Antique bracket Clock service - Suggestions?

Perhaps a bit of a stretch for a watch forum but I have an antique bracket clock of some quality that needs to be serviced and wondered if anyone here had any suggestions as to who might be able to do this. It has a moon phase and date complication which have not worked for some time, along with being stuck at six chimes for any hour of the day, so would dearly like to get this sorted. I live in London and in the past used the clock clinic, but would really like to foster a new relationship with a "craftsman" as have several other clocks that will need servicing in due course.

thanks for any help and advise.

Not in London but I use a chap locally in Swindon. He's had all sorts from a friend and I, longcase, simple barograph, loads of 8 day mechanisms, 400 day and even my congreve and an incline clock.
Very approachable and reasonably priced. Not terribly swift but I doubt any of them are!

I can recommend John Jillings who used to be based in Newent, Gloucestershire (where I used to live) but I note has now moved to Powys, Wales.

I can recommend Gutlin Clocks on Kings Road

Thanks everyone for the various suggestions, will look into them and hopefully work out a good way forward.
