If a law was passed whereby the fitment of a 13A plug to an appliance in your own home was made illegal unless you sent away a cheque to your local authority then until that law became widely known then you'd expect Currys etc to carry that warning when buying an appliance with none fitted.
That's a bit irrelevant - all appliances now must come with a 13A plug fitted and if you buy a replacement plug retail packaged most of the time in the instruction leaflet it already says to consult a qualified electrician if you are unsure. I'm sure this same leaflet could carry the notification warning.
So then would it be up to the manufacturer, who supplies that instruction leaflet to inform you of the legality of using their product? Has anyone read the instruction leaflet that comes with a B&Q consumer unit? It will probably mention something about the law regarding its use.
Although this could get confusing when an item is supplied to the whole of the UK, as the laws are different in Scotland. It's a bit silly telling people they must comply with Part P regardless of where in the UK they live.
In fact, looking at this leads me to believe that installing a new consumer unit in a house up to 2 stories in Scotland does not require a warrant. And most people live in a house up to 2 stories don't they? So then the supplier/manufacturer can sell one with a clear conscience knowing that the majority of the time it is used by DIYers within the regulations.
