The United Kingdom is facing a growing debate over the use of air conditioning as extreme heat events become more frequent. This discussion highlights a societal divide between those who view the nation's historical aversion to cooling as a form of masochism and those who advocate for greater adoption of the technology.
David Lawrence of the Centre for British Progress think tank argues that the reluctance to install air conditioning is inconsistent, noting that while homes are heated in winter, cooling is often dismissed in summer. He points out that air conditioning is common in commercial settings like offices, hotels, and shops, but not typically in schools and hospitals, despite the significant impact of heat on concentration, learning, and health in these environments.
This dispute has entered the political arena. Some local councils in London are promoting low-energy cooling methods and, in some instances, have instructed property owners to remove air conditioning units. This approach has been criticized by some Conservative politicians as "dark ages" thinking, while others are calling for an "air-con revolution."
The UK government has introduced measures that could indirectly support cooling. Since April, the Boiler Upgrade Scheme in England and Wales has offered a £2,500 grant for reversible air-air heat pumps, which can provide both heating and cooling. However, this subsidy is presented as a heat pump grant and is significantly less than the £7,500 available for heating-only models. In its first month, only around 45 households claimed the grant for reversible heat pumps, compared to thousands for heating-only models.
Similar support structures vary across the UK. Scotland offers a £7,500 grant for heat pumps through its Home Energy scheme, but specifically excludes funding for air-air versions capable of cooling. Northern Ireland does not offer a universal heat pump grant for households. Furthermore, the scheme in England and Wales is not accessible to social housing residents or those in new builds, categories of people who are often most vulnerable to heat.
Examples of the challenges faced by residents include a tenant in a top-floor flat in Woolwich, London, whose home reportedly reaches 43C during heatwaves. This resident and approximately twenty neighbors are pursuing legal action against their landlord, PA Housing, citing uninhabitable living conditions. The debate over air conditioning in the UK intersects with broader discussions about climate change adaptation and mitigation strategies. Questions remain about the cost-effectiveness and environmental consequences of widespread air conditioning adoption versus investing in other methods to combat rising global temperatures. Charts indicate that UK heatwaves are projected to become hotter, underscoring the urgency of addressing heat impacts on health and the economy.
