British homes will send an average of £5,700 abroad to foreign gas producers to heat their homes and water and cook food by the middle of the next decade, new analysis suggests.
The average home could be buying foreign gas worth around £500 a year by 2035, unless efforts are made to reduce the country’s dependency on gas.
The Energy and Climate Change Intelligence Unit (ECIU) said that it would not be possible to avoid this by producing more gas domestically, as the UK’s North Sea reserves are dwindling.
Without this, it warned homes across the country will become even more dependent on imported gas to function.
The UK currently imports around half its gas, but that could rise to 85% by 2035 without the alternatives, the ECIU said.
The perils of relying heavily on imported fossil fuels became clear last year after Russia launched a full-scale attack on Ukraine.
Russian gas supplies to continental Europe dried up following the invasion, pushing prices up more than tenfold at times.
European countries were also worried that they could run out of gas if they faced an unusually cold winter. As it turned out the winter was mild.
The UK did not get much of its gas directly from Russia. But because it is part of a Europe-wide market, it was just as impacted by soaring prices and supply concerns as countries on the continent.
By comparison, a home with a heat pump, solar panels and good insulation could be spending just £10 a year on gas by 2035 if the deployment of renewables speeds up across the country.
“You can’t squeeze much more out of the North Sea; its output has been declining and the official numbers show that’s going to continue. It’s simply running out of gas,” said Dr Simon Cran-McGreehin, head of analysis at ECIU.
“Those arguing against heat pumps are arguing for UK homes being more dependent on foreign gas.
“And with wholesale gas prices predicted to stay two to three times higher than before the crisis, that means being dependent on an expensive fuel.
“The Government has some of the right targets for UK energy independence, but not the policies to deliver on them.”
A Department for Energy Security and Net Zero spokesperson said: “This analysis fails to take into account the plans we have in place for powering up Britain, including significant investment in new renewable and nuclear projects. All this is backed by billions of pounds of Government funding, leveraging around £100 billion in private investment.
“This is on top of our commitment to invest £6.6 billion in energy efficiency upgrades this parliament, with a further £6 billion to 2028. We have upgraded around 2.4 million homes through our Energy Company Obligation scheme alone, while our Boiler Upgrade Scheme enables consumers to purchase a heat pump at an increasingly comparable price to a gas boiler.”
