Swansea Building Society has made its finance director, Nathan Griffiths, deputy chief executive, as the city’s own mutual plans for its future leadership.
He will work alongside chief executive Alun Williams as part of what the society calls its long-term succession planning. The society will now recruit a new finance director.
Founded in 1923 and run from Cradock Street, it says it is one of only three mutual building societies left in Wales, and the only one with its headquarters in south west Wales. It had total assets of £715m at the end of 2025.
From Deloitte to Cradock Street: Nathan Griffiths’ career
Mr Griffiths joined as finance director in July 2019 from Monmouthshire Building Society, where he had been group financial controller since 2015.
He began his career at Deloitte, spending eight years in its financial services assurance and advisory practice and rising to senior manager. He is a chartered accountant and a fellow of the Institute of Chartered Accountants in England and Wales.
At Swansea he has had executive responsibility for finance, treasury, IT and HR, and chairs the society’s assets and liabilities committee. He has recently completed the Henley Business School leadership programme, the society says.
‘A natural next step’, says chief executive Alun Williams
Mr Williams said succession planning was something the society had “given considerable thought and attention to”.
He said Mr Griffiths “has made a significant contribution since joining us in 2019”, and called the appointment “a natural next step in his development as a senior leader”.
Mr Griffiths said he was “incredibly proud” to take on the role. “Swansea Building Society is an organisation I care deeply about,” he said.
As the society grows, he said, it was important to “retain the values, relationships and focus on our members that make the Society what it is”.
A building society opening branches while banks close them
The appointment comes as the society expands. In August it bought the former TSB on Blue Street in Carmarthen for a bigger office, due to open in early March 2027.
Earlier this year it launched a new app and announced plans for a branch in Abergavenny, alongside its offices in Swansea, Mumbles, Carmarthen and Cowbridge.
It lent £117.5m in new mortgages during 2025 and made £6.2m profit before tax, the society reported in March.
Details of the recruitment for a new finance director will be announced separately, it said.
