Mrs RR switched on bedroom (in loft) lights this morning and a bulb popped. It has taken out the circuit for the loft lighting and also the first floor bathroom (I assume they are on the same loop as done at the same time 5 years ago). Immediate thought was fuse has tripped but all fuse switches are up (and I have reset for good measure). No joy. I have also replaced the faulty bulb and tried a new wall switch in case something happened there, still no joy.
I'm waiting for the guy who did the original work to come back to me. In the meantime is there anything obvious I have missed to check before the darkness descends?
Swap the breakers in the consumer unit around to see if its a faulty breaker?
Are the lights low voltage types or are they powered directly by the mains?
Are the bedroom/bathroom/loft lights fed from another circuit via fused spur?
Another consumer unit somewhere?

Direct from the mains I believe.

Not sure, this could be possible, I'm guessing this would be sitting somewhere off the breaker board rather than under a floor (gulp!)
Another consumer unit somewhere?
Nope

Just had the the cover off the consumer unit, I'm not going to start to mess with that right now as looks like starting to move wiring around which I don;t have much time (or qualifications) for.
The breakers should just plug in and out
Update:
In taking the advice above I started to look for a fuse spur and found what I had previously thought not there, a second small consumer unit put in at the time of the loft conversion (and partially hidden by the new electricity meter which has been placed in a stupid positon)!!
Breaker flipped and back in business, thanks all (and apologies to duncancallum for my denial!).
The fused spur maybe fed from the loft bedroom socket circuit?
Edit
Glad you got it sorted!
Same mcb (breaker) for first floor bathroom and loft (2nd floor effectively I assume)? Or was it the main breaker in that box that went?
They should be on distinct feeds if they're on different floors and I'd expect the mcb to trip not the main breaker.
Yes, the 'new' mcb / breaker that was installed with the loft / bathroom rather than on the main breaker box (where I was looking at first).
Sorry, I mean...
Your new unit, which is hidden behind the meter, will have a main breaker (taking everything on that consumer unit on and offline) and then multiple distinct mcbs doing things like lights, sockets, bathroom extractor etc.
Is it the same mcb for the lights across the first and loft (which I assume is not the first floor but above it somewhere), or did the main breaker in that consumer unit trip, taking sockets etc with it?

not on equipment from this century

No, just the breaker for the light circuit, not the whole thing so sockets etc were all working.

You just need a bigger unplugger...
No, just the breaker for the light circuit,
Hmmm, not sure how "acceptable" that is, certainly I was always taught circuits shouldn't span floors, that said I've never checked if that's regs or received wisdom.

odd both my 17th edition plastic boxes and my 18th edition metal clad box all require screw drivers to remove the cables.
