About Us

Specialist accountancy for contractors and consultants

Martin Cook is a Chartered Accountant and the owner and Managing Director of Martin Cook Accounting Services Limited. He qualified as a Chartered Accountant with Price Waterhouse Coopers in 1993.

Since 2001, Martin has been providing clients with high-quality accounting and tax advice. In 2009, the practice began specialising in accounting and tax services for contractors and consultants, with a particular focus on IT contractors, Oil & Gas contractors, and offshore contractors.

This clear focus has helped Martin to build deep, practical expertise in the contracting sector, including the specific tax and compliance challenges faced by contractors working in the UK. 

At Martin Cook Accounting Services, we believe in giving you:

  • A personal service (we are not a "contractor accounting factory")

  • One contact point and unlimited access to a CA when required

  • A responsive service with queries and emails answered swiftly

  • A tailored plan helping to minimise your tax costs where possible

  • Peace of mind while we take care of your compliance requirements

From establishing the business to explaining each step as we progressed, Martin's guidance has been invaluable. Regular catch-up sessions have been particularly beneficial, ensuring that we remain on the right track and providing me with peace of mind. This allowed me to focus on my role in IT security, confident that the business finances were being expertly managed.
