Questions from Bilsham
Is the coast a problem for outdoor units in Bilsham?
It can. Bilsham is within about 2 miles of the coast, and salt air speeds up corrosion on outdoor units. The outdoor unit position, its fixings and regular servicing all help near the sea.
Will you come out to Bilsham?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and photos, and we reply the same working day.
Does servicing affect my warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Either way, keep a record of every service.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we have done.
Can I fit air conditioning or a heat pump myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
Is there VAT on a heat pump?
Heat pumps in homes carry 0% VAT until 31 March 2027, with 5% from 1 April 2027. Businesses pay the standard rate, and this is general information rather than tax advice.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Air source heat pumps for homes and businesses in Bilsham
We begin with a room-by-room heat loss survey. It shows how much heat each room needs on a cold day so the system is sized to match. Guesswork leads to systems that are too big or too small. The work covers hot water cylinders, air-to-water heat pumps and air-to-air heat pumps, and common reasons people get in touch are moving away from fossil-fuel heating and a boiler that’s getting old.
Homes around Bilsham usually have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. Keep it with the system’s paperwork, because it helps with any later warranty question.

Owner checks or an engineer?
Owners can handle the everyday basics: 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.
Don’t move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.
What we do, step by step
On the day, we arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts. The work itself takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Photos of the room and the outside of the property help us plan a visit to Bilsham.
- First, a chat about the property and your goals for the heating.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- We recommend air-to-water or air-to-air and check the grant position.
- The system is installed and connected to the controls.
- After commissioning, you get the MCS certificate and a handover.
Before we arrive
- Unlock any gate, garage or side passage we need
- Mention any roof access, ladders or high-level work
- Name a contact who can meet us at the agreed time
Getting a price
For a fixed-price quote, call 07833 053749 or send an email with the address and a few details about the rooms or units involved. A few pictures make it quicker. We reply to enquiries the same working day.
Advice
How the job changes from property to property
Outdoor unit position and planning
Flats have tighter limits, and an Article 4 direction can remove permitted development rights. Listed building consent is a separate matter, and we check the position for your property.
VAT on heat pumps
HMRC says most air conditioning units are air source heat pumps, but each case depends on the facts, so we confirm the VAT on your quote.
Air source heat pumps in Bilsham: the local picture
Bilsham lies within about 2 miles of the sea. Coastal sites are worth mentioning at the survey, as salt air affects the outdoor unit and its fixings. On the National Heritage List, around 4 entries fall within 0.5 miles of the middle of Bilsham; Hobbs Farmhouse (grade II) is one. That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where needed, we check with the planning team at Arun council, which normally handles Bilsham. About 39% of homes in Bilsham and the neighbourhoods around it have been built since 2000, according to VOA council tax data, and about 62% of households live in detached or semi-detached houses, according to the 2021 Census. Lower heat loss in recent homes often means a smaller heat pump and fewer radiator changes. 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 Bilsham Chapel? Expect the survey to look closely at heat loss and at the building’s planning status.
