Network Railcard for South East England

For only a small annual fee, you can save 1/3 on most fares in South East England, including routes in and out of London, with the Network Railcard. Covering both standard and off-peak tickets, this railcard is particularly beneficial for those who travel regularly within this region.

Split Tickets to save an average extra 30%

Splitting your tickets involves purchasing separate tickets for different segments of your journey instead of a single ticket for the entire trip. This method is legal and can often result in cheaper fares. For example, if you are travelling from A to B, you might discover that buying a ticket from A to C, and then another ticket from C to B, is more economical than purchasing a direct ticket.

Traveling during off-peak hours

Taking advantage of Off-Peak train tickets is another effective way to save money on your train journey from London to Heathrow Terminal 5. These tickets are generally cheaper than peak-time tickets and can be used during less busy periods, typically outside of the morning and evening rush hours. If your schedule allows for flexibility, opting for off-peak hours can lead to substantial cost savings. It's important to note that in most cities and large towns, off-peak hours usually start at 09:30 from Monday to Friday, while in other areas, they typically begin at 09:00.
