For 2026, the overnight rate on the ScottishPower EV tariff is 8.5p/kWh, compared to the average standard variable tariff rate of 11.2p/kWh under the Ofgem price cap for the same period (Ofgem price cap, Q1 2026). This 2.7p/kWh saving applies exclusively to electricity used between 10pm and 6am.
The day rate on the tariff is 28.4p/kWh, and the standing charge is 52.3p per day (ScottishPower tariff T&Cs filed with Ofgem, January 2026). All figures exclude VAT at the domestic rate of 5% unless stated. The tariff is only available to customers with a smart meter and a dedicated EV charge point (ScottishPower website, “EV Tariff 2026” terms).
Quick numbers ScottishPower EV tariff vs. standard variable tariff
| Metric | ScottishPower EV tariff (2026) | Standard variable tariff (2026 average) |
|---|---|---|
| Overnight unit rate (10pm–6am) | 8.5p/kWh | 11.2p/kWh (Ofgem price cap, Q1 2026) |
| Day unit rate (6am–10pm) | 28.4p/kWh | 24.5p/kWh (Ofgem price cap, Q1 2026) |
| Standing charge (per day) | 52.3p | 53.1p (Ofgem price cap, Q1 2026) |
| Estimated annual cost for 8,000 miles/year EV | £680 | £830 (EST “EV running costs” calculator, 2026) |
The table shows that the ScottishPower EV tariff saves roughly £150 per year for a typical EV driver covering 8,000 miles annually, compared to the standard variable tariff. However, this saving depends entirely on shifting most charging to the overnight window.
Who qualifies for the ScottishPower EV tariff in 2026
To switch to this tariff, you must have a domestic electricity supply from ScottishPower at a property with a smart meter (ScottishPower eligibility page, checked March 2026). You must also own or lease an electric vehicle and have a dedicated home charge point installed by an MCS-certified or OZEV-approved installer (MCS website).
The tariff is not available to pre-payment meter customers or those currently on Economy 7 or other time-of-use tariffs (ScottishPower tariff T&Cs). Additionally, you must provide proof of EV ownership, such as a V5C logbook, within 30 days of switching (ScottishPower customer terms).
How the overnight charging window works and what it saves
The overnight window is fixed at 10pm to 6am every day, with no flexibility to shift the hours (ScottishPower tariff schedule, Ofgem register). Charging a 60kWh battery, which provides a typical range of around 200 miles, costs £5.10 per full charge at 8.5p/kWh. By comparison, the same charge on a standard day rate of 24.5p/kWh would cost £15.90 (EST 2026 EV battery size data).
You must have a smart meter that records half-hourly usage to qualify; otherwise, you pay the day rate for all consumption (Smart Energy GB, 2026). The saving is only realised if you shift at least 60% of your EV charging to the overnight window (Ofgem analysis of time-of-use tariffs, 2026).

How to verify your installer and charge point for the tariff
Your charge point must be installed by an MCS-certified or OZEV-approved installer. You can check an installer’s certification on the MCS register at www.mcscertified.com or via TrustMark at www.trustmark.org.uk (TrustMark scheme, 2026).
The charge point itself must be a smart model that can schedule charging, such as an Ohme, Zappi, or Tesla Wall Connector (ScottishPower tariff T&Cs). If you have a non-compliant charge point, such as a basic three-pin plug, you must upgrade to a smart unit before the tariff applies (ScottishPower customer support, 2026).
The direct answer Is the ScottishPower EV tariff worth it in 2026?
Yes, for most EV owners who can shift 80% or more of their charging to overnight hours, the tariff saves £150 to £200 per year compared to a standard variable tariff (EST calculator, 2026). The saving comes from the 2.7p/kWh overnight discount, which compounds with regular use.
No, if you cannot schedule charging overnight due to work patterns or lack of off-street parking, the higher day rate of 28.4p/kWh makes the tariff more expensive than a standard variable tariff (Ofgem tariff comparison tool, 2026). The tariff is also not worth it if you drive fewer than 3,000 miles per year in an EV, as the day-rate premium outweighs the small overnight saving (EST “EV running costs” data, 2026).
The tariff locks you in for 12 months, with early exit fees of £30 per fuel (ScottishPower T&Cs). For most drivers covering typical annual mileage, the tariff is a clear financial win, provided you can reliably charge overnight.
