A significant wildfire on Tintwistle Moor, near Glossop, has been officially declared a major incident by fire services, three weeks after it first broke out. The blaze, which ignited on 24 June 2026 during a period of record-breaking June temperatures, initially affected an area of approximately 400 square metres. Despite initial efforts that saw crews leave the scene on 2 July after damping down, a new heatwave brought renewed flare-ups, prompting firefighters to return to the moor.
By Sunday, 12 July 2026, the fire had escalated, impacting around 260 hectares (642 acres) of moorland and woodland. Deputy Chief Fire Officer Clive Stanbrook explained that the major incident declaration was a response to the extensive resources required, involving not only numerous fire appliances but also partners such as the RSPB, United Utilities, and mountain rescue teams. High winds and extreme heat contributed to the fire's rapid spread, with some fronts advancing at an estimated 10 metres per minute.
The cause of the Tintwistle Moor fire remains under investigation. However, Stanbrook highlighted that many fires in the area are accidentally started by visitors. He issued a strong plea to the public to avoid actions such as using barbecues or carelessly discarding cigarettes, particularly in the current tinder-dry conditions following weeks without rain. Such fires, he emphasised, inflict 'generational damage' on the region's rare wildlife and vital habitats.
While the duration of the current blaze is uncertain, fire officials acknowledge that it is not uncommon for large-scale moorland wildfires to persist for several weeks. Stanbrook recalled a previous incident at Tintwistle in 2018 that lasted 28 days from start to finish. Currently, ten fire engines are on Tintwistle Moor, focused on preventing further spread by cutting away vegetation and establishing two firebreaks to the west and east, aiming to protect areas including the Pennine Way.
The Tintwistle Moor incident is one of several major wildfires occupying emergency services across the UK in the wake of the recent heatwave. Other significant blazes have been reported in Conwy, North Wales, leading to evacuations, and near Dovestone Reservoir in Greater Manchester, where an arrest was made on suspicion of arson. Further wildfires also occurred over the weekend in Hampshire, Durham, West Sussex, East Sussex, Devon, and Somerset, underscoring the widespread impact of the dry conditions.
