Should I switch to a fixed rate tariff after July 2026?

Latest Trends: Will Fixed Tariffs Be Cheaper Than the Price Cap?

Following major energy crises, fixed tariffs typically offer short-lived windows of being cheaper than the standard variable (price-capped) option—especially when suppliers compete to rebuild trust and win customers post-2026.

Track the market as the new cap is announced—early movers usually benefit most.
If wholesale prices trend downward, suppliers often introduce attractive sub-cap fixed rates.
Conversely, rising prices mean fixed deals can quickly disappear, so acting fast is crucial.

How Much Could You Save?

Switching to a competitive fixed tariff at the right moment could save a typical UK household £150–£300 a year or more compared to remaining on your provider’s default rate. Actual savings depend on:

Your region and energy use
Meter type (standard or smart meter)
