Bus fares are going up across all of Norfolk's routes.

First Eastern Counties announced at the start of the month a number of prices will be frozen while others will rise on January 11.

Tickets will increase by as much as 14pc, with season ticket-buyers - particularly those aged from five to 19 - being the hardest hit.

First said it had kept the increase to as low a level as possible to cover cost increases including fuel, which it had no control over.

Chris Speed, head of operations at First Eastern Counties, said: "Over the past 18 months we have expanded our bus network and invested in upgrading our fleet to improve public transport provision in the city and county with further plans to develop our offering to bus users over the coming months.

"These improvements show our commitment to delivering a sustainable bus network for local people."

In all zones the 10-trip ticket, which allows passengers to travel 10 times in a 28-day period, will only be available on its mobile ticket app.

To speed up services, return tickets will no longer be available in the Great Yarmouth Town Zone, Lowestoft Town Zone and Explorer Zone.

Here are the changes for each zone in the city:

Inner Zone Day ticket

Day ticket prices will increase between 10p and 30p for adult, young person and High5 group tickets on the inner zone for both mobile and paper tickets.
