Those rates are good. Competition is a good thing.
I switched from Airtricity to Bord Gais yesterday, just for electricity 24hr urban. Based on the figures quoted, I got a better deal.
Energia's 16% discounted rate ex vat of 0.139 beats my Bord Gais 10% disc rate ex vat of 0.1465 and applied to my annual usage of 2,300 kWh works out as €17 cheaper with Energia. Energia's standing charge urban is €11 dearer than Bord Gais.
Energia +17
Bord G -11
difference + 6
Bord G -50 Tesco voucher
-44
I am better off by €44 because of the €50 Tesco voucher, but my annual usage is fairly modest at 2,300 units per annum.
