I understand there will be costs incurred by the homeowners or landlords but surely as sparks we should all be thinking along the line of raising standards in domestic properties, it would be hard to police and make sure all circuits tested etc if it saves lives then I'm all for it, or even if it became compulsory to have one done before you can sell your house? Or every 10 years just to check everything is okay? Some of the houses I've worked in over the years have been death traps due to people adding things on and not knowing what there doing, this could prevent someone being killed hopefully.
