What our clients say...

  • We asked Connectus Electrical to carry out the design and install for the new electrical supplies to our equipment for our new robotic cell manufacturing unit.  We were on a very tight schedule and with the help Connectus Electrical’s team, the project was operational on time.

  • We have had a long standing relationship with Connectus Electrical Ltd based on excellent service and competitive pricing. Following a weekend flood that damaged our offices, reception, and meeting rooms we called out Connectus who had temporary power set up ready for Monday morning that minimised any business disruption. Connectus subsequently carried out all electrical repairs, rewiring, and data services; we were delighted with the standard of works and the way in which their team carried them out.
