What Does Commercial Electrical Compliance Include?

Commercial electrical compliance in the UK typically includes EICR testing of fixed wiring installations (required every five years), emergency lighting testing and certification under BS 5266, portable appliance testing (PAT) under the Electricity at Work Regulations 1989, and fire alarm testing and certification under BS 5839-1. All commercial and industrial premises have a legal duty to maintain safe electrical installations and fire safety systems.

Commercial compliance is one of the fastest-growing areas of our work at Manchester Compliance. As a result, we’re now delivering full electrical and fire safety packages to small commercial and industrial units right across Greater Manchester — from medical supplies factories and food production units to trade workshops, offices, and warehouses.

In this article, we explain exactly how we handle emergency lighting, PAT testing, EICRs, and fire alarm testing for commercial and industrial clients, and why getting it right matters.

Commercial Compliance: Why It Matters for Every Business

Every commercial and industrial premises in the UK has a legal duty to maintain safe electrical installations and fire safety systems. Furthermore, the Regulatory Reform (Fire Safety) Order 2005 and the Electricity at Work Regulations 1989 both place clear obligations on the “responsible person” — typically the business owner, landlord, or facilities manager.

Failing to comply doesn’t just put people at risk. It can lead to enforcement action, insurance claims being rejected, and in serious cases, criminal prosecution. Consequently, having a trusted compliance partner who can cover all your testing under one roof is essential.

That’s exactly what we do at Manchester Compliance. Here’s how we approach each service.

EICR Testing for Commercial and Industrial Units

An Electrical Installation Condition Report (EICR) is a thorough inspection of the fixed wiring in a building. For commercial premises, this is legally required at least every 5 years, or more frequently depending on the type of premises and its use.

During a commercial EICR, our engineers inspect and test:

• Distribution boards and consumer units — checking for correct labelling, RCD protection, and signs of overheating
• Fixed wiring — testing insulation resistance, earth fault loop impedance, and continuity across all circuits
• Socket outlets and lighting circuits — verifying correct polarity, earth connections, and safe operation
• Three-phase supplies — many industrial units run on three-phase power, which requires specialist testing equipment and qualified engineers
• External installations — outdoor lighting, yard supplies, and loading bay electrics

In addition, we regularly carry out EICRs on factory floors, production areas, server rooms, and warehouse spaces where conditions can be harsh. Our engineers are experienced in working around machinery, production lines, and sensitive equipment without causing downtime. We covered the importance of ongoing EICR training and CPD in a recent blog post.

Emergency Lighting Testing and Certification

Emergency lighting is a legal requirement in virtually all commercial and industrial premises. Specifically, BS 5266-1 sets out the requirements for the installation, testing, and maintenance of emergency lighting systems.

There are two types of routine testing that every business needs:

Monthly Functional Tests

Every month, each emergency light fitting must be tested to confirm it illuminates when the mains supply is interrupted. This is a brief test — typically just a few seconds — to check the lamp operates on battery backup. We record the results and flag any fittings that fail.

Annual Full Duration Tests

Once a year, every emergency light must run for its full rated duration — usually 3 hours — to prove the battery can sustain illumination for the required period. This is a more involved test, and we schedule it carefully to minimise disruption to the business.

After completing the annual test, we issue a full emergency lighting certificate confirming compliance with BS 5266. In particular, we check escape routes, exit signs, open areas, high-risk task areas, and stairwells to make sure every part of the building is properly covered.

PAT Testing for Commercial Premises

Portable Appliance Testing (PAT) is the inspection and testing of all portable electrical equipment in a workplace. Although there’s no single law that says “you must PAT test,” the Electricity at Work Regulations 1989 require employers to maintain all electrical equipment in a safe condition — and PAT testing is the recognised way to demonstrate this.

For commercial and industrial units, we typically PAT test:

• Office equipment — computers, monitors, printers, kettles, phone chargers
• Workshop tools — power drills, grinders, sanders, soldering stations
• Kitchen and welfare equipment — microwaves, fridges, toasters, vending machines
• Production equipment — portable testing rigs, handheld tools, extension leads
• Site equipment — 110V transformers, cable reels, temporary lighting

Each item is visually inspected and then electrically tested using calibrated PAT testing equipment. We apply pass/fail labels to every item and provide a full register of all tested appliances. As a result, you have a clear audit trail that satisfies your insurance company, your HSE obligations, and any client or contractor audits.

Fire Alarm Testing and Certification

A working fire alarm system is one of the most critical safety measures in any commercial or industrial building. Similarly to emergency lighting, fire alarm systems must be regularly tested and maintained to comply with BS 5839-1.

Our fire alarm testing service covers:

Weekly Alarm Tests

A different call point should be tested each week on a rotating basis, with the results logged. Many businesses handle this themselves, but we can take it off your hands as part of a regular maintenance contract.

Quarterly and Annual Inspections

Every quarter, the system should receive a more detailed inspection. The full annual inspection includes testing every detector, call point, sounder, and the control panel. We check battery backup, zone configurations, fault logs, and system integrity. After the annual inspection, we issue a fire alarm certificate confirming the system meets current standards.

For industrial units, we pay particular attention to detector types — making sure heat detectors are used in dusty or steamy environments where smoke detectors would false alarm, and that beam detectors or aspirating systems are correctly positioned in large open spaces like warehouses and factory floors.

How Manchester Compliance Delivers Commercial Compliance

What sets us apart is the way we package everything together. Instead of dealing with multiple contractors for your EICR, emergency lighting, PAT testing, and fire alarms, we deliver the full package under one roof.

Here’s how it works in practice:

• Single point of contact — one account manager coordinates everything, so you’re not chasing multiple contractors
• Flexible scheduling — we work around your operating hours, including evenings, weekends, and shutdown periods. We were at a medical supplies factory this Saturday morning, for example
• Fully qualified engineers — every engineer on our team is NICEIC qualified, and we invest heavily in ongoing training and CPD
• Fast turnaround on certificates — we use the latest digital certification software to deliver certificates quickly and accurately
• Competitive pricing — bundling services together means better value for the client

We’ve delivered commercial compliance packages for a wide range of premises, including:

• Medical and pharmaceutical factories
• Food production and packaging units
• Engineering and fabrication workshops
• Trade counters and retail units
• Office blocks and serviced offices
• Warehouses and distribution centres
• Gyms, salons, and leisure facilities
• Pubs, restaurants, and takeaways

Regardless of the size or type of unit, the approach is the same — thorough, professional, and fully documented. Our commitment to customer service means we keep you informed at every stage and make the process as painless as possible.

Common Issues We Find in Commercial Units

Over the years, we’ve seen the same problems come up time and again in commercial and industrial premises. Here are some of the most common:

• Outdated distribution boards — many older commercial units still have boards with no RCD protection, which is a serious safety risk
• Non-fire-rated downlights — a hidden fire risk we regularly flag during EICRs, especially in suspended ceilings
• Failed emergency lighting batteries — batteries degrade over time, and many businesses don’t realise their emergency lights won’t last the required 3 hours until we test them
• Missing PAT labels — equipment that hasn’t been tested in years, creating a liability for the business
• Fire alarm faults left unresolved — fault conditions on fire panels that have been silenced rather than investigated and fixed

Therefore, regular testing isn’t just a box-ticking exercise. It genuinely saves lives and protects your business.
