From Heat Pumps To Air Conditioning: How Is Climate Change Shifting Markets In The UK And EU?

For years, Europe’s climate strategy has largely been built around a primary assumption – winters matter most.

Governments pushed heat pumps, homeowners invested in insulation and policymakers focused on reducing reliance on gas heating. The goal, across the board, was to make buildings warmer, more efficient and less dependent on fossil fuels.

But now, after yet another “unexpected” summer of record-breaking temperatures, that conversation is beginning to change. Because the thing is, at some point, we need to accept that these shocking and surprising heat waves are no longer that shocking – it’s becoming the new normal.

Western Europe has just experienced its hottest June on record, and the UK is currently enduring its third heatwave of 2026. Scientists say these events are becoming more frequent and more intense as the climate warms.

As a result, the real question for businesses, investors and consumers is becoming not how to keep warm in the winter, but rather how to keep cool in the summer?

The Cooling Economy Is Arriving

Historically, spending on buildings across the UK and much of northern Europe has been centred on heating.

From double glazing and cavity wall insulation to smart thermostats and heat pumps, the focus has been on retaining warmth during long winters. Even the heat pump market itself has faced growing scrutiny around costs, installation challenges and suitability for certain properties as adoption has expanded.

But, recent heatwaves have exposed another issue. That is, many European buildings were designed to trap heat rather than release it.

And we’re starting to really feel and see the consequences. More than 1,000 schools across the UK were forced to close or partially close during recent periods of extreme heat, while hospitals, supermarkets and public services have all reported disruption linked to rising temperatures.

In other words, Europe’s building stock may be becoming increasingly efficient for the climate it used to have, rather than the one it is heading towards.

Is Air Conditioning Europe’s Next Major Growth Market?

According to Euro News, the numbers suggest that there’s significant room for growth. While air conditioning is considered standard in much of the United States, adoption across Europe remains relatively low. Around 20% of European households have air conditioning compared with more than 90% in the US, Japan and South Korea.

That gap represents a potentially enormous commercial opportunity.

As temperatures climb, demand is increasing not only for traditional air conditioning units but also for portable cooling systems, ventilation upgrades, smart building technologies and commercial cooling solutions.

For installers, manufacturers and HVAC providers, the market outlook is becoming increasingly attractive. For startups, however, the opportunity may be even broader.

Climate Adaptation Is Becoming A Business Category

For years, climate-tech investment has largely focused on reducing emissions, but now, a growing number of companies are focused on helping people adapt to climate change instead.

This shift is creating opportunities across multiple sectors. Businesses are developing smarter cooling systems that use less electricity, software platforms that optimise building temperatures, advanced shading technologies and new materials designed to keep buildings cooler without increasing energy consumption.

So, the challenge here is obvious. If millions of European households suddenly install air conditioning, electricity demand could surge during heatwaves, creating new pressures on energy infrastructure. Researchers have already warned that rapid increases in air-conditioning adoption could significantly increase peak electricity demand across countries such as Germany.

That means the winners may not simply be companies selling cooling systems, but those finding ways to make cooling more efficient.

Property Markets Could Feel the Impact Too

Climate change is also starting to influence how people think about property. Traditionally, homebuyers in the UK paid attention to factors like insulation ratings, boiler efficiency and heating costs. And now, resilience during heatwaves is entering the conversation, too.

Can a property remain comfortable during several consecutive days above 30°C? Does it have adequate ventilation? Are there external shading systems? Could cooling technology be installed easily?

Developers are already facing growing pressure to design buildings that can cope with both colder winters and hotter summers.

In many ways, Europe’s housing market is beginning to adapt to climate realities that have long shaped property development in warmer parts of the world.

The Next Decade May Look Different – And It Probably Should

The shift from heating to cooling doesn’t mean heat pumps are disappearing. Rather, heating will remain a critical part of Europe’s energy transition, but the difference here now is that climate change is broadening the conversation.

The market isn’t just solely focused on staying warm. Now, it’s becoming more about maintaining comfortable, safe indoor environments all year round.

As heatwaves become more common, entirely new markets are emerging around cooling infrastructure, building resilience and climate adaptation. What was once considered a niche concern is very quickly becoming a mainstream business opportunity.

So, while much of the tech world remains focused on AI, some of the most significant growth opportunities of the coming decade may come from a far more physical challenge – helping people cope with a hotter world.

And for businesses paying attention to these market changes, the opportunities are already here.
