We are a full-service accountancy firm working with people, not numbers. Combining compliance, day-to-day support and business strategy to help you flourish inside and outside of your business.

As business owners ourselves, we understand many of the challenges and obstacles you face, especially when it comes to things like finances and tax. Most importantly, we have the knowledge and expertise to help with the more exciting and progressive areas too.

We work as an extension of your business, combining well-organised accounting support with practical advice when you need it. By understanding your circumstances and plans, we can help you meet your responsibilities today and make informed decisions about what comes next.

Whatever your ambitions, inside and outside your business, we provide support, insight and practical advice to help you work towards them—with your family’s security, balance and opportunities in mind.

The human face of accountancy, that’s how I’d describe Simon. If you’re looking for an accountant who has the time to treat you like an individual, not a number, I can highly recommend working with him. He has helped me get to grips with elements of handling my accounts that I didn’t know existed making things streamlined and user friendly. His approach is friendly and he is very generous with his accountancy knowledge

 – Sarah, Sarah Gatford Ltd

If you want an approachable Accountant who really gets to know you and your business and knows his stuff then Simon is the go to person. Simon is our Accountant for a not for profit networking group, and I find Simon very pro-active in providing advice that can be acted on (as opposed to finding something out after its been implemented!). He is a great guy and gives him time freely to support other businesses with their growth.

 – Sarah, Networking Group

I hold Simon Thacker in the highest of respects. He has an excellent grasp of current technology with outstanding accountancy skills. Simon is incredibly easy to work alongside and I highly recommend him to anyone looking for a professional and reliable service.

– Sophie, Sales and Marketing

Simon is the accountant that everyone one needs. He manages to unravel the mystery of the numbers so that they make sense in a non-complicated way. Simon is an excellent communicator, a real support and an asset to any business. If you need a solution to better manage your finances then don’t hesitate to contact Simon.

– Vicky, Fox Business Support

I highly recommend Simon if you need expert, honest, up-to-date accountancy advice, delivered in a timely way by someone who wants to understand your business. Simon has successfully set up & converted our accounts over to XERO. I can honestly say it was such a simple process-his knowledge & helpfulness speak for themselves!.

– Lorna, Jolly Back

Simon provided us with a fantastic service as a young fledgling business; most importantly with sound advice during the more difficult times and I wouldn’t hesitate to recommend his expertise and knowledge to my friends and associates

 – Richard, Purple Harry

 

Simon is that unicorn that we’ve all been looking for – anengaged and proactive accountant. He’s sorted my accounts,sorted my Xero, sorted my bookkeeping, sorted my gocardlessand been invaluable with advice on all my accountancy and taxissues.

We have worked with the Greystone team for many years. Simon is currently our accountant and virtual FD. His advice and support have helped us to go from strength-to-strength. All of our staff see him as another team member, an integral part of what we do as an organisation.

    I have recently moved over my accountancy to Greystone Advisory and the process has been professional and extremely well managed.  The communication is second to none.  I feel that there is a genuine desire to understand my business and also to help me manage and achieve financial goals. I would not hesitate to recommend and I am looking forward to moving ahead with them.

    Simon and his team have guided me though a difficult personal and business situation which became drawn out and messy. Remaining professional at all times, he made the experience very smooth, which helped me deal with this. Would definitely recommend him and his team.
