Business fixed-rate energy contracts: the fast answer
A fixed-rate business energy contract typically locks your unit rate (p/kWh) and standing charge (p/day) for a set term (often 12, 24 or 36 months). You still pay more or less overall depending on how much energy you use, but the price per unit stays the same throughout the agreed term.
Best for
- Budget certainty (stable unit rates)
- Businesses that prefer predictable cashflow
- Sites with consistent opening hours and usage
Watch-outs
- Early exit/termination fees can apply
- Out-of-contract rates can be expensive
- Different pricing for HH meters and multi-site
What you’ll need
- Postcode + business details
- Meter numbers (MPAN for electric, MPRN for gas) if possible
- Estimated annual usage (kWh) or recent bills
Key takeaway: Comparing fixed contracts isn’t just “cheapest unit rate”. For many businesses, the biggest differences come from standing charge, contract length, payment terms, and termination/renewal clauses.
How fixed-rate business energy contracts work
A fixed-rate contract is agreed in advance with a supplier for a specific site (or group of sites). Your bill is usually built from:
- Unit rate (p/kWh)
- What you pay for each unit of energy used. For electricity this may be split by day/night if you have an Economy 7-style setup.
- Standing charge (p/day)
- A daily charge that applies regardless of usage. It can materially change the overall cost for low-usage sites.
- Contract term
- Commonly 12, 24, 36 months. Longer terms can improve certainty but may reduce flexibility.
- Payment method & credit terms
- Direct Debit, monthly/quarterly, or other terms. Suppliers may price differently based on credit assessment and payment profile.
UK-specific note: Business energy is regulated differently to domestic energy. Some protections apply to microbusinesses (based on size/consumption thresholds), but terms and dispute routes can differ from households.
When can you switch (and what to check first)?
- Renewal window: many contracts allow you to agree a new deal ahead of end date. Confirm your supplier’s notice period.
- Termination notice: leaving it too late can mean rolling onto out-of-contract rates or an auto-renewal clause (where applicable).
- Meter & site data: ensure the meter type and address match your bill to avoid delays.

Tell us a few details and we’ll match you with suitable fixed-rate options for your meter type and location. It takes about 2 minutes.
Tip: If you have them to hand, your MPAN/MPRN and latest bill help us confirm meter type (e.g., half-hourly) and reduce the risk of mismatched quotes.
Compare fixed-rate contract options (what to look at)
Below is a practical comparison framework you can use on any supplier quote. Exact names vary by supplier, but the cost drivers and terms are consistent across the UK market.
| What you’re comparing | Why it matters | What to ask / check | Who it most affects |
|---|---|---|---|
| Unit rate (p/kWh) | Primary driver of cost for high-usage sites. | Is it single-rate, day/night, or HH? Any time-of-use splits? | Manufacturing, hospitality, larger offices |
| Standing charge (p/day) | Can outweigh unit rate for low usage or seasonal sites. | Is it per meter? Does it change during the term? | Small offices, salons, storage units |
| Contract length | Longer terms can reduce admin and price volatility, but reduce flexibility. | Any break clauses? What happens at end of term? | All businesses |
| Termination / exit fees | Can be significant if you move premises or change needs. | How is it calculated: fixed fee, per remaining month, or usage-based? | Growing firms, businesses with leases ending |
| Billing & payment terms | Affects cashflow and may affect pricing/acceptance. | Monthly/quarterly? Direct Debit? Paperless billing? Late payment charges? | SMEs with tight cashflow |
| Meter type & data quality | Wrong meter data can lead to re-quotes or delayed switching. | Confirm MPAN/MPRN, profile class, and whether it’s half-hourly. | HH sites, multi-site, complex supplies |
Decision checklist: who a fixed rate suits
- You want predictable unit rates for budgeting
- You expect to stay at the same premises for the term
- Your usage is reasonably stable (or you can estimate it)
- You’re willing to commit to a term to reduce admin and rate volatility
Who it may not suit (or needs extra care)
- You may move site or close a location soon (exit fees risk)
- Your usage is highly seasonal or unpredictable
- You’re unsure of meter setup (e.g., half-hourly) and need specialist pricing
- You’re currently on a contract with a strict termination notice period
Two realistic scenarios (with numbers)
These examples show how standing charges and unit rates combine. They’re illustrative only (not a forecast) and exclude VAT. Actual quotes depend on your meter type, consumption shape, credit terms and supplier availability.
Scenario A: Small office (electricity only)
- Assumed annual usage: 12,000 kWh
- Contract: 24 months fixed
- Unit rate (estimated): 26.0p/kWh
- Standing charge (estimated): 55p/day
Estimated annual cost:
Usage: 12,000 × £0.26 = £3,120
Standing charge: 365 × £0.55 = £200.75
Total (ex VAT): £3,320.75
What changes the result most: if usage drops, the standing charge becomes a bigger share of the bill.
Scenario B: Café with electricity + gas
- Assumed annual usage: 30,000 kWh electricity + 60,000 kWh gas
- Contract: 12 months fixed
- Electric unit rate (estimated): 28.0p/kWh; standing: 65p/day
- Gas unit rate (estimated): 7.5p/kWh; standing: 35p/day
Estimated annual cost:
Electricity: (30,000 × £0.28) + (365 × £0.65) = £8,637.25
Gas: (60,000 × £0.075) + (365 × £0.35) = £4,627.75
Total (ex VAT): £13,265.00
What changes the result most: usage pattern, operating hours, and whether the electricity meter is half-hourly (which can be priced differently).
VAT reminder: Business energy is commonly charged at 20% VAT, but some organisations may be eligible for reduced VAT or exemptions (depending on use and status). Check your invoices or ask your accountant if unsure.
Costs, exclusions and common pitfalls (UK)
Fixed-rate contracts can be straightforward, but many “surprises” come from terms rather than the headline rate. Use these checks before agreeing a deal.
Out-of-contract rates
If your contract ends and you don’t renew or switch, you may move onto a deemed or out-of-contract rate that can be higher than fixed deals.
What to do: diarise your end date and any notice window. Start comparing in advance, especially for multi-site or HH meters.
Termination and move-out fees
Leaving early (including moving premises) can trigger charges. The calculation method varies by supplier and contract.
Ask: “If I move address or close the business, what fees apply and how are they calculated?”
Meter type mismatches
Quotes can change if your meter is half-hourly or if the recorded profile/class doesn’t match expectations.
What to do: provide MPAN/MPRN and a recent bill if you can; confirm if your electricity is HH settled.
Other charges and exclusions to be aware of
- VAT: often 20% (eligibility for reduced rates varies)
- Pass-through items: some contracts include charges that can change (ask if anything is pass-through)
- Billing fees: paper billing or late payment charges may apply
- Contract start date: may be subject to cooling/objection processes and industry timelines
Quick “pre-contract” questions to ask any supplier
- Are unit rates and standing charges fixed for the full term?
- What are the termination fees and how are they calculated?
- What happens at end of term if we don’t renew?
- Is the quote based on my correct meter type (single-rate, E7, HH) and address?
- What are the payment terms (Direct Debit, billing frequency, credit checks)?
Important: If you think you qualify as a microbusiness, you may have additional protections. If you’re not sure, it’s worth checking eligibility and asking the supplier how they treat microbusiness customers under their terms.
Business fixed-rate energy FAQs
Are business fixed-rate contracts the same as domestic fixed tariffs?
No. Business contracts often have different terms, renewal rules, and fee structures. Some consumer-style protections don’t apply in the same way, though microbusinesses can have extra protections compared with larger firms.
What contract length should I choose: 12, 24 or 36 months?
It depends on your priorities. Shorter terms can offer flexibility; longer terms can improve budgeting certainty and reduce renewal admin. Compare total cost (unit rate + standing charge) and pay close attention to termination fees if you might move premises.
Can I get a fixed rate with a half-hourly (HH) electricity meter?
Often yes, but pricing is typically more tailored to your consumption pattern (when you use energy) and may require more detailed data. If you suspect you’re HH, share your MPAN and a recent bill so quotes are based on the correct setup.
Do fixed rates mean my bill won’t change?
Your rates are fixed, but your bill can still change if your usage changes. For example, longer opening hours, new equipment, or seasonal demand will affect total cost.
What information do I need to compare fixed-rate business energy accurately?
Ideally: your business postcode, current supplier, contract end date, estimated annual kWh, and meter IDs (electricity MPAN and/or gas MPRN). A recent bill helps confirm meter type and current charges.
Is it cheaper to take electricity and gas with the same supplier?
Sometimes it can be simpler administratively, but it’s not automatically cheaper. Compare each fuel on its own merits (unit rates, standing charges, terms) and consider whether you want one renewal date or separate agreements.
What happens if I sign a contract and then realise the details were wrong?
If key details (like meter type, address, or consumption assumptions) are incorrect, the supplier may re-quote or the switch may be delayed. To reduce this risk, confirm MPAN/MPRN and provide a bill where possible before finalising.
How long does a business energy switch take in the UK?
Timescales vary by supplier, meter type, and whether there are objections or data issues. Many switches are completed within a few weeks, but complex meters or multi-site arrangements can take longer.
If you’re in a hurry: we can still help if your renewal date is close, but your current contract terms and notice period will determine what’s possible.

How we assess fixed-rate contract comparisons
Our comparison guidance and examples focus on the factors that most often change real-world outcomes for UK businesses:
- Total cost drivers: unit rates + standing charges over a year
- Contract risk: termination fees, end-of-term outcomes, notice periods
- Eligibility and pricing conditions: meter type (including HH), region, payment terms, and credit checks
- Data quality: whether the quote matches MPAN/MPRN, meter configuration, and usage assumptions
Limitations: the scenarios on this page use simplified assumptions and don’t represent every pass-through charge, site-specific agreement, or supplier policy. Your final rates can differ based on your consumption profile and supplier underwriting.
