Excellent service

I have used Nixon Williams since 2010 when they helped set up a limited company so I could go contracting. They have always provided excellent service. My accountant, Connor Jordan, has recently helped with various issues and queries from me regarding a range of topics such as IR35.

In safe hands

I’d like to say a big thank you to Chris Orford for being amazingly supportive, always going the extra mile to be helpful and guiding me through the past few years of running my Ltd company. Both Chris and the Nixon Williams team have been the assurance and peace of mind i’ve needed so i didn’t ever need to be concerned about my business as they had it covered.

Fantastic Accountancy Firm

Nixon Williams are one of the best accountants and professional in supporting me as a contractor. I would recommend anyone looking to use a limited company to engage the team and Nixon Williams to setup and guide you through a maze of tax appliances that have to be completed with HMRC.
