Shop and Retail Air Conditioning

A shop can get hot quickly. Lighting, display screens, customers and staff all add heat, and a large shop window lets in the sun. A shop that is too warm is uncomfortable for customers and staff alike. Air conditioning keeps the shop floor comfortable and, with a system that heats as well as cools, keeps it warm in winter too.

We install air conditioning for shops and retail units, from small high street shops to larger stores. For other business premises, see our guide to commercial air conditioning.

Choosing the Right System

• Wall-mounted units suit small shops, back offices and staff rooms, and they are the lowest-cost option. See wall-mounted air conditioning.

• Ceiling cassettes suit shops with a suspended ceiling. They spread air evenly across the shop floor and keep walls free for displays. See ceiling cassette air conditioning.

• Ducted systems hide everything above the ceiling, leaving only grilles. They suit boutiques and showrooms where appearance matters. See ducted air conditioning.

• Multi-split and VRF systems serve several areas, such as the shop floor, fitting rooms, a stockroom and an office, from one outdoor system. See multi-split air conditioning and VRF and VRV systems.

Getting the Details Right

• Size for the heat. Lighting, people and sun through the shop window all add to the heat, so a shop often needs more cooling than its floor area suggests.

• Keep airflow off the counter. Position units so air does not blow directly on staff at the till.

• Doors. Air conditioning works best with the door closed. A door propped open lets cooled air out and warm air in, so the system works harder.

• Fitting rooms and stockrooms. Small enclosed rooms warm up fast and may need their own unit.

• Lockable controls. Many controllers can be locked, so settings cannot be changed by customers or turned to extremes.

• Stock. Some products, such as chocolate, cosmetics and medicines, can be damaged by heat, and air conditioning helps keep them within a safe range.

Permissions for Shops

• Your lease. Under most shop leases, you need the landlord's consent for alterations, including outdoor units and holes through walls.

• Planning. Outdoor units on shop premises may need planning permission, especially on the front of a building, in a conservation area or on a listed building. Councils often ask for a noise assessment, usually based on BS 4142.

• Neighbours. Many shops have flats above them. We position outdoor units with neighbours in mind, away from their windows where possible.

Heating in Winter

Many shops rely on electric heaters. A system that heats as well as cools can replace them and uses less electricity for the same heat, because it moves heat rather than making it. Read more about air conditioning as a form of heating.

Rules and Tax Relief

Larger systems need regular F-gas leak checks, and systems over 12 kW need an energy inspection at least every five years. Air conditioning in business premises can also qualify for capital allowances. Our guide to commercial air conditioning explains these rules.

What Does It Cost?

The cost depends on the size and layout of the shop, the type and number of indoor units, the pipe route and where the outdoor unit can go. We give you a clear written quote after a free survey.

Frequently Asked Questions

Does air conditioning work with the shop door open?

It still cools, but much less efficiently, because cooled air escapes and warm air comes in. Keep the door closed where you can.

Where does the outdoor unit go?

Usually at the rear, on a flat roof or in a yard, out of sight from the street, with the pipework run through the ceiling void. See our guide to air conditioning outdoor units.

How often does shop air conditioning need servicing?

We recommend a service at least once a year, or twice a year if the system is used for heating. Busy shops may need the filters cleaning more often. See our air conditioning servicing page.
