosing between air-to-water and air-to-air
- Finding a place for the outdoor unit
If your home is one of the older properties near Parish Church of St Mary the Virgin, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
Questions to ask before booking
- Why the equipment they’re quoting suits the job
- What happens if the job turns out to be different on the day
- Whether the company is F-Gas certified, and whether you can check it
