We have used Harmer Slater for the last 5 years since the start up of our business and we find them to be professional, extremely knowledgeable, and a pleasure to work with. Not only do they complete a very thorough and well-conducted audit, but they take an interest in our company beyond the formal requirements of the audit, have made some helpful suggestions, and engaged in a number of useful discussions.

We also find that we have had a consistent team which helps with a small audit and a partner who is whole heartedly engaged in our business and on hand for any questions we may have throughout the year. They offer both strong technical but at the same time pragmatic advice and we have found the team from partner level to junior to be highly competent and efficient.

Based on our experience we would certainly recommend Harmer Slater to anyone looking for a professional accountancy service.

Tim Slater of Harmer Slater prepares my business accounts and Frances Cummins deals with my personal and many of my family’s personal tax affairs.

Tim thinks like an FD not like an accountant and he’s well-suited to working with entrepreneurs. I’d happily recommend them both.
