"Tom was a highly valued colleague and friend and brought a smile and sunshine to everyone he met. He loved his job and helping people and was a truly exceptional person. It was an honour to have known him and have had him as part of the Avery family.

"Needless to say, the entire team are devastated but our immediate thoughts are with his wife and family and all those directly affected by the incident."

The company thanked its customers for its messages of support.
