UK clean flexibility: what the July 2026 update puts in view

The July 2026 update is a guide to work across the electricity system, not a substitute for checking the status of an individual measure. It builds on the 2025 Clean Flexibility Roadmap, whose stated scope covers short- and long-duration flexibility technologies and broader policies intended to grow flexibility capacity. The earlier roadmap also established a governance framework for parties to deliver their actions and take on new ones where needed. The 2026 update says it shifts attention from intermediate milestones toward longer-term outcomes for consumers and the electricity system, using a theory of change and metrics for each source of flexibility. These are useful ways to organise follow-up; they do not, by themselves, establish that any particular proposal has become a binding requirement. GOV.UK [L009] [L014] [L016] [L037]

What falls within the scope?

Consumer-led flexibility includes people voluntarily moving electricity use away from peak periods or increasing use when supply is more abundant, cheaper and cleaner. The update describes both consumer propositions and the markets in which flexibility can participate. For a developer or operator, that makes tariffs, aggregation and access to flexibility markets relevant lines of enquiry—not just the installation of a device. The text identifies working-group issues around compensation for aggregator participation, competing claims over the same asset or meter point, and supply terms that may prevent non-domestic customers from working with aggregators. It says Ofgem is leading further work on those issues; it does not say in this excerpt that they have been resolved. GOV.UK [L057] [L059] [L060] [L106]

Storage is another substantial strand. The technologies identified among projects discussed in the update include pumped-storage hydropower, long-duration lithium-ion batteries, a vanadium flow battery and compressed-air energy storage. The update also treats efficient dispatch—not simply installed capacity—as an important storage outcome. Its discussion of the projects says they remain subject to final consultation and confirmation in autumn 2026. Readers should therefore distinguish the technologies in view from a final approval or delivery guarantee for any project. GOV.UK [L345] [L360]

The scope extends beyond demand shifting and storage. The interconnection section describes import and export capability as a source of flexibility and addresses both capacity toward 2030 and a pipeline of projects beyond it. Separately, the update says the role of sustainable biomethane in power, and its regulatory and delivery route to market, still need assessment. Those passages put interconnection and a potential biomethane role on the follow-up list; they should not be read as saying the biomethane assessment is complete. GOV.UK [L393] [L467] [L468]

Who has work to do?

The update assigns different kinds of work to different bodies. Government says it will assess whether consumers receiving support for low-carbon technologies could use a flexible tariff, with an opt-out. It also says it will seek primary legislative powers, when parliamentary time allows, to enable removal of final-consumption levies for demand turn-up. That is a stated legislative intention, not evidence in this excerpt that the powers or levy change are already in force. The Government Commercial Agency is designing procurement frameworks that would give public bodies routes to flexibility-enabled energy supply, including flexible tariffs and aggregator-led models.

Ofgem is to set out immediate priority steps for adapting its regulatory frameworks to consumer-led flexibility innovation. Coordination also matters: the government says it appointed Cathy McClay Flexibility Commissioner in December 2025 to accelerate delivery across boundaries, and describes quarterly industry meetings and a consumer-led advisory group she has chaired. Elexon has published a Market Facilitator Delivery Plan intended to coordinate and align flexibility markets across Great Britain. These roles point readers toward the regulator, market facilitator and cross-sector discussions as well as government policy—not toward a single owner of every action. GOV.UK [L017] [L027] [L045]

Before acting on a roadmap item, distinguish its status: an assessment, a framework under design, proposed legislation, regulatory work and a project awaiting confirmation are different stages. Check the responsible body’s subsequent decision or instrument before treating it as an operative obligation. GOV.UK [L040] [L041] [L044] [L045] [L360]
