Midlands-based heating and plumbing company, Custom Heat, has said it has seen sales of air conditioners soar because of the unprecedented heatwave conditions that has gripped the UK in the past few weeks. The company reports that June 2025 was the biggest month for air conditioning sales in its history, with demand continuing to surge through July (sales are already up 55% compared to the same period last year).
“We’ve never experienced anything like this level of interest in air conditioning systems,” says MD Lincoln Smith. “The demand has been absolutely extraordinary. We’re working around the clock to ensure we can satisfy customer requirements.”
The surge comes as the UK faced its third heatwave of 2025, following the warmest and sunniest spring on record. England experienced its warmest June since records began in 1884, with temperatures reaching 35.8°C in Kent on 1 July.
Lincoln explains that the company has had to scale up operations significantly to meet demand, as the widespread nature of the heatwave drove unprecedented sales across all regions. “We’re seeing interest from customers who previously considered air conditioning unnecessary in the UK climate,” he adds. “People are recognising that extreme weather events like this are becoming more frequent, and they’re investing in solutions that will keep their homes comfortable.”
While summer cooling drives immediate sales, Custom Heat continues to promote the year-round benefits of modern air conditioning systems. “These systems provide excellent air filtration, which is particularly beneficial for hay fever sufferers during pollen season,” says Lincoln. “They also offer efficient heating capabilities during winter months, making them a complete climate solution.”
Industry research has previously identified the UK’s relatively low levels of domestic air conditioning use compared to other countries, suggesting significant scope for market growth as temperatures rise due to climate change.
