NPower is offering existing customers the opportunity to fix energy prices for free until March 2009. If you believe fuel bills are going to keep going up and up then it could be worth exploring such deals further. At least you’ll know apporximately what your monthly outgoings will be. Whether it’s with NPower or another provider, double check at what prices energy costs will be fixed at. It may well be that an increase is already factored in to the fixed rate price and so you’re paying more in the short term to compensate for the fix.
