Now owned by Frieda Howlett, HDAS (Howlett Dalzell Accountancy Services), has had various changes to the business name and logo over the years. The practice has a long history, operating in Thames and has been trusted by locals, since 1959. 

Frieda has over 20 years of experience in the company, taking over the reins in 2014 when previous owner, Geoff Dalzell decided after 50 years, more personal time was well overdue. Geoff still helps on a consultancy and sub-contractor basis, so hasn’t quite lost his interest in accountancy and the practice.

Frieda is taking her team into new places with the move to MYOB whilst continuing the honest, transparent friendly approach the company has long been known for. 

Thames is in exciting stage of re-birth as a heritage destination, tourism, engineering, agriculture, aquaculture and artisans. HDAS is ready to help these businesses and also help advise you if you want to start a new business.

So whether you're a builder, or a craft beer brewer - we're here to help!

Geoff was the previous owner of the practice and decided to ‘semi’ retire so that he could spend more time with his wife and enjoy life out of the fast lane.
