Commercial energy comparison for UK businesses
Compare whole-of-market business electricity and gas options with a clear, UK-specific process. Get quotes, understand contract terms, and switch (or renew) with confidence—whether you’re a microbusiness or a multi-site organisation.
- Whole-of-market comparison: prices, contract length, T&Cs and supplier options
- UK-specific checks: meter type (HH/NHH), rates, standing charges, VAT/CfD/RO and contract end dates
- Helpful guidance: pitfalls, exit fees, auto-rollovers, tenancy and landlord considerations
Estimates only. Prices and availability vary by meter type, usage, location, credit checks and contract terms.
Fast answer: commercial energy comparison
Commercial energy comparison is the process of checking multiple UK business electricity and gas contracts to find a tariff that fits your usage and risk appetite; the most important step is confirming your contract end date before requesting quotes. You compare unit rates, standing charges, contract length, fees and meter type, then switch or renew.
Key caveat: Business energy isn’t priced like domestic energy. Quotes can differ by meter profile (HH/NHH), location, consumption pattern, credit checks, and whether you’re renewing or switching supplier.
Key takeaways
- Start early: many businesses review 60–120 days before renewal to avoid rushed decisions.
- Check your meter type: Half-hourly (HH) meters price differently from non-HH.
- Compare more than p/kWh: standing charges, pass-through charges, payment method and terms matter.
- Understand contract risk: fixed vs flex vs pass-through can change monthly costs.
- Know your status: microbusinesses have extra protections in parts of the switching process.
How commercial energy comparison works (UK)
A useful comparison starts with accurate inputs. Business suppliers price risk differently depending on your meter type, consumption pattern and credit profile—so getting the basics right improves quote quality and avoids surprises later.
- Gather essentials: business address and postcode, current supplier, contract end date, meter numbers (MPAN for electricity, MPRN for gas) and recent bills if available.
- Confirm your meter set-up: half-hourly vs non-half-hourly, single-rate vs day/night, and whether you have smart/AMR/AMI reads.
- Choose the right contract type: fixed (budget certainty), flex (market-linked), or pass-through (variable non-energy costs). Terms vary by supplier.
- Review the full cost: unit rate, standing charge, payment method, fees, billing cadence, and any pass-through elements.
- Switch or renew: once you accept, suppliers handle registration; timelines vary by meter and status. Always check any termination notice periods.
Good to know: If you’re in leased premises or a managed workspace, confirm who is contractually responsible for energy. Sometimes energy is bundled into service charges, and a “switch” may not be possible.
What you’ll need (quick list)
Get quotes (no obligation)
Share a few details and we’ll help you compare commercial energy options. We use your info to request suitable quotes and explain key terms—especially around renewal dates, fees and meter type.
Microbusiness protections (why we ask the right questions)
If your business is classed as a microbusiness, some rules and supplier processes differ. Definitions and protections can depend on usage and staff numbers—so we’ll confirm eligibility based on the information you provide and supplier criteria.
What to compare (and why it changes your total cost)
Two quotes can look similar on unit rate, but land very differently on your bill once standing charges, pass-through costs, payment method and terms are included. Use the table below to compare like-for-like.
| Compare item | What it means | Why it matters |
|---|---|---|
| Unit rate (p/kWh) | Price per unit of energy used (may be single rate or day/night). | Main driver of cost, especially for higher-usage sites. |
| Standing charge | Fixed daily cost for keeping the supply active. | Big impact on low-usage sites (offices, small retail, seasonal businesses). |
| Contract length | Commonly 12–36 months (sometimes longer for certain profiles). | Longer terms can reduce volatility but may increase exit costs and limit flexibility. |
| Fees & terms | Termination fees, deemed rates, auto-renewal/rollover clauses, late payment terms. | Can outweigh any headline price advantage if circumstances change. |
| Meter type (HH/NHH) | Half-hourly meters record usage every 30 minutes; others are profiled/estimated between reads. | Affects how suppliers price risk and can change day/night or peak/off-peak value. |
| Pass-through vs all-inclusive | Some contracts bundle non-energy charges; others bill certain charges separately. | Impacts bill predictability and how you compare quotes (you need like-for-like assumptions). |
Decision checklist: who commercial comparison suits
- You know (or can find) your contract end date and want to avoid rollover/deemed rates.
- You have at least one recent bill or annual kWh estimate.
- You want to compare fixed vs flexible options based on your cashflow and risk tolerance.
- You manage multiple sites and need consistent terms and billing where possible.
When it may not be straightforward
- Energy is included in rent/service charges (you may not be the bill payer).
- You’re in a short-term lease and need a very specific contract length.
- You have complex metering (sub-meters, landlord supplies, embedded networks).
- You’re in debt or have changing occupancy—supplier acceptance may vary.
In these cases, you can still compare—just expect extra questions so quotes match your real supply set-up.
Two realistic scenarios (with numbers)
These examples show how small differences in rates and standing charges can change annual cost. They are illustrative estimates (not predictions). They exclude VAT and any site-specific pass-through charges unless stated.
Scenario A: small office (electricity only)
- Assumptions
- Non-HH meter, single rate, 12,000 kWh/year.
- Quote 1
- 27.0p/kWh + 60p/day standing charge
- Quote 2
- 26.0p/kWh + 95p/day standing charge
- Estimated annual cost comparison
- Quote 1: (12,000×£0.27) + (365×£0.60) ≈ £3,459
Quote 2: (12,000×£0.26) + (365×£0.95) ≈ £3,467
What this shows: for lower usage, a higher standing charge can wipe out a cheaper unit rate.
Scenario B: small restaurant (electricity + gas)
- Assumptions
- Electricity 45,000 kWh/year; gas 30,000 kWh/year; fixed 24-month term; standing charges shown.
- Bundle Quote 1
- Elec 25.5p/kWh + 75p/day; Gas 6.8p/kWh + 35p/day
- Bundle Quote 2
- Elec 26.2p/kWh + 55p/day; Gas 6.5p/kWh + 45p/day
- Estimated annual cost comparison
- Quote 1 ≈ (45,000×£0.255 + 365×£0.75) + (30,000×£0.068 + 365×£0.35) ≈ £14,048
Quote 2 ≈ (45,000×£0.262 + 365×£0.55) + (30,000×£0.065 + 365×£0.45) ≈ £14,099
What this shows: once you combine fuels, you should compare total annualised cost, not “best electricity rate” in isolation.
Important: Actual bills may include other charges (for example, network charges and policy costs), and VAT treatment depends on eligibility (e.g., reduced rate for qualifying use). Always review the full quotation and contract summary.
Costs, exclusions and common pitfalls (UK business energy)
Commercial contracts can be straightforward once you know what to look for. These are the most common areas that cause unexpected costs, delays or mismatched quotes.
1) Deemed and out-of-contract rates
If you move in, take over a supply, or your contract ends without a new one agreed, you can be placed on deemed rates. These can be higher and vary by supplier. Confirm responsibility when taking on premises.
2) Termination notice and auto-rollovers
Some contracts require notice to prevent rollovers or to renew on time. Always check your agreement and any renewal communications. Missing a notice window can reduce your options or add fees.
3) Exit fees and contract flexibility
Fixed-price deals often include termination charges if you leave early, close a site, or significantly change usage. If you may relocate, consider shorter terms or clarify assignment/novation options.
4) Metering and estimated reads
Incorrect meter details (or missing reads) can lead to estimated billing and delayed switches. If you can, take a meter read on move-in, keep a photo, and ensure MPAN/MPRN details match your bills.
5) VAT and eligibility
Business energy VAT treatment can vary depending on use and eligibility for reduced rates. If you think you qualify, you may need to provide evidence or complete supplier forms.
6) Pass-through charges and “like-for-like” comparisons
Some quotes include certain non-energy costs; others pass them through at cost. If you compare two deals with different structures, the cheapest-looking rate might not be cheapest overall.
Tip for multi-site businesses: Ask whether quotes assume consolidated billing, site-by-site invoices, and whether contract start dates align across locations. Small admin differences can become costly at scale.
Commercial energy comparison FAQs
When should I compare business energy deals before renewal?
A practical window is often 60–120 days before your contract end date, because suppliers may price ahead and you have time to check terms and any notice periods. The right timing depends on your current contract rules, meter type and supplier processes.
What information do I need to get a commercial energy quote?
Usually: business postcode and address, MPAN (electricity) and/or MPRN (gas), current supplier, contract end date, and your annual kWh (or a recent bill). If you have multiple sites, you’ll need these details per meter.
What’s the difference between half-hourly (HH) and non-HH meters for pricing?
HH meters record electricity usage every 30 minutes, so suppliers can price based on your consumption shape (peak vs off-peak). Non-HH meters are often priced using profiles and periodic reads. This can materially change which contract type and rates are competitive.
Can I switch business energy if I rent my premises?
Sometimes. If your business is the bill payer and named on the energy account, switching is usually possible (subject to contract terms). If energy is included in rent/service charges or controlled by a landlord/managing agent, you may not be able to switch the supply directly.
Are business energy contracts covered by the Ofgem price cap?
No. The Ofgem price cap applies to default domestic tariffs, not most business energy contracts. Business pricing is typically contract-based and can vary widely by meter type, usage and credit profile.
Do I have to pay exit fees to switch business energy?
Not always, but many fixed-term contracts include termination fees if you leave before the end date or outside allowed windows. The amount and rules vary by supplier and contract, so you should check your agreement and confirm before accepting a new deal.
Is a fixed-rate or flexible business energy contract better?
It depends on your priorities. Fixed-rate contracts can make budgeting easier but may include exit fees. Flexible or market-linked contracts can suit larger or more sophisticated buyers who can tolerate price movement. Your meter type, cashflow needs and appetite for risk should guide the choice.
How long does a business energy switch take in the UK?
Timelines vary by supplier, meter type and contract dates. In many cases, the new contract is set to start at (or just after) your existing contract end date, rather than immediately. If there are data issues (wrong meter details, disputed occupancy), switching can take longer.
Trust, methodology and limitations
How we assess commercial energy comparison
This guide is written to help UK businesses make better decisions, not to push a one-size-fits-all tariff. We focus on the variables that most affect total billed cost and switching outcomes.
- Total cost view: we prioritise comparisons that include unit rates and standing charges, plus an explanation of pass-through vs bundled structures.
- Contract reality: we highlight notice periods, termination fees, deemed rates and common contract pitfalls that can materially affect outcomes.
- UK specifics: we reference Ofgem and UK consumer guidance, and we call out microbusiness considerations where relevant.
- Assumptions in examples: scenarios use simple annualised maths (kWh × unit rate + daily standing charge × 365). They exclude VAT and site-specific charges unless stated.
Limitations: Supplier pricing and acceptance can change quickly, and quotes can differ based on credit checks, payment method, meter data quality, and consumption shape (especially for HH meters). Always read the final quote and contract documentation before agreeing.
