Business gas rates per unit (UK): the fast answer
There isn’t a single “UK business gas unit rate today” that applies to everyone. Business gas is priced per meter point, and your unit rate (p/kWh) is usually built from wholesale gas costs plus supplier risk, operating costs and margin—then shaped by your usage pattern, location and contract terms.
Quick takeaway: treat “today’s business gas p/kWh” as a range. The only reliable way to know your current market rate is to request quotes for your meter, postcode and annual kWh (or a recent bill).
Key takeaways (unit rates)
- Unit rate (p/kWh) is what you pay for each kWh of gas used.
- Standing charge is daily (or monthly) and can materially affect low-use sites.
- Contract length typically changes the price (and risk) you’re locking in.
- Meter type (smart, traditional, U16, etc.) affects how suppliers quote.
What to have ready
- MPRN (gas meter point reference number) or a recent bill
- Estimated annual usage (kWh) if available
- Postcode and business name (for supplier checks)
- Current end date (to avoid out-of-contract rates)
When “today” matters most
- If your contract ends within the next 60–120 days
- If you’re on a deemed/out-of-contract tariff
- If you’ve moved premises and inherited supply
- If your usage has changed (e.g., heating upgrades or expansion)
Get tailored business gas unit rates (p/kWh) for your meter
If you want a figure you can actually act on, we’ll compare business gas deals across the market and return meter-specific quotes (unit rate + standing charge) based on your details.
What you’ll get: a set of estimated contract options (e.g., 12/24/36 months) with the p/kWh, standing charge and key terms—so you can compare like-for-like.
What affects your business gas unit rate today
Usage band & load profile: higher annual kWh can attract different pricing, but low usage can be heavily influenced by standing charge.
Region & network costs: where your site is (postcode) can change distribution and pass-through elements.
Contract length & start date: longer fixes reduce short-term exposure but can price in more supplier risk.
Credit & payment type: some suppliers price differently for direct debit vs other payment arrangements, and may require checks.
Request business gas quotes
Tell us where the meter is and how to contact you. If you don’t know your annual usage yet, we can still start with your postcode.
Already out of contract? You may be on a deemed rate set by your current supplier (often higher and changeable). Getting quotes early can help you regain cost certainty.
How business gas pricing works (so you can compare properly)
1) Unit rate (p/kWh)
The price of each unit of gas you consume. A low unit rate can look attractive, but always check the standing charge and any pass-through items included in the contract.
2) Standing charge (p/day)
A fixed daily cost to keep the supply active. For low-use businesses (small offices, seasonal sites), standing charge can dominate the annual cost.
3) Contract structure & pass-throughs
Some contracts are “fully fixed” (more bundled) while others pass certain charges through as they change. Ask what’s included so you’re not comparing apples with oranges.
Editor’s caveat: suppliers can use different naming for inclusions/exclusions. When you get quotes, ask for a one-page summary of what’s included, the contract end date, and any early termination or rollover terms.
Two realistic cost scenarios (with stated assumptions)
Scenario A: Small office / light heating load
- Assumed annual gas use
- 20,000 kWh
- Assumed unit rate
- 7.5p/kWh (estimated)
- Assumed standing charge
- 35p/day (estimated)
- Estimated annual energy cost
- (20,000 × £0.075) + (365 × £0.35) = £1,627.75/year
This example excludes VAT and any non-energy charges that may apply. Actual quotes can be higher or lower.
Scenario B: Restaurant / higher usage site
- Assumed annual gas use
- 120,000 kWh
- Assumed unit rate
- 6.3p/kWh (estimated)
- Assumed standing charge
- 55p/day (estimated)
- Estimated annual energy cost
- (120,000 × £0.063) + (365 × £0.55) = £7,761.75/year
Higher-use sites can see a lower p/kWh, but the “best” deal still depends on standing charge and contract terms.
Compare business gas options (what changes the unit rate)
Use this table to compare contract choices in a way that reflects how suppliers typically price risk and admin. Individual supplier rules differ, but the decision points below are consistent across most UK business gas quoting.
| Option | Best for | Trade-offs | What to check in the quote |
|---|---|---|---|
| 12-month fixed | Businesses wanting a shorter commitment and quicker re-price. | More exposure to renewal timing and market changes. | Unit rate + standing charge; renewal/rollover terms; exit fees. |
| 24–36 month fixed | Sites prioritising budgeting certainty over multiple winters. | Longer commitment; early termination can be costly. | Termination charges calculation; change-of-tenancy clauses. |
| Fully fixed vs pass-through | Fully fixed: simplicity. Pass-through: transparency for certain items. | Pass-through bills can vary even if headline p/kWh looks low. | Which charges are bundled; examples of pass-through items. |
| Single-site vs multi-site | Multi-site portfolios seeking consolidated billing and procurement. | Complexity: different meters, dates, consumption patterns. | Aligned start dates; billing format; site-by-site pricing breakdown. |
Decision checklist: who comparing unit rates suits (and who it doesn’t)
This approach suits you if…
- You can share a recent bill or your MPRN to quote accurately
- You want clear budgeting and an agreed contract end date
- You’re within renewal window (often 1–6 months ahead)
- You want to compare unit rate and standing charge, not just headlines
Be cautious / get advice first if…
- You’re in a complex tenancy situation (landlord controls the supply)
- Your meter setup is unusual or you suspect incorrect reads
- You plan to move premises during the contract term
- You’re in arrears—some suppliers may decline or require different terms
Costs, exclusions and common pitfalls (UK business gas)
If you’re focused on “business gas rates per unit today”, these are the items most likely to explain why your quote looks different to an advertised figure or another business’s deal.
Standing charge impact
Two quotes can have similar p/kWh but very different annual cost if one has a higher standing charge—especially for low consumption.
VAT treatment
Many small businesses are charged 5% VAT on energy, but some may be charged 20% depending on eligibility. Always confirm what the quote includes.
Deemed / out-of-contract rates
If you don’t agree a contract, your supplier can place you on a deemed tariff. Unit rates here are often higher and can change—check your welcome letter or bill.
Auto-rollover clauses
Some contracts can roll into a new term or a different rate if you miss the notice window. Put renewal dates in your diary and ask for notice rules.
Early termination charges
Exiting early can be expensive. If you might move premises, ask about change-of-occupancy terms and whether the contract can be assigned or moved.
Meter accuracy & reads
Estimated reads can distort billing. If you suspect a problem, provide up-to-date reads and ask about smart meter options where available.
Tip for comparing quotes: ask each supplier to show annual cost based on the same assumed kWh (your last 12 months if possible). Then sanity-check by calculating: (kWh × unit rate) + (365 × standing charge).
Business gas rates per unit UK: FAQs
What is a “unit rate” for business gas?
It’s the price you pay per kilowatt-hour (kWh) of gas used, usually shown in pence per kWh (p/kWh). Your bill is typically your unit rate cost plus a standing charge, and may also include VAT and other items depending on contract type.
Why can’t you show one “business gas rate today” for everyone?
Because supplier pricing is meter-specific. Quotes can differ by postcode, annual usage band, contract length, start date, payment method, and supplier credit requirements. “Today’s rate” is best treated as a market snapshot, not a guaranteed price.
What’s the difference between business and domestic gas prices?
Business energy contracts are generally negotiated/quoted rather than being standardised like many domestic tariffs. Consumer protections differ, and business contracts often include stricter termination terms. If you’re a microbusiness, you may have additional protections—confirm your status when you compare.
What is a deemed contract and why is it expensive?
A deemed contract can apply when a business moves into premises and uses energy without agreeing a new contract, or when a fixed contract ends. Deemed rates can be higher and may change—check your supplier documentation and consider agreeing a fixed deal if it suits your needs.
Do business gas quotes include VAT?
Not always. Some quotes show ex-VAT pricing; others show inc-VAT. Many eligible businesses pay 5% VAT on energy, but some situations attract 20%. Always ask “Is this unit rate inc or ex VAT?” before you compare.
When should I start comparing business gas rates?
Often, businesses start 1–6 months before the contract end date (supplier rules vary). Starting earlier can give you time to validate meter details, compare terms, and avoid rolling onto out-of-contract rates.
What information do suppliers need to quote accurately?
Typically your MPRN (or a recent bill), site postcode, business name, and estimated annual usage (kWh). Some suppliers will also consider payment method and may run credit checks for certain contract types.
Can I switch business gas supplier if I rent my premises?
Often yes, if you’re responsible for the energy bills and the meter is in your business’s name. If your landlord controls the supply or you’re sub-metered, you may not be able to choose the supplier—check your lease and current billing arrangements.

How we assess business gas unit rates (methodology)
- People-first focus: we explain what drives p/kWh and how to compare quotes, rather than publishing a single number that could mislead.
- Assumptions in examples: the scenario calculations use stated annual kWh plus estimated p/kWh and standing charge to show how bills are formed.
- What we do not do: we do not promise savings, and we do not present supplier-specific pricing as universal.
- Limitations: supplier appetite changes daily; prices differ by meter class, credit position, consumption profile, contract start date, and whether charges are bundled or pass-through.
- Like-for-like rule: we recommend comparing total annual cost using the same kWh assumption, and verifying VAT and termination terms.
Transparency note: business energy quotes can be time-limited and may change after supplier validation (meter details, credit checks, start date). Always request written confirmation of rates and terms before agreeing.
