credit card advice needed

[Frolicacid]

Hi,
Are there any credit card experts out there who can offer advice about my situation?
I currently have around £11,000 on a halifax credit card. It is all on a 6.9% interest for the life of the balance deal. Interest is around £40 per month. I pay about £50 more than the min payment every month. I also have an empty mbna card with a limit of £14,000 which is offering 0% interest until sept 2015.
I can't decide what to do about transferring to mbna. Obviously I know it makes sense to pay as little interest as possible, but I'm worried about what happens when the 0% runs out. mbna's 'normal' rates are a killer.
Does anyone know if halifax are likely to review my limit / cancel my card and leave me potentially stuck without anywhere to swap the balance back to?
Maybe transferring half the balance would be a good idea, leaving me with the other half to transfer back and forth ifykwim?

Applying for another credit card / loan are not an option at the moment.

TIA

6.9% is a very good interest rate for a credit card. Looking at the Halifax offer today, their typical card charges more like 18.9% interest. If you transferred the balance, I doubt you'd get 6.9% again.

If you switch to a 0% card there is usually a percentage balance transfer fee for doing so. So you have to factor that in as well as the eventual interest rate when the 0% expires. If the transfer fee is 3%, for example, on a balance of £11,000 your new debt would go up by £330 - the equivalent of eight months interest. Not saving you very much at all really

Is £50 over the minimum payment the most you can afford?

Thanks cogito. Put that way it makes sense not to move from the 6.9% I wouldn't save that much over the 12 months and it's not worth the risk of then being stuck with a lot of money on the standard mbna rate of around 26%. I'm due a pay rise next month, so will have more to put towards it then.

Thank you talkin as well. Will have a look at the spreadsheet.
