our ethos

As business owners, we understand that the factors that motivate and drive growth are as varied as the individuals who choose to build a business in the first place. That’s why we are focused on providing an individual approach to our clients, working closely alongside them to better understand their business needs and deliver a bespoke solution that supports capital growth for both businesses and individuals.

Sustainability for our gbac team, our clients and our community, is at the heart of everything we do. We welcome change, continually investing in and looking for new ways of working to remain as pro-active and efficient as possible for our clients in this ever evolving world.

We are proud to be an accredited ACCA training practice, to have achieved Gold Standard for Investors in People, and more recently we are on the road to become B-Corp accredited as well as working towards gold standard for Be Well at Work. These accreditations are not simply badges that we have collected but rather reflect our professional commitment to our gbac values.

We are honest, open, ethical, and fair, and what we do, we do well.

  • We are fortunate that gbac has been able to support us across the full range of financial services that we have required. As well as day to day support on payroll and our accountancy software leading to prompt and accurate financial reporting, we have benefited from tax planning advice from one of the partners. As well as providing these efficient and cost effective services it is a bonus to receive such friendly service from the whole team which makes us feel we are a valued client despite being a relatively small business.
