Busses 

The £2 cap on single fares is due to run out on 31st March. Until then, check that you're not paying more than £4 for a return, otherwise it'll be cheaper to get singles. 

Check if you're entitled to free or discounted travel on busses. You might be entitled to a concessionary bus pass if you've reached the state pension age, or disabled. 

If you're receiving benefits, then speak to your work coach to see if you're eligible for the Jobcentre Plus Travel Discount Card  which can give up to 50% off selected bus and train tickets. 
 

Rail Cards

If you can, then travel off peak, and book at least 12 weeks in advance of your journey to get cheaper tickets. 

Check the journey on Trainline to see if it is cheaper to buy split tickets. 

If you travel regularly by rail then consider getting a rail card to save on fares.
