R&D Tax Credits for Energy & Renewables Companies
Energy and renewables businesses are at the centre of the UK's transition to a cleaner, more resilient and more efficient energy system. From solar, wind and battery storage to hydrogen, smart grids, carbon reduction, heat networks, energy efficiency and low-carbon industrial technology, many companies in this sector are solving complex technical problems that may qualify for R&D Tax Credits.
Sector innovation
Innovation in Energy & Renewables
Innovation in energy and renewables often involves developing technology that must perform reliably in demanding commercial, environmental and infrastructure conditions. Qualifying R&D may arise where a business is developing or improving generation systems, storage, grid integration, monitoring, control software, energy efficiency, carbon reduction or low-carbon processes because existing solutions cannot meet the required performance, reliability, safety, cost or scalability requirements.
This includes work across:
- Renewable energy technology
- Solar and wind innovation
- Battery storage systems
- Smart grids and flexibility
- Hydrogen systems
- Heat pumps and heat networks
- Carbon capture and reduction
- Energy efficiency systems
- Power electronics
- Monitoring and control software
- Grid integration
- Low-carbon industrial processes
Energy and renewables R&D is strongest when the claim explains the technical challenge behind the sustainability outcome: what had to perform better, why existing solutions were not enough, and how the team tested or developed the answer.
A note from Simba Mareverwa
Energy R&D Claims Need to Explain the Technical Challenge Behind the Sustainability Outcome
Energy and renewables projects are often described in terms of sustainability, efficiency or carbon reduction, but HMRC will want to understand the scientific or technological uncertainty behind the project. A claim is not strengthened simply because a project is green, low-carbon or commercially important. It needs to show what technical advance was being sought and why the answer was not readily available.
That uncertainty may sit in generation efficiency, storage performance, grid connection, system stability, power conversion, thermal performance, degradation, control logic, data accuracy, integration with existing infrastructure, safety or scalability. A strong claim should explain the baseline technology, the limitation being addressed, the testing or development carried out, and the evidence showing how the business worked through the uncertainty.
Simba Mareverwa, InnoFund's Head of Compliance and Tax Disputes, helps ensure energy and renewables R&D claims are reviewed with compliance at the centre. His focus is making sure claims are not built around generic net zero language, but around clear technical evidence, eligible activity, competent professional input and defensible methodology.

Clear boundaries
Not Every Energy or Renewables Project Qualifies for R&D Tax Credits.
Not every energy project, renewable installation or efficiency improvement will qualify for R&D Tax Credits. The key question is whether the business faced scientific or technological uncertainty and carried out systematic work to resolve it.
Examples of work that may not qualify include:
- Standard renewable installation
- Routine solar or wind maintenance
- Off-the-shelf battery deployment
- Basic energy audits
- Standard efficiency upgrades
- Normal grid connection work
- Routine compliance testing
- Standard software configuration
- Commercial project management
- General sustainability reporting
- Normal equipment replacement
- Work after uncertainty is resolved
Energy and renewables projects often contain a mixture of qualifying and non-qualifying activity. InnoFund helps separate standard deployment from genuine R&D so the claim is accurate, compliant and defensible.
Eligible expenditure
Eligible R&D Costs for Energy & Renewables Businesses
Energy and renewables businesses may be able to claim relief on qualifying costs linked to eligible R&D projects, including:
- Engineering staff time
- Software developer time
- Technical director time
- Energy specialist time
- Employer NIC and pension costs
- Subcontracted R&D, where eligible
- Externally provided workers
- Software used for modelling or testing
- Cloud computing and data costs
- Prototype materials and components
- Testing and validation costs
- Consumables used in R&D
The treatment of subcontracted work, client-funded projects, externally provided workers, prototype materials, modelling software and technical consultancy can be particularly important in energy and renewables R&D claims.
InnoFund helps identify which costs are eligible and ensures the claim is built around the qualifying technical work, not just the wider sustainability or commercial project.
Evidence & scrutiny
HMRC Risk Areas for Energy & Renewables R&D Claims
HMRC is applying greater scrutiny to R&D Tax Credit claims, including claims from low-carbon, energy and infrastructure businesses. A strong claim must explain the technical uncertainty clearly and show why the work went beyond standard installation, deployment or commercial sustainability activity.
Common risk areas include:
- Treating green credentials as proof of R&D
- Weak technical uncertainty explanation
- No clear baseline of existing technology
- Overclaiming standard installations
- Claiming routine energy efficiency work
- Incorrect subcontractor treatment
- Claiming client-funded work incorrectly
- Poor records of testing or iteration
- No competent professional input
- Failing to separate qualifying and non-qualifying activity
- Generic net zero language
- Unclear project boundaries
InnoFund helps energy and renewables companies prepare claims that are clear, compliant and evidence-led. We focus on the technical work behind the sustainability outcome, the uncertainty faced, the process followed and the costs directly connected to qualifying activity.
