About our air source heat pumps in Foster Street
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 the quote sets it out. The work covers radiator systems, air-to-air heat pumps and air-to-water heat pumps, and the jobs we see most are no space for a hot water cylinder and checking emitters for a heat pump.
If your home in or near Foster Street is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump, on top of the £7,500.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler, so keep it safe.

Common questions in Foster Street
Is a heat pump in Foster Street permitted development?
That depends on the building and where the outdoor unit goes. Historic England lists about 5 buildings and structures within half a mile of the centre of Foster Street. 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 Foster Street, typically Epping Forest council).
Can I get the Boiler Upgrade Scheme grant in Foster Street?
Yes, the scheme covers homes in England, including Foster Street, if they qualify. 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 you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and explain why.
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.
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 circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
What does an air-to-water heat pump cost?
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 £7,500 through the Boiler Upgrade Scheme, and we confirm eligibility before you commit.
How much time does a heat pump install need?
The work takes a few days for most air-to-water installations, with air-to-air systems often quicker. The survey lets us set a firm programme, so give us a ring on 07833 053749 or use the quote form to arrange one.
Looking after it afterwards
Every system needs looking after, and most of it is easy. Our tips:
- Keep the MCS certificate with the manufacturer’s paperwork
- Know the servicing conditions in your warranty
- Keep to regular servicing
In cold, damp weather the outdoor unit runs a defrost cycle from time to time. It may give off steam or sound different for a few minutes and it’s part of how the system works.
Keep radiators and indoor units unobstructed so the heat can get into the room.
Fixed-price quotes for air source heat pumps in Foster Street
We quote each job individually. These are the things that affect it:
- How far the pipework has to run, and where
- Access, including height, roofs and ladders
- The electrical supply and whether a new circuit is needed
Several rooms, units or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.
What to send for a quote
Simple jobs can often be priced from photos and some basics. Useful things to send:
- A few pictures of the room and the wall the unit is on, or will go on
- The outside wall, roof or yard where the outdoor unit sits or would go
- Any error code or flashing light on the display

What we do, step by step
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. 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 from a couple of days to around a week, depending on the system and how much of the heating changes. Seeing the property in photos first means the trip to Foster Street can be planned properly.
- First we find out about the property, the heating you have now and what you’re hoping for.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- Commissioning, MCS certification and a handover of the controls finish the job.
Before we arrive
- Unlock any gate, garage or side passage we need
- Mention any managing agent or landlord rules we need to follow
- Name a contact who can meet us at the agreed time

From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
