Think before you dig
If you’re planning any property maintenance or DIY that might bring you close to our equipment, please get in touch so that we can help you work safely. If you’re working in the garden, please be aware of the presence of underground electricity cables. Light gardening shouldn’t present an issue but deeper excavations, for tree roots, fence post replacement, footpath widening, or patio laying might uncover a live cable.
Look Out, Look Up!
Tree cutting or hedge trimming can present a risk of contact with an overhead power line or electricity service wires. Before you start work, check the area affected and keep away from any overhead wires. We can check the cables for safety, measure the height and offer advice and guidance for you or your contractor.
If you're planning your next DIY project or garden renovation and require our help on overhead cables or an underground cable trace, you can request a job on our website with our General Enquiries team. We can check the height of your service wires, temporarily disconnect the electricity supply for safety and, in some cases, apply a protective shrouding to the wires to insulate them while your work is carried out.
Frequently asked questions
All electricity transformers make some noise, usually a very quiet hum, as a result of the alternating current electricity being applied. It’s unusual for this noise to be noticeable under normal situations, but sometimes on a cold clear quiet night, you might be able to hear it when you’re close to the fence or pole.
If you think the humming noise is really loud or unusual please get in touch by sending us a message.
Electric and magnetic fields occur naturally within the body in association with nerve and muscle activity. We also experience the natural magnetic field of the Earth (to which a magnetic compass responds) and natural electric fields in the atmosphere. EMFs are produced whenever electricity is used, in the home, office, or anywhere else. Electric fields are produced by voltage and Magnetic fields by current.
Most of us get some minor exposure from distribution wires, either buried along the street or supported on wood poles, or from the wiring and appliances in our homes.
Electricity substations also produce magnetic fields, but you need to be very close to them and generally inside the perimeter fence, to get an elevated exposure.
It depends on what you are requesting our assistance for, if you are looking to get an overhead line assessment or a copy of where our cables lie these are free of charge. If you need us to disconnect your supply temporarily while you work safely then this may incur a charge.

As a Transmission and Distribution Network Operator, we are generally responsible for the overhead lines, cables and substations providing the electricity service to your home or business. This means that we look after the service cable, either overhead or underground, and the termination or main fuse that’s often found in the electricity meter box or near to your electricity meter.
