the way we saw it. When looking for our new place, we looked on Rightmove, Zoopla and less so, Prime Location.
if it was not on there, we would not bother. YOPA and such internet companies market your houses on those sites (as well as the high street agents)
also, you have your own online dashboard to manage your listing and viewings. Your Agent will message you on there or by text and people who want yo view your place can ask you questions via the dashboard
we had to be home for any viewings, so it made sense to go with an online company
One high street agent wanted £2750 to sell our place (that was a special offer, reduced fee). YOPA wanted £780 and that was payable within 6 months
Walking down our version of London Rd for example and registering with high street agents just never crossed our minds.
