As you can imagine we enjoy taking responsibility for your tax and VAT returns, management accounts, cash flow forecasts, payroll, auto-enrolment, financial reports and statements. They are all important for running a business today. Yet, the most important element of our work with you is helping to ensure your success.

The less you have to worry about the better for you and your business

If you are expecting a one-size-fits all service you’ll be disappointed. Our advice, support and recommendations will be based on identifying tax savings, undertaking personal, business and corporate tax planning and instigating taxation health checks specific to your situation.

“CGA handles our accounting and payroll. They have been working with Bivouac since I worked on my own and have helped me to grow the business on firm financial foundations, over the course of 10 years. They are always a step ahead of the game…”

Michelle Thirsk FCCA ATT(Fellow) FMAAT – Director

Back in July 1991 Chelle joined CGA and, today, as owner and Director, Chelle has helped shape CGA into a dynamic, paperless accountancy service that focuses on offering more: more ideas, more good advice, more care and attention.

Responsible for the direction of CGA, Chelle brings an extra layer of consulting expertise across the challenges of running your own business and getting the balance and numbers right. Unofficially known as the ‘Head of Non-compliance’, Chelle can add pounds to your bottom line, over and above the more usual tax and accounting compliancy that comes as standard.

Passionate about horse racing and Rugby Union, Chelle inhabits the Knavesmire and Twickenham, enjoys a good Zumba party and Fight Fit, as well as regular eye watering challenges ticked off her bucket list, including jumping out of planes, zorbing and aerial assault courses. If Chelle has to relax it’s with a good bottle of wine and a thriller.

Claire loves an annual jaunt to Cheltenham for the Gold Cup and confesses to being a Zumba and soup addict (but not at the same time).
