Ask anyone in Doncaster how they slept through the last few summers and you'll get the same answer: not well. UK summers are getting hotter — the country passed 40°C for the first time on record in 2022 (just up the road in Lincolnshire), heat-health alerts now arrive most years, and our brick-built homes hold onto that heat long after the sun has gone down. Upstairs bedrooms turn into ovens, and a desk fan only moves the warm air around.
So it's no surprise that one of the fastest-growing questions we hear at Yorkshire Green Heating is no longer just about staying warm in winter — it's "can you help us stay cool in summer?" The answer is yes: professionally installed home air conditioning is coming soon to YGH. This guide explains what home cooling actually involves in 2026, the systems and what they cost, the clever modern units that cool in summer and heat in winter, what they cost to run, and the rules you need to know — and how to register your interest so you're first in line when we launch.
Why So Many Doncaster Homes Are Thinking About Air Conditioning
For decades, home air conditioning in Britain was something you saw on holiday, not at home. That's changing fast, and for good reasons:
- Hotter, longer summers. Recent UK summers have been among the warmest on record, and 30°C-plus spells that used to be rare now arrive several times a season.
- Sleep and health. A bedroom that won't drop below 25°C at night wrecks your sleep — and prolonged heat is a genuine health risk for older people, babies and anyone with a heart or breathing condition. That's why the UK now runs a formal heat-health alert system.
- Working from home. A lot more of us now spend the working day in a spare-room office that bakes by mid-afternoon.
- Our housing stock. Solid-brick and cavity-wall homes across Doncaster are built to keep heat in — brilliant in January, miserable in a July heatwave.
Air conditioning isn't a luxury the way it once was — for a lot of households it's becoming the difference between a comfortable, productive summer and a sweltering one.
The Main Types of Home Air Conditioning (and Rough 2026 Costs)
"Air conditioning" covers a few quite different things, from a cheap plug-in box to a properly installed whole-home system. Here's the honest at-a-glance picture before we dig in:
Portable unit: roughly £300–£700. Single split system (one room), fitted: roughly £1,800–£3,500. Multi-split system (several rooms), fitted: roughly £4,000–£8,000+. Final prices depend on the units, the number of rooms, the pipe runs and where the outdoor unit goes.
1. Portable units — £300 to £700
A free-standing box on castors that vents hot air out of a window through a hose. Cheap and instant, and fine as a short-term fix for one room — but they're noisy, far less efficient, take up floor space and only take the edge off a really hot room. A stop-gap, not a solution.
2. Single split system — £1,800 to £3,500 fitted
The most popular proper option. A slim wall-mounted indoor unit is paired with a small outdoor condenser, linked by thin pipework. It's quiet, efficient and genuinely cools (and dehumidifies) a single room or zone — ideal for a main bedroom, a living room or a home office. For most Doncaster homes, one well-placed split system in the room that matters most is the sweet spot.
3. Multi-split system — £4,000 to £8,000+ fitted
One outdoor unit feeds several indoor units, so you can cool multiple rooms independently — different temperatures in the bedrooms and the lounge, all from a single outdoor condenser. This is the route to whole-home comfort, and the price reflects the extra indoor units and pipework.
The Clever Part: Air Conditioning That Heats Too
Here's the bit that fits perfectly with what we do as a green heating firm. A modern split-system air conditioner is really an air-to-air heat pump — and it runs in reverse. In summer it moves heat out of your home (cooling); in winter it moves heat in (heating), and it does so very efficiently, typically delivering around three units of heat for every unit of electricity it uses.
That means one system gives you year-round comfort: cool bedrooms in August and fast, efficient top-up heat in the shoulder months. It's not usually a full replacement for a wet central-heating system feeding your radiators — for that, see our central heating page — but as a comfort system it's superb, and the winter heating mode means the unit earns its keep all year rather than sitting idle for nine months. For homeowners already thinking about efficiency and smart control, it pairs naturally with the kind of kit we cover in our smart thermostats guide.
What Does Air Conditioning Cost to Run?
Running cost comes down to three things: the size of the unit, its efficiency rating (look for a high SEER for cooling and SCOP for heating, and an A+++ energy label), and how much you actually use it. The good news is that a modern, correctly-sized split system is far more efficient than an old portable or a panel heater.
As a realistic guide, cooling a bedroom for a few hours on a hot evening costs pennies to low tens of pence an hour on a modern A-rated unit — you don't run it 24/7, you use it to take a room from unbearable to comfortable. In heating mode, because a heat pump multiplies the energy it uses, the cost per unit of heat can undercut direct electric heating and stay competitive in milder weather. We'll always size a system to the room and give you honest running-cost expectations rather than a sales-brochure number.
The Rules: F-Gas, Planning and Building Regs
Air conditioning isn't a DIY job, and it's worth knowing why before you buy a unit online:
- F-Gas certification. AC systems contain refrigerant gases, and by law the company installing them must be F-Gas certified to handle those refrigerants. An uncertified or DIY install isn't just risky — it's illegal, and it voids manufacturer warranties. Always use a certified installer.
- Planning permission. Most domestic air conditioning is fine under permitted development, but the outdoor unit has conditions — its size, where it sits, noise, and whether you're in a conservation area or a flat or listed building. It's a quick thing to check before anyone drills a hole in your wall.
- Building regulations. A proper install means a safe electrical supply, correct condensate drainage and a tidy, weatherproof outdoor unit — all done to standard.
This is exactly the sort of thing a qualified, local firm handles as a matter of course — which brings us to the announcement.
Coming Soon to Yorkshire Green Heating

We're finalising the details now and plan to launch later in 2026. There's a real logic to heating and cooling coming from the same trusted local team: one firm that understands your home's comfort all year round, clear itemised pricing, qualified engineers and work that's actually rated by your neighbours. If you'd like cooling sorted before next summer's first heatwave, the sensible time to plan is now — not in the middle of a 32°C week when everyone's calling at once.
