London faces surge in wildfires and flooding amid climate crisis escalation

London’s emergency services are confronting unprecedented wildfires and flooding, with costs surpassing £11 million annually, highlighting urgent demands for climate resilience and urban sustainability measures.

Since 2018, London’s emergency services have faced escalating challenges responding to the twin threats of wildfires and flooding, with expenditures exceeding £11 million on these climate-driven incidents alone. The London Fire Brigade (LFB) has tackled 808 wildfires over the past seven years, costing more than £5.4 million to combat. In 2025, wildfire incidents have remained alarmingly high, with 121 occurrences requiring deployment of over 4,000 personnel and costing around £766,000. Concurrently, the city has spent an estimated £5.86 million dealing with flood-related emergencies since 2018, including £558,000 for 195 incidents in 2025 alone.

The surge in these extreme events has been underscored by the Mayor of London, Sir Sadiq Khan, who described climate change as having a “devastating impact” on the capital’s environment, pushing once remote dangers like wildfires onto London’s doorstep. Labour Assembly Member Leonie Cooper, who obtained the cost figures through written questions to City Hall, stressed that these are not hypothetical threats but realities manifesting annually. She highlighted the urgent need for sustained investment in climate resilience measures—from greener urban spaces and cooler housing to sustainable drainage systems—to alleviate the growing strain on both the public and emergency responders.

This summer, London endured four separate heatwaves, making 2025 the warmest season on record for the UK, according to Met Office data. The extended dry periods left the city’s green spaces parched, heightening wildfire risks, all of which have been largely attributed to human negligence—disposable barbecues, discarded cigarettes, and other ignition sources near dry grassland being the most common culprits. The borough of Havering has been particularly hard-hit, registering the highest number of wildfires at 158 since 2018, including the devastating 2022 Wennington blaze that destroyed over a dozen homes. Other vulnerable boroughs include Hounslow, Enfield, Bromley, and Hillingdon, all facing dozens of incidents in recent years.

The London Fire Brigade reported its busiest summer since the 2022 wildfires, attending 83 cases in June, July, and August 2025 alone, bringing the year’s total to 117 wildfires, more than double the number from 2023 and a significant increase on 2024. Despite this surge, the total remains below the record 207 fires in 2022, when heatwaves peaked at a scorching 40 degrees Celsius. To respond more effectively, the Brigade has trialled innovative off-road 4×4 wildfire response vehicles that can access challenging terrains unreachable by standard fire engines. These vehicles played a critical role during major incidents, such as the Dagenham wildfire in July 2025, where pre-planned fire breaks, in coordination with local councils, prevented the blaze from reaching residential homes.

The operational experience underscores a clear pattern: as climate change intensifies, so too does the frequency and severity of these natural hazards. The London Climate Resilience Review, published in mid-2024, pointed to the increasing intensity of wildfires and flooding as consequences of shifting weather patterns. The report also called for integrated land management policies that better align urban planning with natural environments to mitigate wildfire risks, and it flagged flooding as a significant economic threat—recent data from Zurich UK suggests that 42% of London’s commercial buildings are vulnerable to torrential rain flooding, with average losses considerable for both homes and businesses.

Flooding remains a formidable challenge in the capital. The Greater London Authority has identified flash flooding as the principal environmental risk to residents, with analysis indicating that nearly half of London’s hospitals and a fifth of its schools could be affected. More than half a million homes and businesses are at medium to high risk of flooding. Sir Sadiq Khan has warned specifically that over 50,000 basement properties face increased flood risks due to climate change-induced weather shifts. Over the past decade, the London Fire Brigade has seen an upward trend in flood-related emergencies, responding to over 8,250 incidents annually on average in recent years, with a near 31% increase in flood call-outs noted before 2024.

Assistant Commissioner Pat Goulbourne from the LFB emphasised the collective responsibility required to mitigate wildfire risks, urging both public caution and proactive landowner management such as creating fire breaks to limit damage. The Brigade has invested significantly in new equipment and training, learning from past summers, especially the intense 2022 heatwave, to remain prepared for future challenges. Continued funding, technological adaptation, and community cooperation remain crucial, she noted.

The Mayor’s office reiterated the urgency of these climate threats, highlighting ongoing collaboration with the London Fire Brigade, local councils, and partners to enhance resilience and reduce carbon emissions. The aim is to shield Londoners from escalating environmental hazards that threaten lives, homes, and infrastructure while promoting a sustainable, safer urban future.

Overall, the rising costs associated with wildfire and flood management in London reflect a broader national pattern observed by the National Fire Chiefs Council, which reported dramatic year-on-year increases in wildfires and flooding incidents across England and Wales, tied to climate change. These findings sound a clear call for better preparation and investment to safeguard communities and emergency services alike against the growing menace of extreme weather.
