CU Tripping out

[TJ1]

My sister had a new boiler fitted a few weeks ago and since then the CU trips out on the boiler circuit 2 or 3 times week, any ideas as to why please?
A new CU was fitted at the same time.

Get the fitters back in! Do they have paperwork for the CU or boiler, were they notified/self certified?

Yes she is doing but wondered what reasons would be. She is on her own and doesn't want someone telling her anything.

Is this an exclusive circuit for the boiler (ie nothing else on there?)

What is the device that is "tripping out". and RCD, MCB, RCBO?? They each have their own reasons for de-energising the supply.

Here's how to tell
