We are returning permanently to the UK

What are the tax implications in both countries of us renting out our house here (we would rent in the UK so this would be our only owned house)? The rental income would just about meet the mortgage we still have on it so we wouldn't be making anything. (We just can't sell it in this climate - too many new houses being built).

If we sell it later at a profit can we offset the huge loss we made when we sold our rental property here?

How can we get our SMSF out of here, since otherwise they will keep taking 15% a year from it until there's nothing left.

Which superannuation funds in the UK will accept work pensions from here, (GESB and Hesta)?

Thanks.
