Does a right by deed to a supply of electricity over neighbouring land which includes a right to ‘repair, renew, maintain, inspect, replace and cleanse’ electrical pipes, wires and cables include a right to ‘upgrade’ a single phase supply to a three phase supply involving a replacement ‘transformer’ and ‘cables’ and an additional ‘pole’ to support the transformer or can the neighbour argue that these works would be beyond the original grant? This is where the existing supply is not ‘out of repair’ but is at the limit of its capacity. Can the ‘upgrade’ also include provision for future changes such as electrical heating pumps and car charging?
