UK Gas Price Per M3 in 2026 — Key Figures

The cost of 1 cubic metre of gas in the UK depends on two variables: your unit rate (set by your energy tariff or the Ofgem price cap) and your regional calorific value (which determines how much energy is in each m³). At the Q1 2026 Ofgem price cap unit rate of 7.42p/kWh and UK average CV of 39.5 kWh/m³, each cubic metre costs approximately 83.2p in energy charges. Standing charge adds a further ~29p per day regardless of usage.

The Gas Price Per M3 Formula

Your energy bill does not charge you per cubic metre directly — it charges per kWh. To find your cost per m³, you must convert m³ to kWh using the calorific value, then apply your unit rate. The Ofgem volume correction factor (1.02264) accounts for the difference between gas volume at your meter conditions versus standard reference conditions.

💷 Gas Cost Per M3 Formula
Cost per m3 (pence) = unit rate (p/kWh) × CV × VCF ÷ 3.6
→ At CV 39.5: cost per m3 = unit rate × 11.213
→ At 7.42p/kWh: cost per m3 = 7.42 × 11.213 = 83.20p = £0.832/m3

How to Calculate Gas Cost — Step by Step

1

Find Your Unit Rate

Locate the gas unit rate in pence per kWh on your energy bill — usually on page 1 under "Gas charges." In Q1 2026, the Ofgem price cap sets a typical unit rate of 7.42p/kWh. Fixed tariff customers may have a different rate. Do not confuse the unit rate with the standing charge, which is a flat daily fee unrelated to consumption.

Bill example: Gas unit rate: 7.42p per kWh ← use this Standing charge: 29.0p per day ← separate charge VAT (5%): included in above figures
Some bills show the unit rate inclusive of VAT, others exclusive. This calculator assumes exclusive VAT and adds 5% at the end. Check your bill's footnotes.
2

Find Your Calorific Value

The CV is printed on your gas bill in the tariff details section, often expressed as MJ/m³. Divide by 3.6 to convert to kWh/m³. If you can't find it, use 39.5 kWh/m³ (the UK national average), which is accurate to within ±3% for most UK addresses. CV is higher in southern England and lower in Scotland and northern England.

Bill example (various formats): "Calorific value: 39.5 kWh/m³" ← ready to use "Calorific value: 142.2 MJ/m³" ← divide by 3.6 = 39.5 kWh/m³ "Energy content: 39.5" ← kWh/m³ implied
3

Calculate Cost Per M3

Apply the formula: cost per m3 (pence) = unit rate × CV × VCF ÷ 3.6. At UK average CV 39.5 and VCF 1.02264, the kWh per m³ factor = 39.5 × 1.02264 ÷ 3.6 = 11.213. Multiply your unit rate by 11.213 to get pence per m³.

At 7.42p/kWh and CV 39.5: kWh per m³ = 39.5 × 1.02264 ÷ 3.6 = 11.213 kWh/m³ Cost per m³ = 7.42 × 11.213 = 83.20p = £0.832/m³ At 6.80p/kWh (fixed tariff), CV 39.5: Cost per m³ = 6.80 × 11.213 = 76.25p = £0.763/m³
4

Add Standing Charge and VAT

Total bill = energy charge + standing charge + VAT at 5%. Standing charge = p/day × number of days. VAT at 5% applies to the whole bill including standing charge. This is the reduced rate for domestic fuel — not the standard 20% that applies to most goods and services.

Example: 50 m³ over 30 days at 7.42p/kWh: kWh used = 50 × 11.213 = 560.6 kWh Energy cost = 560.6 × 7.42p = 4,160p = £41.60 Standing ch. = 29.0p × 30 = 870p = £8.70 Subtotal = £41.60 + £8.70 = £50.30 VAT (5%) = £50.30 × 0.05 = £2.52 Total bill = £50.30 + £2.52 = £52.82

Ofgem Gas Price Cap History 2022–2026

The Ofgem price cap is updated quarterly and sets a limit on the unit rate and standing charge energy suppliers can charge customers on default tariffs. The cap does not limit the total bill — it limits the rate, so higher usage still results in a higher bill. Below is the quarterly history of gas unit rates and typical standing charges since 2022.

Gas Price Per M3 by UK Region 2026

Because calorific value varies by region, the cost per m³ differs even when the unit rate is identical. A customer in Scotland with CV 38.0 kWh/m³ pays approximately 80.5p per m³ at Q1 2026 rates, while a customer in London with CV 40.5 kWh/m³ pays approximately 85.7p — roughly 6.5% more per cubic metre, even on the same tariff. The total annual cost in kWh is the same if usage patterns are identical, but the m³ consumed will differ.

Frequently Asked Questions

How much does 1 m3 of gas cost in the UK in 2026?
At the Ofgem Q1 2026 price cap unit rate of 7.42p/kWh and UK average calorific value of 39.5 kWh/m³: 1 m³ of gas costs approximately 83.2p (£0.832) in energy charges. This excludes the standing charge (≈29p/day) and VAT (5%). Regional variations: Scotland/North at CV 38.0 → ~79.9p/m³; London/South East at CV 40.5 → ~85.1p/m³. Use the calculator above with your exact unit rate and CV for a precise result.
What is the Ofgem gas price cap unit rate in 2026?
The Ofgem Q1 2026 price cap (January–March 2026) sets a typical gas unit rate of 7.42p/kWh and standing charge of 29.0p/day for a typical direct debit dual fuel household. The Q2 2026 cap (April–June 2026) reduced to approximately 7.03p/kWh and 29.6p/day. Ofgem updates the cap every quarter — always check ofgem.gov.uk for the current quarter's exact figures. The price cap applies to standard variable and default tariffs; fixed tariffs may be different.
How do I calculate gas cost from my meter reading?
Four steps: (1) Subtract previous reading from current to get m³ used. (2) Multiply m³ × CV × VCF ÷ 3.6 to get kWh — e.g. 50 m³ × 39.5 × 1.02264 ÷ 3.6 = 560.7 kWh. (3) Multiply kWh × unit rate in p/kWh — e.g. 560.7 × 7.42p = 4,160p = £41.60. (4) Add standing charge and 5% VAT. Total for 50 m³ over 30 days at Q1 2026 rates ≈ £52.82. Use the calculator above to do all steps instantly.
Why does gas cost more per m3 in some UK regions?
The cost per m³ varies because calorific value differs by region. Southern England receives richer gas (higher CV, ~40–41 kWh/m³) meaning each m³ contains more energy and therefore costs more at the same p/kWh unit rate. Scotland and northern England receive slightly leaner gas (CV 37.5–39.0 kWh/m³). Your energy bill charges per kWh of energy — not per m³ of volume — so the total energy cost is fair, but the cost per cubic metre physically consumed will differ. This is why your bill always shows a calorific value and why our calculator includes a CV input.
What is the gas standing charge in 2026?
Under the Ofgem Q1 2026 price cap, the typical gas standing charge is approximately 29.0p per day (£8.70 per 30-day month, £105.85 per year). Q2 2026 standing charge: approximately 29.6p/day. Standing charges vary by region — some network areas pay up to 34p/day, others as low as 26p/day. The standing charge covers gas distribution network maintenance costs and is payable even if you use no gas at all. It is set by the network operator in each region, not just by your supplier.
What is VAT on gas in the UK in 2026?
Domestic gas in the UK is subject to 5% VAT (the reduced rate), not the standard 20% rate. This 5% applies to both the unit rate charges and the standing charge. Most energy bill unit rates quoted by suppliers are inclusive of 5% VAT. Business gas customers typically pay 20% VAT unless they qualify for the reduced rate (e.g. care homes, charities). The 5% reduced rate for domestic fuel has been maintained through successive Budgets and remains in place for 2026.
How much gas does a typical UK household use per year in 2026?
Ofgem's 2026 Typical Domestic Consumption Values (TDCVs) are: Low: 7,500 kWh/yr (≈670 m³), Medium: 11,500 kWh/yr (≈1,028 m³), High: 17,000 kWh/yr (≈1,519 m³). At Q1 2026 Ofgem rates, a medium-usage household pays approximately £854/year in energy charges plus £106/year standing charge = ~£960–£1,000/year total (inc. 5% VAT). Usage varies significantly by property size, insulation, occupancy and thermostat settings. Well-insulated modern homes can use 30–40% less than the medium benchmark.
How do I find the calorific value on my gas bill?
Look for "calorific value", "CV" or "energy content" in the tariff details or meter reading summary section of your gas bill — usually on page 2 or 3 in small print. It is most commonly shown in MJ/m³ (megajoules per cubic metre) — divide by 3.6 to get kWh/m³. Example: 142.2 MJ/m³ ÷ 3.6 = 39.5 kWh/m³. If your bill doesn't show it, use 39.5 kWh/m³ (UK national average) for a result accurate to within ±3% for most UK addresses.
Is it cheaper to switch energy supplier in 2026?
In 2026, fixed tariffs have returned from suppliers including Octopus Energy, EDF, British Gas and E.ON. Some fixed deals offer unit rates of 6.80–7.20p/kWh — below the Q1 2026 Ofgem cap of 7.42p/kWh, potentially saving £50–£130/year for a medium user. However, fixed tariffs carry exit fees (typically £30–£75) if you switch during the term, and lock in a rate that may become uncompetitive if the Ofgem cap falls further. Compare using Ofgem-accredited comparison sites. Use the calculator above with different unit rates to estimate your potential saving from switching.
