# British Gas EV Tariff: EV Power Rates, Review, and How to Switch (2026) Published: 2026-04-24 | Updated: 2026-07-14 | Source: https://www.bestchargers.co.uk/british-gas-ev-tariff/ > British Gas EV Power offers 9p/kWh overnight with any EV or charger, plus PeakSave half-price Sundays. EV Power+ drops to 7.9p/kWh with a Hive charger. Savings: £330–£490/year. British Gas EV Power is one of the UK's most straightforward EV electricity tariffs. It offers a fixed overnight rate of 9p per kWh between midnight and 5am, works with any electric vehicle and any home charger, and comes with a Sunday afternoon half-price electricity benefit called PeakSave. ## Quick answers **What is the British Gas EV Power off-peak rate?** Standard EV Power: 9p/kWh from midnight to 5am. EV Power+ (Hive charger required): 7.9p/kWh from midnight to 5am. **Does British Gas EV Power work with all electric vehicles?** Yes. Both EV Power and EV Power+ are compatible with all EVs and plug-in hybrids. **What is PeakSave?** PeakSave is a benefit on both British Gas EV tariffs that provides half-price electricity every Sunday between 11am and 4pm. **How much does British Gas EV Power save?** British Gas estimates £330–£490 annual savings compared to the Q2 2026 Ofgem standard variable rate, based on a typical household driving approximately 7,000 miles per year. **Do I need a smart meter for British Gas EV Power?** Yes. A smart meter with half-hourly data sharing is required. Customers who install a Hive EV charger can access EV Power+, which reduces the overnight rate to 7.9p/kWh — among the lowest available for a whole-home off-peak tariff. --- ## British Gas EV Power: Key Details **Standard EV Power:** - Off-peak rate: 9p/kWh - Off-peak window: Midnight to 5am (5 hours daily) - Rate applies to: Your whole home during the off-peak window - EV compatibility: All EVs and charger brands - Smart meter required: Yes — half-hourly data sharing **EV Power+ (Hive EV Charger required):** - Off-peak rate: 7.9p/kWh - Off-peak window: Midnight to 5am (5 hours daily) - Rate applies to: Your whole home during the off-peak window - Requires: Hive EV charger installed at home **PeakSave benefit (both tariffs):** - Half-price electricity every Sunday, 11am–4pm - Applies to whole-home electricity consumption - Available automatically on both EV Power and EV Power+ *Rates are subject to change. Verify current figures directly with British Gas at britishgas.co.uk before switching.* --- ## The PeakSave Benefit: What It Means in Practice PeakSave gives you electricity at half the standard daytime rate every Sunday between 11am and 4pm. For households that shift energy-intensive tasks to Sunday afternoons — laundry, dishwashing, hoovering, slow cooking — this adds meaningful savings on top of the overnight EV charging benefit. The PeakSave window is five hours per week. If your household uses an average of 3kWh during a Sunday afternoon (equivalent to one washing cycle, one dishwasher run, and general use), and the daytime rate is approximately 26p/kWh, you save approximately 39p per Sunday — around £20 per year from PeakSave alone. Combined with overnight EV charging savings, PeakSave makes British Gas EV Power a competitive package for households that actively use the benefit. --- ## How Much Can You Save on British Gas EV Power? At 9p/kWh overnight versus the Ofgem Q2 2026 standard variable rate of 24.67p/kWh, the per-unit saving is approximately 64%. For a driver covering 7,000 miles per year in an average EV: - Annual charging requirement: approximately 2,000 kWh - Annual cost at standard rate (24.67p): approximately £493 - Annual cost at British Gas EV Power (9p): approximately £180 - Annual saving on EV charging: approximately £313 British Gas estimates annual savings of £330–£490 versus the standard variable tariff, depending on usage. At 7.9p/kWh on EV Power+, the annual EV charging cost drops to approximately £158 — a saving of approximately £335 on charging alone, before PeakSave or household appliance savings. *These figures are illustrative. Actual savings depend on current tariff rates, your vehicle, and your actual overnight usage. Verify with British Gas before switching.* --- ## British Gas EV Power vs EV Power+: Which Is Right for You? **Choose standard EV Power if:** - You already have a home charger from any brand - You want the simplest possible setup — no new hardware required - You are switching from a standard tariff and want to test EV-specific billing before upgrading **Choose EV Power+ if:** - You are installing a new home charger and are open to the Hive brand - You want the lower 7.9p/kWh overnight rate - You are willing to invest in a Hive charger for the rate reduction The cost difference between 9p and 7.9p per kWh is approximately £22 per year for a driver using 2,000 kWh overnight. Whether the Hive charger investment pays back depends on the charger cost and how long you are on the tariff. --- ## Which EVs Work with British Gas EV Power? All of them. British Gas EV Power has no restrictions on EV brand or charger brand. Every EV and plug-in hybrid registered in the UK qualifies. Unlike Octopus Intelligent Go — which requires a compatible EV or smart charger for automated scheduling — British Gas EV Power is a simple timer-based tariff. You set a charging timer on your car or charger to start at midnight and run until your target battery level is reached (completing before 5am for most daily top-ups). **EVs particularly well-suited to British Gas EV Power's 5-hour window:** The Nissan Leaf 40kWh charges fully in approximately five to six hours at 7kW — a perfect fit. The MG ZS EV (51kWh) charges fully in around seven hours, but typical daily top-ups (30–50% of battery) complete well within five hours. Any EV requiring a partial top-up rather than a full charge from empty fits comfortably within the window. For large-battery EVs (VW ID.4 at 77kWh, Tesla Model Y Long Range at 75kWh) that need a more complete overnight charge, EDF GoElectric's seven-hour window may be more appropriate. --- ## Setting Up Overnight Charging on British Gas EV Power No smart charger integration is required. You set a charging timer on your vehicle or charger once, and overnight charging runs at 9p/kWh every night. **Via your car's app:** Set a departure time (e.g. 7:30am) or a charge start time (midnight). The car runs within the off-peak window automatically. **Via your charger's app:** Any smart charger allows schedule setting. Set the charge window to midnight–5am. For EV Power+ users with a Hive EV charger: the Hive app provides additional scheduling controls and usage monitoring. --- ## How to Switch to British Gas EV Power 1.

Complete the online sign-up. British Gas handles the transfer from your current supplier. 4. Switching takes approximately five working days. 5. Once live, set a midnight-to-5am charging timer on your car or charger. --- ## Comparing British Gas EV Power to Other EV Tariffs | Tariff | Off-peak rate | Window | All EVs? | PeakSave/extras? | |---|---|---|---|---| | British Gas EV Power | 9p/kWh | Midnight–5am (5h) | Yes | Sunday half-price | | British Gas EV Power+ | 7.9p/kWh | Midnight–5am (5h) | Via Hive charger | Sunday half-price | | Octopus Intelligent Go | 8p/kWh | 11:30pm–5:30am (6h) | Partial | None | | E.ON Next Drive Smart | 8p/kWh | Midnight–6am (6h) | Yes | None | | EDF GoElectric | 6.99p/kWh | 11pm–6am (7h) | Yes | None | British Gas EV Power has the shortest overnight window (5 hours) and one of the higher standard rates (9p/kWh). It compensates with universal compatibility, an established brand, and the PeakSave Sunday benefit that no other major EV tariff currently matches. EV Power+ at 7.9p/kWh is genuinely competitive — below Octopus and E.ON's 8p/kWh — but requires the Hive charger.
