Speaking to the media outside the court building, Warwickshire's community safety spokesman, councillor Richard Hobbs, apologised for the fire authority's failings.
Mr Hobbs said:
We pleaded guilty to the charge brought under the Health and Safety Act because we recognised and accepted that there were failings on our part back in 2007.
Since then, as the judge emphasised today, Warwickshire has become a model fire authority and our training is some of the finest in the country.
No fire service can guarantee that nothing will ever go wrong again but we are confident that our service is as safe as it can be.We will always remember the bravery of those who died in the service of their community and we offer our deepest condolences to their families and friends.
