International services

Working with one of the UK’s leading accountancy providers in the international services department, our founder, Martin Brennan, developed extensive knowledge and expertise to support businesses expanding into the UK for the first time.

We understand how daunting it can be expanding into a new territory. Our team will take the time to review your position and explain your obligations for setting up business in the UK, whilst taking the vast majority of work off your hands.

International support

We can support your expansion into the UK from initial company setup, VAT registration and assessment of cross-border VAT issues, payroll and HR support, transfer pricing and many other common issues associated with setting up in the UK for the first time.

We also have a global support network that assist in expanding into new territories.
