Portsmouth is well connected in almost every way except the one buyers ask about first. Barely two in a hundred commute by train. Close to three in ten households run no car at all. A quarter of workers do not leave the house. The network here matters less than the fact that almost nothing in this city is far from anything else.
There are stations across the island and its mainland edge, at Fratton, Hilsea, Portsmouth and Southsea, Portsmouth Harbour and Cosham, with more up the line at Bedhampton, Havant, Portchester and Fareham, plus the hoverport at Southsea. Direct trains run to London. Despite all of that, only about 2% of residents commute by rail and about 5% by bus, across 742 bus stops in the area. Those numbers are not an indictment of the railway. They are what happens when the commute is four miles long and the train is a solution to a problem most people here do not have.
The commute mix tells the real story. Around 43% drive, about 25% work from home, roughly 12% walk and 5% cycle. Car-free households run at about 29%, while about 28% keep two or more, which is a city split neatly between people who gave up on parking and people who doubled down on it.
The Department for Transport's modelled journey-time statistics put the nearest town centre at about 9 minutes by car, 15 by public transport, 12 by bicycle and 20 on foot. Those are modelled for the area as a whole rather than measured from any particular front door, and the bicycle beating the bus is not a rounding error. It is the shape of a dense island city with short distances and a lot of traffic lights.
The same statistics put a doctor's surgery about 7 minutes away by car, 11 by public transport and 12 on foot. A food store is about 5 minutes' walk or 6 by car. Employment sits around 8 minutes by car and 11 by public transport. The hospital is the outlier and worth knowing before you need it: about 16 minutes by car, 33 by public transport, and about 68 minutes on foot, which is less a walking time than a warning. One caveat on all of these: the underlying journey times date from 2019, so the distances hold up but the public transport numbers should be treated as the optimistic version.
Bus stops are easy to count and mean nothing on their own, so here is the part that matters. Across the 652 stops carrying service data, there are around 585 scheduled departures per stop on a weekday and about 34 at peak hour, and roughly 99% of stops keep some weekend service. A city where Sunday still gets a bus is doing something most of the country has quietly stopped bothering with.
Broadband is close to universal. Gigabit reaches about 93% of premises, superfast about 98%, and nothing at all sits below the minimum broadband standard. Mobile coverage from at least one operator reaches every premise, and so does coverage from all operators, which removes the usual conversation about which network works in the back bedroom.
The noise mapping is the least flattering item here. Around 100% of postcodes sit near or above 65 decibels of road noise, the level at which official mapping treats it as significant, with the loudest mapped band reaching 75 decibels. Rail noise is separate and much narrower, touching around 26% of postcodes with a top band of 70 decibels. Dense city, short journeys, permanent hum. The three facts are the same fact.
For electric vehicles there are 136 public charge points in the area offering 179 connections, of which 9 are rapid. That handful of rapid units is the difference between charging as an errand and charging as an appointment, and with most of the housing lacking a driveway, it is the number to check against where you would actually park.
Connectivity is one of Portsmouth's genuine strengths, though not in the way the station list suggests. The rail service is ordinary and the road noise is constant. Everything else is close enough that neither ends up mattering much.
