People urged not to light barbecues, campfires or anything else that could spark fire during period of extreme heat

Millions of people across England and Wales have received an emergency alert to their phones as the government warns against activities that could start fires.

The deputy prime minister, Louise Haigh, said it was the most extensive use to date of the emergency alert system, with phones beaming a siren noise about 7pm, with the warning “there is a serious risk of wildfires nationally”.

People have been urged not to light barbecues, campfires, fireworks or anything else that could spark a fire while the wildfire risk remains high. They have also been urged to call 999 immediately if they spot a fire.

Andy Burnham spent time in Stourbridge on Friday after homes were destroyed and residents were left injured by a series of fires in the West Midlands. The prime minister warned that Britain “is a tinderbox right now” with the public set for a “difficult weekend”.

He announced a temporary national ban on the sale of disposable barbecues to be enforced immediately. The ban will remain in place as long as the risk of wildfires remains high.

The military was called in to assist stretched emergency services in south Wales. About 100 personnel have been deployed with about 100 more due to arrive on Friday evening, distributing water, moving equipment and personnel and providing logistical support.

It has been a record year of wildfires in England and Wales: the number of incidents so far this year has passed the 1,017 of 2025. Fire services have declared 11 major incidents in the last 24 hours.

Haigh said: “In response to the continued risk proposed by wildfires, the government has taken the decision to issue an emergency alert to England and Wales. This is the most extensive use of the UK’s emergency alert system in response to an active incident, and reflects the seriousness with which the government is acting to safeguard people and property.

“During this period of extreme heat, we are asking people to take simple steps to limit the risk of further fires. By following the safety guidance, everyone can play their part in protecting local communities and supporting our frontline services who are working around the clock to keep people safe.

“The government will continue to provide every assistance to communities being impacted by these fires, including the deployment of 100 additional military personnel in major incident areas.”
