I write and edit content for finance, business and academic clients, using clear business English.

After 30 years of finance industry experience I retrained as a professional editor, bridging the gap between finance and language.

I am also a finance copywriter, technical documentation author and tutor/mentor in business writing.

Until March 2020 I was a visiting lecturer in business writing at City, University of London, and now run customised writing training programmes, including online.

I use my analytical editorial skills to do development editing and manuscript reviews for independent fiction authors.

Versatile, meticulous, expert, unfailingly professional and reliable.


High-quality, transparent, sustainable documents, customised to your needs and written in clear professional English

For editing jobs, please include a sample if you have one. This helps me to assess the complexity of the job and give you a realistic quote.

All prices depend on the type of job, complexity and turnaround time. I quote by the day, hour, or thousand words depending on the job.
