When to call us in Lower Horncroft
Extensions, renovations and loft conversions are a natural time to rethink the heating. It’s simpler to plan radiators, pipework and a cylinder while the builders are in.
Most people get in touch after spotting something like this:
- An oil, LPG or gas boiler near the end of its life
- Questions about listed buildings or conservation areas
- Deciding on the outdoor unit position
Older homes near Church of St Agatha may need extra checks for planning and heat loss before a heat pump is designed.
What to look for in a quote
- Who does the electrical work, and whether they can certify it
- What’s in the price and what isn’t
- Whether you get F-Gas records where refrigerant is involved
How we handle air source heat pumps in Lower Horncroft
Installing an air source heat pump in a home is zero-rated for VAT until 31 March 2027, then 5%. This is HMRC’s energy-saving materials relief, which applies to homes rather than businesses. For air-to-air systems, we confirm the VAT on your quote. This is general information, not tax advice. The work covers radiator systems, air-to-water heat pumps and hot water cylinders, and the jobs we see most are working out whether radiators need upsizing and deciding on the outdoor unit position.
Space for an outdoor unit is rarely an issue near Lower Horncroft, so the design focuses on heat loss and radiators.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

How it works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. On site, it takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Somewhere like Lower Horncroft, it helps to know about lanes, gates and where to park.
- We start with your plans and the property.
- 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.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
How to prepare
- Tell us about parking and loading
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Have the make and model of any existing unit to hand
Getting a quote
To help us quote: where the property is and what kind of building it is, pictures of the rooms or units, the make and model of any existing system and anything you’ve noticed, such as an error code or a noise. Once you have those, call 07833 053749 or write to us at info@aircondoctor.co.uk.

Air source heat pumps around Lower Horncroft
In the mile around Lower Horncroft’s centre, 2 conservation areas have been designated. Kate's Cottage and Tripp Hill Cottage, listed at grade II, is one of roughly 17 protected buildings and structures in the half-mile around Lower Horncroft’s centre. For a heat pump, permitted development does not apply within the grounds of a listed building, and in a conservation area the outdoor unit cannot go on a wall or roof facing a road, so we check with Chichester council, usually the planning authority here where necessary. VOA council tax data put about 43% of homes in Lower Horncroft and the neighbourhoods around it before 1919, and about 73% of households live in detached or semi-detached houses, according to the 2021 Census. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.
Historic houses such as Bignor Roman Villa, about 2.2 miles south-west, are a reminder that listed homes need consent before a heat pump goes in.

Lower Horncroft questions
Do you cover smaller places like Lower Horncroft?
Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.
Can I get the Boiler Upgrade Scheme grant in Lower Horncroft?
Lower Horncroft is in England, where the Boiler Upgrade Scheme runs. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. As an MCS certified installer, we apply for it on your behalf.
Do you work on all makes?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
What’s the price of a heat pump installation?
£8,000–£16,000 (0% VAT on homes) for air-to-water, before the grant. Your price depends on the survey, the emitters and the hot water, and you get a fixed-price quote.
Do you have a 24/7 line?
Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll agree what happens next.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it and the fixed price is built on it.
