Police visited the man’s home in Northgate, off Golden Hill Lane, on Thursday afternoon (March 17) to carry out a welfare check.
After receiving no answer, officers entered the home where they found the man, aged in his mid-50s, deceased in the kitchen.
He has since been named locally as Billy Bebbington, a familiar and friendly face to many in Leyland.
Lancashire Police said it has completed its investigation and his death is not being treated as suspicious.
The cause has not been confirmed but the force said a file will be passed to HM Coroner.
A police spokesman said: “We were called to an address in Northgate, Leyland, at 1.16pm on March 17 following reports of a concern for welfare.
"Officers have attended and sadly found a man deceased inside the property. Our thoughts remain with his loved ones at this time.
