Service alterations 

We are often asked by customers, commercial developers and electricians to move an electricity supply, and our engineers are always busy making alterations to the system as a result of building work.
However, service alterations to the electricity supply require planning and processes to ensure minimum disruption and safe provision of adequate voltage levels.
