About Key Finance

Committed to Excellence


Key Finance has been providing working capital support to some of the biggest companies across the globe for over 40 years. The long-term relationships we have with these blue chip businesses is testament to our reliability, our flexibility and our company ethos of getting the job done.

We’re incredibly proud of the reputation this family-run business has earned in that time and we welcome the opportunity to work with new clients of any size.

Our Chairman

Key Finance was established in 1987 by our Chairman John Mounsey who had the vision of establishing a new kind of financing, thanks to a long and successful career straddling both IT and leasing at blue chip corporations including IBM, ICL and ITEL.

He brought his vision for new leasing options to Key Finance, initially doing the same as he’d done previously – renting mainframes and PCs – but with ambitions to offer more, and to a wider spectrum of clients.

John wrote the first reference book on leasing in 1988, helped Hewlett Packard to develop its own lease strategy when PCs went mainstream in 1991 and – thanks to Key Finance’s fast-growing reputation in the world of finance – quickly attracted clients outside of the IT sector.

Since then Key Finance has helped some of the biggest international companies with finance options.

And whilst retaining those blue chip clients, Key Finance now works with companies of all sizes throughout the UK – and in many different sectors. But all have the same requirements: to grow their businesses, by securing bespoke and flexible finance.

Today, John Mounsey remains as Chairman of Key Finance, with his son Henry taking a front seat alongside the rest of the team. However the business practices, ideals and ethics remain the same as when Key Finance first started serving the IT community nearly 30 years ago.
