Moving into a commercial property involves more than checking its size, layout and location. The existing electrical installation also needs to be suitable for your business and the equipment you plan to use.
This guide covers the key electrical checks before moving into a commercial property, including the installation’s condition, EICR records, electrical capacity, distribution boards and future requirements.
What Should You Check Before Moving Into a Commercial Property?
Before moving in, check the condition of the existing electrical installation, available records, power capacity, distribution boards and any equipment your business plans to use.
Check the Existing Electrical Installation
Electrical installations in workplaces should be properly maintained to prevent danger. The Health and Safety Executive (HSE) guidance on electricity at work provides further information on maintaining electrical systems and equipment safely.
Start by understanding what electrical systems are already installed in the property. This may include:
- Distribution boards and consumer units
- Fixed wiring and electrical circuits
- Socket outlets and fixed equipment connections
- Internal and external lighting
- Emergency lighting
- Earthing and bonding arrangements
- Single-phase or three-phase supplies
- Electrical equipment and dedicated circuits
Look for visible signs of damage, overheating, exposed wiring, damaged accessories or poorly labelled circuits.
A visual check can identify obvious problems, but it cannot confirm the overall condition of a fixed electrical installation. Where there are concerns, appropriate inspection and testing may be needed.
Review EICR and Electrical Records
Ask for the latest Electrical Installation Condition Report (EICR) and any available records of previous electrical work.
Check:
- When the installation was last inspected
- The overall outcome of the inspection
- Any observations or classification codes
- Whether recommended remedial work was completed
- Records of previous alterations or additions
- Any limitations noted during the inspection
An EICR provides useful information about the condition of the fixed electrical installation, but the report should be considered alongside your business’s intended use of the property.
For rented commercial premises, responsibilities for electrical work can also depend on the lease and the arrangements between the landlord and tenant.
Check Electrical Supply and Available Capacity
A property may have electricity available without having enough capacity for your business.
Consider the electrical demand of equipment such as:
- Commercial ovens and cooking equipment
- Refrigeration systems
- Air conditioning
- Machinery and compressors
- Computers and servers
- Workshop equipment
- Production equipment
- EV chargers
You should also understand whether the property has a single-phase or three-phase supply and whether the existing distribution system can support the expected demand.
Having a three-phase supply does not automatically mean that sufficient capacity is available. Where demand is expected to increase, an electrical load assessment can help determine whether an upgrade is required.

Check Distribution Boards and Circuit Protection
Distribution boards control and distribute electrical power to different circuits throughout the property.
Before moving in, check whether:
- Circuits are clearly identified
- Protective devices are suitable for the circuits
- Distribution boards show signs of damage or overheating
- Existing circuits are adequately documented
- Additional circuits may be required
- There is suitable capacity for planned electrical work
An unused space in a distribution board does not automatically mean that another circuit can be added safely. The existing installation, protective arrangements and available capacity all need to be considered.
Make Sure the Electrical System Can Support Your Equipment
Your electrical requirements depend heavily on what your business does.
An office may need power for computers, servers, printers, kitchen equipment and air conditioning.
A retail unit may require power for display lighting, refrigeration, tills, security systems and signage.
A restaurant can have much higher demand from ovens, refrigeration, extraction systems, dishwashers and other kitchen equipment.
Warehouses and workshops may require supplies for machinery, compressors, battery chargers, high-level lighting and other equipment.
Understanding these requirements before moving in helps identify whether additional circuits, distribution changes or increased electrical capacity may be needed.
Check Emergency Lighting and Other Safety Systems
If the property already has emergency lighting, check its condition and available inspection or maintenance records.
Consider whether the existing system remains suitable if you are changing:
- Internal layouts
- Escape routes
- Partitions
- Occupancy levels
- Working areas
- Access routes
Changes to how a building is used can affect its electrical and life-safety requirements. Existing systems should not automatically be assumed to remain suitable after significant alterations.
Look for Previous Electrical Alterations
Commercial properties are often modified by previous occupiers.
Previous electrical work may include additional:
- Socket outlets
- Lighting
- Machinery circuits
- Kitchen equipment
- Air conditioning supplies
- Signage
- Distribution boards
- Dedicated equipment supplies
Try to establish what has been added or changed and whether supporting documentation is available.
This can help you understand the existing installation before making further alterations.
Consider Your Future Electrical Requirements
Your electrical requirements may increase after you move in.
Think about possible future changes such as:
- Additional employees and workstations
- New machinery
- More refrigeration
- Additional air conditioning
- EV charging
- Kitchen equipment
- Production equipment
- New rooms or extensions
- Increased lighting requirements
Planning for future demand can help avoid repeated electrical modifications and unnecessary disruption to your business.
Who Is Responsible for Electrical Work in a Commercial Property?
If you are renting the property, check your lease before arranging electrical work.
Responsibilities may differ between the landlord and tenant depending on the terms of the agreement and the type of work involved.
Check who is responsible for:
- Electrical repairs
- Routine maintenance
- Testing and inspection
- Alterations and installations
- Upgrades
- Approval of electrical changes
- Costs associated with remedial work
Understanding these responsibilities before work begins can help prevent delays and unexpected costs.

When Should You Get a Commercial Electrician to Inspect the Property?
A professional assessment can be particularly useful when:
- The condition of the installation is unclear
- Electrical records are missing
- The latest EICR identifies issues
- The business will use high-demand equipment
- New machinery or specialist equipment is being installed
- The property has undergone previous alterations
- Additional circuits are required
- Electrical capacity may need to increase
- You are planning a commercial fit-out or refurbishment
The purpose is not necessarily to replace the entire electrical installation. A proper assessment can help identify what actually needs attention and what can remain in service.

FAQs
Do I need an EICR before moving into a commercial property?
Not every commercial property automatically requires a new EICR simply because a new business is moving in. The appropriate inspection and responsibilities depend on the property, existing records, lease arrangements and applicable requirements.
What should I look for in an EICR?
Check the inspection date, overall outcome, observations, classification codes, recommended remedial work and any limitations recorded in the report.
How can I tell if a commercial property has enough electrical capacity?
Start by identifying the existing electrical supply, distribution arrangements and the power requirements of your equipment. A competent electrician can assess the installation and determine whether additional capacity may be required.
Does an old commercial property always need rewiring?
No. The age of a property or electrical installation alone does not automatically mean that complete rewiring is required. Its condition, suitability, previous alterations and electrical requirements should be assessed.
Can I install my business equipment as soon as I move in?
Not necessarily. Some equipment may require dedicated circuits, suitable protection or additional electrical capacity. These requirements should be checked before installation.
Who pays for electrical work in a rented commercial property?
This depends on the lease and the type of electrical work required. Check your agreement to establish whether the landlord or tenant is responsible.
Conclusion
The electrical checks before moving into a commercial property can help you understand whether the existing installation is suitable for your business. Review its condition, electrical records, available capacity and planned equipment before starting operations.
