Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, if she will make an estimate of the potential impact of trends in the level of imported energy on the cost of energy for (a) domestic and (b) business customers in the last five years.

The main driver of trends in energy prices for domestic and business customers over the last 5 years has been movements in international gas prices, which determine the amounts charged for both domestically produced and imported gas. The Department publishes data on the UK's overall net imports, with separate data on imports of gas and other energy products, alongside energy prices. Developing more home-grown sources of energy supply – including renewables – will help reduce the exposure of UK energy prices to volatile international markets.
