What happens on the day
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and the rest is down to us. At the end, we tidy up and run through the work with you. A note on how to find the property and where to park makes a visit to West Marden easier.
- First we find out about the property, the heating you have now and what you’re hoping for.
- 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.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- The system is commissioned and registered under MCS, and we show you how to use it.
Preparing for the visit
- Mention any roof access, ladders or high-level work
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Keep pets and children away from the work area

Advice
How we handle air source heat pumps in West Marden
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 cannot 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. If you’re dealing with not knowing whether a grant applies and no space for a hot water cylinder, we can sort it out.
In a place like West Marden, some homes are listed, and permitted development doesn’t cover listed buildings, so consent comes first.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Rented and managed buildings
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed-price quote.
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We can quote either party, and the paperwork can go to both.

How the job changes from property to property
VAT on heat pumps
Heat pumps in homes carry 0% VAT until 31 March 2027, and 5% after that, under HMRC Notice 708/6. Businesses pay the standard rate.
Heat loss surveys
Getting the survey right avoids undersized or oversized systems, and both cause problems.
Common questions in West Marden
Will you come out to West Marden?
Yes, and the size of the place makes no difference to how we work. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is planning permission needed for a heat pump in West Marden?
It depends on the property. There’s a conservation area, the West Marden Conservation Area, close to central West Marden. 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 the local planning authority (for West Marden, usually Chichester council).
Can I get a grant for an air-to-air heat pump?
The scheme offers £2,500 for air-to-air, but the conditions are strict. Adding air-to-air alongside a boiler does not qualify, and it must cover the whole heating demand.
Can landlords and managing agents book you?
Yes. From one rented home to commercial buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
Will you work on another installer’s system?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Do you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and explain why.
Is the equipment covered by a warranty?
The manufacturer’s warranty, on the manufacturer’s terms. Each brand sets its own conditions and periods, so we explain them on your quote.
When to call us in West Marden
Some homes heated by electric heaters or storage heaters consider a heat pump instead. The survey tells you whether it’s practical and what’s involved along with whether any grant could apply.
Customers normally contact us after spotting one of these:
- Checking emitters for a heat pump
- Questions about the Boiler Upgrade Scheme
- A boiler that is getting old
If your home is listed, like Uppark about 2.6 miles north, listed building consent comes before any heat pump work.
Before you book anyone
- Why the equipment they’re quoting suits the job
- What’s in the price and what is not
- Whether you get F-Gas records where refrigerant is involved
