If you have employed an accountant to do some work for you, and they have not provided a satisfactory service, you can use this letter to make a complaint to them. An unsatisfactory service can relate to the quality of the work done by the accountant, but can extend beyond that to cover other matters, such as whether the work was done on time, or whether the accountant kept you informed or returned your messages. The letter asks the accountant to provide you with their proposal for rectifying the problem, and demands compensation from them if you have suffered financial or other losses. If you receive no satisfactory response to this letter and the accountant is chartered or certified, use 'Complaint to an accountant’s governing body'.
