About

Who is Engie UK?

Engie is one of the world's largest independent electricity producers, a French multinational formed in 2006 through the merger of Gaz de France and Suez SA. In the UK it operates solely in the business energy market, having sold its 70,000 residential customers to Octopus Energy in 2020. It supplies gas and electricity to over 30,000 business premises across England, Scotland and Wales, with a strong renewable-energy proposition for SMEs and tailored variable or fixed contracts for larger enterprises.

Registered as ENGIE Power Limited, Engie UK uses this legal name for Ofgem licence filings, B2B contracts and any formal communications. The trading name customers see on invoices is the shorter, recognisable form.

The company is headquartered in Leeds (UK head office), where it runs its commercial operations, account management and regulatory liaison with Ofgem.

Engie UK was established in 2006. A longer track record means more years operating under Ofgem rules and a wider history of business-customer relationships.

Engie UK is part of the ENGIE S.A. (France) group, which provides shared governance, financial backing and a wider pool of expertise in wholesale trading, hedging and regulatory work.

The company is regulated by Ofgem, and complaints fall under the Energy Ombudsman alternative dispute resolution scheme,but only for microbusinesses with under 10 staff and under £2m turnover. Larger I&C customers must take complaints through commercial dispute resolution.

Review

Engie UK,pros and cons

Engie UK is now a pure business-energy supplier with a credible renewable proposition, tailored contracts for larger users, and a parent group with the scale to absorb wholesale volatility. The product range (Guard / Simple / Balance) maps neatly to the standard SME, gas-only and pass-through needs. The main caveats are a thin public review base specifically on the UK B2B operation and rates that, once out of contract, drift well above market.

Strengths

  • Broad range of services for businesses of all sizes, from microbusinesses to large I&C.
  • Renewable energy options traceable through REGO or EU GoO certification.
  • Strong Trustpilot footprint: ~4.0/5 with 91% of reviews rated Excellent or Great.
  • Backed by a large French multinational with extensive trading and risk-management capacity.
  • Smart meter and AMR rollout for eligible customers, with automatic enrolment on AMR.

Watch-outs

  • Limited public review volume specifically for the UK business energy arm.
  • No live chat on the business website; online support is via form or email only.
  • Fuel mix historically higher in natural gas than the UK average, partly offset by renewable options.
  • Out-of-contract and deemed rates significantly more expensive than fixed plans.

Renewables

Engie UK green credentials

All renewable supply traceable through UK REGOs or EU Guarantees of Origin. Engie has cut investment in coal plants and reinvested in renewables; UK fuel-mix disclosure historically showed ~44% renewables vs UK average ~38%.

Common questions

Engie UK,frequently asked questions

Engie UK is regulated by Ofgem under a non-domestic supply licence. Whether it suits your business depends on your annual consumption, contract term and whether you need extra services (HHM, green certification, smart-meter rollout). Always compare delivered p/kWh including VAT and CCL before signing.

Switching takes between three weeks and two months for a business contract, longer than the domestic five-working-day rule. Engie UK will run a credit check, request your annual consumption and a recent meter reading, and arrange the transfer with your current supplier. Supply is never interrupted during the switch.

Fixed-rate 1-5 years for SMEs; fully tailored fixed or variable contracts for larger businesses

Most UK fixed-term business contracts include termination fees if you switch mid-contract. The supplier must accept your renewal notice in the final 30 to 60 days before the contract end-date (the renewal window varies by supplier and is set out in the original contract). Outside that window you are tied in unless you pay the exit charge.

You can reach Engie UK on 0800 139 3600, Mon-Thu 10am-5pm, Fri 9.30am-4.30pm. For a full breakdown of phone lines (sales, emergency, complaints, meter readings, account moves), see the Engie UK contact page.
