These are the maximum rates set by the Ofgem energy price cap for Q1 2026 (January to March 2026). They apply to customers on default or standard variable tariffs across Great Britain.
The gas unit cost of 6.24 pence per kilowatt hour represents a decrease from the previous quarter's rate of 6.76p/kWh. For a typical household using 11,500 kWh of gas per year, the unit rate alone accounts for approximately £717.60 annually.
2. What Is a "Unit" of Gas?
When suppliers refer to a "unit" of gas, they mean 1 kilowatt hour (kWh) of energy. This is the standard billing unit used across the UK energy industry.
However, your gas meter does not measure kWh directly. Gas meters measure the volume of gas that passes through them, either in cubic metres (m³) for metric meters or cubic feet (cu ft) for older imperial meters. Your supplier then converts this volume into kWh for billing purposes.
Gas Volume to kWh Conversion
1. Units consumed (m³) = End reading - Start reading
2. Multiply by volume correction factor: 1.02264
3. Multiply by calorific value: ~39.5 MJ/m³
4. Divide by 3.6 to convert MJ to kWh
For example, if you use 1 cubic metre of gas, that equates to roughly 11.19 kWh(1 × 1.02264 × 39.5 ÷ 3.6). You can use our gas units to kWh calculator to convert your meter readings into kWh.
3. The Ofgem Energy Price Cap Explained
The Ofgem energy price cap is a limit on the maximum amount that energy suppliers can charge per unit of gas and electricity for customers on default tariffs. It was introduced in January 2019 to protect consumers from being overcharged.
Key points about the price cap:
- It sets a maximum, not a fixed price — suppliers can charge less than the cap but not more
- Updated quarterly — Ofgem reviews the cap every three months (January, April, July, October)
- Applies to default/variable tariffs only — if you are on a fixed-rate deal, the cap does not apply to you
- Covers both unit rates and standing charges — both components are capped
- Based on wholesale costs — the cap reflects changes in wholesale gas prices, network costs, and supplier operating costs
The price cap figure often quoted in the media (e.g. "£1,738 per year") refers to what a typical dual-fuel household would pay annually. Your actual bill depends entirely on how much energy you use. For more detail, see the official Ofgem price cap guidance.
4. UK Gas Price History
The table below shows how the Ofgem price cap gas unit rate has changed over recent quarters. Prices have fluctuated significantly since the energy crisis of 2022.
| Period | Unit Rate (p/kWh) | Change |
|---|---|---|
| Q1 2026 (Current) | 6.24p | -7.7% |
| Q4 2025 | 6.76p | +21.6% |
| Q3 2025 | 5.56p | -5.1% |
| Q2 2025 | 5.86p | -13.3% |
| Q1 2025 | 6.76p | +23.4% |
| Q4 2024 | 5.48p | 0% |
| Q3 2024 | 5.48p | — |
As you can see, gas prices have been volatile. The unit rate has ranged from 5.48p to 6.76p/kWh over the past two years. These fluctuations are driven primarily by wholesale gas market prices, which are influenced by global supply and demand, geopolitical events, and seasonal factors.
5. Standing Charge Explained
The gas standing charge is a fixed daily fee you pay to your energy supplier regardless of whether you use any gas. Under the current Ofgem price cap, the gas standing charge is:
Per Day
31.43p
Per Month (approx.)
£9.43
Per Year (approx.)
£114.72
The standing charge covers the costs of maintaining the gas network, your meter, and your connection to the gas grid. You pay this charge even during summer months when you might not use any gas for heating.
There is ongoing debate in the UK about whether standing charges should be reduced or abolished entirely. Critics argue they disproportionately affect low-usage households and those in fuel poverty. Ofgem has been consulting on standing charge reform as part of its broader market review.
6. How Your Gas Bill Is Calculated
Your gas bill is made up of three components: the unit rate (based on how much gas you use), the standing charge (a fixed daily fee), and 5% VAT.
Gas Bill Formula
Usage cost = kWh used × unit rate (6.24p/kWh)
Standing charge = number of days × 31.43p/day
Subtotal = usage cost + standing charge
Total bill = subtotal × 1.05 (5% VAT)
Worked Example: 1,000 kWh in 30 Days
Usage cost = 1,000 kWh × 6.24p = £62.40
Standing charge = 30 days × 31.43p = £9.43
Subtotal = £62.40 + £9.43 = £71.83
VAT (5%) = £71.83 × 0.05 = £3.59
Total bill = £71.83 + £3.59 = £75.42

7. Regional Gas Price Variations
While the Ofgem price cap sets a national maximum, actual gas prices can vary slightly between regions. The UK gas network is divided into several distribution zones, and the cost of maintaining and operating the network differs in each area.
In practice, the differences are relatively small — typically within a fraction of a penny per kWh. Standing charges may also vary slightly by region, as network costs differ depending on the local gas distribution network.
Northern Ireland has a separate energy market and is not covered by the Ofgem price cap. Prices there are regulated by the Utility Regulator.
8. How to Get the Best Gas Price
Even with the price cap in place, there are steps you can take to reduce what you pay for gas:
Switch Supplier or Tariff
Use comparison sites like MoneySavingExpert to check if a fixed-rate deal beats the current price cap rate. Fixed tariffs can sometimes offer lower unit rates, especially if wholesale prices are expected to rise.
Fixed vs Variable Tariffs
Variable tariffs follow the price cap and change quarterly. Fixed tariffs lock in a rate for 12-24 months, giving you certainty but potentially costing more if the cap drops. Compare both options carefully before committing.
Improve Energy Efficiency
Reducing your gas consumption is the most reliable way to lower your bill. The Energy Saving Trust recommends loft insulation, cavity wall insulation, draught-proofing, and smart thermostat controls as cost-effective measures.
Monitor Your Usage
Submit regular meter readings to avoid estimated bills. Better yet, request a smart meter from your supplier — it sends automatic readings and lets you track usage in real time. Use our gas meter reading calculator to understand your consumption.
Check for Support Schemes
If you are struggling with energy costs, Citizens Advice can help you find grants, the Warm Home Discount, or other support schemes you may be eligible for.
9. Frequently Asked Questions
How much does a unit of gas cost in the UK?
As of Q1 2026, the Ofgem price cap sets the maximum gas unit rate at 6.24p per kWh. This applies to customers on default or standard variable tariffs. Those on fixed tariffs may pay a different rate depending on their deal. Use our gas unit cost guide for more detail.
What is the current gas price per kWh?
The current gas price under the Ofgem price cap (Q1 2026) is 6.24 pence per kilowatt hour (kWh). This is a decrease from the Q4 2025 rate of 6.76p/kWh.
Is the gas unit price going up or down?
The gas unit price decreased from 6.76p/kWh in Q4 2025 to 6.24p/kWh in Q1 2026. However, prices fluctuate quarterly based on wholesale gas costs. The next Ofgem price cap update is due in April 2026, and analysts expect prices may change again depending on wholesale market conditions.
What is the standing charge for gas?
The current gas standing charge under the Ofgem price cap is 31.43 pence per day(approximately £9.43 per month or £114.72 per year). This is a fixed daily charge you pay regardless of how much gas you actually use.
How many kWh of gas does a typical home use?
According to Ofgem, a typical UK household uses around 11,500 kWh of gas per year. This varies significantly depending on the size of your home, insulation quality, and heating habits. A small flat might use 8,000 kWh while a large detached house could use 17,000 kWh or more.
When does the Ofgem price cap change?
The Ofgem energy price cap is updated quarterly — in January, April, July, and October. Each new cap reflects changes in wholesale energy costs, network charges, and supplier operating costs. The next update takes effect in April 2026.
