How we handle air conditioning in Old Windsor
Single-room systems are typically £1,200–£2,200 + VAT, while a two-room multi-split is typically £2,800–£4,500 + VAT and three to five rooms £4,500–£8,500 + VAT. Supply, installation, commissioning and F-Gas documentation are all included, and commercial VRF systems are priced after a survey. Modern air conditioning heats as well as cools: 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.
The outdoor unit position is the biggest single decision: we balance airflow, noise, the pipe run and access for future servicing.
Homes around Old Windsor are mostly houses, many with gardens, which normally leaves room for an outdoor unit. The bigger questions are the wall construction and the route back to the consumer unit.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

Why deal with it now?
The outdoor unit’s position is worth getting right first time. Placing it well keeps noise away from bedrooms and boundaries and makes servicing easier, and it can make a difference to planning. It’s agreed on the survey, not on the day. Small faults tend to grow, so it’s worth dealing with them early.
Several rooms, units or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.

What affects the quote in Old Windsor
Every job gets its own quote. These are the things that affect it:
- How many units are involved
- The equipment or parts the job needs
- How far the pipework has to run, and where
No two properties are the same, so each one gets its own fixed-price quote. The system, the access, the pipe routes and the parts involved all make a difference.
Asking for a quote
To speed up the quote, send us:
- The outdoor side of the property, including any roof or flat area
- Your installation or service records
- The make and model of the system, from the label
Photos are the fastest route to a quote: 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.
Rented and managed buildings
If you look after several properties, we can plan visits across the portfolio and price them together. Every address has its own paperwork, so each one has its own history.
Larger air conditioning systems in buildings need more than servicing: 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.
The process
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. In a place like Old Windsor, parking is rarely an issue, but tell us about gates and access to the back of the property.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- Then the work: units up, pipes and drain run, and a new circuit where needed.
- Before it runs, the pipework is proved tight and put under vacuum.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Before we arrive
- Have the make and model of any existing unit to hand
- Let us know where we can park and unload
- Unlock any gate, garage or side passage we need

Advice
Your questions about air conditioning in Old Windsor
Will air conditioning in Old Windsor need planning permission?
It comes down to the building and the spot chosen for the outdoor unit. A conservation area takes in the middle of Old Windsor. 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 Windsor and Maidenhead council, which is normally the planning authority for Old Windsor.
Do you cover Old Windsor for air conditioning?
Yes. Old Windsor is one of the places we cover. To start, phone us on 07833 053749 or send an email with a few pictures.
How long does it take to fit air conditioning?
Most single-room systems take a day. Multi-split, ducted and cassette systems take longer and the quote says how long to expect.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Let us know who the records should go to.
Do you survey before quoting?
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.
Do you work on systems someone else installed?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Tell us the make and model and send any paperwork you have.
Where does the outdoor unit go?
Wall brackets, ground level and flat roofs are all options, wherever the pipe route, airflow and servicing access work best. We also think about noise near bedrooms and neighbours and position can affect planning.
Air conditioning around Old Windsor
About 40% of homes in the Old Windsor area date from 1945 to 1972, according to VOA council tax data, and about 76% of households live in detached or semi-detached houses, according to Census 2021 figures. Homes of that age typically have cavity or solid brick walls, and we check which before planning the pipe route. With homes like that, finding a sensible outdoor unit position is rarely hard, and a multi-split lets two or more rooms run off it.
Frogmore House, about 1.3 miles north-west, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it. Around St Luke, a quick check of the listing and conservation maps is part of planning any install.
