What our clients have to say

It was a pleasure working with the guys at Bonham & Brook, especially considering that, with the wealth of knowledge backed up with the expertise of an ex HMRC officer, we had confidence going ahead with a claim for the first time. After successfully receiving a substantial refund, we would not hesitate doing another claim and, it goes without saying, Bonham & Brook will be our preferred partners going forward. Thank you, again.

Chris Strik

Managing Director

We worked with the team at Bonham & Brook on the R&D claim that we were unaware of. To our surprise they made the whole process seamless and we received our refund from HMRC. We will definitely be using B&B again for our R&D claim to help us grow our business.

At first I believed that R&D tax credits were a little too good to be true or that my company would not be applicable. Jenson, Hannad and the team's expertise and experience reassured and guided me through the process. I had to put in approx. 1 - 2 hours work and they did the rest of the application. The first time we worked together they were able to claim for the previous 2 years, so we received a bumper double rebate. This money has helped us grow the business by having the cash to grow the team and increase our marketing budget. My business has grown thanks to their work, so I am eternally grateful.
