OK, I'll add my 2p worth.
#1 No idea. Try asking in the Computers & Internet forum.
#2 - Check out the websites for Orange, BT, Vodafone & O2. That should give you some idea of the relative cost per month of a subscription.
#3 Many insurance companies will do House, House Contents and car insurance. We have all our insurances with one company and get a discount for it. Finding an insurance company is not a problem.
#4 If you are going to be PAYE, Pay As You Earn, then your employer will deduce your tax at source. If you are self-employed, you will lhave to sort out all your contributions yourself. Most PAYE people never fill out a tax return.
#5. We have a culture of buying our houses. That doesn't mean that there is anything wrong with renting, its just that we tend to buy houses rather than rent them.
#7. The south is more crowded than the north. That should give you a clue.
