We are an approved Meter Operator (MOP) with over 20 years of experience supplying and installing isolators. 


An isolator switch can be fitted between your meter and fuse board, allowing connection or disconnection of your electricity supply without the need of a Distribution Network Operator, and ensuring the circuit is safe and de-energised to allow maintenance work to take place.   

Our Elexon accreditation enables us to provide and fit isolators without this third-party involvement, which can save our customers both valuable time and money.
