Fulham or Chiswick: the short answer
Schools and green space
SW6 has 6 registered secondary sites and 11 public parks. W4 has 1 secondary site and 126.47 hectares of mapped green space against 83.58 hectares.
SW6 has the broader school and public-park list. W4 has the larger mapped green-space area.
Local area profile
W4 has the more affluent local-area profile overall: 6/10 versus 5/10 in SW6. On this Government scale, 1 is the poorer end and 10 the more well-off end.
W4 has more neighbourhoods at the better-off end of the scale. SW6 has more at the poorer end.
Connectivity
Broadband is identical at a 1,000 Mbit/s median. SW6 has 108 bus nodes and W4 has 94. Rail, metro or tram nodes are 19 and 20.
Broadband will not break the tie. The actual commute is the deciding test.
There is no broad price winner here. A buyer comparing similar homes is choosing between two areas in the same price conversation, so the property itself should carry more weight than the postcode badge.
Start with SW6 if a broader registered school list and more public parks matter most to your routine. Start with W4 if you place more weight on a slightly more affluent local-area profile and a larger mapped green-space area. Broadband does not separate them. The remaining decision sits in the particular street and building you prefer.
Price and the building
W4's median recorded sale is £12,750 higher than SW6's, a 1.7% difference: £765,000 against £752,250. This leaves the building itself, its tenure and its costs as the main value questions.
