Levelling the energy market for the businesses that buy direct

Most mid-market businesses negotiate their energy on their own — one renewal letter, no market data, no leverage. We exist to change that: every renewal benchmarked against the whole market, every fee fixed and visible, every decision made informed — and made by you. The saving is the outcome. A level playing field is the point.

Our mission

Every business deserves to buy energy

Every business deserves to buy energy

like the biggest.

like the biggest.

Our mission is to put professional-grade procurement — the data, the supplier reach, the negotiating leverage — in the hands of every business that buys its own energy. Fees fixed and visible. Every decision informed. Nothing hidden in a unit rate.

Who we are

A new name, built on 27 years in the market

directOS is the direct-buyer service, powered by energyengine® — a UK energy procurement technology and services platform that has spent 27 years building the tools, data and supplier relationships the market runs on. The story in three chapters:

Chapter one

27 years

The heritage

energyengine® has worked in the UK business energy market for 27 years — over one million supply contracts processed, £3.5bn of contract spend managed, and tier-1 relationships with 27 suppliers, from the biggest names to niche specialists. That depth doesn’t come from anywhere but time in the market.

Chapter two

600+

The platform

Along the way, energyengine® became a technology business. Today its platform — live wholesale data, structured tendering, AI-driven market analysis — powers over 600 energy brokers and consultants across the UK, backed by a 55-strong support team. Professional-grade infrastructure, proven at industrial scale.

OS

Direct, squared

energyengine® has always been direct to the market. directOS takes the next step: direct to the customer as well. The same platform, data and supplier access, now available to mid-market businesses that manage their own energy. A part of the market that’s long deserved better tools.

Culture, people & ethics

What we stand for

Four principles that shape how we hire, how we price, and how we treat every business we work for.

Honesty

Say it straight — plain English, no jargon, no spin. If the honest answer is “wait,” that’s what you’ll hear, even when it isn’t the quick sale.

Fairness

A level playing field is the point. Every business gets the tools, data and leverage the biggest buyers take for granted — and the same fixed, visible fee, whoever they are.

Accountability

We do what we say, and when we get something wrong we say so and put it right. No passing the buck, no small print to hide behind.

Ambition

The market never stops moving, and neither do we. Sharper data, better tools, clearer answers — most of it driven by the people who use them.

“Buy energy like the biggest.”

That’s what we’ve spent 27 years building towards. directOS puts the data, supplier reach and negotiating leverage of the largest energy buyers in the hands of every business that buys direct — fees fixed and visible, nothing hidden in a unit rate, and every decision made by you.
