Business gas prices: what you’ll pay and how to compare
Get a clear view of current business gas pricing (unit rate + standing charge), what drives it, and how to compare quotes confidently across UK suppliers.
- Understand what business gas prices include (and what they don’t)
- See realistic example costs with transparent assumptions
- Compare contract types and know what to ask suppliers/brokers
Prices are estimates and vary by meter type, usage, location, credit checks and contract terms. We show methodology and limitations below.
Fast answer: what are business gas prices in the UK?
Business gas prices are usually quoted as a unit rate (p/kWh) plus a standing charge (p/day), then billed with VAT and any agreed extras. Unlike domestic energy, business gas is typically contract-based (fixed-term), and your final rate depends heavily on your annual consumption, meter type (e.g. non-half-hourly vs large supply point), site location, credit profile and contract length.
What you’ll see on a quote
- Unit rate (p/kWh)
- Standing charge (p/day)
- Contract length + end date
- Payment method (DD/BACS)
Biggest price drivers
- How much gas you use (AQ)
- Meter class / supply point
- Region & network charges
- Credit checks / deposit
How to get the best fit
- Start 8–12 weeks before renewal
- Compare like-for-like terms
- Check pass-through vs all-inclusive
- Confirm exit fees and read rates
Important: There isn’t one “standard” business gas price for everyone. Even two firms in the same town can receive different rates due to usage profile, meter setup and credit assessment. Use comparisons to narrow your options, then confirm the full quote details before you agree.
Compare whole-of-market business gas quotes
Tell us a few details and we’ll match you with suitable tariffs from UK business energy suppliers. We’ll ask for the essentials to price accurately and explain any assumptions.
What you’ll need
- Business postcode
- Company details
- Recent bill (helpful, not essential)
What we check
- Meter type and consumption band
- Contract end date (if known)
- Unit rate + standing charge structure
Tip: If you can, locate your MPRN (Meter Point Reference Number) on a bill. It helps suppliers identify the correct supply point and reduces the risk of misquoting.
How business gas prices are built up (simple breakdown)
Most business gas quotes combine wholesale costs with non-energy charges and supplier operating costs. You’ll usually see two headline figures:
- Unit rate (p/kWh)
- What you pay for each kilowatt-hour of gas used. Heavily influenced by wholesale markets, your usage band, and contract length.
- Standing charge (p/day)
- A fixed daily charge that typically covers metering, network and supplier costs. The standing charge can materially affect low-usage sites.
What else affects the “real” price you pay?
VAT and eligibility
Many businesses pay 20% VAT on energy, but some may qualify for 5% VAT (e.g. certain charities or small usage thresholds). Always confirm with your accountant and supplier.
All-inclusive vs pass-through
Some contracts bundle non-energy charges into the unit rate (all-inclusive). Others itemise and pass them through (variable). Ask which you’re being quoted so you can compare fairly.

If you’re close to renewal
Many businesses begin comparing 8–12 weeks before their contract end date. Leaving it late can mean fewer options or rolling onto more expensive out-of-contract rates (where applicable).
Compare business gas price options (what to choose and why)
The right contract depends on how predictable your usage is, how comfortable you are with price risk, and whether you need flexibility (e.g. site moves, short leases). Use this table to compare common options.
| Option | How pricing works | Pros | Watch-outs | Best for |
|---|---|---|---|---|
| Fixed (1–3 years) | Unit rate and standing charge typically fixed for the term. | Budget certainty; easier forecasting. | Early termination fees; may not benefit if prices fall. | Most SMEs with stable premises/usage. |
| Flexible / variable | Rates can change (often with notice), tracking market movement. | Shorter commitment; potential to switch sooner. | Less cost certainty; can rise in volatile markets. | Businesses needing flexibility (short leases, uncertain load). |
| All-inclusive | Non-energy charges bundled into the rate structure. | Simpler comparisons; fewer surprises if clearly defined. | Check what’s included; definitions vary by supplier/contract. | SMEs wanting simplicity and predictable invoicing. |
| Pass-through | Some charges are billed at cost and can vary over time. | Can be competitive for larger users; transparency (if well itemised). | Bills can fluctuate; requires closer review of terms. | Larger or multi-site users with procurement support. |
Decision checklist (quick, practical)
This usually suits you if…
- You know your renewal date and want to avoid out-of-contract rates
- Your premises are stable (no planned move mid-term)
- You can provide an estimate of annual usage (or a recent bill)
- You prefer budgeting certainty (fixed term) or planned flexibility (variable)
It may not suit you if…
- You can’t commit to a term and may need to exit early
- You’re unsure the meter is registered correctly (address/occupier issues)
- Your landlord controls the supply or you’re on a managed/billed service
- You need complex procurement (multi-site, high-volume, bespoke risk strategy)
Ask every supplier for the same thing: unit rate (p/kWh), standing charge (p/day), contract length, what’s included/excluded, payment method assumptions, and any exit fees. That’s the quickest way to compare fairly.
Two realistic cost scenarios (with assumptions)
These examples show how unit rate and standing charge translate into annual spend. They are illustrative only and exclude any site-specific adjustments. Your quote may differ.
Scenario A: small café (low/medium use)
- Annual use: 25,000 kWh
- Unit rate: 7.2p/kWh (estimated)
- Standing charge: 45p/day (estimated)
- VAT: 20% assumed
Estimated annual cost (ex VAT): (25,000 × £0.072) + (365 × £0.45) = £1,800 + £164.25 = £1,964.25
Estimated annual cost (inc 20% VAT): £2,357.10
Notes: A higher standing charge can disproportionately affect low-use sites; a lower unit rate isn’t always the cheapest overall.
Scenario B: small manufacturing unit (higher use)
- Annual use: 180,000 kWh
- Unit rate: 5.4p/kWh (estimated)
- Standing charge: 85p/day (estimated)
- VAT: 20% assumed
Estimated annual cost (ex VAT): (180,000 × £0.054) + (365 × £0.85) = £9,720 + £310.25 = £10,030.25
Estimated annual cost (inc 20% VAT): £12,036.30
Notes: Higher users can access different pricing bands; credit terms and pass-through charges can matter more at this scale.
Assumptions & limitations: These examples assume a single-site business, standard billing, no unusual meter costs, and stable consumption. They do not include any one-off fees, debt repayment plans, deposits, or bespoke network arrangements.
Extra costs, exclusions and common pitfalls
Comparing business gas prices is easiest when you know what can change the final bill. These are the most common areas that cause confusion.
Out-of-contract rates
If your fixed term ends and you don’t renew, you may roll onto variable/out-of-contract pricing (where offered), which can be higher and can change. Always confirm your end date.
Auto-renewal windows
Some business contracts have renewal clauses. Check notice periods and renewal terms early so you can compare quotes without rushing.
Termination/exit fees
Leaving a fixed contract early can trigger charges. If you may relocate or close, ask for the fee basis and any transfer options.
Estimated reads and billing accuracy
If your meter readings are estimated, bills can swing. Submitting regular reads (or ensuring smart/AMR where applicable) can reduce surprises.
Pass-through charge changes
With pass-through arrangements, parts of your bill can vary due to external charges. Ask which components are fixed and which can move during the term.
VAT rate assumptions
Quotes may show ex-VAT figures. Confirm whether you’re being shown ex-VAT or inc-VAT and what VAT rate is assumed for your organisation.
Quick sanity check before you sign: Are the supply address, MPRN, contract end date, rates (unit + standing), and payment method correct? Small admin errors can create big delays or misbilling.
Business gas prices FAQs
1) Why is my business gas price different from another business nearby?
Quotes can differ due to annual consumption (AQ), meter type, network region, payment method, credit assessment, and contract length. Even similar premises can sit in different usage bands or have different billing histories.
2) What’s the difference between unit rate and standing charge?
The unit rate is what you pay per kWh used. The standing charge is a daily fixed amount. Low-usage sites should pay close attention to the standing charge because it can make up a large share of the total bill.
3) Are business gas prices capped in the UK?
Ofgem’s energy price cap applies to domestic customers, not most business contracts. Business pricing is generally market-based and contract-led. If you’re a microbusiness, you may have extra protections, but not the domestic price cap.
4) What is an MPRN and do I need it to switch?
Your MPRN is the unique identifier for your gas supply point. You can often get quotes without it, but providing it helps suppliers confirm the correct meter and can reduce delays or quoting errors when you switch.
5) When should I start comparing business gas quotes?
A practical window is 8–12 weeks before renewal. This allows time to confirm meter details, resolve any address/occupier issues, and compare like-for-like terms (including any notice periods and renewal clauses).
6) Can I get business gas on a rolling or short contract?
Often yes, depending on supplier and eligibility. Flexible/variable options can suit short leases or uncertain usage, but they may offer less price certainty. Always confirm notice periods and how/when rates can change.
7) What happens if I move premises mid-contract?
Terms vary. Some suppliers may allow a contract transfer to a new site; others may charge termination fees. If a move is likely, raise it before signing and ask for the exact policy in writing.
8) Do I pay 5% or 20% VAT on business gas?
Many businesses pay 20%. Some organisations and situations may qualify for 5% VAT (for example, certain charities or specific usage conditions). Check GOV.UK guidance and confirm with your supplier/accountant.
Trust, methodology and sources
How we assess business gas pricing on this page
Our approach
- Explain pricing components businesses actually see on quotes (unit rate + standing charge).
- Highlight common contract structures (fixed, flexible, all-inclusive, pass-through).
- Use worked examples to show how rates translate into annual cost.
- Focus on decision factors that affect SMEs: renewal timing, meter identification, VAT assumptions, fees.
Limitations (what we can’t guarantee)
- We don’t publish a single “average price” because business quotes are highly site-specific.
- Rates move over time with wholesale markets and supplier risk appetite.
- Eligibility and credit checks can change the final offered rate or require a deposit.
- Some charges may be treated differently between suppliers/contracts (especially pass-through).
Editorial independence: This guide is written to help businesses understand pricing and compare contracts. Quotes are provided subject to supplier availability and terms. Always read the contract and confirm what’s included before agreeing.
