A business energy quote is a snapshot of wholesale and non-commodity costs on a single day, dressed up as a contract offer. The number that lands in the inbox at 14:00 on a Tuesday is not the number that will land at 10:00 on Wednesday, and the difference is not a sales tactic: it is the supplier's wholesale desk repositioning. Getting an honest quote in 2026 means understanding the document chain (LOA, MPAN/MPRN, indicative, binding), the commission line that may or may not be disclosed, and the offer-validity window that turns a 48-hour quote into a hard expiry during volatile weeks.
TL;DR
- An indicative quote is not binding; a binding offer is typically valid 24-48 hours and is tied to the wholesale entry the supplier has locked for that contract.
- A Letter of Authority (LOA) lets a broker or new supplier pull MPAN/MPRN consumption data from the existing supplier and the data aggregator; without one, every quote is a guess.
- Ofgem's statutory consultation on third-party intermediary rule changes, launched 2026, proposes mandatory commission disclosure on quotes alongside a TPI licensing regime.
- A comparable quote must list: unit rate (p/kWh), standing charge (p/day), contract length, start date, non-commodity treatment (fixed or pass-through), broker commission, and offer-validity expiry.
- Going direct to a supplier (Octopus Energy for Business, British Gas Lite, EDF Business, E.ON Next Business publish direct routes) bypasses broker commission but only works if the procurement team can match the data quality the broker would have supplied.

How a quote is actually produced
A non-domestic energy quote is built from four data layers. The first is the supply point's identity: the Meter Point Administration Number (MPAN) for electricity, the Meter Point Reference Number (MPRN) for gas, the distribution network area, and the profile class (01-08 for non-half-hourly electricity, 00 for half-hourly). The second is the consumption history: usually 12 months of half-hourly or monthly data pulled from the data aggregator or the existing supplier. The third is the wholesale curve on the day of quoting, blended over the proposed contract length. The fourth is the supplier's margin plus non-commodity treatment.
Without MPAN-level data, any quote is an estimate against a notional consumption profile. Estimated quotes are routinely 10-25% off actual cost once true consumption flows through the bill, and the gap is usually the customer's problem, not the supplier's. The Citizens Advice consumer service has flagged estimated-quote disputes as a recurring source of small-business complaints in its quarterly reporting through 2024-2026.
In practice, the moment a quote becomes useful is the moment it is built against the actual MPAN consumption record. Anything before that is a price tile, not a procurement document.
The data layer is the quote, and everything else is sales packaging around it.
The LOA: what it does and where it bites
A Letter of Authority is a written instruction from the bill-payer authorising a third party to act on the site's behalf. There are three flavours that matter. A data-only LOA authorises retrieval of consumption history and meter data from the current supplier and the data collector. A full LOA authorises everything up to and including signing a new contract. A multi-supplier LOA authorises a broker to obtain quotes from a panel of suppliers in parallel.
The catch is that LOAs do not expire by default unless explicitly limited. A broker holding an open LOA from a 2024 renewal can still be in the supplier's system in 2026, receiving renewal triggers and quoting in the customer's name without the customer realising. Ofgem's non-domestic market review identified open-ended LOAs as a structural problem in the 2026 consultation paper and proposed time-limiting them under the incoming TPI code of conduct.
The workable habit is to issue LOAs with an explicit expiry date (typically 90 days for a procurement round, 12 months for an ongoing broker relationship) and to revoke any LOA in writing once a contract is signed and the procurement round is closed.
MPAN and MPRN: the data that makes a quote real
The MPAN is the 21-digit string at the bottom of an electricity bill, broken into a profile class, meter time switch code, line loss factor, distributor ID, and unique meter point reference. The MPRN is a shorter gas equivalent. Together they are the address the data flows through, and the data quality on a quote is the data quality of the MPAN pull.
For a single-site small business, the MPAN pull takes a few minutes and the consumption history comes back in 12 monthly readings. For a multi-site retail or hospitality group, the pull aggregates across distribution regions, profile classes, and metering types, and the quote that follows is only as accurate as the most patchy site in the portfolio. Tesco's 2023 procurement disclosure (in its annual report sustainability section) noted that portfolio-level energy procurement across more than 4,000 UK supply points required a dedicated data team and a multi-supplier framework rather than a single quote process.
For an MPAN in the South Western Electricity (Western Power Distribution) area, the line loss factor and distribution use-of-system charge differ from the same profile class meter in the London Power Networks area, and the quote reflects this. The supplier is not pricing a national average; it is pricing the actual MPAN's distribution geography.
Indicative vs binding: the difference that matters most
An indicative quote is a price illustration. It is built off either notional consumption or partial data, it is not tied to a specific wholesale lock, and the supplier can change the number at any point before signing. Most online "instant business energy quote" tools produce indicative numbers.
A binding offer is a specific unit rate, standing charge, and contract structure that the supplier is committed to honour if accepted within the offer-validity window. The supplier has either locked the wholesale position to back it or has agreed an internal risk allowance to hold it for the validity period. Outside that window, the offer lapses and the supplier reprices.
Here is where it breaks: a broker forwarding "your quotes" to a customer is sometimes forwarding indicative numbers labelled as if they were binding. The customer signs the LOA, the broker takes the quote to a supplier for binding, and the binding number comes back different. The gap is usually framed as "the market moved" but is just as often the gap between indicative and binding pricing.
The countermeasure is to ask explicitly: is this an indicative quote or a binding offer, and if binding, when does it expire.
A reputable broker or direct supplier desk answers in seconds.
A vague answer is itself the answer to the original question.
The 24-48 hour offer-validity trap
Business energy offers in 2026 are typically valid for 24 or 48 hours from issue. During calm wholesale weeks this is barely noticed; during volatile weeks it becomes a procurement bottleneck. A finance director who needs board sign-off on a multi-site contract cannot always close inside 48 hours, and the offer lapses.
The deeper trap is that the next offer is rarely the same number. If the wholesale curve has moved upward, the new offer is higher. If it has moved downward, some suppliers will requote at the new lower number, but others will not, citing the original offer as the "available rate" and pocketing the difference. Ofgem's non-domestic market review submissions from 2025-2026 included multiple supplier and intermediary statements on this dynamic.
The workable approach is to pre-stage the sign-off chain before requesting binding offers. The LOA is in place, the MPAN data is pulled, the contract terms are pre-reviewed, and the decision-maker is briefed and available. The binding offer arrives at 11:00, the decision is made by 16:00, and the contract is countersigned the next morning inside the 48-hour window.
Going direct: when it works, when it does not
Several major UK suppliers publish direct routes to a business energy quote in 2026. Octopus Energy for Business publishes its monthly rate sheet on its website; British Gas Lite, EDF Business, E.ON Next Business and SSE Business operate direct desks for small and mid-size customers. For a single-site small business with clean MPAN data and a willingness to pick up the phone, going direct removes the broker commission line entirely.
It does not always work cleanly. A non-microbusiness with multiple sites across different distribution regions, mixed metering types, and partial half-hourly coverage faces a different problem: the direct supplier desk will quote, but it will quote against its own panel of products, not against the wider market. The comparison work that a multi-supplier broker would do still needs doing, just internally.
The Federation of Small Businesses' policy submissions through 2025-2026 have flagged that under 35% of small-business energy contracts are negotiated direct, with the rest routed through brokers or auto-renewed. The asymmetry is partly a time problem and partly an information problem: most small businesses do not know they can request a bill-validation rate directly from the supplier.
What a quote must contain to be comparable
A comparable quote is a quote that lines up against another quote field by field without translation. The minimum field list is short.
Unit rate in p/kWh, to three decimal places for accuracy. Standing charge in p/day. Contract start date and end date, not just a duration. Estimated annual consumption (EAC) the supplier has used in the calculation, taken from the MPAN pull. Treatment of each non-commodity element (CCL, capacity market, BSUoS, RO, FiT, DUoS, TNUoS) as either fixed-in or pass-through. Broker commission, in either p/kWh uplift or flat fee, if any third party is involved. Offer-validity expiry, in date and time, not "valid for 24 hours from now".
| Quote field | What it means | What to check |
|---|---|---|
| Unit rate (p/kWh) | Cost per kWh consumed | Three decimal places; same metric as comparator |
| Standing charge (p/day) | Fixed daily cost | Regional variation; sometimes negotiable on direct quotes |
| EAC (kWh/yr) | Estimated annual consumption | Pulled from MPAN data, not notional |
| Contract dates | Start and end | Specific calendar dates, not "12 months from acceptance" |
| Non-commodity treatment | Fixed or pass-through per element | Listed line by line, not bundled as "fully-fixed" |
| Broker commission | Third-party fee in the price | Disclosed in p/kWh or flat fee, in writing |
| Offer-validity expiry | When the offer lapses | Specific date and time, not relative |
| Indicative or binding | Status of the quote | Stated explicitly |
Quotes that omit fields are not comparable. A quote with a unit rate and a standing charge but no statement on non-commodity treatment can be 10-15% off the true total. A quote with no offer-validity expiry is either indicative (the supplier can change it) or operating outside the supplier's own normal control framework (a problem in its own right).
Commission disclosure under the incoming TPI rules
Ofgem's statutory consultation on third-party intermediary rule changes, launched 2026 under the non-domestic market review work programme, sets out three core proposals. First, a TPI licensing regime, bringing brokers and consultants into Ofgem's direct regulatory perimeter for the first time. Second, mandatory commission disclosure on every quote, in writing, before signing. Third, a code of conduct enforceable by Ofgem with redress through the Energy Ombudsman extended to non-microbusiness customers in scope.
The consultation closed in spring 2026 with implementation expected in stages from late 2026 into 2027. The practical effect, when it lands, is that the broker commission line will move from a buried per-kWh uplift to a disclosed figure on the quote document. The customer will see the number. The number will be debatable. The asymmetry that has propped up the broker-bait quote economy for two decades narrows.
Citizens Advice and the Federation of Small Businesses have both submitted to the consultation in support of disclosure. The major broker trade bodies have submitted, broadly, in support of licensing while pushing back on the format of disclosure. The shape of the final rules will be set by Ofgem during 2026.
Five tactics for getting honest quotes in 2026
Tactic one: issue time-limited LOAs. A 90-day data-only LOA covers a procurement round without leaving the supplier or broker with open-ended authority.
Tactic two: pull the MPAN consumption history directly from the existing supplier portal before any third party gets the LOA. The data sits in the existing portal already; pulling it removes a step and a friction.
Tactic three: ask explicitly for indicative vs binding status on each quote, and the offer-validity expiry. The answer to this question is itself a signal of how the counterparty operates.
Tactic four: ask for the supplier's bill-validation or direct rate alongside the broker quote. The gap is the commission. The gap, in 2026, is increasingly something a broker is willing to discuss because the TPI rules are coming.
Tactic five: pre-stage the sign-off chain before the binding offer is requested. The window is 24-48 hours; the internal decision process needs to fit inside it.

Frequently asked questions
What is the difference between an indicative and a binding business energy quote?
An indicative quote is a price illustration the supplier can change at any point; a binding offer is a specific rate the supplier is committed to honour inside an offer-validity window, typically 24-48 hours. Online "instant quote" tools almost always return indicative numbers.
Do business energy quotes have to disclose broker commission?
Not yet universally, but Ofgem's 2026 statutory consultation on third-party intermediary rule changes proposes mandatory commission disclosure on every quote in writing before signing. Implementation is expected in stages from late 2026 into 2027.
How do MPAN and MPRN data affect the accuracy of a quote?
MPAN (electricity) and MPRN (gas) are the unique identifiers for each supply point and the route to actual consumption history from the data aggregator. A quote built off real MPAN data is materially more accurate than one built off notional consumption; Citizens Advice has flagged estimated-quote disputes as a recurring small-business issue through 2024-2026.
Can a business get a quote direct from a supplier without a broker?
Yes. Octopus Energy for Business, British Gas Lite, EDF Business and E.ON Next Business all operate direct desks and publish small-business rates. Going direct removes broker commission but requires the customer to do the multi-supplier comparison work internally.
Why are business energy offers only valid for 24-48 hours?
The offer is tied to a specific wholesale lock the supplier has either taken or held risk capital against. Outside the validity window the wholesale curve has moved and the supplier reprices, which is why pre-staging the sign-off chain before requesting binding offers matters during volatile weeks.
What should an LOA include?
Scope (data only, full, single supplier or panel), a specific expiry date, and a revocation clause. Ofgem's 2026 consultation on TPI rules flagged open-ended LOAs as a structural problem and proposed time-limiting them under the incoming code of conduct.
