Air source heat pumps in Sullington, done properly
Air source heat pumps collect heat from outdoor air and bring it inside with electricity running the compressor and fans. It works on the same principle as air conditioning, run the other way, and air-to-air heat pumps are sometimes simply called air conditioning. The work covers hot water cylinders, air-to-air heat pumps and underfloor heating, and the jobs we see most are wanting to stop using oil, LPG or gas for heating and an oil, LPG or gas boiler near the end of its life.
Older and listed homes in villages like Sullington need extra care, and permitted development does not cover listed buildings, so we check consent first.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Air source heat pumps in Sullington: the local picture
The 2021 Census found about 84% of households in detached or semi-detached houses. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
With Parham House about 2.5 miles west, it’s worth asking whether your own home is listed before planning a heat pump. Period properties close to The Parish Church of St Mary can suit a heat pump, though insulation and any heritage protection are checked first.

What else we do in Sullington
How the job changes from property to property
Hot water cylinders
Cylinder size is based on your household’s needs.
Air-to-water heat pumps
An air-to-water heat pump heats water for your radiators or underfloor heating and your hot water cylinder. It takes over from the boiler and we install it to MCS standards.
Rented and managed buildings
Keeping records across a portfolio is half the battle. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, so you can show what was done and when.
When the building owner and the occupier are different, the lease or tenancy agreement normally sets out who maintains what. We can quote either party and send the records to whoever needs them.
What you can do yourself, and what needs us
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
Don’t move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. Ask us to quote for a move instead.
Common questions in Sullington
Can I fit a heat pump in Sullington without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. There’s a conservation area, the Sullington Conservation Area, close to central Sullington. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask Horsham council, which is typically the planning authority for Sullington.
Can I get the Boiler Upgrade Scheme grant in Sullington?
Sullington is in England, where the Boiler Upgrade Scheme runs. 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. As an MCS certified installer, we apply for it on your behalf.
Do you have a 24/7 line?
Yes. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we will agree what happens next.
Which manufacturers do you install and repair?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Do I get paperwork after the visit?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
Is there a survey before the work?
Yes. For simple jobs, pictures and a few details can be enough, while larger systems and faults that need testing are seen on site.
How quickly will you reply?
On the same working day you contact us. Then we agree a date that works for you, with a fixed price before work starts.
How the visit works
The work area is kept tidy throughout, with sheets down and mess cleared as we go. Any holes, fixings or cable routes are agreed with you before we drill. On site, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Somewhere like Sullington, it helps to know about lanes, gates and where to park.
