Airtricity agent who sold us the gas and electricity service never mentioned the cost of standing charge when saying their Budget Plan is the cheapest on the market. When I asked about the standing charge over the phone I was told that they don't set up the standing charge as it is set up by the government. This is simply not true as companies can still decide how much they charge and different providers charge differently. It took me at least 20 emails and calls to get some information form airtricity on how they calculated a fixed rate for my plan. It looks like on the Airtricity Budget Plan they simply charge everyone 140 even though they claim it's estimated based on your past individual usage.
