Commercial Electrical Contractors in Leicester

Professional commercial electrical contracting, three-phase power distribution, industrial fit-outs, statutory EICR compliance testing, and planned preventative maintenance for businesses across Leicester and Leicestershire. Dependable electrical infrastructure is essential for every productive commercial workplace. Whether you are running precision manufacturing machinery, powering high-density data and server rooms, or maintaining safe illumination across multi-storey corporate offices, electrical faults or inadequate power design can bring business operations to an expensive standstill. At Newton Electrical and Mechanical, our certified commercial electrical contractors deliver complete electrical design, installation, testing, and maintenance services configured to satisfy current UK wiring codes and industrial safety standards. As NICEIC Approved Contractors, SafeContractor approved, and Constructionline Gold accredited specialists, we execute commercial, retail, logistics, and industrial electrical engineering projects, ensuring your facilities remain fully powered, energy-efficient, and legally compliant.

Comprehensive Commercial Electrical Contracting Services

Our commercial division undertakes large-scale fit-outs, system upgrades, and statutory testing programmes:
  • Three-Phase Power Distribution and Switchgear: Sizing, supplying, and installing high-capacity three-phase (400V) distribution boards, panel boards, and busbar trunking systems to safely power industrial equipment and commercial sub-circuits.
  • Commercial Fit-Outs and Overhead Power Drops: Designing complete containment arrays (heavy-duty galvanised cable tray, basket, and steel conduit) and overhead drop feeds for assembly lines, industrial machinery, and office partitions.
  • Statutory Electrical Safety Inspections (EICR): Conducting rigorous 5-year Electrical Installation Condition Reports (EICRs) and thermal imaging surveys to identify overloaded circuits, deterioration, and code non-compliance before electrical failures occur.
  • Commercial LED Lighting Refits and Controls: Modernising inefficient fluorescent and metal-halide fixtures with low-energy commercial LED panels, high-bay fittings, daylight harvesting sensors, and automated PIR occupancy detection.
  • Emergency Lighting Systems (BS5266): Designing, installing, and certifying statutory emergency escape lighting and illuminated exit signs, supported by automated key-switch test facilities and digital compliance logbooks.
  • Dedicated Plant-Room and HVAC Power Feeds: Wiring motor control centres (MCCs), variable speed drives (VFDs), twin-head circulating pumps, and commercial heating plant rooms with direct BMS integration.

Frequently asked questions

What commercial sectors do your electrical contractors serve in Leicester?

We serve a wide spectrum of commercial premises across Leicester, including corporate office suites, manufacturing factories, logistics warehouses, secondary and higher education campuses, retail business parks, automotive workshops, and local authority healthcare facilities.

What documentation is issued upon completion of commercial electrical work?

As NICEIC Approved Contractors, we issue official Electrical Installation Certificates (EICs) or Minor Electrical Installation Works Certificates (MEIWCs) for all new work and modifications, alongside statutory Electrical Installation Condition Reports (EICRs) for inspection testing. We also provide Building Regulations Part P compliance notifications where applicable.

How frequently does a commercial facility require an EICR in the UK?

Under the Electricity at Work Regulations 1989 and BS7671 guidance, commercial offices and retail units must undergo an EICR safety inspection at least once every five years (or upon a change of occupancy). Industrial buildings and manufacturing plants with higher environmental stresses typically require testing every three years.

Can your team upgrade our building power supply from single-phase to three-phase?

Yes. When businesses install high-output machinery, commercial HVAC equipment, or commercial EV chargers, three-phase power is often essential. We calculate your projected maximum demand, liaise directly with the Distribution Network Operator (National Grid Electricity Distribution) to coordinate incoming mains upgrades, and install new three-phase distribution panels and switchgear internally.

How do you prevent disruption to our workforce during commercial electrical refits?

We structure project delivery around your operational requirements. Our project managers organise work in distinct stages, prefabricating containment off site where possible, utilising temporary power bypasses, and scheduling power interruptions during evenings or weekends so your daytime operations continue uninterrupted.

Can you combine commercial electrical contracting with heating and plant-room servicing?

Yes. This is a core advantage of partnering with Newton. Because our in-house engineering capabilities combine certified electricians and Gas Safe commercial heating engineers, we design, wire, plumb, and commission commercial boiler plants, circulating pumps, and building controls without third-party subcontractor friction.

Sam responded promptly to my air con enquiry and even visited me at short notice to firm up the scope. We were fitted in quickly, and Dave managed the job well, with the team carrying out a nice tidy install. Would definitely use again in the future and I will certainly recommend to others.

After struggling with underfloor heating that had been left in a broken state by a previous company, my dad endured almost no heating throughout the winter. It was a frustrating and uncomfortable situation until Sam from Newton Electrical and Mechanical came to the rescue. Sam was incredibly professional and knowledgeable. He quickly identified the issues, including faulty wiring and broken pumps, and thoroughly cleaned the entire system. Within just two weeks, the system was completely fixed and working perfectly. The level of care, expertise, and efficiency from Newton Electrical and Mechanical was outstanding. I can’t thank them enough for the difference they made. I’d highly recommend them to anyone needing reliable and skilled professionals for their heating or electrical needs.

We used Newton Electrical and Mechanical for all of our electrical and plumbing work in a large home renovation project and I would thoroughly recommend them. Sam Dave and colleagues have all been knowledgable, reliable, trustworthy and communicative and take pride in completing work to a high standard, a pleasure to work with. As with any large project dealing with multiple trades, some things didn’t quite go to plan, but I found that any issues that Newton Electrical could help with were resolved quickly and without fuss. It’s very hard to find tradespeople you can trust, but if you’re reading this, congrats- you’ve just found some.

I had Sam and Dave from Newton Electrical come to my studio to extend an internet cable two floors down, and I couldn’t be happier with the service. They arrived on time, well-dressed, and took the time to check everything carefully before starting the work. They were extremely professional throughout, explained the process clearly, and made sure everything was set up exactly as needed. The work was done quickly, efficiently, and with great attention to detail. They truly went above and beyond to accommodate my requirements, and I highly recommend them to anyone looking for reliable and professional electrical work.
