Who checks the maps

Checked by a chartered accountant. Written for owners.

I'm Clive Angel. I've spent more than 30 years in finance, helping UK businesses grow, raise money and get their numbers right. Most finance guidance is written by accountants, for accountants. Route Maps are written for the people running the business. I check every map against the official rules before it goes live, and we re-check them every month.

Route Maps are general information, not personal advice. If your situation is tricky, talk to your accountant.
