Air conditioning around Lower Horncroft
About 43% of homes in Lower Horncroft and the neighbourhoods around it were built before 1919, according to Valuation Office Agency council tax records, and Census 2021 figures found about 73% of households in detached or semi-detached houses. Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. Detached and semi-detached houses typically have space for the outdoor unit, and several rooms can share one on a multi-split.
If your home is in one of the older streets near Church of St Agatha, it’s worth checking whether it’s listed or in a conservation area before an install. With historic houses such as Bignor Roman Villa about 2.2 miles south-west, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

We install leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. The survey ends with a recommendation and the reasons for it, along with the manufacturer’s warranty terms on your quote. When someone in Lower Horncroft asks us for air con, the first questions are typically price and who will fit it. We publish typical prices and do the refrigerant work as an F-Gas certified company.
Where the outdoor unit goes decides how quiet and tidy the job is: we balance airflow, noise, the pipe run and access for future servicing.
Space outside is rarely the problem in a place like Lower Horncroft. More often it’s the walls, the electrics and the length of the pipe run that need thinking about.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

How we price air conditioning
You will get a fixed price before work begins. It’s based on:
- A single visit or a regular plan
- Whether the existing supply is suitable
- The equipment or parts the job needs
Several rooms, units or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- Your consumer unit or fuse board
- The rating plate or label on any existing unit
- The postcode and whether it’s a home, flat or business
VAT is set out clearly on every quote, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it on the quote. To get one, call us on 07833 053749 or email us.
Lower Horncroft: your questions answered
Can I fit air conditioning in Lower Horncroft without planning permission?
That depends on the building and where the outdoor unit goes. The half-mile around the middle of Lower Horncroft holds about 17 listed buildings and structures. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask Chichester council, which is typically the planning authority for Lower Horncroft.
Will you come out to Lower Horncroft?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will tell you what to do first.
Do you look at the job first?
Yes. We always look before we price, on a survey, or from your photos and details where the job is simple. A fixed-price quote follows.
Can I use air conditioning to heat a room?
Yes, most modern split systems run as heat pumps, so they heat as well as cool. The Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. We confirm the heating function of the model we quote.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Can I do any of the installation myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
What happens on the day
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. Before we leave, the area is tidied and we explain what we’ve done. We agree a date with you and plan the visit to Lower Horncroft so we arrive with what’s needed.
- You send photos, or we visit and survey the rooms and outside.
- Output, positions and price are settled before anything is booked.
- We protect the area, then fit both halves of the system.
- Pipework, cable and drain are run, the circuit is connected and the pipework is pressure tested and evacuated.
- The system is commissioned, the controls explained and the F-Gas records handed over.
How to prepare
- Make sure we can reach the outdoor unit, or where it will go
- Mention any managing agent or landlord rules we need to follow
- Clear access to the fuse board

Advice
Leave it or put it right?
There’s a tax point for homes: HMRC zero-rates the installation of energy-saving materials in homes until 31 March 2027, after which the rate becomes 5%. Whether a particular system qualifies depends on the facts, so we confirm the VAT on your quote. This is general information, not tax advice. An early booking makes the visit to Lower Horncroft easier to arrange.
What you pay depends on the system and the number of rooms or units, the access and what the work involves. You get a fixed price before any work starts, so there are no surprises.
