Air conditioning installation in Telegraph Hill
We fit wall-mounted splits, multi-split systems, ducted systems and ceiling cassettes, with VRF for larger buildings. Which one suits you depends on the space, the building and how much of the unit you want to see, and we explain the options on the survey. Most enquiries from Telegraph Hill start with one hot room: a bedroom, a home office or a loft conversion. That is normally a single wall-mounted split, from £1,200 + VAT.
Most installations here are a wall-mounted indoor unit, a short pipe run through the wall and an outdoor unit on the back or side of the property, with the drain run planned so it never drips where it shouldn’t.
Space outside is often tight in Telegraph Hill, as in much of London, which means a rear wall bracket, a flat roof or a balcony is often the best spot for the outdoor unit. Neighbours’ windows and noise matter as much as appearance when we choose the position, and the pipe run is planned to be short, neat and out of the way.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Each brand sets its own conditions, and we are happy to talk you through them.

Leave it or put it right?
Planning ahead beats a rushed decision in a heatwave. A rushed choice is often the wrong size or in the wrong place, and that’s hard to put right later. Booking the survey early gives you time to weigh up the options. Getting the work done in Telegraph Hill before summer avoids the busiest weeks.
Homes, offices, shops and public buildings are all priced the same way: what’s needed, how we reach it, the parts and the labour. Call for a fixed-price quote and we’ll go through it with you.

The process
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs attention later is pointed out. The visit takes a day or more, depending on the number of rooms, the pipe routes and the access. A note on parking and access helps us plan a visit to Telegraph Hill.
- 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.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- 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.
Preparing for the visit
- Tell us about any building rules, permits or sign-in
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Let us know where the consumer unit is

How the job changes from property to property
Offices, shops and commercial rooms
Systems over 12 kW of effective rated output bring extra duties for the building, such as a TM44 inspection by an accredited energy assessor at least every 5 years. We can arrange and prepare for it.
Multi-split systems
A multi-split runs several indoor units from one outdoor unit. It’s a neat answer when space outside is limited and several rooms need it, with each room controlled separately.
Before you call an engineer
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo or a short video of the display is even better.
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
Common questions in Telegraph Hill
Can I have air conditioning in a flat in Telegraph Hill?
Normally, yes, though leaseholders normally need the freeholder’s agreement. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Do you cover Telegraph Hill for air conditioning?
Yes. Telegraph Hill is one of the places we cover. Just phone us on 07833 053749 or drop us a line with a few details.
How long does air conditioning installation take?
It takes about a day for a single-room system, longer for multi-room and ducted systems. The survey tells us how long your installation will need so there are no surprises.
Can I fit air conditioning or a heat pump myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We’re happy to quote for the full job, supply to commissioning.
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Do I need to service the system to keep the warranty?
Each manufacturer decides. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
Who is responsible for leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Homes in Telegraph Hill and air conditioning
About 49% of homes in Telegraph Hill and the neighbourhoods around it were built before 1919, according to the Valuation Office Agency’s council tax figures, and the last census (2021) found about 67% of households live in flats. Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can. In flats, the lease and the freeholder usually decide where an outdoor unit can go, and the permitted development rules for flats are tighter. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.
Around St Catherine's Hatcham, a quick check of the listing and conservation maps is part of planning any install. If you work from home near Brockley station, a home office that overheats is one of the easiest rooms to cool.

A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
