“Chris was brilliant. He helped me fix some messy VAT issues right at the start and has been incredibly responsive ever since. I really appreciated the useful advice on the next steps for my business. Proactive, professional, and highly recommended!”
“Lumi Accountancy has been great. I started my business recently. I spoke with half a dozen different accountants after my wife's bad experience with an accountant caused considerable issues. Lumi were the only accountancy that consistently provided me with timely responses to enquiries and questions enabling me to make effective business decisions quickly. They make completing accounts simple from an owner's perspective who needs to focus on running and growing the business.”
“Very detail-oriented, friendly and capable service. We are very grateful to Lumi for everything they do for us!”
“Chris has already made a great impact on the structure of our company bookkeeping and accounts. Really impressed.”
One chartered accountant. Not a team you never meet.
I'm Chris. I spent seven years in practice before starting Lumi at Abbey Mill in Winchester, and I built it around the thing owners told me they were missing: someone who knows their business, explains what the numbers mean, and picks up the phone.
No account managers, no juniors doing the work behind the scenes. You get me — and, some days, Chip and Link.
