Micro business energy rates: what you can pay and how to compare
A UK guide for small firms on what counts as a micro business, what affects your electricity and gas prices, and how to compare whole-of-market quotes with the right protections and paperwork.
- Understand micro business eligibility and the extra supplier obligations that come with it
- See what drives your rate: meter type, consumption, payment method, contract length and risk
- Get a like-for-like comparison checklist (no guesswork, no invented rates)
Estimates and availability vary by postcode, meter, credit checks and supplier terms. We’ll show what to gather so your quotes are accurate.
Fast answer: micro business energy rates
Micro business energy rates are the electricity and gas prices offered to eligible small UK firms; the biggest driver is your annual usage (kWh), because it determines the contract band suppliers quote against. Rates then vary by postcode, meter type (including smart/half-hourly), payment method, credit checks and contract length—so the only reliable way to know yours is to compare quotes using your meter and consumption details.
Key takeaway #1
If you qualify as a micro business, suppliers have extra rules on contracts and sales conduct. Ask to be treated as micro if you meet the criteria.
Key takeaway #2
To compare like-for-like, you need: MPAN/MPRN, current contract end date, meter type and 12-month usage (or recent bills).
Key takeaway #3
Don’t focus only on unit rate. Standing charge, contract length, pass-through charges and exit fees can change the real cost.
Important: We don’t publish “typical” micro business p/kWh figures on this page because prices move and vary heavily by meter profile and usage band. Use the quote journey for current, postcode- and meter-specific prices.
Compare micro business energy rates (without wasting time)
If you’re a micro business, you often have fewer admin resources—so the goal is getting accurate quotes fast, then checking the terms that change the real cost.
What to gather before you request quotes
- Your meter identifiers (MPAN / MPRN)
- Found on your bill. This helps suppliers match your supply point and meter details.
- Annual usage (kWh) or recent bills
- If you don’t have 12 months’ usage, 3–6 bills can still produce a usable estimate (with wider variation).
- Current contract details
- End date, renewal window, and any known exit fees. This affects when you can switch and what to compare against.
- Meter type and billing preference
- Smart/half-hourly and payment method can change pricing. Tell us if you need paper bills or consolidated invoicing.
Micro business eligibility (high level): Ofgem defines a micro business using criteria such as employee count and annual turnover/balance sheet, or low energy consumption thresholds. If you’re not sure, request quotes anyway and ask the supplier to confirm your status.

Tell us a few details and we’ll use them to source suitable business energy options. For accuracy, use the details from your latest bill.
How comparing micro business rates works (and what can slow it down)
- We capture your supply details (postcode, fuel, and ideally MPAN/MPRN and usage) so quotes match your meter and network area.
- Suppliers return prices and contract options based on risk, usage band and contract length. Not all suppliers will quote for every meter type or profile.
- We help you compare like-for-like by checking the components that matter: unit rate, standing charge, contract term, billing method and any pass-through items.
- You choose a contract and switch date that avoids early termination charges where possible. If you’re out of contract, you can usually start sooner.
- Switching is processed with your supplier. Your energy supply doesn’t physically stop; it’s a change of billing and contract.
What speeds up accurate quotes
- MPAN/MPRN and a recent bill to confirm meter and profile
- 12-month consumption (or best available estimate)
- Your current contract end date and renewal window
- Knowing whether you have half-hourly (HH) electricity metering
What can limit options
- Complex meter setups (multiple meters, landlord supplies, sub-meters)
- Short trading history or credit constraints (suppliers may request deposits)
- Very low usage (some suppliers may not prioritise bespoke quotes)
- Unclear occupancy responsibility (who is the “deemed” customer)
If anything is unclear, it’s better to be upfront—incorrect consumption or meter info can produce quotes that look cheap but don’t hold when the supplier validates the supply details.
What affects micro business energy rates in the UK
Micro business pricing is commercial pricing. It’s built from wholesale costs, network charges, policy costs and supplier costs—then adjusted for your site and usage pattern.
1) Annual consumption (kWh)
Suppliers typically quote in consumption “bands”. Moving band can change pricing materially even if the premises is the same.
2) Meter type and profile
Half-hourly (HH) meters price differently to non-HH. Smart meters can improve data quality, but don’t guarantee cheaper rates.
3) Location and network area
Distribution charges vary by region. Two identical cafés can see different total costs purely due to network differences.
4) Contract length and start date
Longer fixes can add certainty but may include exit fees. Timing matters because wholesale prices move daily.
5) Payment method and billing
Direct debit vs other payment methods, paper vs e-billing, and invoice frequency can affect supplier costs and pricing.
6) Credit and trading history
Some suppliers may quote higher, request deposits, or decline depending on credit checks and account history.
Micro business protections: Micro business consumers have specific protections around contracts and sales practices under Ofgem rules. If you think you qualify but aren’t being treated as micro, raise it with the supplier and keep a written record of what you asked for and when.
Two realistic scenarios (illustrative, not live rates)
The examples below show how bill totals can shift based on standing charge and usage assumptions, without using live market unit rates. Replace the assumptions with your real numbers during quoting.
Scenario A: low-usage office with higher standing charge
- Assumption: 7,500 kWh electricity per year
- Plan 1 (illustrative): 55p/day standing charge
- Plan 2 (illustrative): 35p/day standing charge
Standing charge difference: 20p/day ≈ £73/year (20p × 365). If unit rates are similar, the lower standing charge can matter more for low usage.
Note: Actual standing charges vary by supplier, meter and region; the quote results will show live figures.
Scenario B: small restaurant where unit rate matters most
- Assumption: 55,000 kWh electricity per year (evening-heavy usage)
- Plan 1 vs Plan 2 (illustrative): unit rate difference of 1.2p/kWh
Unit rate difference: 1.2p × 55,000 kWh = £660/year. For higher usage, small changes in p/kWh can outweigh standing charge differences.
Note: HH meters and time-of-use patterns can change what “cheapest” looks like—compare using your real meter profile.
Micro business energy plans: what to compare (not just price)
Use this table to compare contract types consistently. Exact pricing and availability changes—your quotes will show the current market options for your postcode and meter.
| Option | Best for | Watch-outs | What to confirm in writing |
|---|---|---|---|
| Fixed term (e.g. 12–36 months) | Budget certainty and stable cashflow planning | Exit fees; renewal windows; pass-through items can still change | Unit rate, standing charge, term, end date, exit fees, billing frequency |
| Flexible / variable | Short commitments; uncertain tenancy; new businesses testing usage | Prices can change; budget volatility | How and when rates change; notice periods; any admin fees |
| Deemed / out-of-contract | Stop-gap if you’ve moved in or contract ended | Often expensive; unclear responsibility if tenancy changes | Who is liable; start date; how to move to a contracted rate |
| HH / smart-profiled pricing | Sites with HH meters or clear load shifting opportunities | Complex bills; costs depend on actual usage profile | How HH data is billed; reconciliation approach; reporting provided |
Decision checklist: who this guide suits (and who it doesn’t)
This is for you if…
- You’re a small UK business and want quotes aligned to your meter and usage
- You need to avoid rolling onto expensive out-of-contract or deemed rates
- You want to compare terms (exit fees, pass-through, billing) not just “headline” pricing
It may not be enough if…
- You’re multi-site with many meters and need a tender-style procurement process
- You require bespoke reporting, HH optimisation, or complex pass-through structures
- You’re in a serviced office / landlord supply where you can’t choose the supplier
Costs, exclusions and common pitfalls (micro business)
These are the issues that most often cause bill surprises or switching delays. They’re also the easiest to avoid with a quick pre-check.
Auto-rollovers and renewal windows
Some contracts move you onto a new arrangement at renewal. Confirm your renewal window and get quotes early enough to avoid rushed decisions.
Exit fees and termination notice
Leaving before the end date can trigger charges. Always confirm whether fees apply and what notice period is required.
Estimated bills and wrong usage
If a quote is based on underestimated consumption, you can end up paying more in practice. Provide accurate kWh and submit meter reads where applicable.
Pass-through and non-energy charges
Some costs can be passed through separately (especially on more complex meters). Ask what’s included in the headline rates and what can vary.
Change of tenancy (CoT) confusion
If you’ve moved premises, you may be on deemed rates until CoT is processed. Keep tenancy start dates and opening reads to hand.
Multiple meters at one site
A single postcode can have several MPANs/MPRNs. Missing one can create partial switches and messy billing—confirm all meters on your bill.
Practical tip: When you receive quotes, ask for a written summary including: contract start/end dates, unit rate(s), standing charge, billing frequency, payment method assumptions, and any exit fees. If anything is “to be confirmed later”, treat it as a risk and clarify before agreeing.
FAQs: micro business energy rates
What is a micro business for energy in the UK?
A micro business is a type of non-domestic customer defined by Ofgem criteria (commonly based on employee/turnover measures or low annual energy use). If you meet the definition, suppliers must follow extra rules on sales and contract practices. If unsure, ask the supplier to confirm your status in writing.
Are micro business energy rates capped like domestic prices?
Generally, no. The Ofgem price cap applies to domestic standard variable and prepayment tariffs, not typical business contracts. Micro businesses do have specific protections under Ofgem rules, but pricing is still commercial and varies by supplier, meter and usage.
Why do micro business energy quotes vary so much?
Quotes can differ because suppliers price risk and costs differently. Your usage band, meter type (including half-hourly), network region, payment method, credit checks, and contract term all affect the rates you’re offered. Even small differences in assumed usage can change the quote.
What details do I need to get accurate micro business energy rates?
For the most accurate quotes, provide your postcode, MPAN (electricity) and/or MPRN (gas), your current contract end date, meter type (including whether electricity is half-hourly), and your annual kWh usage (or recent bills). Without these, suppliers may quote on estimates that can change later.
Can I switch micro business energy supplier if I’m in contract?
You can usually agree a new contract to start when your current one ends, but switching early may trigger termination fees depending on your terms. Check your end date, any notice requirements, and whether exit fees apply before committing to a new start date.
What is a deemed contract and why can it be expensive?
A deemed contract can apply when you take responsibility for a premises but haven’t agreed a formal contract with a supplier (for example, after moving in). It’s designed as a default arrangement, and the rates can be higher than negotiated contracts. Moving onto a contracted rate typically requires confirming occupancy and supply details.
Do smart or half-hourly meters change micro business energy rates?
They can. Half-hourly (HH) metering means your usage profile is measured in detail, which can change how suppliers price your supply and how bills are calculated. Smart meters can improve accuracy of reads, but they don’t automatically mean cheaper rates—comparison should be based on your actual profile and requirements.
How long does it take to switch micro business energy?
Timescales vary based on your meter, current supplier processes, and whether you’re switching at contract end or mid-term. A switch is often smoother when scheduled for the natural contract end date and when your MPAN/MPRN and tenancy details are correct. Your chosen supplier will confirm the expected timeline once the application is validated.
Trust, methodology and sources
How we assess “micro business energy rates” on this page
- We focus on decision factors that stay true across market cycles: usage bands, meter type, region/network charges, credit factors and contract terms.
- We do not publish live p/kWh or standing charges here because they’re highly variable and time-sensitive; your quote results provide current figures for your postcode and meter setup.
- We use transparent examples that show the maths (e.g., standing charge per day × 365; unit-rate difference × kWh) rather than implying any supplier offers a specific rate.
- Limitations: Some supplier terms and charges depend on individual underwriting, meter data validation, pass-through arrangements and start date availability.
Editorial promise: We aim to be accurate and practical. If you spot something that’s unclear or potentially out of date, use the quote journey to view current market options and treat written supplier terms as the final source of truth.
