Air source heat pumps in Hornsey
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 hot water cylinders, air-to-water heat pumps and air-to-air heat pumps, and the jobs we see most are deciding which kind of heat pump suits the home and plans to switch to electric heating with a heat pump.
Terraced houses in a London area like Hornsey can suit a heat pump well, provided the outdoor unit can sit somewhere that passes the MCS noise check.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

System by system
Air-to-water heat pumps
Flow temperatures are lower than with a typical boiler, so radiator sizes matter.
Radiators and underfloor heating
Underfloor heating suits a heat pump’s lower flow temperature, and we can connect to it where it’s already in.
How it works
If the system has to be off for part of the visit, we tell you before work begins, so you can plan around it. For businesses, we can typically work room by room or zone by zone. On site, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Send us a few phone pictures and we can often price a straightforward job in Hornsey before visiting.

Heat pumps in Hornsey: local notes
The Valuation Office Agency’s council tax figures put about 63% of homes in the Hornsey area before 1919, and about 70% of households live in flats, according to the last census (2021). 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. Flats are often harder for air-to-water systems, so we look at whether air-to-air suits better. For a London home, the outdoor unit position and the MCS noise check need careful planning.
Bruce Castle, roughly 2 miles north-east, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.

What we are called out for in Hornsey
Extensions, renovations and loft conversions are a natural time to rethink the heating. It’s simpler to plan radiators, pipework and a cylinder while the builders are in.
Any of these is worth a proper look:
- Deciding which kind of heat pump suits the home
- Working out whether radiators need upsizing
- No space for a hot water cylinder
If your home is one of the older properties near Church of Holy Innocents, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

- If the quote is based on a survey, pictures or a diagnosis
- Whether they hold F-Gas company certification, not just individual qualifications
FAQs for Hornsey
Is the heat pump grant available in Hornsey?
Hornsey is in England, where the Boiler Upgrade Scheme runs. The amount depends on the type of heat pump, and the survey confirms which applies. You don’t apply yourself: the MCS certified installer does, which is us.
Do I need planning permission for a heat pump in Hornsey?
That depends on the building and where the outdoor unit goes. The centre of Hornsey is in the Hillfield Conservation Area. 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 Hornsey, normally Haringey council) first.
Do I need new radiators for a heat pump?
That depends on the room’s heat loss and the radiator’s size. We check them all during the survey and the quote shows what’s needed.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Tell us who should receive the paperwork.
Does servicing affect my warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Keep every service record either way.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is written up and F-Gas records kept where they apply.
