COVID-19 update (September 2020)

We have now resumed our normal office opening hours of 9am to 5pm but with the majority of staff still working from home.


Clients can now drop off books and records throughout our normal opening hours, but it is important that you call us ahead of your arrival, to enable us to ensure the appropriate social distancing precautions are adhered to.  Client meetings are strictly by appointment only, you can arrange an appointment either by phone or email.


If you do visit our offices, please observe all signage in relation to the health and safety precautions in place.


You will understand that we are still experiencing a huge volume of requests for assistance at this unprecedented time.  We will answer all calls and emails as soon as we can but would like to apologise if it takes us longer than normal to respond.

"We have been a client of O’Brien & Partners for nearly twenty years. They were with us through the initial re-structure of our business and have been working with us ever since. We feel that as we have grown, they have too. Lewis has a competent team and Cath (Accounts and Audit Manager) has always provided a responsive and consistent service.

Over the years we’ve got to know the team well and it is always a pleasure working with them. The fact we have a direct relationship with the partners has been invaluable to us. We like to know that we can pick up the phone and speak directly to Lewis, Gareth or Mark whenever we need to."
