Air source heat pumps in Fenn Street, done properly
An air-to-water heat pump heats water to a lower temperature than a typical boiler, so radiators may need to be larger to give out the same heat. The survey shows which rooms are fine and which need changes and anything that needs changing is in the quote. If the problem is choosing between air-to-water and air-to-air and moving away from fossil-fuel heating, we can sort it out.
For a home around Fenn Street that’s off mains gas and heated by oil or LPG, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump.
Each manufacturer sets its own warranty period. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

Different systems, different jobs
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 what applies to you.
Heat loss surveys
The survey covers the building fabric and how air moves through it, and the size of each room.
Fenn Street: your questions answered
Will you come out to Fenn Street?
Yes. Fenn Street is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Does sea air affect air conditioning in Fenn Street?
It can, as Fenn Street is within about 2 miles of the sea, where salt in the air is hard on coils and fixings. The outdoor unit position, its fixings and regular servicing all help near the sea.
Can I fit air conditioning or a heat pump myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Is there a Boiler Upgrade Scheme grant for air-to-air?
Yes, but only where it becomes the home’s main heating. The £2,500 applies when it replaces the fossil-fuel heating, covers the full heating demand, is fitted by an MCS certified installer and serves a home. Fitted alongside a boiler, it won’t qualify.
Do you work on systems someone else installed?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Are my radiators big enough for a heat pump?
We find out during the survey. Rooms where the radiator is big enough stay as they are, and any that need upsizing are set out in the quote.
How does the warranty work?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition so it’s worth keeping the service records.
Heat pumps in Fenn Street: local notes
Fenn Street is within about 2 miles of the coast. Coastal sites are worth mentioning at the survey, as salt air affects the outdoor unit and its fixings. VOA council tax data show about 41% of homes in the Fenn Street area were built in 2000 or later, and the 2021 Census found about 69% of households in detached or semi-detached houses. Newer homes normally lose less heat, which tends to suit a heat pump well. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.
If your home is one of the older properties near Church of St Mary, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. Every heat pump design starts with a room-by-room heat loss calculation.

Pricing air source heat pumps in Fenn Street
Typical ranges are on our prices page, but every job is priced on its own. What we look at:
- The equipment or parts the job needs
- Whether we need access equipment for high-level work
- What kind of system it is
The pipe route, the height of the units and how we reach them all affect the cost. We take each of them into account, and the price is fixed before we start.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- Where the property is and what kind of building it is
- A short video of any fault, such as a noise or a flashing light
- A close-up of the unit’s label showing the model number

Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. The work itself takes a few days for most air-to-water installations, with air-to-air systems often quicker. A few photos help us make the most of a visit to Fenn Street.
