Standing Charge Savings Calculator

Standing charges are daily fixed fees that appear on your energy bill regardless of how much energy you use. Under the Ofgem price cap for 1 October to 31 December 2026 the average standing charge is 54.83p per day for electricity and 29.68p per day for gas, totalling around £308 per year before you use a single unit of energy. Standing charges are set by region, so your own figure can sit some way above or below that average.

The charge has doubled since 2020, when the combined figure was 25 to 30p a day. It funds network maintenance and transmission costs, and it also spreads the cost of supplier failures across every customer, a bill that grew heavily after Bulb collapsed in 2021. The households that feel it hardest are low-energy users, pensioners and second-home owners, because the fee takes no account of how little actually passes through the meter.

Some suppliers offer tariffs with lower or zero standing charges, compensating with slightly higher unit rates. Utilita and OVO have offered them since 2024, typically adding 2 to 3p per kWh in exchange. These tariffs benefit low-usage households such as small homes, holiday homes and properties with solar panels, and they suit anyone drawing under 1,500 kWh of electricity a year. High-usage households may pay more overall, so a typical 3-bed family home on 3,000 kWh or more, or any house on electric heating, is usually better off keeping the standing charge.

This calculator compares your current standing charge costs against tariffs offering lower or zero standing charges. By entering your actual consumption, it shows whether switching to a low-standing-charge tariff would save or cost you money. The arithmetic behind the breakeven point is simple enough to check by hand, since dividing the annual standing charge by the extra pence per unit gives the annual kWh below which the zero-charge tariff wins. A £200 standing charge against 2.5p extra per kWh breaks even at 8,000 kWh, which is why most homes still come out ahead paying the charge.

Switching supplier is the more dependable route for most people. Octopus Energy has the lowest standing charges in the UK in 2026 at about 45p a day combined, and switching incentives of £100 to £200 in cash are common. The default no-contract tariffs at the large suppliers, Centrica and EDF among them, generally sit at cap rates and are worth leaving. Energy Helpline, MoneySupermarket and the Cheap Energy Club all run comparisons, and a check every 6 months is enough. UK switching fell from 5 million a year in 2018 to 0.7 million in 2023 and has been climbing again through 2025 and 2026. Solar panels and a battery cut your imports but not the standing charge, and going off-grid altogether needs £30k to £80k of kit.

Ofgem has been reviewing the structure itself. A consultation across 2024 and 2025 explored making a zero standing charge tariff the default, prompted by the cross-subsidy argument that light users currently pay towards infrastructure used mainly by heavy ones. The proposed reform would replace the flat daily fee with progressive use-based pricing. Industry has resisted, because standing charges fund the supplier-of-last-resort regime that carried 4 million Bulb customers through 2021 without chaos. The likely outcome for 2026 is that standing charges remain, but fall by 10 to 20% by 2028.
