Climate Fintech Platform
We take care of the financing so homeowners can get a smart battery with nothing to pay upfront. Installers earn on every job. VPP providers get a growing fleet. Investors get steady returns.
What We Do
Homeowners pay £55 a month with nothing upfront. Professional investors fund each battery. The grid gets the flexibility it needs. Installers get paid on every job. We manage the entire lifecycle from contract to grid dispatch.
Homeowners get a 9.5 kWh to 13.5 kWh smart battery system with 4G connectivity. No deposit, no credit card, just a simple monthly fee.
Every battery joins a Virtual Power Plant and starts earning revenue from grid flexibility services like Dynamic Containment and wholesale energy trading.
Each battery is funded by professional investors through a ring fenced structure. The homeowner carries no financial risk. Neither does the installer.
Installer portal, homeowner dashboard, VPP dispatch management and investor reporting. Everything runs through one technology layer built by us.
How It Works
The homeowner signs a 10 year subscription at £55 a month. Fully digital and FCA compliant.
An MCS certified installer supplies and fits a 9.5 to 13.5 kWh battery system with a 4G dongle.
After installation the customer signs up on the Third Grid platform and grants access for VPP enrolment and monitoring.
The battery starts dispatching to grid markets. The homeowner saves. The installer earns. The grid gets more stable.

Our Mission
We believe every home should have access to smart energy storage regardless of what the homeowner can afford upfront. Our financing model makes that possible while creating real returns for climate aligned investors.
About Third Grid
Third Grid sits at the intersection of three grid stakeholders. Homeowners who need affordable energy. Grid operators who need flexibility. And institutional investors who need climate positive returns.
We are building the UK's first residential battery securitisation platform. It turns individual home batteries into an institutional grade asset class that benefits everyone in the chain.
Climate Impact
The UK needs 30 to 50 GW of flexible capacity by 2035. At scale our fleet displaces thousands of tonnes of CO₂ each year.
