About Horn & Co.

Jonathan Horn has over 10 years’ experience in accountancy. Starting as a trainee in a regional firm in 2008 he qualified as a Chartered Certified Accountant (ACCA) in 2014 before leaving to join another local firm where he qualified as a Chartered Tax Adviser (CTA) in 2017. He left this firm in 2019 to set up his own practice.

Jonathan specialises in small and medium size enterprises (SMEs) from a variety of different industries and has a particular interest in assisting them with not only with their compliance needs but also in providing sound business and taxation advice to help them grow their business.

As a small but highly qualified practice we aim to provide you with the capabilities of a larger firm but with the cost and service provided by a smaller firm. 

We are regulated by both the ACCA and CIOT and are fully insured.
