What Levelise does

Levelise is a UK-based home energy management company founded in 2017 in Oxford and operating as a subsidiary of BUUK Infrastructure since its 2023 acquisition. The company provides a hardware-plus-software platform centred on the Levelise Hub — a wall-mounted controller (current generation Hub 2, £599) that connects to residential battery storage, solar PV, heat pumps, and other low-carbon technology and runs an AI-driven optimisation engine. The platform schedules battery charge and discharge against time-of-use tariffs, weather and generation forecasts, and grid signals, and participates directly in UK flexibility and wholesale markets (Balancing Mechanism, Frequency Response, Demand Flexibility Service, DSO Flexibility, Reserve Services, Wholesale Trading, Local Constraint Market, Time-of-Use Arbitrage) as a BSC-accredited Virtual Lead Party aggregating over 5,000 residential battery assets into a Virtual Power Plant.

The optimisation engine takes a probabilistic approach to household demand forecasting, evaluating a range of possible demand outcomes and accounting for asymmetric risk between being 'short' at peak times versus 'long' during low-value periods, then coordinating dispatch across all connected flexibility markets in real time. Levelise is interoperable with major battery/inverter brands including BYD, FoxESS, Tesla, SolaX, Afore, and AlphaESS, and integrates with FlatPeak (tariff data), n3rgy (smart meter data), and Enode (asset connectivity).

Revenue comes from two streams: one-off hardware sales of the Hub (standalone £599, bundles with batteries from £3,100) and ongoing flexibility market trading revenue that is shared with connected homeowners. Distribution is B2B2C via MCS-certified installer networks and the Otovo marketplace partnership, supplemented by direct-to-consumer e-commerce through shop.levelise.com and a free consumer app on iOS and Android. The company reports over £2 million paid directly to households since 2019, with 94% of customers earning more than projected flexibility payments and an average of £490/year per household in combined savings and flexibility income.

Core offering

Levelise sells the Levelise Hub, a wall-mounted hardware controller installed alongside residential battery storage systems that runs an AI-driven optimisation platform to manage battery charge/discharge against time-of-use tariffs and solar generation. The platform aggregates connected residential batteries into a Virtual Power Plant that trades flexibility services across UK wholesale and balancing markets on behalf of homeowners, with revenue shared back to participants. Levelise acts as a BSC-accredited Virtual Lead Party, enabling direct settlement in flexibility and wholesale markets.

Product overview

Levelise offers a hardware-plus-software home energy management platform centred on the Levelise Hub (generations 1.5 and 2), a wall-mounted device that acts as the intelligent controller for residential battery storage, solar PV, and heat pumps. The Levelise App provides homeowner visibility and control, while the Levelise Calculator is a standalone open-source modelling tool for industry professionals. The platform's core differentiator is its direct participation across nine UK flexibility and wholesale markets (Balancing Mechanism, Frequency Response, Demand Flexibility Service, DSO Flexibility, Reserve, Wholesale Trading, Time-of-Use Arbitrage, Efficiency Optimisation, and Local Constraint), aggregated through Levelise's Virtual Power Plant of over 5,000 residential batteries, with the company acting as a BSC-accredited Virtual Lead Party (VLP). The Hub 1.5 (outdoor-rated) and Hub 2 (redesigned, smaller) share the same optimisation engine; both are priced at £599 and are bundled with Afore and AlphaESS batteries as optional packages.
