Estimates for UK business customers. Final prices depend on your meter, usage, location, payment and credit profile, and supplier terms.

Fast answer: what are business gas rates per unit in the UK in 2026?

In 2026, business gas prices are quoted in pence per kWh (p/kWh) plus a separate daily standing charge. There isn’t one “UK rate” because suppliers price by risk and cost to serve—your meter type (MPRN class), annual usage, location, contract length, payment method and credit checks all influence what you’re offered.

Typical quote structure

Unit rate: p/kWh (what you pay for gas used)
Standing charge: p/day (fixed daily cost)
Contract term: commonly 1–3 years (variable options exist)

Where “per unit” trips people up

Two quotes can have the same p/kWh but different standing charges
VAT is often shown separately (most pay 20%; some may qualify for 5%)
Deemed/out-of-contract rates can be much higher than fixed deals

Best next step

To get a price you can rely on, compare using your usage (kWh) or last 12 months of bills.

Key takeaway: “Business gas rates per unit” only tells part of the story. To compare fairly, look at total estimated annual cost (unit rate × expected kWh + standing charges), then check contract terms and exit fees.

Compare business gas unit rates (and the full cost)

Tell us the basics and we’ll source estimated business gas quotes from across the market. We’ll show you the unit rate (p/kWh), standing charge, and key terms so you can compare like-for-like.

What you’ll need: business postcode and contact details. For best accuracy, have a recent bill to hand (MPRN and annual kWh).

What affects your 2026 unit rate?

Annual consumption (kWh): higher usage can access different bands and pricing
Meter type: standard vs AMR/SMART; larger sites may have larger capacity arrangements
Credit profile: some suppliers price higher or require deposits for higher-risk accounts
Contract length: longer terms can reduce exposure to short-term wholesale swings (not guaranteed cheaper)
Site details: location/network charges and admin costs vary

How business gas unit rates are priced (and how to compare properly)

1) Unit rate (p/kWh)

This is the price for each kilowatt hour you use. If you use 10,000 kWh and your unit rate is 6.0p/kWh, your usage cost is £600 (before VAT and standing charges).

2) Standing charge (p/day)

A daily fixed cost that covers things like keeping you connected and administration. Over a year, 70p/day is about £255.50 (70p × 365).

3) Contract type and term

Fixed: unit rate/standing charge fixed for the term (supply costs still regulated by contract terms)
Variable/flexible: can change, sometimes linked to a supplier’s tariff or wholesale movements
Deemed/out-of-contract: default rate if you move premises or a contract ends without renewal

4) VAT and CCL (Carbon Price Support / Climate-related charges)

Many business bills show VAT separately. Most non-domestic supplies are charged 20% VAT, but some businesses may qualify for reduced 5% VAT depending on use and eligibility.

Other line items can apply depending on your supply and billing setup. Always compare using the supplier’s estimated annual cost for your kWh.

Like-for-like rule: When comparing 2026 business gas quotes, ask for the same contract term, same start date assumption, and ensure the quote clearly states unit rate, standing charge, VAT, and any broker/third-party fees (if applicable).

Two realistic cost scenarios (with numbers)

Scenario A: Small café

Assumptions: Annual use: 12,000 kWh • Contract: 24 months fixed • Unit rate: 6.5p/kWh • Standing charge: 65p/day • VAT excluded
Estimated annual usage cost: 12,000 × £0.065 = £780.00
Estimated annual standing charge: £0.65 × 365 = £237.25
Estimated annual total (ex VAT): £780.00 + £237.25 = £1,017.25

Illustrative only. Your quote may differ based on location, meter details, payment method and supplier checks.

Scenario B: Light industrial unit

Assumptions: Annual use: 80,000 kWh • Contract: 36 months fixed • Unit rate: 5.1p/kWh • Standing charge: 95p/day • VAT excluded
Estimated annual usage cost: 80,000 × £0.051 = £4,080.00
Estimated annual standing charge: £0.95 × 365 = £346.75
Estimated annual total (ex VAT): £4,080.00 + £346.75 = £4,426.75

A lower p/kWh doesn’t always mean the cheapest overall—standing charges and terms can change the total.

Comparison: how unit rate and standing charge change the annual cost

Below is a simple illustration using the same annual gas use to show why “business gas rates per unit” should be compared alongside standing charges.

Illustrative quote	Unit rate (p/kWh)	Standing charge (p/day)	Assumed annual use	Estimated annual total (ex VAT)	Best for
Quote 1: Lower unit rate	5.6p	95p	25,000 kWh	(25,000×0.056)+ (0.95×365)= £1,746.75	Higher-use sites
Quote 2: Lower standing charge	6.1p	55p	25,000 kWh	(25,000×0.061)+ (0.55×365)= £1,726.75	Lower-use sites
Quote 3: Balanced	5.9p	70p	25,000 kWh	(25,000×0.059)+ (0.70×365)= £1,730.50	Most SMEs

What this table shows: Quote 2 has a higher p/kWh but is cheaper overall at 25,000 kWh because the standing charge is lower. If your usage is much higher, Quote 1 may win. That’s why we compare quotes using your kWh.

Decision checklist: who it suits / who it doesn’t

This approach suits you if…

You can share a recent bill (or annual kWh)
You want clarity on standing charges and terms
You’re within renewal window or moving premises
You have multiple sites and want consistent reporting

It may not suit you if…

You need a complex flexible procurement strategy (large users)
Your site has unresolved meter issues or disputed bills
You’re not authorised to agree a supply contract

Before you compare: gather these details

MPRN (gas meter point reference number)
Business name and supply address
Current supplier and contract end date (if known)
Annual consumption (kWh) or last 12 months bills
Meter type (smart/AMR) and any known site constraints

If you don’t have the above, you can still start—just expect follow-up questions to confirm pricing.

Costs, exclusions and common pitfalls (UK business gas)

Most complaints about “rates” come down to hidden assumptions. These are the points to check before you accept a 2026 contract.

1) Standing charges vary widely

A low p/kWh can be offset by a high daily charge. Always compare the estimated annual total for your kWh, not unit rate alone.

2) VAT assumptions

Quotes may show prices excluding VAT. Most businesses pay 20%. Some may qualify for reduced VAT depending on usage and eligibility—confirm with your accountant/supplier.

3) Deemed/out-of-contract rates

If you move in or your deal ends without renewal, you may be placed on a deemed rate. These are often significantly higher and can include stricter terms.

4) Auto-renewal and notice periods

Business contracts can have renewal windows and notice requirements. Missing a deadline can limit options or put you on less favourable rates. Check the end date and notice terms in writing.

5) Exit fees and contract flexibility

Fixed contracts commonly include early termination fees. If you may relocate, expand, or close a site, ask how moves and meter changes are handled.

Important: If a quote is presented as “all-inclusive”, ask what’s included (VAT? standing charge? any admin/broker fees?) and request the full tariff details in writing before you agree.

FAQs: business gas rates per unit (UK, 2026)

1) What does “per unit” mean for business gas?

It means the unit rate in pence per kWh. Your bill is usually (kWh used × unit rate) plus a daily standing charge, then VAT and any applicable line items.

2) Is there a price cap for business gas in 2026?

Ofgem’s price cap applies to domestic customers, not most business energy contracts. Business prices are typically contract-based and can vary by supplier and risk assessment.

3) Why did my unit rate increase even though wholesale prices fell?

Quotes reflect more than wholesale gas: network costs, supplier operating costs, risk buffers, contract start date, and your credit profile can all affect pricing. Also check whether the comparison includes the same standing charge and VAT assumptions.

4) How do I find my business gas usage in kWh?

Your bill usually shows consumption in kWh. If your meter reads in cubic metres (m³), your supplier converts it to kWh using an industry formula (volume correction and calorific value). For quoting, the easiest route is to provide a recent bill or your annual kWh figure.

5) What’s an MPRN and do I need it for a quote?

An MPRN (Meter Point Reference Number) identifies your gas supply point. It helps suppliers price accurately and avoid mismatches. You can often start without it, but having it speeds up quoting and reduces errors.

6) Can I switch business gas supplier if I’m in contract?

Usually you can, but early termination fees may apply on fixed contracts. If you’re unsure, check your current terms before initiating a switch or request an end date/renewal window from your supplier.

7) I’m moving premises—what happens to my gas rates?

If you move in and don’t set up a contract, you may be placed on a deemed tariff. It’s sensible to arrange supply early and confirm whether your existing contract can move with you (terms vary).

8) Are direct debit rates cheaper for business gas?

Sometimes. Some suppliers offer better pricing or smoother credit terms with direct debit, but it’s not universal. Compare the full quote and the payment terms (including deposits or billing frequency).

How we assess business gas “rates per unit” for 2026

This page is an editorial guide designed to help you compare quotes fairly, not a promise of specific pricing. Because business energy is priced per account, we focus on quote structure and comparison method.

Like-for-like comparisons: we recommend comparing on the same contract length and start-date assumption
Total cost focus: we show why unit rate + standing charge is the meaningful comparison
Scenario maths: example totals use the formula: (annual kWh × £/kWh) + (standing charge × 365)
Limitations: supplier appetite, credit checks, meter classes and regional/network cost differences mean actual quotes can vary materially

Editorial caveat: We avoid publishing a single “average 2026 p/kWh” because it can mislead businesses with different usage bands and standing charges. The best indicator is a written quote for your meter and consumption.
