About Drax Energy Solutions

Drax Energy Solutions is the B2B arm of Drax Group, the UK's largest renewable electricity generator. Operating from their headquarters in Selby, North Yorkshire — home to the iconic Drax Power Station — they supply renewable electricity to over 9,000 businesses and organisations across the UK.

What sets Drax apart is that they generate their own power. Their portfolio includes the converted Drax Power Station (now running on sustainable biomass), multiple hydroelectric schemes across Scotland, and pumped storage facilities. This means when you buy from Drax, you're getting electricity from actual renewable generation assets, not just REGOs purchased on the open market.

"Drax is best suited to larger businesses with significant electricity consumption who want verified renewable credentials and are comfortable with an electricity-only supplier."

The company focuses on industrial and commercial (I&C) customers — they sold their small business portfolio to Opus Energy in 2019 to concentrate on larger accounts. This means dedicated account management, bespoke pricing, and flexible procurement options including Corporate PPAs for the biggest consumers.

However, Drax only supplies electricity — you'll need a separate gas supplier if you require dual fuel. Their Trustpilot ratings are also poor, with complaints typically relating to billing issues and out-of-contract rates. We'll cover this honestly in the reviews section.

Products & Tariffs

Drax offers flexible electricity contracts for I&C customers — from fully fixed rates to pass-through pricing. All backed by their own renewable generation.

Electricity Only Supplier

Drax supplies electricity only — they don't offer gas contracts. If you need dual fuel, you'll require a separate gas supplier or broker arrangement.

I&C Focus

Electricity only supplier — Drax focuses on I&C and corporate customers with bespoke pricing via brokers.

Is Drax Right for Your Business?

An honest look at who Drax suits best — and when another supplier might be a better fit.

Good fit if...

  • You use 30,000+ kWh of electricity per year (Drax's minimum threshold)
  • You're an I&C or corporate customer wanting renewable credentials
  • You need verified green power for Scope 2 emissions reporting
  • You want electricity from actual UK renewable generation assets
  • You're comfortable with an electricity-only supplier (separate gas)
  • You value dedicated account management and bespoke pricing

Compare alternatives if...

  • You use under 30,000 kWh annually — Drax no longer quotes for smaller users
  • You need gas supply — Drax is electricity only, no dual fuel option
  • You're an SME wanting quick online quotes — Drax uses bespoke pricing
  • You prefer a single supplier for all your energy needs
  • Trustpilot ratings matter to you — Drax scores poorly on reviews
  • You want self-service account management without account manager contact

Our view: Drax is excellent for larger businesses prioritising genuine renewable credentials. If you use under 30,000 kWh or need gas, we can match you with suppliers better suited to your profile.

What Customers Say

1.5 out of 5 34 reviews on Trustpilot as of 19 Dec 2025
⚠️

Important context: Drax's Trustpilot reviews are overwhelmingly negative (94% 1-star), with common complaints about out-of-contract standing charges and customer service. Many reviews relate to inherited contracts or change-of-tenancy situations. As a broker, we ensure you're always on contracted rates — never exposed to deemed or out-of-contract charges. We handle all communications with Drax on your behalf.

Our Verdict

Smart Energy Partner 93.1% Renewable I&C Specialist Poor Trustpilot

The greenest major generator in Britain — but only for larger businesses who can navigate the service challenges

Drax offers genuinely exceptional green credentials — 93.1% renewable electricity from their own biomass, hydro, and pumped storage assets. For I&C customers needing verified Scope 2 reporting, Corporate PPAs, or REGO-backed renewable supply, they're hard to beat on environmental substance. The catch? Drax no longer quotes businesses using under 30,000 kWh annually, and their Trustpilot score (1.5 stars) reflects serious customer service issues — particularly around out-of-contract rates and billing disputes. They're electricity-only, so you'll need a separate gas supplier. As your broker, we handle all Drax communications, ensure you're always on contracted rates, and escalate any issues directly. For the right customer profile, Drax delivers genuine renewable credentials that many "green" suppliers can't match.

✓ Strengths

  • 93.1% renewable from own generation assets
  • UK's largest single-site renewable generator
  • REGO-backed for verified Scope 2 reporting
  • Corporate PPA options for large consumers
  • Dedicated account management for I&C
  • Just 34g CO₂/kWh vs 154g UK average

✗ Limitations

  • 30,000 kWh minimum — won't quote smaller users
  • 1.5 star Trustpilot — serious service issues
  • Electricity only — no gas supply option
  • Out-of-contract rates extremely punishing
  • No SME self-service — broker access only

Best For

I&C and corporate customers using 30,000+ kWh annually who prioritise genuine renewable credentials and Scope 2 emissions reporting. Ideal for businesses needing verified green electricity from actual UK generation assets, those considering Corporate PPAs, and organisations where ESG substance matters more than customer service convenience.

Frequently Asked Questions

Common questions about Drax Energy

Drax Group plc is the UK's largest single-site renewable power generator, operating Drax Power Station in North Yorkshire. Originally a coal-fired plant, they've converted to biomass and now generate 93.1% renewable electricity. Drax Energy Solutions is their B2B supply arm, serving Industrial & Commercial (I&C) customers with electricity from their own generation assets. They also own Haven Power and Opus Energy brands, and operate hydro and pumped storage facilities across Scotland.

Since April 2022, Drax stopped quoting for businesses using under 30,000 kWh annually. This reflects their strategic focus on I&C and corporate customers where they can offer dedicated account management, bespoke pricing, and Corporate PPAs. Smaller users don't fit their business model. If you use under 30,000 kWh, we can match you with suppliers like Opus Energy (also Drax-owned but serving SMEs), or other independents better suited to smaller consumption profiles.

Yes. Drax's fuel mix shows 93.1% renewable electricity, primarily from biomass (~70%), hydro (~15%), and pumped storage (~8%). This produces just 34g CO₂ per kWh compared to the UK average of 154g — making Drax one of the greenest suppliers available. Unlike many "green" tariffs that simply purchase REGOs, Drax's renewable credentials come from actual generation at their own facilities. All supply is REGO-backed for verified Scope 2 emissions reporting.

No. Drax is an electricity-only supplier — they don't offer gas contracts. If you need both fuels, you'll require a separate gas supplier. This isn't necessarily a disadvantage: it allows you to optimise each fuel independently. We can arrange competitive gas supply alongside your Drax electricity contract, often achieving better overall rates than dual-fuel packages from single suppliers.

Drax's out-of-contract (deemed) rates are extremely punishing — this is a consistent theme in their Trustpilot reviews. Standing charges can reach £30+ per day, and unit rates are significantly above market. If your contract ends without renewal, you'll automatically roll onto these rates. Many negative reviews relate to inherited contracts or change-of-tenancy situations where businesses ended up on deemed rates. Using a broker ensures you're always on contracted rates and never exposed to these charges.

A Corporate Power Purchase Agreement (PPA) is a long-term contract (typically 5-15 years) to buy renewable electricity directly from a generator. Drax offers Corporate PPAs for large consumers (typically 10GWh+), providing price certainty, genuine additionality for ESG reporting, and direct sourcing from their renewable assets. PPAs can be structured as physical (actual power delivery) or virtual (financial hedge). They're ideal for corporates with net-zero commitments who want renewable credentials that go beyond standard REGO-backed supply.

Drax has a 1.5-star Trustpilot rating with 94% 1-star reviews. Most complaints relate to: (1) extremely high out-of-contract standing charges (£30+/day), (2) inherited contracts from Haven Power with no notification of the Drax takeover, (3) billing disputes and slow customer service responses, and (4) difficulty communicating directly with the company. Many issues stem from change-of-tenancy situations. As your broker, we mitigate these risks by ensuring contracted rates, handling all communications, and escalating issues directly.

Request a quote through Smart Energy and we'll include Drax in your comparison — provided you meet their 30,000 kWh minimum threshold. We'll need your current bill or MPAN, annual consumption, and contract end date. Drax uses bespoke pricing (no instant online quotes), so we benchmark their rates against 28+ other suppliers to ensure you're getting competitive terms. We handle all communications and paperwork, making the process seamless.
