Find the right tariff for your household, and stop overpaying.
Honest comparisons of UK energy suppliers and tariffs. How they work, which one suits your household, and exactly how to switch when the time's right.
Find the right tariff for your setup
The best energy tariff depends on how your home actually uses energy, not just who supplies it. Choose the setup that matches yours to jump to the tariffs and guides built around it.
Fixed vs variable tariffs
For most standard homes, the choice is usually between fixing your prices or staying on a variable tariff. Smart tariffs add another layer, with some deals changing daily or half-hourly based on wholesale energy prices.
Fix your unit rates for budget certainty, or stay variable to keep your options open. This guide walks through when each one makes sense and how today's prices change the answer.
