Angel air source heat pumps
Our engineers work in Angel on heat pump installation. Diagnosis first, a fixed price and proper paperwork when we finish.
- Replacing a combi boiler with a heat pump
- Deciding which kind of heat pump suits the home
- Radiators that may be too small for a heat pump
What happens on the day
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. In a business, work can often be done one area at a time. The work takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. Photos of the room and where the outdoor unit could go let us plan most of a visit to Angel in advance.
- First we talk through the property and the current system.
- A heat loss survey is carried out, room by room.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- Cost, grant and VAT appear on one fixed-price quote.
- We install, commission and register the system under MCS.
Getting ready for the visit
- Tell us about any building rules, permits or sign-in
- Have the make and model of any existing unit to hand
- Let us know if the units are on a roof, a high wall or in a locked area
How to get a quote

Air source heat pumps for homes and businesses in Angel
A £2,500 grant is available for some air-to-air heat pumps, with conditions. The system must replace the existing fossil-fuel heating and meet the home’s full heating demand, it must be installed by an MCS certified installer, and it must be in a home; adding it alongside a boiler doesn’t qualify. The work covers radiator systems, underfloor heating and air-to-water heat pumps, and people most often call us about checking emitters for a heat pump and wanting to stop using oil, LPG or gas for heating.
Homes in Angel are often flats and terraces, where outside space is limited, 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 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. Our engineers hold the F-gas qualifications needed to work on refrigerant.

What else we do in Angel
Air source heat pumps around Angel
VOA council tax data put about 39% of homes in Angel and the neighbourhoods around it before 1919, and the last census (2021) found about 88% 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 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.
If your home is one of the older properties near St Mark's Church, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
Angel is about 1 mile north-east of St Pancras, in Greater London. Across the N1 area, we can help with air source heat pumps. In Greater London alone we list 764 places and Angel is among them.
Our nearest recent job to Angel was on Greenwich High Road, Greenwich (SE10), about 6 miles south-east: installing a Mitsubishi Electric wall-mounted unit in the retail area and a second unit in the stockroom and office.

How the job changes from property to property
Hot water cylinders
Cylinder size is based on your household’s needs.
Heat loss surveys
The survey works out the heat needed room by room. It’s the basis for sizing the heat pump and the radiators.
When to call us in Angel
A common reason is wanting to stop burning gas, oil or LPG. With a heat pump, the heat comes from the air outside and the system runs on electricity, which is why it fits that aim.
If any of these sounds familiar, it’s worth a diagnosis:
- Finding a place for the outdoor unit
- Working out where a cylinder could go
- Radiators that may be too small for a heat pump
Dr Johnson's House lies about 1.2 miles south. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.
What to look for in a quote
- What paperwork you’ll receive afterwards
- Whether anyone has checked the property or the system first
- Whether extra work needs your approval first
Angel questions
Do I need permission to put air conditioning in my flat in Angel?
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.
Can I fit a heat pump in Angel without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. Central Angel sits inside a 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 Angel, typically Islington council) first.
Do you look at the job first?
Yes, always. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
When will I hear back?
We reply to enquiries the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Will skipping a service affect the warranty?
That depends on the brand. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim, so we explain the terms on your quote.
Will I get records for the system?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for problems that cannot wait for a planned visit. Ring 07833 053749 any time and explain the problem.
