Next update: when Corona reprints contract product pages or Ofgem updates non-domestic supplier lists.
By: Switch Editorial Team, Switch Squid Ltd
As of 23 September 2026, Corona Energy is an established independent UK non-domestic gas and electricity supplier (Corona Energy Retail licence entities; Macquarie group ownership context) serving SMEs, corporates and public-sector sites — if you are comparing business tariffs, start with a multi-quote process rather than a domestic SVT mindset. Primary CTA is SwitchSquid’s own business energy form only — never MoneySuperMarket residential Awin links on this page.

Who Corona Energy is
Corona describes itself as a leading independent commercial energy supplier with around 30 years in the market, citing a portfolio on the order of 13,000+ customers and 85,000 meters (company materials). The group’s Consolidated Segmental Statement lists supply segments under Corona Energy Retail 1–4 Limited for gas and electricity supply activities. That is non-domestic supply — not a household SVT brand.
Public materials emphasise fixed and flexible contracts, quotes within about 48 hours, dedicated account management, and the myCorona online portal for meter reads, usage and pricing visibility. Public-sector framework experience and green gas / REGO / PPA options appear in their sector pages — always confirm current products on coronaenergy.co.uk before you assume a tender packs them in.
Business vs domestic — do not mix
Residential Ofgem price-cap maths (£1,723 dual-fuel DD for Oct–Dec 2026) does not apply to most business sites. Non-domestic contracts are quote-led, often with longer notice, volume tolerances, and pass-through of industry charges. Using a household comparison site for a warehouse MPAN is the wrong tool.

When Corona is on the shortlist
Put Corona on the list when you want an independent commercial specialist rather than a Big Six residual brand, when you need both gas and power under one commercial relationship, or when public-sector framework familiarity matters. Multi-site portfolios should ask about consolidated billing and myCorona access for local managers.
Skip Corona (or any single supplier) as a sole bid if your procurement policy requires three unrelated quotes, or if your load shape needs a fully flexible trading desk you have not scoped yet. Flexible contracts without a risk policy are how finance teams get surprised.
What to prepare before a quote
- MPAN / MPRN list and half-hourly or monthly consumption history (12–36 months).
- Current contract end dates and notice periods.
- Site addresses, capacity / ASC figures, and any HH vs NHH meter mix.
- Budget vs risk preference: fixed, flex, or hybrid.
- Sustainability requirements (REGO, green gas, PPA interest).

FAQ
Is Corona Energy a domestic supplier?
No — Corona’s published positioning is commercial / non-domestic supply via its Retail licence entities.
Can I use the Ofgem £1,723 cap for my shop?
Almost never. That figure is a typical domestic Direct Debit dual-fuel cap for Oct–Dec 2026. Business sites need commercial quotes.
How do I get a Corona quote via SwitchSquid?
Use the business energy form. We do not place residential MSM links on business guides.
Does Corona offer green energy?
Company materials reference green gas certificates, REGO electricity and PPAs — confirm live product availability for your tender.
Who owns Corona?
Segmental statements describe Macquarie Corona Energy Holdings Ltd in the group structure. Ownership context can change — verify Companies House / latest CSS if it matters to procurement.
What if I only have one site under 50,000 kWh?
You may still be non-domestic. Micro-business protections differ from household rules — still use a business quote path.

Procurement checklist
1) Diary contract end dates 120 days out. 2) Collect HH data early. 3) Run at least three quotes (Corona + two others). 4) Compare standing, unit, flexibility fees, and credit terms — not just a headline p/kWh. 5) Check pass-through of TNUoS/DUoS/BSUoS style charges on flex deals. 6) Sign with a named risk owner in finance.

Honest limits
We are not Corona’s broker of record on every tender, and we cannot see your HH shape from this blog. Business energy prices move with wholesale and your credit file. Soft hub copy never replaces the form CTA. Residential MSM journeys belong on /energy/guides/ only.
Multi-site and public sector notes
Multi-site portfolios should ask how Corona consolidates invoices and whether myCorona roles can be delegated per site. Public-sector buyers should request framework references and bid-support contacts rather than a generic SME web quote. Emergency numbers remain national: gas 0800 111 999, power 105 — those are not supplier sales lines.
Fixed vs flexible commercial contracts
Fixed business contracts lock a unit price for a defined volume band and term. Flexible contracts track wholesale with purchasing decisions across the curve. Hybrids fix a baseload and flex the rest. Finance teams that want budget certainty usually start fixed; teams with a trading policy and HH data can earn from flexibility — or lose it. Corona’s public materials advertise both fixed and flexible options; your quote will spell out which levers you actually get.
Volume tolerance clauses matter. Under-consuming a take-or-pay style band wastes money; over-consuming can spill onto expensive out-of-contract rates. Model a mild recession case and a growth case before you sign.
Credit, deposits and payment terms
New company numbers and thin credit files attract deposits or tighter payment terms. That is normal in non-domestic supply. Ask for the credit rationale in writing and whether a parent-company guarantee changes the deposit. Direct Debit discounts sometimes exist — confirm they are not clawed back on a single failed collection.
Late payment administration fees appear in segmental statements as other revenue for many suppliers. Build a calendar so invoice queries happen before the due date, not after.
Metering, HH data and myCorona
Half-hourly sites should export HH CSV files before tender. NHH sites should still provide 12–36 months of bills. myCorona-style portals help local managers submit reads and spot anomalies early. If your sites mix HH and NHH, say so up front — pricing and forecasting differ.
AMR / smart metering rollouts can change how quickly invoice disputes resolve. Ask who owns the meter asset and who books engineers when a read fails.
How SwitchSquid stays on the business track
Basith’s hard rule from 22 September 2026: residential and business energy guides stay fully separate. Home guides live under /energy/guides/ with MSM Awin CTAs. Business guides live under /business-energy/guides/ with the own form only. This Corona page follows that rule even when October’s domestic cap is the loud news cycle.
Near-tier reading includes Pozitive Energy on the same business track. Do not deep-link a Corona explainer into a household fixed-vs-SVT money button.
Tender timeline example
Day 0–7: gather HH data and contract end dates. Day 7–14: issue RFQ to Corona plus two competitors via the SwitchSquid form and any incumbent broker. Day 14–21: compare like-for-like (standing, unit, flex fees, credit). Day 21–28: legal redlines and signature. Starting 30 days before a contract ends is how you end up on expensive out-of-contract rates — start earlier for multi-site.
Risk policy one-pager for directors
Before any flex contract, write a one-page risk policy: who can buy, max tenor, stop-loss rules, and reporting cadence to the board. Corona or any supplier can execute within that policy — they cannot invent your governance. SMEs without a policy should prefer fixed terms until someone owns the wholesale risk explicitly.
Insurance, business interruption, and force-majeure clauses in the supply agreement deserve a solicitor pass on large loads. Template SME contracts are fine for micro sites; multi-million kWh portfolios are not DIY.
Finally, keep residential staff benefits (employee home energy) off this commercial tender. Employee home switches belong on the MSM residential journey, not on the Corona business account.
Out-of-contract rates and renewal discipline
Landing on out-of-contract or deemed rates after a missed renewal is one of the most expensive mistakes in SME energy. Diary renewal 120 days out, assign an owner, and refuse last-minute single-bid pressure. Corona’s quote turnaround claim of about 48 hours only helps if you sent clean data weeks earlier.
If you inherit a site mid-lease, request the last invoice and contract end date from the landlord or previous tenant immediately — do not wait for the first shocking bill.
