I set my F1 Catering company up in 1998 and was recommended Mensis as accountants.

Since then, they have supported my F1 catering company with accurate accountancy looking after the difficult overseas taxation laws, VAT, Inland Revenue documentation etc.

For almost twenty years they have always been my financial rock and at the end of the phone (in those early days no internet!).

We have only lasted in F1 for so long because our company foundations are strong, one of those supporting structures is Mensis.

There are two things I trust in this world My mums cooking and Mensis accountants.
