The electrical trade in the UK is a real shambles, no professional qualifications required, but still some electricians call themselves professionals, whilst the likes of the SCAM providers exist this will persist, what is needed is a mass resignation from all the scam providers, but it will never happen, I am just grateful that I am retired, spent my last working years in domestic works in France where the legislation is just that legislation, anything beyond the incoming supply is the responsibility of the home owner, no such thing as Part P or EICR, only checks made are on new installations and a cursory check if the property is being sold.
