Urgent Query!!! Spain-UK Money Transfer

Hello,

Please can anyone recommend the most cost-effective way to transfer around 10-12,000 euros from a Spanish bank (La Caixa) to the UK. Transferring money directly from La Caixa into a UK bank would incur unfavorable rates and commission. La Caixa's rate for SEPA payments with full data identification is 0.40% of the transaction amount.

Please help.

I didn't find the right solution from the Internet.
