Who Limejump may suit

Best fit for renewable generators, battery/storage asset owners, PPA counterparties and other decentralised energy businesses rather than general SME electricity supply. The public rates page indicates out-of-contract and deemed terms exist, but the current website messaging suggests Limejump exited the small-scale PPA market and transferred out-of-contract customers to F&S Energy.

Trading name and licence-holder notes

The licence holder appears to trade as Limejump and is identified in official and company materials as Limejump Energy Limited. Public company context and Limejump's own site say it has been a wholly owned subsidiary of Shell since 2019 and part of Shell's Trading and Supply / Renewables & Energy Solutions operations. The site also notes a 1 May 2024 trade sale of out-of-contract import/export customers to F&S Energy Ltd.

Switching from Limejump to a fixed business contract

UK businesses can switch electricity supply away from Limejump 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 Limejump. 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 MPAN 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. Limejump 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. Settle the final bill and clear any objections. Limejump 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 Limejump brand?+

Does Limejump publish out-of-contract rates?+

Limejump 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 Limejump?+

In most cases, businesses can switch electricity supply away from Limejump 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 Limejump?+

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 Limejump a UK-licensed supplier?+

Yes. Limejump is on the Ofgem non-domestic licensee register for 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.
