Andrew Greenwell, Chartered Accountant
The person behind it

Andrew Greenwell
ACA (ICAEW) · MBA · Founder

I started Insights because I wanted to build the kind of accountancy I'd have wanted as a business owner — one that's proactive, straight-talking, and genuinely invested in your success. No call centres, no juniors, no January-only relationships.

Before Insights, I built and advised companies, backed early-stage startups, and spent time understanding what growing businesses actually need from their finances. That experience shapes everything — from how I structure your accounts to the strategic conversations we have along the way.

And Insights AI takes it further — your own analytics layer connected to your live business data, giving you answers whenever you need them. The kind of financial intelligence that used to require a full-time Finance Director.

We switched from a high-street accountant and the difference is night and day. Proactive advice, clear communication, and we actually understand our numbers now.

Switching to Insights saved us thousands in our first year. The salary and dividend planning alone paid for the fees many times over.

We're selective. Here's why that benefits you.

Do you qualify?

We work with a carefully chosen group of businesses. Not because we're precious — because it means every client gets Andrew's full attention, not a junior and a template.

You run a limited company — or you're about to. Ideally with employees, payroll, and real accounting complexity.
You want to understand your numbers — not just file them. You care what the P&L says and what to do about it.
You value expertise over price — you've been burned by cheap before, or you'd simply rather get it done properly the first time.
You want to grow — not just survive tax season. You've got ambitions and you'd like someone in your corner who shares them.
You're open to doing things differently — cloud accounting, AI-powered insights, proactive advice. You're not looking for 1987.
Ticked most of those?
You're exactly who we work with.

Let's have a conversation. 30 minutes, free, no obligation. If we're not the right fit, we'll tell you honestly — and point you towards someone who is.
