Air source heat pumps in Duncton
Until 31 March 2027, a heat pump installed in residential accommodation carries 0% VAT, with 5% from 1 April 2027. This is HMRC’s energy-saving materials relief, which applies to homes rather than businesses. For air-to-air systems, we confirm the VAT on your quote. This is general information, not tax advice. If the problem is checking eligibility for a heat pump grant and plans to switch to electric heating with a heat pump, we can help.
If your home in or near Duncton is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump.
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 every service is written up.

Pricing air source heat pumps in Duncton
You’ll get a fixed price before we start. It takes into account:
- What state the existing equipment is in
- Whether it’s a simple split or a larger system
- Which make and model is being fitted or worked on
Putting the work off seldom saves money. 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, ring 07833 053749 or email us for straight advice and a fixed price.
Asking for a quote
There’s no need for technical detail. Just send:
- The outside wall, roof or yard where the outdoor unit sits or would go
- The remote or wall controller showing any error
- Your consumer unit or fuse board
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and many jobs can be priced from that.
How it works
The first job on site is protection: sheets over the floor and any furniture nearby, and we ask before moving anything. After that, anything electrical is made safe and we start. It 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, and we tidy up before we leave. For a place like Duncton, the timing is set with you and the travel is our side of the planning.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- 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.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Getting ready for the visit
- Find the manual or the paperwork for the system, if you have it
- Make sure we can reach the consumer unit or fuse board
- Let us know where we can park and unload
Getting a quote
Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.

Air source heat pumps around Duncton
VOA council tax data put about 43% of homes in and around Duncton before 1919, and Census 2021 figures found about 73% of households in detached or semi-detached houses. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Older homes near Church of Holy Trinity may need extra checks for planning and heat loss before a heat pump is designed. Historic houses such as Bignor Roman Villa, about 2.4 miles south-east, are a reminder that listed homes need consent before a heat pump goes in.
Duncton is about 10 miles north-east of Chichester, in West Sussex. Whether you are in the middle of Duncton or further out, our engineers cover air source heat pumps, from small jobs to large ones. 371 places in West Sussex are on our list. There’s also a page for Worthing, about 13 miles away.
The closest recent job we can point to from Duncton was on Lower Street, Pulborough (RH20), about 6 miles east: installing a Daikin multi-split system serving the restaurant dining area, the private function room and the bar area as part of a major refurbishment programme.
Duncton High Street and Willett Close and the roads off them are all inside our area. All of GU28 is covered.

Questions from Duncton
Is the heat pump grant available in Duncton?
Yes, the scheme covers homes in England, including Duncton, 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 I need planning permission for a heat pump in Duncton?
The answer turns on the property and where the outdoor unit would sit. Around 28 listed entries sit within 0.5 miles of central Duncton. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with Chichester council, which is typically the planning authority for Duncton.
Do you look at the job first?
Yes, every time. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
Which accreditations do you hold?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Can landlords and managing agents book you?
Yes. From a single let flat to offices, shops and public buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
How do you keep the place clean during the work?
We start with protection: 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.
What owners can safely do
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.
Never try to top up, release or handle refrigerant yourself. 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. If you suspect a leak, switch the system off and call us.
