Air source heat pumps for homes and businesses in Walberton
Every installation starts with a 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. If you are dealing with not knowing whether a grant applies and questions about where the outdoor unit can go, we can help.
Older and listed homes in villages like Walberton need extra care, and permitted development does not cover listed buildings, so consent comes first.
Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

Walberton questions
Can I fit a heat pump in Walberton without planning permission?
The answer turns on the property and where the outdoor unit would sit. Central Walberton sits inside the Walberton Village and Walberton Green Conservation Area. 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 planning department at Arun council, typically the authority for Walberton.
Is Walberton within the area you cover?
Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
What VAT do I pay on a heat pump?
Homes pay 0% VAT on a heat pump installation until 31 March 2027, then 5%. The relief does not cover businesses, and this is not tax advice.
Will I get records for the system?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. Before we leave, we clear up and run through the work with you.

For landlords and property managers
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We can quote either party and send the records to whoever needs them.
Portfolio owners often want one contractor and one number. We work across London and the South East, so work at different addresses can be planned together and kept to a regular schedule.
What happens on the day
The first job on site is protection: sheets over the floor and any furniture nearby, and we ask before moving anything. Then the electrics are made safe and the work begins. It takes a few days on site, depending on the cylinder, the radiators and the pipework involved, and we tidy up before we leave. Pictures of the space and where the outdoor unit could go let us plan the work in Walberton.
- You tell us about the home and what you want from a heat pump.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- We recommend air-to-water or air-to-air and check the grant position.
- The system is installed and connected to the controls.
- We commission it, complete the MCS certificate and show you how to use it.
Getting ready for the visit
- Let us know if the building has a permit or sign-in process
- Keep pets out of the rooms we’re working in
- Dig out any previous service or F-Gas records
Getting a price
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.

What we’re called out for in Walberton
Homes off the gas grid, heated by oil or LPG, are often good candidates to look at. The Boiler Upgrade Scheme includes an extra £1,500, until March 2027, for air source or ground source heat pumps in homes heated by oil or LPG with no mains gas where the home is eligible.
Common reasons people call us include:
- Comparing heat pump types
- Working out where a cylinder could go
- Ageing boilers that will need replacing
Every heat pump design starts with a room-by-room heat loss calculation.
Before you book anyone
- Whether the manufacturer’s warranty depends on regular servicing
- Whether anyone has checked the property or the system first

Heat pumps in Walberton: local notes
VOA council tax data show about 35% of homes in and around Walberton were built in 2000 or later, and the 2021 Census found about 71% of households in detached or semi-detached houses. Newer homes usually lose less heat, which tends to suit a heat pump well. Detached and semi-detached houses usually have room for the outdoor unit and a cylinder.
Live in one of the older houses around St Mary's Church? Expect the survey to look closely at heat loss and at the building’s planning status.

VAT on heat pumps
HMRC says most air conditioning units are air source heat pumps, but each case depends on the facts and the VAT is confirmed on your quote.
Outdoor unit position and planning
The outdoor unit needs a position with good airflow, a solid base and a sensible pipe route. Noise is part of the MCS 020(a) check, so we consider nearby homes too.
A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
