Fast answer: business electricity rates per kWh for a small factory
Business electricity rates per kWh for a small factory are usually driven most by your meter type and load profile (when you use power), not just total kWh. In practice, two factories with the same annual usage can get very different p/kWh if one runs steady daytime load and the other has short, high-demand peaks. Get quotes using your MPAN, postcode and recent kWh.
Most important drivers
- Meter: smart/Half-Hourly vs non-HH
- Peak demand & start-up loads
- Operating hours (day vs evening/weekend)
- Contract term & risk appetite
What to gather
- MPAN (electricity supply number)
- Postcode + site address
- Annual kWh and last 2–3 bills
- Current contract end date
Quick reality check
If your p/kWh looks low but the standing charge, pass-through items or capacity charges are high, your total bill may still be expensive. Always compare expected monthly spend, not just unit rate.
Important: We don’t publish live p/kWh figures here because business prices move daily and vary by site. Use the quote journey to see current, postcode-accurate rates and terms.
Get accurate small-factory p/kWh quotes (whole of market)
Because factory usage can be “spiky”, the best way to understand your likely business electricity rates per kWh is to quote against your actual meter details and recent consumption. We’ll use your information to request priced options and show like-for-like comparisons (unit rate, standing charge and key terms) where available.
What happens next
- Share your site details and contact info (below).
- We match your meter type (e.g. half-hourly) and usage shape where possible.
- You receive options to review—then choose if/when to switch.
Tip for small factories: If you have multiple units, sub-meters, or a landlord meter, mention it. It can affect eligibility and how your bill is structured.

What sets a small factory’s electricity rate per kWh?
Business electricity pricing is built from more than “energy” alone. For factories and workshops, the biggest differences in p/kWh usually come from how steady your demand is (load profile), whether you’re metered half-hourly, and the risk level in your contract structure (fixed vs flexible elements).
Factory-specific drivers
- Start-up and peak loads
- Compressors, extraction, ovens, welders and motors can create short peaks that change your profile and, on some setups, your network-related charges.
- Operating schedule
- Daytime-only manufacturing can price differently versus evening/weekend operations because wholesale and system costs vary by time.
- Power factor and site equipment
- Poor power factor can increase certain costs on larger/HH sites. If you’ve had penalty charges before, flag this early.
Commercial/contract drivers
- Contract length
- Longer terms can reduce exposure to price swings but may include stricter exit terms. Shorter terms can be more flexible but may reprice sooner.
- Payment method
- Direct debit vs receipt of bill can affect pricing and credit requirements.
- Pass-through vs all-inclusive
- Some deals bundle most costs into a single p/kWh; others separate out network and policy costs that may move over time.
Two realistic small-factory scenarios (with numbers)
These scenarios help you estimate the “shape” of your costs and what to ask for in quotes. They are illustrations, not market rates: we use placeholder unit rates and standing charges so you can see the maths without implying live pricing.
Scenario A: Day-shift joinery workshop (steady load)
- Usage: 60,000 kWh/year (5,000 kWh/month)
- Hours: Mon–Fri, mostly 08:00–17:00
- Meter: standard business meter (non-HH) or smart with limited variability
Illustrative bill maths
- Assume unit rate: £0.25/kWh (placeholder)
- Assume standing charge: £1.00/day (placeholder)
- Monthly energy: 5,000 × £0.25 = £1,250
- Monthly standing: ~30 × £1.00 = £30
- Estimated monthly subtotal: £1,280 (before VAT and any pass-through items)
Scenario B: Small food production unit (spiky demand)
- Usage: 60,000 kWh/year (same total)
- Hours: early starts + batch runs; refrigeration always on
- Meter: half-hourly (HH) more likely due to load characteristics/site setup
Illustrative bill maths
- Assume unit rate: £0.28/kWh (placeholder reflecting risk)
- Assume standing charge: £1.20/day (placeholder)
- Monthly energy: 5,000 × £0.28 = £1,400
- Monthly standing: ~30 × £1.20 = £36
- Estimated monthly subtotal: £1,436 (before VAT and any pass-through items)
How to use these: The point isn’t the placeholder p/kWh—it’s that “spiky” usage can price differently. When you request quotes, ask for an estimate of monthly cost and a clear view of what’s included (unit rate/standing charge and any variable items).
Compare options that affect your factory’s p/kWh (and risk)
When you compare quotes for a small factory, don’t stop at p/kWh. Use this table to check what you’re really buying: price certainty, flexibility, and exposure to changes in non-energy costs.
| What you’re comparing | Why it changes cost for factories | Good fit when… | Watch-outs |
|---|---|---|---|
| Contract term (e.g. 12/24/36 months) | Affects how suppliers hedge risk and how long your p/kWh is locked. | You want predictable budgeting for production costs. | Exit fees and renewal windows can be strict. |
| Pricing structure (fixed vs mixed/pass-through) | Determines which parts of your bill can move after you sign. | You can tolerate some variability and want transparency. | Budgeting can be harder; compare expected total cost. |
| Metering (HH vs non-HH) | HH data reflects your actual half-hour usage; spiky loads can price differently. | Your site has clear operational patterns and you want accurate profiling. | If your data is unusual, ask how it was modelled. |
| Standing charge level | High standing charges can punish low-utilisation periods (shutdowns, seasonal work). | You run consistently year-round. | Always convert quotes into expected monthly spend. |
Decision checklist: does a “p/kWh-first” approach suit you?
- Yes if you have stable year-round production and your standing charge is modest.
- Be careful if you have seasonal shutdowns, irregular batch runs, or multiple meters.
- Ask for totals: monthly cost estimates, what’s included, and what can change.
Who this guide is for (and who it isn’t)
- Best for: small factories, industrial units, workshops, light manufacturing SMEs.
- Not a perfect fit: very large sites with complex flexible purchasing or on-site generation/export contracts.
- If unsure: submit the form—include “multi-site” or “multiple meters” in your notes.
Extra costs, exclusions and common pitfalls (small factories)
These are the areas where businesses most often feel “caught out” when they focus only on p/kWh. Use the cards below as a pre-signing checklist and to frame better questions when you request quotes.
1) Standing charge vs usage pattern
A low unit rate can be paired with a higher standing charge. If your factory has downtime (maintenance weeks, seasonal closures), standing charges can dominate your bill.
2) Pass-through items that can move
Some contracts separate out non-energy charges (often called pass-through). Ask which elements are fixed and which may change, and request an “expected total cost” view.
3) Contract end date and rollover risk
Out-of-contract (deemed/rollover) rates can be materially higher and less predictable. Start your comparison well before your renewal window to avoid time pressure.
4) Multiple meters, landlord supplies, sub-metering
If your unit is supplied via a landlord or you have sub-meters, you may not be able to switch the “head” supply directly. Get clarity on who the contracted party is.
5) VAT treatment and eligibility
Business electricity is typically billed with VAT. If you think your business qualifies for a reduced VAT rate in specific circumstances, confirm with your accountant and supplier—don’t assume.
6) Credit checks and security deposits
Some suppliers may request a deposit or different payment terms based on credit assessment. This can affect the “best” option for cashflow—even if the p/kWh looks attractive.
Practical check before you sign: Ask for a written summary of (1) unit rate, (2) standing charge, (3) contract length, (4) termination/renewal window, and (5) which charges are fixed vs variable. Then compare on estimated monthly spend for your usage.
FAQs: small factory electricity rates (UK)
What is a good business electricity rate per kWh for a small factory in the UK?
There isn’t one “good” p/kWh that applies to every small factory because pricing depends heavily on your meter type, load profile, contract term, location and credit checks. The most reliable approach is to compare live quotes using your MPAN, postcode and recent kWh, then judge value on total expected monthly cost and terms.
Why can two similar factories get different p/kWh rates?
Suppliers price risk. Two sites with the same annual kWh can look very different if one has smooth demand and the other has sharp peaks, early starts, or irregular batch runs—especially on half-hourly metering. Location, contract length, payment method and credit assessment can also change the price you’re offered.
Does half-hourly (HH) metering make electricity cheaper for small factories?
Not automatically. HH metering can produce more accurate pricing because it reflects when you use electricity, but it can also highlight peaks that increase your effective cost. For some factories, HH helps unlock better-fitting contracts; for others, it exposes costly usage patterns. The key is to compare quotes using your actual HH data where possible.
What details do I need to get an accurate p/kWh quote?
Have your MPAN, site postcode, estimated annual kWh (or last 2–3 bills), current supplier and contract end date. If you have multiple meters, unusual operating hours, or large motors/compressors, mention it—these can affect how your usage is modelled and priced.
Should I compare quotes on unit rate only, or total bill?
Compare on total expected cost. A low p/kWh can be offset by a higher standing charge or variable pass-through items. Ask for a clear breakdown (unit rate, standing charge, contract length and what can change) and convert each quote into an estimated monthly spend based on your usage.
Can I switch business electricity if I rent a factory unit?
Often yes, but it depends on who the contracted party is and whether you have your own meter and MPAN. If the landlord supplies electricity via a building-wide meter and recharges you, you may not be able to switch the head supply directly. Check your lease and a recent bill before starting a switch.
Are business electricity prices capped by Ofgem like household prices?
Generally, no. The Ofgem price cap applies to certain domestic tariffs, not typical business electricity contracts. Some microbusinesses have extra protections around contracts and sales practices, but that’s different from a price cap. If you’re a small business, it’s worth checking whether you qualify as a microbusiness.
What is a microbusiness and why does it matter for switching?
A microbusiness is a small business that meets certain size and consumption thresholds. If you qualify, you may have additional protections around contract information, termination notices and complaint handling. Eligibility depends on criteria such as employee count and energy usage. When you request quotes, tell us your approximate annual kWh and business size so we can treat your enquiry correctly.

How we assess “rates per kWh” for small factories
We focus on what changes pricing most for small industrial sites: metering type (HH vs non-HH), load profile (steady vs peaky), contract length, payment method, and whether costs are bundled or pass-through. We avoid publishing live p/kWh figures on-page because business pricing varies by postcode and changes frequently.
Assumptions and limitations (please read)
- Scenario numbers use placeholder rates to demonstrate bill maths only.
- Actual quotes depend on supplier appetite, contract terms, credit checks and market conditions.
- Some charges and rules differ by distribution area and metering setup.
