Fires across England and Wales have prompted a national government alert warning people not to light anything that could spark a wildfire.

The warning on Friday evening came as it was revealed 19 homes were destroyed and a further 18 damaged in a huge fire in Stourbridge, West Midlands, that spread rapidly through grass and woodland on Thursday before damaging homes.

Prime Minister Andy Burnham told members of the public to take the warning “seriously”, adding it was triggered at the request of firefighters.

West Midlands Fire Service chief fire officer Simon Tuhill said the Stourbridge blaze was one of the most significant incidents the service had ever dealt with.

It was one of several fires being dealt with across England and Wales on Friday.

  • In Hampshire, firefighters spent a sixth day tackling a wildfire in the New Forest, Hampshire, which broke out on Sunday.

  • Sixteen emergencies were tackled by Norfolk Fire and Rescue Service on Thursday afternoon, including a fire at Mousehold Heath, off Gurney Road in the city.

  • Elsewhere in the West Midlands fires caused extensive damage in Warstock and Kings Norton, Birmingham on Thursday. A 55-year-old man was arrested on suspicion of arson with intent to endanger life .

  • In Stoke-on-Trent on Thursday four homes in Sandyford were destroyed, with other properties damaged. Two people were arrested on suspicion of arson. Six firefighters were taken to hospital due to smoke inhalation and heat exhaustion.

  • In Willenhall, West Midlands, at least three homes and several gardens were destroyed in fires on Stonehouse Avenue and Harry Perks Street.

Investigators said they were working with other emergency services to establish how the Stourbridge fire started, with police saying they were keeping an open mind.

Some of the worst-affected areas have been cordoned off and many residents who were evacuated, including the Bishop of Dudley, the Right Reverand Martin Gorick, have not been able to return home.
