Buzzy - read this link - especially further down. It is much more useful than anything the Daily Mail says.

The point is that EU Directives are just that. They are not binding on member states. What happens is that member states are then required to implement national law to implement the intention of the Directives.
In the UK, it was implemented in the Sale and Supply of Good Regulations 2002. If you read towards the bottom of my link (remedies), you will find that crucially the UK did not build this 2 year rule in - instead we used the weasel words 'reasonable time'. The whole D Mail article then gets muddled in the business about the 6 year statutory limit. This is the time within a civil claim must be made - not the implication that a product was work for 6 years.
By all means try quoting the EU Directive - I don't think it will wash with Comet.
You are covered by the SSG Act 2002, then this doesn't give you the rights under the EU Directive. It doesn't change anything that you bought one of those hideously expensive 4 year insurance policies.
