R&D Tax Credits for Marine & Aviation Companies

Chart new courses by rewarding your innovation efforts, claiming potentially thousands in R&D Tax Relief.

Claiming Tax Credits for Marine, Offshore & Aerospace Engineering R&D

The UK Marine & Aviation sector is a key driver of global trade and connectivity, continually adapting to new technologies, environmental pressures, and strict regulatory standards. From decarbonisation and alternative fuels to advanced safety systems and digital innovation, businesses face complex challenges but also opportunities to deliver cutting-edge solutions.

R&D Tax Credits can provide valuable funding by reducing tax liabilities or delivering cash injections. Projects involving technological advancements in areas such as propulsion, aerodynamics, materials, navigation systems, subsea engineering, and offshore structures may qualify where companies are attempting to overcome technical uncertainty.

Recent changes to the R&D Tax Credit scheme have also impacted how claims are assessed across engineering sectors. You can explore how R&D Tax Credits work in more detail in our guide to R&D Tax Credits.

Which activities qualify for R&D Tax Credits in Marine, Offshore & Aerospace Engineering?

Companies operating across marine, offshore, and aerospace engineering may qualify for R&D Tax Relief when addressing technological uncertainty or developing new capabilities.

Examples of qualifying projects include:

Developing new or improved propulsion or engine systems

Designing advanced aerodynamics or hydrodynamics for improved efficiency

Enhancing safety, control, or navigation systems

Prototyping and trialling innovative vessel or aircraft designs

Researching and testing alternative fuels or decarbonisation methods

Creating lightweight, durable, or corrosion-resistant materials

Developing digital tools, automation, or smart monitoring technologies

Improving manufacturing, maintenance, or repair processes

Projects like these can support subsea R&D Tax Credit claims, offshore engineering innovation, and aerospace R&D projects eligible for tax relief. Find out more about whether your activities qualify for R&D Tax Credits.

Did you know?

Under HMRC rules, your business does not need to succeed to qualify. If you have attempted to overcome technical uncertainty through propulsion systems, aerodynamics, materials, or navigation technologies, you could be eligible for R&D Tax Credits.

Many businesses involved in offshore structures, subsea engineering, and aerospace development successfully claim R&D Tax Relief even when projects do not reach a final commercial outcome.

Can offshore oil and gas projects qualify for R&D Tax Relief?

Companies involved in offshore oil or gas operations may qualify for R&D Tax Relief when developing new technologies, improving offshore structures, or solving complex engineering challenges in subsea environments.

Do aerospace companies qualify for R&D Tax Credits?

Yes. Aerospace companies often qualify when designing new components, improving aerodynamics, testing new materials, or developing innovative aviation systems that improve processes.

How much can marine or aerospace R&D Tax Credit claims be worth?

The amount your company can claim depends on eligible R&D expenditure, such as:

  • Staff costs
  • Subcontractor work
  • Materials used during development

Many businesses use an R&D Tax Credit calculator to estimate potential claims before submitting.

How long does a marine or aerospace R&D Tax Credit claim take?

The timeframe for an aerospace, offshore, or subsea R&D Tax Credit claim can vary depending on the complexity of the project and the quality of the supporting documentation.

In most cases, once a claim has been submitted to HMRC, companies receive a response within several weeks. More complex claims, particularly those involving offshore engineering or aerospace innovation, may take longer if additional information is requested during the review process.
