Company data
Live data on the licence-holding companies behind Ceres Energy, compiled by Purely Energy's independent research team and refreshed monthly.
Ceres Energy out-of-contract and deemed rates
Not publicly published / quote required. The deemed contract scheme says charges are applied in accordance with Ceres’ “Deemed Rates” as published on the website, but the accessible document does not show specific rate values, units, standing charges, or effective dates.

If you are on deemed, default, rollover, variable, or Out-of-contract rates, ask for a written renewal quote and compare it against live market prices before agreeing a new contract.
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 Ceres Energy may suit
Best fit for business and industrial gas users, biomethane producers, transport fuel/gas shipping arrangements, and other non-domestic customers needing tailored commercial gas supply and market services rather than standard mass-market tariffs.
Trading name and licence-holder notes
The licence holder appears to trade as Ceres Energy / Ceres; published documents identify the legal entity as Ceres Energy Limited. A 2024/2025 CSS filing also references the group including Barrow Shipping Limited. I found no evidence that the company trades under a substantially different consumer-facing brand.
Switching from Ceres Energy to a fixed business contract
UK businesses can switch gas supply away from Ceres 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. Find your contract end date. It's on your last renewal letter or the most recent bill from Ceres 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. Get your 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. Compare against the live market. Ceres Energy doesn't publish standard out-of-contract rates, so request a written renewal quote first and benchmark it against live market prices before agreeing anything. Purely Energy can run your meters against the wider UK panel and come back with the cheapest fixed offers.
- 4. Settle the final bill and clear any objections. Ceres 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. 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.

FAQs
Who supplies energy under the Ceres Energy brand?+
The Ofgem non-domestic licence is held by CERES ENERGY LTD., ultimately part of Ceres Energy Limited (Company No. 06490828). The trading name on your bill or contract may differ from the licence holder, which is normal and reflects how UK energy is regulated.
What is the Ceres Energy business contact number?+
Ceres Energy can be reached on +44 1434 602 700 or by email at info@ceresenergy.co.uk. The official contact page is https://ceresenergy.co.uk/contact/.
Does Ceres Energy publish out-of-contract rates?+
Ceres Energy does not appear to publish a standard deemed or out-of-contract rate online. Business customers should request a written renewal quote in advance of their contract end date and compare it against live market prices.
Can I switch away from Ceres Energy?+
In most cases, businesses can switch gas supply away from Ceres 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 Ceres 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 Ceres Energy a UK-licensed supplier?+
Yes. Ceres Energy is on the Ofgem non-domestic licensee register for gas. 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.
