I just fitted a new light to my dining room ceiling but wired it up wrongly
which caused it to blow. I trimmed the ends of the wires and re-wired it back
up correctly but now my light fitting isnt working. Have a permanently
damaged something?

More likely it's not wired correctly.

Yes your credibility in the family.

Yes indeed and have we all not done that many times before?
However I think I'd want to make sure the fitting and its bulb worked as
well in case its a duff one.

The problem with ceiling roses for the uninitiated is that they can, at
least in UK, contain lives that are not switched as well as one that is. If
you have more than one switch the thing tends to get quite mind numbing.
Of course, It also might not do the writers cred any good posting from that
Home owners hub dodgy web based newsgroup site either.

Upload some photos somewhere, then post a link to them here ...

A year or two back, my neighbours were having a kitchen re-vamp as part
of an extension. Having removed the ceiling rose along with the
ceiling, while waiting for the sparky to arrive the next day, the
builder kludged the wires into a choc-block (all reds together, all
blacks together, don't bother with the earths).

The neighbour walked into the kitchen, knowing there was no light but
old habits die hard, so clicked the light switch anyway ... BANG!!

Sounds like you still have a wiring problem. Lights and ceiling rose
connections are often somewhat non intuitive since you frequently have a
wire of the wrong colour in there to confuse things!

If you look at:

http://wiki.diyfaq.org.uk/index.php/...Loop-in_Wiring

You will see the difficulty comes with the wire that goes to the switch.
That needs to take a live feed to the switch, and then bring it back
again. That means that both the wires are used as live conductors, but
one of them is (usually) coloured as a neutral. There should be some
over sleeving or tape on the re-proposed neutral, but that is often
missing.

If you give us a bit more detail on what wires you have, and perhaps a
photo, we can give you a step by step process to fix it.

Have a permanently damaged something?

Unlikely.

I welded a screwdriver blade to the screw once due to a whisker of the wire
touching it from the adjacent connection.

Oh dear, well we used to have old fashioned fuses as well, and remembering
which wire was for which circuit was a little hard and of course we were all
in the dark and torches in those days batteries tended to last about five
minutes.

Yes at least in our house the wires have the old red and black which in fact
means a light probe can be used by a blind person. The brown and blue
reflect light equally and hence cannot be seen as different by the device
which is just light and less light so to speak. However, nowadays I think
the climbing on steps and fiddling with mains wires days are long over for
me. I get a bit dizzy before you start worrying about the lack of eyesight!

For those of you who remember rise and fall lights over the dining
table, after I fitted one in my Victorian house (nice high ceilings!) a
friend and neighbour of mine decided to do the same.

That was exactly how my mate wired it.

But he wasn't a brickie, he was a GP who before turning to that calling
had done medical research in Cambridge and at Harvard, who had a better
golf handicap than most club pro's, and sang opera at professional level
(he almost went into that instead of medicine).

Guess who fixed it.

Probably a lightswitch!

Surely a light switch in this instance is likely to fail short with
welded contacts if the switched live was connected to neutral?

Yup, fair point. Wiring should be ok, but the switch could well be shagged.

It will fail in whatever way it wants to:-)

I would say 50/50 in which way on my experience.
