Walderton air source heat pumps
Air source heat pumps for Walderton and the surrounding area: a survey or diagnosis, a fixed price, careful work and proper paperwork. Call for a fixed-price quote.
- Working out whether radiators need upsizing
- Wanting to stop using oil, LPG or gas for heating
- Questions about where the outdoor unit can go
Why deal with it now?
A heat pump sized without a proper heat loss survey can struggle in cold weather or run inefficiently. Doing the survey properly from the start avoids that. A dirty or faulty system works harder and costs more to run.
What you pay depends on the type of system and how many units are involved, how easy the units are to reach and the parts and time the job needs. We give you a fixed price before we start, so you know where you stand.

Air source heat pumps for homes and businesses in Walderton
We install air source heat pumps in Walderton and across West Sussex, and we’re MCS certified. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We help you work out which suits your home. If you are dealing with checking whether planning permission is needed and deciding which kind of heat pump suits the home, we can help.
If your home in or near Walderton is heated by oil, LPG or electric heaters with no mains gas, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

Your questions about air source heat pumps in Walderton
Will you come out to Walderton?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Is the heat pump grant available in Walderton?
Walderton is covered, as the scheme runs across England and Wales. 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. We hold MCS certification, so the application is ours to make for you.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine from all the leading brands. Send us the make and model, and any records you have.
Will my radiators work with a heat pump?
The heat loss survey answers that, room by room. Rooms where the radiator is big enough stay as they are and any changes are in the quote.
Why use an F-Gas certified company?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.
When will I hear back?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
How does the warranty work?
It’s the manufacturer’s, and the terms are theirs. Some terms depend on regular servicing by a qualified engineer, so keep your service records.
Fixed-price quotes for air source heat pumps in Walderton
Every job gets its own quote. These are the things that affect it:
- Whether the existing supply is suitable
- What we find on the survey or diagnosis
- Which make and model is being fitted or worked on
The price reflects the work, not guesswork. That’s why every job is looked at first, and why the quote is fixed before we start.
What we need to know
Simple jobs can often be priced from photos and some basics. Send what you can of the following:
- The outside wall, roof or yard where the outdoor unit sits or would go
- Your consumer unit or fuse board
- The address and the type of property
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and many jobs can be priced from that.
Aftercare tips
To keep the system working properly:
- Ask about the grant before you commit
- Leave space around the outdoor unit
- Read the manufacturer’s warranty terms for your brand
Handover includes the controls and how to get the best from a heat pump. Heat pumps tend to work best running steadily rather than in short bursts, and we’ll explain the settings for your home.
Keep radiators and indoor units unobstructed so the heat can get into the room.

Air source heat pumps in Walderton: the local picture
About 76% of households live in detached or semi-detached houses, according to Census 2021 figures. Detached and semi-detached houses usually have room for the outdoor unit and a cylinder. Central Walderton is inside the Walderton Conservation Area. In the mile around Walderton’s centre, 2 conservation areas have been designated. Walderton House, listed at grade II, is one of roughly 8 protected buildings and structures in the half-mile around Walderton’s centre. For a heat pump, permitted development doesn’t apply within the grounds of a listed building, and in a conservation area the outdoor unit can’t go on a wall or roof facing a road, so we check with the planning team at Chichester council, which normally handles Walderton where necessary.
Live in one of the older houses around The Parish Church of St Mary? Expect the survey to look closely at heat loss and at the building’s planning status. If your home is listed, like Uppark about 4.3 miles north, listed building consent comes before any heat pump work.
Walderton is about 5 miles east of Havant, in West Sussex. From the centre of Walderton to the outskirts, our engineers cover air source heat pumps, from small jobs to large ones. Walderton is one of 371 towns, villages and districts in West Sussex where we work for homes and businesses. We also work in Worthing, around 21 miles away.
Not far from Walderton, a recent job of ours was on East Street, Chichester (PO19), about 6 miles south-east: installing a Daikin wall-mounted unit in the dining area and a second unit serving the kitchen pass area.
Here we cover the PO18 postcode area. If you are just outside Walderton, we cover Lordington (1 mile south-west), Racton (1 mile south-west), Funtington (2 miles south-east), Hambrook (2 miles south) and West Ashling (3 miles south-east).

The process
The visit goes in the diary at a time that works for you, and we let you know if plans need to move. 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 several days for an air-to-water system with a new cylinder, less for an air-to-air system. For a place like Walderton, 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.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- You get a fixed-price quote, with any grant you are eligible for and the VAT explained.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- The system is commissioned and registered under MCS, and we show you how to use it.
Getting ready for the visit
- Name a contact who can meet us at the agreed time
- Plan for pets to be kept clear during the visit
- Mention any managing agent or landlord rules we need to follow
