The British Government is imposing an immediate moratorium on fracking, saying the industry risks causing too much disruption to local communities through earth tremors.

Prime Minister Boris Johnson's Conservative Government had previously signalled its support for the shale gas industry as it sought ways to cut Britain's reliance on imports of natural gas, which is used to heat about 80 per cent of Britain's homes.

But fracking, which involves extracting gas from rocks by breaking them up with water and chemicals at high pressure, is fiercely opposed by environmentalists who say it is at odds with Britain's commitment to reduce greenhouse gas emissions.

The announcement comes as Mr Johnson gears up for an election on December 12.

"Exploratory work to determine whether shale could be a new domestic energy source in the UK … has now been paused — unless and until further evidence is provided that it can be carried out safely here," the Business and Energy Department said in a statement.

The decision follows a report on an incident at a site run by British energy company Cuadrilla near Blackpool, northwest England, where a magnitude-2.9 tremor shook houses in August.

An anti-fracking campaign by local people emerged as a flashpoint in a growing climate activist movement opposing new fossil fuel projects around the world.

Hundreds of protesters have been arrested over the past few years for trying to disrupt Cuadrilla's operations.

Fracking in England only resumed last year after two tremors prompted a seven-year moratorium.

The Blackpool incident was examined by the Oil and Gas Authority (OGA), which regulates and promotes Britain's oil and gas industry.

Its report found it was not currently possible to accurately predict the probability or magnitude of earthquakes linked to fracking operations.

The energy department said it would not take forward proposed planning reforms for shale gas developments.

"After reviewing the OGA's report into recent seismic activity … it is clear that we cannot rule out future unacceptable impacts on the local community," Business Secretary Andrea Leadsom said.

Other sources of natural gas would continue to contribute to Britain's energy mix, she added.

Britain has set itself a target of becoming a net-zero carbon producer by 2050.

Cuadrilla is 47.4 per cent owned by Australia's AJ Lucas, while a fund managed by Riverstone holds a 45.2 per cent stake. There was no immediate comment from the company.

Environmental campaign group Greenpeace welcomed the ban.

"It's been clear for some time that the Government's big bet on fracking is bust," it said.

"This lesson now needs to be applied to unlock onshore wind and solar, and significantly ramp up offshore wind."

Fracking has also been controversial in Australia, with protesters campaigning against the technique's use in Western Australia and the Northern Territory in recent years. Victoria became the first state in Australia to permanently ban the technique in 2017.
