We've all seen adverts urging us to switch suppliers of electricity, gas, and telecoms. They promise big savings, especially those trying to get us to switch to a single supplier for electricity and gas. Are there really savings to be made? The answer is yes, for the moment, and it may be less difficult to switch than you think. Even if you don't want to switch, you may still be able to reduce your bills. Phone companies may also provide Internet and cable television access. Before buying or changing, decide what you need and what you're prepared to pay for it.
