Our mission

Helping everyone save enough to be comfortable in later life

The problem

Pensions are a huge societal problem with two route causes:

• People dont understand pensions
• People hate dealing with pensions

So 82% of people arent saving enough for retirement according to The Institute for Fiscal Studies.

We believe that the pensions industry is broken. Traditional providers with their outdated products and poor customer service have put people off saving. The world of work is rapidly changing and the pensions industry is falling further and further behind.

The result is were living through a silent savings crisis. We started Penfold to address this crisis and get more people saving more for their future by making pension saving easy accessible and engaging.

Our vision

How we help everyone adopt healthy saving habits

Weve done away with the legacy systems and processes that old-school providers are built on starting from scratch with our purpose-built pension platform which:

• Brings clarity and confidence about pensions

• Helps savers understand the when why and how of pensions
• Offers a seamless and low friction experience
• Has fantastic customer service when you need it

Our story

• Expansion: We expanded our pension to all individual savers in early 2021. Our pension can help everyone contribute transfer and engage with their pension savings. We started focusing on limited company directors and those in full-time work as well.
• Welcoming workplace: We launched our workplace pension in Autumn 2021. Pensions are one of the most expensive benefits companies offer. They dont work for employers or employees. We started offering the future of workplace pensions and have been listed by The Pensions Regulator.
