Hi S123,
Me personally, I think it may be best waiting until the budget on the 26th March. A lot of speculating can mean unneccessary worrying. I'm sure after the budget, Steve will publish a newsletter explaining all the changes. I would also recommend watching the Martin Lewis money show on ITV at 8pm - usually a Tuesday but odd times a Thursday, as I imagine he will be receiving a lot of complaints, and concerns that he will try help address for people.
Chris.
