COMPARE checklist: a named framework to evaluate quotes

Use the COMPARE framework to review any business energy quote consistently.

• Contract length – Fixed or variable and automatic renewals.
• Other charges – Standing charges, meter fees, VAT treatment.
• Meter and consumption accuracy – Correct MPAN/MPANs, half-hourly vs non-half-hourly.
• Price structure – Unit rate, wholesale pass-through, green levies.
• Administrative terms – Billing frequency, payment method discounts.
• Renewal and exit clauses – Notice periods and exit fees.
• Energy support – Account management, dispute resolution process.

How to use these sites and compare results (practical steps)

Start by collecting recent energy bills and confirming meter IDs. Enter identical consumption data on multiple platforms to ensure like-for-like comparisons. Pay attention to fixed vs variable tariffs and whether quotes include pass-through costs tied to wholesale markets.

Practical tips

• Run quotes on at least three different types of services: aggregator, broker, and direct supplier portal.
• Check renewal and exit terms on the small print—savings on unit rates can be offset by high exit fees.
• Prefer suppliers that can handle the correct meter type (half-hourly for larger sites); incorrect meter setup often causes billing errors.
• Ask for itemised sample invoices if switching to a new supplier to verify billed components match the quote.

Trade-offs and common mistakes

Common mistakes include comparing headline unit rates without factoring in standing charges, or failing to confirm whether a quote is a firm offer or subject to credit checks. Trade-offs often involve price vs. service: the cheapest tariff may have poorer account support or stricter exit clauses. For regulated guidance on switching and customer protections, refer to Ofgem's resources (Ofgem).

Short real-world scenario

A small café with a single non-half-hourly meter used these steps: collected 12 months of bills, ran quotes on a broker marketplace, an aggregator and directly with two suppliers, applied the COMPARE checklist, checked exit fees, and chose a 12-month fixed tariff with clear billing. The process highlighted a hidden daily standing charge on one cheaper quote that erased expected savings.

FAQ

How can a business compare business gas and electricity prices UK effectively?

Use at least three sites (aggregator, broker, direct supplier), collect recent bills for accurate consumption, apply a checklist like COMPARE to review contract length, other charges, and exit terms, and verify meter types before accepting an offer.

Are comparison sites accurate for complex multi-site businesses?

Many comparison tools are designed for single-site or standard profiles. For complex or multi-site portfolios, use a broker or a tender platform that can handle bespoke contracts and negotiate commercial terms.

Do brokers charge fees and are they worth it?

Brokers may charge fixed fees or receive commission from suppliers; these costs should be transparent. Brokers can add value by handling procurement, credit checks, and bespoke contract negotiation for larger or complex accounts.

What should be checked on the fine print of commercial energy quotes?

Inspect renewal clauses, automatic roll-over terms, exit fees, billing frequency, and whether the quoted price is guaranteed or subject to market adjustments (wholesale pass-through).

How do half-hourly meters change the comparison process?

Half-hourly meters allow more granular pricing and can be required for larger consumption profiles; ensure the quoting tool or supplier supports half-hourly settling to avoid inaccurate estimates.
