Fast answer (June 2026)

If you're on a standard variable tariff (i.e. the Ofgem default cap), a competitive 12-month fix is almost certainly cheaper across the next year — especially now the July 2026 cap has risen 13% to £1,862/yr. The cheapest sub-cap fixes are priced from around £1,536/yr for typical dual-fuel use, about £326 below the £1,862 cap.

If you're already on a fix, check whether you're in your last 49 days (exit-fee-free) or if a switch now nets more than the exit fee. We can do that maths for you on the quote page.

If you're considering Octopus Tracker, EDF Ensure or another time-of-use tariff, those can be cheaper still but carry seasonal risk — only suited to households with flexibility and tolerance for variable bills.

Tariff types explained

Fixed

Unit rate & standing charge locked for the term (typically 12 months). Best for cost certainty.

Capped variable (SVT)

Tracks Ofgem's quarterly cap. No exit fees, but moves up or down each January, April, July, October.

Fix-and-fall

Fixed price ceiling but tracks down if cap drops below. Small premium over the cheapest plain fix.

Tracker (e.g. Octopus Tracker)

Daily price linked to wholesale. Can be cheapest but exposes you to seasonal moves.

Time-of-use (Agile, Cosy, GoElectric)

Different rates by time of day. Needs SMETS2 smart meter and lifestyle flexibility.

Economy 7 / 10

Cheaper night rates for storage heaters or off-peak shifting. Higher day rates.
