Air source heat pumps for homes and businesses in Sydenham
Heat pumps run at lower flow temperatures than most boilers which means some radiators may need upsizing. We check each radiator against the room’s heat loss, and the quote sets it out. If the problem is questions about listed buildings or conservation areas and questions about the Boiler Upgrade Scheme, we can help.
Homes around Sydenham typically have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

What a heat pump looks like in Sydenham
Roughly a third of a mile or less from central Sydenham, you reach the Sydenham Conservation Area. Listed buildings are part of the picture here: about 23 within half a mile of the centre, such as Church of St Mary (grade II*). Where a home is affected, the outdoor unit position is settled with the local planning authority (typically South Oxfordshire council) before the heat pump design is finished. About 75% of households live in detached or semi-detached houses, according to the 2021 Census. Houses usually have space for an outdoor unit and a hot water cylinder.
If your home is listed, like Adwell House about 2.4 miles south-west, listed building consent comes before any heat pump work. Period properties close to Church of St Mary can suit a heat pump, though insulation and any heritage protection are checked first.
Sydenham is about 3 miles south-east of Thame, in Oxfordshire. Across the OX39 area, our engineers can take on air source heat pumps. Our list for Oxfordshire has 443 entries and Sydenham is among them. Guildford, roughly 36 miles off, has its own page on this site.

What else we do in Sydenham
Managing agents and facilities teams in Sydenham
Facilities teams in offices, schools and public buildings book us too in Sydenham and across Oxfordshire. Larger buildings can be done in stages around the people who use them.
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We can quote either party, and the paperwork can go to both.
Sydenham questions
Is Sydenham within the area you cover?
Yes, smaller places are covered as well as towns. Send a few details and photos, and we reply the same working day.
Is the heat pump grant available in Sydenham?
Sydenham is in England, where the Boiler Upgrade Scheme runs. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. As an MCS certified installer, we apply for it on your behalf.
Do you offer emergency call-outs?
Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we will advise on what to do next.
How long does a heat pump installation take?
Expect it to take from a couple of days to around a week, depending on the system and how much of the heating changes. How much of the heating changes decides most of the time and the timing is set out with your quote.
Is a heat pump permitted development?
Often not in England, as many heat pumps on houses are permitted development, if the conditions are met. The outdoor unit must be 1.5 m³ or less, comply with MCS 020(a), not be cooling-only and not be within a listed building’s curtilage.
Which manufacturers do you install and repair?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Do you offer maintenance contracts?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is recorded, with F-Gas records where refrigerant work is involved.
How the job changes from property to property
The Boiler Upgrade Scheme
Not every home qualifies, so we check before you commit.
Air-to-air heat pumps
Air-to-air heat pumps warm rooms through indoor units and can cool them in summer. Hot water needs a separate source so you will need another way to heat it.
What you can do yourself, and what needs us
Owner care supports servicing; it doesn’t replace it. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
The process
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. 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. Visits to Sydenham are agreed with you in advance and planned so the job can be finished in one trip where possible.
- It starts with a conversation about the home, the existing heating and your plans.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- You get a fixed-price quote, with any grant you are eligible for and the VAT explained.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
How to prepare
- Mention any roof access, ladders or high-level work
- Have the make and model of any existing unit to hand
- Give us access to the outside wall, roof or yard where the outdoor unit sits

“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
