Hi,
I think that the following sites are a useful starting point. However, I would advise that you speak with a qualified FSA approved financial advisor to dicuss your individual situation and requirments.
www.unbiased.co.ukFind an independent financial adviser in the UK. Search by postcode.
www.moneysavingexpert.com/mortgages/Martis Lewis (of GMTV fame) provides some excellent consumer advice. He produced a guide along with London & Country (although the advice is unbiased so well worth a read).
Does anybody else have any recommendations?
