Heatwave and wildfires expose gaps in London’s protection for people sleeping rough

Grass fires on Wanstead Flats and amber heat‑health alerts have stretched emergency services and charities warn that people sleeping rough face heightened risk of dehydration, heat exhaustion and heatstroke — charities urge boosted outreach, cooling hubs and simple public actions that can save lives.

A series of grass fires ripped across Wanstead Flats this week as London baked in a heatwave that pushed temperatures towards the mid‑30s Celsius and prompted an amber heat‑health alert, forcing firefighters into prolonged action and prompting warnings from the London Ambulance Service about pressures on emergency responders. According to the Evening Standard’s reporting, the scale of the blazes and the wider heat have also begun to strain transport and public‑service capacity across the capital.

Speaking to the Evening Standard, James Lally, director of pan and central London and street homeless services at the charity St Mungo’s, warned that people sleeping rough are acutely exposed during such spells. “On the streets, it can be difficult to access water, sunscreen, and places to shelter from the sun, meaning that those experiencing homelessness have a particularly high risk of developing life‑threatening heat‑related illnesses such as heat exhaustion, dehydration, or heat stroke,” he said. St Mungo’s said it has boosted outreach shifts and urged members of the public to offer water or suncream to people they find sleeping rough.

Public‑health guidance reinforces those concerns. Government advice from the UK Health Security Agency explains that people sleeping rough are at heightened risk because of prolonged outdoor exposure, underlying health conditions, medication side‑effects and social exclusion that reduce the ability to take protective actions. The guidance lists direct harms such as dehydration, heat cramps, heat exhaustion and potentially fatal heatstroke, and also warns that hot weather can exacerbate chronic heart, lung and kidney disease. The NHS sets out the symptoms to watch for and simple first‑aid steps — moving someone to a cool place, giving cool drinks, cooling the skin with wet cloths — while emphasising that heatstroke is a medical emergency requiring urgent help.

Frontline charities and sector guidance set out practical measures that can reduce harm. Homeless Link’s case studies and guidance describe how outreach teams and local partnerships typically respond: distributing water, sports drinks, suncream and hats; producing maps of cool spaces and water refills; and using libraries, day centres or temporary cooling hubs as relief points. They also underline the importance of staff training to spot heat‑related illness and the logistics needed — refrigeration for cold drinks, transport and coordinated multi‑agency planning — so that support can be scaled up quickly when alerts are issued.

Charities working with young and rough‑sleeping people offer straightforward actions members of the public can take immediately. Centrepoint recommends donating sun hats, suncream and lightweight clothing, freezing water bottles to give longer‑lasting cooling, and signposting people to local day‑centres and libraries; another sector guide urges people to map water points and encourage councils to activate agreed emergency protocols to open cool spaces and offer temporary shelter. The Big Issue and other outreach groups advise contacting local frontline services or using referral tools such as Streetlink if someone appears to be in danger.

If you encounter a person showing signs of heat exhaustion or heatstroke, follow NHS guidance: get them out of direct sunlight, loosen tight clothing, offer cool fluids if they are conscious and able to drink, and apply cooling measures such as wet cloths. Call emergency services immediately if someone is confused, has a temperature over 40°C, is fainting, or is not sweating despite high temperature — all red flags for heatstroke. Where possible, alert local outreach teams so they can follow up and offer longer‑term support or accommodation.

The combination of wildfires and extreme temperatures underlines that heatwaves are not merely an environmental inconvenience but a public‑health challenge that magnifies social vulnerability. Sector bodies stress that the most effective protection comes from pre‑emptive, coordinated action: early activation of heat‑health plans, visible cooling hubs, boosted outreach and public awareness so that people at greatest risk are located, sheltered and treated before minor symptoms escalate into medical emergencies. In the absence of those systems, charities say, individual acts — offering water, suncream or a call to local support services — can still save lives.
