Saving Money

Cheapest Bus

The cheapest bus ticket from Cardiff to London is a regular seat, one-way trip, when booked in advance. Buying on the day of travel is usually more expensive and may include additional costs that can vary depending on the time of day and bus class.

Cheapest Bus
Book in advance.
Most companies sell bus tickets about three to six months in advance. If you already have your travel date set, search as early as possible to save money.
Be flexible with your travel times.
Many companies increase ticket prices during "peak hours" (usually between 06:00 - 10:00 and 15:00 - 19:00 on weekdays). If possible, choose to travel outside of these hours to find cheaper tickets and save money.
Check connections.
On some of the busiest routes, you may also have the option of taking a slower or connecting transportation. It may take a little longer, but if you have a bit more time available, you may find a cheaper ticket.
