Looking to buy or sell energy? Check out Tally Energy, our retail brand.
Companies whose products depend on energy, from heat pump leasing and EV bundles to community energy and consumer brands, integrate one API and put their tariff on the consumer’s meter in weeks, under their own brand. They keep the customer and the margin. We handle the regulated last mile.
We run settlement, billing and the industry data flows a supplier needs, ready for half-hourly settlement.
Licensed market access and supplier-of-record obligations, handled under our arrangement with a UK licensed supplier.
Half-hourly settlement with Elexon (the Balancing and Settlement Code administrator), reconciled on a double-entry ledger.
Consumer bills under your brand, with network and policy pass-through charges itemised to six decimal places.
Ofgem (the energy regulator) licence conditions, industry code obligations and regulatory reporting.
Wholesale hedging, position management and credit collateral, so imbalance never lands on your balance sheet.
Contact centre, Ombudsman compliance and debt processes, run by us behind your brand’s front door.
Registration, switching and smart-meter data flows through the retail and smart-metering systems.
Partners launch consumer energy products in weeks instead of 12–24 months.
Ofgem’s licence assessment alone takes six months, after 6–12 months of industry code and smart-meter entry work, with a further six months of controlled market entry once it is granted.

We charge a flat platform fee per meter and a small fee per kWh. Everything else is yours.
Compare an incumbent white label, where the supplier keeps the economics and the brand gets its logo on a tariff.
Every obligation Ofgem attaches to a supply licence sits with the licensee. Partners integrate an API.
The capital target, ringfenced customer balances, hedging expectations and the financial responsibility principle all attach to the licence holder. None of them reach a partner’s balance sheet.

ERCOT (the Texas grid operator) runs a large deregulated retail market with a similar competitive supply model.
Every requirement Ofgem places on a supplier, from the capital target to ringfenced Renewables Obligation and customer credit balances to the hedging expectations, attaches to the licence holder. Partners integrate an API; none of it touches their balance sheet. In Ofgem’s own words, a white label is not a supplier.
We have licensed electricity market access through a partnership with a UK licensed supplier, on a pay-as-you-go basis. We hold the licence obligations under that arrangement, and the licensee of record is named on every consumer contract and bill.
Same legal shape, opposite economics and product. Incumbent white labels keep the margin and give the brand a logo on a tariff. We give partners an API, the product margin and the ability to design the product, and the integration carries across markets.
Billing platforms license software; the supply licence stays with the supplier that built them. We are the licensed supply layer, not a software vendor: a different product, different obligations and a different moat.
We take on partners one at a time, so the first conversation is with the people who build it.
Name the product and the energy question inside it. We come back with how it runs on TrueSource and what the tariff looks like.
One API for accounts, tariffs, meters and settlement. Your product keeps its own front door; we sit behind it.
We register the supply and carry the supplier obligations. Your customers see your brand on the tariff and on the bill.
Each new territory is our licensing problem, not a second build.
Weeks from integration to live meters, against the 12–24 months a supply licence takes.
Name the product and the energy question inside it. We will come back with how it would run on TrueSource.
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.
