Two households can use exactly the same amount of energy and still receive different bills because energy rates are not identical across Great Britain.
One of the clearest differences is the standing charge.
Ofgem publishes average national figures when it announces the price cap, but it also publishes separate unit rates and standing charges by energy region.
For 1 October to 31 December 2026, the Great Britain average Direct Debit standing charge is 54.83p per day for electricity and 29.68p per day for gas.
Your own rate can be higher or lower.
What is a standing charge?
A standing charge is a daily charge attached to an energy tariff.
It is normally payable regardless of how much energy you use that day.
This means a household that uses very little energy can still have a noticeable annual cost before consumption is added.
At the October average Direct Debit rates, the combined electricity and gas standing charge is 84.51p per day.
Annualised across 365 days, that is approximately £308.46.
Why does the amount vary by region?
Ofgem explains that regional differences can reflect factors including:
- the number of people in a region
- average energy use
- the amount of energy suppliers need to buy
- the cost of building, maintaining and improving energy networks
Energy is delivered through regional infrastructure, and those network costs are not identical everywhere.
The result is that a national average is useful for understanding the market, but it is not the exact rate for every postcode.
Your payment method also matters
Location is not the only variable.
Ofgem publishes different price-cap information according to how customers pay, including:
- Direct Debit
- standard credit
- prepayment meter
Multi-rate electricity arrangements such as Economy 7 also work differently from a simple single-rate tariff.
Always compare like with like when checking a rate.
How to find your correct energy region
Ofgem provides a postcode-based tool on its energy price-cap unit-rate page.
Enter your postcode to identify the relevant energy region, then check the rate for your payment method.
You can check your energy region and current capped rates on Ofgem directly on their official portal.
Do not rely on a static regional rate list that can become outdated when each new cap period takes effect.
Why regional rates matter when estimating a bill
Suppose two households each use Ofgem's typical annual consumption of 2,500 kWh of electricity and 9,500 kWh of gas.
If their regional unit rates or standing charges differ, their annual costs will not be identical even though their usage is the same.
That is why the figures in our low, typical and high energy usage guide are based on national averages and are described as illustrations.
To see the national benchmark unit rates behind these numbers, consult our guide to UK energy unit rates from October to December 2026.
The national average is still useful
Regional variation does not make the national cap figure meaningless.
The £1,723 October figure provides a common benchmark for tracking how the default-tariff market is changing.
It can help readers understand whether the overall capped rate environment is moving up or down.
For an individual household, however, the best approach is:
- find your actual annual usage
- check your own tariff unit rates
- check your own standing charges
- confirm your payment method
- use the national headline only as a comparison point
Check again when the cap changes
Ofgem updates the cap every three months.
The rates in this article apply to the 1 October to 31 December 2026 period.
The next cap period starts on 1 January 2027, with Ofgem's announcement scheduled by 25 November 2026.
When a new cap takes effect, regional rates should be checked again rather than relying on an older figure.
