MPs have been warned Rishi Sunak may need to provide more support for Brits struggling with the cost-of-living crisis as the price of basic essentials continues to increase.
Energy bills are the driving factor of squeeze with the typical bill soaring by £693 to nearly £2,000 in April after Ofgem increased the energy price cap by 54%.
After months of pressure from both within his own party and outside of it, the chancellor announced a package of broadly targeted measures late last month to help those struggling most with the crisis.
The interventions included:
£400 off energy bills for each household; as well as
£650 for households claiming benefits paid over two instalments in July and October;
£300 for all pensioner households; and
£150 for people claiming non-means tested benefits like personal independent payments (PIP).
However, head of economics at the Joseph Rowntree Foundation (JRF) Rebecca McDonald, told MPs in parliament on Wednesday that while the chancellor's support package is broadly well targeted it is likely more help will still be needed before the winter.
"The package he's already announced is going to offset most of the different costs across the next year," she said at a Treasury select committee.
"It will be hard during the winter for many families because they'll receive that second lump sum payment in October and that will need to tide them over until April.
"So it's definitely possible that there will be a need for extra support during the winter."
She also said, despite the chancellor's pledge to up-rate benefits with September's inflation in April, many Brits will struggle with rising bills in the meantime.
That could lead to people being plunged into even greater debt meaning it's "likely more help will be needed" for those most vulnerable.
"The longer there is a period of high inflation and higher costs, the more difficult [the financial stress] becomes - even if the extra costs have been offset," she said.
"So, even if this package prevents the extra costs making things worse, there'll still be an assessment later on in the year into how families are faring. Definitely, I think, during the winter there may be a call for further support and a need for that."
Her remarks came as the Organisation for Economic Co-operation and Development (OECD) warns that the UK is set to have the worst economic growth in the G20.
And in a sign of the worsening crisis domestically, petrol passed £2 a litre on Thursday — with the price of filling up the tank of the average family car hitting £100.

A Treasury spokesperson said: “We understand that people are struggling with rising prices which is why we have acted to protect the 8 million most vulnerable British families through at least £1,200 of direct payments this year with additional support for pensioners and those claiming disability benefits.
“Through our £37bn support package we are also saving the typical employee over £330 a year through a tax cut in July, allowing people on Universal Credit to keep £1,000 more of what they earn and cutting fuel duty by 5p saving a typical family £100.”
