Thinking about air conditioning but not sure where to start? Send a few pictures of the rooms and the outside walls when you give us a ring on 07833 053749 or use the quote form, and you will hear back from us the same working day about a survey or a fixed-price quote. Most split systems we fit in Delly End are reversible: the Energy Saving Trust notes that air-to-air heat pumps are sometimes called air conditioning, so a system bought for summer earns its keep in winter too.
Homes around Delly End normally have room outside for an outdoor unit. More often it’s the walls, the electrics and the length of the pipe run that need thinking about.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

Homes in Delly End and air conditioning
The last census (2021) found about 81% of households in detached or semi-detached houses. 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 John the Evangelist, it’s worth checking whether it’s listed or in a conservation area before an install. About 2.2 miles south-west stands Minster Lovell Hall. Listed homes in any area need consent first, so tell us if yours is one.
Delly End is about 2 miles north of Witney, in Oxfordshire. Anywhere in OX29, we cover air conditioning. Our Oxfordshire coverage runs to 443 places, Delly End among them. Guildford is in our area too, around 56 miles away.

Around Delly End
Locally, jobs take us to houses, flats and workplaces close to The King's School, The Lamb And Flag Public House and Wood Green School and the streets around them. The nearest railway station is Finstock station, roughly 2.6 miles north of the centre. Well-known places in the area include Cogges Manor Farm Museum (2.3 miles south). Not far away are Blenheim Farm.
Let and managed properties
Bigger systems bring extra duties: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We arrange the inspection, get the system ready and put right anything it picks up.
Running several properties is easier with one contractor. Our area covers Greater London and the South East, so work at different addresses can be planned together and kept on a regular cycle.
Keeping the system healthy
Looking after it is simple, and it helps at the next service:
- Choose a comfortable set temperature rather than the lowest
- Clean the filters every few weeks when the system is in heavy use
- Keep to the service interval the manufacturer recommends
You get the paperwork that matters: F-Gas records, commissioning details and the manufacturer’s warranty terms. File them together, because the manufacturer or a future engineer may ask to see them.
Give the outdoor unit room to breathe. Leaves, plants, bins and stored items around it restrict the airflow, which makes the whole system less efficient.

What else we do in Delly End
Questions from Delly End
Will air conditioning in Delly End need planning permission?
It comes down to the building and the spot chosen for the outdoor unit. The centre of Delly End is in the Hailey Conservation Area. Permitted development only covers heat pumps that are not used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where necessary, we check with West Oxfordshire council, which is typically the planning authority for Delly End.
Can you do air conditioning in Delly End?
We do: Delly End falls inside our working area. Just phone 07833 053749 or drop us a line with a few details.
Will you need to do electrical work?
Usually, yes. The fuse board is checked on the survey, and any electrical work goes on the quote and we install and certify the circuit as NICEIC approved contractors.
What accreditations do you have?
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.
Is there a survey before the work?
Yes. We always look before we price, on a survey, or from your photos and details where the job is simple. Then you get a fixed-price quote.
Should I choose wall-mounted, ducted or cassette?
There’s no single best type. A split suits one room, a multi-split several, a ducted system hides the unit, and a cassette spreads air across larger rooms. The survey ends with a recommendation and the reasons.
How much is air conditioning for one room?
A single-room split system is typically £1,200–£2,200 + VAT. A two-room multi-split is typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT, including supply, installation, commissioning and F-Gas documentation. You get a fixed price before any work starts.
Why deal with it now?
There’s a tax point for homes: installing energy-saving materials in residential accommodation is zero-rated until 31 March 2027, then 5%. HMRC says most air conditioning units are air source heat pumps, but each case depends on the facts, so we confirm the VAT on your quote. This is general information, not tax advice. A dirty or faulty system works harder and costs more to run.
Height, access and the distance between the indoor and outdoor units all affect the cost. We take each of them into account and give you a fixed price before any work starts.

What happens on the day
Testing is the last part of the visit wherever the system can be switched on. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. The visit takes anything from a day for one room to several days for a multi-room or ducted system. We plan the trip to Delly End around you.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- Then the work: units up, pipes and drain run, and a new circuit where needed.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
How to prepare
- Let us know if the units are on a roof, a high wall or in a locked area
- Arrange for someone to be there to let us in
- Find the manual or the paperwork for the system, if you have it
Ask for a quote
The quickest way to a quote is to send pictures: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and many jobs can be priced from that.
