Here's mine for the past 10 years. Goldshield, Nightsaver, 3 bed terraced townhouse with storage heaters (winter) & immersion (all year) on overnight. The spike at the end is skewed by arrears that I omitted to pay when due.
Update 19th July 2007: just to clarify that the data points represent two monthly billing periods.
Updated again 5th January 2008 to add breakdown of different cost components.
Yeah €50 a month for a 1 bed seems about the average, in my apartment i noticed while fitting the washing machine their is only one connection for water going into the washing machine. Apparently the hot water tank has no connection pipe going into the washing machine, so i have to use a dual connecter from the cold tap and plus buy a washing machine that heats the water.
I pay (now, don't mention the war) €55 a month for a 4 bed mid terrace with GFCH.
GFCH costs me an additional €40 per month, that's averaged over the year for both
