Transport connectivity in London is measured by TfL using the Public Transport Accessibility Level (PTAL) — a scale from 1a (very poor) to 6b (excellent) based on the number, frequency, and proximity of public transport services at any given location. LondonIQ converts this to a 0–100 score for easier comparison. Higher PTAL scores reflect denser tube, rail, and bus networks — meaning more route options, higher service frequency, and shorter waits. As a rule, inner London boroughs score highest simply by virtue of their centrality, with tube lines converging and bus networks overlapping extensively. But several outer London boroughs — particularly those served by the Elizabeth line, DLR, or multiple Overground routes — can challenge and even exceed some inner boroughs in specific areas. Transport score is a borough-wide average: the range within a borough can be wide, so always check at postcode level.

Frequently asked questions
Which London borough has the best transport links?
Inner London boroughs dominate the top of the transport rankings — Westminster, Camden, Islington, and the City of London all have extremely high Public Transport Accessibility Levels (PTAL) due to their density of tube, bus, and rail connections. Among boroughs where you are actually likely to live (rather than just work), Southwark, Tower Hamlets, and Hackney offer the best transport accessibility combined with residential neighbourhoods.
What is the best area to live in London for commuting?
For commuting to the City or Canary Wharf, Tower Hamlets offers the fastest and most frequent connections — many areas are just 5–15 minutes by DLR or Elizabeth line. For commuting to West End or Midtown jobs, Southwark and Lambeth offer multiple tube and rail options with sub-20-minute journey times. For value and commutability combined, outer boroughs like Greenwich (Elizabeth line) and Waltham Forest (Victoria line) offer compelling alternatives.
Where in London has the fastest commute to the City?
The fastest commutes to the City of London come from Tower Hamlets (5–10 minutes by DLR or tube from Bethnal Green, Whitechapel, or Poplar), Southwark (Borough, London Bridge — under 10 minutes), and Hackney (Old Street — 5 minutes). Newham also benefits significantly from Elizabeth line access to Liverpool Street in under 10 minutes from Stratford.
