Not well, unless you own a car, in which case it is fine. Half of working residents drive to work. Roughly one in two hundred takes a train. The broadband is better than the bus service and that is not a compliment to the broadband. This is a place built on the assumption that everyone has a vehicle, and almost everyone duly does.
There is no railway station in the village itself. Truro Rail Station is the nearest useful one, with Perranwell Rail Station further out, and the commuting figures show what that costs: about 1% of working residents travel to work by train, which is close to nobody. Buses do more, with 19 stops across the area and about 3% of working residents using them to get to work.
The commute mix tells the real story. About 50% drive, about 24% work from home, about 13% walk, and about 3% cycle. On the household side, about 44% of homes run two or more cars, and about 13% have none at all. That last group is the one to think about carefully, because a car-free household here is relying on a bus network that exists rather than one that is convenient.
The Department for Transport's modelled journey-time statistics put the nearest town centre at about 15 minutes by car and about 25 minutes by public transport. These are modelled for the area as a whole rather than measured from any particular front door, so treat them as the shape of the journey rather than a timetable.
Broadband is the compensation and it is a decent one. Gigabit-capable service reaches about 61% of premises, ultrafast the same, and superfast about 92%. For anyone in the quarter of the workforce working from home, that is the difference between this being a workable address and an impossible one.
Mobile coverage is close to universal from at least one operator, and about 95% of the area gets fourth or fifth generation service from all of them, which means the network you already pay for probably works here.
On the same modelled basis, the nearest town centre is about 26 minutes by bicycle and about 68 minutes on foot. An hour and a bit walking is the honest finding: this is not somewhere you stroll into town on a whim, and anyone imagining otherwise should look at that number twice.
For everyday things, the same statistics put a family doctor at about 10 minutes by car, about 15 by public transport and about 32 on foot. A hospital is about 12 minutes by car and about 20 by public transport. A food store is about 8 minutes by car and about 18 walking, which is the one genuinely pedestrian-friendly journey in the set. Employment centres come in at about 9 minutes by car and about 11 by public transport. Distances to fixed destinations are stable, but the public transport figures date from 2019 and services have been withdrawn across the county since, so lean on the car and walk times and treat the rest as optimistic.
The current bus picture is better than the commuting share implies. Across the 18 stops with published service data, there is an average of about 132 scheduled departures on a weekday, around 10 in the peak hour, and every one of those stops has some weekend service. Those are departures rather than routes, and a stop with a few buses a day is not a service, but by Cornish village standards this is a functioning network that people have simply chosen not to use.
Road noise is the one thing a viewing will not warn you about. Around 37% of postcodes here sit near or above 65 decibels, the level at which official noise mapping treats road noise as worth recording, and the loudest band present reaches 75 decibels. No part of the area registers on the rail noise mapping. Where your particular house falls in that spread depends entirely on the street, so listen with the window open.
Electric vehicle charging is thin: 2 public charge points in the area, with 3 connectors between them, and none of them rapid. Charging here is something you plan around overnight rather than something you do while picking up shopping.
Connectivity is the weakest thing about Threemilestone by a distance. Good broadband and a workable bus timetable do not make up for no station, an hour on foot to town, and a road network that quietly decides everything about how you live here.
