In short: Rightmove is the UK's largest property portal by traffic, Zoopla offers listings plus valuation estimates and sold price data, and OnTheMarket sometimes carries homes before the others. Coverage overlaps but isn't identical, so set alerts on more than one. Sellers can't list directly; agents upload homes to the portals. Some homes are sold off-market before they ever appear, so registering with local agents also helps.
