All reports are provided digitally and stored in our system for easy access to historical records."}},{"@type":"Question","name":"What is included in your preventive maintenance programs?","acceptedAnswer":{"@type":"Answer","text":"

Our preventive maintenance programs include regular scheduled inspections, thermal imaging surveys, tightening of electrical connections, testing of protection devices, cleaning of panels and equipment, checking for signs of deterioration, testing emergency systems, updating documentation, and providing detailed reports with recommendations. Programs are customised based on your equipment and risk profile.

"}},{"@type":"Question","name":"What is included in your maintenance contracts?","acceptedAnswer":{"@type":"Answer","text":"

Our maintenance contracts include scheduled preventive inspections, thermographic surveys to detect hotspots, testing and certification as required, priority response for breakdowns, detailed reporting after each visit, recommendations for improvements, parts discounts, and dedicated account management. Maintenance contracts provide cost certainty and reduce unexpected breakdowns.

"}},{"@type":"Question","name":"What do you check during a preventive maintenance visit?","acceptedAnswer":{"@type":"Answer","text":"

During maintenance visits, we inspect electrical panels for signs of damage or deterioration, perform thermal imaging scans, test critical circuits and protective devices, check and tighten connections, verify proper operation of control systems, test emergency systems, review and update documentation, identify potential issues before they cause failures, and provide comprehensive reports with photographs and recommendations.

"}},{"@type":"Question","name":"What is thermal imaging and why is it important for maintenance?","acceptedAnswer":{"@type":"Answer","text":"

Thermal imaging uses infrared cameras to detect temperature anomalies in electrical systems. Hot spots indicate loose connections, overloaded circuits, or failing components that aren't visible during normal inspections. Identifying these issues early prevents unexpected failures, reduces fire risk, and enables planned repairs during convenient maintenance windows. Thermal imaging is one of the most effective predictive maintenance tools available.

"}},{"@type":"Question","name":"How often should electrical systems be serviced?","acceptedAnswer":{"@type":"Answer","text":"

Electrical system maintenance frequency depends on the environment and criticality. Standard commercial facilities typically benefit from annual maintenance, while industrial environments with harsh conditions may require quarterly or bi-annual visits. High-criticality systems like data centers or hospitals should be serviced more frequently. We assess your specific needs and recommend appropriate maintenance intervals.

"}},{"@type":"Question","name":"How does preventive maintenance reduce downtime?","acceptedAnswer":{"@type":"Answer","text":"Preventive maintenance reduces downtime by identifying and correcting small issues before they become major failures, maintaining equipment in optimal condition, extending equipment life, ensuring protection devices function correctly, maintaining compliance and safety, and providing you with advance warning of components that may need replacement. This proactive approach is far more cost-effective than reactive repairs."}},{"@type":"Question","name":"What affects the cost of preventive electrical maintenance?","acceptedAnswer":{"@type":"Answer","text":"

Maintenance costs are influenced by site size and equipment quantity, equipment age and condition, frequency of visits required (quarterly, bi-annual, annual), complexity of systems (standard distribution vs. specialized equipment), access requirements and site restrictions, and compliance testing needs. We offer tailored maintenance packages that provide better value than ad-hoc reactive callouts.

"}},{"@type":"Question","name":"Do you offer FIRETRACE systems?","acceptedAnswer":{"@type":"Answer","text":"

Yes, we can install FIRETRACE systems within control panels and LV distribution equipment, providing automatic fire detection and suppression directly at the source to protect critical electrical infrastructure and reduce the risk of fire-related downtime.

    Comprehensive Preventive Maintenance Expertise

    For over 40 years, we've been helping UK manufacturers avoid costly breakdowns through systematic preventive maintenance. Our programmes cover everything from routine inspections to thermal imaging surveys and detailed testing protocols.

    Electrical Testing

    Regular inspection and testing of control panels, distribution boards, motors, and critical electrical infrastructure to BSEN60204-1 standards.

    Thermal Imaging

    Advanced infrared surveys detect hot spots, loose connections, and failing components before they cause failures or fire hazards.

    Maintenance Records

    Detailed service reports, test results, and photographic evidence create a complete maintenance history for compliance audits.

    The True Cost of Reactive Maintenance

    Equipment failures rarely announce themselves in advance. When electrical systems fail unexpectedly, the consequences cascade through your operation—production stops, emergency callout fees mount, related equipment gets damaged, and your team scrambles under pressure to restore operations.

    Challenges illustration

    Emergency Callout Costs

    Out-of-hours emergency repairs cost significantly more than scheduled maintenance visits, with premium rates for urgent response and parts.

    Production Downtime

    Unplanned stoppages disrupt production schedules, delay customer orders, and create rushed recovery situations that compound stress and costs.

    Cascading Failures

    One failing component often damages related equipment, turning a simple repair into a major system rebuild with extended downtime.

    Safety Incidents

    Poorly maintained electrical systems increase risks of shock hazards, arc flash incidents, and fire dangers that threaten personnel and facilities.

    Premature Replacements

    Equipment that isn't properly maintained fails earlier than its design life, forcing expensive replacements years before necessary.
