Our Services
It is important for any business to always pay the appropriate amount of tax, as established by HM Revenue and Customs (HMRC).
One particular area of maintaining a business that is at once crucial and incredibly challenging is keeping up to date with any new legislation.
Small businesses employ a bookkeeper, either in-house or outsourced, who is responsible for running the management accounts of the company
The UK market offers many opportunities for establishing a business. One of the most popular choices among them is a limited company.
Vat regulations are ever-present in most areas of business. No matter where you look, Vat is always present in every aspect of your company's actions.
Bookkeeping is a necessary aspect of any business, so it is always a good idea to make sure your company does it thoroughly and efficiently.

Britannia Accountancy is a professional and proactive firm that have served all my financial requirements for the past 5 years. It is highly tailored to my needs and there is always someone available if any queries or questions need answering. A professional, friendly and supportive service that I can highly recommend.


I’ve been using Britannia Accountancy Service for well over 10 years for all my businesses. We’ve been extremely happy with their personal service. You know who you’re speaking to and you get replies and work done quickly. I would be very happy to recommend BAS to any small or medium business like ours.


I have referred quite a few people to BAS and in difficult situations, we got used to “Well, call them; they will know how to deal with this”. This is, in my understanding, a very good indication of the level of service


As a new company formed just six months ago we have been very lucky to have had Britannia Accountancy Services recommended to us. BAS have been a great help to us in these early stages of our business. They are helpful, offering good advice and have always responded very quickly when we have asked for help. In addition, our payroll and VAT returns have been completed in good time and professionally presented. We would happily recommend them to anybody.


We have been a loyal customer of Britannia Accountancy for over 5 years. Service provided always to perfection, timely procedures, sound advice and support whenever needed. BAS have a very professional and knowledgeable team in many additional fields, including export, customs and global trading. They provide excellent support in Russian and English which is a real bonus. Very highly recommended.
