What are the maximum standing charges in London?
Your standing charge is a daily fee you must pay to your energy supplier regardless of your energy usage. Under the rules of the Ofgem price cap, a company is allowed to charge a maximum amount, which varies depending on where you live.
London falls under the South area, meaning standing charges are currently capped at 34.55p per day for gas and 45.7p per day for electricity. This means that whoever your supplier is, these are the maximum amounts they can charge you.
Combined, this gives a maximum standing charge for gas and electricity of 80.25p.
This means that London is in the area ranked 1st out of the 14 regions in terms of maximum standing charge rates (14th is highest). The capped price is 11% lower than the average.
These rates are based on the January 2026 price cap.
What are the maximum unit prices in London?
Your unit rate is how much you are charged per unit of gas or electricity you use. These units are measured in kWh.
Similar to standing charges, a supplier can charge a maximum for each unit of gas or electricity, which varies depending on your area.
In London, as it is in the South, the cap on the unit rate for electricity is 27.83p and the maximum unit rate for gas is 6p.
Combined, this gives a maximum unit charge for gas and electricity of 114.08p.
This means that London is in the area ranked 1st out of the 14 regions in terms of maximum unit prices (1st is lowest). The capped rate is 8% lower than the average.
Again, these are based on the January 2026 price cap and will next be updated in April 2026.
