We have a booster plugged in upstairs which extends the range from this little office all the way up to my bedroom at the other side of the house - you just plug it in to a spare socket. Hive also recently sent us one as they must have seen that our system wasn't being picked up on anything - it just arrived in the post and worked right away. You can pick them up in most electrical places like Maplins
