Air conditioning for period and prime London homes

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.

01 / The gap

An installation is finished when the room is, not when the system switches on.

02 / Approach

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.

You contract with LOAM for the whole job. The installation is carried out and certified by one of our F Gas certified installation partners, and our finishing trades then make good and decorate. You get one contract, one fixed price and one point of contact.

Designed

By interior designers

Unit positions, grille details and cornice implications are settled by BOMA's design team before a price is put to them.

Installed

By F Gas certified engineers

We partner with specialist installation firms who work in prime residential every week. Each holds its own F Gas company certificate and certifies the systems it installs.

Finished

By finishing trades

Art Contractors fill, skim, sand and decorate, to the standard the rest of the house is held to.

03 / Method

How an installation runs.

Six stages. You know what happens, what it costs and when it happens before anyone lifts a floorboard.

01

Property visit

We walk the house with you, together with our installation partner. Rooms, orientation, glazing, ceiling voids, the routes a pipe could take and the ones it never should.

02

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.

03

Technical review

Heat loads, pipe runs, condensate, power and acoustics, plus where listed consent, conservation area or freeholder approval will be needed.

04

Proposal

One fixed price against a defined scope. Equipment schedule, the finishing work included, and a plain list of what sits outside it.

05

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.

06

Installation and finish

Our installation partner installs and commissions the system, then our finishing trades make good. Chases filled, walls skimmed, decoration completed. We hand back a finished room, not a working system.

04 / Scope

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
05 / Included

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.

You contract with LOAM for the whole job, from the first visit to the final coat of paint. Installation is carried out by our F Gas certified partners, working under our contract. One agreement, one price, one point of contact.

06 / Questions

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?

LOAM manages the job and holds your contract. Installation and commissioning are carried out by one of our F Gas certified partners, and making good and decoration by Art Contractors. Your proposal names the installer, so you know who is on site from first fix to final coat.

Who certifies the installation?

The installation partner on your job. They hold the F Gas company certificate, commission the system, register the manufacturer's warranty to your property and issue the installation certificate at handover. We confirm their certification before any work starts.

Who looks after it afterwards?

At handover you can take out an annual service plan directly with the installer who fitted your system. It covers filter and coil cleaning, refrigerant and condensate checks, and keeps the manufacturer's warranty valid. Our workmanship warranty covers the finished job.

07 / Next step

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.
