About Simmons Gainsford

Our size and ethos means that we have a natural empathy with entrepreneurs, start-ups and growing businesses. Our client base is diverse and includes media, entertainment, retail, property, hospitality, manufacturing, recruitment, lawyers and charities. Our remit is to solve problems and create solutions so the compliance work – such as audits and tax returns – is complemented by creative business and strategic planning.

We have grown steadily over the years but not to an extent that we don’t know one another. We’re fortunate in that we have the following teams: Audit & Accounts, Corporate, Personal and Indirect Tax, Bookkeeping, Payroll, IT, HR and Internal Accounts so we can all work together to help businesses as we offer a wide range of advice and solutions.

We enjoy what we do, we love being challenged and we are always striving to improve. We’re not going to deny that it can be a demanding environment at times – but that’s a great one in which to learn and grow stronger in our knowledge – and we don’t have a late hours’ culture.

Our Partners and Managers are approachable, incredibly supportive and dedicated to providing an individual career and personal development path for all our staff. Many of them began as trainees themselves so they understand the journey ahead for our new trainees as they mentor them.

We offer CPD training throughout the year as it’s important that our clients receive the most up to date and relevant advice, and our staff are continuously learning so they are empowered by their knowledge. There is always the opportunity for individuals to suggest any ad hoc courses.

We are a sociable bunch too! As well as our annual firm-wide seasonal events, we have a social club who think of even more innovative ways to have fun throughout the year.

We also like to keep everyone updated – and share ideas – by having regular team briefings, employee focus groups and staff meetings
