How do the SO districts compare?

A district is the first half of a postcode. Each row gives its typical home price, how many of its postcodes can get gigabit broadband for every home, and how many have a home at flood risk. Each opens the district.

Prices: HM Land Registry, files dated 28 September 2026; the bar is set against the dearest district. Gigabit: Ofcom, Connected Nations, Spring 2026, counting postcodes. Flood: Environment Agency, published 6 July 2026, postcodes in England with a home or business in an area at risk from rivers or the sea. How we use them

One row for every district in the area. "No place listed" means no town or village is large enough to list for it.
