Egg upping credit limit online

smallbus is dead on there, if you want a quicker answer, (usually within 24 hours) send a secure message from your account online) make sure you give details of other financial commitments but the clincher is saying that you want the increased credit limit to do balance transfers and close other cards down.
The reason for this is you're not then increasing your debt only "managing your money better", (good line to use in the letter/email as it's Egg's mission statement), also make sure you've closed down all old cards with 0 balance as this is considered potential debt and will have an effect on the credit limit you receive.
