How the job changes from property to property
VAT on heat pumps
For air-to-air systems, HMRC’s view depends on the product and the situation and the VAT is confirmed on your quote.
Outdoor unit position and planning
Flats and blocks of flats have different limits, and Article 4 directions can remove rights. Listed building consent is a separate matter, and we check the position for your property.
Air source heat pumps in South Harefield, done properly
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home; adding it alongside a boiler doesn’t qualify. Typical jobs include checking eligibility for a heat pump grant and deciding on the outdoor unit position, across underfloor heating, homes heated by oil, LPG or gas and air-to-water heat pumps.
If your home in or near South Harefield is heated by oil, LPG or electric heaters with no mains gas, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027, on top of the £7,500.
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 anything chargeable is done.

Common questions in South Harefield
Is a heat pump in South Harefield permitted development?
It comes down to the building and the spot chosen for the outdoor unit. The Widewater Lock Conservation Area is close to the centre of South Harefield. 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 do not 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 Hillingdon council, which is typically the planning authority for South Harefield.
Can I get the Boiler Upgrade Scheme grant in South Harefield?
South Harefield 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. We hold MCS certification, so the application is ours to make for you.
Do you look at the job first?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
Why does F-Gas certification matter?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before booking, and we’re happy to show ours.
Will my radiators work with a heat pump?
Some radiators may be fine as they are, and some may need to be larger. At the lower temperatures a heat pump uses, radiators need more surface, and the survey checks each one.
How does the warranty work?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.
Do you protect the property while you work?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
Let and managed properties
Records are where property maintenance often slips. Each visit is written up, plus the F-Gas records where refrigerant is involved, ready for a tenant, a buyer or an inspection.
If you look after several properties, we can quote and plan the work across all of them. Each property gets its own records, so the files stay tidy.
Leave it or put it right?
Planning rules have specific conditions. We look at the planning position early, so there are no surprises, including conservation areas, listed buildings and Article 4 directions. Planning ahead for a job in South Harefield means we can bring everything needed.
Leaving a fault or an overdue service rarely makes the work cheaper. Small problems, from blocked filters to slow leaks, tend to get worse, and a system working harder than it should costs more to run. If you are unsure, call 07833 053749 or use the quote form for straight advice and a fixed price.
