Ridgefield Consulting

Ridgefield Consulting is an independent firm of Chartered Accountants and Business Advisors, registered with both the ICAEW and ACCA. Based in Oxford, the practice is founded by father and son, Brian Thomas and Simon Thomas, who between them share over 50 years’ experience in the accounting industry. Today, the company is still family-run, with a growing team of young and dynamic accountants supporting them.

Ridgefield Consulting launched their rebrand in January 2019 alongside a fresh new website. After considerable growth from the previous two years, they are firmly establishing themselves as the go-to accountancy firm for start-ups, scale-ups, Biotechs and those seeking expert R&D tax credit, SEIS or EIS services.

Their refreshing and unique approach means their focus is not simply completing a tax return, but putting the client’s financial objective at the forefront before applying their expert tax knowledge to devise the most efficient strategy to achieve the goal. They are particularly well suited to support ambitious small to medium sized businesses seeking growth.

Meet the experts

Simon Thomas

Managing Director

Simon Thomas is the managing director of Ridgefield Consulting, founded in 2010. With real entrepreneurial spirit, commercial acumen and instinct for the numbers, he’s successfully grown the business year on year. Not unfamiliar with the challenges of running your own business, it’s perhaps no surprise that Simon connects well with other local small business owners around Oxford. His expertise as an accountant originates from previously working for one of London’s Top 4 firms as an auditor, yet his specialism now focuses on R&D tax credits and SEIS/EIS tax schemes for the Biotech sector.

Chloe Lloyd

Admin & Accounts Assistant

Chloe has a demanding role in the office and possibly wears the most hats. As the admin & accounts assistant, she’s the front of house representative and the client’s first port of call for an update on the status of their work or their billing. Her various responsibilities around the office mean she’s continually optimising and streamlining internal processes from invoicing, debt chasing, procurement and more to ensure the whole office is running as efficiently as possible.
