In reply to GraMc:
I can also recommend George at http://www.shoedoc.eu/rock%20climbing.htm
Turnaround is a bit longer than normal, but I've already had 3 pairs returned since he started back after the Greek lockdown.
Cost out is about £9 for two pairs (I rarely send fewer than 2 at a time) and return is included in the cost.
It's not so much the cost, but the quality of repair I use them for. The only place in the UK I have found as good is Llanberis resoles. However, Tarquin, the owner, tends to go away for extended trips (can't blame him) and it's not always possible to rely on a quick turnaround.
Hope that helps.
