“We cannot praise the team highly enough for their professionalism, diligence and customer care and would certainly recommend them as the best choice to make a successful claim.”

Engineering Design Company, South Wales.

“Many thanks for your help at the end of last year.  We especially appreciate your dedication to ensure the claims made the deadline, at what was a very busy time for us.  I certainly agree that R&D claims are worthwhile and we will certainly want to make another claim.”

Engineering Company, West Wales.

“The team made the R&D Tax Credit simple and understandable and was clear about the process every step of the way.  They helped us get a successful outcome.”

Software Company, West Wales.

“We have been working with LimestoneGrey since they started. Their knowledge on R&D claims is exceptional and we have no hesitation in referring our clients to them.”

Advantage Accountancy & Advisory Ltd, Cardiff.

“Having experienced the preparation and submission of several R&D submissions in the past, I knew how onerous and time-consuming the process could be. I was only too pleased to meet with the team and be reassured that he would simplify the process and could provide advice and direction as to how the submission should be put together. We were happy with the size of the claim as it was larger than we anticipated, and due to the quality of the submission HMRC quickly processed the claim.”

Fintech Company, Cardiff

“Thank you LimestoneGrey. You guys have been extremely professional, patient and dedicated. I can’t wait to continue working together for the foreseeable future. Another year!!”

Software development company, Cardiff.
