How we handle air source heat pumps in Offham
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. In England and Wales, the Boiler Upgrade Scheme offers a £7,500 grant towards an eligible air-to-water installation, and as the installer we apply for it on your behalf. Not every home qualifies, so we check eligibility before you commit. Common call-outs are for wanting to stop using oil, LPG or gas for heating and not knowing whether a grant applies, across air-to-air heat pumps, radiator systems and air-to-water heat pumps.
Older and listed homes in villages like Offham need extra care, and permitted development does not cover listed buildings, so consent comes first.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

Air source heat pumps in Offham: the local picture
About 37% of households live in terraced houses, according to Census 2021 figures. Terraced houses share walls with neighbours, which helps, but the outdoor unit position needs care with noise next door. Offham’s centre falls inside the Hamsey (Offham) Conservation Area. Historic England lists about 12 buildings and structures within half a mile of the centre of Offham, including Offham House (grade II*). Where a home is affected, the outdoor unit position is settled with the local planning authority (typically Lewes council) before the heat pump design is finished.
Historic houses such as Anne of Cleves House, about 1.7 miles south-east, are a reminder that listed homes need consent before a heat pump goes in.
Offham is about 1 mile north-west of Lewes, in East Sussex. From the centre of Offham to the outskirts, we cover air source heat pumps, from small jobs to large ones. Our East Sussex coverage runs to 289 places, and Offham is one of them. The nearest of our city pages is Brighton, around 7 miles from Offham.
The closest recent job we can point to from Offham was on High Street, Lewes (BN7), about 1 mile south-east: installing a Fujitsu wall-mounted split system in the retail area, with the outdoor unit positioned in the rear courtyard to preserve the listed street frontage.
Our working area takes in BN7 in full. If you are just outside Offham, we cover Hamsey (1 mile north-east), Lewes (1 mile south-east), South Malling (1 mile south-east), Southover (2 miles south-east) and Cliffe (2 miles south-east).

What happens on the day
Our engineers arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. On site, it 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 pictures first means the trip to Offham can be planned properly.
- We start with your plans and the property.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- We install the heat pump and connect it up.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Before we arrive
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Plan for pets to be kept clear during the visit
- Arrange for someone to be there to let us in
How to get a quote
Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. After a look at the job, by pictures or a survey, the price is fixed. To get going, ring 07833 053749 or drop us a line.

Offham: your questions answered
Does the Boiler Upgrade Scheme cover homes in Offham?
Yes, the scheme covers homes in England, including Offham, if they qualify. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. The installer applies, and we are MCS certified.
Will you come out to Offham?
We do. Villages and hamlets get the same service as the bigger towns. A few photos and the postcode are enough to get things started.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
Do you offer emergency call-outs?
Yes, day and night. Call the emergency line and tell us the make, the symptoms and any error code, and we will advise on what to do next.
Why does F-Gas certification matter?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before you book anyone, and we’re happy to show ours.
Does servicing affect my warranty?
It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Keep every service record either way.

When to call us in Offham
An ageing boiler is often the moment people start thinking about a heat pump. Starting early leaves time for the survey, the design and any grant application, rather than rushing a replacement in winter.
Any of these is worth a proper look:
- Checking emitters for a heat pump
- Moving away from fossil-fuel heating
- Questions about listed buildings or conservation areas
If your home is near Cooksbridge station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits.
