NPPF (2026) · Well-connected stations
Is Portsmouth & Southsea a well-connected station under the new NPPF?
The short answer
Yes. On the weekday timetable Portsmouth & Southsea averages about 17.2 trains an hour, with about 9 an hour in its busiest direction, passing the frequency test, and it sits in the Portsmouth travel to work area, ranked 26 of the top 80 in England by economic output. Within about 800 metres, residential schemes must achieve at least 45 homes per hectare of net developable area. The service is at least twice the well-connected minimum, so the higher floor of 45 homes per hectare applies.
