Free electricity? The smart meter schemes paying households to use electricity

Across the UK, energy suppliers are expanding schemes that offer free electricity, cashback and discounted rates when renewable energy production is high. In some cases, you can effectively be rewarded for running appliances, charging your electric car or heating water during periods when the grid has surplus power.

It is one of the few genuinely positive developments in the energy market right now. The shift is being driven by Britain’s growing reliance on renewable energy, particularly wind power. When conditions are especially windy, the UK can generate more electricity than consumers actually need. Traditionally, the National Energy System Operator (NESO) would pay wind farms to reduce output to prevent oversupply.

Now, suppliers are increasingly trying to solve that problem by encouraging you to use the excess electricity instead. The result is a growing number of “flexibility schemes” designed to reward you for shifting when you use power.

How the schemes work

Most energy suppliers already run programmes that notify you when electricity is free or significantly cheaper for a short period. You can then use that window to charge an electric vehicle, run your washing machine, use the dishwasher or heat your water tank. The offers are usually linked to periods of high renewable generation and lower overall demand.

Other schemes work slightly differently and reward you for reducing electricity use during busy periods, helping suppliers ease pressure on the grid. In both cases, the principle is the same: if you can use electricity more flexibly, you may be able to reduce your bills.

How you can access the schemes

In most cases, you will need a smart meter with half-hourly readings enabled. You should then check whether your supplier offers agile tariffs, EV charging tariffs or flexibility reward programmes. Major suppliers including Octopus Energy, Ovo, EDF and British Gas have all launched versions of these schemes.

But you do not necessarily need to switch supplier, or even change tariff to take part. Platforms such as uSwitch now allow you to join certain flexibility programmes regardless of who currently supplies your energy. In some cases, you can connect your smart meter and receive alerts about upcoming energy-saving or cashback events while staying on your existing tariff.

That makes these schemes far more accessible than many consumers realise, particularly if you want to test the potential savings without committing to a completely new energy deal.

Are there any drawbacks?

If you want to maximise the benefits from flexibility schemes, you will usually save more if you can shift larger amounts of electricity use to cheaper periods. That means households with electric vehicles, smart plugs, home batteries or automated heating systems often see the biggest rewards because they can more easily charge devices or run appliances when electricity prices fall. However, buying that technology can be expensive, and you may not save enough immediately to justify major upgrades purely for the schemes themselves.

Most flexibility programmes also rely on smart meters and half-hourly usage data. You will usually need to agree to more detailed energy monitoring so suppliers can track when you use electricity and calculate rewards accurately. While suppliers say the data is only used to manage discounts and payments, you may still feel uncomfortable sharing more detailed information about your household energy patterns.

Some tariffs also carry more risk than traditional fixed-rate deals. Agile and tracker tariffs can offer extremely cheap electricity during periods of high renewable generation, but prices can also rise sharply when wholesale markets become volatile, particularly during periods of geopolitical tension or energy supply disruption.

That means you should understand exactly how the tariff works before moving away from the stability of a fixed-rate deal.

There is also a practical consideration, in that, flexibility schemes work best if you can adapt when you use electricity. If your household relies heavily on energy during busy evening periods or you have less flexibility around your daily routine, your savings may be smaller.

Why this still matters

Despite the drawbacks, these schemes highlight a major shift in how your energy bills may work in future. As more renewable power is added to the grid, suppliers increasingly need consumers to help balance supply and demand more efficiently. That means electricity pricing is likely to become far more dynamic, with costs changing depending on demand, weather conditions and renewable generation.

If you are willing to adapt, that could create genuine opportunities to reduce your bills at a time when many households need savings wherever they can find them, and unlike many recent stories about rising energy costs, this is one area where you may finally be able to turn market volatility to your advantage.
