While all UK energy suppliers sell the same electricity and gas (it all comes through the same National Grid infrastructure), they differ significantly in how they price, contract, and serve business customers. Understanding these differences helps you choose a supplier that fits your business needs.
The main areas where suppliers differ are: pricing structure (unit rates, standing charges, and how they bundle them), contract flexibility (fixed vs variable terms), renewable energy options (some suppliers offer 100% green energy as standard), customer service quality, billing transparency, and additional services like smart metering and energy monitoring tools.
| Factor | Why It Matters | What to Look For |
|---|---|---|
| Unit Rate (p/kWh) | The price per unit of energy used — the biggest cost factor | Lower is better, but check the standing charge too |
| Standing Charge | Daily fixed cost regardless of usage | Ranges from 20p to 60p+/day — matters for low-usage businesses |
| Contract Length | How long you're locked in for | 1-3 years typical; longer = more price security but less flexibility |
| Renewable Energy | Whether the electricity is from green sources | Some suppliers offer 100% renewable at no extra cost |
| Customer Service | How responsive and helpful the supplier is | Check Trustpilot reviews and complaint resolution data |
| Billing | How transparent and accurate bills are | Look for clear billing, monthly statements, online portals |
| Exit Fees | Penalties for leaving early | Some suppliers charge £25-50 per fuel per year remaining |
| Smart Meter Support | Whether they offer and support smart metering | Important for monitoring usage and identifying savings |
The UK business energy market includes both the 'Big Six' legacy brokers and a growing number of newer, often more competitive brokers. Each has different strengths:
British Gas: The largest supplier, offering a wide range of business tariffs and strong brand recognition. Good for businesses that want a familiar name, though not always the cheapest.
E.ON: Another major player with comprehensive business offerings, including green energy options and energy efficiency services.
EDF Energy: Particularly strong in large business and industrial energy, with expertise in half-hourly metering and complex contracts.
Octopus Energy: A newer supplier known for transparent pricing, excellent customer service, and 100% renewable electricity. Often competitive on price.
Shell Energy: Offers business energy with renewable options and integration with their broader energy services.
ScottishPower: Strong in Scotland and the North, with green energy options and a range of business tariffs.
Opus Energy: Focused specifically on SMEs, with flexible contracts and good customer service ratings.
TotalEnergies: Strong in commercial and industrial energy, with expertise in larger contracts and multi-site portfolios.
Many businesses are now choosing renewable energy brokers to reduce their carbon footprint and meet sustainability targets. The good news is that 100% renewable electricity is often available at the same price — or even cheaper — than standard tariffs.
When a supplier offers '100% renewable electricity', they match your consumption with Renewable Energy Guarantees of Origin (REGOs) certificates. This means that for every unit of electricity you use, an equivalent amount is generated from renewable sources (wind, solar, hydro) and fed into the grid.
Gas is harder to make renewable, but some suppliers offer 'green gas' where a percentage of your gas is matched with biogas (from anaerobic digestion) or carbon offsetting. We can advise on the best renewable options for your business.
Price isn't everything. A broker with the cheapest rates but terrible customer service can cost you more in time, stress, and unresolved billing issues. When evaluating brokers, consider: response times for queries and complaints, availability of a dedicated account manager (important for larger businesses), quality of online portals and apps, and transparency of billing.
We monitor customer service performance across all brokers and factor it into our recommendations. A broker might offer slightly higher rates but provide significantly better service — or vice versa. We help you balance price against service quality based on what matters most to your business.
The most effective way to compare energy brokers is to provide your latest energy bill to a independent broker. We can then pull real rates from a wide panel of UK suppliers simultaneously, tailored to your specific usage profile, and present a clear side-by-side comparison.
Don't rely on broker comparison websites that only show a subset of brokers or receive commissions for promoting certain ones. Use an independent broker who compares a wide panel of UK suppliers and is transparent about how they're paid (we're paid by the supplier you choose, through commission, never by you).
