To make sure you’re not paying too much for your household energy.

If you’ve never switched supplier before, you’ll be on a standard variable rate (SVR) tariff, which will come with higher rates than other deals on the market. You’ll also be on an SVR if you’ve previously switched to a fixed rate tariff but have let it expire without switching to another deal.

Energy suppliers make money from your apathy to switching, so it always pays to compare energy suppliers and switch when your current deal is coming to an end – CAfS can help make sure your money stays in your pocket.

Being on an SVR also means you’re fully exposed to market fluctuations – if energy prices rise, so will your bills, even if you’re not using any more gas and electricity than normal. Back in the summer of 2008, for instance, the market was hit by price rises of 35%, which saw standard variable rates increase by a third overnight. Although it’s unlikely we’ll see another spike like that, it’s best to protect yourself against any price rises by switching to a fixed rate deal.
