Prime Minister Liz Truss has announced plans to cap average household energy bills at £2,500 a year from October
The support will last for two years, she announces in the Commons, saying "this is the moment to be bold"
A typical household's gas and electricity bill had been due to rise from £1,971 to £3,549 in October
Businesses are also getting a support package for six months which will provide "equivalent support"
After the six-month period, further support will be targeted at "vulnerable industries", Truss says
The government is also lifting the ban on fracking - which involves extracting gas and oil from shale rock
Our coverage of the government's plan to cap energy bills is coming to a close.
During the debate, a statement from the Palace saying that the Queen is under medical supervision was released.
With the debate drawing to a close, here are the main lines from Liz Truss' announcement on energy bills.
As expected, an energy bills price cap of £2,500 for the typical household per year, for the next two years, has been announced.
A six-month support package for businesses has also been announced, with further support for "vulnerable industries" after that period.
The ban on fracking will also be lifted - allowing developers to seek planning permissions where there is local support.

Susan lives near a fracking site in Lancashire, she's concerned about the government's plans to lift the ban on fracking.
"I've experienced huge methane emissions, earth tremors and the disruption that comes with a fracking site," she says.
"For me, health and peace of mind are far greater value [than cheaper energy costs]."

Philip in Croydon would like to see the government nationalise "all sources of oil and gas in UK territories".
"We've nationalised the pain, so nationalise the profits," he says.
"If we take control of our own national resources, we could have a proper domestic energy market... we should look after our own people first."
Ronnie in Hemel Hempstead believes there's "hypocrisy" in the government's plan to borrow money.
He says when David Cameron came into power "we were told borrowing at the levels being spoken about would destroy our grandchildren's futures".
"We were told the borrowing [Labour were proposing at the lest general election] they were talking about would lead the country to economic ruin, but when the Tories want to borrow at this level now, it's fine."

At its heart is a move to limit the 80% rise in domestic bills that was earmarked for October.
So how much will you pay? Will you have to pay it back? And will you still get cost of living payments?
Image source, PA MediaTruss' first major decision would be to protect the profits of big businesses, Blackford continues.
He's describing the funding for this plan as a "Truss tax", adding that the decision to not increase a windfall tax is the worst decision she could possibly make.
There is a difference between fair and an excess, or windfall, profits for companies like Shell and BP.
Blackford criticises energy generation firms for paying dividends and buying back their own shares with these profits, rather than investing in infrastructure.
More now from Blackford, who says the current system isn't fit for purpose and needs urgent review.
He says businesses are facing a fight for survival and the UK government needs to grasp the scale of the emergency.
In reality, the one big question is how it would be paid for and who would pay for it, Blackford says.
He adds the prime minister has made a political choice to ask families to fund it, rather than businesses.
Heading back to the energy debate now, and SNP leader Ian Blackford - who has sent his best wishes to the Queen following the news - is warning about impact of high energy bills.
Blackford says this cost crisis puts lives and livelihoods at risk, but that people were left waiting all summer
Blackford adds the plan that we've finally heard today falls short of what is needed to address people's costs.
He says freezing prices wasn't a choice, but the only political option and setting the cap at £2,500 isn't a freeze, but baking in high prices.
Speaker of the House Lindsay Hoyle has just interrupted the energy debate, to say he and the House are sending their best wishes to the Queen - following an announcement that the monarch is under medical supervision at Balmoral Castle.

Consumer support is as expected. A typical household will see their energy bill rise to £2,500 in October which will be fixed for two years.
A £400 rebate takes it down to £2,100. Additional payments of £650 for those on qualifying benefits will also stay in place. But there is no suggestion those payments will be repeated so average households will see an energy price rise of over 25%.
Businesses offered "equivalent support" for a six month period but it is not clear what that means as they have not yet published the unit cost per unit of gas and electricity that they are using to generate the domestic cap and cannot yet confirm whether the same unit cost will be applied to business customers.
Business will need greater clarity on this if they are to be reassured.
Conservative MP Theresa May says the energy efficiency of homes needs to be improved, as it would not only reduce demand for energy, but would also help to save the planet.
We do need to consider rolling out significant home insulation programme, she adds.
Former PM Theresa May congratulates PM Liz Truss on acting so swiftly on energy bills.
She welcomes the fact that energy bills action has been coupled with action on energy security.
"The vicious invasion of Ukraine by Russia has indeed shown the necessity of us having our own energy security," she says.

There is a real ideological divide between this new Conservative leadership and Labour’s.
Keir Starmer calls Liz Truss’ opposition to windfall taxes on oil and gas firms “ridiculous”, but the Tory front bench has definitively ruled out any more taxes.
Starmer himself calls this the big “divide.”
It’s a contrast to Boris Johnson’s cabinet — who did end up introducing the current windfall tax.
Image source, PA MediaBritain needs a fresh start, not a government who protect the profits of energy companies and doubles down on fossil fuels, Starmer says as he ends his stint at the despatch box.
The change we need is not the fourth Tory prime minister in six years, but a Labour government, he concludes.
If all countries took the approach of squeezing every single drop out of their fossil fuel reserves, that would be devastating for our planet, Starmer says.
Wind and solar are now nine times cheaper than gas. So we need a clean energy plan, urgently accelerating the rollout of offshore wine, onshore wind, solar, nuclear, hydrogen and tidal.
Starmer says fracking and a dash for gas in the North Sea will not boost our supply in the short term or energy security.
But he adds it will fight our ability to reduce greenhouse gas emissions and stick to net zero commitments.
He then reads out (lengthy) quotes from Chancellor Kwasi Kwarteng a few months ago, where he argued that fracking and North Sea oil would not reduce wholesale prices.
Starmer says doubling down on fossil fuels is a "ludicrous" answer to an energy crisis, given the threat that climate change poses to the planet and future generations.

We're thick into the debate in the Commons now.
But many of you will be wondering: what happens now?
Greg Jackson, chief executive and founder of Octopus Energy, says: "Companies and government are now working through the details and customers should sit tight and wait to hear from their energy supplier.
"Nothing will change until 1 October and we'll be in touch with everyone before then."

The prime minister said a fund will be created to support those who are not covered by a cap.
This includes people who use heating oil in their homes, those who have communal heating schemes, and people in mobile home parks who pay the park-owner rather than a supplier.
More details will come later, but this will be an extremely complex task.
For example, people in park homes do not yet know how they will receive the £400 discount available to everyone – and that was announced months ago.
Expect debate over how people get this money, and how soon.

The real question before the house today the government faces, the political question, is who is going to pay?
The Treasury estimates that energy companies could make £170bn in unexpected windfall profits over the next two years.
The head of BP has called this crisis a cash machine for his company, and households are on the other end of that cash machine, their bills are funding these eye-watering profits, says Starmer.
"That's why we've been calling for a windfall tax since January, and it's why we want to see it expanded.
"The consequence is the bill will be picked up by working people."
Repeating arguments he made at Prime Minister's Questions yesterday, the Labour leader says Liz Truss is opposed to windfall taxes and wants to leave vast profits of energy companies on the table.
He adds the bill will leave working people footing the bill.
Starmer says there is no reason taxing these profits that have come about via market price spikes rather than planning would deter investment.
He says her argument against it falls apart at first inspection, adding she is driven by dogma.
