Changing the use of a commercial building is a significant moment in its lifecycle. Whether a space is being reconfigured, refurbished or repurposed entirely, the demands placed on its electrical systems can change considerably. For commercial landlords, this makes electrical safety a priority consideration during any change of use.
A new Electrical Installation Condition Report is often essential in these circumstances. It ensures that existing electrical installations remain safe, suitable, and compliant with the building’s new purpose.
Change of use occurs when a building is adapted for a different function from its previous occupation. This may involve a formal planning change or a practical shift in how the space is operated.
Common examples include offices being converted to laboratories, industrial units repurposed as workspaces, or buildings reconfigured into multi-let accommodation. Each scenario introduces different patterns of electrical demand, occupancy levels and operational risk.
Electrical systems designed for one use may no longer be appropriate for another. Reassessment is, therefore, a sensible and responsible step.
Commercial landlords have a duty to ensure that fixed electrical installations are safe and suitable for their intended use. This obligation does not end when a tenant vacates or when refurbishment begins.
When a building changes use, landlords are expected to consider whether existing electrical systems remain adequate. Failing to reassess electrical safety can expose occupants to risk and landlords to legal and insurance issues.
Maintaining electrical safety in commercial buildings is a continuous responsibility.
An EICR provides an objective assessment of the condition of fixed electrical installations. During a change of use, it helps determine whether systems designed for a previous function remain safe under new operating conditions.
The inspection identifies defects, capacity limitations and areas where systems may not meet current standards. This insight allows landlords to address issues before occupation, rather than responding to problems after the space is in use.
Professional Commercial EICR Testing (Electrical Installation Condition Report) supports informed decision-making during building transitions.
A change of use often brings increased electrical demand. New equipment, higher occupancy or extended operating hours can place additional strain on existing infrastructure.
Without reassessment, systems may be at risk of overload, premature failure or unsafe operation. An EICR helps confirm whether distribution boards, cabling and protective devices are suitable for the new load profile.
Addressing capacity issues early reduces the likelihood of disruption and unplanned expenditure later.
Certain change of use scenarios are particularly likely to require a new EICR.
Office to laboratory conversions typically introduce specialist equipment and higher power requirements. Industrial to office conversions may involve systems not originally designed for continuous occupation. Retail or warehouse spaces converted into offices often require significant reconfiguration of electrical layouts.
In multi-let buildings, subdivision of space can also alter how electrical systems are used and maintained, increasing the need for reassessment.
Refurbishment works are often undertaken alongside a change of use. Electrical alterations made during fit-out should always be followed by appropriate inspection and certification.
Integrating EICR inspections into commercial fit-out and refurbishment programmes helps ensure compliance is addressed alongside design and build activities.
This approach reduces delays, supports smoother project delivery and provides confidence at handover.
Up-to-date electrical documentation is essential during and after a change of use. Landlords should retain current EICRs, certificates for any electrical works and records of remedial actions.
Clear documentation supports insurance requirements, audit processes and future property transactions. It also provides reassurance to incoming tenants that electrical safety has been appropriately considered.
Electrical safety plays an essential role in tenant wellbeing and confidence. When systems are assessed and updated before occupation, tenants are less likely to experience disruption, faults or safety concerns.
Demonstrating a proactive approach to compliance supports professional landlord standards and helps establish positive landlord tenant relationships from the outset.
EICR findings gathered during a change of use can inform longer-term maintenance planning. Identifying emerging issues early enables landlords to integrate improvements into planned preventive maintenance programmes.
This reduces reliance on reactive repairs and supports consistent standards across property portfolios.
COEL supports commercial landlords throughout the change of use process, providing professional EICR inspections, clear reporting and practical guidance. Our experience across offices, laboratories and complex commercial environments ensures electrical systems are assessed with their intended use in mind.
By working with COEL, landlords can manage electrical obligations, support safe occupation, and protect the long-term performance of their buildings.
