Electrical Design & Consultation

At Jumba Engineering Services Limited (Jumba Engineering.), we believe that great projects begin with great designs. For over 40 years, we have provided comprehensive electrical design and consultation services for commercial, industrial, residential, and institutional projects across Kenya. Our goal is to ensure that every system we design is safe, efficient, compliant, and future-ready.

With a team of registered Professional Engineers (PEs) under the Engineers Board of Kenya (EBK), and accreditation from EPRA (Class A1) and NCA1, we provide not only technical expertise but also the assurance of compliance with both Kenyan and international engineering standards.
