About TEM Energy
TEM Energy describes itself as the UK's first "neo-utility" — a new breed of energy company that uses AI technology to connect businesses directly to renewable generators, bypassing the traditional wholesale energy market entirely.
Founded in 2021 and based at the iconic Battersea Power Station in London, TEM has attracted significant backing including a £13 million Series A funding round led by Atomico. Their client roster includes high-profile names like Silverstone Circuit.
"We're building the energy system of the future — one where businesses can access clean, traceable power directly from the source."
TEM's core product is called RED (Renewable Energy Direct). Unlike traditional suppliers who buy energy on the wholesale market, TEM connects your business directly to specific wind farms, solar installations, and hydro generators. This means you know exactly where your electricity comes from — not just a REGO certificate.
It's worth noting that TEM operates as a platform rather than a licensed supplier. They partner with P3P Partners (a licensed utility) to handle the regulatory side, while TEM provides the technology and generator relationships. They currently offer electricity only — no gas.

- 100% traceable renewable electricity

Wind Power
Energy SourceConnect directly to UK wind farms. Wind is the UK's largest renewable source, providing reliable power with strong overnight and winter generation.
- UK's most abundant renewable source
- Strong winter generation
- Traceable to specific wind farms
Solar Power
Energy SourceSource your electricity from UK solar installations. Ideal if your business operates primarily during daylight hours when solar output peaks.
- Peak generation during business hours
- Growing UK solar capacity
- Traceable to specific solar farms
Hydro Power
Energy SourceConnect to UK hydroelectric generators. Hydro provides the most consistent renewable output, less affected by weather variability than wind or solar.
- Most consistent renewable source
- Less weather-dependent
- Established UK infrastructure
Blended Portfolio
Mixed SourcesA mix of wind, solar and hydro sources optimised by TEM's AI. Balances generation patterns for more consistent supply throughout the day and year.
- Diversified renewable mix

- Balanced seasonal output
Contract Lengths
TEM typically offers 1 to 3 year contracts. Longer terms can mean better rates as generators can plan further ahead.
Electricity only — TEM does not currently supply gas. We'll confirm available sources when you request a quote.
Is TEM Right for Your Business?
An honest look at who they're best suited for — and when you might want to compare alternatives.
Good fit if...
- You have a half-hourly (HH) electricity meter — this is essential for TEM
- Sustainability is a genuine priority and you want traceable green energy, not just REGOs
- You're comfortable with a newer, tech-led approach to energy procurement
- You want to know exactly which renewable generators power your business
- You're open to longer contract terms (2-3 years) for better rates
- Your business only needs electricity — you have gas sorted elsewhere
Compare alternatives if...
- You don't have a half-hourly meter — TEM can't supply you
- You need gas as well as electricity from one supplier
- You prefer established Big Six suppliers with long track records
- You want the security of dealing with a fully licensed supplier directly
- You need very short contract terms or maximum flexibility
- You're a smaller business on non-half-hourly (NHH) metering
Not sure if you have HH metering? Check your bill or ask us — we'll confirm and find your best options.

A genuinely different approach to renewable business energy
TEM offers something most suppliers don't: actual traceability to the renewable generators powering your business — not just REGO certificates. Their AI-powered RED platform matches you directly with UK wind, solar and hydro generators, with competitive fixed pricing and transparent cost breakdowns. The catch? You need a half-hourly meter (excludes smaller businesses), they only supply electricity, and support is digital-first with no phone number published.
✓ Strengths
- 100% traceable renewable — know your generators
- Competitive pricing — up to 25% savings claimed
- Transparent cost breakdown — no hidden fees
- Strong account management (praised in reviews)
- Real sustainability credentials for ESG reporting
✗ Limitations
- Electricity only — you'll need gas elsewhere
- Half-hourly meter required (no NHH supply)
- No phone support — digital contact only
- Newer supplier (founded 2021) — limited track record
- Small Trustpilot sample (10 reviews)
Best For
Businesses with half-hourly meters who prioritise genuine green credentials, transparent pricing, and are comfortable with digital-first support. Particularly suited to companies with ESG reporting requirements.
Frequently Asked Questions
Common questions about TEM Energy
TEM operates as a technology platform that connects businesses directly with renewable generators. Your actual supply is delivered through P3P Partners Ltd, who hold the necessary Ofgem licence. TEM itself (Company 13499591) is the platform and customer-facing service, founded in 2021 and headquartered at Battersea Power Station, London.
Yes, TEM only supplies businesses with half-hourly (HH) electricity meters. This is because their platform matches your consumption to renewable generators in real-time, which requires half-hourly data. If you're unsure whether you have an HH meter, check your current bill or ask your current supplier. Typically, businesses using over 100,000 kWh annually will have one.
Traditional "green" tariffs typically buy REGO certificates separately from the energy itself — you can't verify where your actual electricity comes from. TEM's RED product connects you directly to specific UK generators (wind farms, solar installations, hydro plants), so you know exactly which sites are powering your business. This provides genuine traceability for ESG reporting, not just certificate matching.
No, TEM only supplies electricity. Their model is built around connecting businesses with renewable electricity generators, so gas isn't part of their offering. If you need both fuels, you'll need a separate gas supplier — we can help you find competitive gas rates alongside a TEM electricity contract.
TEM typically offers fixed contracts of 1, 2, or 3 years. The pricing is fully fixed for the contract duration with no hidden fees. Their AI platform optimises your energy mix from different renewable sources, but your rate remains stable regardless of wholesale market movements.
TEM operates a digital-first support model — email (hello@tem.energy) and website live chat only. They don't publish a phone number, which some customers have noted as a limitation. However, by working with us you get a dedicated account manager at Smart Energy Company who can liaise with TEM on your behalf, so you're never left chasing digital support channels alone.
Request a quote through us and we'll check if TEM is competitive for your site. You'll need a half-hourly meter and electricity-only requirements. If TEM is a good fit, we'll handle the switching process and compare their rates against other suppliers to ensure you're getting the best deal for your specific consumption profile.
