I agree that the 'unbundled' price scheme is now accepted across the UK. I often refer to this method by using the name of a well known LCC ... The car industry has used this for years and steadily moved the 'striking point' as low as they can. We will not see a return to a fully bundled pricing scheme for many years - although it WILL happen. But, for the moment, we already have 30 years worth of customers used to this way of pricing.
We see the same method used by politicians with what are now called stealth taxes. They do not want to increase basic tax rates but need to raise more tax, so they charge for things that were previously free. Local govt have been forced down the same path.
