Not very, unless the question means broadband. Almost nobody here gets to work by train or bus. More than half of households keep two cars or more. Gigabit internet reaches nearly every premises. Connected is the wrong word for this place: it solved the problem indoors and left the roads exactly as they were.
There is no railway station in the village, and the share of people commuting by train is under 1%. Buses exist in a technical sense. There are 14 stops inside the village's mapped area, and under 1% of residents use one to reach work.
What people actually do is drive. About 58% commute by car, and about 34% work from home, which is the second largest answer by a wide margin and the reason the rest of this is survivable. About 4% walk and under 1% cycle. Around 10% of households run no car at all, while about 55% keep two or more. Out here the second car is not an indulgence, it is infrastructure with a tax disc.
The Department for Transport's modelling puts the nearest town centre at about 17 minutes by car and about 29 minutes by public transport, which is the entire connectivity argument compressed into two numbers.
Broadband is where the village quietly outperforms places with railway stations. Gigabit service reaches about 94% of premises, superfast reaches all of them, and none fall below the universal service obligation. Mobile coverage from at least one operator reaches about 100% of the area, with all operators together at about 91%.
The same trip to a town centre comes out at about 32 minutes by bicycle and about 88 minutes on foot. Those are modelled national statistics for the area rather than a route measured from any particular front door, and the walking time is the finding rather than a piece of trivia. Nothing that qualifies as a town is within walking distance of here.
For everyday destinations the same journey-time statistics are kinder. A doctor's surgery sits about 6 minutes away by car, 8 minutes on foot and 8 by public transport, and a food store about 6 minutes by car and 8 on foot. A hospital runs about 24 minutes by car and about 68 minutes by public transport. Employment centres come out at about 23 minutes by public transport against about 73 minutes by car, which says considerably more about the model than about any road anyone has driven. The public transport figures date from 2019 and services have thinned since, so they deserve more suspicion than the car and walking times, which age far better.
Current service data is blunter than a stop count suggests. Those 14 stops average about 14 scheduled weekday departures each, all of them carry some weekend service, and in the peak hour the average is under one bus per stop. Fourteen departures spread across a whole day is a service that sets your schedule rather than one that fits around it.
Road noise is a non-event. No postcodes sit near or above the 65-decibel threshold that official noise mapping treats as significant road noise, and none reach it for railway noise either. Whatever the trade-off is for living here, listening to traffic through the bedroom window is not part of it.
Connectivity is where Yealmpton comes off worst of anything on this page. The fibre is excellent and the timetable is decorative, so the honest summary is a village wired for the century it is in and roaded for the one before.
