Questions from Cannon's Green
Is Cannon's Green within the area you cover?
Yes. Cannon's Green is within the area we cover across London and the South East. A few pictures and the postcode are enough to get things started.
Can I get the Boiler Upgrade Scheme grant in Cannon's Green?
Cannon's Green is covered, as the scheme runs across England and Wales. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. The installer applies, and we are MCS certified.
Do you protect the property while you work?
We start with protection: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
Do I get paperwork after the visit?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
Which manufacturers do you install and repair?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and tell you why.
What’s the price of a heat pump installation?
£8,000–£16,000 (0% VAT on homes) for air-to-water, before the grant. The final price depends on the heat loss survey, the radiators and the cylinder, and you get a fixed-price quote.
Do you work on systems someone else installed?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Air source heat pumps in Cannon's Green, done properly
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. 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, so an add-on next to a boiler is not eligible. Common call-outs are for comparing heat pump types and checking eligibility for a heat pump grant, across underfloor heating, air-to-air heat pumps and homes heated by oil, LPG or gas.
Older and listed homes in villages like Cannon's Green need extra care, and permitted development does not cover listed buildings, so consent comes first.
Warranty periods vary by brand and by product. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

How the visit works
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. For businesses, we can normally work room by room or zone by zone. On site, it 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. Seeing the property in pictures first means the trip to Cannon's Green can be planned properly.

Why deal with it now?
Replacing a boiler in a hurry when it breaks leaves little time to consider a heat pump. Surveying and designing in advance means the system is sized right and any grant is applied for before you need the heat. A system that is left with a fault, or without a service, usually costs more to run.
What you pay depends on the system and the number of rooms or units, the access and what the work involves. We give you a fixed price before work begins, so there are no surprises.

Owner checks or an engineer?
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo or a short video of the display is even better.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Common problems we fix in Cannon's Green
Some people want to move away from burning fossil fuels at home. With a heat pump, the heat comes from the air outside and the system runs on electricity and that is the appeal for many households.
Look out for any of the following:
- Plans to switch to electric heating with a heat pump
- Questions about listed buildings or conservation areas
- Questions about where the outdoor unit can go
Every heat pump design starts with a room-by-room heat loss calculation.
Questions to ask before booking
- How extra work would be agreed if they find something unexpected
- Whether the company is F-Gas certified, and whether you can check it
- Whether anyone has checked the property or the system first
Air source heat pumps in Cannon's Green: the local picture
The 2021 Census found about 87% of households in detached or semi-detached houses. Houses typically have space for an outdoor unit and a hot water cylinder. On the National Heritage List, around 19 entries fall within 0.5 miles of the middle of Cannon's Green; Fyfield Hall (grade I) is one. That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where necessary, we check with the local planning authority (typically Epping Forest council).
Older homes near Church of St Nicholas may need extra checks for planning and heat loss before a heat pump is designed.
