Who we are

About MHA Carpenter Box

Our thinking starts with you. Our focus is around understanding what our clients need. We provide great business advice based on having the right people who know how to provide solutions, develop trust and build long term relationships.

We are an award-winning sector focused firm of Chartered Accountants, Tax and Business Advisers based in Gatwick, Worthing, Brighton and Chichester with a headcount of over 180. To serve you better we are organised into specialist business groups, offering a comprehensive range of services to businesses and private clients in the South East and beyond.

We are passionate about helping businesses to grow and reach their full potential. Our approach aims to provide in depth business and tax advice with a breadth and depth of service that covers almost every aspect you can think of. Whether you’re an entrepreneur, an MD or FD of a large business, or an owner manager running an established business, we will work with you to help you become tax efficient, increase your profitability and look after your personal finances.


We have been giving good advice for over 95 years. Whilst it’s lovely to have such a long pedigree we understand that to be able to advise businesses on the best way forward, we have to be forward looking ourselves something we have taken to heart. We are at the forefront of cloud accountancy and are recognised as a national thought leader. Our approach has won us national, regional and local awards making us one of the most respected accountancy, tax and business advice practices in the region.

Our success is down to the expertise of some of the brightest accountants, auditors, financial advisers and tax specialists in the business. We are a member of MHA, a national association of independent accountants all sharing a similar service led ethos to ourselves. MHA gives MHA Carpenter Box the ability to help larger clients with specialist needs and acts as a fantastic national knowledge resource for any unusual issues that might arise. Through MHA, we are also a member of Baker Tilly International giving our clients access to a global network of trusted advisers – ever more important as the UK fights to re-establish itself as an independent global trading nation.

An award winning firm

We were named Mid-Tier Innovation Firm of the Year at the prestigious British Accountancy Awards 2019. This award recognised our firm’s dedication to finding the most innovative approach to business strategy and client service.

In 2019 our tax team were a finalist in the Tolley Taxation Awards for Best Tax Practice in a Regional Firm. We have also been named in the top 5 for both Large Firm and Innovative Firm in the 2019 Accounting Excellence Awards.

In 2018, we won the large Business of the Year award at the 2018 Gatwick Diamond Business Awards. We scored extremely strongly across many areas, including client service, industry knowledge, innovative use of IT and making a difference to clients. In particular, the judges noted:

“They go above and beyond when it comes to serving their customers, through their expert knowledge, and consistently look for new and innovative ways to add value to their clients. They are truly passionate about your business. They do an incredible amount of work for their community and have raised thousands of pounds to help local good causes.”

In 2016, we were named Xero’s UK Accounting Partner of the Year, from the leading cloud accounting software provider.

That’s why MHA Carpenter Box clients and professional contacts continue to recommend us every day.
