Less than 5% of homes in the UK are equipped with air conditioning, a stark contrast to the US, where it’s a standard feature in most homes. While AC is often seen as a luxury in the UK, the reality of climate change is starting to shift attitudes, and the demand for air conditioning is set to rise dramatically.
As summers grow hotter and heatwaves become more frequent, it’s easy to see why more people across the UK will soon wish they had air conditioning. With climate projections showing more intense and prolonged heat, the cooling solutions that were once considered unnecessary may become essential for health, comfort, and productivity.

By the end of this post, you’ll understand why more UK homeowners will wish they had air conditioning in the coming years, and how you can start planning to future-proof your home against the increasingly hot weather.
Why Air Conditioning is Rare in the UK (For Now)
While AC may seem like a foreign concept to many UK homeowners, the reasons for its rarity aren’t hard to understand:
- Mild Climate: Historically, the UK has had relatively cool summers, with heatwaves being rare. This made the need for air conditioning unnecessary, and so, it wasn’t a priority for most homeowners.
- Housing Stock: Much of the UK’s housing stock consists of older, terraced homes and period properties, which are designed to trap heat. Installing air conditioning in these homes can be challenging and costly, particularly when retrofitting or working around strict planning regulations.
- Cultural Perception: For many, air conditioning is still seen as a luxury item associated with hot countries. Historically, Brits have preferred natural ventilation and fans as their primary means of cooling.
- High Costs: AC installation can be expensive, especially in older homes or in buildings with limited infrastructure to support it. Additionally, running costs, given the UK’s rising electricity prices, can deter homeowners from adopting AC as a cooling solution.
But with the climate changing, this outlook is rapidly shifting.
How Climate Change Is Changing the Need for Air Conditioning
The most striking change is the increase in heatwaves and rising summer temperatures. Over the last few decades, the UK has experienced an increase in the frequency and intensity of heatwaves, with temperatures regularly exceeding 30°C in recent summers. By 2050, some climate models predict that the UK could experience up to 10 times more heatwaves than we do today.
- Rising Temperatures: The UK is getting hotter. According to Dr Gillian Kay, Senior Scientist at the Met Office, “the chance of exceeding 40°C has been rapidly increasing, and it is now over 20 times more likely than it was in the 1960s.” This means hotter summers will become the norm, and people will be more dependent on air conditioning to stay cool.
- Increased Health Risks: Higher temperatures lead to more extreme weather events, like heat stress, dehydration, and even heatstroke. Vulnerable groups (the elderly, young children, those with underlying health conditions) are particularly at risk, and AC offers a potential life-saving solution.
- Overheating Homes: Studies show that 20% of homes in England already suffer from overheating during an average summer. In cities like London, this figure can be much higher, where urban heat islands exacerbate the issue. If the UK continues to warm, more homes will be prone to overheating, and people will increasingly wish for better cooling options.
Why Do People in the UK Wish They Had Air Conditioning?
Air conditioning may not be needed year-round in the UK, but it is quickly becoming essential during increasingly frequent heatwaves. One of the most noticeable times people will regret not having AC is during long, hot summers. With climate change driving up the frequency and intensity of heatwaves, the average British summer is becoming hotter and longer. When high temperatures persist for weeks or even months, relying on fans and other passive cooling methods will no longer suffice.
Another key concern is the tendency of modern homes to overheat. Contemporary designs featuring large glass windows and open-plan layouts often trap heat, making interiors uncomfortably warm. Without air conditioning, these homes can quickly become unbearable and, in some cases, hazardous to health.
For vulnerable populations, such as the elderly, young children, and individuals with certain medical conditions, the absence of air conditioning can be especially dangerous. In extreme heat, discomfort can escalate to serious health risks, making cooling systems not just a convenience but a necessity.
Is Air Conditioning the Solution?
While installing air conditioning might not have been seen as essential in the past, future climate scenarios make it an increasingly viable solution to beat the heat. Here’s how things will look in the coming years:
- Installation Challenges: It’s true that installing AC in older homes can be tricky, especially with the lack of ductwork and insulation. However, new split systems and portable units offer an easier, more cost-effective solution for many homeowners. In fact, many UK homes could benefit from these modern, energy-efficient AC units.
- Policy Change: As the climate shifts, the government may introduce new policies to help homeowners transition to more climate-adapted homes. Tax incentives or grants for installing air conditioning systems, especially in areas most affected by heat, could become a reality.
- Modern Solutions for Traditional Homes: Split units, portable ACs, and energy-efficient ductless systems are now available, making AC more accessible to UK homeowners, even in older properties where traditional systems may not be viable.
The Pros and Cons of Air Conditioning
While AC offers significant benefits, especially as the UK’s climate warms, it’s not without its drawbacks.
| Pros | Cons |
| Provides effective cooling during heat waves, and heating in the winter | Installation can be complex in older homes |
| Improves comfort, productivity, and health | Running costs, especially during peak summer |
| Essential for vulnerable populations | |
| Can help manage indoor temperatures in modern homes | |
| Most systems have little to no emissions and are A+++ energy rated to run |
How Expensive Would It Be for All UK Homes to Have AC?
Installing AC in 28 million homes in the UK would cost upwards of £42 billion (at £1,500 per home for a basic split system), excluding running costs and upgrades for older homes. This massive financial burden, along with the increase in national energy consumption, underscores the importance of thinking ahead; the longer the delay in adopting AC, the higher the costs will be in the future.
Will Air Conditioning Be Expensive to Run in the Summer?
Running air conditioning can get costly, especially with rising energy prices in the UK. But as the number of heatwaves increases, more homeowners will face higher monthly energy bills in the summer.
However, there are ways to reduce these costs, such as using energy-efficient models and switching to off-peak energy tariffs; there are even Government grants to help with the cost of installation.
Passive Cooling and Policy Considerations
While AC is one solution, passive cooling strategies should still be prioritised. Experts recommend improving insulation, using natural ventilation, and introducing green roofs or cool pavements in urban areas. These strategies can reduce the need for AC in many homes, while still offering relief from heat.
As the UK’s climate changes, government initiatives should further focus on building climate-adapted homes, introducing sustainable cooling solutions, and offering incentives for energy-efficient air conditioning systems.
