The new product (code IOG-SMB-VAR-26-10-29) has been available since 29 October 2026 in all 14 GB regions, with no fixed term and no exit fees, according to the [Octopus Energy API](https://api.octopus.energy/v1/products/IOG-SMB-VAR-26-10-29/ "Octopus Energy API"). It is aimed at Octopus domestic customers with a smart meter and a compatible electric car or charger who would rather not lock in for 12 months. Compared with the [12-month fixed version](https://api.octopus.energy/v1/products/IOG-SMB-FIX-12M-26-10-27/ "12-month fixed version") released on 27 October, the night rate is lower at 6.5p/kWh (fixed: 7.9p/kWh) and day rates are 0.02p to 1.51p/kWh lower, depending on region. Standing charges are the same on both. ## Rates by region Direct debit monthly, including VAT. Night rate in every region: 6.5p/kWh variable, 7.9p/kWh fixed. Source: Octopus Energy API tariff endpoints, checked 29 October 2026. Differences are calculated from the rounded rates shown. ## VAT on these prices The VAT included in these prices is currently 0%. HMRC's [VAT Notice 701/19](https://www.gov.uk/guidance/vat-on-fuel-and-power-notice-70119 "VAT Notice 701/19") says a temporary zero rate applies to domestic electricity in Great Britain from 1 October 2026 to 30 June 2027, after it was extended at Budget 2026. Northern Ireland stays at 5%. ## What this means for you The choice between the variable and 12-month fixed Intelligent Octopus Go products is about price risk and exit terms, not a different off-peak window. ## Illustrative calculation This uses London rates and assumes 2,000 kWh a year at night and 2,500 kWh a year at the day rate. Your usage will differ.
