Free tool · Grid connections
Who runs your grid? Find out in one click.
Enter your UK postcode and we'll tell you which Distribution Network Operator (DNO) you're connected to, how to report a power cut, and where to check available capacity for new generation.
Why it matters
Every solar, battery, or EV-charging project needs sign-off from your DNO. Knowing them up-front saves weeks.
What we don't do
We don't store your postcode unless you ask us for a feasibility check. The lookup runs the moment you click.
Power cut?
Across mainland UK the emergency line is 105 — free from any phone. Northern Ireland uses NIE Networks.
