Is it permissible to replace a bathroom fan (no new wiring) without requiring part p certification?
also I noticed the advice for a bathroom isolater switch (on a new fan), but my existing bathroom (with fan) does not have an isolater switch. The fan is actually fed of the lighting ceiling rose in parallel - along with the shaver outlet (which took me a while to figure out!). Is this bad practice? would it pass an inspection now? (my house is only 10 years old!)
