Air conditioning installation in Westminster costs 2,400 to 4,500 pounds for a single room, fitted and including VAT, and takes one day on site.
In Westminster the honest first question is not what it costs, it is whether the building will allow it. We give that answer for free, and sometimes it is no.
The housing stock in Westminster, and what it means for the job
Westminster is the most controlled environment we work in. Conservation area coverage is very high, listed buildings are common rather than exceptional, and the great majority of residential property is flats in mansion blocks or in converted period houses. That means almost every job here needs freeholder or managing agent consent and planning permission, and the position of the outdoor unit is decided by what is invisible from the street rather than by what is convenient.
The typical Westminster installation
A typical Westminster job is a mansion block flat where the outdoor unit goes into a light well or onto a flat roof section, with a full licence pack and a planning application handled before any date is agreed.

Permission in Westminster
Conservation area coverage in Westminster is high, so the first check on any address here is whether the street sits inside one. Inside a conservation area you keep permitted development rights, but the outdoor unit cannot go on a wall or roof slope fronting a highway, which in practice means the rear. Where the property is a flat, planning permission is needed regardless of any of that.
We check the conservation area boundary, any Article 4 direction and the listed building register for your exact address before quoting, and we tell you in writing what we find. We do not publish this council's individual position on this page, because we will not state a council's position we have not read. What we will do is confirm it for your property before you spend anything.

How much does air conditioning cost in Westminster?
2,400 to 4,500 pounds for a single room, before any freeholder or planning fees, which in central London are often the larger part of the total. A two-room system on one outdoor unit is typically 3,200 to 5,500 pounds, and three rooms 4,500 to 7,500 pounds.
Every price includes the units, installation, commissioning, electrical work and VAT. The fixed price comes after a free survey. There is a full breakdown on the cost page.
Do I need planning permission for air conditioning in Westminster?
Westminster has a high proportion of its area inside conservation areas, so the first thing to establish is whether your street is in one. If it is, you keep permitted development rights but the unit cannot go on a wall or roof slope fronting a highway, which normally means the rear. If your property is a flat, planning permission is required regardless, because flats sit outside permitted development for this work.
We check the conservation area boundary, any Article 4 direction and the listed building register for your specific address before we quote. The full set of conditions is on the planning permission page.
How quickly can you get to Westminster?
Forty to sixty minutes from Southgate, and the congestion charge and parking are planned into every Westminster job. For a survey we usually offer something within 48 hours, and for a fault call we will tell you the day we can genuinely attend rather than promising one we cannot keep.
Do you install in flats in Westminster?
Yes, and a large part of our work is flats. It takes two permissions rather than one: the freeholder's written consent and planning permission from the council. We prepare the licence pack the managing agent will ask for at no charge, including the drawing, the sound data and the insurance.
The order matters, and doing it in the wrong order is what makes flat installations expensive. There is a full sequence on the leasehold flats page.
