    The short answer

    • On a standard variable tariff? Almost always yes — typical saving £200–£500/year
    • On a fixed deal ending in <6 months? Start comparing now
    • Recently fixed at a good rate? Stay put — no exit fee surprises
    • Always check exit fees vs annual saving before switching

    When switching IS worth it

    • You're on the price cap. Standard variable tariffs are rarely the cheapest option.
    • Your fixed deal is ending soon. If you do nothing, you'll roll onto the more expensive variable tariff.
    • You haven't switched in 12+ months. Loyalty rarely pays in UK energy.
    • You want price certainty. Fixed deals lock in your unit rates against winter increases.

    When switching is NOT worth it

    • Exit fee > annual saving. Always run the numbers first.
    • You fixed recently at a competitive rate. You're already protected.
    • You're switching to a tiny supplier with no track record. Reliability matters.
