What to know before choosing.
V2L vs V2H vs V2G
V2L powers appliances. V2H supplies a home through suitable equipment. V2G can export to the electricity network through an approved vehicle, bidirectional charger, installation and energy service.
AC vs DC bidirectional charging
An AC system relies more on the vehicle's onboard conversion. A DC system performs conversion in the charger. The architecture affects hardware, compatibility and approval.
CCS vs CHAdeMO
CHAdeMO enabled many early trials. CCS is now the dominant European connector and ISO 15118-20 provides newer communications for bidirectional charging, but a compliant connector alone does not create a live service.
Can I buy V2G in Britain today?
Yes, but choices remain narrow. Octopus currently lists a V2G-enabled BYD Dolphin and V2G-enabled Zaptec Pro combination for Power Pack. Other vehicles and chargers may be trials, announcements or overseas products.

E.ON publishes four current SEG tiers
E.ON lists 17.5p/kWh Next Export Premium v3 for qualifying E.ON-installed solar or battery systems, 13p/kWh Next Export Exclusive v3 for qualifying E.ON import customers, 6p/kWh variable Next Flex Export v1, and 8.5p/kWh Next Export Business v1 for qualifying SME or commercial generators. Installation date, import-tariff, system-size, metering and fixed-term conditions differ by tier; the headline rates are not generally available to every home.
Read source: E.ON NextScottishPower publishes three SmartGen export tiers
ScottishPower lists 6p/kWh SmartGen, 12p/kWh SmartGen Premium for qualifying import customers and 15p/kWh SmartGen Premium Plus for qualifying customers whose solar panels and/or battery were installed by ScottishPower. All three rates are variable; generation, certification, half-hour metering and DNO evidence requirements still apply.
Read source: ScottishPowerGovernment launches UK-wide lower-cost battery loans
The Warm Homes Loan Scheme supports no- and low-interest finance for household clean-energy upgrades across the UK, including electrical storage battery loans of up to £15,000. Ten lenders are participating initially and installations must use MCS-certified installers. This is repayable finance, not a battery grant: rates, installer restrictions, term, fees and the total amount repayable still need comparing.
Read source: Department for Energy Security and Net ZeroGovernment sets tariff-data interoperability rules for smart devices
The government has modified the Retail Energy Code to set how electricity suppliers must share tariff pricing data in a standardised format. The change takes effect on 6 November 2026, with Phase 1a planned to go live on 18 February 2027 so energy-smart appliances can respond more consistently to price signals. This is an interoperability framework, not a new retail tariff, a live battery-control service or a compatibility approval.
Read source: Department for Energy Security and Net ZeroSo Energy resolves So EV at 7.5p/kWh
So Energy's tariff index, dedicated So EV page and FAQ now agree on 7.5p/kWh from 00:00–05:00, resolving the previous 7.5p/6.5p supplier-page conflict. The overnight rate applies to the whole home; So Energy supply, a compatible half-hourly smart meter and the account-specific daytime price still matter.
Read source: So EnergyE.ON keeps £75 Next Drive Smart connection credit live
E.ON's current page identifies Next Drive Smart V7.9 at 6.5p/kWh, while its terms keep the limited £75 account credit for eligible existing customers who had not previously connected equipment and do so in the E.ON Next Home app from 14 October to 30 November 2026. They must remain connected for the eligibility check; E.ON says the credit should be applied by 14 December.
Read source: E.ON NextGovernment consults on consumer-authorised energy data sharing
The government proposes a legislative framework requiring specified energy datasets to be made securely available to authorised services when consumers choose to share them. The consultation covers datasets, accreditation, consumer protection, governance and funding; it does not yet create a live data-access route or authorise third-party battery control.

Ofgem's consultation on objective, non-promotional information about battery storage, solar panels, EV chargers and heat pumps during smart-meter visits closed on 23 October and is awaiting a decision. Marketing without prior consent would remain prohibited under the proposal; this is not yet a final licence change.
Read source: OfgemGovernment considers V2G and V2H credits in ZEV mandate review
The Department for Transport's closed ZEV-mandate review asks whether manufacturers should receive a credit for cars and vans with meaningful UK V2G or V2H capability. Proposed criteria include UK-enabled bidirectional operation, G99 or ENA evidence, warranty support, a compatible UK charger, ISO 15118-20 and a live vehicle-charger-tariff proposition. This remains a policy proposal awaiting an outcome, not a new customer incentive or compatibility approval.
Read source: Department for TransportBritish Gas publishes four current SEG tiers
British Gas lists 12p/kWh Premium for electricity customers with systems up to 15kW, 8p Extra above 15kW, 6p VoidCare for qualifying social landlords up to 15kW and 3p Export SEG for non-supply customers, developers and larger VoidCare systems. It says eligible battery-storage export can qualify, but renewable-generation, certification, DNO and half-hourly metering rules still apply.
Read source: British GasE.ON Store & Save uses a single overnight window
E.ON Next's current terms set Store & Save's lower-priced period at 02:00–05:00. The 12-month fixed tariff requires a solar battery, half-hourly smart metering, Direct Debit and online account management, carries no exit fee and publishes no general unit rates, so the personalised quote remains decisive.
Read source: E.ON NextIntelligent Octopus Flux is again marked temporarily unavailable
Octopus's live page again says Intelligent Octopus Flux is temporarily unavailable. It also remains internally inconsistent over eligibility: one section says compatible equipment need not have been installed by Octopus, while another says the tariff is currently exclusive to Octopus solar-and-battery customers. Battery Boost therefore marks it paused and restricted pending a consistent reopening route.
Read source: Octopus EnergyE.ON opens Solar Storage Steady beta with fixed windows
E.ON Next's quote-only beta combines fixed import and export windows with automatic battery steering. It requires E.ON supply and SEG, a half-hourly smart meter and one of nine listed inverter ecosystems. E.ON does not publish general unit rates, so the personalised quote, exact model and export limits remain decisive.
Read source: E.ON NextNESO brings constraint actions into the Demand Flexibility Service
From 7 October, NESO says DFS can procure both margin and system-tagged constraint actions and the Local Constraint Market no longer procures constraint actions. Households still participate through registered providers; the change does not create a direct retail payment guarantee for an individual home battery.
Read source: NESOOfgem finds modest response to standing-charge flexibility rebates
Ofgem's two trials covered more than 43,000 British Gas and ScottishPower customers. A standing-charge rebate reduced 16:00–19:00 use modestly in only one trial, and doubling the maximum reward produced only a small extra reduction. The findings support cautious tariff design rather than a guaranteed saving or response for every household.
Read source: OfgemOctopus terms confirm landlord-linked Tenant Power
Octopus's smart-tariff terms describe a restricted proposition for homes with approved solar, a battery, import and export smart meters and a MID-approved whole-home submeter. The electricity discount is agreed with the landlord and moves with the price cap; no public unit rate or open sign-up route is stated, and Octopus controls the battery.
Read source: Octopus EnergyOfgem proposes a commitment fee for queued battery projects
Ofgem says around 90 GW of battery capacity is operational or in the reformed connections queue versus a projected 29 GW requirement by 2035. The consultation concerns larger grid-connected projects, not domestic battery registrations.
Read source: OfgemBudget extends domestic electricity VAT cut to July 2027
Budget 2026 extends the temporary 0% VAT rate on qualifying domestic electricity supplies for three more months, to 1 July 2027. The government expects the extension to reduce the April 2027 Ofgem price cap by around £50 a year. It changes the VAT component, not a supplier's underlying unit rate, standing charge or the economics of every battery tariff.
Read source: HM TreasuryOctopus publishes Charge Pack control and eligibility terms
The terms require a supported battery, compatible import and export tariff, working smart meter and battery control access. Sessions are at Octopus's discretion, and the terms restrict joining another demand-response scheme with the same asset.
Read source: Octopus EnergyOVO Charge Anytime PAYG remains at 13.33p/kWh
OVO's primary page dates its pay-as-you-go smart-charging rate at 13.33p/kWh from 1 October 2026. The figure is not the price of its separate fixed-monthly plans, and boost charging still uses the customer's standard home tariff.
Read source: OVO EnergyIntelligent Octopus Go moves to 6.5p/kWh
Octopus now advertises smart charging from 6.5p/kWh, including the six-hour 23:30–05:30 whole-home window and up to six hours of eligible managed charging. Day rates, standing charges and contract terms remain account-specific, and the live vehicle or charger compatibility check remains decisive.
Read source: Octopus EnergyBritish Gas confirms current EV Power and Hive Power+ figures
British Gas's current EV page shows EV Power at 9.5p/kWh from 00:00–05:00 and a 25% Hive Power+ discount, equivalent to 7.125p/kWh when combined. Its general energy page no longer displays the older 6.75p illustration, resolving the previous public-page inconsistency.
Read source: British GasAxle lists seven supported inverter ecosystems
Axle's beta proposition lists AlphaESS, Sigenergy, Fox ESS, GivEnergy, SolaX, Solis and SolarEdge. It advertises £1/kWh during qualifying grid-stress events and a £10 monthly minimum; actual operation still depends on a compatible battery and smart-meter connection.
Read source: Axle EnergyCharge Pack lists nine battery brands as eligible now
Octopus lists AlphaESS, EcoFlow, Enphase, FoxESS, GivEnergy, HanchuESS, Huawei, Sigenergy and SolarEdge as eligible, with Tesla, SolaX, LuxPower, Solis, GoodWe, Duracell and Hinen marked coming soon.

E.ON Next now lists six automatically compatible battery ecosystems, adding Sunsynk ECCO, Accure, Elite and 8–50kW three-phase inverters while excluding Lifelynk. Unsupported batteries may still join in self-optimise mode, where the customer manages scheduling; exact model and beta eligibility remain decisive.
