Maurice has an excellent wealth of knowledge about tax, also his connections are exceptional. If he is not able to complete a project by himself he has a raft of experts to assist him with any particular task. One of the best thing he did for me was to raise funding for my company which is now on its way to becoming a fully licensed energy provider. He is always my first port of call when I need help for my business. I would recommend him 100% to any one.

Maurice has an extraordinary wealth of experience and sound advice in relation to all financial matters. I quite simply would not have been able to get the business off the ground without his support! Maurice is a key part of our business and I value his contribution as part of the team moving forward.

I have used the services of Hargreaves MacKenzie & Kelly and I am very pleased and satisfied with not only the service they have provided to me, but also the outcome that I have achieved. Since using Hargreaves MacKenzie & Kelly and using their system, which works perfectly with my accountant, I have paid a lot less tax and I have even received a tax rebate. I have greatly reduced my costs and my business is going from strength to strength. I can recommend Maurice and his team to anyone.
Thank you so much for all the help I have received.

Maurice and his team were invaluable in navigating what was a pretty tricky and somewhat unusual financial situation for us. The wealth of knowledge and expertise they tapped into was great. Having been shut down by solicitors, they found us a solution that not only financially beneficial but made our position going forward much more streamlined.
Thanks again for your help. Will be in touch shortly about what we need to do once the mortgage company have been in touch.
