Air conditioning installation in Hounslow costs 2,400 to 3,200 pounds for a single room, fitted and including VAT, and takes one day on site.

Hounslow, Cranford and Isleworth sit under the Heathrow approach, which keeps a lot of windows shut on hot nights, and our solar job in the projects is in Brentford, TW8, on a flat roof with ballasted frames so nothing went through the membrane.

## The housing stock in Hounslow, and what it means for the job

Hounslow runs from some of the most sought-after streets in west London to some of the most ordinary, and the job changes with it. Chiswick is Victorian and Edwardian houses and mansion flats, Bedford Park and Strand-on-the-Green among them, with real conservation control. Brentford and Isleworth are river frontage now mostly new flats, with Victorian terraces behind. Hounslow, Heston, Cranford and Feltham are interwar semis and terraces, and a lot of them. 54 per cent of homes in the borough are houses, and away from Chiswick most of them have a garden and a side or rear position that makes the job simple.

## The typical Hounslow installation

A typical Hounslow job is an interwar semi in Heston or Feltham with one or two rooms on a ground-level outdoor unit, done in a day or two. In Chiswick it is more often a period flat and a consent pack.

## What it costs here

| Job | System | Installed price |
| --- | --- | --- |
| One bedroom | 2.5kW single split | £2,400 to £3,200 |
| Double bedroom | 3.5kW single split | £2,550 to £3,500 |
| One room in a flat | Consent pack included | £2,600 to £3,900 |
| Two rooms | 2 unit multi-split | £4,300 to £5,800 |
| Three rooms | 3 unit multi-split | £6,400 to £8,600 |
| Heat pump, three bedroom house | After the £7,500 grant | £5,700 to £8,700 |
| Annual service | Any make | £95 plus VAT |

Every figure on this site is an estimate built from the quotations we issued in 2026 and our own installation experience. It is not a quotation. The price you are given after the free survey is the price you pay.

## Permission in Hounslow

Parts of Hounslow 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 look the street up against the council's boundary map and any Article 4 direction before we quote.

## What the housing in Hounslow means for permission

Hounslow is close to evenly split: 54 per cent houses and 46 per cent flats. Most of our domestic work here is on houses and needs no planning application, provided it meets the Class G conditions. The flats, 37 per cent of homes in purpose-built blocks and 7 per cent in conversions, are the jobs that need a consent pack and a longer programme. The most common home in Hounslow is a flat in a purpose-built block, 37 per cent, which usually means a managing agent, a licence for alterations and a plant position the building decides. By share of houses it is in the upper half of the 21 boroughs we cover north of the Thames.

| Home type | Share of Hounslow | What it means here |
| --- | --- | --- |
| Detached | 5% | The easiest, with a choice of elevations |
| Semi-detached | 29% | Usually a side return, the best position there is |
| Terraced | 21% | No side access, so the rear or a bracket |
| Purpose-built flat | 37% | A large share here. Planning permission and freeholder consent, both |
| Converted flat | 7% | Two permissions, usually a smaller freeholder |

Shares of the 102,961 households counted in Hounslow at the 2021 Census, table TS044, rounded. Percentages do not total 100 because homes in commercial buildings and temporary structures are counted separately.

## Air conditioning in Hounslow: common questions

### How much does air conditioning cost in Hounslow?

2,400 to 3,200 pounds for a single room across Hounslow, with the Chiswick conservation-area jobs at the top of it. A two-room system on one outdoor unit is typically 4,300 to 5,800 pounds, and three rooms 6,400 to 8,600 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](https://climateshieldlondon.co.uk/air-conditioning-cost-london/).

### Do I need planning permission for air conditioning in Hounslow?

Most likely not. 54 per cent of homes in Hounslow are houses, and a house installation meeting the Class G conditions is permitted development.

The section further down this page sets out what the housing stock here means in practice, and every condition is on the [planning permission page](https://climateshieldlondon.co.uk/air-conditioning-planning-permission/). We check the conservation area boundary, any Article 4 direction and the listed building register for your exact address before quoting.

### How quickly can you get to Hounslow?

Forty five minutes to an hour from N14. Chiswick and Brentford are the quicker end, off the A406 and the M4. 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 Hounslow?

Yes. 46 per cent of homes in Hounslow are flats, 37 per cent of them purpose-built and 7 per cent conversions, so it is a large share of what we do here. 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 the two permissions are done in is what decides whether it is expensive, and there is a full sequence on the [leasehold flats page](https://climateshieldlondon.co.uk/air-conditioning-leasehold-flat/).

### Do you service and repair existing systems in Hounslow?

Yes, any make and any age, including systems installed by companies no longer trading. An annual service is 95 pounds plus VAT and a fault diagnosis is 89 pounds plus VAT, waived if we do the repair the same day. See [servicing](https://climateshieldlondon.co.uk/air-conditioning-servicing-london/) and [repairs](https://climateshieldlondon.co.uk/air-conditioning-repair-london/).
