Electricity bills have been cut. January prices are forecast
to rise sharply. Now another £1bn-plus intervention may be coming. The
help matters, but so does understanding who ultimately pays for
it.
FundingFunnel | 7 October 2026 | Great Britain household energy
Households do not particularly care which line of government
accounting makes an energy bill smaller. If less money leaves the bank
account, that matters.
From 1 October 2026, VAT on qualifying domestic electricity in Great
Britain fell from 5% to 0%. The measure runs until 31 March 2027. The
Government says it takes around £45 off the annualised Ofgem price cap
and is funded for this financial year from cancellation of the planned
Digital ID programme. GOV.UK
That is real relief. But it arrived just as wholesale energy
pressures began threatening to overwhelm it.
Ofgem’s confirmed price cap for a typical dual-fuel household paying
by Direct Debit is £1,723 a year from 1 October to 31 December 2026, up
4% from £1,663. The cap limits unit rates and standing charges rather
than the total amount a household can spend, so actual bills still
depend on energy use. Ofgem
Cornwall Insight is forecasting that the January 2027 cap could reach
£1,999 for a typical dual-fuel household. That would be £276 above
October, an increase of about 16%. It is a forecast, not an Ofgem
decision. Cornwall
Insight
Then, as this report was being written, the political story moved
again. The Guardian reported on 6 October that Chancellor John Healey
was considering a package worth more than £1bn to help lower-income and
financially vulnerable households with rising energy bills. One option
reportedly under consideration is an additional £100 on the Warm Home
Discount, taking it from £150 to £250. No final decision has been
announced. The
Guardian
We started this report by asking whether removing VAT from
electricity was enough to make a meaningful difference if energy prices
continued to rise. Before we had finished writing it, there were signs
that the Government may be asking much the same question.
What did removing VAT
actually buy?
The VAT change is simple from the household’s point of view.
Qualifying domestic electricity in Great Britain is temporarily
zero-rated, while gas continues to carry 5% VAT. Ofgem’s published
October rates reflect the change. Ofgem
VAT on qualifying domestic electricity in Great Britain is 0% from 1
October 2026 to 31 March 2027. Gas remains subject to 5% VAT.
The Government estimates that the measure costs about £850m in
2026-27 and reduces the annualised Ofgem price cap by around £45.
Updated costs are due to be set out at the Budget. GOV.UK
That creates a reasonable economic question: is using roughly £850m
of public resources to produce an average annualised reduction of around
£45 the most effective way to support households?
That is not the same as saying the VAT reduction is pointless. Its
great advantage is simplicity. There is no application process or
eligibility test, and the Government expects suppliers to pass the tax
reduction through to customers, including those on fixed tariffs. GOV.UK
But universal support spreads the available benefit very widely. If
the objective shifts from giving everyone some breathing space to
protecting households least able to absorb a sharp January increase,
targeted support starts to look economically different.
Why are
January energy costs still under pressure?
The household price-cap forecast is part of a wider energy shock.
Cornwall Insight says the expected January increase is largely driven by
the escalating Middle East conflict and disruption to gas supplies. Oil
and transport costs have also remained elevated. Cornwall
Insight
OPEC+ decided on 4 October to keep the seven participating countries’
November production targets at September levels. Brent crude remained
above $100 a barrel around the decision. OPEC
In the UK, RAC Fuel Watch reported on 2 October that average diesel
had reached 200.01p a litre, a new record. That matters beyond motorists
because haulage, delivery and business transport costs can feed into
prices elsewhere in the economy. RAC
There is also a new domestic supply risk. Unite said more than 160
Apache offshore workers had backed strike action in a dispute affecting
assets associated with the Forties and Beryl fields, warning of possible
disruption to UK fuel supplies. No strike-related supply disruption had
been confirmed when this report was prepared. Unite
Would a £250
Warm Home Discount work differently?
The Warm Home Discount for winter 2026-27 remains a one-off £150
reduction on the electricity bill of eligible households. It covers
England, Scotland and Wales, although eligibility arrangements differ.
The scheme does not operate in Northern Ireland. GOV.UK
An additional £100 would therefore be much more visible to an
eligible household than the approximately £45 annualised benefit
attributed to removing electricity VAT. But the two policies also use
different funding mechanisms.
Ofgem describes the Warm Home Discount as a £150 rebate funded
through a levy on all domestic gas and electricity customers. From 1
April 2026, the Government changed the cost-recovery mechanism so
suppliers recover Warm Home Discount costs through gas and electricity
unit rates rather than a fixed standing charge. Ofgem
That makes the funding question important. If the Chancellor
increases the rebate to £250, will the extra £100 be funded by the
Exchequer, by increasing the levy recovered through energy unit rates,
by some hybrid arrangement, or by another mechanism entirely? The
reported proposal does not yet answer that question.
Until the Budget sets out the mechanism, a possible £250 Warm Home
Discount tells us what an eligible household might receive. It does not
tell us who ultimately finances the additional £100.
Then there is the
£1.8bn Digital ID programme
The funding already announced for the VAT cut makes the latest
£1bn-plus figure particularly interesting. The Government said the
immediate VAT measure for this financial year would be funded from
cancellation of the planned £1.8bn Digital ID programme. GOV.UK
The VAT reduction is estimated to cost around £850m in 2026-27. Put
the two headline figures next to each other and a tempting calculation
appears: £1.8bn minus £850m is roughly £950m. Now ministers are
reportedly considering an energy-support package worth more than
£1bn.
The similarity is striking. It is not proof.
There is no
confirmed £950m pot sitting there
The Government said the Digital ID programme was expected to cost
£1.8bn over the next three years. That means the £1.8bn figure is not
the same thing as £1.8bn of cash available in 2026-27. GOV.UK
The July announcement also said the savings required to fund Digital
ID were due to be identified from existing budgets through
reprioritisation, and that those savings would now be redirected towards
the VAT measure. The Government also said any further action, including
funding for longer-term measures, would be decided at the Budget
alongside an OBR forecast. GOV.UK
That leaves important questions unanswered. How much Digital ID
spending had been scheduled for 2026-27? How much was expected in later
years? Does the £850m VAT measure use only savings available this year,
or does it depend on savings originally expected over a longer period?
If another £1bn is committed to energy support, will any of it come from
the same cancelled programme, or from somewhere else?
Those are questions, not conclusions. The published information does
not yet provide the answers.
The January problem
is much bigger than £45
Cornwall Insight’s £1,999 forecast would put the annualised January
cap £276 above the confirmed October level. The Government’s £45 VAT
intervention therefore does not need to be worthless to be overwhelmed
by market events. Cornwall
Insight
Both things can be true. Removing VAT can provide genuine help, and a
subsequent rise in wholesale prices can make that help look very
small.
That is why the reported discussion of a further £1bn-plus package
matters. The policy debate may be moving from universal tax relief
towards more concentrated support for eligible households. If that
happens, the Budget will let us compare two very different ways of
spending money on the same underlying problem.
Moving a cost is
not the same as removing it
A lower energy bill can be funded in several ways. The mechanism
determines where the underlying cost ultimately lands.
The Government has several ways of making an energy bill lower. It
can reduce tax, use public spending, move policy costs into general
taxation, redistribute costs through energy suppliers, cut another
programme and redirect the planned expenditure, raise other revenue, or
borrow.
For the household opening the bill, those mechanisms may initially
look identical: the amount due is lower. Economically, they are very
different.
This is why the debate about energy affordability should not stop at
the size of the next rebate. A £100 discount recovered through energy
unit rates is not economically identical to a £100 payment funded from
general taxation. A £45 VAT saving funded through cancelling another
programme is not a free £45. A £1bn intervention financed through lower
spending elsewhere is different from £1bn of additional borrowing.
None of those funding routes is automatically right or wrong. They
simply have different consequences. Those consequences matter if we want
to understand whether a policy has reduced a cost, redistributed it or
postponed it.
So, thanks, Gov?
For households struggling to keep up with energy costs, help is help.
The temporary removal of VAT from electricity reduces bills from where
they otherwise would have been. An increase in the Warm Home Discount,
if confirmed, could provide a substantially larger reduction for
eligible households.
That should not be dismissed simply because the money has to come
from somewhere. But “where does it come from?” remains a legitimate
question.
The Government has already connected this year’s VAT reduction to
cancellation of a £1.8bn programme planned over three years. The VAT
intervention is estimated to cost around £850m this financial year. Now
a further package worth more than £1bn is reportedly being considered.
GOV.UK
Those figures do not prove that the same funding source is being used
twice. They do mean the Budget has some interesting arithmetic to
explain.
For now, we know the confirmed October price cap is £1,723. We know
Cornwall Insight is forecasting £1,999 for January. We know electricity
VAT has temporarily been removed in Great Britain. We know the existing
Warm Home Discount remains £150. And we know reporting suggests
ministers are considering substantially more support. Ofgem
The
Guardian
What we do not yet know is arguably just as important. Where will the
next £1bn come from? Will increasing the Warm Home Discount shift more
cost through the energy system or move it into government spending? How
does the three-year Digital ID cancellation fit into the financing
already announced? And when all the transfers are finished, who has
actually paid?
Those are questions for the Budget. When the answers arrive, we will
come back to the numbers.
