A major component within household energy bills is set to rise sharply from next year to help pay for efforts to maintain energy security during the transition to green power.

The industry regulator Ofgem’s draft determination on how much it will allow network operators to charge energy suppliers from 1 April 2026 to 31 March 2031 would push up network costs within household bills by £24 a year.

These charges currently account for 22% of the total bill.

The findings, which will be subject to consultation before a final determination by the end of the year, reflect demands on network operators to make power and gas networks fit for the future amid expansion in renewable and nuclear energy to meet net zero ambitions.

Ofgem says the plans it has given provisional approval for amount to a £24bn investment programme over the five-year term – a four-fold increase on current levels.

A total of 80 major projects includes upgrades to more than 2,700 miles of overhead power lines.

If rubber stamped as planned, the resulting network cost increases threaten further upwards pressure on bills from next April – a month that has now become synonymous with rising essential bills.

The watchdog revealed its plans as the 22 million British households on the energy price cap benefit from the first decline for a year.

It is coming down from an annual average £1,849 between April and June to £1,720 from July to September.

That’s on the back of easing wholesale costs seen during the spring – before the temporary surge in wholesale gas prices caused by the recent instability in the Middle East.

A new forecast released by industry specialist Cornwall Insight suggested households were on track to see a further, but slight, decline when the cap is adjusted again in October.

At the current level it is 28% lower than at the height of the energy-led cost of living crisis – but 10% higher than the same period last year.

The price cap does not limit total bills because householders still pay for the amount of energy they consume.

Ofgem is continuing to recommend consumers shop around for fixed rate deals in the market as they can offer savings compared with the price cap and shield homes from any price shocks seen within their fixed terms.

Jonathan Brearley, the regulator’s chief executive, said: ”Britain’s reliance on imported gas has left us at the mercy of volatile international gas prices which during the energy crisis would have caused bills to rise as high as £4,000 for an average household without government support.

“Even today the price cap can move up or down by hundreds of pounds with little we can do about it.

“This record investment will deliver a homegrown energy system that is better for Britain and better for customers. It will ensure the system has greater resilience against shocks from volatile gas prices we don’t control.

“These 80 projects are a long-term insurance policy against threats to Britain’s energy security and the instability of prices. By bringing online dozens of homegrown, renewable generation sites and modernising our energy system to the one we will need in the future we can boost growth and give ourselves more control over prices too.

“Doing nothing is not an option and will cost consumers more – this is critical national infrastructure. The sooner we build the network we need, and invest to strengthen our resilience, the lower the cost for bill payers will be in the future.”

The owner of the Lindsey oil refinery has crashed into insolvency, putting hundreds of jobs at risk at the energy conglomerate behind the Lincolnshire site.

Sky News has learnt that State Oil, the parent company of Prax Group, which has oilfield interests in the Shetlands and owns roughly 200 petrol stations, has been forced to call in administrators amid mounting losses at the refinery.

Oil industry sources said an announcement was expected later on Monday.

One of the sources said the Official Receiver had appointed FTI Consulting to act as special manager for the Lindsey facility, with Teneo hired as administrator for the rest of the group.

About 180 people work at State Oil Ltd, Prax Group’s parent entity, while roughly 440 more are employed at the Prax Lindsey Refinery.

The rest of the group is understood to employ hundreds more people.

Prax Group is owned by Sanjeev Kumar Soosaipillai, who also acts as its chairman and chief executive, according to its website.

The crisis at the Lindsey refinery, which is located on a 500-acre site five miles from the Humber Estuary, echoes that at Britain’s dwindling number of oil refineries.

According to the company, the site has an annual production capacity of 5.4 million tonnes, processing more than 20 different types of crude including petrol, diesel, bitumen, fuel oil and aviation fuels.

The refinery, which was bought from France’s Total in 2020, is understood to have become a growing drain on cash across the wider Prax Group, with which it has cross-guarantees.

Some of the company’s assets, including the petrol stations and oilfields, are not themselves in administration but will be the subject of insolvency practitioners’ decisions about their future ownership.

It was unclear on Monday morning whether bidders would step in to salvage some of the company’s assets, although industry executives believe there are likely to be buyers for many of its fuel retailing and oilfield assets.

Prax Group also bought its West of Shetland oil assets from Total after a deal struck last year.

In a statement issued to Sky News, Teneo said it would “urgently assess the position of the company and the wholesale operations”.

“A key priority is to establish the prospect for subsidiaries of the company that remain outside of any insolvency process, including retail operations under the Harvest Energies, Total Energies and Breeze brands in the UK and the OIL! Brand in Europe, Logistics operator Axis Logistics and Prax’s upstream business, formerly Hurricane Energy.

“There are no plans for redundancies at this stage.”

Prax Group could not be reached for comment, while FTI Consulting and the Official Receiver have all been contacted for comment.

Changes to welfare reforms, forced on the government by rebel Labour MPs, are being revealed today ahead of a crucial vote.

The original bill restricted eligibility for the personal independence payment (PIP) and cut the health-related element of universal credit (UC).

The government, which insisted welfare costs were becoming unsustainable, was forced into a U-turn after 126 Labour backbenchers signed an amendment that would have halted the bill at its first Commons hurdle.

Explainer: What are the welfare concessions?

While the amendment is expected to be withdrawn, after changes that appeased some Labour MPs, others are still unhappy and considering backing a similar amendment to be tabled today.

Here are the main changes to the UC and PIP bill:

• current PIP claimants will keep their benefits; stricter eligibility requirements will only apply to new claims from November 2026
• a review of the PIP assessment, which will have input from disabled people
• existing recipients of the health-related element of UC will have their incomes protected in real terms

Work and Pensions Secretary Liz Kendall said in a statement that the legislation now aims to deliver a “fairer, more compassionate system” ahead of the second reading and vote on Tuesday.

“We must build a welfare system that provides security for those who cannot work and the right support for those who can. Too often, disabled people feel trapped, worried that if they try to work, they could lose the support they depend on.

“That is why we are taking action to remove those barriers, support disabled people to live with dignity and independence, and open routes into employment for those who want to pursue it.

“This is about delivering a fairer, more compassionate system as part of our Plan for Change which supports people to thrive, whatever their circumstances.”

On Saturday, Sir Keir Starmer said fixing the UK’s welfare system was a “moral imperative”. The government claimed cuts to sickness and disability benefits would shave £5bn off the welfare bill and get more people into work.

The Resolution Foundation believes the concessions could cost as much as £3bn, while the Institute for Fiscal Studies warned that the changes make tax rises more likely.

Health Secretary Wes Streeting told Sky News that welfare bill changes have put Labour in a much better position ahead of tomorrow’s vote.

On Sunday Morning with Trevor Phillips, Mr Streeting said: “There were things that we didn’t get right, we’ve put right, and there’ll be a debate about future amendments and things, I’m sure, as it goes through in the usual way.”

On the same programme, shadow work and pensions secretary Helen Whately repeatedly refused to say whether the Conservatives would back the bill, but would review the proposals after the minister’s statement later.

“We have said that if there are more savings that actually bring the welfare bill down, if they’ll get more people into work, and if they commit to using the savings to avoid tax cuts in the autumn, which looks highly unlikely at the moment, then they have our support.”

The Liberal Democrats plan to vote against the bill and have called for the government to speed up access-to-work decisions to help people enter the workforce.
