Buenchico is correct in that the relevant authority for such complaints is Trading Standards.
Before you invest your life�s savings in your quest to rid the country of dangerous tools � I would offer the following advice:-
Pick the single worst example you have seen, and complain to Trading Standards � pointing out that your main purpose is not to gain a refund, but to ensure that the dangerous goods are taken off the market and/or the manufacture/importer of the goods are fined.
Just because a tool is crappy, does not necessarily mean that it is unsafe. Even if a fan breaks up, this does not mean that it is unsafe, if the parts cannot cause injury.
See how you get on, if successful, present them with another unsafe item.
Trading Standards are tasked to deal with consumer complaints concerning a multitude of areas. It is very unlikely that they will have an expert in the area of product safety. To some extent, this reflects the low priority successive governments have given to ensuring the safety of products sold within the UK � perhaps with good reason.
With regards fatalities from electric shocks, around 10 people a year die in the UK. When each of these incidents is analysed, around 9 of the 10 were doing something dumb, such as connecting their bathtub to the plug live terminal. In comparison, 10 people a day die on our roads. Although even one death, is one too many, especially if it is you.
