Energy Standing Charges and Home Batteries: What Ofgem's New Pilot Means for You

What is an energy standing charge?

Every UK electricity and gas customer pays a standing charge: a fixed daily fee just for being connected to the energy network. It covers the cost of maintaining the grid infrastructure that reaches your home, billing systems, and certain government levies. It shows up on your bill as a separate daily amount, and you pay it whether you use no energy at all or run every appliance in the house.

Under the April to June 2026 price cap, the maximum electricity standing charge is 57.2 pence per day. That is roughly £209 per year before you use a single kilowatt hour. Add gas at 29.1p per day (gas standing charges fell from April 2026 as environmental levies shifted to general taxation) and a dual-fuel household pays around £315 per year in standing charges alone.

What has Ofgem announced?

Ofgem confirmed in early 2026 a one-year pilot for lower standing charge tariffs, starting April 2026. Four suppliers are taking part: EDF, E.ON, Octopus Energy, and British Gas. Places are limited, and customers must be an eligible account holder with one of those suppliers to sign up.

The headline figure Ofgem uses is a saving of around £150 per year on standing charges for a typical dual-fuel household. That sounds straightforward, but the actual structure works like this:

• Your daily standing charge goes down significantly.
• Your per-unit electricity (and gas) rate goes up to compensate.
• Your total bill depends entirely on how much energy you consume.

Ofgem's own guidance is clear: customers on the pilot tariff who use more than average energy could end up paying more overall, not less. The pilot is designed to give low-consumption households more choice, not to cut bills across the board.

Who actually benefits from lower standing charge tariffs?

Households that tend to benefit include:

• Single-person or two-person households with modest usage
• Homes with solar panels that cover a large share of daytime consumption
• Homes with a battery that displaces a significant chunk of grid imports
• People who are away for extended periods and use very little energy

Households that are less likely to benefit include larger families with high consumption, households without any renewable generation, and anyone who uses electric heating or charges an EV heavily during peak hours.

The battery owner calculation

Here is a worked example. Ofgem's Typical Domestic Consumption Value is around 3,700 kWh/year for multi-rate customers (Economy 7 and similar) and 2,700 kWh/year for single-rate customers. A household with solar panels and a battery might draw as little as 1,000 to 1,500 kWh from the grid, because solar covers much of the daytime load and the battery absorbs any excess.

Actual pilot rates have not yet been published by any of the four participating suppliers. For illustration only, assume the lower standing charge tariff raises the electricity unit rate by 3 pence per kWh, and that the electricity portion of the £150 per year standing charge reduction is roughly £100 per year (its approximate share of the combined electricity and gas standing charges):

These are illustrative figures. The actual unit rate increase varies by supplier and will depend on how Ofgem's pilot tariff is structured when each supplier publishes their terms. The core principle holds: the less grid electricity you use, the better the lower standing charge tariff looks. Battery owners generally sit in a more favourable position than average households.

Why battery owners on Octopus Go should NOT switch

This is the most important point in this article. If you already have a home battery and you are on a time-of-use tariff like Octopus Go, switching to a lower standing charge tariff would be a significant financial mistake.

Here is why. Octopus sets Octopus Go rates across 14 regional distribution network operator (DNO) zones, so the exact numbers depend on your postcode. From April 2026, off-peak rates range from around 5p to 10p per kWh during the off-peak window (00:30 to 05:30), against a day rate of roughly 27p to 33p per kWh. Your battery charges cheaply overnight and powers your home during the expensive hours. In most regions the peak-to-off-peak spread sits between 17p and 28p per kWh, and that spread is where the real money is.

A lower standing charge tariff, by contrast, has no time-of-use off-peak window. It charges a single flat rate for every kWh you use regardless of the time of day. You would lose the cheap overnight charging window entirely and pay full price for every kWh your battery draws from the grid.

The numbers are not close. A time-of-use tariff delivers roughly ten times more value for a battery owner than any standing charge restructuring. If you have a battery and you are not yet on Octopus Go or a similar time-of-use tariff, that is the first thing to fix.

What if you have a battery but are still on a standard tariff?

Some battery owners, particularly those who have recently installed a system and have not yet switched tariffs, are on standard variable rates. If that is you, the lower standing charge pilot could offer a modest saving in the short term. But the far bigger gain comes from switching to Octopus Go or Intelligent Go. That is where most of the annual savings come from.

In other words: if you are currently on a standard variable tariff with a battery, switching to Octopus Go will save you hundreds of pounds a year. A lower standing charge tariff might save you tens of pounds. Prioritise accordingly.

The bigger picture: how UK energy bills are being restructured

Ofgem's standing charge pilot is part of a wider programme looking at whether the current balance between fixed daily charges and per-unit rates is the right one for UK households. Ofgem's lower standing charge tariffs policy page sets out the next steps beyond the one-year pilot.

Standing charges exist to recover the fixed costs of the grid, costs that do not change much based on how much electricity you use. Critics argue that charging a flat daily rate regardless of income or usage is regressive, since it hits low-use households proportionally harder than heavy users. Supporters argue that making more costs variable encourages wasteful consumption.

For battery owners, the long-term direction of travel is broadly positive. As more of the grid's fixed costs migrate toward unit rates, the financial reward for reducing consumption through battery storage and solar increases. Every penny added to the unit rate makes load shifting more valuable.

Summary: what to do if you own or are considering a home battery

• If you have a battery on Octopus Go or Intelligent Go: do not switch to a lower standing charge tariff. Your time-of-use savings dwarf any standing charge benefit.
• If you have a battery on a standard variable tariff: check whether the lower standing charge pilot tariff from your supplier saves you money given your actual grid usage. Then, more importantly, switch to Octopus Go.
• If you are considering buying a battery: note that standing charges are a fixed overhead you cannot reduce with a battery. Factor them into your full bill picture, but they should not affect your decision significantly. The tariff you choose matters far more.
• If you are evaluating whether a home battery is worth it: use your total bill, not just your unit costs, to calculate your baseline. Standing charges come off the top regardless.
