But my business doesn’t do research and development?!

A large amount of businesses that qualify for R&D tax credits fail to claim. A common reason for this is that businesses do not consider themselves to do any research and development. If your business is developing products, services or processes, you may qualify.

About ZLX

As R&D tax credits experts, we specialise in securing claims that are above the national average. Our success rate is also above national average.

It’s thanks to a refreshingly different approach, which we believe is unique among tax consultancies, and has enabled us to get great results.

Rather than being led by experienced accountants, our team is led by innovators who have real front line business engineering and R&D experience. We’re supported by highly skilled accounting professionals and we all share a forensic attention to detail and an eye for the opportunity.

This unique combination means we can quickly identify those projects eligible for tax relief including investments in new products, services, software and processes, freeing you up for growth.


Stephen & Ray, if I’m honest I never thought I’d be writing this email to you both BUT I’m ABSOLUTELY THRILLED that I am! My Finance Manager has just informed me that ZLX have made payment today of our R&D Tax Claim for the year 2018. Of all the years to have met you both and for ZLX to have delivered, as they said they would, on behalf of my Team, I would like to thank you both very much. I look forward to talking about how we approach the 2019 claim.

Event Production Company

This is INCREDIBLE, AMAZING. I actually had to speak to Ray to double check the figures earlier as I was reading whilst on various Zoom calls and couldn’t quite believe the numbers!! Ongoing, I’ll be much more prepared in terms of understanding how to pull the right information together for you.

Managing Director

Production & PR company

Working with Tim from ZLX was a positive experience for us. He advised, managed and completed our R&D tax claim with the minimum of fuss. This meant we could get on with the important business of managing our organisation, safe in the knowledge that our best interests were being looked after. As a result, we can highly recommend ZLX should other businesses be looking for a partner that brings expertise, efficiency and professionalism in their approach to R&D tax claims

We would highly recommend ZLX to anyone interested in applying for R&D tax credits. Their service was friendly, professional, and efficient and they really helped take the headache out of the entire process.

ZLX completed our R&D Tax Relief claim, the tax saving and cash rebate that have been realised have made a massive difference to our company.

We would have no hesitation in recommending future clients to ZLX. If you are considering making an R&D Tax Relief Claim then please look no further.

Managing Director

EOS Europe

ZLX promised to work alongside our accountant throughout the process, which they did. The outcome of the whole process was that we received an unexpected amount of money back from the HMRC that I was VERY GRATEFUL FOR. I would recommend any business owner to investigate the opportunity of a tax relief rebate and I would highly recommend that they put it in the hands of ZLX. ZLX were professional and ethical from the start of the process until the end.

They helped us in end to end planning and finalization of an R&D claim that resulted in maximizing our claim up-to twice as much as we had last year!

Executive Head

Currency Exchange Company

ZLX have been amazing throughout the process from start to finish. From our initial calls through to detailed and comprehensive explanations of the submission criteria, we knew we were in good hands. The ZLX staff have been patient and understanding of our individual business dynamics and secured us a sizable claim. This has allowed us to explore new avenues for our business moving forward and we will absolutely be using ZLX’s services again in the future.

I cannot recommend working with Ray, Amy, and ZLX highly enough.

The pandemic was almost career-ending for our agency (and many others) but your guidance and work meant we have managed to navigate our way out of a very tricky position. We’re looking forward to working with you again. Thank you so much for everything.
