All of this means you are able to confirm that your customers and suppliers are genuine businesses, whilst keeping your business on the right side of the law.

Our team are skilled professionals who understand your industry and have a detailed understanding of HMRC’s requirements. Our Technical Director and Technical Consultants have over 45 years’ combined experience in due diligence and regulatory requirements and our services are often called upon to prepare due diligence reports on companies based anywhere in the world.

Regularly satisfy HMRC requirements

Our services can help any business whose industry is regulated and affected by HMRC notices and due diligence requirements, as well as businesses that need general due diligence assistance and support. However, with HMRC’s heavy concentration on regulating the alcohol industry, we currently provide high levels of support and services to businesses of all sizes within the alcohol industry, from small wholesalers to multi-site national cash and carries.

And whilst HMRC will never provide a seal of approval to any third party service provider, our reports have satisfied HMRC requirements on countless occasions and we have been commended for the high level and quality of the due diligence we provide. Many of our reports and policies have been successfully used to assist clients in the Magistrates Court, First and Upper Tier Tax Tribunals, Crown Court and the High Court.

With strong working partnerships, including our new Joint Venture, we can resolve any financial or legal issues you have with HMRC on both a national and international level. And we can also expertly assist with criminal and civil proceedings against or enacted by HMRC.
