London is not one football market but half a dozen overlapping ones. Arsenal and Tottenham contest the north London derby, Chelsea and Fulham sit in the west, West Ham in the east and Crystal Palace in the south, and that is before the clubs outside the top flight. The practical consequence for a household here is that your local game is almost never the one being shown, because broadcast picks follow the national audience rather than the postcode. London also has the heaviest concentration of Irish, Caribbean, South Asian and eastern European households in the country, which means demand for channels that no domestic package carries at all. That combination, too many local clubs and too many home countries, is why so many London homes end up stacking subscriptions.
London's practical problem is housing rather than infrastructure. Enormous parts of the city are flats, conversions and purpose-built blocks where a dish is not permitted, and in the conservation areas across Camden, Islington, Kensington and much of the centre it is effectively impossible. Add the highest private-rental share in the country, with tenancies frequently under two years, and a long contract tied to an installation becomes a genuine liability rather than an inconvenience. Coverage itself is generally strong from Croydon to Barnet, though older blocks lag. The test worth running in London is a weekday evening in your own flat, on your own connection, because building-level infrastructure varies far more here than street-level maps suggest.
