British Gas kWh Price – What Are You Actually Paying?

Monday, 18th August 2025

Trying to understand your energy bill from British Gas can sometimes feel like reading a foreign language. From unit rates to standing charges and tariffs, there’s a lot to unpack. This guide breaks down the British Gas kWh price in simple terms and helps you make smarter energy decisions at home or for your Small business.

What Is the Current BG Price Per kWh?

As of the latest price cap period, the BG price per kilowatt hour (kWh) is approximately 22.36p for electricity and 5.48p for gas. These figures can vary slightly based on your region, usage pattern, and specific tariff.

Understanding British Gas Cost per Unit

When we talk about the British Gas cost per unit, we’re referring to how much you're charged for each unit of electricity or gas consumed. This is one of the most important figures to understand on your energy bill.

  • Electricity unit: Measured in kWh
  • Gas unit: Also in kWh (converted from cubic metres)

In addition to this, you’ll also pay a standing charge – a fixed daily fee for connection to the grid.

How Are British Gas Tariffs Structured?

There are several BG tariffs available, depending on whether you prefer price stability or flexibility:

  • Fixed-rate tariffs: Lock in a unit rate for a set term (e.g., 12 or 24 months)
  • Variable tariffs: These change with the market and the Ofgem price cap
  • Prepayment tariffs: Pay-as-you-go plans using a top-up meter

How Does the British Gas kWh Rate Compare Nationally?

The British Gas kWh rate is broadly in line with the national price cap set by Ofgem. However, regional variations, time-of-use tariffs, and your consumption pattern can affect what you actually pay. It’s always worth checking for more tailored options or switching plans if your usage has changed.

Is the British Gas kWh Price Likely to Change?

Yes. The BG price per unit typically adjusts every three months in response to market conditions and regulator decisions. Keep an eye on Ofgem announcements and be aware of your tariff’s renewal date.

Why Is the British Gas kWh Price So Important?

This single rate plays a huge role in determining your energy bill. Even small changes in your British Gas cost per unit can add up to significant increases in your total monthly bill.
