Straight-talking.
Your numbers, finally making sense.
Personal, plain-English accountancy for companies just starting up to growing entities up to £10m turnover. Based in Winchester — without the stuffiness.

Let's be honest: most people find accounting a bit of a headache. Usually that's down to dense jargon and the feeling of being "just another number" in a giant database.
At Lumi, we do things differently. You'll always deal directly with a Chartered Accountant who actually knows your business. We explain things in plain English — no buzzwords, no waffle — and we're genuinely responsive when you need us.
We handle the technicalities. You focus on running your business.
"Professional accountancy, delivered with a bit more personality."
We explain your finances in terms you actually understand — no acronym-soup, no jargon for jargon's sake.
You speak to a Chartered Accountant — not a call centre, not a rotating door of juniors. We know your business.
Email support across all packages. Unlimited phone on Complete. We won't ghost you when deadlines loom.
We don't just file your accounts and disappear. We help you understand your numbers and use them to actually grow.
Every package includes a Xero subscription — our recommended software. Happy to support other platforms too. No hidden add-ons, no nasty surprises.
"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!"
Chris with Chip & Link — the unofficial Lumi mascots.
I started Lumi because I genuinely believe accountancy should feel less like a chore and more like having a knowledgeable mate in your corner — one who actually explains things rather than blinding you with jargon.
I've spent over 7 years in the industry, working across audit, accountancy, personal and corporate tax, and supporting businesses through acquisitions and sales. I love the variety — no two clients are the same, and I find that energising.
What I can't stand? The kind of accountant who files your return, takes their fee, and disappears until next year. That's not Lumi. We're here when you need us.
When I'm not waist-deep in spreadsheets, you'll find me walking Chip and Link (my two dachshunds), cheering on Southampton at St Mary's, or playing football — usually until I get injured!
Getting your finances right from day one is way easier than untangling them later. We help those starting up businesses through to established entities — with experience in dealing with both situations.
