About WOCO

We help small and medium sized businesses to claim the R&D tax credits they are entitled to, but so often fail to make the most of.

Starting the business in 2013, William O’Brien was struck by the number of businesses missing out on what is probably the most generous corporation tax allowance in the UK. With over 20 years’ experience as a scientist & engineer, plus corporate finance and SME board experience he is ideally placed to maximise R&D claims across a wide range of companies.

Working with businesses

Our focus is always on making the process simple and convenient, and we try to do as much of the claim for you as possible. We analyse costs, writing detailed reports for HMRC and work directly with your accountants to smooth the process of making a claim. We do like to meet face to face with you to conduct the R&D review, as this often helps us to spot areas of work that might qualify for a claim that had not previously been considered. We work hard to make the time you spend with us really count, and we are often told that the couple of hours spent in the review meeting were among the most productive in the entire year!

Working with accountants

Most accounting firms recognise the need for specialist expertise when putting R&D tax credit claims together, and our work is usually done in partnership with client’s existing accountants to allow them to offer a more comprehensive corporation taxation service.

We have developed good working relationships with accountants all over the UK, and we offer a generous fee sharing arrangement in recognition of the additional value obtained for our mutual clients by working together.
