Possible options for decent savings without an address history?

I've been poring over the various opportunities regarding salting a fair sum of money away in exchange for differing returns on this website, but one thing that seems to be standing in the way is my address history, as it has been extremely chequered over the last six years due to personal circumstance.

I cannot thus provide three years worth of address details, sadly (evidenced by my attempt to secure a credit report from experian).

I'm wondering if i've missed a trick or two hunting for a viable option in savings, or do i quite simply need to stay put for the next few years in order to rebuild my credit history? It seems like this is the most obvious answer, but my financial savvy is most certainly not the most spectacular. I've looked at the option of cash ISAs, although I'm wondering if anyone other than my own bank would offer me such.
