Cable Tray Installation Best Practices for UK Contractors

22.08.2025

In the UK construction industry, cable tray systems are one of the most reliable and efficient methods for supporting electrical wiring in commercial, industrial, and residential projects. A well-installed cable tray system ensures safety, accessibility, and long-term performance, while also keeping projects compliant with UK regulations.

At First Fix Electrical LTD, we specialise in cable installation and containment solutions across the UK. Based in North West England, we support contractors and developers with professional, on-time delivery. Here are some of the best practices we recommend for cable tray installation.

1. Plan and Design Early

Early coordination with other trades is key. Before installation begins, ensure that tray routes are designed to avoid clashes with HVAC, plumbing, and structural elements. Proper design reduces rework, delays, and additional costs.

2. Use the Right Materials

Cable trays come in ladder, perforated, wire mesh, and solid-bottom types. The correct choice depends on cable load, environment, and accessibility requirements. Always use compliant, high-quality products from trusted suppliers to guarantee safety and durability.

3. Follow Load and Support Guidelines

Overloading trays is a common mistake. Follow manufacturer guidelines for load capacity and spacing of supports (typically every 1.5 to 2 metres). This prevents sagging and ensures the tray system remains safe and efficient.

4. Ensure Proper Fixings and Alignment

Secure fixings are crucial for long-term stability. Always use corrosion-resistant fasteners and ensure trays are level and aligned. Neat installation not only improves safety but also makes future maintenance easier.

5. Maintain Safety and Compliance

Work in line with UK regulations, including BS 7671 (IET Wiring Regulations). Ensure correct earthing, bonding, and fire-stopping practices are followed. At First Fix Electrical LTD, safety is at the core of every project we deliver.

6. Consider Future Expansion

Projects often evolve. Design your tray systems with spare capacity and easy access for future cable additions. This foresight saves time and cost during later upgrades.
