Simmons Gainsford

First established in 1948, Simmons Gainsford Group is a multi-disciplinary firm of chartered accountants and business advisors. Our main office is in Central London, with additional offices in Sussex, Gibraltar, and Poland. Our size, structure, and resources enable us to provide the full range of services and technical expertise, but with the personal touch that comes from a high level of partner engagement. In 2023, Simmons Gainsford became part of Sumer – a collaboration of renowned regional accountancy practices with a shared vision to deliver high quality professional services locally supported by national expertise. Our core client group consists of successful, privately-owned businesses ranging from start-ups to businesses with turnover in excess of £500m. Over the years we have helped many of these clients grow nationally and internationally. We combine our love of problem-solving and creating solutions for our clients, with practical business advice and strategic planning, regardless of where they are in their business lifecycle. A key focus of our business is inward investment to the UK, especially from the emerging Asian and Eastern European markets. Our multilingual partners and team members have strong links in these jurisdictions and are ideally placed to help businesses seeking to trade in and with the UK. We also have extensive experience in dealing with the personal taxation affairs of foreign nationals residing or working in the UK. And with our Gibraltar office, we are perfectly placed to advise UK nationals looking to establish residence in Gibraltar. Beyond accountancy, audit, and tax, we regularly advise clients on broader business requirements. Within the Simmons Gainsford group, we have several businesses that provide specialist expertise in the areas of Capital Allowances, Credit Management, Financial Services, and Procurement.
