I've been quoted ~£20k to connect into SPE network for main electric. £13k if digging myself. Note sure on their routing but its about 200m across a field or down a road to the nearest supply. I've contacted "Independent" Connection Providers and quotes are pending. At least one said don't bother with independents as they're not interested in single connections. Any toptips to reduce this? If not then off-grid solar is looking attractive.
