Prices are estimated and depend on your meter, usage, payment terms, credit status and contract conditions. We’ll ask for details so quotes are like-for-like.

Fast answer: how to compare business energy prices for a small business

To compare UK business energy prices properly, you need quotes that match on meter type (smart, non-smart, half-hourly), contract length, payment method (direct debit vs invoice), unit rate (p/kWh), standing charge (p/day), and any extras (broker fees, pass-through charges, renewable claims, termination terms). Without these, you can end up comparing deals that look cheap but cost more once contract terms and charges are included.

What you need to compare

  • MPAN (electricity) / MPRN (gas)
  • Annual kWh usage (or last 12 months)
  • Meter type: standard, smart, or half-hourly
  • Current contract end date + any notice period

What most affects your price

  • Contract length (shorter can cost more per kWh)
  • Credit terms (deposit, payment in advance, or invoice)
  • Usage profile (day/night split, peaks, seasonality)
  • Region and network costs (varies across the UK)

Quick decision tip

If you want budget certainty, start with a fixed-rate contract and compare total estimated annual cost (unit rate + standing charge). If your site is larger or half-hourly, consider a flexible option—only after understanding pass-through charges.

Important: Business energy is not usually covered by the domestic price cap. Your quote is bespoke to your business and supply details, so “headline rates” online are rarely like-for-like.

Get like-for-like quotes (no guesswork)

Complete the form and we’ll use your details to request comparable business electricity and/or gas quotes across the market. The more accurate your usage and meter details, the fewer re-quotes you’ll get.

Tip: If you have a recent bill, use it. MPAN/MPRN and annual kWh are the fastest way to get accurate pricing.

How business energy comparison works (small business)

  1. We collect the essentials
    Postcode, contact details, and what you want to compare. If you have a bill, MPAN/MPRN and kWh usage help accuracy.
  2. We request like-for-like quotes
    We aim to compare the same start date, term length, payment method and tariff structure (as close as suppliers allow).
  3. We present options with key terms
    Unit rate and standing charge, plus what to look for: termination clauses, auto-renewal, deposits, and pass-through charges.
  4. You choose what fits
    If you proceed, the supplier completes any credit checks and confirms contract documentation.
Good to know: Some businesses are classed as “microbusinesses” and may have extra protections around contracts and complaints. If you’re unsure, ask us and we’ll explain what applies to your site.

What to have ready (if possible)

Electricity MPAN / Gas MPRN
Found on your bill; helps identify your supply and meter details.
Annual consumption (kWh)
If not available, a supplier may estimate based on your profile, which can change the quoted cost.
Contract end date and notice period
Avoids problems with early termination fees and helps time your switch window.

What to compare: tariff types and contract features

Use this table to compare options quickly. The “best” deal depends on your risk tolerance, cash flow, and whether your meter is half-hourly (HH) or non-half-hourly (NHH).

Option How pricing works Pros Watch-outs Often suits
Fixed rate Unit rate and standing charge set for a term (e.g., 12–36 months). Budget certainty; simple to compare; common for SMEs. Early termination fees; renewal terms; check pass-through charges and whether rates are fully fixed. Shops, cafés, offices with steady usage.
Variable / out-of-contract Rates can change (often with notice). Usually a default if your contract ends. No long commitment; useful short-term while you decide. Often higher cost; price rises possible; limited control. Temporary occupancy; awaiting move/lease decision.
Flexible / market-tracked Pricing linked to wholesale market; may allow buying in blocks. Often used for larger or HH sites. Potential to benefit from market dips; custom risk strategy. More complex; cash-flow risk; ensure clarity on pass-through and management fees. Higher usage, HH metering, multi-site, facilities with peaks.
Green / renewable tariffs Suppliers may match consumption with REGOs (electricity) or offer green gas options. Supports sustainability goals; can help procurement policies. “Green” definitions vary; ask what certification is used and what you can claim publicly. Client-facing SMEs; businesses with ESG reporting.

Decision checklist (quick)

  • Do you know your contract end date? If not, check before agreeing to avoid exit fees.
  • Is your meter half-hourly? HH sites often need more detailed pricing.
  • Are you comparing the same term length? 12 vs 36 months can change unit rates.
  • What are the payment terms? Invoice, direct debit, or upfront can affect price.
  • What happens at renewal? Ask about rollover/auto-renewal and notice periods.

Who it suits / who it doesn’t

Comparing usually suits you if:

  • Your renewal is within ~6 months
  • You want clearer budgeting
  • You’ve moved in or taken over a supply
  • You suspect you’re on out-of-contract rates

You may need extra care if:

  • You’re mid-contract (possible termination fees)
  • You have multiple meters or sites
  • Your business has weak credit or recent CCJs
  • Your site is HH and needs specialist pricing

Two realistic examples (with assumptions)

Scenario A: small office (electricity only)

  • Assumed annual usage: 12,000 kWh
  • Tariff 1: 30.0p/kWh + 60p/day standing
  • Tariff 2: 27.5p/kWh + 75p/day standing

Estimated annual cost (energy + standing only):

  • Tariff 1: (12,000 × £0.30) + (365 × £0.60) ˜ £3,819
  • Tariff 2: (12,000 × £0.275) + (365 × £0.75) ˜ £3,574

Even with a higher standing charge, the lower unit rate wins at this usage. At much lower usage, the result can flip.

Scenario B: takeaway (electricity + gas)

  • Assumed annual electricity usage: 25,000 kWh
  • Assumed annual gas usage: 45,000 kWh
  • Electricity quote: 29.0p/kWh + 70p/day
  • Gas quote: 8.0p/kWh + 35p/day

Estimated annual cost (energy + standing only):

  • Electricity: (25,000 × £0.29) + (365 × £0.70) ˜ £7,506
  • Gas: (45,000 × £0.08) + (365 × £0.35) ˜ £3,728
  • Total: ˜ £11,234

This is an estimate. Your actual bills can include VAT, Climate Change Levy (where applicable), and other charges depending on your contract and meter setup.

Assumptions: 365-day year; rates are illustrative examples for comparison education only; excludes VAT, CCL, and any pass-through/third-party charges unless specified in your quote.

Costs, exclusions and common pitfalls (UK business energy)

Small businesses often focus on the unit rate. In practice, contract terms and “extras” can matter just as much. These are the points most likely to change your final cost or cause switching friction.

1) Standing charge vs unit rate trade-offs

A lower p/kWh can come with a higher standing charge. Always compare an estimated annual total using your kWh and days on supply.

2) VAT and Climate Change Levy (CCL)

Many businesses pay 20% VAT, but some may qualify for reduced VAT on energy. CCL may apply depending on your circumstances. Ask what’s included in quoted totals.

3) Pass-through and third-party charges

Some contracts include non-energy charges (for networks and system costs) that can change over time. Clarify whether a quote is “fully fixed” or “partially fixed”.

4) Deposits, credit checks and payment terms

Suppliers may request a deposit or different payment terms (e.g., pay in advance) based on credit assessment. This can change which tariff is available to you.

5) Early termination and renewal clauses

Leaving mid-term can trigger termination fees. Also check renewal windows and whether you must give notice to avoid rolling onto more expensive rates.

6) Wrong meter details = wrong quote

If your meter is HH, multi-rate, or has specific settlement details, a standard SME quote may be reworked. Using MPAN/MPRN and a bill reduces delays.

Don’t rely on “typical prices”: UK business energy pricing depends on your supply point and contract terms. Always ask for a written quote showing unit rate, standing charge, contract length, start date, and what’s included/excluded.

FAQs: comparing business energy prices (UK small business)

1) Is business energy cheaper than domestic energy in the UK?

Not necessarily. Business energy isn’t typically protected by the domestic price cap and pricing is negotiated based on your business, usage and contract. Sometimes business rates can be lower, sometimes higher—especially if you’re out of contract or have higher standing charges.

2) When is the best time to compare business energy deals?

A sensible time is when you’re approaching renewal (often months before the end date) so you have options without risking contract overlap or exit fees. If you’ve moved into new premises, compare as soon as possible to avoid staying on higher deemed or out-of-contract rates.

3) What’s a deemed contract for business energy?

If you move into a property or your fixed term ends without agreeing a new contract, you may be supplied on a deemed or out-of-contract arrangement. Rates can be higher and terms differ by supplier—so it’s worth comparing quickly once you have your supply details.

4) Do I need my MPAN or MPRN to get a quote?

It helps. Many suppliers can quote with postcode and business details, but MPAN/MPRN and annual kWh usually improves accuracy and reduces re-quotes—especially for multi-rate or half-hourly sites.

5) Can I switch business energy suppliers if I rent my premises?

Often yes, but check your lease and who is responsible for utilities. If the energy account is in your business name (or should be), you can usually arrange a contract. If a landlord controls the supply, your options may be limited.

6) Will switching disrupt my supply?

Switching supplier shouldn’t interrupt gas or electricity supply. The physical energy still comes through the same networks; what changes is the billing supplier and contract terms. Delays can happen if meter details or account information don’t match.

7) What’s the difference between half-hourly (HH) and non-half-hourly (NHH) metering?

HH metering records electricity usage every 30 minutes. Pricing can be more complex because your cost can depend on when you use energy (peaks vs off-peak). Many small businesses are NHH, but some sites with higher demand or certain meter configurations are HH.

8) Are “green business energy tariffs” always genuinely renewable?

Definitions vary. Many green electricity tariffs are backed by certificates (such as REGOs). Ask what the supplier provides and what claims you can make. If environmental reporting matters to you, request written confirmation of how renewable supply is evidenced.

How we assess comparisons (our approach)

  • Like-for-like first: we prioritise quotes that match term length, payment method, and supply details.
  • Total cost view: we encourage evaluating estimated annual cost, not just p/kWh.
  • Terms transparency: we flag termination clauses, rollover terms, deposits and pass-through charges.
  • Practical constraints: we consider meter type (HH/NHH), multi-site complexity, and credit outcomes.

Limitations and assumptions (important)

  • Quotes are time-sensitive: supplier pricing can change quickly with the market.
  • Eligibility varies: credit checks, deposits, and payment terms can affect which prices you can access.
  • Charges can differ: some costs may be pass-through or region-specific; ask for a full breakdown.
  • Examples on this page are illustrative: they’re not promises of savings or available rates.

UK sources we rely on

  • Ofgem (UK energy regulator guidance and consumer protections, including microbusiness principles)
  • Citizens Advice: energy supply (practical guidance on bills, complaints and switching)
  • GOV.UK business (business support and compliance context, including VAT where relevant)

We aim to keep this page accurate and updated, but supplier terms and market pricing can change. Always check the final contract documentation before agreeing.
