Company

Building the future of fair energy

Licensed supply as infrastructure, so any trusted brand can put energy inside its product.

What TrueSource is

White-label energy supply as infrastructure

We hold the licensed, regulated supply capability (settlement, balancing, billing, compliance, risk, customer operations) and expose it through one API, so that a company with a product that needs energy inside it (a heat pump lease, an EV bundle, a community energy scheme, a consumer brand) can put a tariff on the meter in weeks, under its own brand, and keep the customer relationship and the product margin. We are the regulated last mile. Partners build the product.

What we are not

  • A consumer energy supplier competing for households.
  • A peer-to-peer trading marketplace. That is Tally Energy, our owned brand, which runs on us.
  • A software vendor licensing billing tools.
Why we exist

Purpose, mission, vision

Purpose

Energy should reach people fairly, on terms set by the product they chose, not by whichever supplier happens to hold the licence.

Mission

Be the licensed layer beneath the next generation of energy products: one integration that lets any trusted brand supply energy, in weeks, in every competitive market.

Vision

Consumers stop buying energy. They buy heat, miles and comfort from brands they already trust, and every one of those products runs on licensed supply infrastructure underneath. We are that infrastructure.

Values

How we make the hard calls

Fair is the product.

We exist to move the margin and the relationship from the licence-holder to the brand the consumer actually chose. If a decision makes us richer and the partner or consumer worse off, it is the wrong decision.

Correct at the ledger.

We run a regulated system where every kWh and every penny must balance. We choose invariants over checks, and boring reliability over clever features, because a wrong ledger is a wrong product.

The partner’s upside is the point.

Most of the economics stay with the partner by design. We measure ourselves by how many energy companies exist because of us, not by how much of their economics we capture.

Build once, everywhere.

We absorb per-market complexity so partners never see it. If a partner has to change their integration to enter a new territory, we have failed.

How it is built

Our own retail brand already runs on it

  • Tally Energy runs on TrueSource

    Our own peer-to-peer retail brand supplies customers on the same API partners integrate. Every feature reaches Tally before it reaches anyone else.

  • Licensed market access

    Through our partnership with a UK licensed supplier, on a pay-as-you-go basis.

  • A ledger that balances

    Every kWh and every penny is a double-entry transaction the database cannot get wrong. Half-hourly settlement, pass-through charges to six decimal places.

The future of fair energy

Consumers will stop buying energy. They’ll buy products with energy inside.

In ten years, consumers will buy heat, miles and comfort from brands they already trust, and each of those products will run on licensed supply infrastructure underneath. That is the layer we run today.
