    What qualifies for R&D tax relief?

    R&D activity varies depending on the industry and the scope is huge. The key activities must be part of a specific project to make an advance in science or technology. The project must also relate to your company’s trade.

    Has your business:

    Looked for an advance in Science and Technology?

    Had to overcome uncertainty?

    Attempted to overcome this uncertainty?

    Solved an uncertainty that couldn't be easily worked out by a professional in the field?

    If your company can demonstrate that they worked to solve an issue and somehow advanced the overall knowledge in their field/industry, you could qualify.


    R&D tax relief allows you to claim back the costs of items that are directly used and consumed in qualifying R&D projects. According to HMRC, as of 30 June 2020, £5.3bn of R&D tax relief support has been claimed for 2018-19 by businesses.

    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

    Executive Head

    Currency Exchange Company

    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.

    Managing Director

    Event Production Company

    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.

    Eco-friendly Energy Solutions

    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.
