Who We Are

Specialist Accountants & Tax Advisors For The Security Industry

Whittaker & Co, founded by Anna Cooperwhite, a former member of the WRAC and Royal Signals, specialises in providing customised accounting services tailored to the security industry. Our strong dedication to the security sector, coupled with our extensive expertise in all aspects of accounting, ensures the safeguarding of your financial success and offers practical solutions for businesses across various sectors. With a deep understanding of the unique financial challenges faced by individuals and enterprises in the security sector, we have earned a reputation as a trusted source for expert tax advice and steadfast support.

Our journey began when Anna’s husband, John, concluded his 18-year military career, serving in units such as the Coldstream Guards, the Welsh Guards, 7 Parachute Regiment, and the Gurkha regiment in Brunei. Transitioning to a security contractor role in Iraq, John realised the financial potential of his new career. However, his colleagues often struggled with tax-related matters. Anna stepped in to assist them with their tax returns, laying the foundation for Whittaker & Co.

While John continued his work in Iraq for another 9 years, Whittaker & Co steadily expanded its client base. Our reputation for providing practical advice and excellent customer service continued to grow. Since our establishment in 2004, Whittaker & Co has developed into a dedicated team of tax advisors, accountants, and account managers committed to meeting our clients’ accounting needs, assisting clients working overseas and in the UK, and guiding them towards tax-efficient solutions.

Our Promise


 At Whittaker & Co we like to offer you a personal service and unlike other Accountants, we like to remain in contact with our clients throughout the year to ensure there are no nasty surprises when dealing with the Taxman!

As a result, we understand that it can be a daunting task when dealing with your own tax for the first time. Consequently, our specialists always try to provide our clients with the information they require in plain English.



 Over many years we have learnt that HMRC is not the most straightforward in the information they provide. For example, the rules on Non-residency is 101 pages long!

We aim to cut through the jargon and supply you with simple, honest advice. Therefore, you retain as much of the money you have worked hard to earn.



 We pride ourselves on understanding the needs of our clients. Within our team, we have vast experience of dealing with the frustrations and concerns common to all businesses and individuals.

We all share a common enthusiasm to deliver a personal, high-quality service. And we all have individual niche areas of specialism and wide-ranging experience.

Our range of services and resources allow us to meet our clients’ needs quickly and efficiently, often exceeding expectations.
