Which UK Outcodes Have the Fastest Broadband in 2026?

Ofcom Connected Nations data, ranked by outcode. FTTP coverage, average download speeds and the "slow but pays a lot" outcodes that buyers should know about.


Why broadband matters for property value


Buyers used to ignore connectivity. Post-2020 it became a top-3 search filter on Rightmove. A 2-bed flat with FTTP gigabit goes for measurably more per square metre than the identical flat in the same building with copper-only ADSL.


We score broadband as a full input on every property report — speed tier, technology mix, % FTTP coverage from Ofcom Connected Nations data.


The fastest UK outcodes (May 2026)


Outcodes in the top 1% nationally for broadband: most central London (E1, EC1–EC4, WC1, WC2, SW1), most central Manchester (M1, M2, M3, M4), large parts of Glasgow (G1, G2, G3) and Birmingham core (B1, B2, B3, B4). All ~98–100% FTTP coverage.


The 'pay London prices for slow internet' outcodes


The painful ones: large parts of Westminster (W1, W2 cores), conservation Hampstead (NW3), some of Marylebone (W1U). High asking prices; FTTP rollout incomplete because of conservation-area cabling restrictions.


Always pull the Ofcom postcode-checker before offering on a £1m+ home if you work from home.


Rural is more nuanced


Stereotype says rural = slow. Reality: many recent rural USO programmes have brought 100–300 Mbps fixed wireless to villages that previously had 8 Mbps copper. Our broadband data shows surprising bright spots in Cumbria, parts of Cornwall, the Highlands, and most of the Welsh national parks.
