How Demand Flexibility Services Can Lower Your Energy Bills UK Guide
Demand Flexibility Services (DFS) can lower your energy bills by rewarding you for using less electricity at peak times, usually in the early evening.
You don’t need to change supplier or install new equipment — most schemes work with a smart meter.
What Are Demand Flexibility Services (DFS)?
Demand Flexibility Services are UK programmes that pay households to reduce or shift electricity use during peak demand periods.
They are supported by:
-
The National Grid
-
Energy suppliers
-
Third-party energy apps
DFS helps keep the grid stable when demand is high.
How DFS Works
1. You Get Notified
You receive an alert when a DFS event is coming usually between 4pm and 7pm.
2. You Use Less Electricity
During the event, you:
-
Delay using appliances
-
Turn off non-essential devices
-
Shift usage to later in the evening
Some systems do this automatically.
3. You Get Paid
If you reduce usage compared to your normal level, you earn:
-
Cash rewards
-
Bill credits
-
Energy account balance
Savings vary, but many households earn £50–£100+ per year.
What Appliances Make the Biggest Difference?
During DFS events, try to avoid:
-
Washing machines and tumble dryers
-
Dishwashers
-
EV charging
-
Electric heaters
Low-impact items like lighting usually don’t matter much.
Why DFS Can Reduce Your Bills
1. You Earn Rewards
You’re paid for reducing demand not charged.
2. You Learn Better Energy Habits
Seeing when energy is expensive helps you:
-
Shift usage naturally
-
Use electricity more efficiently
3. You Avoid Peak-Price Electricity
Peak hours are often the most expensive.
Using less at these times lowers overall costs.
Do You Need Special Equipment?
To take part in DFS, you usually need:
-
A smart electricity meter
-
An eligible energy supplier or app
You do not need:
-
Solar panels
-
Batteries
-
EVs (though they help)
Is DFS Worth It?
DFS works best if you:
-
Can be flexible with appliance use
-
Are home in the early evening
-
Have a smart meter
It’s less effective if:
-
Your electricity use is already very low
-
You can’t shift usage at peak times
DFS and Renewable Energy
DFS helps the UK:
-
Reduce strain on the grid
-
Avoid fossil-fuel “backup” power
-
Make better use of renewables
Your small changes help the system as a whole.
How to Get Started with DFS
-
Check if your energy supplier offers DFS
-
Look for National Grid-supported schemes
-
Download the supplier or partner app
-
Enable notifications
-
Take part when events occur
There’s no penalty for opting out of events.
Final Verdict
Demand Flexibility Services are one of the easiest ways to save money without spending money.
If you have a smart meter and some flexibility, DFS is worth joining.
Key Takeaway
DFS doesn’t ask you to use less energy forever
just less at the most expensive times.
