What “cheapest fixed business energy rates” means this winter
In business energy, there isn’t a single national “cheapest fixed rate”. Suppliers price per meter and risk profile, and winter pricing can move fast. The aim is to secure the best-value total cost for your business—typically a combination of:
Unit rate (p/kWh)
The price you pay per kilowatt-hour. Winter “cheap” quotes often focus here—especially for high-usage sites like manufacturing, hospitality and retail.
Standing charge (p/day)
The daily cost to keep your site connected. For lower-usage sites (offices, small studios), the standing charge can be the difference between “cheap” and “not actually cheap”.
A fixed business energy contract usually locks in the unit rate and standing charge for an agreed term (commonly 12, 24 or 36 months). That stability can be particularly useful in winter when demand, wholesale costs and market sentiment can affect pricing.
Good to know: “Fixed” doesn’t mean your bill is the same each month. Your bill still changes with usage; the rate you pay per kWh stays the same.
Why fix your business energy rates before or during winter?
Fixed tariffs can suit many UK businesses when you want predictable costs through a high-demand season. Here are the practical reasons companies lock in rates.
Budget certainty
Protect your p/kWh from short-term market movement and plan cashflow for heating, lighting and peak trading months.
Avoid pricey rollover/deemed rates
If you let a contract end without renewing, you can land on higher default rates. Switching to a fixed deal can reduce that risk.
Better quote access
Suppliers may price differently by sector, region and usage. Whole-of-market comparison helps you find competitive quotes you might not see directly.
Support for multi-site businesses
Fixing rates across multiple meters can simplify forecasting and reduce admin, especially if renewals fall in different months.
Control over contract length
Choose a term that fits your plan—shorter for flexibility, longer to lock certainty (subject to supplier pricing and credit checks).
Cleaner procurement trail
Comparing rates and capturing quotes can help with internal approvals—useful for finance teams and facilities managers.
Not sure if fixed is right? If your usage is highly seasonal or you expect to relocate, tell us when you request quotes. We’ll explain the trade-offs and any exit fees before you choose.
How to compare fixed business energy rates (and actually get the cheapest deal)
Comparing business energy isn’t like domestic switching. Prices are tailored, and the cheapest deal is the one that best fits your meter, pattern of use and contract terms. Use this checklist to compare quotes properly.
1) Confirm your meter and tariff type
Are you on a standard meter, smart meter, or half-hourly (HH) profile? HH and larger sites can have additional elements that affect pricing.
2) Compare total cost, not just the headline p/kWh
A slightly higher unit rate can still be cheaper overall if the standing charge is lower (or if your consumption is modest).
3) Match contract length to your risk and plans
Winter-focused fixes are often 12–24 months. Longer terms can offer stability but may have higher exit costs if you move premises.
4) Check payment method and billing frequency
Direct debit vs. invoice, monthly vs. quarterly—these can affect cashflow even when the unit rates look similar.
5) Confirm what happens at renewal
Ask about renewal notices and rollover terms so you don’t drift onto expensive out-of-contract rates next winter.
Quick comparison table: what to check on a fixed-rate quote
| Quote item | Why it matters | What to look for |
|---|---|---|
| Unit rate | Main driver of cost at higher usage | Competitive p/kWh for your profile and region |
| Standing charge | Impacts low/variable usage sites | Low p/day without compromising service/terms |
| Contract term | Affects stability and flexibility | 12–36 months aligned with your plans |
| Exit fees | Costs if you leave early or move | Clear fees and transfer options on relocation |
| Billing & payment | Cashflow and admin time | Monthly invoicing, DD options if preferred |
| Supplier service | Resolution speed during busy periods | Account management, online portal, support |

Who can get fixed business energy rates?
Most UK organisations can take a fixed business electricity and/or gas contract, but what’s available can depend on metering, credit and site details. EnergyPlus can help if you’re:
A microbusiness or small business

- Single-site and small multi-site portfolios
- Businesses currently out of contract
An SME or larger operation

Landlords & managed properties: If you’re responsible for the energy contract for communal areas or empty units, we can help source fixed rates (subject to supplier requirements and tenancy arrangements).
Common mistakes when chasing the cheapest fixed rates
Winter switching pressure can lead to quick decisions. These are the pitfalls that often make a “cheap” quote expensive over the full term.
Only comparing p/kWh
Standing charges and usage patterns matter. We compare total cost using your expected consumption where possible.
Missing the renewal window
Leaving it late can mean fewer options or rolling onto out-of-contract rates. If you know your end date, start early.
Choosing the wrong term
A longer fix can be great for stability, but it’s not ideal if you may move or downsize. We’ll talk through flexibility vs. certainty.
Not checking contract details
Exit fees, billing arrangements and renewal terms should be clear before you proceed—especially across multiple meters.
Using estimated usage that’s way off
Inaccurate consumption assumptions can distort which deal is “cheapest”. A recent bill helps sharpen the comparison.
Ignoring operational changes
New equipment, extended hours or seasonal peaks can alter your profile. Tell us what’s changing so quotes match reality.
FAQs: cheapest fixed business energy rates (UK)
Are fixed business energy rates cheaper in winter?
Not always. Winter can bring higher demand and faster market moves. The “cheapest” fixed deal is the one priced well for your meter and usage at the time you secure it. Comparing whole-of-market gives you the best chance of finding competitive pricing when rates change.
Can I switch if I’m out of contract?
Yes. If you’re out of contract, you may be on variable or deemed rates. We can check fixed contracts available for your supply and help you move to a better deal, subject to supplier checks and switching timelines.
When should I renew my business energy contract?
Ideally before your end date so you avoid rolling onto expensive default pricing. Renewal windows vary. Share your contract end date in the quote form and we’ll advise the best time to lock a fixed rate.
Do you compare all suppliers?
EnergyPlus is a whole-of-market comparison service for business energy. Supplier availability can depend on region, meter type, credit and commercial criteria. We’ll present the competitive options available to your business at the time of quoting.
Will a fixed contract include VAT and Climate Change Levy?
Business energy bills can include VAT and, where applicable, the Climate Change Levy (CCL). Eligibility for reduced VAT or exemptions depends on your organisation and usage. If you’re unsure, mention it when you request quotes and we’ll explain what typically applies.
Can I fix electricity only, gas only, or both?
Yes. You can take a fixed electricity contract, a fixed gas contract, or dual fuel. Dual fuel can simplify admin, but the cheapest option sometimes comes from separate suppliers—whole-of-market comparison helps you see both approaches.
