What We Do

We transmit, distribute and connect electricity to and from homes and businesses over our network. We work around the clock to keep the lights on 24 hours a day, every day of the year.

We serve 3.5 million homes and businesses in three of the UK's largest cities (Liverpool, Glasgow & Edinburgh), as well as three large rural areas (North Wales, Scottish Borders and Dumfries & Galloway).

We take electricity generated from power stations, wind farms and other utilities, reduce it to the low voltage needed for homes and transport it through our vast transmission network.

Our distribution network has 30,000 substations (1 for every 100 customers), 40,000km of overhead lines (that's once around the globe!) and 65,000km of underground cables.

We provide customers with new or upgraded connections to our network. These one-off connections are to large residential, retail and industrial developments, as well as sports stadia and leisure parks.

What We Don’t Do

We don't sell electricity and we don't issue electricity bills; that’s up to your electricity supplier.

A percentage of your bill payments comes to us for running, maintaining and investing in the electricity network in your area. OFGEM decides how much we can charge for the service we provide.

Regardless of who you buy your electricity from, contact us if there’s a problem with your supply. Your energy supplier can’t fix problems with the network. The sooner we know about problems, the quicker we can respond. To find out more about how you can prepare for a loss of power, click here.
