When to call us in Leytonstone
The Boiler Upgrade Scheme has made people ask whether their home could qualify. Whether you can get the grant depends on your home and the scheme conditions, so we check before you commit.
Common reasons people call us are:
- Choosing between air-to-water and air-to-air
- Checking whether planning permission is needed
- No space for a hot water cylinder
Live in one of the older houses around Church of St John the Baptist? Expect the survey to look closely at heat loss and at the building’s planning status.
What your quote should include
- Whether the price is fixed or an estimate
- Who does the electrical work, and whether they can certify it
- Whether extra work needs your approval first
Air source heat pumps in Leytonstone
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. With air-to-air, hot water has to come from something else. We’re often asked to deal with an oil, LPG or gas boiler near the end of its life and checking whether planning permission is needed, across air-to-water heat pumps, radiator systems and hot water cylinders.
A terrace in Leytonstone shares walls with its neighbours, which helps keep heat in, as long as there’s a sensible spot for the outdoor unit and its noise is checked against the MCS planning standard.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Air-to-air heat pumps
Since 2025, air-to-air heat pumps can also be permitted development in England, subject to the conditions. Cooling-only units are not included and need a check with the council.
The Boiler Upgrade Scheme
Only one grant is available per property, and it can’t replace a low-carbon system. Hybrids are excluded.
Air source heat pumps around Leytonstone
About 65% of homes in the Leytonstone area were built before 1919, according to the Valuation Office Agency’s council tax figures, and the last census (2021) found about 50% 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. A flat may have no room for a hot water cylinder, and the freeholder typically has a say on the outdoor unit, which can tip the choice towards air-to-air. In London, outside space and the rules for flats often decide which kind of heat pump suits.
With Valentines Mansion about 2.4 miles east, it’s worth asking whether your own home is listed before planning a heat pump.

The process
Every visit follows the same order: agree the plan on site, protect the area, carry out the job, check the system and talk you through it. On site, the work takes from a couple of days to around a week, depending on the system and how much of the heating changes. Before a visit in Leytonstone, we ask where the van can stop and how we reach the outdoor unit.
- First we talk through the property and the current system.
- A heat loss survey is carried out, room by room.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- You get a fixed price, with any grant and the VAT set out.
- We install, commission and register the system under MCS.
Before we arrive
- Mention any parking restrictions near the property
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Find the manual or the paperwork for the system, if you have it

Your questions about air source heat pumps in Leytonstone
Can I fit a heat pump in Leytonstone without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. Historic England lists about 7 buildings and structures within half a mile of the centre of Leytonstone. 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 local planning authority (for Leytonstone, typically Waltham Forest council).
Do I need permission to put air conditioning in my flat in Leytonstone?
Often, yes, but the lease and the freeholder normally have a say. 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.
What does an air-to-water heat pump cost?
Expect £8,000–£16,000 for an air-to-water system, with 0% VAT on homes, before the grant is taken off. The heat pump size, radiator changes and the cylinder decide where in that range you are, and air-to-air systems are priced after a survey.
Will my radiators work with a heat pump?
It depends on each radiator and the room it heats. Heat pumps run at lower flow temperatures, so radiators give out less heat so we check every radiator against the room’s heat loss.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for breakdowns that can’t wait. Ring 07833 053749 any time and explain the problem.
Do you work on all makes?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
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. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions. We explain the options after the survey.
What you can do yourself, and what needs us
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. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
What a customer said
“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.”
