About our air source heat pumps in Lyminster
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. Please treat this as general information rather than tax advice. If the problem is finding a place for the outdoor unit and planning and permitted development questions, we can sort it out.
Space for an outdoor unit is rarely an issue near Lyminster, so the design focuses on heat loss and radiators.
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 happens on the day
We book the visit for a day and time that suit you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your photos or the details you gave us. If something is different, we talk it through with you before carrying on. After that, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. If a lane or gateway near Lyminster is tight for a van, let us know and we’ll plan for it.
- We find out about your home and the heating you have now.
- A heat loss survey is carried out, room by room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Installation, commissioning and MCS registration complete the job.
How to prepare
- Clear the space around the indoor unit, or where it will go
- Let us know where the consumer unit is
- Keep pets and children away from the work area

Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from pictures and measurements. After that, we send a fixed price before any work starts.
Related advice
What owners can safely do
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo or a short video of the display is even better.
FAQs for Lyminster
Can I fit a heat pump in Lyminster without planning permission?
It depends on the property. There’s a conservation area, the Lyminster Conservation Area, close to central Lyminster. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with the local planning authority (for Lyminster, typically Arun council) first.
Does the Boiler Upgrade Scheme cover homes in Lyminster?
Lyminster is in England, where the Boiler Upgrade Scheme runs. 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. You don’t apply yourself: the MCS certified installer does, which is us.
Are my radiators big enough for a heat pump?
We find out during the survey. Where a radiator is already large enough, it stays and any changes are in the quote.
How does the warranty work?
Warranty comes from the manufacturer and depends on the brand and product. Daikin, for instance, gives a standard 2 years on split air conditioning and we explain the terms for your brand on the quote.
Which brands do you work with?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Do I get paperwork after the visit?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
What does an air-to-water heat pump cost?
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes) before the grant. The Boiler Upgrade Scheme offers £7,500 to eligible homes in England and Wales though not every home qualifies.

Aftercare tips
After the visit, a few habits help:
- Read the manufacturer’s warranty terms for your brand
- Leave indoor units unobstructed
- Let the heat pump run steadily, as set up at handover
If anything doesn’t seem right after installation, phone us on 07833 053749 or use the quote form and we will talk it through. Annual servicing helps keep the system working well.
Let the heat pump run steadily rather than switching it on and off as explained at handover.
Homes in Lyminster and heat pumps
Lyminster is within about 2 miles of the coast. Coastal sites are worth mentioning at the survey, as salt air affects the outdoor unit and its fixings. The Valuation Office Agency’s council tax figures show about 41% of homes in the Lyminster area were built in 2000 or later. Newer homes typically lose less heat, which tends to suit a heat pump well.
If your home is one of the older properties near The Parish Church of St Mary Magdalen, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. With Ecclesden Manor about 3.3 miles east, it’s worth asking whether your own home is listed before planning a heat pump.
