Where to repair Metz flash?

My trusty Metz 58 AF-2 is now only firing intermittently. Anyone know a good place to have it repaired in London or the UK. Thanks for any assistance. Have already cleaned the contacts, which is the full extent of my mechanical skills!

I am not certain how helpful this will be but this firm does repair flashguns according to their website https://www.fixationuk.com/

Thanks Michael. I'm waiting to hear back from them. Can't recall if they repair or send it out. Any other suggestions in the meanwhile much appreciated.

Just purchased a replacement from the reliable and trustworthy LennyBloke so I'll be posting this one as a freebie shortly, for anyone who can either fix it themselves or live with it not firing some of the time.
