At one point I changed all my account addresses to Thailand. However, I received letters from several of my investment fund manager's requesting translated and certified copies of my foreign ID card plus other proof of living abroad. I sent photo's of my pink ID card and ignored the rest of the requirements. One wrote back saying what I had provided wasn't acceptable. One company suspended my on-line access for dealing. I changed everything back to my UK address and all was reinstated. Stopping using my Halifax Clarity Credit card was approximately 12 months later. I telephoned their customer services to ask the reason for reducing my credit limit from 10,000 GBP to 500 GBP. I was told it was simply lack of use. No mention was made of my previously having an abroad address. Of course, I didn't bring that up either!
