Perfect for contracting, great support

I have been contracting with my wife under a LTD for 2 years. Nixon Williams have been of great help to set up and run the company.

– They have a very reactive and efficient service.
– Their online accounting software vantage is simplified yet instinctive.
– They have a lot of resources to help you take on your director’s role

Big shout out to Gary, very knowledgeable, who gave me one of the best customer service I ever experienced.

I recommend for any contractor that operates in the UK.

Nixon Williams review

I was referred to Nixon Williams by a friend who uses them. They have been my accountants for 9 years, easy to do business with, answer any queries I have. Would definitely recommend them.

Great Start with a non local agent.

Early days with these guys but – they ooze confidence so I am sure they will deliver.. Quick on the mark / on the ball. And kept pushing me when I’ve been busy which is exactly what i’m looking for.

I would rate more starts if I’m allowed to

I have been using Nixon Williams for almost 8 years until now. They are such a big help and trust me, I really mean it. As a small company director, I don’t want to spend too much time on bookkeeping, accounting and taxation and with Nixon Williams, they really help with EVERYTHING. I rarely need to spend more than one hour each month on the basic bookkeeping and they will take care for rest of it.

Anita Dinardo is the account manager I’m working with, she and her team are really professional and efficient, always respond quickly and answer my questions clearly and patiently. I would rate her and her team more stars if I’m allowed to.

Simple, no-nonsense accounting support

I’ve worked with Nixon Williams for around five years. They’ve made running a small business easy from an accounting perspective. Highly recommend their support for anyone running a relatively simple business who wants to just focus on their day job, not the books.

Over 10-Years with Nixon Williams

I have been using Nixon Williams for over 10-years since I started as a contractor in IT. My overall experience has been mainly positive.

My current accountant is Sulaiman. He deals with all my email or phone queries on a regularly basis when needed.

My 10-years overall experience with Nixon Williams has been mostly straight forward and easy to deal with.
