Mr Dean had been living for some years at Waltham House, which is an extra care scheme for older people run by Housing 21.
Helen Hart, locality manager for Housing 21 said:
During the Second World War, Reg Dean was stationed in Burma in the Far East.
Last year on his 110 birthday he told the Independent that he nearly did not return: "I nearly didn't come back from Burma, I was under shell fire so often.
"The second-in-command of our regiment was a friend and he was in the same trench with me when the shells were coming over. I said, 'What are you going to do when they come here?' He said: 'I'll lay about them with this kukri' – that's a Gurkha knife. Luckily, he didn't have to."
Britain's oldest man has died, aged 110 years and 63 days, friends have said.
Reg Dean, a former United Reform Church minister, died on Saturday, according to an announcement by the Dalesmen Male Voice Choir in Derbyshire.
He was the choir's life president, and helped to found the group in the 1980s.
Mr Dean, a former Army chaplain and teacher, survived two World Wars and witnessed 24 British prime ministers come and go.
He was born in Tunstall, Staffordshire, on November 4 1902, and became Britain's oldest man in June 2010 after the death of Stanley Lucas, 110, of Cornwall.
Reg Dean from Wirksworth in Derbyshire is today celebrating his 110th birthday as Britain's oldest man.
Born in Tunstall, Staffordshire, in 1902, Reg Dean served as an army chaplain during the Second World War.
In his 110 year's, Reg has seen many great changes: air travel developed from the Wright Brother's first flight in 1903, to the first person on the moon in 1969.
He's also witnessed two world wars, five monarchs and 22 prime ministers.
Reg has been alive 40,150 days.
