RCD's do fail but not very often. More likely you have a fault and likely that will be on the neutral so switch off the MCB will not help.

Unplug everything and switch off any fused connection units (FCU) and see if it's easier to reset and then plug in one thing at a time only when required and see if you can work out what it is that's causing the trip.

Look at areas where electricity may be exposed to water or damp.
Especially outdoor power outlets and lights.

Look also at heating pumps and valves. They can leak and cause problems.
