Close to Heathrow, in Harlington, Hayes and West Drayton, a lot of people keep the windows shut on hot nights because of the aircraft. That is the whole case for a quiet system: it cools the room without the window having to be open. ### Read the full guide: 5 sections, about 3 minutes ## The housing stock in Hillingdon, and what it means for the job Hillingdon is the most suburban borough on our list. Ruislip, Eastcote, Ickenham and Northwood are Metro-land: interwar semis and detached houses built along the Metropolitan line, on wide plots with side access and long gardens, which is as close to an ideal outdoor unit position as London offers. Uxbridge adds older stock round the town centre and a lot of newer flats, and Hayes and West Drayton are interwar cottage estates, postwar terraces and the new blocks that went up around the Elizabeth line stations. Sixty nine per cent of homes here are houses, and a house with a side return and a garden is also exactly the property a heat pump is easiest to fit to. ## The typical Hillingdon installation A typical Hillingdon job is a Ruislip or Ickenham semi: two bedrooms on one outdoor unit in the side return, done in two days, and more often than anywhere else we work, a conversation about heating as well as cooling. ## 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 | | Two rooms | 2 unit multi-split | £4,300 to £5,800 | | Three rooms | 3 unit multi-split | £6,400 to £8,600 | | Whole house, four or five rooms | Multi-split, one or two outdoor | £8,400 to £14,000 | | 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 Hillingdon Parts of Hillingdon 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 Hillingdon means for permission 69 per cent of homes in Hillingdon are houses, which is high for London and is the main reason installations here tend to be straightforward. 14 per cent are detached and 35 per cent semi-detached, and a semi with a side return is close to the ideal outdoor unit position. Only 31 per cent are flats, and those are the ones that need planning permission and freeholder consent. The single most common home in Hillingdon is the semi-detached house, 35 per cent, and a semi with a side return is the best outdoor unit position there is. Of the 21 boroughs we cover north of the Thames, Hillingdon has the second highest share of houses. | Home type | Share of Hillingdon | What it means here | | --- | --- | --- | | Detached | 14% | The easiest, with a choice of elevations | | Semi-detached | 35% | The typical home here. A side return is the best position there is | | Terraced | 20% | No side access, so the rear or a bracket | | Purpose-built flat | 26% | Planning permission and freeholder consent, both | | Converted flat | 3% | Very few here | Shares of the 109,225 households counted in Hillingdon at the 2021 Census, table TS044, rounded. Percentages do not total 100 because homes in commercial buildings and temporary structures are counted separately. ### Postcodes we cover here HA4, HA6, UB3, UB4, UB7, UB8, UB10.

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 Hillingdon? Most likely not. 69 per cent of homes in Hillingdon 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 Hillingdon? Forty five minutes to an hour from N14 round the M25 or along the A40, so a Hillingdon job is booked as a full day with nothing squeezed in after it. 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 Hillingdon? Yes. 31 per cent of homes in Hillingdon are flats, 26 per cent of them purpose-built and 3 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 Hillingdon? 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.
