Energy Price Cap Fall: The Smoke and Mirrors Behind Rising Standing Charges

From April 2026, the energy price cap will fall by around £117, bringing the average dual-fuel household bill down from £1,758 to £1,641.

Electricity unit rates drop from 26.69p/kWh to 24.67p/kWh.

At first glance, that sounds like clear relief for households.

But beneath the headline, the structure of the bill continues to shift.

Electricity Standing Charges Increase — Again

While unit rates fall, electricity standing charges are rising from 54.75p per day to 57.21p per day.

Standing charges are fixed daily costs. You pay them whether you use energy or not.

For low-usage households, this matters significantly.

Why Fixed Charges Matter

• They reduce the savings from cutting consumption
• They disproportionately affect single-occupancy homes
• They increase costs for energy-efficient households
• They shift more of the bill into unavoidable fees

Since the introduction of the price cap in 2019, standing charges have risen substantially.

While caps move quarterly, the long-term trend in fixed charges has been steadily upward.

Policy Reshuffling Behind the Scenes

Several policy decisions are influencing April’s movement:

• Renewables Obligation costs shifting into taxation
• Changes to the Energy Company Obligation (ECO)
• Warm Home Discount costs moving into unit rates

Wholesale prices are down.

But the architecture of billing is being rearranged.

Is This “Smoke and Mirrors”?

The cap falling is real. Households will see lower headline averages.

But when fixed costs rise while unit rates fall, the distributional impact changes.

Heavy users may benefit more. Low users may benefit less.

The average figure does not tell the whole story.

The Bigger Issue: Complexity

Every cap adjustment requires suppliers to:

• Update tariff engines
• Reconfigure standing charges
• Adjust VAT calculations
• Apply changes to millions of accounts

Modern energy billing is highly automated.

When structures change, errors can happen.

Lower prices do not automatically mean accurate billing.

The Real Takeaway

The price cap is a safety net.

But your individual bill depends on:

• Your exact tariff
• Your meter readings
• Your billing period
• Your supplier’s system configuration

As billing structures become more layered, independent verification becomes more important — not less.
