Looking after your system
Here’s the after-treatment advice, short and simple:
- Know the servicing conditions in your warranty
- Ask about the grant before you commit
- Book a yearly service
We show you how to use the controls and explain how a heat pump works differently from a boiler. Heat pumps tend to work best running steadily rather than in short bursts so we set the controls up with you.
Leave space around the outdoor unit. It needs good airflow to collect heat from outside so keep it unobstructed.
How we handle air source heat pumps in Upper Walthamstow
We begin with a room-by-room heat loss survey. That tells us how much heat the home needs, room by room so the system is sized to match. Sizing by rule of thumb is not good enough. If the problem is working out whether radiators need upsizing and not knowing whether a grant applies, we can help.
Terraced houses in a London area like Upper Walthamstow can suit a heat pump well, provided the outdoor unit can sit somewhere that passes the MCS noise check.
We are an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Air source heat pumps in Upper Walthamstow: the local picture
About 40% of homes in Upper Walthamstow and the neighbourhoods around it were built before 1919, according to the Valuation Office Agency’s council tax figures, and the last census (2021) found about 51% 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. A flat may have no room for a hot water cylinder, and the freeholder normally 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 2.9 miles east, it’s worth asking whether your own home is listed before planning a heat pump. If you live near Wood Street station, the survey compares air-to-water and air-to-air for your home before anything is quoted.

What the work involves, system by system
Outdoor unit position and planning
Flats have tighter limits, and an Article 4 direction can remove permitted development rights. Listed building consent is a separate matter, and we check the position for your property.
Heat loss surveys
We look at walls, windows, floors, roofs and ventilation along with the room sizes.
What happens if it’s left?
Radiators that are too small for a heat pump’s lower flow temperature leave rooms cool. The survey picks this up before installation. Hot weather is when everyone in London wants air conditioning, so it’s easier to plan the work in Upper Walthamstow early.
Height, access and the distance between the indoor and outdoor units can all change the price. We take each of them into account and give you a fixed price before we start.

What we do, step by step
Testing is the last part of the visit wherever the system can be switched on. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. The visit takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Before a visit in Upper Walthamstow, we ask where the van can stop and how we reach the outdoor unit.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Before we arrive
- Dig out any previous service or F-Gas records
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Clear access to the fuse board

Your questions about air source heat pumps in Upper Walthamstow
Can I fit a heat pump in Upper Walthamstow without planning permission?
It depends on the property. The half-mile around the middle of Upper Walthamstow holds about 12 listed buildings and structures. 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 Waltham Forest council, which is normally the planning authority for Upper Walthamstow first.
Is the heat pump grant available in Upper Walthamstow?
Yes, if the home and the heat pump meet the scheme’s rules: Upper Walthamstow is in England, where it applies. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. We hold MCS certification, so the application is ours to make for you.
Do you look at the job first?
Yes. We always look before we price, either on a site survey or from photos and details for simple jobs. Then you get a fixed-price quote.
Which brands do you work with?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.
Do you cover Upper Walthamstow?
Yes. Upper Walthamstow is part of the area we cover, within the South East and London area we cover. We’re based in East Grinstead, West Sussex.
When will I hear back?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
How long will it take to install a heat pump?
A typical installation takes from a couple of days to around a week, depending on the system and how much of the heating changes. We plan the work so you’re without heating for as little time as possible, and we explain it in advance.
