Today marked the implementation of new price hikes for Electric Ireland and SSE Airtricity customers while in just 24 hours, similar increases will be seen from Bord Gáis Energy.
Homeowners were encouraged to submit their most up-to-date meter readings to avoid paying the fee for the highest tariff - so they would only be paying for what they actually use.
As a result of the rush, the SSE Airtricity website crashed on Friday afternoon as thousands of customers tried to submit their gas and electricity readings online before new higher prices kicked in.
