Quick answer
The Enhanced R&D Intensive Support (ERIS) scheme provides a more generous payable tax credit to loss-making UK SMEs whose qualifying R&D expenditure is at least 30% of total expenditure. It sits alongside the merged R&D Expenditure Credit and supports R&D-heavy startups. Eligible companies can claim a 14.5% payable credit on enhanced qualifying expenditure.

Advisor view
This relief rewards evidence, not enthusiasm. The strongest claims are built throughout the year — contemporaneous technical narratives, time-tracked staff costs, and a clear line between qualifying R&D and routine work.
Frequently asked questions
- Who is R&D Intensive SME Scheme (ERIS) really for?
- It works best for organisations that already meet the eligibility test on paper and have the operational maturity to deliver — not for businesses hoping the application will force them to formalise.
- What are the most common reasons applications are rejected?
- Weak evidence, eligibility misses, and applications that read as business as usual rather than the specific intent of the scheme. Most rejections are avoidable with earlier preparation.
- Can early-stage startups apply?
- Sometimes — but the strongest applicants usually have at least minimum trading history, a defined plan and the team to deliver. If you are pre-revenue with no plan, expect to be too early.
- How competitive is it?
- Demand routinely outstrips supply for the high-profile UK programmes. Treat any competitive call as a serious bid that needs four to six weeks of preparation, not a weekend.
- What should I prepare before I apply?
- A short written summary of what you are doing and why it qualifies, your latest accounts or forecasts, and any partner or evidence the scheme expects. Get adviser sign-off before submission.
- What happens after a successful application?
- Expect monitoring, reporting and milestone evidence. Plan the reporting cadence and internal owner before the funding lands, not afterwards.
Usually too early when
Advisor signal
You have not yet incurred qualifying R&D expenditure, do not have a UK-resident company in scope, or cannot evidence the scientific or technological uncertainty being resolved.
Eligibility
Loss-making UK SMEs with qualifying R&D expenditure of 30% or more of total expenditure.
Common reasons applications fail
Weak technical narratives, claiming non-qualifying expenditure, missing the competent professional test, ineligible subcontractor costs, late notification.
What improves your odds
A competent professional sign-off, a written technical narrative per project, separated qualifying and non-qualifying costs, and a clear audit trail.
Typical successful applicant
A UK company carrying out genuine scientific or technological R&D, with a competent professional and a finance function that can isolate qualifying costs.
Common misconceptions
Routine software development, market research and aesthetic design generally do not qualify. The statutory test is an advance in the field, not in your company.
What comes next
File the claim with a full technical and financial report, retain working papers for six years, and assume HMRC may open an enquiry.
Funding context
Often used alongside grant funding and equity. Notified state aid affects which R&D relief regime applies, and the rules vary by company size and R&D intensity.
