What's an isolation switch?
An isolation switch is a piece of equipment which can be installed on a metering supply that will allow the supply to be de-energised after your meter. It normally sits inside your meter box and it sits after the meter but before the consumer unit.
What does it do?
An isolation switch acts as a circuit breaker on your mains electrical supply, so that any electrical work (such as an EV charger or solar installation) that is going to take place within a property can be completed safely by a private electrician or anyone doing electrical work on your home. When the switch is turned off, there would be no power after the isolation switch, which in turn would allow a private electrician to complete any maintenance work or repairs on the member's internal electrical set up.
What does an isolation switch look like?
The isolation switch is circled in yellow on this photo. It's normally located inside your meter box.
Who's responsible for installing an isolation switch?
An isolation switch needs to be installed by your supplier. This is because the supply would need to be de-energised via the cut out and private electricians are not permitted to work on the cut out. Therefore, the supplier would need to arrange for an engineer to go to the property to install one.
How can I arrange an isolation switch install?
Reach out to your energy supplier, it’ll need to be scheduled as a non-essential maintenance job. There is normally a charge for this, and it's typically in the order of around £150 but this varies by supplier.
