PX Supply Ltd business energy supplier profile
PX Supply Ltd is a UK electricity supplier licensed for non-domestic supply, registered at PX House in Stockton-on-Tees and operating within the PX group ecosystem. Publicly available official sources show it as an active electricity trading entity, but I did not find a customer-facing website page with published business tariffs or out-of-contract rates.

Snapshot, in plain English
Is PX Supply Ltd right for your business?
Licensed for 9 years, accounts currently filed. Independent sizing not yet published. Treat as a smaller licensed supplier until verified: fine for single-site SME contracts subject to credit checks, but extra diligence is warranted before a multi-year commitment above £100k spend.
Risk band reasoning: Active, 9 years trading, accounts current.
| Your business | Fit | Why |
|---|---|---|
| Single site SME | Fit | Often the segment these suppliers target. |
| Multi-site SME | Possible | Check multi-site billing capability and credit limits. |
| I&C £250k to £1m spend | Not suited | Counterparty failure risk too high for this commitment size. |
| I&C above £1m spend | Not suited | Not viable at this scale. |

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 PX Supply Ltd may suit
Best suited to UK non-domestic electricity customers looking for business supply from an established licensed trader; however, without public rate sheets it appears to work on quote-based, account-managed pricing rather than transparent online tariff publication.
Trading name and licence-holder notes
The licence context suggests PX Supply Limited may sit under the PX / Coulomb Energy Supply Limited group structure: Ofgem lists Coulomb Energy Supply Limited as the encompassing licence holder for PX Supply Limited, while the group privacy policy identifies Coulomb Energy Supply Limited within px group and gives the PX Limited website and contact details. I did not find evidence that PX Supply trades under a separate consumer-facing brand beyond the PX / PX Limited group identity.
Switching from PX Supply Ltd to a fixed business contract
UK businesses can switch electricity supply away from PX Supply Ltd 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 PX Supply Ltd. 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. PX Supply Ltd 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. PX Supply Ltd 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.
