Having not been aware of the Industrial Buildings Allowances we could claim having recently purchased new industrial units four our injection moulding company Plastic Engineering Solutions (PES) in Wiltshire. Graeme McGregor at Leyton took us through the process in a matter of a few weeks to a positive outcome. So much so that I have already recommended Leyton to another business associate and friend.

The right blend of scientific and technical expertise, financial acumen and collaborative working, underpinned by people skills sums up what makes Leyton stand out.

Sam and David made the process very easy. They were quick to respond and very helpful on assisting with the claim. We'd be happy to recommend them in the future and we look forward to working together in future years.

We've worked with Leyton now for a number years supporting our R&D claims and the team have made our experience as hassle free as possible.

We have used Leyton over several years for R&D claims and we have found them to be the leading advisory firm in this area. They took the time to understand in detail how our business operates and where there is scope for R&D claims to be made. Their process is meticiculous but efficient, ensuring every detail is covered. Hind and Jack are exceptionally knowledgeable and professional and provide excellent support througout all stages of the process. I would highly recommend them and Leyton if you need any assistance on R&D claims.

Fantastic R&D support as usual from Jessica, Robert & the team on our 2024 submission. As always - ready to assist, quick response, knowledgeable and helpful. Going above and beyond.

We haved worked with Leyton for over 4 years now assisting with our R&D claim which can be a fraught p and time consuming process for an Architects practice however Leyton take all our information verbally and create our report from this. A simple accounts forms is completed by us and takes a couple of hours and we then liaise with any queries that arise and the report is ready to submit to HMRC. Excellent service

Leyton are a knowledgeable and professional R&D tax reclaim specialist firm who have supported Oscar Mayer for a number of years.
Great service from Waleed and Kenza and the whole team to guide us through the process and ensure accurate submissions could be made as part of our wider CT returns. Thank-you.
I hope we can do business again in the near future when the commercial need re-arises.

In past years the R&D claim process has been complex and confusing at times causing frustration. This year the technical and cost team at Leyton have been outstanding, they have explained the process clearly, had patience in breaking down the information we needed to provide and it's been a truly painless process!

Wonderful experience!! Knowledgeable team, tailored service to our circumstance helped us to submit our R&D tax credit claim in a timely and professional manner.

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’ve had an outstanding experience working with Leytons. From start to finish, the level of personal support and attention has been exceptional. The team made the entire process feel efficient and streamlined, removing the usual friction and complexity.

What really stood out was their tremendous insight—especially impressive given the relatively short length of our briefing meetings. They not only grasped the nuances of our work quickly but also added real value by identifying areas in our accounts that could be improved to better align with the tax credits claim.

Overall, this has been an absolutely stellar service—professional, insightful, and genuinely supportive. Highly recommended.

Regularly, about twice a year, I get a cold call from Leyton. This is despite me telling them every time that I am not interested, we already have an R&D tax adviser and to remove my contact details from their system. Never happens, they don't listen and I think this pushy sales approach probably gives an indication into the kind of company they are and the service they provide. The negative reviews left on Trustpilot also give an indication into the pushy and cash grab nature of their business practices.

This was the first time we'd used Leyton. Having found the current claims process increasingly difficult to navigate we were looking for advisors who could make it all work. The Leyton team could not have been more helpful and essentially took all the pain of every step in the process away from us. We will certainly use them again and have no hesitation in recommending them to other potential users.

We've used Leyton for several years to help us with our claims for R&D tax credits. Their team has built up a good knowledge of our company and the projects we work on and the whole process runs smoothly from start to finish. I have no hesitation in recommending them.

A fantastic team of knowledgeable ,polite and enthusiastic staff made the whole process very comfortable and stressfree.
