Summer sales in London begin in the last week of June. The last major sale to open is Harrods, which begins on the first Wednesday of July (3rd this year). Every shop/store starts at a different date, so you might want to contact beforehand the ones you are interested in. Shoe lovers who are in London (at any time of the year) can also travel to Northampton (world capital of shoe manufacture). Almost all the big firms like Lobb, Crockett, Trickers, Church (but not Edward Green) have factory outlet shops on their premises, where they sell seconds or oddments at greatly reduced prices. Some of these shops operate daily, others only one or two days a week. Contact beforehand. PS. Winter sales begin right after Christmas.
