Found a number that looks wrong? Tell us which article and what your own bill says. Corrections go out the same week, because a site whose whole value is accurate arithmetic cannot afford to sit on one. Our method is published if you want to check the working first.

We cannot advise on your own wiring, your own hot water system or your own contract. For those, a licensed electrician or your own retailer looking at your actual bill will beat anything we can tell you.

We do not take payment from energy retailers and we do not sell introductions to them.
