Thanks for the advice guys, Spoke to halifax today and got sorted - reduced the Reg Saver to 100 pm and I got to open the updated 350 pm account at 7% but this is due for review in June/July, so watch out!
They have a new fixed rate 5% for one year 4.5% for two years, which might be worth a look.
I already have the reg. saver with FA and am using Hal flexi at 5.15%, I think, but I feel I would likje another 7%ish regular account as well, suggestions welcome.
