Electrical faults should never be guessed at. We test circuits properly to find why a breaker trips or a light won't work, then repair it safely.
An MCB trips when a circuit is overloaded or short-circuited. An RCD trips when it detects current leaking to earth, often from a faulty appliance, water getting into an outside light or socket, or damaged cable. We isolate circuits and appliances one by one and use an insulation resistance tester to find the fault.
Small jobs welcome.
Switch off at the consumer unit and call for help if you notice any of these.
Knowing the parts of your fuse box helps you describe the problem quickly.
Switch all MCBs off, reset the RCD, then turn circuits back on one at a time. If one circuit trips it, unplug everything on it and plug items back in one by one. If it still trips with nothing plugged in, the fault is in the wiring and needs testing.

Repair and re-test
Often a faulty appliance or a wiring fault. We'll test the circuit to find the cause.
If it trips again straight away, stop. There is a fault on that circuit and it needs testing.
A loose bulb or connection, an incompatible dimmer with LED bulbs, or a loose connection in the circuit. Flickering with a burning smell needs urgent attention.
Yes, we can add new sockets or USB sockets by extending an existing circuit where it's safe to do so.
It's safest to use someone competent. Always isolate the circuit at the consumer unit first, not just the wall switch.
