Gas meter intsallation

So, we’ve just received a letter from British Gas saying they need to change our gas meter. They need us to be home between 8am and 8pm on the scheduled day. Does a requirement of someone being home for 12 hours seem reasonable to you? Particularly when the later half of this cuts straight through dinner time? It doesn’t seem reasonable to me. Surely they can say morning or afternoon?
