Based on my bills (so, obviously dependent on the tarriff I was/am on)
Gas with Bord Gais:
January 2008: 4.509c per kWh + Standing charge 13.7c per day
December2008: 5.471c per kWh + Standing charge 14.3c per day
January 2013: 5.193c per kWh + 0.37c carbon tax per kWh + Standing charge 21.7c per day (applies on most recent bill too)
I'll dig out the electricity charge in a few minutes.
But looking at my figures above... The charge for gas usage at the moment is roughly the same as December 2008 (adding together the usage and the carbon tax).
Compared to January 2008 however, the charge is up about 25%-30%.
The standard charge is about 50% more than it was.
