For many contractors, a project ends at handover. At Jumba Engineering Services Ltd. (Jumba Engineering.), we believe that is where true responsibility begins. Electrical and infrastructure systems require ongoing maintenance, monitoring, and client support to remain safe and efficient.

This philosophy led to the creation of the Jumba Care Program — a comprehensive after-sales service that combines preventive maintenance, emergency support, and financing solutions. With over 40 years in Kenya’s engineering industry, we have seen how proactive care saves clients from costly breakdowns and improves system reliability.

Why Maintenance Matters

Electrical and infrastructure systems degrade over time due to:

  • Wear and tear on transformers, breakers, and cables.

  • Environmental factors (humidity, dust, corrosion).

  • Power quality issues (harmonics, surges).

  • Poor or irregular inspections.

Consequences of neglect include:

  • Fire hazards.

  • Unexpected blackouts.

  • Costly equipment replacements.

  • Business downtime and financial losses.

Globally, studies show that preventive maintenance costs up to 5× less than corrective repairs.

What the Jumba Care Program Covers

  1. Preventive Maintenance

    • Scheduled inspections of LV/MV boards, transformers, solar inverters, and UPS systems.

    • Thermal imaging to detect hotspots before failures.

    • Earthing resistance testing and reinstatement.

  2. Corrective Maintenance

    • Rapid response teams for breakdowns.

    • 24/7 emergency callout services.

    • Replacement of faulty components with certified spares.

  3. Performance Monitoring

    • Load profiling and energy audits.

    • Power factor correction to reduce penalties.

    • Continuous improvement reports to clients.

  4. Client Training

    • Hands-on training for facility managers.

    • Safety workshops in line with OSHA Kenya and ISO 45001.

  5. Flexible Financing

    • Partnerships with Equity Bank, KCB, Co-op Bank, and DBK.

    • Clients can access loans to upgrade or maintain systems.

    • Pay-as-you-go models for SMEs adopting solar or backup systems.

Case Study: Garden City Mall Annual Testing

Jumba Engineering has been retained under a Jumba Care contract for annual transformer, LV board, and RMU testing at Garden City Mall.

Our Actions:

  • Full load testing, relay calibration, and transformer oil analysis.

  • Earthing tests and re-bonding of oxidized conductors.

  • Preventive maintenance on high-bay lighting and emergency systems.

Impact:

  • Reduced downtime incidents by 80%.

  • Extended transformer life by an estimated 10 years.

  • Provided mall management with detailed annual QA reports.

How Clients Benefit from Jumba Care

  • Peace of mind: Systems monitored and maintained by professionals.

  • Cost savings: Preventive action avoids expensive emergencies.

  • Compliance: Satisfies EPRA, OSHA, and insurance requirements.

  • Extended lifespan: Equipment serves longer with less failure.

  • 24/7 support: Access to Jumba Engineering’s skilled engineers any time.

Our Care Philosophy

The Jumba Care Program reflects our belief that engineering is not just about building systems — it’s about building relationships with clients. By standing with our clients after project completion, we:

  • Reduce stress for facility owners.

  • Improve safety for workers and tenants.

  • Build loyalty through consistent performance.

As Eng. Vincent Ben Jumba often emphasizes: “The mark of a true engineer is not just in the design but in the stewardship of what we build.”

Conclusion

The Jumba Care Program is more than maintenance — it’s a promise. A promise that Jumba Engineering will continue to walk with you, long after your systems are commissioned. Through preventive care, rapid response, and financing support, we ensure your systems remain safe, efficient, and future-ready.
