According to the lender, it is only the second building society to be become accredited.
The mutual has agreed to perform against the 10 components and commit to positive change to remain certified by the organisation.
The Good Business Charter is a not-for-profit organisation run by volunteers, and it is supported by the Confederation of British Industry as well as the Trades Union Congress.
In addition, the charter focuses on 10 key business areas designed to improve the wellbeing of employees whilst recognising responsible businesses.
The 10 agreed components are the real living wage, fairer hours and contracts, employee wellbeing, employee representation, diversity and inclusion, environmental responsibility, paying fair tax, commitment to customers, ethical sourcing, and prompt payment.
In order to receive accreditation, a company must meet all 10 obligations as detailed by the charter.
Colin Field, chief executive at Saffron Building Society, said: “At Saffron Building Society we are incredibly proud to have joined the Good Business Charter.
“Our society values are community, service, responsibility, and problem solving – all of which are cared deeply for by the GBC.
“We wanted to get behind an accreditation that was meaningful and aligned with our values.
“The GBC demonstrates how passionately we care about our people and our communities under our Amazing Employer Brand; the GBC upholds the values closest to us – supporting the real living wage, employee wellbeing, prompt payment, commitment to customers, environment and more.
“We will continue to positively support the GBC and make a sustainable difference to our colleagues, partners and communities.”
