About Kieron

Experience you can rely on,
support you can access

I'm Kieron McGahan — a CIMA-qualified accountant with over 30 years of commercial experience, based in Crawley, West Sussex — my practice base for over eight years, now serving clients across the UK.

I set up KG McGahan Consulting to provide the kind of accounting support I'd want myself: responsive, plain-speaking, and genuinely focused on the client. Clients get direct access to qualified expertise — responsive, reliable and focused on getting it right.

I work with a range of cloud accounting tools — including Xero, FreeAgent and QuickBooks — to keep things efficient and accessible, and I stay on top of Making Tax Digital so you don't have to worry about compliance.

What an amazing chap (full stop!) — I am so glad that I found him via Google search. It has been an absolute pleasure having Kieron handle ALL our financials for my small owner-operator business. If you just started a small business and don't know where to go, call Kieron, he can help you. I would not have managed to navigate through the HMRC gateway system without his expertise. I am a very happy customer and would recommend Kieron to anyone.
