Marsden Building Society, originally named ‘The Great and Little Marsden Permanent Benefit Building Society’, was established in 1860 in Nelson, Lancashire. This mutual society was founded with a vision to build something better for the local community. Over the years, Marsden Building Society has grown, consistently serving its members with savings and mortgages. Today, it is the largest Lancashire-based building society, with assets reaching £733 million in 2022.

The Marsden prides itself in being a great place to work, with over 100 colleagues spread across its branch network and Principal Office. It is an organisation with a 'family feel', upheld by its core values which include making a lasting impression, being passionate about people, and working together. The strategy that guides the society is collaboratively developed by the Board and the Senior Leadership Team, with key messages disseminated via meetings, an intranet, and an internal newsletter called "SPOT-LITE". To ensure all voices are heard, the society also runs a "Moving Marsden Forward" group, where colleagues from all departments meet to discuss key issues and review suggestions made through the "Colleague Voice" online forum.

The Marsden Building Society fosters a culture of inclusivity, with the Senior Leadership Team leading by example, promoting inclusive working practices, and maintaining open lines of communication. The society encourages colleagues to share ideas, contribute to the society, and engage with each other, regardless of their location. This culture is felt across all locations, creating a unique and supportive environment.
