Understanding a London postcode
A London postcode is not a borough label, even though people use them that way in conversation. SW1 and E14 can sit near very different street characters. Treat the full code as the unit of truth when you compare sold prices or commute times.
Central districts such as EC and WC lean commercial; residential demand spreads across N, E, SE, SW and outer zones. Pair the outward code with a map pin before you assume lifestyle fit.
