There are three parties that may be involved in upgrading a main fuse
We don’t own all of the electrical equipment at your property, so you may need to contact your electricity supplier (the company you pay your electricity bills to) and a qualified electrician to complete some work before we can safely upgrade your fuse.
The equipment we are responsible for
We own the power cable which delivers your power and the main electrical fuse which controls the amount of power coming into your property. This is the fuse that we can upgrade for you. We are also responsible for the cut-out box which protects and holds your fuse. We are not allowed to work on any other electrical equipment including your electricity meter and fuse board.
Electricity supplier (the company you pay your electricity bills to)
Your electricity supplier is responsible for your electricity meter and the meter wires, sometimes known as tails, which run from our fuse to your meter. They will be able to check if your meter wires, or the meter itself, needs to be changed to cope with a main fuse upgrade.
Electrician or Installation company
The fuse board and the wires which run from it to the meter, are the responsibility of the property owner. These wires can also be called consumer tails or consumer cables. To check if they need upgrading, you should contact a qualified electrician, or your installation company if you are installing new equipment such as an electric vehicle charger.
Some properties have an additional switch known as an isolation switch, which is the joint responsibility of the property owner and the electricity supplier. Not all properties have them.
For more information on the electrical equipment mentioned above, including the isolation switch, watch our short video.
