Mansfield Building Society is celebrating 150 years of serving savers, borrowers and the local community with a raft of events throughout 2020.
The society was officially formed on 18 January 1870 following a meeting at Mansfield Town Hall and now serves around 18,500 members.
Paul Wheeler, deputy chief executive at Mansfield Building Society, said: “When the founding members voted to establish a building society in Mansfield all those years ago, they were passionate about creating an organisation that enabled people to save and supported those wanting to buy their own homes.
“Today, we continually put people first by offering a diverse and flexible range of mortgage solutions, valuing the loyalty of our existing members and actively supporting the future development of our local community through our Charitable Trust, Community Support Scheme and staff volunteering.
“We’re looking forward to making a real difference in our 150th year with a range of activities.
“We’ve chosen to celebrate being ‘150 years young’ because we intend to be part of the financial landscape for many years to come.”
In celebration, there is a commitment to plant 600 oak trees with Sherwood Forest Trust and there will be financial education booklets created for younger savers.
Limited edition products will also feature during the course of the year.
The society has said it will donate 150 volunteer days throughout the year.
