Enquiry Resolution Service
At Streets Innovation, the team understands that receiving a Notice of Enquiry from HMRC can be a daunting and disruptive experience for any business. That’s why the ERS team is built not only on technical knowledge but on a deep well of practical experience and specialist insight.
Proactive Support When It Matters Most: Streets’ Enquiry Resolution Services
An HMRC Notice to Enquiry doesn’t have to be a setback. With Streets Innovation’s Enquiry Resolution Services (ERS), businesses gain a trusted partner that can demystify the process, advocate on their behalf, and work towards a positive, timely resolution.
Backed by technical depth and a client-first approach, Streets helps transform complexity into clarity and stress into confidence.
In recent years, the landscape of R&D tax relief has shifted significantly. HMRC has increased the scrutiny applied to claims, with Notices of Enquiry now affecting up to 20% of all submissions, a stark rise from the previous 1%. This surge stems from HMRC’s retrospective review of the 2021 and 2022 claim periods, during which it identified an estimated £1 billion of the £7 billion paid out in tax credits as either fraudulent or erroneous.
These figures highlight a critical truth: the need for accuracy, detail, and compliance in every R&D claim has never been more important. Yet, even with the most robust preparation, the reality is that any claim, regardless of its size or merit, can still be selected at random for enquiry.
The team at Streets Innovation consists of seasoned Compliance Specialists, Engineers, Tax Advisors, and even PhD holders in disciplines such as Nuclear Engineering, all bringing over 25 years of combined expertise in resolving R&D enquiries. Their shared mission is to reassure, guide, and advocate, ensuring businesses understand that an enquiry is often procedural, and not an accusation of wrongdoing.
The ERS process is structured and comprehensive, designed to address HMRC’s concerns while minimising disruption to the business:
Thorough Claim Review
Every engagement begins with a detailed assessment of the submitted R&D claim, including any prior correspondence with HMRC. This helps to establish the strengths of the original claim and identify areas requiring further clarification.
Collaborative Consultation
The team arranges a meeting, either virtually or in person, to walk through the enquiry context, HMRC’s requests, and the supporting materials provided to date. Where necessary, the team references current legislation and HMRC guidance to ensure the business is well-informed.
Targeted Evidence Gathering
If additional documentation or technical detail is required, Streets Innovation works with the business to collect the relevant information, ensuring that the response is as complete and persuasive as possible.
Drafting a Strategic Response
Once all required materials are in place, the ERS team drafts a formal response for the business to review. They also advise on any enhancements that may improve the submission’s impact and assist in accelerating a resolution.
In some cases, despite a thorough and well-managed response, a Notice of Enquiry may not result in immediate closure or resolution. When this occurs, there are structured avenues of appeal available to businesses and Streets Innovation stands ready to support every step of the way.
ERS Process
The ERS process is structured and comprehensive, designed to address HMRC’s concerns while minimising disruption to the business:
Solicitor’s Office and Legal Services (SOLS)

Alternative Dispute Resolution (ADR)

Where necessary, a formal judicial process that offers businesses the opportunity to have their case heard independently of HMRC.
