Who Is the DNO and What Do They Do?
If you’ve ever reported a power cut or searched online for “Who is my DNO?”, you’re not alone. Many people know the name of their energy supplier, but very few know about the company that actually delivers electricity to their home.
A Distribution Network Operator, usually called a DNO, is the company responsible for the electricity network in your local area. They own and maintain the underground cables, overhead power lines, substations, and other equipment that carries electricity from the National Grid to homes and businesses.
Although your energy supplier sends your bill and manages your account, they do not own the local electricity network. That’s why your supplier cannot repair damaged power lines or restore electricity after a network fault. Those jobs are the responsibility of your local DNO.
When Should You Contact Your DNO?
Your DNO is usually the right company to contact if:
There is a power cut affecting your area.
You notice damaged or fallen overhead electricity cables.
There is damage to electricity equipment outside your property.
You need to report a safety issue involving the local electricity network.
If you’re not sure whether the problem is affecting other homes, a quick search for “power cuts in my area” can often show whether a fault has already been reported. You can also check if your neighbours have lost power. If several properties are affected, your local DNO is likely to be investigating the problem.
When Should You Contact Your Energy Supplier Instead?
Your energy supplier should usually be your first point of contact if your question is about:
Your energy bill.
Meter readings.
Your electricity or gas meter.
Changing tariffs.
Moving home.
Payment or account enquiries.
If your home has lost power but there are no reported power cuts in your area and your neighbours still have electricity, your supplier may need to investigate first. In some cases, the problem may be related to your electricity meter or another issue they are responsible for. If the fault is found to be on the local electricity network, they will normally direct you to your DNO.
Why Is It Helpful to Know Your DNO?
Knowing the difference between your energy supplier and your Distribution Network Operator can save valuable time when something goes wrong. Rather than contacting the wrong company and being redirected, you’ll have a better idea of who is responsible for fixing the problem.
Understanding how the UK’s electricity network works makes dealing with power cuts and electrical faults much less confusing. Your supplier looks after your account, while your DNO looks after the network that keeps electricity flowing safely to your home.
