We put air conditioning into houses that were never built for it.
Listed, Georgian and Victorian, mostly in prime London. We design it around the ceilings, cornicing and joinery, not the other way round. Then we plaster, decorate and leave.

An installation is finished when the room is, not when the system switches on.
Installers don't decorate. Decorators don't install.
The usual route leaves that part with you. An installer hands back bare chased walls, a decorator is found weeks later, and nobody ever owned the look of the finished room.
Air conditioning in a period house is an interior decision before it is a technical one. Where a unit sits, where pipework runs, how the wall reads afterwards. Those choices set how a room feels for the next twenty years.
We hold the design of the installation and the finish of the room as one job, done by one team, priced as one number.
By interior designers
Unit positions, grille details and cornice implications are settled by BOMA's design team before a price is put to them.
By refrigeration specialists
F Gas certified engineers who work in prime residential every week, not in offices and retail units.
By finishing trades
Art Contractors fill, skim, sand and decorate, to the standard the rest of the house is held to.
How an installation runs.
Six stages. You know what happens, what it costs and when it happens before anyone lifts a floorboard.
Property visit
We walk the house with you. Rooms, orientation, glazing, ceiling voids, the routes a pipe could take and the ones it never should.
Design review
Where equipment lives so the room still reads as a room. Unit positions, grille details, joinery and cornice implications, settled before anything is priced.
Technical review
Heat loads, pipe runs, condensate, power and acoustics, plus where listed consent, conservation area or freeholder approval will be needed.
Proposal
One fixed price against a defined scope. Equipment schedule, the finishing work included, and a plain list of what sits outside it.
Scope of works and programme
A written schedule of works and a dated programme. Who is on site, on which days, and the state the house is left in each evening.
Installation and finish
Install, commission, then make good. Chases filled, walls skimmed, decoration completed. We hand back a finished room, not a working system.
Climate, then Finish.
Climate
Sized properly and run quietly. Heat loads calculated room by room, equipment chosen for noise as much as output, and condensate, power and pipe routes resolved on paper before anyone opens a wall.
- Room-by-room load calculations
- Equipment schedule with noise ratings
- Commissioning and handover pack
Finish
Chases filled, skimmed, sanded and decorated. Cornices reinstated, grilles set flush and painted in, boards relaid and floors cleaned. The room goes back the way it ought to look.
- Plastering and making good
- Cornice and joinery reinstatement
- Decoration to a high standard
Built for houses that were never meant to have it.
Most of our work is retrofit. Solid walls, lath and plaster, cornices worth keeping, and consent conditions that rule out the obvious answer. Knowing the building is as much of the job as knowing the equipment.
We sell direct to owners. There is no main contractor between you and the people doing the work.
Before you commit.
Can I have air conditioning in a listed building?
Often, yes. It depends on the grade, the fabric and your local authority, and it is something we assess properly at technical review rather than assume either way. Most of our work is in listed and conservation area properties.
How disruptive is the installation?
Retrofitting a single room takes about two weeks from start to finish. You get dated stages up front, one point of contact throughout, and the house left clean at the end of every day.
Do you handle the decoration as well?
Yes. Making good and decoration sit inside the scope and inside the price. It is not a separate trade you have to find, brief and chase once we have gone.
Who actually does the work?
A small, consistent group of engineers and finishers we work with directly, each holding their own F Gas certification. The same faces on your job from first fix to final coat.
Start with a property visit.
An hour in the house, no charge and no obligation. You will leave it knowing whether the installation you want is possible, and roughly what it costs.
Send the form and we will come back to you the same working day, usually with a call to talk through the house before anyone visits.
