Goodman Masson staff have raised money for the charity Help for Heroes by dressing up as Superman.
The firm broke the world record for the largest number of people dressed as Superman with 180 staff members, friends and families wearing the blue jump suit, red shoes and cape.
Thousands of pounds were raised which will help to provide better facilities for wounded British servicemen and women.
Prior to this event, the largest gathering of Supermen was 122 participants in an event organised in Metropolis, Illinois in 2008.
Guy Hayward, chief executive of Goodman Masson, said: “Not only have we managed to break a world record but we have raised substantial funds to help support the fantastic and vital work carried out by Help for Heroes.
“This is a massive achievement and I would like to thank everyone that took part in helping us to become Guinness World Record breakers.”
