Established in 1984 by the firm’s founder, Giles Brearley, Brearley & Co have grown from a single room to five buildings at their head office at Swinton, Mexborough and now have offices in Dinnington and Dodworth, Barnsley.

There are now five partners within the practice, each with their own specialist skills.

Continuing in Giles’ footsteps we pride ourselves in a strong involvement in the communities that we serve.

Great things in business are never done by one person. They’re done by a team of people. – Steve Jobs


Whilst we do all the usual compliance work well, we pride ourselves on the added value that we bring through our proactive advisory work.

Using our experience and wide network of trusted contacts we provide a comprehensive ‘one stop shop’ service to our clients, ensuring that they are looked after every step of the way.

Our team are expected to have an open, friendly and responsive approach, which our clients tell us that they do!


The company’s success owes much to our core approach, which has remained throughout;-

We recognise that the ingredients of a successful relationship are teamwork and close co-operation with our clients. This level of understanding is gained by listening to our clients, using this insight and our experience to deliver the best possible results for them.

A key objective of our team is to help you work on your business, not always in it – to stand back and take on the overall look at yourself and your business, something which is often difficult to do because of your closeness to it. Sometimes a fresh pair of eyes are needed to give an objective view and that is something that we excel at!
