Kildare households could save €2k a year by switching providers Reporter: '); More than 36,000 households in Kildare are missing out on savings of up to €2,000 in energy costs per year by failing to switch providers, a new survey has revealed. Those living in bungalows or detached homes across Ireland can benefit most by trading in their current supplier for a new one, according to the WeSwitchU.ie Index. The index shows the gap between the cheapest and most expensive plans on the market — with a €2000 annual difference between some dual-fuel plans for these house types. For semi-detached homes the index reveals savings of €800 for dual-fuel customers (€2,250 versus €1,450 per annum), and €620 for apartment or terraced-house residents (€1,600 versus €980 per annum).
