Gas bills have several components, and their understanding is key to making an informed choice when comparing tariffs.
This is the amount you pay per unit of gas consumed. This is usually the biggest driver of the total annual cost, varying between suppliers and regions.
A standing charge is a fixed cost per day applied to maintain the pipes, meters, and your connection to the gas network. Even if you use no gas at all, you still pay the standing charge.
Gas prices vary depending on the region because of the different network distribution costs established by regional operators. For instance, gas may be cheaper in the North East compared to London.
Direct Debit usually offers the lowest rates, often with discounts for paperless billing. Paying by cash or cheque tends to be more expensive.
Your tariff can be fixed or variable; this will affect the level of control you have over your rates.
A fixed tariff locks in your unit rate and standing charge for a set period (usually 12–24 months). It provides certainty and protection against future price rises. However, most fixed deals include exit fees if you switch before your contract ends, and you won’t benefit if prices fall.
A variable tariff moves in line with the Ofgem energy price cap, which means the prices could go up or down dependent on market trends. Variable tariffs often have no exit fees, thus giving you greater flexibility to switch if need be.
Fixing can make sense if prices are rising or you want budget stability ahead of winter. Staying on a variable deal can be smarter when the market is stable or falling.
