We started using Dyer & Co for our company accountancy and personal tax affairs. We were amazed at the standard of service we received. We can always get to speak to someone familiar with our companies. All work is completed promptly and the staff will ensure we hit all our deadlines so we avoid any penalties. I would happily recommend Dyer & Co in the future.

I recently employed the services of Dyer & Co to complete my Tax Return. I was extremely impressed with the level of customer service that they provided. They happily took the time to go through my accounts with me before submitting the Return on my behalf and I was extremely pleased with the result that they managed to achieve for me.
Simon Hughes
The level of service and co-operation in minimising tax liabilities since we have been using services of Dyer & Co has been excellent and they have helped my company to survive and prosper through difficult financial conditions. I would have no hesitation in recommending their services to any other business large or small who need an accountant who is interested in enabling their business to grow and prosper in the future.
