There were 667,479 deaths in the United Kingdom in 2021, compared with 689,629 in 2020. Between 2003 and 2011, the annual number of deaths in the UK fell from 612,085 to just over 552,232. Since 2011 however, the annual number of annual deaths in the United Kingdom has steadily grown, with the number recorded in 2020, the highest since 1918 when there were 715,246 deaths. Both of these spikes in the number of deaths can be attributed to infectious disease pandemics. The great influenza pandemic of 1918, which was at its height towards the end of World War One, and the COVID-19 pandemic, which caused a large number of deaths in 2020.  Impact of the COVID-19 pandemic The weekly death figures for England and Wales highlight the tragic toll of the COVID-19 pandemic. In two weeks in April of 2020, there were 22,351 and 21,997 deaths respectively, almost 12,000 excess deaths in each of those weeks. Although hospitals were the most common location of these deaths, a significant number of these deaths also took place in care homes, with 7,911 deaths taking place in care homes for the week ending April 24, 2020, far higher than usual. By the summer of 2020, the number of deaths in England and Wales reached more usual levels, before a second wave of excess deaths hit the country in early 2021. Although subsequent waves of COVID-19 cases resulted in far fewer deaths, the number of excess deaths remained elevated throughout 2022. Long-term life expectancy trends As of 2022 the life expectancy for men in the United Kingdom was 78.57, and almost 82.57 for women, compared with life expectancies of 75 for men and 80 for women in 2002. In historical terms, this is a major improvement in relation to the mid 18th century, when the overall life expectancy was just under 39 years. Between 2011 and 2017, improvements in life expectancy in the UK did start to decline, and have gone into reverse since 2018/20. Between 2020 and 2022 for example, life expectancy for men in the UK has fallen by over 37 weeks, and by almost 23 weeks for women, when compared with the previous year.

There were 309 fire-related fatalities in Great Britain in the 2023/24 reporting year, a decline on the previous reporting year when there were 323. In the early 2000s, the annual number of fire fatalities was consistently over 500, with numbers gradually falling throughout that decade. In 2011/12 the number of fatalities related to fire fell below 400 for the first time, and has remained below 400 since that point. Incidents rise as workforce shrinks Although there has been a net decrease in the number of incidents attended by fire and rescue services since the early 2010s, the current trend from 2014/15 onwards has been one of increase. In 2022/23, there were 759,456 incidents attended by the fire service, which was the most in a reporting year since 2010/11. Like many other public services, the fire service cut significant numbers of staff during the 2010s, with the number of fire and rescue workers in England falling by around 10,000 between 2008 and 2018. In a similar time period, expenditure on fire-protection services in the UK was cut from 3.11 billion in 2009/10, to just 2.72 billion in 2018/19. Workplace fatalities also declining The fall in fire-related fatalities since the 1980s is evidence that the UK has become an increasingly safe society in recent decades. The significant fall in workplace deaths is also evidence of this, with fatal injuries at work declining from 651 in 1974 to just 135 by 2023. Injuries to workers have also fallen, with incidents almost halving between 2000/01 and 2022/23. The large shift from more dangerous jobs in manufacturing, production, and agriculture to service-orientated roles also certainly play a role in this decline as well.

The dataset consists of air temperatures recorded longitudinally and reported at hourly intervals using Hobo MX1101, Hobo MX1102A and Hobo MX2301 devices. The monitoring period covered 1st May 2022 to 30th September 2022 inclusive – the full non-heating season in England.

The devices were deployed in 30 care homes across England: eleven in Greater London, nine in the north of England as far north as Newcastle-upon-Tyne, six in the Midlands, and four in the south of England including on the Isle of Wight. The locations monitored consisted of 22 offices (staff-only areas such as manager’s offices, administrator offices, nurse stations), 30 lounges (communal areas such as lounges, dining rooms and lounge/diners), and 30 bedrooms (single rooms, with a range of occupancy – some vacant, some occupied only at night, others occupied 24/7 depending on resident needs). In addition, outdoor temperatures were monitored at each of the 30 care homes.

As a result of global climate change, the UK is expected to experience hotter and drier summers, and heatwaves are expected to occur with greater frequency, intensity and duration. In 2003 and 2018, 2,091 and 863 heat-related deaths, respectively, were reported in England alone as a result of heatwaves, meaning future temperature increases could lead to a parallel rise in heat-related mortality. The UK also currently has a rapidly ageing population, with people aged 75 or over expected to account for 13% of the total population by 2035. Older populations are more vulnerable to climate-induced effects as they are more likely to have underlying, chronic health complications, making them more vulnerable to heat stress. The indoor environment is a principle moderator of heat exposure in older populations, who tend to spend the majority of their time indoors. Poor building design, the lack of effective heat management and diverging needs and preferences between staff and residents in care settings may contribute to increased indoor heat exposure with detrimental health impacts falling on the most vulnerable residents. Maladaptation to a warming climate, such as the uptake of air conditioning, could increase fuel bills in care homes, increase operational costs for businesses in the already financially stretched care sector, and increase building carbon emissions, thus undermining government efforts to reduce greenhouse gas emissions.

The one-year pilot project 'Climate Resilience of Care Settings' and previous small-scale studies led by our research team have shown that UK care homes are already overheating even under non-extreme summers. A key target for climate adaptation in care settings is to limit such risks by introducing passive cooling strategies via building design. However, preliminary modelling as part of the pilot project also demonstrated that common passive cooling strategies may not adequately mitigate overheating risk in the 2050s and 2080s. Further research into advanced passive cooling strategies, combined with human behaviour and organisational change is required to identify optimum climate adaptation pathways for UK's care provision.

The main aim of the project is to quantify climate related heat risks in care settings nationwide and enhance understanding of human behaviour, organisational capacity and governance to enable the UK's care provision to develop equitable adaptation pathways to rising heat stress under climate change. Building on the foundations of the pilot project, this novel, interdisciplinary project will collect, for the first time in the UK, longitudinal temperature and humidity data in a panel of 50 care settings in order to quantify the recurring risk of summertime overheating. We will also identify and assess social, institutional and cultural barriers and opportunities underpinning the governance of adaptation to a warmer climate in care and extra-care homes through surveys with residents, frontline care staff, managers and policy stakeholders. Within sub-samples of this panel, we will use innovative measurement techniques to collect residents' physiological data and study their relation with heat exposure and health impacts. Also for the first time in the UK, we will create a building stock model of the UK's care provision able to predict future overheating risks in care settings under a range of future climate change scenarios. This will help evaluate the effectiveness of near, medium and long term future overheating mitigation strategies and policies on thermal comfort and health outcomes. Throughout the project, we will continue to develop and expand the stakeholder community that was created during the pilot project. Through ongoing dialogue with our diverse network of stakeholders, we will explore organisational capacity and structures, and how these influence action and policy, in order to generate best practice guidance for practitioners, businesses and policymakers.
