Top 10 Gas Providers in the UK

Gas is metered in the UK, which means that customers only pay for the gas they use. However, central heating prices can vary considerably. This is because there many different suppliers, and they all have their own tariffs and central heating costs. Knowing which supplier is the best, and the cheapest, is not always easy, but doing a little bit of research can really pay off.

Many people save large amounts of money on their gas bills by switching suppliers, so it pays to know what the various companies are offering. Many of these suppliers also provide and install central heating boilers. If you are looking for a new boiler quote, or you would like to compare boiler prices, it is a good idea to get more than quote. Researching energy suppliers and asking around for details on installation and maintenance is always recommended.

Here, listed alphabetically, is a quick introduction to ten of the biggest UK gas providers.
