About The MGroup

You may be wondering where The MGroup got its name? We were formerly Miell and Company based in Oxford and we were established in 1928. Over the years we have helped thousands of businesses, including many of the most successful, to thrive in Oxfordshire and beyond. In 2012 we expanded and established a Witney office when we acquired Petersons.

Clients like working with us because of the efficient and friendly approach of our team. The picture taken above was some of our team at a recent company social event !

The Partners are focused on supporting clients proactively and will directly guide them through any process; offering advice not only at the start but also during and after the implementation stage. Our aim is to fully understand all your business needs and match these with the skillsets of our team.

In response to client needs, over the years we have developed four services areas:

For clients this means that they have access to experts for all their personal and business accounting needs. You will see the full range of services here and that we also offer specialist support services such as forensic accounting, charities, property and agricultural accounting too!

It is the personal attention by Partners coupled with access to our approachable experts, who cooperate across all service areas, which clients value.

The MGroup plays an active role in supporting the local community.

This includes:

  • Sponsorship of Oxford United Football Club (‘The MGroup 1893 Club’) – some of our team are lifelong supporters, others have even been players! Click here.
  • Supporting and promoting the local business community through participation in events such as West Oxfordshire Business Awards – and we are proud to be sponsoring their ‘Employer of the Year Award’ for the second year running. Click here.
  • Active fundraising for two fabulous local charities SeeSaw and Special Effect including driving in the Twin Town Challenge. Last year we were dressed as Teenage Ninja Turtles. As David Cameron said at the 2016 WOBA launch event ‘who said accountants were boring?!’

We are efficient and friendly advisers and are always happy to advise you on any business matters.



“Without a doubt, I recommend speaking with The MGroup. They are very knowledgeable, very understanding, have a good feel for our business and accommodate us quickly when we need help. We frequently get approaches from other accountancy firms and I tell them that we have no need to look elsewhere as everything is catered for very efficiently by Peter Smith and his team. I couldn't fault them."

Peter MaceManaging Director, TT Concrete

“We have been working with The MGroup for over ten years and have formed an excellent working relationship where both parties enjoy the benefits of each other’s expertise. We have always found The MGroup’s staff to be professional, courteous and attentive and would not hesitate to recommend their services.”

R Rosser, Chief Executive The In Oxford Group

“Fortunately, when we were ready to expand our company to the UK we were referred to The MGroup. As a North America based enterprise we had little knowledge of UK business and tax matters. The MGroup helped us with everything from compliance and payroll regulations to establishing a banking relationship. The staff members are very responsive and we continue to rely on their support as our UK operations grow.”

Laurie Diaz, V.P. Corporate Controller, Yardi Systems

“Mark has given me excellent Corporate Finance advice and support for 3 years and I would thoroughly recommend him. He is very tenacious in finding suitable companies to acquire and then good at negotiating and putting deals together, including the all important funding. He is also very innovative in finding solutions to issues arising along the way.”

Mark Swaby is a Management Buy In client

“I used The MGroup for the first time to buy another Drainage Company to add services & coverage to my own. Mark and his team give a top rate service from start to end and we achieved the purchase within 5 months – good honest, knowledgeable advice from people who know their stuff.”

Paul Marshall, Unbloc

“The entire, sometimes daunting, process ran on rails from concept to completion thanks to the professionalism of The MGroup.”

Stewart Betts, Director, Houlihan & Co Ltd

“We moved to The MGroup as our business had grown from a small to medium sized one and we needed more comprehensive support on all accountancy matters and detailed support with our SAGE systems. We have been really pleased with the service we have received from The MGroup and wouldn’t hesitate to recommend them to other businesses looking for an all round accountancy service.”

Sarah Steel, The Old Station Nursery Ltd
