The blue one on the left. It controls the kitchen appliances. Going to call electrician on Monday to check it out.

Do you mean the further-most on the left, or the 'large' blue switch which is fourth from the far left?
If the latter, then turn off the three to its left, then try turning the 'big blue' on. Does it now stay on? If so, try turning the three back on, one at a time. Which one makes it trip?
Close up pic of the group of four?

Electrician charged me £102 inc vat for call out charge.Could not find anything wrong with the consumer unit. A bit dated but not unsafe. Is that the normal rate, I think it was a bit expensive.

There shouldn't be anything wrong with the consumer unit.

There's something wrong elsewhere in the house and the consumer unit is detecting it - this is what we told you before.

I hope you didn't just let the electrician look at the consumer unit and then leave?

Please explain further. Do you still have this tripping issue? Have you tried what I, and others, have suggested?

Please don't tell us the sparky turned up, checked the CU only, didn't examine the actual issue, and departed with your hard-earned in his pocket?

£85 + VAT is extremely fair (and inexpensive) as a call-out charge. It could very fairly be substantially more than this.

The large blue switch. I have not done what you advised as it has happened a few times I wanted to have it checked properly in case there is something wrong with it. 

Paid electrician £102 for call out and his diagnosis was nuisance trip after doing the usual checks.  To call him again if this happens, I do not think I will at this price now that I have been informed nothing serious. Insulation tests  have been carried to all circuits served by RCD which were fine.RCD ramp test was carried out at 27ma, fine according to him. Was it a fair price? Thanks

That's sounds like some thorough testing, so I'd say 'yes', that was a fair price.

So it was the 'large' blue switch that tripped, which is 'good' news. Yes, 'nuisance tripping' is a thing - I was plagued by it for months a couple of years back, and a sparky found now't - but mentioned another house on the same street had the same. Possibly down to voltage fluctuations and spikes and dirt and stuff (I know all the terms...), and it did simply stop happening.

If it does happen again on yours - and fair chance it will at some point - then turn off the three to its left, and try turning the 'big blue' back on. Does it now stay on? If so, try turning the three back on, only one at a time, giving each a good 10 minutes. If you find one that makes it trip, then that will be useful info. But, most likely, one on its own won't - leccy is very annoying that way :-) No harm in trying, tho'.

Thank you very much. Very good advice I will follow if it happens again.

Also, built in appliances have fuser boxes connected (for ease of access) - switch all of these off too
