Air source heat pumps in Sudbury Hill
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. If you’re dealing with questions about where the outdoor unit can go and an oil, LPG or gas boiler near the end of its life, we can sort it out.
Homes in Sudbury Hill are often flats and terraces, where outside space is limited, which affects which heat pump suits. An air-to-water system needs space outside and normally a hot water cylinder inside, while an air-to-air system needs less space.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

Homes in Sudbury Hill and heat pumps
About 53% of homes in the Sudbury Hill area were built between the wars, according to Valuation Office Agency council tax records. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Period properties close to Church of St Andrew can suit a heat pump, though insulation and any heritage protection are checked first.

Questions from Sudbury Hill
Do I need permission to put air conditioning in my flat in Sudbury Hill?
Often, yes, but the lease and the freeholder typically have a say. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Is the heat pump grant available in Sudbury Hill?
Yes, the scheme covers homes in England, including Sudbury Hill, if they qualify. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. We hold MCS certification, so the application is ours to make for you.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Can you look at a system you didn’t fit?
Yes. Systems fitted by other companies are fine, on all the main brands. Send us the make and model, and any records you have.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before you book and we’ll gladly show you ours.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
How soon will you get back to me?
You’ll hear from us the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.

Looking after your system
So the system stays in good health:
- Diary the next service
- Ask about the grant before you commit
- File the MCS certificate safely
The warranty on the heat pump is the manufacturer’s, on its own terms. We go through the conditions with you, including any servicing they ask for.
Keep insulation and draught-proofing in good order because it reduces the heat the system needs to supply.
What we do, step by step
Each visit follows the same order: agree the plan on site, protect the area, do the work, check the system and explain it all to you. On site, 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. The more we can see beforehand, the smoother the visit to Sudbury Hill will be.

- A heat loss survey is carried out, room by room.

How to prepare

Common problems we fix in Sudbury Hill
A common reason is wanting to stop burning gas, oil or LPG. A heat pump runs on electricity and takes heat from the outside air and that’s the appeal for many households.
What we are most often called about:
- Questions about the Boiler Upgrade Scheme
- Working out whether radiators need upsizing
- Choosing between air-to-water and air-to-air
If you live near Sudbury & Harrow Road station, the survey compares air-to-water and air-to-air for your home before anything is quoted.
What your quote should include
- If the quote is based on a survey, photos or a diagnosis
- Whether they hold F-Gas company certification, not just individual qualifications
- Who does the electrical work, and whether they can certify it
System by system
Hot water cylinders
An air-to-water heat pump heats hot water through a cylinder. The survey looks at where it can go, especially if you have a combi boiler.
Radiators and underfloor heating
Heat pumps run at lower flow temperatures, so radiators may need to be larger, and the survey checks each one.
A customer’s words
“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.”
