Summer '26 will be the coldest of our lifetimes?
UK meteorologists have said 2026's summer will be the coldest of our lifetimes — meaning 2027 and beyond will be even hotter than the uncomfortable temperatures we've experienced this year. Don't wait for next year's heatwave to secure your air conditioning.
Jan–Aug: 2026 observed highs · Sep–Dec: 2027 forecast (projected hotter than 2026) · Met Office monthly maxima. Hottest: Jul (40.3°C).
Your air conditioner heats too.
Modern inverter split systems run in reverse to warm your home — moving heat in rather than burning energy to make it. That's up to three times more efficient than a standard electric heater, from the same unit that keeps you cool all summer.
Lower winter bills
Heat-pump heating delivers roughly 3 kW of warmth for every 1 kW of electricity — a fraction of the running cost of fan or plug-in heaters.
One unit, two seasons
Cooling in summer, efficient heating in winter. A single inverter split system replaces both a fan and a space heater.
Even, steady warmth
Inverters hold a set temperature without switching on and off, so rooms stay comfortably warm instead of swinging hot and cold.
Look for inverter heat-pump split systems — they heat as efficiently as they cool, all winter long.
