Fast answer: what is a flexible business energy tariff in the UK?
A flexible business energy tariff (often called a flexible contract or basket deal) is a business electricity and/or gas contract where your unit rate is linked—directly or indirectly—to wholesale market prices. Instead of locking everything in on day one like a fixed tariff, you typically buy energy in chunks over time (sometimes called hedging or tranching), aiming to reduce timing risk.
Flexible does not automatically mean cheaper. It means more choice over buying strategy—and more exposure to price movements—so suitability depends on usage, cashflow tolerance and how actively you want to manage procurement.
Key takeaways (for busy decision-makers)
- Most suitable for medium-to-high usage businesses, multi-site portfolios, and organisations that prefer risk-managed buying rather than a single fixed price.
- Least suitable for very small usage, short trading history, or anyone who needs total bill certainty month-to-month.
- Quotes depend on meter type (HH vs NHH), credit checks, region (DNO/gas LDZ), contract length and whether you want partial fixing or full flexibility.
- Always check: fees, volume tolerance, pass-through charges (e.g., DUoS/TNUoS) and what happens at contract end (out-of-contract rates can be high).
How flexible business energy contracts work (plain English)
A flexible contract typically separates your cost into parts. The biggest variable is the wholesale energy cost, which you can buy over time rather than fixing all at once.
- 1) Your forecast volume
- An estimate of how much electricity (kWh) and/or gas (kWh) you’ll use during the contract. Some contracts allow a tolerance (e.g., ±10%).
- 2) Wholesale purchasing (your “fixing” decisions)
- You might fix 0%, 25%, 50%… up to 100% of forecast volume at different times. What’s unfixed may float against market prices (structure varies by supplier).
- 3) Supplier costs and margin
- Includes supplier operating costs, customer service, risk costs and margin. Some suppliers show this clearly; others bundle it in.
- 4) Network and policy charges (often pass-through)
- Electricity: DUoS/TNUoS, meter operator/DC/DA charges (especially for HH). Gas: transportation charges. These can change during the year and vary by region and meter profile.
Important: Many flexible contracts are quoted as “wholesale + pass-through” or “fully flexible”. Ask whether charges are fixed for the term or passed through at cost, and how frequently they update.
Who flexible tariffs suit (and who they don’t)
Often a good fit if you…
- Use a lot of energy (or have multiple meters/sites)
- Have half-hourly (HH) electricity metering, or time-of-use exposure
- Can plan budgets with ranges (not exact unit rates)
- Want the option to fix in stages when markets move
Usually not ideal if you…
- Need a single fixed p/kWh for the whole term
- Have very low usage (admin costs can outweigh benefits)
- Don’t want to make (or delegate) buying decisions
- Could struggle with higher bills if markets rise
If you’re unsure, we can compare fixed and flexible side-by-side using your meter details and latest consumption.

Flexible vs fixed business energy: quick comparison
Use this to decide whether to compare flexible tariffs now or focus on fixed rates. Terms vary by supplier; this table is a practical guide rather than a promise of outcomes.
| Feature | Flexible tariff | Fixed tariff |
|---|---|---|
| Price certainty | Medium/low (varies by how much you fix) | High (unit rates fixed for term, subject to contract details) |
| Potential benefit | Ability to average-in purchases and manage timing risk | Budget stability and simpler administration |
| Admin & oversight | Higher (buying windows, reporting, risk approach) | Lower (single rate agreed upfront) |
| Typical fit | Medium/large usage, HH meters, multi-site, energy-intensive operations | Small/medium usage, single site, needs fixed budgets |
| Risk if prices rise | Higher exposure unless you’ve fixed enough volume | Lower (during the fixed term) |
| Pass-through charges | Common (network/policy charges may vary) | Sometimes bundled, sometimes pass-through (check) |
Decision checklist (printable)
Choose flexible if most are true:
- We can handle bills moving within a range
- We have strong usage data (or HH data) to forecast
- We’re willing to fix in stages (or appoint someone to)
- We want transparency on wholesale and pass-through charges
Choose fixed if most are true:
- We need predictable p/kWh for budgeting
- We don’t want ongoing procurement decisions
- Our usage is low/steady and simplicity matters most
- We’d rather avoid pass-through exposure where possible
If you’re on the fence:
- Ask for a blended approach (e.g., fix 50% now, 50% later)
- Compare all-in estimated costs, not just headline p/kWh
- Check volume tolerance and any management fees
Costs, exclusions and common pitfalls (UK-specific)
1) Pass-through charges can move
Many flexible deals pass through network and policy charges. These can change due to industry updates and may vary by DNO region, time bands and metering. Ask what’s fixed and what’s variable.
2) Volume risk and tolerance
If your forecast is wrong, you may face imbalance costs or tolerance charges (contract-dependent). Seasonal businesses should discuss expected variance upfront.
3) Fees and contract structure
Some suppliers add management fees, trading fees or bespoke terms for HH/multi-site. Ensure you understand how fees are charged and when they apply.
Two realistic scenarios (illustrative numbers)
These examples show directional outcomes, not a prediction. They use simplified assumptions to help you understand exposure.
Scenario A: small office (prefers certainty)
- Electricity use: 18,000 kWh/year (non-HH)
- Assumed all-in fixed rate: 26p/kWh + standing charge (ignored for simplicity)
- Estimated annual unit-cost spend: £4,680 (18,000 × £0.26)
If this business went flexible and wholesale rose during winter, the unit-cost spend could exceed the fixed estimate. For low usage, the extra admin and variability often outweigh the upside.
Scenario B: light manufacturing site (risk-managed buying)
- Electricity use: 420,000 kWh/year (often HH)
- Flexible approach: fix 60% of forecast at 20p/kWh, leave 40% floating
- Floating average over year (illustrative): 24p/kWh
- Blended unit-cost estimate: (0.6 × 20p) + (0.4 × 24p) = 21.6p/kWh
- Estimated annual unit-cost spend: £90,720 (420,000 × £0.216)
If markets fell, the floating portion could help. If markets spiked, fixing a higher percentage earlier could have reduced exposure. The key advantage is control over timing—not guaranteed savings.
Assumptions used above: unit-rate-only illustration; standing charges, CCL/VAT where applicable, and pass-through charges excluded; actual structures vary by supplier and meter profile.
Common exclusions to watch
- Out-of-contract rates (often materially higher)
- Deemed rates if a new occupier takes supply without a contract
- Early termination fees or “loss of bargain” charges
- Smart/HH data services and metering agent costs
- Credit requirements (deposits, direct debit, personal guarantee in some cases)
Tip: Ask for a clear breakdown of what’s included in the p/kWh and what is billed separately as pass-through.
FAQs: flexible business energy tariffs (UK)
Are flexible tariffs only for large businesses?
Not always, but they’re most common where usage is high enough to justify the extra complexity (often HH electricity or multi-meter portfolios). Smaller businesses can sometimes access flexible-style products, but many will prefer a fixed tariff for simplicity.
Do flexible contracts mean my bills change every day?
Not necessarily. Some flexible products settle monthly, some allow staged fixes, and some have elements that float with the market. The frequency depends on the contract structure and what proportion is fixed vs floating.
What’s the difference between flexible and “variable” business energy?
A typical variable or out-of-contract rate is set by the supplier and can change at their discretion (subject to contract terms). A flexible contract usually has a defined method for how wholesale purchasing works, with reporting and buying options—so you can actively manage exposure.
Can I switch to a flexible tariff if I have debt on my current account?
It depends. Some suppliers won’t accept a new contract until debt is cleared, and credit checks may affect eligibility. If you’re struggling, it may be better to speak to your current supplier first and seek independent guidance.
Do I need a smart meter or half-hourly meter?
Not always, but flexible procurement is often paired with HH electricity because it gives clearer usage data and time-of-day charging exposure. If you’re not HH, you can still compare—just expect fewer product options and different pricing structures.
What’s “pass-through” and why does it matter?
Pass-through means certain charges (often network/policy costs) are billed at cost as they change, rather than being bundled into a fixed unit rate. This can improve transparency, but it also means your all-in price can move during the contract.
When is the best time to compare flexible tariffs?
Start early. Many businesses can agree a new contract ahead of the end date, but notice periods and supplier timelines vary. Comparing in advance gives time to gather bill data, complete credit checks, and choose a buying strategy rather than rushing onto out-of-contract rates.
Will a flexible contract include both electricity and gas?
Some suppliers can quote combined packages, while others treat fuels separately. Availability depends on meter details (MPAN/MPRN), consumption levels and how the supplier structures its flexible products.
Trust, editorial standards and transparent methodology
How we assess flexible business energy tariffs
Our aim is to help UK business owners compare options without hype. When we discuss flexible tariffs, we focus on the factors that most affect real-world cost and suitability:
- Metering and data: HH vs non-HH, number of meters, data availability and settlement implications.
- Contract structure: fully flexible vs partially fixed, fixing windows, reporting, and governance (who makes buying decisions).
- Charges: what is bundled vs pass-through (network/policy), and how/when those components can change.
- Commercial terms: credit requirements, deposits, volume tolerance, early termination terms, rollover/out-of-contract provisions.
- Operational fit: internal capacity to manage procurement, risk appetite, and budget resilience.
Limitations: This guide is informational and not financial advice. Supplier policies, credit decisions, and industry charges change. We recommend confirming full terms in writing before agreeing a contract.
