What our clients say

Im self employed and started working in the UK in November 2015. I wasn’t sure what i had to do regarding my taxes and Austen was recommended to me. I approached him 2 days before the tax deadline in a bit of a state and he took the time to explain the process, helped me register for tax, arrange an extension on my tax return and then completed and filed my tax return for me.

Being a sole trader is stressful enough without the hassle of struggling through the annual self-assessment, but thankfully SBM Accountancy came to my rescue! Austen was really helpful and gave great advice, and it was completed quickly and painlessly. Thanks for your help!

Holly Lewis Design & Marketing

We have worked with Austen and SBM Accountancy for around 2-3 years now, and have been extremely happy with his hands on approach and the support that he continues to provide. Working with him in this time, he has helped to provide strategy that has supported amazing growth in our business.

When starting up a small business, it can be very daunting. With SBM Accountancy they really did hold our hand through the process.

Richmond Osteopaths

After years with my old accountant, I ended up paying a lot of tax. I was told to speak to Austen at SBM Accountancy. I have to admit, I was surprised at how efficiently he dealt with my tax affairs. He helped to show me that i had not been claiming my expenses correctly and that i had overpaid tax previously. As a result i ended up with a nice tax refund this time.

Who knew that accountants can actually help.
