Business gas rates per unit (p/kWh) in the UK — what to expect today
There isn’t one single “today” unit rate for business gas in the UK. Your pence per kWh depends mainly on your annual usage, meter type (e.g., standard vs larger supply points), region, contract length, and credit/terms. The only reliable way to know your current unit rate is to compare quotes built from your meter details.
Unit rate is only half the story
You also pay a standing charge (p/day). Always compare the estimated annual cost, not just p/kWh.
Usage level drives pricing
Higher-consuming sites often access lower p/kWh, but may face more complex terms (e.g., tighter credit requirements).
Timing and contract length matter
Wholesale prices move daily. Longer deals can offer bill stability, but may cost more at times.
Quick tip: If you have your MPRN (gas meter point reference number) and a recent bill, you can get like-for-like quotes faster and avoid estimates being based on the wrong usage band.
Compare business gas unit rates with a like-for-like quote
Tell us a few details and we’ll compare business gas tariffs across the market (where available) and return quotes built around your meter and estimated usage. You’ll see the unit rate (p/kWh), standing charge and estimated annual cost so you can choose what suits your business.
What you’ll need (if possible)
- Postcode and business name
- Gas MPRN (from your bill)
- Annual kWh (or last 12 months’ spend)
- Contract end date (if known)
What we’ll show you
- Estimated unit rate (p/kWh) and standing charge (p/day)
- Contract length options (e.g., 1–3 years where available)
- Key terms to check (fees, billing, payment method)
- Next steps to switch (or renew) at the right time
Important: Business energy quotes can be subject to credit checks and supplier eligibility (for example, certain suppliers may not take on specific premises types or very low/high usage sites). Terms vary by supplier.
Request quotes
How business gas unit rates are set (and why they differ)
1) Your wholesale cost (market movement)
Suppliers buy gas ahead of time. The wholesale market changes daily, which feeds into the prices available when you request a quote.
2) Network charges (distribution & transportation)
Charges to move gas through the network vary by location and supply point characteristics, affecting both unit rate and standing charge.
3) Meter type and consumption band
A small café on a basic meter will often be priced differently to a large site with higher consumption and a different supply class. Suppliers price by usage bands.
4) Contract terms and risk
Longer fixed contracts can include a risk premium for the supplier. Credit terms, payment method and billing preferences can also change pricing.
Business vs domestic: Business energy is not governed by the same tariff rules as domestic energy. You may not have access to the same switching protections and price structures as households, and contract terms can be stricter.
Two realistic cost scenarios (with numbers)
These examples show how unit rate and standing charge combine. They are illustrative only and not a promise of availability. VAT treatment can vary by business circumstances; some supplies may qualify for reduced VAT. Always check your invoice and eligibility.
Scenario A: Small hospitality site
- Assumed annual usage
- 25,000 kWh
- Estimated unit rate
- 6.8p/kWh
- Estimated standing charge
- 32p/day
- Estimated annual cost (excl. VAT)
- £1,817
Calculation: (25,000 × £0.068) + (365 × £0.32) = £1,700 + £116.80 = £1,816.80.
Scenario B: Medium industrial/workshop site
- Assumed annual usage
- 220,000 kWh
- Estimated unit rate
- 5.2p/kWh
- Estimated standing charge
- 55p/day
- Estimated annual cost (excl. VAT)
- £11,642
Calculation: (220,000 × £0.052) + (365 × £0.55) = £11,440 + £200.75 = £11,640.75.
Why the higher user gets a lower p/kWh: suppliers often price more competitively for larger, steadier usage profiles. But the standing charge may be higher, and the contract terms may be less flexible.
Business gas rate comparison: what to compare (not just the unit rate)
Use the table below to compare quotes consistently. Aim to compare on total estimated annual cost and the key terms that affect risk and flexibility.
| Compare this | Why it matters | What to ask / check |
|---|---|---|
| Unit rate (p/kWh) | Directly affects cost per unit consumed. | Is it fixed for the full term? Any pass-through elements? |
| Standing charge (p/day) | Can dominate costs for low-usage sites. | Is it fixed? Are there separate metering/admin charges? |
| Estimated annual cost | Best single comparison metric when assumptions match. | What kWh assumption is used? Can it be updated from your bill? |
| Contract length | Affects price certainty and exit exposure. | What are the renewal/termination windows and end date? |
| Termination / exit fees | Can make switching mid-term costly. | Is there an early termination charge, and how is it calculated? |
| Billing & payment method | Some suppliers price differently for DD, paper bills, etc. | Direct Debit required? Any discounts or fees for invoicing options? |
Decision checklist: who comparison suits
- You’re within ~6 months of contract end (or on out-of-contract rates).
- You have a recent bill (or can estimate annual kWh realistically).
- You want clarity on total cost, not just the headline p/kWh.
- You’re comparing options for one site or multiple meters.
Who it may not suit (or needs extra care)
- You’re mid-contract with significant exit fees.
- Your premises are newly occupied with no usage history (quotes may be more estimated).
- You have complex supply arrangements (multiple sites, high demand, or specialist meters).
- Your business is in financial distress (supplier credit terms may limit availability).
Like-for-like rule: Always check the quote is built for the correct site/meter and that usage assumptions are similar across suppliers. A low assumed kWh can make a quote look cheap but understate your likely cost.
Costs, exclusions and common pitfalls (UK business gas)
Unit rate comparisons can go wrong when key costs or rules are missed. Here are the most common issues business owners run into, and how to avoid them.
Out-of-contract rates
If your contract ends and you don’t renew, you may move onto higher deemed/out-of-contract prices. Start comparing before your end date.
Auto-rollovers & notice windows
Some contracts have specific renewal notice periods. Missing them can limit options. Check your current supplier terms and dates.
Standing charge impact
Low-usage sites can pay a large share of their bill via the standing charge. A slightly higher unit rate can be cheaper overall if the standing charge is lower.
Wrong usage assumptions
Quotes built on estimated kWh may not reflect your true profile (seasonal businesses especially). Use a recent bill if you can.
VAT & eligibility
VAT and other invoiced items depend on your circumstances. Confirm how VAT is applied and whether reduced VAT applies to your business.
Broker/agent fees & commissions
Some arrangements include fees or commission within rates. Ask how quotes are remunerated and ensure pricing is transparent.
Practical safeguard: When reviewing any quote, request confirmation of: (1) unit rate p/kWh, (2) standing charge p/day, (3) contract start/end dates, (4) any exit/termination charges, and (5) the kWh used for the estimate.
FAQs: business gas rates per unit (UK)
What is a business gas “unit rate”?
It’s the price you pay for each unit of gas you use, usually shown as pence per kWh on your bill or quote. Your total bill also includes a standing charge (p/day) plus any other applicable charges and VAT.
Is there a price cap for business gas in the UK?
Generally, no. The Ofgem price cap applies to many domestic customers. Business gas pricing is usually contract-based and can vary widely by supplier, site and terms. Always compare like-for-like quotes.
Why do two businesses in the same town get different p/kWh?
Even nearby sites can differ by meter details, annual usage band, consumption pattern, contract length, payment method, and credit terms. Small differences in standing charge can also change the effective cost per kWh.
What’s more important: unit rate or standing charge?
It depends on your usage. For low-usage sites, the standing charge can be a large portion of the bill. For high-usage sites, small differences in p/kWh can add up quickly. Compare the estimated annual cost using realistic kWh.
When should I compare business gas contracts?
Many businesses start reviewing options several months before their contract end date. The best window depends on your supplier’s termination notice rules and market conditions. If you’re already out of contract, comparing sooner can help you avoid prolonged deemed rates.
Do smart meters change business gas pricing?
A smart meter doesn’t automatically mean a cheaper rate, but it can improve billing accuracy and provide better consumption data. Some suppliers may have preferences or eligibility criteria tied to meter type and data availability.
Can I switch business gas supplier if I’m in debt?
Possibly, but it can be more complicated. Some suppliers may require debts to be cleared or may decline based on credit checks. If you’re struggling, it’s worth getting advice and speaking with your supplier about payment options.
What information makes a quote more accurate?
Your MPRN, postcode, and a recent bill showing annual kWh (or at least recent consumption) help ensure the quote matches your actual supply details. Without this, quotes may rely on estimated usage bands and could be less representative.

How we assess “business gas rates per unit”
Because business gas pricing is quote-led and varies by site, this page avoids presenting a single “national rate” as fact. Instead, we focus on what drives unit rates, how to compare quotes fairly, and how to avoid common contract pitfalls.
- Comparisons are structured around: unit rate (p/kWh), standing charge (p/day), contract length, estimated annual cost, and key terms (exit fees, billing/payment).
- Example scenarios: we use simple arithmetic (kWh × unit rate + 365 × standing charge) to show how costs build up.
- Limitations: quotes can change daily; supplier appetite varies; credit checks and meter/supply class can affect availability; taxes and additional charges may apply depending on circumstances.
Reputable UK sources we reference
- Ofgem — energy market regulator information and guidance.
- Citizens Advice energy advice — practical consumer and small business-facing energy guidance.
- GOV.UK — official UK government information (including business support and regulatory updates when applicable).
