We are not what you would expect from 'typical' accountants or tax advisers. We do not have standard ways of working or processes that you have to fit within.

Keeping it simple, we make two promises to every company we work with:

  1. You will always speak to a Chartered Tax Adviser that is experienced at providing advice on R&D tax relief.
  2. You will always receive outstanding service, regardless of the size of your business.

Our approach is to keep our ways of working flexible, to fit around our clients. By doing this we ensure that we are able to deliver a genuinely excellent and uncompromised service. No barriers, no red tape. Our ethos is quality over quantity.

Our Team


Nikki is a Chartered Tax Adviser with a significant amount of R&D tax relief experience.

She has a passion for providing a first-class service that is admired by all that know her. It is her natural empathy, patience and sense of responsibility that results in clear, relevant and reliable advice.

In her personal life, Nikki first and foremost loves being a mum to our gorgeous little boy, Theo. She also loves playing the saxophone, reading and catching up with friends over a glass of vino or two!



Graham is a Chartered Tax Adviser who has specialised in R&D tax relief for most of his tax career. He has helped hundreds of innovative companies claim R&D tax relief, generating a total benefit in excess of £15M for his clients.

Graham delivers excellent results by combining a genuine interest in his clients work with a professional and efficient approach.

Outside of work, Graham is a keen sportsman. He used to fence for Great Britain! He’s enjoying Wolves’ current success in the premier league and enjoys a kick around himself. Graham will never pass up the opportunity to sample a fine whisky!

Our Story

To answer the first question that usually crops up – yes, we are a husband and wife team!

Stage 1: Exams, exams, exams.

Stage 2: Long hours, experience, promotion. Long hours, experience, promotion. Long hours, experience, promotion.

Stage 3: Start a family - realise things need to change!

Having worked in respected firms of all sizes, we know and love the buzz of a well-functioning office. It was only when we had our first son, Theo, that we realised for us there was far more to life than working 80+ hour weeks. That is the main reason why we started Heydon Innovation.

We work hard, advise on interesting and technically challenging projects, and help innovative companies claim millions of pounds of R&D tax relief. However, we also now have enough time and energy to have fun as a family.

We strongly believe that people do their best work when they are alert, happy and enthused.

Service excellence is our passion and we enjoy working in an environment where we can provide this without compromise or distraction. So rather than focusing on ambitious growth targets, we have established a business focussed entirely on this excellent service.

We tend to shun the corporate approach that people generally expect from accountants and tax advisers. That is just not who we are! Heydon Innovation is an R&D tax relief consultancy that offers a truly excellent service and a down-to-earth approach.

R&D Tax Relief

A generous tax relief opportunity for innovative and forward thinking companies, creating considerable benefits for shareholders and Directors.

Already Claiming?

The approach taken by advisers differs significantly. This affects the size and accuracy of a claim, along with the time investment required from you.

Heydon Insights

All sectors can qualify for R&D tax relief. From software development to manufacturing. Rocket science to construction. Food and drink to engineering.

If you are already claiming, we are happy to review your most recent claim for free. We may be able to increase the value and/or make the process easier for you.

Any company that uses science or technology to work on innovative projects should review whether it qualifies.

Contact us to discuss your claim

We were delighted that Heydon Innovation was able to help us with our R&D tax credit claim. It was very important to us that the claim was considered in its completion. Heydon Innovation approached this both professionally, and most importantly with the highest standards of ethics.

Not only did I learn a great deal, but also the guidance and assistance I received, particularly in view of the tight timeline, was exactly the high standards that we always aim to deliver to our own clients.
