Clarity starts here

Traditional utilities today often get their energy prices from the wholesale market, which means layers of middlemen, hidden fees, and inefficiencies baked into every bill, making up as much as 30%. At tem, we’ve taken a different path. We built RED™, our modern utility service, on top of our own pricing engine that connects businesses directly with renewable generators. By running on our own transaction infrastructure and bypassing the wholesale market entirely, we cut out unnecessary markups and offer transparent pricing that’s closer to the real cost of energy. It means better prices, deeper insights and more control, helping businesses across the UK pay less for energy and finally understand what they’re paying for.

Most suppliers claiming “100% renewable” are using REGOs, which are government certificates that allow them to offset fossil fuel use on paper. It’s a common approach, but it doesn’t tell you where your energy comes from or how much of your money actually supports clean generation. RED™ is different. You get full visibility into your energy sourcing and spend. You’ll see exactly what portion of your usage and payment supports real renewable generators in our network. Because energy flows through a shared grid, no supplier can claim the electrons you use are 100% renewable. But RED™ gives you something more valuable: a clear breakdown of the percentage of your energy tied to real, clean generators. This is more than just certificates. If your business needs REGOs for reporting or compliance, we can provide them at an additional cost. But for real transparency, better pricing, and a smarter way to power your business, RED™ is the new standard.

Don't wait until the last minute to start searching for the best deal on your next energy contract. The earlier you start, the more options you'll have and the better your chances of finding a great deal! Get in touch and we’ll help you navigate your way to better pricing.

Energy companies tend to fail for one reason: exposure to wholesale volatility and layered transaction costs they can’t control. tem is built differently. We reduce risk by rebuilding the transaction layer itself - pricing and settling energy closer to its real cost, without relying on speculative wholesale positions. That structure lowers volatility and avoids the cost shocks that catch traditional suppliers out. tem is backed by long-term investment and already supports large UK businesses and generators. The system is built to last - not to trade its way through the next cycle.

If you have a half-hourly meter and can switch supplier, you’re ready to choose tem. The process is straightforward and we’ll guide you through it.

Across tem, businesses typically see savings of around 30%, because we remove layers of transaction cost rather than trying to out-trade the market. What matters more though is how those savings hold up. tem isn’t built on wholesale speculation, so prices aren’t exposed to the same swings that caught many suppliers out in 2022. By pricing energy closer to its real cost, we aim to deliver savings that are clearer, more predictable, and less prone to shock.

We get this a lot. After years of inflated bills, it can be hard to believe there’s another way. Here’s the truth: today’s wholesale prices are tied to gas, even when your power comes from renewables. That link keeps costs higher than they need to be. tem breaks that link wherever possible. By replacing the wholesale system with a more efficient way to price and settle transactions, we’ve already saved businesses over £30m while putting more money back into the hands of renewable generators.

No. RED™ is our utility experience powered by our intelligent pricing engine. It bypasses the traditional wholesale market and helps customers save and earn with a transparent, tech-driven system. Exempt Supply is a government scheme that reduces extra charges for eligible businesses and generators. A 2024 update (known as P442) made it fairer and more accessible, so we moved fast, applying on behalf of RED™ customers to unlock even more value. We handle the full process by checking eligibility, preparing the paperwork, and liaising with the central body. If you're approved, you get extra savings or earnings on top of what RED™ already delivers. By acting quickly on P442, we made sure our customers, and not just the industry giants, could benefit. So far, we’ve unlocked hundreds of thousands of pounds in extra value across the RED™ community.
