The energy policy of the United Kingdom refers to the United Kingdom's efforts towards reducing energy intensity, reducing energy poverty, and maintaining energy supply reliability. The United Kingdom has had success in this, though energy intensity remains high. There is an ambitious goal to reduce carbon dioxide emissions in future years, but it is unclear whether the programmes in place are sufficient to achieve this objective. Regarding energy self-sufficiency, UK policy does not address this issue, other than to concede historic energy security is currently ceasing to exist.

The availability and uptake of green electricity in the United Kingdom has increased in the 21st century. There are a number of suppliers offering green electricity in the United Kingdom. In theory these types of tariffs help to lower carbon dioxide emissions by increasing consumer demand for green electricity and encouraging more renewable energy plant to be built. Since Ofgem's 2014 regulations there are now set criteria defining what can be classified as a green source product. As well as holding sufficient guarantee of origin certificates to cover the electricity sold to consumers, suppliers are also required to show additionality by contributing to wider environmental and low carbon funds.
Energy switching services are companies that have come to exist since the EU began deregulating the gas and electricity markets, to open them to competition, in 1996. Progress has been uneven across member countries, but in the UK there is now open competition among suppliers. Pricing structures and special offers are often complicated enough that it's not obvious which supplier and tariff will be best value for a consumer. This has provided an opportunity for specialist price comparison services. These are chiefly offered by companies who will manage a change to a different supplier and tariff, as well as advising on the best one. These companies primarily operate over the Web, although some also offer a telephone service.
