Our Enquiry Defence Service Includes

  • Strategy Planning

    Not all enquiries focus on the same elements of a claim. It’s critical that you understand what HMRC are asking for (and why) before making a response.

  • Full Enquiry Management

    We handle all correspondence with HMRC on your behalf. You stay informed with regular updates, while we manage the process to minimise disruption to your business.

  • Initial Claim Review & Risk Assessment

    We thoroughly review your original R&D claim to identify any potential weaknesses HMRC may challenge. You’ll receive a clear report highlighting strengths, risks, and recommended improvements.

  • Preparation of Robust Responses

    We draft clear, technically accurate responses to HMRC’s questions, written in language that aligns with both engineering reality and HMRC requirements.

  • Technical Defence & Evidence Strengthening

    Using our engineering background, we help build strong, evidence-based arguments that clearly demonstrate why your projects qualify as R&D.
