UK commercial batteries can now earn far more than bill savings alone. Through recent market changes like P415, batteries can trade in the same flexibility markets as grid-scale assets — turning stored energy into an extra revenue stream that shortens payback and differentiates installers from competitors offering a basic install.
This whitepaper explains, in plain terms, how UK battery trading actually works and how it fits into an overall energy strategy alongside solar PV and battery optimisation.
You'll learn:
- The five main flexibility markets — Demand Flexibility Service (DFS), DNO Local Flexibility, the Wholesale Market, the Balancing Mechanism (BM) and the Local Constraint Market (LCM) — what each rewards, who runs it, and which sites they suit.
- How "stacking" revenue across markets works — allocating a battery to the highest-value opportunity in every half-hour without ever double-selling the same capacity.
- How trading sits alongside a customer's existing tariff, with worked examples of import/export economics and wholesale-linked tariffs.
- The mechanics behind the scenes: baselining and deviation volumes, metering and settlement (including half-hourly settlement and COP11 asset metering).
- The key risks to set expectations correctly — under-delivery, battery cycling and warranty, market variability, and location dependency.
- A quick checklist to gauge whether a site is suitable for trading.
The takeaway for installers: trading is an upside on top of a battery that already pays for itself on bill savings — and GridVolt handles the market complexity so you don't have to.
