Where your p/kWh actually goes

Indicative split for a UK I&C electricity bill in 2026, sourced from Cornwall Insight's non-commodity cost research. Your meter, region and contract type shift the exact mix, but the four components are always present.

  • Wholesale energy, 38%Gas or power bought on the wholesale market. The figure most coverage focuses on.
  • Non-commodity costs, 53%Network charges (DUoS, TNUoS), policy levies (RO, FiT, CfD, Capacity Market), CCL and balancing costs.
  • Supplier margin, 6%What the supplier earns. Always priced into the unit rate.
  • Broker margin, 3%What we earn for tendering and managing the contract. Shown separately on every Purely Energy quote.

Who Opus Energy may suit

Formerly fit for UK non-domestic and business customers, including SMEs and larger multi-site or higher-consumption sites. Current fit is limited because the website says the supplier is permanently closed and no longer accepting or renewing contracts.

Trading name and licence-holder notes

The business and energy brand is Opus Energy; Companies House identifies the legal entity as Opus Energy Limited (company number 04382246). The website also notes that most of the customer portfolio was sold to EDF and that new/renewing business contracts are no longer accepted. Older Ofgem correspondence shows Opus Energy and Opus Energy Gas as trading names associated with Opus Energy Limited and related group entities.

Switching from Opus Energy to a fixed business contract

UK businesses can switch gas and electricity supply away from Opus Energy once their fixed contract ends, or after resolving any open objection or termination-window issue. The process is the same for every supplier on the non-domestic market, but a few checks done in the right order make the transfer materially faster.

  1. 1. Find your contract end date. It's on your last renewal letter or the most recent bill from Opus Energy. Most non-domestic contracts have a 1 to 6 month termination window before that date, outside of which you may auto-roll onto a new fixed term.
  2. 2. Get your MPAN and MPRN ready. The 21-digit MPAN (electricity) and 6 to 10-digit MPRN (gas) uniquely identify each meter and are needed for any competing quote. Both appear on your bill.
  3. 3. Compare against the live market. Opus Energy publishes its out-of-contract rates online, so the gap between those and a current fixed offer is easy to quantify. Purely Energy can run your meters against the wider UK panel and come back with the cheapest fixed offers.
  4. 4. Settle the final bill and clear any objections. Opus Energy will issue a final bill within 6 weeks of supply transferring. If a balance is outstanding, they can object to the switch under industry rules, so clear it before the transfer date to avoid a hold.
  5. 5. Sign the new contract. Once the new supplier has your MPAN/MPRN and signed contract, the transfer typically completes within 4 to 8 weeks. There is no break in supply, you simply receive your first bill from the new supplier.

Opus Energy is the customer-facing trading name for a group of related Ofgem licences held by OPUS ENERGY LTD., OPUS ENERGY (CORPORATE) LTD. and OPUS GAS SUPPLY LTD.. Multiple licence holders is normal for larger UK energy groups and reflects how the supply business is structured for regulatory and operational reasons.

What is the Opus Energy business contact number?+

The official Opus Energy contact page is https://www.opusenergy.com/.

Does Opus Energy publish out-of-contract rates?+

Opus Energy publishes deemed or out-of-contract rates online. Always check the latest version on the supplier's own page before relying on them, since rates can change at short notice.

Can I switch away from Opus Energy?+

In most cases, businesses can switch gas and electricity supply away from Opus Energy at the end of a fixed-term contract or after resolving any objections, debt, termination-window, or meter-data issues. The safest route is to check your contract terms, final bill position, and renewal dates before starting a transfer.

How long does it take to switch from Opus Energy?+

Once a new supplier has the meter point details (MPAN/MPRN) and a signed contract, a non-domestic switch typically completes within 4 to 8 weeks. Supply does not break: the new supplier takes over billing on the transfer date.

Is Opus Energy a UK-licensed supplier?+

Yes. Opus Energy is on the Ofgem non-domestic licensee register for both gas and electricity. Ofgem maintains the official register at ofgem.gov.uk.

What are out-of-contract business energy rates?+

Out-of-contract rates are the prices a business pays when no fixed-term contract is in place with its supplier. They can be materially higher than negotiated contract rates, so businesses should check their contract end date and renewal window before they expire.
