The Government has unveiled exactly how much households will pay for energy from October 1.
Last week Prime Minister Liz Truss announced the typical household energy bill will be capped at £2,500 a year on average from October.
But that figure is a rough average, and now the Government has revealed exactly how much households will pay.
Under the new Energy Price Guarantee, the typical house will save an average of £1,000 and the average flat will save £700.
The typical detached house will pay £3,300 in gas and electricity bills a year from October 1 - saving £1,400.
An average semi-detached house will pay £2,650 a year, the Government said.
End-of-terrace homes face bills of £2,450 a year on average, mid-terrace properties £2,350 and bungalows £2,450.
A converted flat will pay £1,950 on average for one year of energy, and a purpose-built flat around £1,750.
How much you pay will vary depending on your energy deal and how much power you use.
To find out your personal energy bill, the Government has also published how it will cap unit rates for gas and electricity.
These will be 34p per kWh for electricity and 10.3p per kWh for gas.
Standing charges will be 46.36p per day for electricity and 28.49p per day for gas.
Speaking on Twitter, MoneySavingExpert founder Martin Lewis said: "They will also likely be a few percent higher for those who pay by direct debit or on receipt of bills."
The above all applies to homes on variable rate energy deals - about 85% of the country.
If you're on a fixed tariff at a higher rate caused by recent energy price rises, your unit prices will be reduced by 17p/kWh for electricity and 4.2p/kWh for gas.
The Ofgem price cap only applies to people on variable rate energy deals - around 85% of the country, or 24million people.
But many energy users have recently locked in to fixed rate deals and may not benefit from any price cap freeze.
This price cap was due to rise to £3,549 in October.
Because of that, up to 15% of households have taken out fixed rate deals higher than the current price cap, thinking it would save them money in the long run.
The Government has said these customers will get the same sort of help as those on variable rates - but has not yet given details of how this will work.
For pre-payment meter customers, the Energy Price Guarantee will be applied to the rate you pay for each unit of energy.
That means any money you put on the meter will last longer than would otherwise have been the case this winter.
But pre-payment customers will still pay more for their energy than other bill payers.
The average unit price for dual fuel customers paying by direct debit will be limited to 34p/kWh for electricity and 10.3p/kWh for gas from 1 October.
Energy suppliers will adjust standard variable tariffs automatically.
Those households not on standard gas or electricity contracts, such as those living in park homes or on heat networks - and so outside the scheme - will be no worse off and will receive comparable support through a discretionary fund.
Your landlord is not allowed to profit from selling you energy.
The Government says landlords should speak to their tenants to "come to an agreement" about the cost of energy.
This is clearly quite vague, but the Government says emergency new laws may be passed to clear this point up.
