For an existing inspection schedule, identify the asset population and records required. Select RCD testing, emergency lighting testing or thermal imaging, with access and follow-up responsibilities agreed before attendance.
For recurring faults or several sites, start with a commercial electrical maintenance program. Separate planned visits from reactive requests and define the response targets, reporting and approval process for your facilities.
For alterations, provide the equipment requirements, room layout and existing infrastructure information. Coordinate electrical work with communications and AV requirements so power, data and installed technology are considered together.
Send the site address, building use, scope, timing and any previous reports or photographs. Include known access restrictions and the people responsible for approvals. Our school testing case studies show examples of recorded findings and follow-up.
They can be scoped together where appropriate. Agree which repairs may proceed during the visit and which require a quotation, additional parts or a separate shutdown. Keep inspection outcomes and completed repairs clearly recorded.

Inspection and testing of residual current devices to identify protection devices that fail to operate correctly or require further investigation.
Testing of emergency and exit-light assets with defective fittings, batteries and associated issues recorded for rectification.
Visual inspection, electrical testing, tagging and asset recording for suitable portable electrical equipment in commercial and public facilities.
Infrared inspection of suitable electrical boards and components to identify unusual heat patterns that may indicate a developing electrical issue.
Interior, exterior, security and feature-lighting installation, repairs, replacements and practical lighting upgrades.
New outlets, dedicated equipment circuits, relocations, repairs and electrical additions supporting changing operational requirements.
Visual inspections, minor works, circuit identification, labelling, defect reporting and planning for required switchboard upgrades.
Investigation of lighting, power, circuit and equipment-supply faults followed by clear repair or rectification recommendations.
Planned inspection and maintenance intended to identify defects early and reduce avoidable electrical disruption.

Electrical testing is most useful when the results are clear and actionable. Our team can inspect the agreed assets, record identified defects and provide information to support rectification and future maintenance planning.
Testing intervals and scope should be determined according to the site, equipment type, operating environment, risk assessment and applicable requirements.
Test residual current devices and identify units that fail to operate correctly or require further electrical investigation.
Inspect and test installed emergency-lighting assets and record defective fittings, batteries or related issues.
Inspect and test suitable portable electrical equipment with asset identification and records appropriate to the agreed scope.
Scan suitable electrical components under appropriate conditions to identify abnormal heat patterns requiring further assessment.
From a new outlet or circuit through to coordinated electrical work for a workplace, classroom, venue or technology upgrade, our team considers access, equipment requirements, room use and future support.
New lighting, replacement fittings, lighting modifications, controls, security lighting and practical efficiency upgrades.
Power outlets, dedicated circuits, equipment supplies, relocation works and infrastructure for new commercial equipment.
Electrical additions, moves and changes for workstations, offices, classrooms, training spaces and operational areas.
Minor switchboard modifications, circuit protection, identification, labelling and planning for required infrastructure upgrades.
Electrical infrastructure for meeting rooms, displays, projectors, equipment racks, digital signage and communications systems.
Electrical work coordinated with structured cabling, equipment installation and commercial AV integration.
A structured electrical maintenance programme helps facility teams understand their assets, prioritise defects and plan corrective work before minor issues become operational disruptions.
Confirm sites, assets, operating conditions and the required electrical scope.
Establish attendance timing, access, site contacts and disruption controls.
Complete the agreed inspections, tests and maintenance activities.
Record completed activities, tested assets and identified defects.
Complete approved repairs, replacements or further investigation.
Schedule the next attendance based on the agreed maintenance programme.
Different facilities have different access requirements, operating hours, disruption risks and stakeholder expectations. Our work is planned around the environment rather than treated as a generic installation.
