Snapshot, in plain English
Is D-ENERGi 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. |

Company data
Live data on the licence-holding companies behind D-ENERGi, compiled by Purely Energy's independent research team and refreshed monthly.
D-ENERGi out-of-contract and deemed rates
Published deemed rates on the supplier website. As listed on the 2026 table: Gas 14.22 p/kWh in Jan-26, 14.92 p/kWh in Feb-26 and Mar-26, 16.62 p/kWh in Apr-26, 16.32 p/kWh in May-26; Electric NHH 50.53 p/kWh in Jan-26, 52.53 p/kWh in Feb-26 and Mar-26, 54.53 p/kWh in Apr-26, 54.03 p/kWh in May-26; Electric HH same as Electric NHH. Standing charge note: "Plus a standing charge rate 3.99 this may vary." If AQ is higher than 732,000kWh, a site-specific daily standing charge may apply. Electricity meters on deemed rates have a daily charge calculated specific to the site.
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 D-ENERGi may suit
Best fit for UK SMEs, multi-site businesses, and larger non-domestic users that want a brokered or supplier-direct quote for electricity and gas, including customers interested in renewable tariff options. The published website language also mentions care homes, hotels, manufacturing, schools, retail, and charities as served sectors.
Trading name and licence-holder notes
The website states that D-ENERGi is a trading name of UK Healthcare Corporation Limited. The company page also references "D-ENERGi Trading Ltd" in relation to the green tariff page, so the brand and legal-entity naming appears mixed across site pages; I have not assumed these are separate operating brands beyond what the site explicitly says.
Switching from D-ENERGi to a fixed business contract
UK businesses can switch electricity supply away from D-ENERGi 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 D-ENERGi. 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. D-ENERGi 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. D-ENERGi 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.

Does D-ENERGi publish out-of-contract rates?+
D-ENERGi 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 D-ENERGi?+
In most cases, businesses can switch electricity supply away from D-ENERGi 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 D-ENERGi?+
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 D-ENERGi a UK-licensed supplier?+
Yes. D-ENERGi 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.
