Ask five UK business owners what they pay per kWh and you will get five very different answers, often for near-identical premises. Business energy is priced individually — by consumption, location, credit profile and timing — which means published tariffs tell you little and quotes tell you everything. The only reliable way to know if you are overpaying in 2026 is to collect several quotes and compare them like for like. To save you trawling the whole market, here are ten names that should produce a representative spread: one comparison specialist that can gather most of the quotes for you, and nine suppliers whose pricing regularly features in competitive tenders.
1. Utility Bidder
Start with the quote-gatherer. Utility Bidder is a business energy broker — part of the Bionic family and among the most decorated brokers in the UK — that compares gas, electricity and water prices from a large supplier panel in one go. Instead of filling in nine separate forms, you give your details once and its team negotiates on your behalf, with claimed savings of up to 35% for businesses stuck on poor deals. Customer service is a highlight: the company holds an Excellent rating on Trustpilot, and reviewers often mention dealing with the same knowledgeable consultant year after year, which is rare in this market.
Honest caveats: brokers are typically paid through supplier commission, and a minority of customers felt this could have been flagged more plainly at the outset; a few also found the pace of the sign-up call brisk. Neither should stop you getting a comparison — just ask about commission and take your time.
2. British Gas Business
No quote round is complete without the biggest name in the market. British Gas Business covers every business size, offers fixed and variable products, and adds value through its engineer network and services like boiler cover. Its quotes are sometimes beatable, but they set a useful benchmark, and it occasionally sharpens its pencil for new business. Expect competent rather than personal service, and always compare its renewal offers before accepting.
3. ScottishPower
ScottishPower quotes competitively at tender, especially on longer fixed terms, and its green tariffs draw on one of the UK’s largest wind portfolios — useful if your customers ask about your carbon footprint. It handles everything from small shops to corporate estates. Its customer satisfaction scores trail the best challengers, so if service history matters to you, ask pointed questions about complaint handling before you commit.
4. Pozitive Energy
Pozitive Energy is one of the faster-growing SME suppliers and frequently undercuts bigger names for small and mid-sized accounts. It supplies gas, power and water, takes a smart-meter-first approach and is known for pragmatic credit terms. The brand is still unfamiliar to many business owners, and its track record is shorter than the established suppliers’, but on price alone it earns its place in any quote comparison.
5. EDF Energy
EDF brings stability to a quote round: strong finances, zero-carbon electricity backed by nuclear generation, and contract options that stretch from simple SME fixed deals to managed flexible purchasing. It suits businesses that want to sign and not worry. Its processes can feel slow and formal compared with digital challengers, and the smallest accounts do not always see its best pricing.
6. Octopus Energy
Octopus is worth quoting for the service alone. Bills are clear, support is fast, and 100% renewable electricity comes as standard rather than as a premium add-on. Small businesses and offices are the sweet spot. It offers less for large industrial users and complex multi-site portfolios, so bigger organisations should treat it as one quote among several rather than the likely winner.
7. TotalEnergies
For mid-market and larger businesses, TotalEnergies is a fixture on serious shortlists. It supplies a substantial share of UK commercial gas and electricity, offers flexible purchasing and consolidated multi-site billing, and is comfortable working through brokers. Microbusinesses are not its focus, and support for small accounts can feel thin relative to what its big customers receive.
8. SSE Energy Solutions
SSE Energy Solutions rounds out quotes for organisations with growing or complex needs: multiple sites, half-hourly metering, EV charging or on-site generation. Its business-only focus and renewable credentials are genuine strengths, and it is experienced with public-sector frameworks. Simpler businesses may find its proposals more elaborate than they need, and its small-account pricing is not always the keenest.
9. Yu Energy
Yu Energy gives quote rounds a challenger benchmark for bundled utilities: gas, electricity and water on one account, with UK-based support and plain fixed pricing aimed at SMEs. Firms that value a single point of contact rate it highly. Its range is narrower than the majors’, and very large users will outgrow it, but for straightforward small-business supply it regularly prices well.
10. Valda Energy
Valda Energy completes the ten. A newer business-only supplier, it moves quickly on quotes, uses smart metering as standard and will consider firms with limited credit history that others decline. That flexibility is its selling point. Its youth and firm payment terms are the counterweights, so read the contract terms as carefully as the price.
FAQ: getting and comparing quotes
How many quotes do I actually need? Three is a workable minimum; five or more gives a clearer picture. A broker comparison achieves the same spread with one conversation.
What information do I need to get a quote? Recent bills (or your MPAN/MPRN meter numbers), your annual consumption in kWh, your contract end date and your business details. Accurate consumption figures get you accurate quotes.
Why do quotes for the same business differ so much? Suppliers weigh credit risk, contract length, consumption profile and wholesale prices on the day differently. That variation is exactly why comparing pays.
Is the cheapest quote always the best? Not necessarily. Check standing charges, contract length, exit arrangements and service reputation alongside the unit rate.
Conclusion
Quotes are free; loyalty is not. Gather a handful of prices from the suppliers above — or let Utility Bidder collect and negotiate them for you in one pass — and you will know within days whether your current contract deserves to survive 2026.
