I have just moved into my first new home and its a bit of a mess. It has been suggested that I have the main electric consumer unit upgraded. I have been quoted £400 + Vat. Can someone tell me whether this is an Ok quote. Additionally, some old electrical boxes stuck to the wall for an old cooker, an old shower and an old alarm system no longer there. Can these be ripped out? Do I need an electrician, what are the likely costs please? I also need an alarm system and shower installing, do I buy these myself and get an electrician to install them ??????? ARGH!!
