If your business is investing in innovation — developing new products, improving existing processes, or solving technical challenges — you could be eligible for R&D tax credits worth tens or even hundreds of thousands of pounds. Yet millions of pounds of legitimate claims go unclaimed each year because businesses simply do not know what qualifies or how to prepare a robust submission.
R&D tax credits are one of the most valuable reliefs available to UK companies. They are not a loan or a grant — they are a reduction in your corporation tax bill or, for loss-making companies, a cash payment from HMRC. The scheme is designed to reward genuine innovation and incentivise UK businesses to invest in research and development.
This guide explains how R&D tax credits work, what qualifies, how much you can claim, and how our specialist service helps you prepare and submit a compliant claim that maximises your relief while minimising HMRC enquiry risk.
What Are R&D Tax Credits?
R&D tax credits are a government-backed relief that allows UK companies to reduce their tax bill — or receive a cash sum — based on qualifying research and development expenditure. The scheme is administered by HMRC and is available to companies across all sectors, not just those traditionally associated with R&D.
There are two main schemes:
- SME R&D Relief: For companies with fewer than 500 employees and either turnover under €100 million or a balance sheet under €86 million. Qualifying SMEs can claim an additional 86% deduction on eligible R&D costs on top of the normal trading deduction, and loss-making companies can surrender losses for a payable tax credit worth up to 27% of qualifying expenditure (for accounting periods beginning before 1 April 2025; new merged RDEC-like rules apply from April 2025).
- R&D Expenditure Credit (RDEC): For large companies and SMEs that have been subcontracted to carry out R&D. RDEC provides a 20% taxable credit on qualifying expenditure, worth approximately 15% after corporation tax. The credit is available regardless of whether the company is in profit or loss.
To qualify, your project must seek to achieve an advance in science or technology by resolving scientific or technological uncertainty. The work must be more than routine development — it must involve technical challenge that a competent professional in the field could not readily work out.
Key point: HMRC's definition of R&D is broader than many businesses expect. It is not limited to laboratories and white coats. Software development, engineering improvements, manufacturing process innovations, and construction methodology advances can all qualify if they involve technical uncertainty that required a systematic process of investigation.
Does Your Business Qualify?
Qualification depends on the nature of the work, not the industry you operate in. Any UK company that carries out projects to resolve scientific or technological uncertainty can claim. The key test is whether a competent professional working in your field would consider the outcome uncertain at the outset.
Qualifying Activities
- Developing new products, services, or processes
- Enhancing or improving existing products, services, or processes
- Creating prototypes, trial models, or testing systems
- Developing new materials, devices, or software
- Conducting applied research to solve specific technical problems
- Designing and building production equipment or tooling
- Developing or improving manufacturing methods
- Field trials and beta testing that resolve technical uncertainty

Pharmaceutical development, medical devices, diagnostics, biotech, clinical trial methodology, and regenerative medicine.
How Much Can You Claim?
The value of your claim depends on your company size, profitability, and the volume of qualifying R&D expenditure. Below are typical claim scenarios to illustrate the potential benefit.
| Scenario | R&D Spend | Scheme | Benefit | Type |
|---|---|---|---|---|
| Small loss-making tech startup | £80,000 | SME | £21,600 | Cash credit |
| Profitable manufacturing SME | £150,000 | SME | £37,800 | CT reduction |
| Mid-size engineering firm | £500,000 | SME | £126,000 | Cash credit / CT reduction |
| Large construction company | £2,000,000 | RDEC | £300,000 | Taxable credit (≈£240k after CT) |
| Loss-making life sciences firm | £1,200,000 | SME | £324,000 | Cash credit |
These figures are illustrative. Actual claim values depend on detailed analysis of your specific R&D activities, eligible costs, and accounting period. The rates shown reflect the current SME scheme (86% enhanced deduction + 27% payable credit for loss-makers). From April 2025, new merged rules apply under the single RDEC framework.
What Costs Can You Include?
Eligible costs for R&D tax credit claims include:
- Staff costs: Salaries, wages, bonuses, employer NI, and pension contributions for staff directly involved in qualifying R&D activities
- Subcontractor costs: Payments to subcontractors for R&D activities (limited to 65% of total qualifying costs under the SME scheme)
- Consumables: Materials, utilities, and other items consumed or transformed in the R&D process
- Software licences: Directly used for qualifying R&D activities
- Externally provided workers: Agency staff and other workers providing services directly to the company

We provide end-to-end R&D tax credit claim support, from eligibility assessment through to HMRC submission and enquiry defence. Our service is designed to maximise your claim while ensuring every submission meets HMRC's compliance standards.
Eligibility Review
We conduct a thorough assessment of your R&D activities against HMRC's qualifying criteria, identifying all projects and costs that may be eligible. This includes retrospective reviews of unclaimed expenditure from prior periods.
Technical Report Writing
A robust technical narrative is the foundation of a successful claim. We document your R&D projects in plain English, describing the technical uncertainties, the advance sought, and the work undertaken to resolve them.
Cost Identification
We analyse your financial records to identify and categorise all qualifying R&D expenditure, ensuring every eligible pound is captured while excluding costs that do not meet HMRC's criteria.
HMRC Submission
We prepare and submit the full claim package including amended corporation tax returns, R&D supplementary pages, technical narratives, and cost schedules — all formatted to HMRC's expected standards.

HMRC enquiries into R&D claims are increasingly common. Every claim we prepare is built to tribunal standard from day one, with comprehensive supporting evidence and clear technical justification.
Claim Projection

Why Local Expertise Matters
R&D tax credit claims require a deep understanding of both the technical and financial aspects of your business. While many national firms offer R&D claims services, they often rely on generic templates and standardised approaches that miss the nuances of specific sectors. Our team combines corporate tax expertise with hands-on experience across the industries we serve — from manufacturing floors to software development studios. We prepare every claim from first principles, rooted in the actual technical work your business has done.
