COMMERCIAL ELECTRICAL SURVEYS & ENGINEERING ASSESSMENTS
An Electrical Infrastructure Survey provides a detailed understanding of the condition, capability and limitations of an existing commercial or industrial electrical system.
Unlike a standard condition report, the survey considers whether the infrastructure can support the way the building is used today, proposed future demand and any planned redevelopment or expansion.
✓ Review of incoming electrical supplies and available capacity.
✓ Inspection of main switchgear and distribution infrastructure.
✓ Assessment of ageing electrical assets and equipment condition.
✓ Review of network configuration and electrical resilience.
✓ Identification of single points of failure.
✓ Electrical load monitoring and data logging.
✓ Analysis of peak demand, diversity and operating patterns.
✓ Assessment of available spare capacity.
✓ Review of circuit schedules, drawings and existing documentation.
✓ Identification of constraints affecting future development.
✓ Options appraisal for infrastructure upgrades.
✓ Prioritised engineering recommendations and investment planning.
01
A structured assessment of the existing electrical network, including incoming supplies, switchgear, distribution equipment, critical assets and supporting documentation.
02
Specialist data loggers record actual electrical demand over an agreed period, providing evidence of peak loading, diversity, operating patterns and spare capacity.
03
Existing demand is assessed against proposed future loads to establish whether the current infrastructure can support expansion, redevelopment or additional equipment.
04
Main switchgear and distribution equipment are assessed for condition, age, maintainability, operational risk and remaining suitability.
05
The infrastructure is reviewed for single points of failure, limited redundancy, critical-load dependencies and operational vulnerabilities.
06
Where limitations are identified, Whitton Electrical provides practical infrastructure options, priorities and recommendations to support future design and investment decisions.
CAPACITY, CONDITION & FUTURE DEVELOPMENT
Many organisations make significant investment decisions without fully understanding the capability of their existing electrical infrastructure.
Engineering surveys provide the evidence required to reduce risk, plan investment and determine whether the existing network can support future development.
✓ Unknown electrical capacity available within the existing network.
✓ Existing infrastructure unable to support future expansion.
✓ Ageing switchgear approaching replacement.
✓ Limited electrical resilience creating operational risks.
✓ No electrical load monitoring or historical demand data.
✓ Unknown diversity and peak-loading characteristics.
✓ Inadequate provision for additional tenants or equipment.
✓ Existing infrastructure lacking flexibility for redevelopment.
✓ Electrical documentation no longer reflecting the current installation.
✓ Investment decisions being made without engineering evidence.

COMMERCIAL ELECTRICAL SURVEY CASE STUDY
Ladywood House, Portsmouth
The client needed to establish whether the existing electrical installation at Ladywood House could support future redevelopment and increased building demand.
Before progressing with the next stage of the project, they required a clear understanding of the condition, resilience and available capacity of the existing electrical network, together with practical engineering recommendations for future investment.
The survey needed to assess the existing LV distribution infrastructure, switchgear, electrical assets and wider power-distribution network. Whitton Electrical was asked to identify ageing equipment, operational risks, resilience limitations and potential constraints on future expansion.
Whitton Electrical carried out a comprehensive Electrical Infrastructure Assessment combining detailed site investigations, switchgear inspection, electrical load monitoring and engineering analysis.
Specialist data loggers were installed to record electrical demand over an extended period. This allowed actual operating loads, peak demand, diversity and available spare capacity to be measured rather than estimated from theoretical calculations.
Our engineers also completed a detailed condition assessment of the existing switchgear and distribution equipment, identifying ageing assets, operational risks and limitations within the existing network.
Using the measured data and survey findings, Whitton Electrical produced a detailed engineering report containing:
The completed survey gave the client a clear, evidence-based understanding of the condition, resilience and available capacity of the building’s electrical infrastructure.
The report provided a practical basis for future electrical design, redevelopment planning and investment decisions, allowing the client to progress with confidence that any infrastructure upgrades would be based on measured operational data and sound engineering principles.

Specialist load logging established actual operating demand, peak loads, diversity and available spare capacity.
The survey identified ageing assets, resilience limitations, operational risks and potential barriers to future redevelopment.
The final engineering report provided practical options for switchgear upgrades, infrastructure improvements and long-term asset planning.
An Electrical Infrastructure Survey is an engineering assessment of a building’s existing electrical network.
It considers the condition of the infrastructure, available capacity, electrical demand, resilience, maintainability and suitability for current or future use.
An EICR primarily assesses electrical safety and the condition of the fixed installation.
An electrical infrastructure survey has a wider planning purpose. It considers how the network operates, how much capacity is available, where resilience is limited and what upgrades may be required to support future demand.
The precise scope depends on the building and client objectives.
It may include incoming supplies, main switchgear, distribution boards, electrical assets, network configuration, existing drawings, load monitoring, capacity analysis, resilience assessment and upgrade options.
An electrical capacity assessment compares the demand already placed on an installation with the capability of the existing supply and distribution infrastructure.
It helps establish whether additional equipment, tenants or development can be supported without reinforcement or major upgrades.
Load monitoring records how the installation actually performs during normal operation.
It can reveal peak demand, diversity, spare capacity and operating patterns that may not be visible from drawings, equipment ratings or theoretical calculations alone.
The monitoring period depends on the way the site operates and the information required.
The logging period should be long enough to capture representative demand, peak operating conditions and relevant variations in building use.
Yes. As part of your electrical infrastructure survey, Whitton Electrical can review existing infrastructure against proposed future electrical demand and identify constraints, upgrade requirements and available options.
Yes. The condition, age, maintainability and operational limitations of existing switchgear can form an important part of the infrastructure survey.
Where further specialist investigation is required, this will be clearly identified in the report.
Where resilience forms part of the agreed scope, the survey can review critical supplies, network configuration, backup arrangements and dependencies that may create single points of failure.
Yes. The client receives a structured report explaining the survey findings, measured data, identified risks, capacity constraints and recommended options.
The report is written to support practical decision-making rather than simply recording technical observations.
Yes. Where the survey identifies required improvements, Whitton Electrical can support the subsequent design, installation, switchgear replacement, distribution upgrades, testing and commissioning.
The survey and any later installation works remain separately defined and scoped.
Yes. Site investigations and load monitoring can be planned around staff, tenants, production and other operational requirements.
Any access, isolation or disruption requirements will be discussed before work begins.
