If I get a competent electrician over to fix it, how much should I expect to pay?

This is how the wires are now after changing the blue one. Is it correct?

Blown a fuse on the spur switch box? I changed that before but will give it another try with a known working fuse. The MCB is not tripped this time. The switch is up. However, it definitely got tripped when the builder swapped the programmers over the first time.

Didn’t work. I switched the blue cable from where it was to neutral. Nothing. The spur switch did not turn on. The red light did not come on. Tested with voltage pen as well . No electricity to the programmer, relay box, etc.

I will turn off the electric supply to the entire house (for safety) and then put the blue in neutral and see what happens. I am not too familiar with electrics though have done little jobs in the house now and then. Not a complete novice. I mean I can switch the blue wire to neutral myself...

I had the two programmers switched by a builder (he also works with electrics when he needs to). I am sure he didn’t touch or switch any of the wiring around. I was away for a while when he was replacing them. I can’t be 100% sure simply because I wasn’t there when he did it and I hadn’t taken a...

I have one of those electricity testing pens but not a multimeter

Here is a clear pic of the wiring

All the switches on the circuit breaker are on

Here are the pics of the old and the new. The first programmer is the old one, the other is the new (well new in the sense it was bought in the last few days but not brand new).Third pic is wiring as it is with existing programmer. The wiring hasn't been touched. Reason for replacement is the...

It was a like-for-like replacement (with a new ST400C) where the old one was taken off the back plate and the new one slotted in (without touching any of the wiring), but just as the new one slotted into place, the fuse indicator light on spur went off and the boiler switch in the fuse box...
