For landlords and property managers
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Tell us who the contact on site is and who should receive the paperwork, and we’ll keep everyone informed.
For anyone managing more than one building, we can plan visits across the portfolio and price them together. Every address has its own paperwork, so each one has its own history.
Air source heat pumps in Wiston, done properly
Many air source heat pumps can be installed as permitted development in England, without a planning application. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit can’t be used solely for cooling or sit within the curtilage of a listed building. We check the rules for your property as part of the survey. Typical jobs include questions about where the outdoor unit can go and checking emitters for a heat pump, on radiator systems, homes heated by oil, LPG or gas and air-to-water heat pumps.
If your home in or near Wiston 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.
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, as a manufacturer or a future engineer may ask to see them.

What the work involves, system by system
Air-to-air heat pumps
Since 2025, air-to-air heat pumps can also be permitted development in England, subject to the conditions. A unit used solely for cooling is not covered, so check with the council.
Hot water cylinders
The cylinder size depends on how much hot water the household uses.
Wiston: your questions answered
Is Wiston within the area you cover?
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.
Does the Boiler Upgrade Scheme cover homes in Wiston?
Yes, the scheme covers homes in England, including Wiston, if they qualify. 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. The installer applies, and we’re MCS certified.
Do you provide F-Gas records?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
What does an air-to-water heat pump cost?
For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air systems are priced after a survey, with the VAT confirmed on your quote.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Let us know who the records should go to.
Can you set up regular servicing?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is recorded and F-Gas records kept where they apply.
How long does a heat pump installation take?
Expect it to take a few days for most air-to-water installations, with air-to-air systems often quicker. The cylinder, the radiators and the pipework make the biggest difference, and we confirm the timing with your quote.
Owner checks or an engineer?
There are a few things you can safely do yourself: 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.
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and call us on 07833 053749, or email if that’s easier.
Air source heat pumps around Wiston
Buncton Chapel of All Saints, listed at grade I, is one of roughly 12 protected buildings and structures in the half-mile around Wiston’s centre. That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where necessary, we check with the planning team at Horsham council, which usually handles Wiston. 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.
Live in one of the older houses around All Saints Church? Expect the survey to look closely at heat loss and at the building’s planning status. A heat loss calculation decides the size of heat pump your home needs.

The middle part takes longest, which takes a few days for most air-to-water installations, with air-to-air systems often quicker.
