Respecting our history

We began as Dennis Johns Electrical in Hackney almost 50 years ago. From these beginnings we have evolved and are now proud to be working in partnership with the Commercial and Public Sector, including Local Authorities, Education, Hospitality, Facilities, High Risk Business, Medical Facilities and Critical Environments.

Building our teams

We have a lot to be proud of and we never forget that we are only as good as our team. That is why, from the beginning, we wanted to ‘give something back’ to our communities by welcoming apprenticeships, providing in-house training and ensuring our workforce is highly qualified and certificated. We have expanded this by supporting an initiative encouraging more women to train in the electrical sector. We believe in equality, diversity and environmental policies and procedures. We are passionate about compliance and key performance indicators. Not just because of our partnership work with local authorities, but because residents and end-users are entitled to the highest level of competitive service.
