Whittaker & Co was set up by, ex-WRAC and Royal Signals, Anna Cooperwhite to be specialist accountants to the security industry.

Anna’s husband John, left the armed forces after an 18 year career, which included service in the Coldstream Guards, the Welsh Guards, 7 Parachute Regiment and in the Gurkha regiment in Brunei.

John started a career as a security contractor in Iraq, and quickly found that the role was well paid; however none of his colleagues knew what their tax responsibilities were.

The Security Industry – Our Focus

Anna Cooperwhite (Owner) and Steph Davies (Non-Res Director) quickly found that clients working in the growing security industry abroad were offered minimal information about their tax responsibilities. The companies contractors worked for didn’t want any tax liabilities so ensured that their contractors were responsible for their own tax.
With the rise in piracy back in 2010, this resulted in a massive amount of security contractors moving to protecting vessels. The tax regulations for mariners are different to land-based contractors and Whittaker & Co started to manage accounts for the Maritime Security Contractors.
Accountacy For a Limited Company. One trading option for a business is to operate as a limited company. This will provide access to a number of tax planning strategies and limited liability status.

UK Based Ltd Companies

A limited company is a distinct legal entity that is able to enter into contracts in its own name. The fact that the company is a separate legal entity from its owners is very important as it means that all the company’s liabilities are the responsibility of the company – not that of the directors and shareholders!

Success Stories


“Here is my testimonial – I would like to thank you for all your help this year. It has been much appreciated. The speed you deal with my queries and problems is quite remarkable. Under your guidance, I have found the transition to becoming a limited company most enjoyable and informative.

Thanks again “

Sam Taylor

NON-RES Testimonial

“I would just like to take the opportunity to say thanks for the aftercare given by Whittaker staff and recently Claire Haddon.

As an ex-non-resident and former customer, Whittaker & Co completed my tax return for this year. They also provided the details to pay online and or wait for HMRC to send the bill. Having waited I tried to use the HMRC link supplied by yourselves to find it didn’t work. The support for resolving the issues has been first class as was the service when I was a non-resident.

I have returned to work with military types and the experiences and professional attitude I have had from Whittaker & Co has been first class and will continue to recommend the company to others leaving the services and seeking non-residency accountant support.”

MARITIME Testimonials

“Thanks very much for all that and everything else you have done for me over the last 4 years.
I’m not sure you will remember but I met you at the Ruwi in Muscat where I gave you my GMRS contract in person. From that point on I have been so pleased with everything that GMRS and Whittaker & Co have done for me. There hasn’t been one issue and everything ran so smoothly. Hence the reason that absolutely everyone I met while doing maritime; I insisted that it was the only way to go and I know for a fact that the majority did so. Not just for Ambrey Risk but while in hotels and transfer vessels speaking to many others too.
For a relatively small fee having all the admin taken care of is such a weight off your mind…”

Matt Turner


“I decided from the start to enrol with Whittaker & Co back in July 2011 after being recommended to use them by a work colleague and good friend as they specialise in security personnel offshore with regards to SED & Non-Res issues & taxes etc. I have received an exceptionally high service from Whittaker & Co since the word go and I have a great relationship with my account manager Jane Haddon who is extremely efficient and professional and keeps me informed of my days, invoices and anything that I need to know. She and the team are always there at the end of the phone, reply to emails promptly and take time to explain any queries that may arise therefore I would definitely recommend Whittaker & Co.’s services to anyone that is going into the maritime/CP industry not only for their professionalism & confidentiality but the friendly, polite & obliging staff they have working for them. They also have a member of staff working overseas (maritime) so there is a chance you can speak to her face to face if you have any queries while overseas.

Thank you for your continuous hard work, much appreciated as always.”


MARITIME Testimonial

“I have been in the Maritime world for over 2 years and joined Whittaker & Co from the start; through word of mouth from the lads.

Having met Claire Haddon personally abroad and from day one she has helped with all my inquiries. She provided me with a customer care second to none. Immediate replies on any queries and confirmations of documents received.

I would recommend Whittaker & Co to any Maritime personnel joining this industry, as the service given is 100%, 365 days of the year.”

MARITIME Testimonial

“I have been in the Maritime industry for 12 months following a successful 22-year career in the Royal Marines. Utilising Whittaker & Co for the whole period, colleagues advised me at the start to choose Whittaker & Co and I have nothing but high compliments towards them. They answer all my questions and reply to all my emails promptly, they also go out of their way to send a representative, to talk to maritime teams about the complexities of tax and how to achieve SED.

Ian Nisbet-Mole

NON-RES Testimonial

I can’t speak highly enough of the service and help I’ve received. I would specifically like to praise Steph Davies who has guided me through the minefield – HMRC and non-residency.

This is not a simple subject and she has been exceptionally helpful in resolving things for me; and explaining them to me in simple to understand terms. Phones calls are always answered and emails are replied to promptly despite a difference in time zones”.

Jon Tipper

NON-RES Testimonial

“It was a simple decision to make choosing Whitaker & Co after hearing some really good feedback from other customers. I left the military in 2011 and decided to pursue a career in close protection. The switch from military to civilian life left me with a lot of questions and paperwork, forms etc. to fill out but with Whitaker & Co.’s help, this transition proved effortless. As a result, it also gives me great piece of mind knowing that I don’t have to worry about tax days etc.

I would recommend Whitaker & Co without question due to the fact that the staff are very friendly and approachable and highly astute.”

Richard Daniels

CSA Testimonial

“I would like to thank Jane Haddon and Whittaker and Co for taking on my CSA case. They showed complete dedication and professionalism; through what I thought was going to be a negative outcome and a very bumpy rough journey. I can honestly say that I could not have dealt with this on my own. Constant calls and emails from the CSA adding more and more pressure on me. And I have enough to deal with working in a Hostile country.
For a one-off payment they stated to me they will not finish the case until they get a positive result. And true to their word a positive result was reached, CASE CLOSED! It couldn’t have been any better, consequently; I have recommended your services in this matter and also dealing with the tax side to many people.”
