"We have used Stewart & Co's accountancy and payroll services for the last 15 months. They have made the whole process so easy when migrating over from our old accountants. They are always happy to help and will take calls to explain anything we don't understand."

Stewart & Co. have been our auditors for a number of years. We also use their services for production of our statutory accounts and tax returns. We have stayed with Stewart & Co. as we find their approach efficient and practical. They are happy to be flexible to meet our deadlines. They understand our business well, due to the length of the relationship and the stability of the audit team. We appreciate that we can pick up the phone and ask for some general advice (without this immediately being followed by an invoice). We recently completed an acquisition. Throughout the process we were able to lean on Stewart & Co.'s experience and they were happy to provide informal advice. We have engaged them for the audit of the acquisition now that the transaction has completed.
