The application was submitted in November after members unanimously voted in favour of the proposal.
As a charity, the Glendale Agricultural Society will be able to apply for grants from both local organisations and top charitable funders including Funding Central and the National Lottery.
The Glendale Show and Children’s Countryside Day will continue as normal, but they will each have the added benefit of being run by a charity.
Lord Joicey, president, said: “Being a registered charity allows the society to apply for funds that it has hitherto not been able to attract.
“Its activities and objectives have always been charitable, and I am thrilled that the Charity Commission have agreed to recognise this by granting full charitable status.”
Rachael Tait, secretary, added: “This is truly a defining moment in the society’s long history, and it excites me greatly to see what the future holds.”
