Hillier Hopkins LLP

Chartered Accountants & Tax Advisers

Call +44 (0)330 024 3200 and discover how we can help you.

From our roots in Beds and Herts, we have expanded across the region and now have offices in London, Milton Keynes and Watford. Our clients include individuals and businesses ranging from small family enterprises to large international companies.

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.

Alex Bottom, Managing Principal

“Over the years, 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.”

"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
