Discover exactly how much your home gas is costing you 👇
✅ Auto-fills your latest price cap rates based on your (1) region and (2) payment method.
✅ Available for both standard variable and fixed-rate tariffs.
✅ Includes 5% VAT on final bill calculations.
Multi-tariff Functionality: Suitable for both default standard variable rate tariffs (that fluctuate with market conditions), and fixed-rate tariffs (i.e. homes that locked their gas rates until 2024).
Energy Price Cap: We use the latest Energy Price Cap figures (01 October – 31 December 2023) compiled from official sources to auto-fill your unit rate and standing charge for default standard variable rate tariffs. Remember that the UK government set a maximum price cap for electricity and gas unit rates and standing charges in response to the 2022-23 UK energy crisis, and nearly all gas suppliers are charging these rates!
VAT: We include the reduced 5% VAT charged on all home energy bill calculations where explicitly mentioned.
Customisable calculation period: Choose your calculation period to match your gas consumption reporting (in kWh), which is different for everyone depending on their meter type.
Updates: This calculator was last updated in October 2023. The Energy Price Cap figures are due a revision on December 31 2023.
Limitations: Any gas bill calculations beyond this price cap period (01 October – 31 December 2023) may suffer from reduced accuracy due to the quarterly changes in price cap rates.
We’ve built a number of calculators to assist you in estimating both home and business utility costs:
In this section, we answer some frequently asked questions regarding your typical electricity costs in the UK!
How much does gas cost in the UK?
The cost of gas in the UK is influenced by (1) your gas use, (2) your type of tariff, (3) your gas rate, standing charge, region and payment option, and (4) whether it’s a domestic or commercial property.
(1) The more kWh of gas you consume, the higher your bill. Gas heating and cooking are the most common use.
(2) Your tariff determines your (3) unit rate and standing charge.
(3) The gas rate and standing charge vary depending on where your property is and how you pay for your gas. Direct debits are the cheapest, while credit is the most expensive.
(4) Domestic properties pay 5% VAT and are protected by the energy price cap. Business properties pay variable% VAT depending on their activities and are not protected by the price cap. Businesses can get help through the Energy Bill Discount Scheme.
Here are some examples of typical UK gas costs using our calculator:
A couple residing in a domestic property in Southern Scotland might use approximately 10,000 kWh of gas annually. If the current price cap remains consistent and they’re on a standard variable rate (as most people are), their yearly bill would amount to £792.67, inclusive of 5% VAT.
the same couple, if living in a comparable flat in Liverpool and paying by credit, would expect to pay around £857.40 annually. This increase is due to the costlier credit payments and the higher rates in Merseyside.
What’s the most expensive part of a home gas bill in the UK?
Under the current price cap rates, gas consumption per unit rate is the most expensive part of any default tariff.
This assumes an average use of around 10,000 kWh of gas per year (fairly typial), irrespective of region and payment type. You can test this out on our calculator.
Other factors that affect the price are your (1) tariff, (2) gas use over the time of billing and (3) your region and payment option.
(1) If you fixed your tariff when it was cheap, you’re paying less than any current variable tariff, given the adverse gas market.
(2) The longer the billing period, the higher the total daily standing charge cost. The standing charge (pence per day) is up to six times more expensive than the unit rate (pence per kWh), but given that an average household uses around 10,000 kWh of gas every year, the usage cost is much higher. The exception would be off-grid properties or those that heat their homes with heat pumps and avoid gas heating altogether.
(3) Under a default gas tariff, the region and payment option will directly affect your unit rate and standign charge as nearly all suppliers have capped their prices to the maximum (as per the government Energy Price Cap).
