The Demand Flexibility Service - Find out more about using your energy flexibly

The Demand Flexibility Service is a voluntary scheme that encourages customers with smart meters to reduce their electricity usage at specific times. Over the last two winters, this scheme enabled homes and businesses to save enough electricity to power over 10 million homes for an hour. Millions of households and businesses participated and this page will tell you why.

What is the Demand Flexibility Service?

The Demand Flexibility Service (DFS) scheme asks people to use less electricity during busy times. This helps the National Grid manage energy better. In return, people get paid or receive other rewards.

Who started the DFS?

The DFS was developed by the National Grid, which manages the electricity system in England, Scotland, and Wales. Together with energy suppliers who have voluntarily joined the program, the option to reduce your energy for rewards was offered to consumers who had a smart meter.

How does the DFS work?

Notification

When the National Grid predicts a peak period (also known as an event), they notify the energy suppliers who have agreed to participate. These peak usage hours are typically from 4-7 pm but times may vary. These suppliers then inform all those who have enrolled in the scheme, asking them to reduce their electricity use during these specific times.
Rewards

If you successfully reduce your electricity usage during the designated times, your energy supplier rewards you. This can come in the form of a payment, a credit on your energy bill, or other types of rewards, depending on the terms set by your energy supplier.
Tracking

The program relies on smart meters to track electricity usage, making it easier to measure and verify how much energy has been saved during the events.

Why was the DFS introduced?

The DFS was designed to help people consume electricity in a more flexible way by rewarding them for reducing their electricity use during peak times. Having more flexibility in our electricity system is seen as important for two main reasons:

Helping when supplies are running low.

Electricity supplies can run low due to a larger demand from homes and businesses due to cold weather and longer, darker nights, combined with periods when less renewable energy can be produced.

Reducing the use of backup electricity production.

During peak hours it is sometimes necessary to use additional, fossil fuel power generators. This can be more expensive and release more carbon dioxide into the atmosphere.

What's next with the DFS?

As of August 2024, the National Grid has confirmed that there will be a review of the Demand Flexibility Service scheme and how it will be organised moving forward. More news should follow sometime in September/October 2024.

How to save electricity during a DFS event

Consumers could choose to use power-hungry appliances like tumble driers, ovens, dishwashers, and immersion heaters before or after the DFS event. Reducing electricity usage during the event, for example by using a microwave instead of an electric oven, would also help.

Modern televisions, laptop computers, and energy-efficient lightbulbs typically use much less electricity, so changing the time of day when used would have less impact.

You can find advice on saving energy in our Energy Saving Tips section.

Consumers are advised to follow safety guidance on using electrical devices in the home. For example, Electrical Safety First recommends appliances such as washing machines and dishwashers aren’t run unattended overnight.

Do you need a smart meter to take part in the Demand Flexibility Service?

Yes. In order to accurately measure energy usage in the home during a DFS event, and to create a baseline measure of the last 60 days of electricity usage, a smart meter capable of sending half-hourly readings is required. Additionally, you will need to give marketing consent so you can be contacted about DFS events.

Consumers without a smart meter can request one from their energy supplier at no extra cost below, or start the application process here.
