Start by noting exactly what has lost power and what still works. This helps separate a network power cut,
a whole-home problem, one affected circuit or area, and one failed point. Repeated tripping has its own
RCD and RCBO guide.
Safe checks with covers left on
Check whether neighbours or nearby street lights have also lost power. Use Powercut 105 to check or
report a network outage.
If only your home is affected, look at the normal switch positions on the consumer unit only when it
is dry, closed and undamaged. Never remove its cover.
For one failed light, note whether nearby lights work. Where safely accessible, switch the light off,
let the lamp cool and try the correct lamp. For two-way switching, isolate that lighting circuit
first.
If several appliances share one extension, switch them off and reduce the load. Never join extensions
together, and fully unwind a cable reel when using its full rating.
When to move to fault finding
Book diagnosis when the loss stays inside the home, the correct new lamp does not solve one failed
light, or several linked points are affected.
Stop using a lead that is hot, damaged, discoloured or smells of burning.
For tripping protection, use the RCD or RCBO guide. For heat, smoke, sparking or a burning smell, use
call-first guidance.
