Sorry if this has been discussed but couldn't find any clear answers.
I got a qualified electrician to install an extractor fan in the kitchen (which required connecting it to the electrical circuit through the ceiling). I asked the electrician the next day whether he would give me an installation or minor works certificate. His answer was that he would need to visit the house again for this and therefore charge me £38 more.
Should I have expected a free minor works certificate when the installation was completed? Do the UK electrical regulations require him to provide one?
