How can I test my unit?
You can see if your current unit has an RCD by looking for a TEST button. If it has one try it out and see if it’s working, and if not get in touch with us and let us know as soon as possible.
When we upgrade your consumer unit you will be issued with an installation certificate and a Part P certificate, so call us on 01493 717 206 to ask for advice on consumer unit upgrades and get a free quote.
