Trading name and licence-holder notes

Switching from OSSO Energy to a fixed business contract

UK businesses can switch gas supply away from OSSO 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 OSSO 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. OSSO 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. OSSO 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 OSSO Energy brand?+

The Ofgem non-domestic licence is held by Osso Energy Plc, ultimately part of OSSO ENERGY PLC (Company No. 09064653). 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 OSSO Energy business contact number?+

The official OSSO Energy contact page is https://www.ossoenergy.com/contact.

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

OSSO 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 OSSO Energy?+

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

Yes. OSSO 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.
