Air source heat pumps for homes and businesses in Fish Island
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. Guesswork leads to systems that are too big or too small. The work covers homes heated by oil, LPG or gas, underfloor heating and air-to-air heat pumps, and the jobs we see most are replacing a combi boiler with a heat pump and checking emitters for a heat pump.
A terrace in Fish Island shares walls with its neighbours, which helps keep heat in, provided the outdoor unit can sit somewhere that passes the MCS noise check.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We will tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

What we do, step by step
You don’t need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and the rest is down to us. At the end, we tidy up and run through the work with you. Parking bays, permits and roof or balcony access are the first things we ask about in Fish Island.
- It begins with your house and the heating it relies on now.
- Every room’s heat loss is worked out on site.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- You get a fixed price, with any grant and the VAT set out.
- Installation, commissioning and MCS registration complete the job.
Preparing for the visit
- Clear access to the fuse board
- Let us know if the building has a permit or sign-in process
- Make sure we can reach the outdoor unit, or where it will go

Leave it or put it right?
Planning rules have specific conditions. Checking the position for your home at the survey stage avoids surprises later covering listed buildings, conservation areas and any Article 4 direction. Planning ahead in Fish Island means you choose the date, not the weather.
Putting the work off seldom saves money. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you’re unsure, phone 07833 053749 or fill in the contact form and we will give you an honest view and a fixed price.

What the work involves, system by system
Air-to-water heat pumps
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. Eligible homes in England and Wales can get a £7,500 Boiler Upgrade Scheme grant towards it and the installer applies.
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.
Common questions in Fish Island
Is a heat pump in Fish Island permitted development?
The answer turns on the property and where the outdoor unit would sit. The Fish Island Conservation Area is close to the centre of Fish Island. 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 Fish Island, typically Tower Hamlets council) first.
Can I get the Boiler Upgrade Scheme grant in Fish Island?
Yes, if the home and the heat pump meet the scheme’s rules: Fish Island 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 I need to service the system to keep the warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim and we’ll tell you what your brand asks for.
Should I choose air-to-water or air-to-air?
The right choice depends on the property and what you need. The grant is £7,500 for eligible air-to-water systems and £2,500 for air-to-air in limited cases. We explain the options after the survey.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Which manufacturers do you install and repair?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and tell you why.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
When to call us in Fish Island
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.
If any of these sounds familiar, it’s worth a diagnosis:
- Checking emitters for a heat pump
- No space for a hot water cylinder
- Moving away from fossil-fuel heating
If your home is listed, like Sutton House about 1.3 miles north-west, listed building consent comes before any heat pump work.

Homes in Fish Island and heat pumps
The Valuation Office Agency’s council tax figures show about 49% of homes in Fish Island and the neighbourhoods around it were built in 2000 or later, and the 2021 Census found about 81% of households live in flats. Lower heat loss in recent homes often means a smaller heat pump and fewer radiator changes. For flats, the first questions are where an outdoor unit could go, whether a cylinder fits and what the lease allows. In London, outside space and the rules for flats often decide which kind of heat pump suits.
Live in one of the older houses around St Mary of Eton? Expect the survey to look closely at heat loss and at the building’s planning status.
