Dr Peter Clayton
CMC CMgr FCMI FIC Excel Consultant efficiency automation and training


  • I’ve been doing Excel training since 1998 in both classroom settings and virtually to businesses.
  • I train intermediate and advanced users 1-to-1 or in small groups of up to 2 or 3 managers so they can learn at an accelerated speed.
  • I have been using Excel intensively for over two decades to run complex operations across the world, specialising in spreadsheets that analyse data quickly, improve business decisions and automating repetitive tasks.
  • I bring a wealth of personal experience as a manager and consultant on operational planning and budgeting in addition to Excel consulting and working on over 1,900+ Excel projects for over 700 organisations.

We have Excel competent people within the business but far, far from Peter’s level, his knowledge and passion is exceptional in this particular subject. Peter has implemented functionality we never thought was possible.

Excel training & coaching on real life projects

I run training & coaching for intermediate and advanced users of Excel such as managers who already know how the basics and want to make more powerful use of it. This might be generally or for a specific project. Training of many senior managers and directors in the UK and around the world in Excel to maximise their efficiency and effectiveness.

I am happy to run any form of refresher, bespoke and/or customised Excel training courses;

Training can either be done remotely online or in-person onsite, and on live projects too, and so providing the training that people need at the time they need it.

I can provide instant training on single formulas or single issues using Skype/Teams/Zoom as I charge per hour so however long it takes for you to pick it up is how much it costs.

I have run intermediate and advanced Excel training for large and small companies including:
