Heat loss surveys
A heat loss survey measures how much heat each room loses on a cold day. It’s the basis for sizing the heat pump and the radiators.
Air-to-air heat pumps
Air-to-air heat pumps are now covered by permitted development rules in England, subject to conditions. Cooling-only units are not included and need a check with the council.
Air source heat pumps in Lissenden Gardens
A heat pump takes heat from the outside air and moves it into your home with electricity running the compressor and fans. It works on the same principle as air conditioning, run the other way and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. The work covers radiator systems, hot water cylinders and underfloor heating, and common reasons people get in touch are checking whether planning permission is needed and radiators that may be too small for a heat pump.
In a London area like Lissenden Gardens, 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 air-to-air units take less room.
We’re an F-Gas certified company, 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.

Questions from Lissenden Gardens
Is the heat pump grant available in Lissenden Gardens?
Yes, the scheme covers homes in England, including Lissenden Gardens, if they qualify. The amount depends on the type of heat pump, and the survey confirms which applies. The installer applies, and we’re MCS certified.
Can I have air conditioning in a flat in Lissenden Gardens?
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.
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 are members of Checkatrade too.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
When will I hear back?
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.
What’s the difference between air-to-water and air-to-air heat pumps?
The right choice depends on the property and what you need. The grant is £7,500 for eligible air-to-water systems and £2,500 for air-to-air in limited cases. We explain the options after the survey.
How long will it take to install a heat pump?
Expect it to take anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. The cylinder, the radiators and the pipework make the biggest difference, and we confirm the timing with your quote.

How it works
Think of the visit in three stages: diagnose, treat and sign off. First we check the system or the space against the plan, then we do the work, and finally we test, record and explain. Most of the time goes on the middle part, which takes from a couple of days to around a week, depending on the system and how much of the heating changes. For a job in Lissenden Gardens, tell us about parking, permits and access to the building when you get in touch.
- It starts with a conversation about the home, the existing heating and your plans.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Before we arrive
- Plan for pets to be kept clear during the visit
- Mention any managing agent or landlord rules we need to follow
- Have the make and model of any existing unit to hand

Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price so you know the cost before we begin.

Heat pumps in Lissenden Gardens: local notes
The Valuation Office Agency’s council tax figures put about 49% of homes across Lissenden Gardens and its surrounding area before 1919, and Census 2021 figures found about 79% of households live in flats. 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. For flats, the first questions are where an outdoor unit could go, whether a cylinder fits and what the lease allows. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Period properties close to Highgate Road Chapel can suit a heat pump, though insulation and any heritage protection are checked first. With Keats House about 0.8 miles west, it’s worth asking whether your own home is listed before planning a heat pump.
