Andrew has been working in HMRC investigations for over 40 years.

Andrew began his career in HM Customs & Excise and subsequently moved to what is now HMRC. After completing his training he was a District Inspector and then transferred to Head Office as a fraud investigator in Enquiry Branch (now the Fraud Investigation Services) where he spent six years conducting Code of Practice 9 investigations on a wide variety of individuals, partnerships and companies. On leaving Enquiry Branch Andrew was appointed in charge of a number of Districts in London before leaving the Revenue to join Blyth Dutton a West End law firm.

Subsequently Andrew became a partner at a top 20 accountancy practice Casson Beckman and later took on the same role at Moores Rowland. From there Andrew and his team were invited to join Williams Jeffrey Barber, later rebranded Chiltern plc, one of the UK’s leading tax advisory firms. During that time Andrew’s team, which had by that time grown to 14 investigators, won the prestigious Best Tax Investigations team award at Tolley’s annual awards ceremony.  Andrew then headed the tax investigation team at Alvarez & Marsal Taxand LLP – a US professional services firm which he left in 2011 to set up his own practice.

Clients say that Andrew has an ability to get straight to the nub of the problem, is wise, assertive and brave when dealing with HMRC.
