Branch manager John Boyd cut the opening ribbon at Queen Street with mascot Hamish and players from the Scottish Women’s Premier League, which the Society sponsors.

With 33,000 members, Scottish Building Society is the world’s oldest building society, having celebrated its 170th birthday last year.

As well Glasgow, the Society operates branches in Edinburgh, Galashiels, Aberdeen, Troon and Inverness.

The Society has seen a fifth consecutive year of mortgage book growth with pre-tax profits ahead of plan to £1.03 million.

Paul Denton, chief executive officer, said it was a £350,000 investment in Glasgow and the high street.

He added: “We are delighted to open a new branch here in Scotland’s largest city. Although we have had a presence here, we are thrilled to finally have a home to call our own.”

“Bank branches are disappearing from towns and city centres, often this results in customers feeling ill-ease as they have nowhere to physically go.

“We believe our branches should be a point of presence within communities, whereby they represent brand assurance as well a place for members to transact. They can also be a meeting place for the wider community and key stakeholders, such as our mortgage intermediary partners.”

The Society’s initial £350,000 investment means it now has six branches in Scotland with over 30 sites across Scotland through agency partnerships with solicitors and accountants.
