The UK Heat Tax: When the Weather Stops Being Small Talk
Brits have always loved talking about the weather. Living in a country where sunshine, showers and four seasons can all arrive in the same afternoon means it's long been part of our national identity. We celebrate the sunny days, complain when it gets too hot or too wet, and usually get on with it.
Our latest research suggests this summer feels different. Heatwaves are no longer being treated as a short-lived inconvenience. They are becoming something we need to live with, and with that comes a growing realisation that coping with them isn't as simple as opening a window or buying another fan.
The biggest shift is the level of adaptation now required and, more importantly, who is expected to pay for it. Increasingly, households are absorbing the cost of hotter summers through higher energy bills, cooling products and disrupted routines. It's a burden many people feel has by default landed with them, despite believing responsibility should sit more broadly with government, public services and businesses. It's what we might reasonably call the UK's Heat Tax: the growing cost of adapting to hotter summers.
Heatwave disruption is becoming part of everyday life
Heatwaves are no longer viewed as exceptional events. 66% of people say they're concerned about more frequent heatwaves, and the same proportion (67%) say they now think about preparing for them more than they used to. Hotter summers have become something people increasingly expect rather than something that catches them by surprise.
The challenge is that our homes, communities and routines haven't adapted at the same pace. Just 35% believe their home is well equipped to stay cool during a heatwave, down sharply from 50% when we asked the same question during last year's summer heatwave. Meanwhile, 93% say recent heatwaves have affected their lives in some way, with 80% experiencing disruption to their daily routine and 38% describing that disruption as significant.
That disruption extends well beyond discomfort. Nearly two thirds (65%) struggle to sleep during heatwaves, 62% find it difficult to keep themselves cool and 61% struggle to keep their homes comfortable. 18% say their mental health has been affected, rising to 28% among 25–34-year-olds.
The cost of coping is increasing
As temperatures rise, so too does household spending. 57% have already bought products to help them stay cool this summer, while a further 10% still expect to make purchases before the summer ends. Fans remain the most common purchase (57%), followed by cooler clothing (25%), blackout blinds or curtains (19%) and air conditioning units (17% portable, 7% built-in).
For many households, however, the changes they would like to make remain out of reach. 52% say they can't afford the improvements that would help keep their homes cooler. 64% say the cost of living makes preparing for hotter summers more difficult, while 73% would use cooling appliances more if energy costs were lower. 60% say they would install air conditioning if the upfront cost were more affordable.
The result is that resilience to extreme heat risks becoming another marker of inequality. Those with the means to invest in cooling their homes can better protect themselves from disruption, while others are left managing poorer sleep, higher energy bills and homes that become increasingly difficult to keep comfortable.
Consumers don't think they should shoulder the burden alone
What makes these findings particularly interesting is the gap between what people are doing and what they believe should happen. Consumers are adapting because they feel they have little choice, not because they believe it's their responsibility. Only 13% think consumers and households should take primary responsibility for helping the UK adapt to hotter summers. Instead, most believe responsibility sits with national government (57%), followed by local councils (33%) and utility companies (32%).
That expectation reflects wider concerns about how prepared the country really is. 58% believe schools are not well prepared for more frequent heatwaves. 53% say the same about water supply and drought management, while around half (49%) question whether workplaces provide safe environments during periods of extreme heat. Confidence is similarly low across hospitals, transport infrastructure and local services.
Consumers are adapting, but simply don't feel the systems around them are keeping pace.
People aren't rejecting investment, but they do need certainty
Given the breadth of the impact, it was interesting that only 19% of respondents support paying higher household bills or taxes to prepare the UK for hotter summers. That might suggest little appetite for public investment. However, a closer look at the data shows that consumers aren't rejecting investment outright, but they are rejecting the idea that the Heat Tax should continue to fall disproportionately on households without tangible improvement in their own circumstances.
When people can see exactly what their money would achieve, support increases dramatically. 81% would support paying more if funding was ringfenced specifically to help hospitals and care homes cope with extreme heat, make homes easier to keep cool, protect vulnerable communities or improve water resilience. There's strong conditional support for clear and targeted spending.
A practical opportunity for brands to help alleviate the Heat Tax
75% believe brands should do more to help people stay cool affordably. Anything that makes it easier or more affordable for people to adapt will be valued.
Whether that's reducing the cost of cooling products, designing more energy-efficient solutions, helping households reduce running costs or providing practical advice that genuinely helps people cope, brands have an opportunity to ease a burden that consumers increasingly feel they're carrying alone. In doing so, they can build positive sentiment by demonstrating that they understand the realities consumers are facing.
The economic cost of doing nothing is tangible
If it's left unaddressed, the Heat Tax won't remain a household issue. It will increasingly become an economic challenge. Every disrupted night's sleep, overheated workplace, school affected by extreme heat, and household forced to spend more on staying cool carries a cost. Collectively, those costs begin to affect productivity, place additional pressure on public services and leave households with less to spend elsewhere. At a time when economic growth is high on the UK's agenda, the impact won't just be evident in household budgets. It will increasingly be felt in the country's ability to grow.
