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 Jellyfish Energy may suit

Best fit for SMEs and larger business customers that want a quoted or bespoke supply agreement, including multi-site requirements and flexible renewable options. Less suited to buyers looking for a fully transparent public tariff sheet for business supply, as commercial pricing appears quote-led.

Trading name and licence-holder notes

The official site and terms identify the trading name as Jellyfish Energy and the legal entity as Jellyfish Energy Limited. Ofgem’s company page lists Jellyfish Energy Limited under company number 09310083, while Companies House shows the registered office at Baird House, Scotswood Road, Newcastle Upon Tyne NE4 7DF. No clear evidence was found that the licence holder trades under a different brand.

Switching from Jellyfish Energy to a fixed business contract

UK businesses can switch gas and electricity supply away from Jellyfish 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 Jellyfish 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. Jellyfish 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. Jellyfish 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.

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

Jellyfish 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 Jellyfish Energy?+

In most cases, businesses can switch gas and electricity supply away from Jellyfish 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 Jellyfish 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 Jellyfish Energy a UK-licensed supplier?+

Yes. Jellyfish 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.
