Installations or appliances should all be tested regularly to prove they are electrically safe and fit for purpose. We can advise on what should be tested and when it should be tested. All electrical work should be tested to ensure you get the correct certificate by employing RJA Electrical.
Portable Appliance Testing is the testing of basically anything with a plug on it.
This test is for the regular inspection and testing of the fixed wiring within a property. Anything supplied from the fuse board gets tested.
This test is reserved for new installations or any new circuits which are installed into an existing installation.
This certificate is for when you get an additional light or socket installed, for example. If any circuit is modified, it should be tested to ensure it is still compliant and safe.
As approved contractors of the NICEIC you can rely on RJA electrical to provide the correct certification.
