our tariff update

We've temporarily removed some fixed-rate tariffs from sale for new customers, due to global events. Existing fixed tariff customers aren’t affected.

So Green Tracker is currently our best value tariff for new and renewing customers – see more below.

All our customers will still benefit from the April 2026 rate reductions.

Save £50 off the Price Cap

  • Benefit when the price cap falls in April
  • Get the reassurance of a 12‑month contract³
  • 100% renewable electricity guaranteed

  1. The Price Cap is the maximum amount suppliers can charge for a unit of energy, set by Ofgem. It changes every three months to reflect the cost of supplying energy.
  2. So Green Tracker stays £50 below the price cap – £25 per fuel, based on typical domestic consumption values (TDVC).
  3. Early exit fees of £50 per fuel apply if a customer switches before the end of their 12-month contract.
