Hi

can anyone recommend a climbing coach to give pointers and feedback on technique on (indoor) lead? Based in the London area. 
thanks

Jamie might be worth a try, depending on where in London you are:

I'd definitely recommend getting in touch with Xian: https://www.xiangoh.com/

Incredibly knowledgeable on climbing technique, and is a really engaging, fun and inspiring coach! 

Stronghold have in-house coaches. Jon Nino is particularly knowledgeable and friendly. Also, it’s easy to switch coach if who you have doesn’t work for you.

Olly from Livedreamadventure also does days in London - I recommend him hugely.

Yes indeed, no slight on Olly intended, just thinking Jamie's more available for the London-based

Oh absolutely, no slight taken whatsoever!

Both absolutely superb I’m sure, said it more to backup your reccomendation, and to give the OP another option in case Jamie’s not available on his dates.
