The new number, 0344 372 1892, is live now and has been introduced following feedback from supporters.

The 0344 local rate number replaces the prefix 0844, which carried a cost of 7p per minute plus callers’ network access charge.

The old number will remain active for a short time and fans will be advised to hang up and call back on the lower cost number.

Nicole Atkin, the club’s head of business development, said: "We’re delighted to launch our new low cost number, which should dramatically reduce the cost of calls to the box office for fans.

"It’s vital we listen to supporter feedback and we know it has been a frustration that our 0844 number carried significant charges from some mobile network providers.

"Although the network charges were not applied by the club, calls to our box office are essential in delivering a host of supporter services and we wanted to ensure this remained affordable for our fans.

"Together with our investment into our online platforms and information services, we hope that our new low cost line will help to enhance supporter experience overall and show fans that we are listening."

To contact the club, please call 0344 372 1892.

Calls cost no more than calls to geographic numbers (01 or 02).

According to Ofcom, calls from landlines and mobiles should be included in free landline and mobile call packages.
