What Are Industrial Electrical Services?

Industrial electrical services cover the installation, maintenance, testing, and repair of electrical systems used in industrial environments. These systems operate at higher voltages, carry heavier loads, and require specialist knowledge to meet safety regulations and operational demands.

Our industrial electricians support facilities across manufacturing, logistics, warehousing, food production, and processing industries.

Key Responsibilities of an Industrial Electrician

Industrial electrical work requires a high level of technical expertise, precision, and compliance. Our industrial electricians are responsible for installing, maintaining, and supporting complex electrical systems that power modern industrial operations. This includes the installation, testing, and ongoing maintenance of large-scale electrical infrastructure such as three-phase power systems, transformers, industrial motors, and power distribution networks, all designed to handle high loads safely and efficiently.

A critical part of our role is troubleshooting and fault diagnosis. We identify and repair electrical issues within machinery, automated production lines, and robotic systems to minimise downtime and restore operations quickly. Safety and compliance are at the core of everything we do, ensuring all work meets strict UK electrical regulations, industry standards, and site-specific safety requirements.

Our industrial electricians also work extensively with control systems, including Programmable Logic Controllers (PLCs), motor control centres (MCCs), and Variable Frequency Drives (VFDs), supporting automation, efficiency, and system reliability. Throughout every project, we read and interpret technical drawings, schematics, and blueprints to ensure accurate installation, documentation, and long-term system performance.

Industrial Power & Electrical Infrastructure

The power supply within any industrial or large-scale business environment is the backbone of daily operations. Without a safe, reliable, and well-managed electrical distribution system, productivity quickly comes to a standstill. As businesses grow and operational demands increase, protecting and future-proofing mains distribution systems becomes more critical than ever.

Our industrial electrical services are designed to keep clients operational even during high-demand periods or unexpected failures. This includes proactive system monitoring, robust backup solutions, and carefully planned contingency measures to reduce risk and maintain continuity. Through intelligent design, preventative maintenance, and responsive support, we help safeguard your electrical infrastructure against failure while improving efficiency, safety, and long-term performance.

Professional & Authoritative

Our industrial clients play a critical role in wider supply chains, and we understand that even short periods of electrical downtime can have a far-reaching and costly impact — not just on your operation, but on the businesses that rely on you. That’s why our approach goes beyond reactive call-outs. We work as an integrated electrical partner, aligning our services with your operational priorities, production schedules, and risk profile.

To keep industrial facilities safe, compliant, and operational, we focus on three core areas of electrical maintenance and support.

Reactive Electrical Maintenance

Despite the best planning, electrical faults can still occur. Our reactive maintenance and breakdown repair service is designed to respond quickly and effectively to minimise disruption. We diagnose faults efficiently, carry out safe repairs, and restore power with minimal downtime, helping you resume operations as fast as possible.

Statutory Electrical Maintenance

UK businesses have a legal duty under the Electricity at Work Regulations 1989 to ensure electrical systems and equipment are safe and properly maintained. This includes regular inspection, testing, and maintenance of fixed installations, machinery, emergency lighting, and portable electrical equipment where applicable. Our statutory electrical maintenance services help you meet these obligations, demonstrate compliance, and maintain a safe working environment for staff and visitors.

Preventative Electrical Maintenance

Preventative electrical maintenance is the most effective way to reduce risk and avoid unexpected failures. Through scheduled inspections, testing, and system monitoring, we identify signs of wear, overload, or deterioration before they develop into critical faults. By putting proactive measures in place, we help reduce long-term repair costs, extend equipment life, and ensure your electrical systems continue to perform reliably under operational pressure.

What is a Level 2 Thermography survey and why does it matter?

A Level 2 Thermography survey is carried out by a certified thermographer qualified to the highest industry standard. Unlike a basic thermal scan, a Level 2 survey includes full analysis, interpretation, and a detailed written report that is recognised by insurers and accepted as evidence of compliance for health & safety audits. Very few electrical contractors in London hold Level 2 certification — DB Site Services does.

Do your thermal imaging surveys satisfy insurance requirements?

Thermography certification means our survey reports meet the evidence standard required by most commercial and industrial insurers. A standard visual inspection or uncertified thermal scan does not carry the same weight — and in the event of a claim, that difference matters.

Are you NICEIC approved?

Yes. DB Site Services are NICEIC Approved Contractors — one of the most recognised and respected electrical accreditations in the UK. It means every job we carry out is independently verified to meet the highest safety and quality standards.

What is Planned Preventative Maintenance (PPM) and do I need it?

PPM is a scheduled programme of electrical inspections, testing, and maintenance designed to identify and resolve issues before they cause failures or compliance breaches. Under the Electricity at Work Regulations 1989, businesses have a legal duty to maintain electrical systems safely — a PPM programme is the most effective way to demonstrate that duty is being met.

Can you work around our production schedule?

Yes. We plan all industrial electrical work around your operation to keep disruption to an absolute minimum. This includes out-of-hours work, weekend shifts, and phased programmes designed around your production calendar.

What size industrial sites do you work in?

We work with industrial sites of all sizes across London — from single-unit warehouses and small manufacturing units to large multi-floor production facilities and multi-site operations.

Do you provide full certification and documentation for all work?

Yes. Every job is fully documented and certified to current regulations, including 18th Edition Wiring Regulations compliance. All reports are audit-ready and provided in a format suitable for your compliance records.

Which areas of London do you cover?

DB Site Services covers the whole of Greater London including Central London, East London, North London, North West London, South East London, South West London, and surrounding areas.
