“I just wanted to let you know that you all do a really good job for Frontier and that we are very pleased that we have been working together for over 20 years now. You have always been professional, approachable and friendly.”

Jamie Godsave – Managing Director
Endersham Cleaning Services

“Endersham is a very successful, privately owned business that has grown significantly over the years. We felt that our professional services requirements had also changed in line with this growth. We switched accountants and business advisors to Simmons Gainsford, who we believe had the experience and expertise that we required. Although we have only been working with SG for a little over a year, it feels a lot longer. This is a positive reflection of the time and effort they have put in to the relationship, to ensure a smooth transition and to understand our business and the motivation and goals of the owners of the business. We now have the right financial systems and structure in place to support our continued growth and receive regular management information that allows us to make important business decisions. We have more accountability now on both sides, and their advice has been particularly helpful when it comes to the use of new technology and making improvements to business process. I’m confident that we’ve made the right choice with Simmons Gainsford and look forward to working with them as a long-term business partner.”

Linda Yi, Financial Controller
BenQ UK Limited

"Simmons Gainsford have been our trusted advisors since our incorporation in 1997, and their support has been integral to our success. They handle every aspect of our financial and compliance needs, including accounts preparation, audit, corporation tax compliance, payroll, and VAT. Their comprehensive approach gives us peace of mind, knowing that every detail is managed with precision and care. In the past, they’ve also expertly guided us through HMRC’s complex periodic audit, ensuring we navigated any challenges smoothly. The team’s dedication and in-depth knowledge make Simmons Gainsford an essential part of our business operations. We couldn’t recommend them more highly.”
