Our infrastructure supplies power to homes and businesses across the north of Scotland, central southern England, and at a smaller number of locations across the rest of the United Kingdom where we have ‘National Networks’ embedded within other Distribution Network Operator licence areas. Our networks consist of overhead lines, underground cables, and other connected equipment that can be situated both above and below ground. 

From time to time the development and maintenance work of others can come close to, and often cross, our infrastructure. For example, road works to improve road layout or add extra lanes typically also involve work to move electricity lines or cables. It’s therefore important we ensure the safety of those carrying out these works and facilitate an efficient system to give advice on working in proximity to our equipment and quotations for moving our equipment and other services to facilitate clients’ projects if required.
