Hi Dan, When you say heater switch at the consumer unit do you mean the mcb on your consumer unit? Sounds like it could be a loose connection.You will need to get an electrician to look at before it develops into something more major. Shouldn't be a big job if you sort it quickly but don't leave it.If it is a loose connection it could end up burning the cable or even start a fire so get it checked out to be on the safe side. Hope this helps Russ
