JPL was established in 2004 when husband and wife team Jon and Hazel Lishak took their first business risk – establishing a successful accountancy practice on their own, with the support of a handful of key clients. Since then, the business has evolved with JPL acquiring more than just accountancy experience along the way. The client portfolio has grown, mainly by referrals, and the business is set for continued growth in the future.

Our clients operate in a wide range of industries including construction, retail, pharmaceutical, wholesale and distribution, property, leisure, entertainment and travel. We act for a large number of professionals and self-employed individuals and not-for-profit organisations.
