Fixed-rate tariffs are not affected by the price cap, so it’s worth considering if you want more price stability.
The cap is updated quarterly to reflect market changes, including wholesale energy prices.
Energy usage habits, meter types, and payment methods can significantly impact your bill, even under the cap.
Energy efficiency improvements, like better insulation and energy-saving appliances, can help reduce costs.
The UK Energy Price Cap Latest Energy Price Cap Details:
As of March 2026, the UK energy price cap is set to continue offering protection for customers on standard variable tariffs and default tariffs, and here’s what the most recent data looks like for Q1 2026:
For a typical household paying by direct debit (Standard Tariff) in March 2026:
Tariff Type Electricity Gas
Unit Rate (per kWh)
22.50p
5.45p
Standing Charge (per day)
60.15p
31.50p
Annual Price Cap (typical usage)
£1,470
£1,530
This is a moderate decrease from the previous quarter, reflecting the ongoing stabilisation of wholesale gas and electricity prices following the energy crisis in the early 2020s.
Understanding the Energy Price Cap The energy price cap is a limit set by Ofgem (the UK’s energy regulator) on the maximum price that suppliers can charge customers on standard variable or default energy tariffs, and the price cap ensures that consumers are protected from overcharging while allowing suppliers to recover reasonable operational costs.
However, the price cap does not cap your total bill; it only limits the unit rates (per kWh) and standing charges. This means that if you use more energy, your bill will still increase, even if you’re under the cap.
How the Price Cap is Determined The energy price cap is calculated by Ofgem based on:
Wholesale energy prices (which have been more stable post-2025).
Energy network costs (including distribution and transmission costs).
Supplier operating costs (for customer service, etc.).
Government obligations (such as environmental schemes and social tariffs).
A reasonable profit margin for energy suppliers.
The cap continues to be updated quarterly (in January, April, July, and October).
Who is Covered by the Price Cap? The price cap applies to those on standard variable tariffs, default tariffs, deemed tariffs, and those who are:
On prepayment meters.
Using Economy 7 or Economy 10 tariffs.
Not on fixed-term deals (fixed contracts are excluded from the cap).
How Does the Energy Price Cap Work? The cap limits two main charges on your energy bill:
1️ ⃣ Standing Charge
A fixed daily fee, regardless of usage (this covers infrastructure and admin).
2️ ⃣ Unit Rate (p/kWh)
The price you pay for each unit of electricity or gas you use.
Ofgem defines a default tariff as the standard plan a supplier puts you on after your fixed contract ends,this is often the most expensive unless capped.
Typical Usage for an Average Household To illustrate what the price cap might mean for an average household, Ofgem uses the following annual usage figures as a guide:
Gas: 12,000 kWh
Electricity: 2,900 kWh
These figures are only averages; your actual bills will depend on your specific energy consumption.
Factors Influencing Your Energy Costs Even under the price cap, several factors can affect how much you pay:
🔹 Payment method
Direct debit is often cheaperMeter type
Prepayment meters may have different ratesGeography
Prices vary by regionEnergy efficiency
Poor insulation or inefficient appliances mean higher billsUsage habits
Heating, EV charging, or running high-power equipment adds up fast

The energy price cap is a limit on the unit rates and standing charges suppliers can charge customers on standard variable and default tariffs, set by Ofgem to protect consumers from excessive charges.
2. How does the price cap work?
The price cap sets a maximum price that suppliers can charge for electricity and gas per unit, as well as a daily standing charge – it helps ensure consumers aren’t overcharged but doesn’t limit total bills, which depend on usage.
3. How often is the energy price cap updated?
The price cap is updated every three months, in January, April, July, and October, to reflect changes in wholesale energy prices and supplier operating costs.

No, it only applies to customers on standard variable, default, or deemed tariffs. Fixed-rate and other special tariffs are not subject to the cap.
5. Can I save money under the price cap?
Yes, managing your energy usage efficiently, choosing the right tariff, and paying via direct debit can help reduce costs even with the price cap in place.
6. How do payment methods affect my energy costs?
Paying by direct debit is typically cheaper than paying on receipt of a bill or using prepayment meters, which often come with higher unit rates.
7. What factors affect my energy bill, even with the price cap?
Factors such as your energy usage, the type of meter you have, your payment method, the efficiency of your appliances, and even the region you live in can all impact your energy costs.
