Our focus is on producing practical, future-ready solutions that reduce delays, streamline installation work and improve long-term reliability.

Full-Service Electrical Design Solutions from Uni-lec

Your project deserves more than a basic diagram. A strong electrical design sets the standard for safety, performance and long-term reliability. When you choose Uni-Lec, you receive a complete design package built around your specific requirements, installation conditions and operational expectations.

Your design begins with a clear understanding of what you are trying to achieve. We look at the nature of your building, the equipment you plan to use, future expansion, environmental influences and compliance standards. Once we have this, we produce coordinated CAD drawings, electrical layout plans, cable calculations, lighting designs and the supporting documentation that your contractors need to deliver the project correctly.

Because your installation must work in the real world, everything is built around practical experience. This means fewer delays, fewer surprises on site and an electrical system that is easier for you to own and operate. We have a over a decade of experience in delivering designs for many successful electrical installations, giving us vast experience in delivering the right solutions for your needs. If you are based in Plymouth, Devon, Cornwall or the Southwest, you can expect a complete design service that supports commercial, industrial and high-end residential projects.

Our Commitment to Quality

Your design is created with care, accuracy and compliance in mind. Every project follows British Standards, local regulations and recognised industry practices. We also consider energy efficiency measures, eco-friendly technologies, installation methods and environmental influences so your system remains reliable and future-ready.

CAD (Computer-Aided Design)

Your CAD drawings form the foundation of your design. They give you a precise visual plan that everyone can follow, from architects and builders to your installation team. CAD helps you understand how your electrical system fits within the wider build, ensuring that containment routes, equipment locations and wiring paths are aligned before anyone starts work.

Benefits of this include

  • Drawings that reduce on-site changes

  • Better coordination between trades

  • A clear view of how electrical components sit within the building

  • Documentation that supports compliance and future updates

Electrical Layout Plans

Your layout plan shows exactly how power, lighting and control systems flow through your building. This ensures safe positioning, logical wiring routes and smooth integration with other systems such as AV, networking and smart controls.

This approach gives you

  • A structured plan your contractors can follow

  • A layout that supports everyday usability

  • Better preparation for future equipment or system upgrades

  • Confidence that everything aligns with British Standards and local regulations

Cable Calculations

Accurate cable sizing protects your building, your equipment and your future energy costs. Your design includes cable calculations that take into account load demands, voltage drop, installation methods, environmental influences and any future plans for expansion.

This provides

  • Safe, compliant cable selection

  • Improved long-term reliability

  • Fewer risks during installation

  • A system that can handle real-world usage

Lighting Design

Your lighting design shapes the comfort, safety and efficiency of your space. With the right plan in place, you can create a balanced environment that supports the way your building is used while keeping energy consumption under control.

 

This gives you

  • Lighting suited to each area of your building
  • Reduced running costs through energy-efficient choices
  • Improved safety through well-planned emergency lighting
  • Compatibility with modern controls and occupancy sensing

Cabinet Design

Your cabinet layout determines how tidy, accessible and service-friendly your electrical distribution will be. A clear, well-designed cabinet helps installers work efficiently and makes future maintenance much easier.

This results in

  • Organised and easy-to-service distribution boards

  • Logical circuit arrangements that support safety

  • Space for smart controllers or future additions

  • A professional, structured finish to the installation

Operational Maintenance Manuals

We provide comprehensive Operational Maintenance Manuals (OMMs) for all projects, detailing equipment specifications, layouts, maintenance schedules, and testing requirements.

These manuals ensure your building staff or facilities managers can operate and maintain systems safely, efficiently, and in compliance with BS 7671 and other regulations. Our OMMs also simplify future upgrades, troubleshooting, and contractor handovers.

What you gain

  • System information that is easy to follow

  • Clear maintenance guidance

  • Wiring diagrams or schedules where required

  • Documentation that helps your system remain compliant throughout its life
