Shop and salon cooling: the winter heating benefit

If you run a small shop or a salon, you probably think about air conditioning in July and pay the electric heater bill in November. Modern commercial units heat as well as cool. The winter heating saving is often bigger than the summer cooling benefit.

The honest maths

A typical UK high street salon or independent shop, 60 to 100 square metres, open six days a week:

• Winter electric heating with wall heaters or fan heaters: £180 to £280 a month at 2025 electricity prices.
• Same space heated with a commercial split system on heat mode: £70 to £110 a month for equivalent warmth.

That is £600 to £1,000 saved across the four coldest months. Every year.

Add in the summer cooling benefit - staff productivity does not fall off a cliff at 28 degrees, customers browse for longer, tinted stock does not need to be culled - and the payback on the install lands inside two to three years for most small commercial jobs.

Why the numbers look this way

Small commercial spaces are usually heated with the cheapest kit available: electric fan heaters, oil-filled radiators, or an old gas warmer at the back. All of them are basic resistance heating. 1 kW in, 1 kW of heat out.

A commercial split system on heat mode has a coefficient of performance of 3.0 to 3.8 - meaning 1 kW of electricity in, 3 to 3.8 kW of heat out. Three times the warmth for the same electricity bill.

The exact ratio depends on outside temperature, but for the average UK trading day between October and March, the gap holds.

What you get for £4,000 to £6,000

A fitted single-cassette install in a 60 to 100 square metre small commercial space is £3,500 to £6,000 depending on brand, ceiling type, and outdoor unit access.

That price includes:

• The commercial-grade indoor cassette and outdoor unit.
• A qualified electrical hookup with an isolator switch.
• Refrigerant charge and commissioning under F-Gas.
• Manufacturer warranty registration - usually 5 years on commercial kit.
• Documentation for your insurance and lease renewal.

Not included: an annual F-Gas service, which is £180 to £280 per year for a single-unit setup.

The three shops we get the most enquiries from

Hair and beauty salons. Chemical heat from dryers plus a full waiting area of clients equals a hot room by 2pm. Air con removes the humidity as well as the heat - which is why the clients stay longer.

Independent retail. High street shops with large front windows. Solar gain is severe from March to September and the space is expensive to heat in winter. Cassette systems handle both extremes.

Cafes and small food service. Kitchen heat plus warm coffee equipment plus front-of-house temperature control. Multi-split systems zone the front and back separately so the servers do not roast while customers stay cool.

What to check on a commercial quote

Three things that separate a good commercial quote from a domestic one dressed up:

1. Duty cycle. The installer should ask about your trading hours. A system that only runs 4 hours a day gets specified differently to one running 12.
2. Landlord permission. If you are in a rented commercial unit, you need written landlord sign-off for the outdoor condenser. The installer should ask, not assume.
3. Service contract. Ask for an annual service quote at the same time as the install. Do not sign one for five years - a one-year rolling contract is standard.
