Dr Peter Clayton
CMC CMgr FCMI FIC CMgr=Chartered Manager; FMCI=Fellow of the Chartered Management Institute; FIC=Fellow of the Institute of Consulting


I have worked on over 1,900 projects both large and small for over 700+ clients over the years. Not only do I specialise in using Excel but I have also managed significant IT projects and made business improvement assessments and recommendations so I can also provide a second opinion on how to make use of the results in your business and make suggestions on improvements from a business perspective.

It is my understanding of what the results are used for and their additional interpretations that will make my Excel work more meaningful and useful to you. I am a power user of Excel from managing real-life projects myself which allows me to act as an Excel consultant not just as an Excel trainer.

Excel Consultant Testimonials

“Peter created an excellent one page Excel Director KPI cockpit which has had a positive effect on CHH Board meetings. Visually we can see key information quickly and the subsequent discussions focus on the real issues. Peter’s knowledge in preparing the cockpit also saved a huge amount of time and effort – Many Thanks”
Tim Hughes, Managing Director, CHH Conex Limited

"Peter helped us overcome an Excel challenge turning software codes into an Excel task scheduler using calendar dates and times, which we initially thought was impossible. He also did it in super-fast time, in a way so easy, that anyone could operate it regardless of their Excel knowledge. It’s literally a 3 click process. The overall saving to the business (Software and administration hours) exceeds £10K p/a, however the fact that anyone can now operate this model is simply priceless."
Matt Lynn, Commercial Operations Business Analyst, AkzoNobel

"The work undertaken by Peter has greatly improved our risk management system by reducing man hours required to populate and also by guaranteeing accuracy by automating the system. The scope he executed was completed quickly and with no re-work."
Andy Sutherland, ABIS Projects

"We had been trying for over three years to find and commit the huge manual resource to our database development, a task we knew would increase our sales performance dramatically. After explaining our aims to Peter we managed to condense a year of manual spreadsheet work into a few hours automation and macro building via Excel which has meant we have freed up a member of our team full time. Peter's experience and knowledge are powerful tools which we would recommend you harness the power of for your own business."
Gemma Price, Superfood Market

"As a small business owner my time is in great demand; Peter’s work has enabled me to carry out some of my routine tasks in a fraction of the time it usually takes, enabling me to me to spend my time on more important matters. He has also created a piece of work that far exceeded my expectations, using his Excel experience to improve on my ideas. I’m delighted with his work and would heartily recommend him to others."
Charlotte Baldwin, Colour Your Garden

"I had a client with a jumbled up selection of spreadsheets containing almost 40,000 shoes and after spending the best part of a week editing the data so that it could be imported into a online store I decided a professional was needed. Peter's website stood out from the rest and gave me a good feeling. A quick email describing what I needed and a few back and forth additional emails resulted in my data being ready in just a few hours. I'd estimate that Peter has saved me 6 weeks or more of boring work. I'll be using Peter's service again for sure and would encourage anyone with a lot of products to import to give Peter a go as the cost was very reasonable."
Richard Jordan, Handcoded.co.uk

"I knew we could be doing more with our data, but wasn’t sure what was possible, and didn’t have time to investigate.  I have a good knowledge of Excel, but using Peter was absolutely money well spent. It wasn’t just that he was able to do things much quicker and more elegantly than I could, it was that he was very quick to grasp the issues, ask the right questions, so that the whole process was easy and quick.  We’re able to use our data much better now as a result."
Michael Mann, Head of Operations, Mathematics Mastery

"Peter easily achieved all the agreed outcomes with all stages fully completed and often exceeded; Peter consistently took initiative to promote the project and strengthen business aims and relationships.

Peter provided a seamless link to our sub-contractors in the UK and proved personally essential in framing internal expectations, providing additional value to elements of the proposal formerly covered by others, without friction.  Peter was a very popular and valuable member of our team.

Peter’s analytical knowledge and application of skills using such tools as MS Excel and other computer programs was extremely helpful.  His efforts, often in excess of expectations, to assist the whole team were immeasurable.

Peter sees problems very clearly and can quickly grasp complex issues, thinking swiftly through options and providing clear solutions.

All of Peter’s work is very well presented, clearly organised and critically evaluated at each stage, his use of written language is excellent and his ability to depict his solutions in graphic format are equally admirable.  In short he is a joy to work with and I would highly recommend his services to others."
Tim Washington, Managing Director, Walk Consulting Group

“I run a small charity which is undertaking a household survey in rural Kenya. I spent just under 90 minutes working with Peter and I know that his input has saved us at least 3 weeks of work in collecting and analysing our data. I’m fairly new to using Excel, but Peter pitched his advice at a level that I understood and left me feeling confident that I can implement the strategy he recommended”
Ben Skelton, DigDeep (Africa)

"Morgan's Historic & Classic Vehicle Events Yearbook is a directory containing more than 1000 events witha mailing list of 4000+ subscribers raising £250,000 for charity in just 11 years. The efficiency of the production, distribution and accounting processes is highly-dependent on a suite of Excel spreadsheets that have been developed and enhanced in close co-operation with Peter. We can now offer the best possible service to our subscribers, maximise the benefit to charitable causes and make the most productive use of our volunteers' time. Peter's ready understanding of our requirements, the inventiveness of his solutions and speed of response must surely be without equal."
Tony Raylor, Editor - Morgan's Yearbook, York Vikings Rotary Club (registered charity 1078432).

"Peter has been extremely helpful towards finding a solution for our reporting requirements. Even when the macro needed to be amended on numerous occasions, he was open to our suggestions and promptly implemented new fixes without delay."
Jane Tully, Head of Insight and Engagement, Money Advice Trust

“Thanks again for your excellent work. It seems to work well, so much so that I'm alarmed to realise just how much time I've been wasting doing this myself!”
James Benford



"Thanks again for your help, it made a huge difference to the efficiency of the data management on a complex project. Not only was your work to a very high standard technically but also the speed with which you cracked my problem was really appreciated."
Ken Scott, Senior Project Manager, Vision Consulting.

"Peter provided us with a great opportunity to transform our Human Capital Reporting capability.  He worked quickly and efficiently at identifying and understanding the business deliverables and also the technical challenges of our current offerings.  The result was a solution that is not only more sustainable but has literally saved us hundreds of man hours.  We now have an in house reporting capability which provides long term efficient and dynamic reporting from a complex set of systems which we did not previously think was possible.  Will definitely be recommending his business."
Amanda Childs, Divisional HR Business Partner, Siemens PLC

"What a fantastic service! Peter took complex data and made it into something that made sense, had visual impact and helped us to tell our story with clarity. Previously I have tried to do this myself but the benefits of using Peters service were speed and expertise. Great value for money."
Colin Middlemiss, Communications and Engagement Manager, Yorkshire Water

"Peter very quickly worked out our requirements and helped develop the logic and sequences needed to create the user-friendly decision-making tool we were looking for. I will be recommending his services to other departments."
Jamie Lawrence, Senior Sustainability Advisor, Kingfisher Group

"Peterís work on a major financial reporting project was essential to our organisationís drive to improve our services to members. Quite simply, we could not have done it without him. Peterís extensive technical abilities and fast turnaround re-established our confidence in the project and the final result found new options for improvements and efficiencies that paid for themselves many times over in the following months."
James Vrac, Executive Director, UHY International

The quality reports have been very well received by my colleagues who have commented how the professional presentation of the data will inform us all about our practice. Because of his efficiency Peter delivered the project at a cost well below what we had budgeted. He clearly has a wealth of experience and expertise and I would highly recommend him to anyone."
Stephen Wright, Consultant Anaesthetist, National Health Service, Newcastle

David Evans, Evans Accountants.

"We were looking to create a tool to capture and analyse raw data and present emerging media trends for multiple stakeholders.
