Then in step 2 you'll enter your fix offer details — and that's it!
Variable tariff — your rate moves with the market. Ofgem adjusts the price cap quarterly, so bills can go up or down.
Fixed tariff — your rate is locked for a set period, typically 12–24 months. You're protected if prices rise, but you won't benefit if they fall.
This tool compares the two using your actual usage figures, so you can see the real pound difference over the fix term.
