what’s happening? No power to the boiler or it’s just not turning in?

Did you have a external timer already installed as it’s sounds like you’ve connected something to mains that’s shouldn’t be eg 240v

Have you checked your 3 Amp fuse for the heating supply.

@ShaunCorbs Sounds like he's just swapped the clock for like for like to me

you tried pressing the power button on the boiler ?

Have you altered any wiring or just clicked one clock off and fitted another

Depending on the age of the boiler it might be under warranty or you could get a local pro in

Either the clocks blown something in the boiler when it's gone, or you've had a power surge that's taken the clock and the boiler out at the same time.

Time to get someone in i'm afraid.

Are you able to confirm any voltage presence at the fused connection? Eg to the fcu and load to boiler?

Ok, then as per the others, might be time to get someone in, could be a loose wire, or a blown fuse inside the boiler.
