Mechanical & Electrical R&D Tax Credits

INTRODUCTION

Understanding R&D within the Mechanical & Electrical Sector

Research and Development (R&D) tax relief is a financial incentive that can be claimed by qualified mechanical and electrical firms, offering significant financial benefits for innovative projects.

There is a well-established link between R&D tax relief and the Mechanical & Electrical (M&E) sector.

R&D often isn’t about lab experiments but hands-on problem-solving. HMRC recognises much of this as “brown coat” development, where technical uncertainties are tackled outside the laboratory to create new or improved products, processes, or materials.

Robotics and automation

Develops machines, control systems, and autonomous equipment that can perform physical tasks with high precision and efficiency.

Power and Energy systems Focuses on generators, motors, power grids, batteries, and renewable energy systems that deliver and manage electricity reliably.

Electronics and embedded systems Designs circuit boards, sensors, microcontrollers, and smart devices that enable modern products and connected technologies.

Manufacturing and production engineering Works on advanced machinery, process design, and industrial systems that improve productivity, quality, and scalability.

Thermal and fluid systems Studies heat transfer, cooling, propulsion, and fluid behaviour in systems such as engines, HVAC, turbines, and aerospace equipment.

Mechatronics and control systems Combines mechanics, electronics, and software to create intelligent systems that sense, decide, and act in real time.

Examples of R&D activity in Mechanical & Electrical

Development & testing of evaluation designs and systems
Development of hybrid designs and experimenting with embedded learning approaches such as rapid‑cycle evaluation.
Design and testing of data collection and design tools
To improve data quality, real-world design reliability, reduce bias, or lower collection costs.
Design & development of hybrid systems
Sustainable design and energy efficiency, and addressing overheating or cooling requirements.
Reliable integration of hybrid systems
Combination of multiple energy, mechanical, or electrical technologies into a single, efficient, and resilient system.

New approaches to containment in geometrically constrained sites
Methods for managing mechanical, electrical, or fluid systems where space is extremely limited or irregularly shaped.
Development of M&E frameworks to modernise building performance
Listed structures and unique constraints such as laboratory or hospital environments.

Architectural projects may include sustainability initiatives, listed buildings, complex site conditions, changing regulations, advanced engineering solutions, value engineering with innovative materials or techniques, and new build methods. This list isn’t exhaustive, and each project should be assessed on its own merits to identify potential R&D opportunities.
