The main train operator serving Brighton and Hove said that fares would rise by an average of 2.1 per cent in the new year.
Southern said today (Friday 5 December) that this would be the average increase across all fares and would come into effect on Friday 2 January.
Regulated fares for next year, which include season tickets, have been capped by the government at the July inflation Retail Prices Index rate of 2.5 per cent.
The company said: “Our cheapest Southern £5 Advance fares will remain frozen for the eighth consecutive year and many off-peak Gatwick Express fares will be frozen at 2014 prices with additional discounts online.”
Southern’s commercial director Alex Foulds said: “This is great news for those looking for cheap off-peak travel as we continue to freeze our cheapest Southern online Advance fare at just £5 for the eighth consecutive year.
“Gatwick Express passengers will also benefit as we are freezing many non-season ticket fares on the route.”
