Simon's love of numbers and helping people has shaped his 20-year career in finance. After qualifying as a chartered accountant in 2007, he worked with KPMG in Edinburgh, gaining experience with businesses of all shapes and sizes.

What our clients say
When our charity's revenue increased to a level that required its annual return to be independently audited, we embarked on a search to identify a suitable firm. Simon Maughan & Co came highly recommended, so we decided to engage with them. We have never looked back.
Simon's professionalism and reliability make working with him a pleasure. I highly recommend Simon for anyone looking for a trustworthy and supportive accountant.
