How to Switch from Variable to Fixed Energy Tariff (UK 2026 Guide)

Why Make the Switch to a Fixed Energy Tariff in 2026?

With energy prices set to fluctuate into 2026, more UK households are considering moving from a variable-rate tariff to a fixed deal. A variable tariff means your rates go up or down as market prices change, while a fixed tariff locks in your rate for a set period—typically 12, 18, or 24 months.

• Certainty on bills: Your unit rates won't change during the fixed term, making budgeting easier.
• Protect against price increases: Avoid shocks if wholesale prices surge again.
• Unlock exclusive deals: Fixed tariffs often come with perks like smart meters, green energy, or rewards.

What’s Changing for Home Energy Switching in 2026?

The UK energy market continues to evolve after the recent price cap changes. In 2026, Ofgem's updates to the switching process have made it even simpler, faster, and penalty-free in most cases. Plus, more suppliers are competing on fixed tariffs—giving you better choice and value than ever before.

Step-by-Step: How to Switch from Variable to Fixed Tariff

1. Find your current plan details: Check your most recent bill or energy supplier’s app to see if you’re on a standard variable tariff.
2. Compare fixed tariffs online: Use trusted home energy comparison tools like Energy Plus to see the latest fixed deals, rates, and contract terms for your area.
3. Check for exit fees: Most variable tariffs are penalty-free to leave, but double-check your terms. If you're nearing the end of your contract, notice periods usually don't apply to standard variable tariffs.
4. Choose the right fixed deal: Consider unit rates, contract length, green options, and customer reviews. Some tariffs are exclusive online offers or for direct debit customers.
5. Start your switch: Switch directly with your chosen supplier or through an Ofgem-accredited comparison site. You'll need your postcode, usage details, and a valid email address.
6. Wait for the switch to complete: The new process means your switch typically takes 2-5 working days—no engineer visit or supply interruption.
7. Submit a meter reading: Take and submit a final meter reading to your old and new supplier to ensure a smooth transition and accurate billing.
