Cannot recommend this company enough, broke/melted my glasses on Wednesday, picked up a new pair of frames from Vision Express that night (they said 2 weeks for glazing!)
So I sent them away to Specs-By-Post Thursday and have just received them back this morning (Saturday).
They are also significantly cheaper glazing options then high street.
Defo consider them if you need a reglaze or even if you buy new frames elsewhere but need prescription. They do also sell frames i think.

Linsey and the team there are amazing!
