About our air source heat pumps in Halnaker
Every installation starts with a heat loss survey. That tells us how much heat the home needs, room by room so the system is sized to match. Guesswork leads to systems that are too big or too small. Common call-outs are for ageing boilers that will need replacing and planning and permitted development questions, on homes heated by oil, LPG or gas, air-to-air heat pumps and air-to-water heat pumps.
Older and listed homes in villages like Halnaker need extra care, because permitted development doesn’t apply within the grounds of a listed building, so we check consent first.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

When to call us in Halnaker
The Boiler Upgrade Scheme has made people ask whether their home could qualify. Eligibility depends on the property, the system and the scheme rules, so we check before you commit.
If any of these sounds familiar, it’s worth a diagnosis:
- Not knowing whether a grant applies
- Questions about where the outdoor unit can go
- Working out where a cylinder could go
If your home is one of the older properties near The Priory Church of St Mary and St Blaize, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

- Whether the company is F-Gas certified, and whether you can check it
What affects the quote in Halnaker
Some jobs are bigger than they look, and some smaller. What affects the quote:
- What electrical work the job needs
- What state the existing equipment is in
- The distance and route between the indoor and outdoor units
A single unit or a whole estate, we price it on the same basis: what needs doing, how we get to it and what it needs. The price is fixed before any work starts, with VAT shown clearly.
Helping us quote
To speed up the quote, send us:
- A few pictures of the room and the wall the unit is on, or will go on
- Any previous service or F-Gas records
- The outdoor side of the property, including any roof or flat area
To get a fixed-price quote, phone 07833 053749 or drop us a line and tell us about the property and what you need. A few pictures make it quicker. We reply to enquiries the same working day.
Homes in Halnaker and heat pumps
Census 2021 figures found about 71% of households in detached or semi-detached houses. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
If your home is listed, like Goodwood House about 1.4 miles west, listed building consent comes before any heat pump work.

FAQs for Halnaker
Can I fit a heat pump in Halnaker without planning permission?
That depends on the building and where the outdoor unit goes. There’s a conservation area, the Halnaker Conservation Area, close to central Halnaker. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit cannot face a road. Where necessary, we check with the planning department at Chichester council, typically the authority for Halnaker.
Do you cover smaller places like Halnaker?
We do. Villages and hamlets get the same service as the bigger towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you work on systems someone else installed?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Send us the make and model, and any records you have.
Which type of heat pump is right for my home?
It depends on your home, your heating and whether you want cooling. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions, and we set out the options after the survey.
Do I need new radiators for 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 that need upsizing are set out in the quote.
Is there a Boiler Upgrade Scheme grant for air-to-air?
A £2,500 grant is available in some cases. It won’t apply if the system is an add-on next to a boiler as it has to meet the full heating demand.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Every visit is recorded and F-Gas records kept where they apply.
