Why Lumi

Why Hampshire businesses choose Lumi Accountancy

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, Hampshire's plain-English accountants, 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 take the financial burden off your plate entirely — handling all the compliance, tax and reporting — so you can focus on running your business. And rather than just filing your numbers, we make sure you understand them. You'll always know how your business is performing, what's coming next, and what you should be doing about it.

"Professional accountancy, delivered with a bit more personality."
— Chris Sullivan, Founder

What Clients Say

Don't just take our word for it

★★★★★

"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."

About
Chris Sullivan with Chip and Link, his two dachshunds

Chris with Chip & Link — the unofficial Lumi mascots.

The person behind Lumi

Hi, I'm Chris.

I started Lumi because I genuinely believe accountancy should feel less like a chore and more like having someone in your corner who you can ask questions without judgement, with no topics off limits.

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!
