More than £900 was raised for a diabetes charity at a quiz night held in Bushey Heath.
The Michael Green Foundation hosted the night at the Three Crowns.
Joanne Green, who founded the charity, said: "£900 is a fantastic sum to raise and much more than we ever expected.
"It was a fun evening and the place was packed with friends and supporters, along with the pub regulars who help to support these local charity events."
The latest project is to fund a pilot scheme for a specially trained dietician to work with the unit and help advise patients on their condition.
Mr Duffy, pub landlord, said: "I have always enjoyed the cheque reveal but above all, I and all of our regulars enjoy making a difference to people’s lives and above all helping people with a passion for a cause."
