If you’ve seen headlines about the Ofgem price cap but aren’t sure what it actually means, you’re not alone. It’s one of the most common questions UK households ask when trying to understand their energy bills.
The Ofgem price cap is designed to limit the maximum amount energy suppliers can charge customers on standard variable tariffs for each unit of gas and electricity, as well as the daily standing charge. However, it is important to understand that it does not cap your total energy bill.
In this guide, we’ll explain how the Ofgem price cap works, who it applies to and whether comparing energy suppliers could still help you save money.
What Is the Ofgem Price Cap?
The energy price cap is set by Ofgem, the UK’s independent energy regulator.
Its purpose is to protect households on default or standard variable tariffs from paying excessively high prices for their gas and electricity.
Rather than limiting your total bill, the cap limits:
- The maximum unit rate suppliers can charge.
- The maximum daily standing charge.
Your final bill will still depend on how much energy you use.
Does the Price Cap Apply to Everyone?
No.
The Ofgem price cap mainly applies to customers who are on:
- Standard Variable Tariffs (SVTs)
- Default tariffs
If you’re on a fixed energy tariff, your prices are normally agreed for the length of your contract and are not directly affected by changes to the price cap until your fixed deal ends.
How Often Does the Ofgem Price Cap Change?
Ofgem reviews and updates the price cap every three months.
The level of the cap can increase or decrease depending on factors such as:
- Wholesale energy prices
- Network costs
- Government policies
- Supplier operating costs
This means your energy prices may change throughout the year if you’re on a standard variable tariff.
Why Has My Energy Bill Increased If There’s a Price Cap?
This is one of the biggest misconceptions.
The price cap does not guarantee a maximum annual bill.
If you use more gas or electricity than the average household, your bill will naturally be higher because you’re paying for more units of energy.
Other factors can also increase bills, including:
- Higher energy usage during colder months
- Larger homes
- Poor insulation
- Rising standing charges
Reducing your energy consumption can help lower your overall costs.
Can You Still Save Money by Switching Energy Supplier?
Yes.
Even when the price cap is in place, comparing energy suppliers may still help you find a tariff that better suits your circumstances.
Depending on market conditions, you may benefit from:
- Fixed energy tariffs
- Different payment options
- Better customer service
- Renewable energy tariffs
- More competitive standing charges
Every household is different, so it’s worth reviewing your options regularly.
Fixed Tariffs vs Standard Variable Tariffs
A fixed tariff locks in your unit rates for an agreed period, providing more certainty over your energy prices.
A standard variable tariff changes whenever your supplier changes its prices, subject to the Ofgem price cap.
Choosing the right tariff depends on your personal circumstances, budget and attitude to price certainty.
Tips to Reduce Your Energy Bills
While you cannot control the price cap, there are practical steps that may help reduce your energy costs.
These include:
- Comparing energy suppliers regularly.
- Improving your home’s insulation.
- Using energy-efficient appliances.
- Turning off appliances when not in use.
- Monitoring your energy usage.
- Reviewing your tariff before it expires.
Small changes can make a noticeable difference over time.
