Wiring built for industrial loads
Industrial facilities place the heaviest demands on electrical systems, with large machinery, continuous production lines and strict safety duties. Outdated or overloaded wiring in factories and warehouses can lead to dangerous faults, costly downtime and serious hazards. Industrial wiring and rewiring is designed to meet those demands, providing robust systems that support complex operations and comply with the relevant regulations. From a single small unit to a multi-site operation, the work is tailored to each site.
Rewiring an industrial site is not simply about replacing old cables. It is about building resilience, keeping people safe and planning for expansion. Many clients carry out rewiring alongside consumer unit and distribution board upgrades or book comprehensive electrical inspections to confirm the installation is sound. Planning ahead also means thinking about generation: the industrial solar comparison tool helps make sure rewiring today suits future renewable projects.
The rules that apply
- Electricity at Work Regulations 1989: employers must make sure electrical systems are constructed and maintained so as to prevent danger, and that anyone working on them is competent.
- BS 7671:2018+A4:2026: the current IET Wiring Regulations, used to design, install and test the installation.
- Construction (Design and Management) Regulations 2015: a rewire is construction work, so the client, designer and contractor all have planning and site-safety duties.
- Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR): where flammable dusts, vapours or gases are present, hazardous zones must be classified and equipment selected to suit them.
Part P of the Building Regulations applies to homes, not industrial premises.
The risks of neglecting wiring
Electrical faults can stop production lines, damage sensitive machinery or cause fires. Rewiring removes outdated circuits, improves capacity and puts protective devices such as RCDs and surge protection in place. For businesses handling high-value goods or working to tight deadlines, that resilience is vital.
How a project runs
The process includes a detailed assessment of your current installation, including maximum demand, three-phase load balance and the condition of submains and containment; design of a wiring system to suit; and phased installation to minimise downtime. If the upgrade needs more capacity from the network, the electrician will help you apply to your distribution network operator (DNO) early, because supply upgrades can take time.
Every project is tested and recorded on an Electrical Installation Certificate (EIC), giving clear evidence for insurers and auditors. After that, periodic inspection is recorded on an Electrical Installation Condition Report (EICR). Electrical Safety First recommends at least every five years for business premises, and the inspector may set a shorter interval for an industrial environment.
