About

Who is E.ON Business?

E.ON Business is the small- and medium-enterprise (SME) and industrial & commercial (I&C) arm of E.ON UK, part of the German multinational E.ON SE. A member of the historic UK Big Six, E.ON is one of the largest energy suppliers in the country and supplies gas and electricity to millions of homes and businesses. The business unit offers SME fixed-rate plans of one to three years with 100% renewable electricity as standard, alongside tailored contracts for large I&C accounts.

Registered as E.ON Next Energy Limited (E.ON UK plc / E.ON SE group), E.ON Business 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 Coventry (UK head office); Essen, Germany (group HQ), where it runs its commercial operations, account management and regulatory liaison with Ofgem.

E.ON Business was established in 2000. A longer track record means more years operating under Ofgem rules and a wider history of business-customer relationships.

E.ON Business is part of the E.ON SE 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

E.ON Business,pros and cons

E.ON Business is a credible Big Six choice for SMEs that want 100% renewable electricity bundled into a straightforward fixed plan, and one of the few large suppliers with serious advisory capacity for I&C buyers. The watch-outs are the standard ones for incumbent suppliers: the variable-plan rollover and the inability to leave a fixed contract early. Compare against at least one independent renewable specialist before signing.

Strengths

  • One of the historic Big Six with broad infrastructure and credit strength.
  • 100% renewable electricity included as standard on SME plans.
  • Tailored support and market-risk advisory for large industrial & commercial accounts.
  • Online portal with 24/7 self-service: payments, meter readings, contract renewal, moves.
  • Live chat available on the business website with fast response (often under a minute).

Watch-outs

  • Variable plans (the auto-rollover destination) are almost always more expensive than fixed.
  • Fixed contracts lock customers in until expiry, with no mid-term switching.
  • Customer service hours are office-only (Mon-Fri 9am-5pm), no weekend support.
  • Switching to E.ON Business takes around six weeks.

Renewables

E.ON Business green credentials

100% renewable electricity is standard for SME plans. Large I&C contracts can be configured for renewable supply but vary by contract.

Common questions

E.ON Business,frequently asked questions

E.ON Business 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. E.ON Business 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 plans of 1-3 years for SMEs; variable plans available; tailored contracts for I&C

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 E.ON Business on 0345 055 0065, Mon-Fri 9am-5pm. For a full breakdown of phone lines (sales, emergency, complaints, meter readings, account moves), see the E.ON Business contact page.
