The fire is affecting a large part of a restaurant within the park, and crews are working hard to bring it under control. There were a lot of flames and the area was quite smoky when we arrived, but thankfully firefighters are making very good progress. Luckily it doesn't seem like anyone has been involved or injured. We're working with our partners at Surrey Fire and Rescue Service along with the police and ambulance services to ensure the incident is brought safely under control.
The fire at Chessington World of Adventure is in a cafe which was being used as Santa's grotto over the Christmas period.
During the festive season the park opens for restricted hours and with access just to part of the zoo, this includes the Creaky cafe where visitors could visit the 'Night before Christmas - A Magical Adventure' attraction.
We have a crew, an officer and our hazardous area response team on scene at a fire in Chessington, but currently no reports of any injuries.
Theme park fire update: the park wasn't open to the public when the fire broke out, and no one is believed to be injured. #chessington
