Energy Bills Drop as UK Price Cap Takes Effect

Households on standard variable energy tariffs across England, Wales, and Scotland are set to pay less from April 1, 2024, after the regulator lowered the quarterly energy price cap.

The change reduces the annual bill for a typical dual-fuel home to £1,641, a 7% drop versus the cap in place from January to March, equivalent to a £117 annual saving.

What changed on April 1

The cap is set by Ofgem every three months and limits the maximum unit rates suppliers can charge for gas and electricity on standard variable tariffs.

For the April 1 to June 30 period, the cap sets gas at 5.74p per kilowatt-hour (kWh) and electricity at 24.67p per kWh, applying to about 19 million households.

Why bills are falling now

The reduction is mainly linked to adjustments in the way charges are calculated, including the removal of certain costs that had been included in annual bills.

That downward effect is partly offset by higher costs associated with maintaining energy network infrastructure, which pushes in the opposite direction.

Context: prices still elevated

Even with the April cut, household energy costs remain roughly one-third above levels seen before the Ukraine conflict, underscoring how far prices have reset since the earlier period.

The cap does not fix a household’s total bill in cash terms; what consumers pay still depends on usage, while the cap limits the unit prices on eligible tariffs.

Outlook: July risk and the next decision point

The near-term direction is uncertain, with forecasts pointing to a potential increase from July 1, 2024, of £332 for a typical household.

The cited driver is a rise in wholesale oil and gas prices following a US-Israeli conflict with Iran, though the cap for July to September has not yet been set.

Policy response and remaining unknowns

Ofgem is scheduled to publish the next cap level for the July–September quarter on May 27, which will determine whether the projected rise materializes.

The UK government has said it could provide support to vulnerable households if bills climb sharply, but it has not specified the scale, eligibility rules, or timing of any measures.
