Founded by Howard Walwyn in 2016, Prism-Clarity is a specialised freelance consultancy providing high-quality professional writing services to financial sector, professional and academic clients. It also provides customised training and mentoring services for educational bodies, corporate clients and individuals, helping people to write clear business English.

Howard is a Professional member of the Chartered Institute of Editing and Proofreading and a member of the Professional Copywriters Network.

Clients he has worked with since 2016 include the Bank of England, the Financial Conduct Authority, HSBC, City, University of London, the Institute of Operational Risk, Kepler Partners, Compliancy Services, FireDrake Consulting and VTB Capital. See here for testimonials from some of these clients.



Before that, Howard had 30 years of professional experience at blue-chip UK and international banks: the Bank of England, ANZ Investment Bank, Mitsubishi UFJ Group, Bank of America Merrill Lynch, VTB Capital and J.P. Morgan. During his corporate career he performed mainly regulatory, risk and governance roles, drafting and editing complex technical documents for C-Suite, Board and regulatory audiences.

This front-line experience has given him unparalleled insight into the needs of regulators, boards, management and the public for transparent, sustainable documentation on a wide range of financial sector topics.

His main specialism is financial regulation, risk and governance, where demand for high-quality sustainable documentation is high. He has worked on internal model documents, Basel I, II, 2.5 and III, the Fundamental Review of the Trading Book, CAD1 and CAD2 (CRR) applications, ICAAP, risk appetite, (reverse) stress testing, recovery and resolution, risk reporting including limit frameworks, risk policy, new products, and business strategy documents.

Earlier in his career he developed his writing skills at the Bank of England, writing customised correspondence with stakeholders, supervisory documents on banks and other financial institutions, and internal briefings and newsletters on international financial market and regulatory developments.


Supported by his university degrees in English Language & Literature (BA Hons, Newcastle upon Tyne) and Economics (MSc, London), Howard aims for the highest possible standard of English in a strong, clear writing style.

He also specialises in working with non-native English writers and ‘quantitative’ writers who need to convey complex material, but need help conveying it in clear English.



Howard lives and works in Hertfordshire, UK. He is married with two daughters, two stepdaughters and three grandchildren. His personal interests include choral singing, a wide range of sports, music, films and TV shows, gardening and natural history. He also volunteers for a nationwide charity.
