Berkshire's chief fire officer, Iain Cox, is awarded the Queen's Fire Service Medal.
Sir John led Reading into the top flight for the first time in their 135-year history.
He said: "Obviously it's a great honour and I feel very privileged.
"Everybody knows that I'm committed to the community of Reading in many ways and this is a manifestation of that.
"But you see anything is possible and I would like to offer that as a beacon of hope to young people today.
"My only disappointment is that my mother passed away one-and-a-half years ago and didn't see me get this."
