About Aquium Ltd — Your Trusted Accountant in Kent
Aquium Ltd is a modern, client-focused accounting practice based in Kent, built on over 30 years of experience supporting small and medium-sized businesses across the UK. Formerly known as Sarah J White Accountancy, our new name reflects our continued growth — but our values, service quality, and personal approach remain exactly the same.
Our Story
I’m Sarah Wimble, Director of Aquium Ltd. My journey into accountancy began in 1990 after a career in banking. I joined a local practice as an Accounts Assistant, gaining hands-on experience while studying for my Association of Accounting Technicians (AAT) qualification, which I achieved in 1995.
Over two decades, I worked in respected one-partner and multi-partner practices across Kent, preparing accounts for a wide range of clients:
Sole traders
Partnerships
Small and medium-sized limited companies
Investment clients
Property portfolio and rental-income clients
This deep and diverse experience shaped my approach: clear, friendly, reliable, and always focused on helping clients understand their numbers and grow with confidence.
Our Mission
At Aquium Ltd, our goal is simple:
To make accounting easy, transparent, and stress-free for business owners.
We provide tailored support to entrepreneurs, start-ups, established companies, and individuals who want dependable, jargon-free accounting from someone who genuinely cares about their success.
Why Clients Choose Aquium
⭐ Personal, accessible service
I’m known for being approachable, down-to-earth, and easy to talk to. You’ll always deal directly with me, not a revolving door of staff.

From tax returns to compliance queries, I take the stress out of dealing with HM Revenue & Customs so you don’t have to.
⭐ Local knowledge, backed by modern tools
As a Kent-based accountant, I understand the needs of local businesses — and I combine this with up-to-date software and efficient digital processes.
