Why is enquiry defence important?
Whereas the industry average of HMRC enquiries into R&D Tax Credit claims is 20%, only 3% of the submissions made by randd are subject to such scrutiny. On the rare occasions it does happen, we navigate the enquiry as an integral part of our service.
Much of our business stems from taking on claims rejected by HMRC which were submitted by other providers.
Problems occur when those who submit claims are not sufficiently educated in the market and the result is sub-standard, especially in regard to meeting the continually evolving compliance requirements.
That situation usually means there is insufficient technical expertise to defend the claim – which is where randd comes in, with our vast experience proven to make a vital difference.
The benefits of consulting randd
A dedicated compliance team
To support our clients, partners and those seeking ad-hoc advice, we have assembled a specialist team to handle HMRC R&D enquiries. We offer expert guidance and insight into exactly what HMRC looks for.
A second opinion
Enquiries often arise from poorly presented claims. If your agent or accountant made errors, involving them in the enquiry response can complicate matters further instead of helping to resolve the issue.
Preservation of your claim value
As long as there has been no major procedural error, we aim to protect 100% of your claim’s value throughout the enquiry process.
Minimal disruption
From there, we will handle everything, keeping you focused on the most important thing – running your business successfully.

Enquiry Defence (FAQs)
How long does an enquiry take?
The duration of an HMRC R&D enquiry varies, but typical enquires take between 3–9 months, depending on complexity and whether appeals are needed.
Will defending an enquiry affect future claims?
No, not only can our enquiry experts defend your current claim but help ensure your future R&D submissions are more robust, so you are better positioned going forward.
Do you guarantee outcomes?
Due to variables in HMRC scrutiny, enquiry defence teams cannot guarantee an outcome, but here at randd we commit to delivering professional, evidence-based representation, putting you in the strongest possible position.
Why choose randd for enquiry defence?
We have an experienced, fully knowledgeable compliance team which provides an elevated service in comparison to other advisers who lack the technical expertise required within the nuances of R&D Tax Credit claims.
