Great service from the team at Leyton

Hi Ainslie, thank you for your kind feedback! We're pleased to hear you had such a positive experience working with us.
Leyton Delivered — Quickly and Brilliantly
We recently worked with Leyton on our RDEC claim and were extremely impressed with the experience from start to finish. The team managed to turn the project around incredibly quickly, demonstrating a deep understanding of both the technical and financial aspects involved.
They handled our technical team — who were initially a little reluctant to engage — with real professionalism and clarity, quickly building trust and drawing out the necessary detail without disruption.
Thanks to their expertise, our final claim value was significantly higher than in previous years, and the entire process was remarkably efficient. After just a 1.5-hour session, Leyton produced a comprehensive report and fully consolidated costs, all of which required no amendments.
We wouldn’t hesitate to recommend Leyton for anyone looking for efficient, insightful, and value-adding R&D tax support; with particular mention to Alex, Louis, Marco, Rikhil and team.

We have enjoyed working with Robert and his team for many years now. They make the RDEC claim process as frictionless as possible for our business and are always available to provide additional support to our tax and accounting teams as necessary. I would have no hesitation in recommending them.

Happy with the Service and Charges.
We've worked with Leyton's for several years to submit R&D claims. Each year we have received a small (in comparison to our turnover) credit towards our CT bill. Whilst these levels of income won't transform our business they are welcome, and not something we would ever get round to doing ourselves.
Leytons are clear about what they will charge you, when they will charge you, and when they expect payment, we've no issue with them in that regard (or any other).

Excellent Service
We had excellent support developing our R&D tax credit claim from Omar Abouelazz and Wissal Hajjaj. As in previous years, they were clearly willing to go above and beyond to facilitate the process, with clear explanations and incredibly rapid responses. We fully intend to continue working with Leyton based on these experiences.
