Our story

Our story began in 1933....

Hillier Hopkins began life in 1933 as Lewis Hillier & Co accountants in Luton, expanding into Hemel Hempstead soon after. Founder John Hillier was joined by Len Hopkins and the firm became Hillier Hopkins & Co. Since then, we have continued to expand thanks to the wonderful people throughout our firm’s history who have shaped its growth and development.

Over the years Hillier Hopkins has trained hundreds of qualified accountants and advised many thousands of individuals, sole traders, partnerships and companies including PLCs and financial institutions. We have a long history of supporting local causes and dedicating time and expertise to local community bodies and professional associations.

Although the firm’s founders have sadly passed away, their legacy lives on in our “friendly expertise” ethos and our commitment to remaining independent and maintaining the highest possible technical, ethical and professional standards.

"Nothing is too much trouble"

"I have the best relationship I have ever had with an auditing company - the team are professional but they are incredibly friendly and approachable. Nothing is too much trouble and they are so supportive. Wayne Arrowsmith is superb, he works relentlessly to ensure the audit goes smoothly, and he offers a calming and reassuring voice."
Rich King

"Conscientious and dedicated"

"Hillier Hopkins provide an excellent service. I have always found them to be responsive, conscientious and extremely dedicated."
Javid Khan

"A genuine friend of the business."

"They maintain a very high level of client service which, at a professional level, have made them a trusted adviser and on a personal level, a genuine friend of the business."
RPM London

"Invaluable practical advice"

"We have worked with Meeten Nathwani at Hillier Hopkins for over seven years and, as a small business, have found his responsiveness and good, practical advice invaluable. The experience has been in marked contrast to other professional advisers who tended rather to 'sit on the fence' and outline alternatives rather than then advising on the right course of action."
Keith Evans

"Open and reactive relationship"

"The compliance and reporting support is built around an open and reactive relationship with the directors and accounting team."
Antal International

Alex Bottom, Managing Principal

“Since our beginnings, Hillier Hopkins has expanded steadily in size and geographic reach to become one of the region’s leading independent firms. We are very fortunate  in that throughout our growth we have been able to attract a hugely talented team who continue to deliver our ethos of “friendly expertise”. Our focus is on preserving this ethos and working hard to ensure that our clients prosper above all else.

It’s important to us to support the communities we work in and the world we live in. We have a growing commitment to the UNs Sustainable Development Goals and are working on an environmental policy and initiative to reduce our environmental impact on the world.”

Corporate social responsibility

We continue to implement new measures to decrease our environmental impact and reduce wastage which includes; working towards a paperless office by investing in document management software; and centralising our business teams, to reduce the need for travel between offices.
