Business gas unit rates today: the quick answer
There isn’t a single “UK business gas unit rate” that applies to every company. Today’s price you’ll be offered is usually made up of (1) a unit rate in p/kWh and (2) a daily standing charge, and it can vary sharply based on your meter type (e.g., smart, AMR/half-hourly), annual usage, location, payment terms and contract length.
Important: Unlike household energy, business energy prices are generally not price-capped. If you’re out of contract you may be on deemed (or other default) rates, which can be significantly higher than negotiated fixed contracts.
Key takeaways (what to do next)
- Check your contract status first: if you’re out of contract, prioritise getting back onto an agreed tariff.
- Compare like-for-like: unit rate, standing charge, contract length, payment method, renewal/termination terms and any broker fees.
- Have your basics ready: business postcode, MPRN (gas supply number) or a recent bill, estimated annual kWh, and contract end date.
- Don’t use “average rates” to sign: use them only as context, then get a tailored quote for your site(s).
Compare business gas unit rates for your site
If you want the rate that actually applies to you, the quickest route is a whole-of-market comparison based on your meter and usage profile. We’ll use the details you provide to request or calculate supplier offers where available.
What you’ll get: a clear view of unit rate (p/kWh), standing charge (p/day), contract length and key terms — so you can decide with confidence.
What affects business gas unit rates (UK-specific)
Meter type & read frequency
Smart/AMR and larger sites (including half-hourly where relevant) can price differently from small non-half-hourly (NHH) supplies.
Annual usage (kWh)
Higher, steadier consumption can mean better p/kWh, but standing charges and risk premiums still matter.
Contract length & start date
1, 2, 3+ year terms can price differently. Start date timing and market movements can change offers day-to-day.
Credit & payment method
Direct debit vs invoice, payment terms, and credit checks may affect whether suppliers quote and the rates offered.
Location & network costs
Costs vary by region and network charging structures, so two identical businesses can see different standing charges.
Out of contract / deemed rates
If you roll onto default rates, you’re often paying for supplier risk and lack of commitment—typically higher than fixed deals.
What to check on your bill (so comparisons are accurate)
- MPRN (Meter Point Reference Number)
- Your gas supply number used to identify your meter point. Helpful for pinpoint-accurate quotes.
- Annual consumption (kWh) or spend
- A recent 12-month figure is best. If you only know monthly spend, we can estimate—less precise.
- Contract end date & notice period
- Leaving it too late can trigger auto-rollover or narrower options, depending on your supplier and terms.
- Current unit rate + standing charge
- Needed for a true “is switching worth it?” comparison (p/kWh and p/day both matter).

Compare business gas unit rates: what you’re really choosing
The cheapest p/kWh isn’t always the best deal. The right option depends on your risk appetite, cash flow preferences, and how certain your usage is.
| Option | How pricing works | Best for | Watch-outs |
|---|---|---|---|
| Fixed contract (12–36 months) | Unit rate and standing charge are fixed for the agreed term (subject to terms, pass-throughs where applicable). | Most SMEs that want cost certainty and predictable bills. | Early exit fees, auto-rollover clauses, billing disputes if reads are wrong. Always confirm contract end date + notice period. |
| Variable / flexible | Rates can move with supplier pricing (and market costs), sometimes with shorter commitment. | Businesses that can tolerate price movement or expect usage/location changes soon. | Budget uncertainty; check how and when rates can change, and whether notice is provided. |
| Deemed / out-of-contract | Default rates when no formal contract is agreed (e.g., move-in, contract ended, or supplier default). | Short-term only while you arrange a proper tariff. | Often among the highest rates. Risk of paying more while you “wait for prices to fall”. |
Decision checklist (who it suits / who it doesn’t)
A fixed deal may suit you if…
- you want predictable costs for budgeting
- you’re staying in the premises for 12+ months
- you want to reduce the risk of mid-year price rises
- you can meet supplier payment terms (often direct debit)
A fixed deal may not suit you if…
- you may move premises or close sites soon
- your usage is highly uncertain (renovation, seasonal trade changes)
- you’re likely to need to exit early (potential fees)
- you need very flexible payment options
If you’re on deemed rates now…
Treat it as a stopgap. Your priority is usually to move onto an agreed tariff with clear terms.

Two realistic cost scenarios (with assumptions)
Scenario A: Small café (SME) on a 12‑month fixed
Assumptions: 30,000 kWh/year gas use; unit rate 6.2p/kWh; standing charge 32p/day; prices are ex VAT and exclude any additional contract-specific pass-throughs.
| Cost element | How it’s calculated | Estimated annual |
|---|---|---|
| Unit charges | 30,000 × £0.062 | £1,860 |
| Standing charge | 365 × £0.32 | £116.80 |
| Estimated total | Unit + standing | £1,976.80/year |
If your actual kWh differs, unit charges change proportionally. Standing charge stays roughly fixed.
Scenario B: Light industrial unit out of contract (deemed)
Assumptions: 120,000 kWh/year; deemed unit rate 9.8p/kWh; standing charge 70p/day; illustrative only — deemed rates vary by supplier and can change.
| Cost element | How it’s calculated | Estimated annual |
|---|---|---|
| Unit charges | 120,000 × £0.098 | £11,760 |
| Standing charge | 365 × £0.70 | £255.50 |
| Estimated total | Unit + standing | £12,015.50/year |
Why this matters: even if your unit rate drops by a few p/kWh on a fixed deal, at higher usage levels the difference can be material. However, always compare total cost and terms — not just the headline rate.
VAT reminder: business energy VAT is commonly 20%, but some organisations may qualify for reduced VAT (e.g., certain charities). Eligibility depends on your circumstances—check before signing.
Costs, exclusions and common pitfalls (so your quote matches your bill)
The quickest way to end up unhappy with a “good rate” is to compare quotes that aren’t like-for-like. Here are the most common issues we see for UK businesses.
1) Standing charge ignored
A low unit rate can be offset by a higher standing charge. Always review total annual cost using your kWh estimate.
2) Wrong consumption estimate
If your annual kWh is understated, the comparison can look artificially cheap. Using the last 12 months is best, accounting for seasonality.
3) Contract end date & notice period missed
Some contracts have notice windows. Missing them can mean fewer options or rolling onto default rates. Confirm dates in writing.
4) Exit fees and moving premises
If you move, you may need to transfer the contract, renegotiate, or pay termination charges—depending on the agreement.
5) Payment terms and credit checks
A quote may assume direct debit or specific invoice terms. If your business needs different terms, supplier options can change.
6) Read quality and billing accuracy
Estimated reads can cause catch-up bills later. Smart/AMR can help, but still check that meter details and reads are correct.
Practical check before you agree: ask for a written confirmation of the unit rate, standing charge, contract start/end dates, notice period, exit fees, and any additional charges. If anything is unclear, pause and query it.
Business gas unit rates UK: FAQs
Are business gas prices capped in the UK?
Generally, no. The domestic Ofgem price cap applies to household standard variable tariffs, not most business contracts. Business rates are typically set by suppliers based on wholesale markets, risk, and your supply details.
What’s the difference between a unit rate and a standing charge?
Unit rate is what you pay per kWh of gas used. Standing charge is a daily fixed cost to keep the supply active and cover network/metering and other fixed costs. Your total bill is usually both combined (plus VAT where applicable).
Why are the “rates today” different from what my neighbour business pays?
Even nearby premises can have different offers due to usage, meter setup, contract start date, payment terms, credit assessment, and supplier appetite for that type of risk. Comparing with your own bill details is more reliable than comparing with another business.
I’m out of contract — can I switch straight away?
Often, yes, but it depends on your current supplier’s deemed/default terms and any debt or site issues. If you’re out of contract, it’s usually sensible to arrange a formal tariff promptly and ensure your meter details and occupancy dates are correct.
Do I need my MPRN to get a business gas quote?
It helps a lot, especially for accuracy. Many suppliers can quote with postcode and business details, but MPRN + a recent bill reduces the risk of mismatched meter points and incorrect consumption assumptions.
Will switching interrupt my gas supply?
Normally, no. The physical gas supply remains the same; the billing supplier changes. Delays can happen if there are data issues (e.g., incorrect meter details) or disputes, so it’s worth checking your bill information is correct.
Can my business get a lower VAT rate on gas?
Some organisations may qualify for reduced VAT depending on usage and eligibility (for example, certain charities). This is fact-specific—check GOV.UK guidance or your accountant before assuming a lower rate.
What contract length is “best” for business gas?
There isn’t one best length. Shorter terms can give flexibility but may expose you to repricing sooner. Longer terms can provide stability but can be less forgiving if you move premises or your needs change. Compare 12, 24 and 36 months side-by-side on total cost and exit terms.
