Ducted air conditioning in London hides the indoor unit and uses grilles, which suits buyers who refuse wall heads in period rooms. It still needs an outdoor condenser, a void or loft, a return-air path and a hatch. London labour, parking, leasehold consent and shallow joists routinely push cost above a wall split. Ducted air conditioning London searches should start with whether the ceiling can actually take ducts. If it cannot, a well placed wall unit is the honest design, not a failed promise of invisible air.
London fabric is the constraint
Georgian and Victorian floors, listed cornices, concrete flats and converted warehouses each kill or enable ducted work in different ways. A void that exists in a new rear extension may not exist in the front parlour.
Conservation areas and listed buildings add consent. The outdoor is still the planning problem even when the indoor disappears.
- Survey joist depth before promising no wall units.
- Plan return air with bedroom doors shut.
- Budget parking, skips and making good.
- Keep hatches off ornate ceilings where possible.
Flats versus houses
Mansion blocks and new-build apartments may have landlord rules that ban both ducts in common voids and condensers on facades. A house with a loft can be easier.

Cost shape
Builders' work dominates. Use the ducted UK cost discussion as a floor, then add London access. A ducted scheme that requires a full ceiling rip in a finished reception is rarely the bargain it looked like on a mood board.
Compare a Stylish or standard wall unit on the same rooms before you commit.
When to stay with wall splits
Occupied homes, shallow joists, and 'we cannot have dust for six weeks'. Invisible air is a renovation product.
If several floors need cooling and outdoor space is one rear yard, a multi-split with wall heads may still beat ducted on disruption.
Frequently asked questions
How much does ducted air conditioning cost in London?
More than a comparable wall split once voids, decorating and access are included, and often into five figures for several rooms. Only a surveyed quote with builders' work listed is a price.
Can I have ducted AC in a listed London house?
Sometimes, with the right consents and a design that protects fabric. The outdoor and any visible grilles still need thought. Do not assume permitted development covers it.
Is ducted quieter for London neighbours?
Indoor grilles can be discreet. The outdoor still makes noise. Neighbour impact is mostly the condenser, not the grille.
