5/5 – Google Reviews

Real reviews from professionals, entrepreneurs and companies operating in the UK.

See how we help international founders and companies establish and grow in the UK — and what they say about working with us.

AccountsCo, now trading as Britannia Advisory, has supported our company for more than ten years, from the incorporation of Hyphen-UK Ltd through every stage of the company’s growth and operations. What initially impressed us was their strong expertise in international tax, UK VAT matters, and the UK / Italian tax treaty. Over the years, Simon and his team have consistently provided reliable, punctual, and highly professional support across all accounting and business matters related to our UK company. They have always been available whenever issues or questions arose, offering practical advice and dependable assistance with great attention to detail. I would strongly recommend Britannia Advisory to any international business looking for a trustworthy UK accounting and tax partner. Alessio Saraceno Hyphen-UK Ltd / Hyphen-Group s.r.l. (Italy)

Simon and his team have been an invaluable help in the UK – Simon negotiated a great deal for us on our first post-Covid restaurant and his team is instrumental in helping us meet our UK needs.

Salvatore AloeCEO, Berberè Pizzeria

Berberè Pizzeria

Italian sourdough pizzas in London

Matteo and Salvatore, two brothers from Calabria, studied Economics in Bologna. Just like every other penniless student, they ate lots of pizza. So, they opened their own restaurant. Now they have 21 restaurants in Italy and 5 restaurants in London. Best pizza in town!

Our work

We were initially engaged by 8 Slices Ltd (forerunner of Berberè in the UK) before Covid. During Covid we assisted the company with a phoenix-type restructuring and relaunch. Simon took on the role of part-time FD of the UK business and helped the brothers build to 5 restaurants in London. Britannia Advisory provides a full range of accountancy, tax and payroll services.

Our adventure in the UK is still in an early stage. It’s certainly made simpler by Simon and his team. It’s a great help having Rod as our UK HR director, particularly for banking and sponsorship licence matters.
