Your fixed energy tariff is ending — what to do
When a fixed energy deal ends you’re moved to your supplier’s standard variable tariff, which can cost more. Here’s how to decide your next move.
A fixed energy deal ending is a decision point, not an automatic disaster — but ignoring it usually means paying more than you need to.
What happens by default
Your options at the end date
- 1Note when the fix endsYour supplier must tell you in advance. That’s your window to act without exit fees.
- 2Compare a new fixCheck what your current supplier offers and compare the wider market for your usage.
- 3Fix or floatA new fix gives price certainty; the variable tariff moves with the cap. Choose for your budget and risk appetite.
In short
When your fix ends you’re moved to the standard variable tariff by default. Note the end date, compare a new fixed deal against the variable option for your usage, and switch in the deal’s final weeks to avoid exit fees.
Frequently asked questions
What happens if I do nothing when my fix ends?
You’re moved onto your supplier’s standard variable tariff, which follows the Ofgem price cap. It’s not necessarily the cheapest option, so it’s worth comparing a new fixed deal before your fix ends.
Is a new fixed deal always cheaper?
Not always — it depends on the market when your fix ends. A fix gives price certainty; the variable tariff can rise or fall with the cap. Compare both for your usage before deciding.
Will I pay an exit fee to switch?
If you switch before a fixed deal ends you may face an exit fee, but suppliers generally can’t charge one in the last weeks of the deal. Check your tariff’s terms.
