Alya, this could limit our usefulness in identifying your roses, unfortunately. Most of the rose forum members live in the United States or Canada, and the roses that are popular here aren't necessarily popular in England. I know, for instance, that Sweet Dream was the number-one rose in England for many years, but it has always been quite difficult to find here.
It also explains the height of the yellow hybrid tea. Harkness, for instance, has produced a number of hybrid teas that grow to only about 90 cm. They're almost unknown here because the nurseries here carry mainly hybrid teas that are at least a meter in height, and most are between 3 feet and 5 feet tall.
If the rose in the middle group of photos was on the property when you moved in, you can ignore my guess of Rainbow Sorbet. It isn't old enough to have been available in England more than 12 years ago.
It might be worthwhile to look for your mystery roses among the McGredy and Dickson roses. Sometimes gardeners have favorite hybridizers, and the roses you've been able to identify (Arthur Bell and Elina) were hybridized by McGredy and Dickson.
