About Lewis & Co.
Independent, approachable and focused on what counts

Lewis & Co is a small, friendly team of accountants and tax advisers based in Southborough, Tunbridge Wells. We’ve been supporting individuals and businesses across Kent and Sussex since 1986, offering straightforward advice and reliable support in all areas of accountancy, tax and financial planning.

We believe good advice starts with listening. Our work is tailored to your specific needs – never based on a template or a standard package. You might be you’re running a business, planning for retirement or managing your personal tax affairs. Whatever your situation, we’ll take the time to get to know it properly and give you advice that’s practical, proactive and always easy to understand.

A team you can rely on

Lewis & Co. was established by Barnaby Lewis and has been part of the Southborough community for almost 40 years. Gary Cornwell first joined the firm in 2003, initially helping out during his work experience and during the holidays and then staying on full time. He later qualified as an accountant and when Barnaby retired in 2016, Gary bought the business and continues to run it today.

We’re proud to support local events, charities and residents, and we sponsor Tonbridge Angels Football Club.

The current team has worked together since 2018. With three full-time accountants and one administrator, we’re a close-knit team – so you’ll always speak to someone who knows you and your circumstances.

Our vision and values

We aim to build long-term relationships based on trust, not just transactions. We look after our clients throughout their time with us and believe communication is key – we meet our clients face-to-face wherever possible.

Our clients value us for being friendly, responsive and dependable. We focus on giving jargon-free advice tailored to each person’s needs.

Who we work with

We support a wide range of individuals and businesses, including:

  • Sole traders and limited companies
  • Start-ups and growing businesses
  • Landlords, retirees and high earners
  • Expats and non-domiciled individuals
  • People looking for clear, sensible advice on everything from tax returns to long-term planning

If you're looking for expert support from accountants who speak your language, we'd love to hear from you.
