Energy bills remain one of the largest household expenses. Switching is free, takes 10 minutes, and can save hundreds. One of the quickest wins in any cost of living strategy.
When Switching Makes Sense
If you're on your supplier's standard variable tariff (SVT), you're almost certainly overpaying. When fixed deals are priced below the price cap, switching can save you money; how much depends on the deal and your usage. For October to December 2026, Ofgem's cap works out at £1,723 a year for a typical dual-fuel household, so use your own annual usage to compare fixes against your current tariff.
How to Switch: Step by Step
The process is simple.
- Find your current tariff and annual usage on your bill
- Compare on Uswitch, Compare the Market, or Energy Helpline
- Check for exit fees on your current tariff
- Select the best deal — consider price, length, and service ratings
- New supplier handles everything — no need to contact old one
- Switch takes ~5 working days with no supply interruption
Beyond Switching: Reducing Usage
See our energy bills guide for comprehensive tips. Quick wins: thermostat down 1°C (saves ~£80/year), LED bulbs, smart meters, washing at 30°C.
Smart Meters and Time-of-Use Tariffs
Time-of-use tariffs charge different rates at different times. Shift heavy tasks to off-peak hours for substantial savings. Smart meters help track usage in real-time.
Frequently Asked Questions
Will I lose supply if I switch?
No. Only the billing company changes. The switch is seamless.
Should I fix my energy tariff?
If fixed deals are below the price cap, fixing locks in savings. If rates are falling, shorter fixes may be better.
What if I'm in debt to my current supplier?
You can switch if you owe less than 28 days' worth. Larger debts need agreement first.
