About Us
The finance partner ambitious owners call first.
Mercian is the chartered, partner-led finance team for ambitious UK businesses, landlords and individuals — embedded in the day-to-day, and at the table when the decisions matter. Senior-led. Plain English. No corporate runaround.
Why we work the way we do
Most accountants talk about being “different” and then look identical: hourly billing, juniors doing the work, a partner you only see once a year. That set-up was designed for the firm, not for clients.
We were built the other way around. Every client gets a named, qualified accountant they can call without watching the clock. Every engagement has a fixed price agreed up front — no surprise bills in February. We work in Xero rather than offering a confusing menu of platforms, because depth beats breadth. And we say it in plain English because tax is hard enough already.
The result is a firm that’s straightforward to deal with, predictable to pay, and a bit more useful than a once-a-year visit to the accounts department.
Principles, not slogans
The promises behind every fixed-fee engagement we take on.
Clarity beats jargon
If we can’t explain it in a sentence you’d repeat to a friend, we haven’t explained it. We rewrite our own emails.
Cloud beats spreadsheets
Real-time numbers, real-time advice. Xero everywhere, Apron for receipts, secure portals for everything else.
Senior people, every job
Your accountant is a qualified senior — not a junior with a checklist. Every return gets a senior review before it goes near HMRC.
Fixed fees, full stop
One price agreed up front. Call as often as you need. No “well, that took 12 minutes” surprise lines on the invoice.
