Air conditioning installation in Barnet costs 1,900 to 3,500 pounds for a single room, fitted and including VAT, and takes one day on site.
Hampstead Garden Suburb is one of the most tightly controlled areas in London for external alterations. If your address is inside it, that is the first thing to establish rather than the last.
The housing stock in Barnet, and what it means for the job
Barnet is really two boroughs for our purposes. North of the North Circular you get interwar semis and detached houses in Whetstone, Totteridge and Mill Hill, with side access and space, and those are straightforward jobs. South and west you get Hampstead Garden Suburb and the conservation areas around Golders Green and Hendon, where the appearance of the building is a live issue and the outdoor unit position needs real thought. Finchley adds a large stock of purpose-built 1930s flats, and those are the jobs where the freeholder question comes before everything else.
The typical Barnet installation
A common Barnet job is a two-unit multi-split serving a main bedroom and a loft conversion in a Finchley or Whetstone semi, with one outdoor unit on the rear elevation. Two days on site.

Permission in Barnet
Parts of Barnet are inside conservation areas and parts are not, so the answer genuinely depends on the street rather than on the borough. Outside a conservation area, a house installation that meets the Class G conditions needs no application at all. Inside one, the unit cannot face a highway.
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 We do not publish this council's individual position on this page, because we will not state a council's position we have not read.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 Barnet?
1,900 to 3,500 pounds for a single room in Barnet. Loft conversions, which are common here, usually need a 3.5kW rather than a 2.5kW unit. 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 Barnet?
In most of Barnet a domestic installation on a house is permitted development and needs no application, provided it meets all the Class G conditions. Parts of the borough are inside conservation areas, where the unit cannot face a highway. Flats need planning permission regardless.
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 Barnet?
Fifteen to thirty minutes from our base in Southgate, depending on which end of the borough. 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 Barnet?
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.
