Hi Solac

If you look under the 'contact us' page on the Yorkshire Bank website you will find:

"Internet Banking
To contact the Internet Banking Helpdesk phone 08456 000 333.

For customer's outside the UK phone +44 141 951 7315 and select option 0.

The Helpdesk hours are:
Monday - Friday: 8.00am - 10.00pm
Saturday & Sunday: 9.00am - 6.00pm"

Therefore from the UK dial 0141 951 7315. I presume they are based in Glasgow from the area code.

Hope this helps.

Thank you very much, contacted them fine
