### One company, one team, one set of paperwork

Climate Shield London is Electro Heating Limited, and the engineers who quote the job are the engineers who do it. Ten years of London installations, one set of insurance and one set of certificates, which is why a job that turns out to need a heat pump rather than a split system does not need a second contractor and a second quotation.

### We will tell you when the answer is no

A first floor flat with a boundary two metres away, a listed frontage, a freeholder who has refused three times already: these come up every week. Where the job is not lawful or not viable we say so on the survey rather than taking a deposit and finding out later. It costs us a sale and it is the reason the reviews we do have are real.

### The price is written before anyone starts

Every quotation says what is included and what is not. It does not move unless the scope moves, and if we find something behind a wall that nobody could have seen, we tell you before we do the work and you decide.

## One box outside, cooling, heating and hot water

Most London terraces have room for exactly one outdoor unit. These systems do all three jobs from it, and almost nobody here fits them.

Ask if your house suits one [How it works](https://climateshieldlondon.co.uk/air-to-air-heat-pump-london/)

![Air source heat pump outdoor unit installed beside a house](https://climateshieldlondon.co.uk/assets/img/geh/heat-pump-700.webp)

### Integrated air to air and air to water

Samsung Quint, Daikin Altherma X

One outdoor unit driving both the wall units that cool your rooms and the radiators, underfloor and cylinder that heat the house. It replaces the gas boiler and the air conditioning in the same install.

![Hot water cylinder and system controls installed in a plant cupboard](https://climateshieldlondon.co.uk/assets/img/geh/controls-700.webp)

### Air conditioning that makes your hot water

Daikin Multi Plus

A multi split that cools two or three rooms and produces the domestic hot water from the same outdoor unit. The heat it takes out of your bedroom in August goes into the cylinder instead of into the street.

## The three things people ask before the price

![Outdoor air conditioning unit on wall brackets above brick, with isolator switch and pipework in trunking](https://climateshieldlondon.co.uk/assets/img/jobs/job-04-800.webp)

### Do I need planning permission?

Usually no, sometimes yes, and in a conservation area it is a different conversation entirely. All eight conditions are in one table.

[Read the rules](https://climateshieldlondon.co.uk/air-conditioning-planning-permission/)

![Engineer holding the controller beside a wall-mounted indoor unit above a sofa](https://climateshieldlondon.co.uk/assets/img/jobs/job-05-800.webp)

### What will it cost to run?

About 12 to 30 pence an hour for a typical bedroom on a hot day, and less once it has pulled the room down and starts cycling.

[See the running cost](https://climateshieldlondon.co.uk/air-conditioning-running-costs/)

![Matte black indoor air conditioning unit on a white wall in a period room](https://climateshieldlondon.co.uk/assets/img/jobs/job-08-800.webp)

### Will it ruin how the room looks?

It does not have to. Units come in matte black as well as white, and where the room deserves it a ceiling cassette disappears completely.

## How the job runs

Nothing is charged until the price is agreed in writing.

1. You call or messageTwo minutes. Tell us the postcode, the rooms and roughly what you want. We say straight away if it is a job we should be doing.

## Questions people actually search

### Do I need planning permission to install air conditioning in London?

In most cases no. A domestic outdoor unit is normally permitted development in England, which means no planning application, provided it meets a short list of conditions: one unit only, at least one metre from the boundary if it is on a wall or roof, not on a wall facing a highway forward of the principal elevation, not above the highest part of the roof, and quiet enough to meet the MCS 020 noise standard.

London breaks that more often than anywhere else, because London has more conservation areas, more listed buildings and more flats. Every condition is set out on the [planning permission page](https://climateshieldlondon.co.uk/air-conditioning-planning-permission/).

### How much does air conditioning cost to install in London?

A single room wall-mounted split system, supplied and fitted with VAT, is typically 2,400 to 3,200 pounds in London. A two-room multi-split on one outdoor unit is typically 4,300 to 5,800 pounds, and a three-room system 6,400 to 8,600 pounds.

What moves the number is access, pipe length and electrics rather than the unit itself. The full breakdown and a calculator are on the [installation cost page](https://climateshieldlondon.co.uk/air-conditioning-cost-london/).

### Can I put air conditioning in a leasehold flat?

Usually yes, but you need the freeholder's written consent before anything else, because the outdoor unit changes the exterior of the building and almost every London lease restricts that. Planning permission is a separate question and it comes second.

We give you the drawing, the unit specification and the noise data the managing agent will ask for, at no charge. There is a full order of events on the [leasehold flats page](https://climateshieldlondon.co.uk/air-conditioning-leasehold-flat/).

### Does air conditioning also heat the room in winter?

Yes. Every system we fit is a reversible air-to-air heat pump, so the unit that cools in August heats in February. It moves heat rather than making it, which is why it returns roughly three to four units of heat per unit of electricity.

That makes it the cheapest way to heat one room that most London homes have, and it is why a lot of customers who bought it for summer end up using it more in winter.

### Is there a government grant for air conditioning?

That changed in 2026 and a lot of pages still say otherwise, including this one until recently. The Boiler Upgrade Scheme pays 7,500 pounds towards an air-to-water heat pump, which heats radiators and hot water, and it now also lists 2,500 pounds towards an air-to-air heat pump, which is what an air conditioner is.

Since 2026 the Boiler Upgrade Scheme also lists 2,500 pounds towards an air-to-air heat pump, which is what an air conditioner is. It is not the same as the 7,500 pound grant for an air-to-water heat pump and the conditions are narrower: it depends on what is being replaced, on the property having a valid EPC, and on an MCS certified installation. We will check whether your property qualifies and tell you either way, and we will not put a grant in a quotation until it is confirmed. The current rules are on [GOV.UK](https://www.gov.uk/apply-boiler-upgrade-scheme/what-you-can-get).

There is a full page on it: [is there a grant for air conditioning](https://climateshieldlondon.co.uk/air-conditioning-grant-uk/), including what is verified and what is not.

If the grant is what you are after, that is an [air source heat pump](https://climateshieldlondon.co.uk/air-source-heat-pumps-london/), and we install those too.

### How long does an installation take?

One day for a single room in a typical north London house, including commissioning and handover. A two or three room system on one outdoor unit is usually two days.

We work in one property at a time rather than starting four and finishing none, so the date you are given is the date the work happens.

### Do you work on car air conditioning?

No. This is building air conditioning only, for homes and commercial premises. Vehicle air conditioning is a separate trade with separate qualifications and we would be no good at it.

### Which areas of London do you cover?

All of Greater London, with a north London focus. We are based in N14, so Barnet, Enfield and Haringey are our nearest work and usually the quickest to book. There is a page per area on the [areas we cover](https://climateshieldlondon.co.uk/areas/) page.
