What is happening when fixed energy tariffs end
Energy is a slightly different Household Bills category because the next tariff is not always automatically worse in a simple way.
When a fixed tariff ends, households often move onto a supplier's default tariff unless they choose a new deal. Ofgem's price cap helps define that default pricing, but it can still change every quarter. The important point is that the tariff changes on a known date, whether or not the household is ready.
That makes fixed energy tariff endings a clear review point. The deal ends. The pricing basis changes. The decision needs to happen before that date.
Why fixed energy tariff endings still need reviewing
The danger with energy is false certainty.
A household may assume the current fix is still fine, or may assume that moving onto the default tariff is obviously bad. Neither is always true. The right answer depends on what the new default price looks like, what fixed tariffs are available, whether exit fees still apply, and what the household values more: price certainty or flexibility.
That is why the tariff-end date matters. It is the point where the pricing basis can change, even if the household has not looked yet.
What households should check before the tariff ends
Check the exact tariff end date
Know when the fixed rates stop and what tariff follows next.
Check the fallback tariff
Understand what happens if you do nothing and the account moves onto the supplier's default pricing.
Check the switching window
MoneySavingExpert says the last 49 days of a fix are generally the penalty-free window for switching.
Check unit rates and standing charges
Do not compare energy deals on headlines alone.
Review before the tariff changes
The point is to make the decision while the current deal is still in force.
