Unless you intend to switch to a fixed rate deal I'd suggest you sit tight for a few more weeks as energy providers tend to follow each other in raising/dropping prices, and it will be annoying to have switched to another who then raises their prices! So far SSE and Electric Ireland have given notice of prices increases and it is won't be long before others do too.
Insofar as Electric Ireland is concerned their website switching terms and conditions [] has no clawback provision, so it would appear it is yours to keep.
