About our air source heat pumps in Islington
Air source heat pumps collect heat from outdoor air and bring it inside, using electricity to drive the process. 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 underfloor heating, hot water cylinders and radiator systems, and the jobs we see most are plans to switch to electric heating with a heat pump and planning and permitted development questions.
In a London area like Islington, many homes are flats or terraces with little outside space, and that decides which kind of heat pump works. An air-to-water system needs space outside and usually a hot water cylinder inside, while an air-to-air system needs less space.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

What we do, step by step
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. On site, the work takes a few days for most air-to-water installations, with air-to-air systems often quicker. The more we can see beforehand, the smoother the visit to Islington will be.

Heat pumps in Islington: local notes
VOA council tax data put about 49% of homes in the Islington area before 1919, and about 80% of households live in flats, according to the 2021 Census. Period properties can still suit a heat pump, but the design has to start from accurate heat loss figures. In flats, space for an outdoor unit and a cylinder can be limited, and the lease and freeholder come into it, so air-to-air is sometimes the better fit. In London, outside space and the rules for flats often decide which kind of heat pump suits.
Dr Johnson's House, roughly 1.6 miles south, is a reminder to check your home’s listing status: permitted development does not cover listed buildings.

Do you need air source heat pumps in Islington?
An ageing boiler is often the moment people start thinking about a heat pump. Planning the change before the boiler fails gives you time to survey, design and apply for any grant, rather than rushing a replacement in winter.
It’s time to call us if you are dealing with:
- Choosing between air-to-water and air-to-air
- Working out whether radiators need upsizing
- Questions about where the outdoor unit can go
Period properties close to St Mary's Church can suit a heat pump, though insulation and any heritage protection are checked first.
Questions to ask before you book
- Proof of F-Gas company certification
- What paperwork you’ll receive afterwards
- Whether the manufacturer’s warranty depends on regular servicing
What happens if it’s left?
A heat pump sized without a proper heat loss survey can struggle in cold weather or run inefficiently. Doing the survey properly from the start avoids that. Approvals for flats in Islington can take longer than the install itself.
The cost depends on the type of system and how many units are involved, how easy the units are to reach and the parts and time the job needs. We give you a fixed price before we start, so you know where you stand.
Why people in Islington choose us
- MCS certified for heat pumps
- Electrical work covered by our NICEIC approval

Common questions in Islington
Can I fit a heat pump in Islington without planning permission?
It depends on the property. The centre of Islington is in a conservation area. 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 Islington, normally Islington council).
Is the heat pump grant available in Islington?
Yes, the scheme covers homes in England, including Islington, if they qualify. The amount depends on the type of heat pump, and the survey confirms which applies. As an MCS certified installer, we apply for it on your behalf.
Will I get records for the system?
Yes. Each visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. Keep them with the manual and the warranty documents.
Do you work on commercial properties?
Yes. From one rented home to commercial buildings, the approach is the same: a look first, a fixed-price quote and written records.
Is there a survey before the work?
Yes. Every job is looked at first, either on a site survey or from photos and details for simple jobs. Then you get a fixed-price quote.
Is the equipment covered by a warranty?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition so it’s worth keeping the service records.
Does servicing affect my warranty?
For some brands, yes. Read the manufacturer’s terms, or send us the make and model and we’ll explain them and stick to the interval they set.
Before you call an engineer
Owner care supports servicing; it doesn’t replace it. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. If you need something moved, we can quote for it.
A customer’s words
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
