Electrical Maintenance Contracts for Commercial Properties: What's Included?

If you manage or own a commercial property, you already know there's a long list of things that need regular attention. Electrical systems sit near the top of that list — not because they cause problems every day, but because when they do go wrong, the consequences are serious. A commercial electrical maintenance contract is the practical way to stay on top of it without waiting for something to fail.

This post explains exactly what these contracts typically cover, what you should expect from a reputable contractor, and how to judge whether what you're being offered is actually fit for purpose.

What Is a Commercial Electrical Maintenance Contract?

A commercial electrical maintenance contract is a formal agreement between a business or property manager and a qualified electrical contractor. It sets out what electrical work will be carried out on a scheduled basis, how often, and at what cost.

These contracts suit a wide range of premises — offices, retail units, warehouses, schools, care homes, industrial units, and multi-tenanted buildings. Anywhere that has staff, customers, or tenants relying on electrical systems to function safely and reliably.

The contract creates a structured, documented maintenance programme rather than a reactive one. Instead of calling someone out when the lights fail or a circuit trips, you have a plan in place.

What's Typically Included?

The exact scope varies depending on your property, but most well-structured contracts will cover the following.

Fixed Wire Testing (EICR)

An Electrical Installation Condition Report — commonly called an EICR — is a formal inspection of your fixed electrical installation. It checks the condition of wiring, distribution boards, protective devices, earthing, and bonding against the requirements of BS 7671 (the IET Wiring Regulations).

For commercial premises, EICRs are typically required every five years, though higher-risk environments such as industrial sites or properties with older wiring may need them more frequently. Some contracts bundle the EICR into the annual cost; others price it separately. Either way, it should be clearly included.

If you're a landlord with commercial tenants, keeping a valid EICR is increasingly expected as standard — and in some sectors, it's a condition of your insurance policy.

Portable Appliance Testing (PAT)

PAT testing covers electrical equipment that can be moved and plugged in — laptops, monitors, kettles, extension leads, power tools, and so on. The frequency depends on the type of equipment and how it's used.

A good maintenance contract will include a documented PAT schedule with clear records of what was tested, the outcome, and when the next test is due. This matters if you ever need to demonstrate due diligence following an incident.

Emergency Lighting Testing

If your premises require emergency lighting — and most commercial buildings do — regular testing is a legal requirement under BS 5266. Monthly function tests and an annual full-duration discharge test should be documented and kept on record.

Emergency lighting is often overlooked until a fire risk assessment flags it as a deficiency. Having it built into a maintenance contract means it gets done consistently.

Distribution Board Inspections

Your distribution boards (consumer units / fuse boards in commercial terms) should be inspected periodically to check for signs of overloading, overheating, loose connections, or outdated protective devices. Older boards with rewirable fuses or non-RCD-protected circuits present a higher risk and may flag remedial work.

Reactive Call-Out Cover

Many commercial electrical maintenance contracts include a call-out provision — usually a set number of hours per year, or a guaranteed response time. This is worth scrutinising. Check whether call-out rates are discounted for contract clients, what the response time guarantee is, and whether out-of-hours cover is available.

For businesses in areas like Bromley, Maidstone, or across the M25 corridor, having a contractor who can reach you quickly matters. A contract that promises 24-hour response but relies on a one-person team isn't much use.

Thermographic Surveys

Not always standard, but increasingly common in larger contracts or more complex installations. Thermal imaging identifies hot spots in electrical panels and connections before they become failures. It's non-invasive and can be carried out while systems are live. If your property has a significant electrical load or older infrastructure, it's worth asking whether this is offered.

What Should a Contract Cost?

This varies considerably depending on the size of your premises, the complexity of your installation, and what's included. A basic contract for a small office covering an EICR, PAT testing, and emergency lighting checks might come in at £400–£900 per year. A larger site with multiple distribution boards, extensive portable appliance inventory, and reactive call-out cover could run to several thousand pounds annually.

Be cautious of contracts priced very low. If an EICR alone for a commercial property typically costs £300–£600, a contract priced at £200 per year for everything is either incomplete or cutting corners somewhere.

Always ask for a written scope of works — what's included, what's excluded, and how additional work is priced. This protects you and the contractor.

Regulations and Compliance: What Applies to You?

Commercial premises in England are subject to several overlapping regulatory frameworks:

• BS 7671:2018+A2:2022 — the current IET Wiring Regulations, which all electrical installation work must comply with
• The Electricity at Work Regulations 1989 — places a duty on employers to ensure electrical systems are maintained to prevent danger
• The Health and Safety at Work Act 1974 — broad duty of care that encompasses electrical safety
• Fire safety legislation — ties into emergency lighting and fire alarm systems

Part P of the Building Regulations applies specifically to domestic premises, so it doesn't govern commercial electrical work directly — but any building work with an electrical component on a commercial site still requires the work to be carried out to a compliant standard and notified where required.

Working with a NICEIC-approved contractor gives you documented assurance that the work is carried out to the required standard. NICEIC approval involves regular audited inspections of contractors' work — it's not a rubber stamp, it's an ongoing assessment process.

When to Call a Qualified Electrician

Outside of your scheduled maintenance visits, there are circumstances where you should call a qualified electrician promptly rather than waiting:

• Circuit breakers or RCDs tripping repeatedly
• Burning smells or scorch marks around sockets, panels, or equipment
• Flickering or intermittent power in part of the building
• Any electrical installation that hasn't been tested within the last five years
• Before taking on a new commercial tenancy or purchasing a commercial property
• After flooding or water ingress near electrical systems

None of these should be left and monitored. If you're in Kent, Surrey, Essex, or elsewhere across the South East, a qualified, NICEIC-approved contractor should be your first call — not an emergency general maintenance team.

Choosing the Right Contractor

When evaluating contractors for a commercial electrical maintenance contract, look for:

• NICEIC approval (check the register at niceic.com)
• Clear documentation provided after every visit
• A written contract with a defined scope
• Experience with your type of premises
• References or case studies from similar commercial clients
• Transparent pricing with no ambiguous call-out terms

Don't just go with whoever is cheapest. Electrical maintenance is one of those areas where cutting costs can have genuinely serious consequences.
