Business gas contract rates (UK): fixed deals for 2026
A practical guide to how fixed business gas rates for 2026 are priced, what affects your quote, and how to lock in a contract with clear terms (standing charge, unit rate and end date).
- Understand what “fixed 2026” really means (and what it doesn’t)
- See typical cost drivers: meter type, usage band, region, credit checks and contract length
- Use our checklist and scenarios to decide whether to fix now or wait
Rates are estimated and supplier terms vary. Your final quote depends on your meter, usage, location, payment method and credit checks.
Fast answer: what are fixed business gas rates for 2026?
A fixed business gas contract for 2026 usually means your unit rate (p/kWh) and standing charge (p/day) are fixed for a set term that runs through some or all of 2026 (for example, a 12, 24 or 36-month deal starting now and ending in 2026). You pay for what you use, but the price per unit and daily charge won’t change during the contract—unless your contract includes pass-through charges or you breach terms.
What you can usually fix
- Unit rate (p/kWh)
- Standing charge (p/day)
- Contract end date
What may still vary
- VAT rate (5% for most; 20% for some uses)
- Consumption (your kWh changes your bill)
- Pass-through items (if included in contract)
Quick takeaways
- Quotes depend heavily on meter + usage band
- Exit fees can be significant—check before signing
- Start renewal early to avoid rolling rates

Compare fixed business gas contracts for 2026: what to choose
There isn’t one “best” fixed rate—quotes differ by business profile. Use the table to decide which contract shape fits your risk tolerance and cashflow needs.
| Option | Best for | Trade-offs | What to check in the contract |
|---|---|---|---|
| 12-month fixed | You want shorter commitment and to re-price sooner. | More frequent renewals; exposure to price rises at next renewal. | End date, auto-roll terms, notice window, exit fees. |
| 24-month fixed (ends in 2026) | Budgeting stability through 2026; you prefer fewer renewals. | Less flexibility if usage changes or you move site. | Change-of-tenancy rules, deemed rates, pass-through charges. |
| 36-month fixed | Long-term certainty; larger users with stable demand. | Higher risk of overpaying if market falls; higher exit fee risk. | Termination fees, credit terms, billing frequency, read types. |
| Flexible / variable | You need maximum flexibility or expect to change premises. | Budget uncertainty; rates can rise quickly. | How/when rates change, notice periods, any admin fees. |
Decision checklist: fixing into 2026 suits you if…
- You want predictable pricing for budgeting and tenders
- Your usage is stable and you expect to remain at the premises
- You’re approaching renewal and want to avoid rolling onto a deemed/out-of-contract rate
- You’re comfortable with a longer commitment and potential exit fees
It may not suit you if…
- You expect to relocate, close, or significantly change operating hours
- Your business is seasonal and cashflow is tight (standing charge still applies)
- You are unsure about tenancy / landlord responsibilities for the meter
- You need maximum flexibility to switch quickly if the market drops
Two realistic cost scenarios (with assumptions)
These examples are illustrative only. They show how unit rate + standing charge combine into an annual cost. They exclude any bespoke charges a supplier may apply, and assume consistent usage across the year.
Scenario A: Small café (single site, low usage)
- Annual usage (estimated)
- 12,000 kWh
- Fixed unit rate (illustrative)
- 7.2p/kWh
- Standing charge (illustrative)
- 55p/day
- Contract term
- 24 months (ending in 2026)
Estimated annual commodity cost: 12,000 × £0.072 = £864
Estimated annual standing charge: 365 × £0.55 = £200.75
Estimated annual total (ex VAT): £1,064.75
Why it matters: for lower usage sites, the standing charge can be a meaningful share of the annual cost.
Scenario B: Light industrial unit (higher usage)
- Annual usage (estimated)
- 120,000 kWh
- Fixed unit rate (illustrative)
- 6.1p/kWh
- Standing charge (illustrative)
- 95p/day
- Contract term
- 24 months (ending in 2026)
Estimated annual commodity cost: 120,000 × £0.061 = £7,320
Estimated annual standing charge: 365 × £0.95 = £346.75
Estimated annual total (ex VAT): £7,666.75
Why it matters: for higher usage sites, the unit rate tends to drive the bulk of the cost—small p/kWh differences can add up.
Costs, exclusions and common pitfalls (UK business gas)
Before you sign a fixed contract intended to run into 2026, these are the items that most often cause surprises. Use the cards to sense-check your quote and contract summary.
1) Deemed / out-of-contract rates
If your fixed deal ends and you don’t renew, you may move to a supplier’s deemed/out-of-contract rates, which can be higher and variable. Start comparing well before your end date.
2) Early exit / termination fees
Business contracts often include exit fees if you leave early, close the site, or switch outside agreed windows. Ask for the termination fee basis in writing.
3) Standing charges during shutdowns
Even if your gas usage drops to near zero (e.g., seasonal closure), you usually still pay a daily standing charge.
4) Estimated bills and read quality
Poor meter reads can lead to estimated billing and catch-up bills. If you don’t have smart reads, agree a clear read submission process and keep records.
5) Pass-through charges (contract-specific)
Some contracts fix the unit rate but allow certain charges to change. Always ask: “Is this fully fixed, or partially pass-through?”
6) Payment method & credit terms
Your quote can vary by payment method (e.g., direct debit vs BACS) and credit assessment. Some businesses may be asked for a deposit or shorter terms.
A quick pre-signing check (printable)
- Confirm the rates: unit rate (p/kWh) and standing charge (p/day), and whether VAT is included.
- Confirm the dates: contract start, contract end, and any cooling-off (if offered).
- Ask about pass-throughs: “Is any part variable and why?”
- Ask about exit fees: how calculated, when charged, and COT implications.
- Billing: frequency, read method (smart/actual/estimated), and what happens if reads are missed.
- Support: who to contact for meter issues, emergencies, and billing disputes.
FAQs: fixed business gas rates for 2026 (UK)
Can I fix my business gas “for 2026” now?
Often yes—by choosing a fixed term (commonly 24 or 36 months) that ends in 2026. Availability depends on supplier appetite, your meter type, usage band, and credit checks. Some suppliers also offer forward-start renewals that begin when your current contract ends.
What’s included in a fixed business gas rate?
Typically the unit rate and standing charge. However, contracts differ: some are “fully fixed”, while others allow certain charges to change (pass-through). Always ask for a written breakdown of what is fixed vs variable.
Why do two suppliers quote different rates for the same business?
Quotes vary by wholesale hedging approach, network area, your usage band (AQ/annual kWh), meter read quality, payment method, and credit assessment. Even small differences in assumptions (e.g., estimated consumption) can change pricing.
Do business gas contracts have a cooling-off period?
Cooling-off is not guaranteed for business-to-business contracts in the same way it is for domestic energy. Some suppliers may offer a short cancellation window, but it varies. Treat it as contract-specific and check the terms before you agree.
What happens if I move premises during a fixed contract?
This depends on the supplier and contract. You may be able to transfer the contract, you may need a new quote for the new site, or you may face termination fees. If a move is likely, raise it before signing and get the policy confirmed in writing.
Is a smart meter required for a fixed 2026 contract?
Usually not required, but smart/AMR reads can improve billing accuracy and reduce estimated bills. If you don’t have a smart meter, ask how often reads are needed and whether estimated billing affects your tariff or administration.
What details do I need to compare business gas rates properly?
At minimum: business postcode, current supplier, and an estimate of annual usage. For best accuracy: MPRN, meter serial number, AQ/annual kWh, and contract end date. A recent bill is ideal.
Are there Ofgem price caps for business gas?
The household price cap applies to domestic customers, not most business energy contracts. Business pricing is typically contract-based and risk-rated. That’s why comparing terms (especially exit fees and pass-through items) is important.
