Chancellor announces windfall tax on energy firms
Chancellor Rishi Sunak will impose a windfall  tax on energy firms alongside a package to help households with the  cost-of-living crisis.
Mr Sunak said a 'temporary, timely, and  targeted' 25% Energy Profits Levy would be introduced for oil and gas  companies, reflecting their extraordinary profits.
The levy is expected to raise £5 billion  for the Exchequer and the legislation will include a sunset clause to ensure it  is temporary.
As an incentive for energy companies to  invest, the new levy will include a new 80% investment allowance.
The Chancellor also announced a £15  billion package of support for households.
Eight million of most vulnerable  households across the UK will receive a new one-off £650 cost of living  payment. There will also be separate one-off payments of £300 to pensioner  households and £150 to individuals receiving disability benefits
The October discount on energy bills will  be doubled to £400 and the requirement to repay it over five years has been  scrapped.
Mr Sunak said:
'We  know that people are facing challenges with the cost of living and that is why  today I'm stepping in with further support to help with rising energy  bills.  
'We  have a collective responsibility to help those who are paying the highest price  for the high inflation we face. That is why I'm targeting this significant  support to millions of the most vulnerable people in our society. I said we  would stand by people and that is what this support does today.
'It  is also right that those companies making extraordinary profits on the back of  record global oil and gas prices contribute towards this. That is why I'm  introducing a temporary Energy Profits Levy to help pay for this unprecedented  support in a way that promotes investment.'
