I have just opened a bank account with Nat West. This is called the ADVANTAGE GOLD current account. It costs £12 a month but you get- Mobile phone insurance, Purchase Protection, Extended Warranty on electrical goods, Identity Theft protection and most importantly TRAVEL INSURANCE COVER for me and Carol including CML.
I was asked 4 questions relating to pre existing conditions. I am now covered worldwide and so is Carol after her spinal/neck fusions.
I suggest if you are interested ask Nat West for a brochure on this account then before opening an account phone up the travel insurance section. Get a reference number and when they say you are covered then open the account. Its cheap at half the price.
Good luck.
P.S. If you take out the cover make sure you get a confirmation in Writing. I had to ask several times for the confiramtion.
