The Government publishes Energy Trends statistics, including for gas, at: https://www.gov.uk/government/statistics/gas-section-4-energy-trends. Table 4.1 shows production, total imports and demand. Table 4.4 shows import countries of origin.
The UK gas market is one of the most liquid and developed markets in the world and provides security through diversity of supply. Most of the gas supply to the UK comes from domestic production (46 per cent in 2019), as well as imports from reliable suppliers like Norway (31 per cent in 2019). The remaining 23 per cent of supply was from pipeline imports from the Netherlands and Belgium, as well as Liquefied Natural Gas (LNG) from a diverse range of sources. There are no gas pipelines directly linking the UK with Russia.
In 2019, one-fifth of UK supply was from LNG. Within this, around 34 TWh of LNG was imported from Russia, representing less than 4 percent of the total supply of gas to the UK. The UK is in no way dependent on gas supply from Russia and our LNG was sourced from 12 different countries last year.
