Split the cost

Per person, a shared car beats the typical bus fare once 4 people share it (✓).

Per-person figures use the middle of each estimate. The low end of the car range assumes your own car (fuel and tolls); the high end adds a one-day hire car.

Flight: not practical here - Too short - airport time would outweigh the flight.

How we estimate

Bus uses the duration, distance and typical fare range in our route data (editorial figures, not live quotes).
Train, flight and drive are estimated from the 185 km road distance (with fixed average speeds and per-kilometre price bands, scaled to this route’s own bus fare level). A straight-line distance of about 80% of the road distance is used for flights.
Door to door adds the time that is not travelling: about 55 min for a coach (to the station, boarding, onward), 50 min for a train, 195 min for a flight (to the airport, check-in and security, baggage, into town) and 25 min for a car (loading, parking).
Cost is a cheap-to-flexible range per person; flights include airport transfers; cars are priced per car (fuel and tolls at the low end, plus a one-day hire car at the high end) and split between up to four people.
CO₂e per traveller uses typical factors per passenger-km: coach 0.03 kg, train 0.04 kg (0.015 kg on electric high-speed lines), short-haul flight 0.14-0.23 kg without radiative forcing, car 0.17 kg per vehicle-km shared between the people in it.
Scores run 0-100: time (fastest door to door = 100), cost (cheapest typical total = 100), comfort (our editorial rating, lower for very long rides) and green (lower emissions per km = higher). Best overall weights them time 35%, cost 30%, comfort 20%, CO₂ 15%.
Not every corridor has a direct train or airport service, and car journeys may involve ferries or tolls we do not know about. Treat everything except the bus figures as a starting point and check the operators.

The cheapest way from London to Bath is the bus (about £8–22 per person); the quickest is the train (about 2h 55m door to door); the best overall balance is the train; the lowest-carbon choice is the bus (about 5.6 kg CO2e per traveller). The bus takes about 3h 15m on the road over roughly 185 km. Bus figures come from our route data; train, flight and drive figures are our own estimates, not live prices.

Fares and times other than the bus figures are estimates for planning only - they are not offers or live prices. We don’t sell tickets; compare live prices with the providers further down this page.
