David leads ForrestBrown’s London office, providing advice on all aspects of R&D tax reliefs, with a particular focus on supporting large, complex and global businesses. Through a personal, hands-on approach, David ensures companies benefit from their investment in innovation by securing the government incentives they are entitled to.

Starting his career as a software engineer with a FTSE100 financial information provider, David spent nearly 20 years in IT, designing and developing global platforms and leading international teams within ‘blue chip’ organisations. Subsequently, David helped establish EY’s R&D tax team before joining Deloitte as Innovation Tax Director. Most recently as Senior Director at Alvarez and Marsal, David established a new team, building a client base of listed and private companies across multiple sectors.

David has worked on some of the UK’s largest R&D tax relief claims across sectors including software, media, telecoms and financial services. He develops bespoke methodologies tailored to organisations’ needs, using his technical knowledge, project experience and communication skills to engage all stakeholders. David has built a strong working relationship with HMRC in the process, contributing to various committees and consultations.

Combining an engineering background with a wealth of experience in professional services, David is well placed to support the delivery of robust and efficient R&D tax relief claims for even the most complex companies and projects.

David is committed to building strong client relationships at a time when trends to automation and offshoring risk eroding service levels of other providers.
