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 Traditional providers, with their outdated products and poor customer service, have put people off saving.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

Creates a sense of security about savers financial future

Increases visibility of savings and investments

Gives a sense of ownership and control over money

Helps saversrstand the when, why and how of pensions

Offers a seamless and low friction experience

Has fantastic customer service when you need it

Our story

We started as the pension for the self-employed in 2019. Up to 80% of self-employed people weren saving into a pension. We set out to solve that by building a flexible and straightforward pension that got self-employed saving.

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.

The future is bright: We\''ve got over 100,000 users and thousands of business clients. And weve still got so much further to go to make sure everyone is saving enough for a great retirement.

Our values

Be a great place to work

Challenge directly with empathy

Work from first principles

Move fast

Be accountable
