Estimates only. Prices and availability vary by meter type, credit status, region and contract terms. We’ll confirm details before any switch.

Business energy comparison: the fast answer

In the UK, business energy prices are usually offered as contract quotes (not public “one-size” rates). Comparing properly means matching your meter type, expected usage, payment method and contract length to the supplier’s available tariffs—then checking the terms that affect your true cost, like standing charges, unit rates, pass-through charges (common for larger sites), and exit fees.

What you’ll need

  • Postcode + business name
  • Meter details (MPAN/MPRN if available)
  • Estimate of annual kWh (or last bill)

Big factors that move price

  • Contract length (12–36 months typical)
  • Meter type (smart / half-hourly / non-HH)
  • Credit status and payment type (DD vs receipt)

Quick red flags

  • Auto-rollover to expensive out-of-contract rates
  • Undisclosed pass-through charges
  • Long notice periods / termination windows

Microbusiness? You may have extra protections around contract information and dispute resolution. We cover what that means (and how to check eligibility) below.

Compare business energy deals (whole-of-market)

Complete the form and we’ll use your details to request available quotes for your meter and site. If you have a recent bill, we can match the structure more accurately (including standing charges and any pass-through elements where applicable).

Best for

  • SMEs looking for a fixed rate at renewal
  • Businesses moving premises
  • Multi-site portfolios needing one view

Not ideal if

  • You need same-day switching (rare in business energy)
  • Your meter details are unknown and you can’t share a bill
  • You’re in a complex tenancy with landlord-supplied energy

What happens next: We’ll confirm meter type (e.g., smart / half-hourly), current contract end date (if known), and whether you want electricity, gas or both. No savings promises—quotes depend on supplier criteria and market rates.

How business energy comparison & switching works

  1. We collect the essentials: postcode, fuel type, and contact details. If you can share a bill later, we’ll validate usage and meter identifiers (MPAN for electricity, MPRN for gas).
  2. We confirm your supply profile: meter type (standard/smart/half-hourly), expected annual kWh, payment preferences, and whether you’re in-contract or out-of-contract.
  3. We request quotes: suppliers price differently by region, industry type, consumption band and credit checks. Not every supplier will quote every business.
  4. You compare like-for-like: unit rates, standing charges, contract length, pass-through structure (where applicable), and termination/renewal terms.
  5. Switching (if you choose to): a new contract is set for your chosen start date—often aligned with your current end date to avoid exit fees. You’ll keep supply during the changeover; only billing changes.

Important: Business energy doesn’t have the same switching rules as domestic. Cooling-off periods, deemed rates and renewal notices vary by supplier and contract. Always check the written terms.

Compare business energy options (what to look at)

The “best” deal depends on how your business uses energy and how your contract is structured. Use the table to compare options quickly, then apply the checklist underneath to avoid expensive surprises.

Option Typical fit Pros Watch-outs
Fixed-rate (1–3 years) Most SMEs, especially at renewal Budget certainty; easier comparisons Exit fees if you leave early; renewal notice windows
Variable / out-of-contract Short-term stopgap only Flexibility; no long tie-in Often significantly higher; can change with notice
Deemed / emergency rates Moved in without setting up a contract Keeps energy on while you arrange supply Commonly expensive; act quickly to agree a contract
Pass-through / flex structures Higher usage, multi-site, half-hourly meters Can reflect actual network/system costs Harder to compare; ensure clear list of pass-through items

Decision checklist (practical)

  • Contract end date: are you in a termination window to avoid rollover?
  • Meter type: standard/smart/half-hourly (HH) affects what suppliers will quote.
  • Usage estimate: annual kWh and day/night split (if applicable).
  • Price structure: unit rate + standing charge; for larger sites ask what’s pass-through.
  • Fees: exit fees, admin fees, late payment charges, and paper billing fees.
  • Payment: direct debit vs receipt/invoice can change pricing.
  • Green claims: ask how “renewable” is evidenced (e.g., REGO-backed electricity).

Two realistic examples (with assumptions)

Example A: single-site café (electricity only)
Assumptions: 18,000 kWh/year, single-rate meter, standing charge 60p/day, 12-month fixed, unit rate 28p/kWh (estimated).
Estimated annual energy cost = (18,000 × £0.28) + (365 × £0.60) = £5,040 + £219 = £5,259 (ex VAT).
What changes the result: higher standing charge, seasonal usage spikes, or being on out-of-contract rates.

Example B: light industrial unit (electricity + gas)
Assumptions: Electricity 95,000 kWh/year at 24p/kWh + 80p/day standing; Gas 180,000 kWh/year at 7.2p/kWh + 75p/day standing; 24-month fixed (estimated).
Estimated annual electricity cost = (95,000 × £0.24) + (365 × £0.80) = £22,800 + £292 = £23,092 (ex VAT).
Estimated annual gas cost = (180,000 × £0.072) + (365 × £0.75) = £12,960 + £274 = £13,234 (ex VAT).
Combined estimated annual = £36,326 (ex VAT). Pass-through/network charges may apply depending on meter and contract structure.

About VAT: Many business energy contracts are priced excluding VAT. Some businesses may be eligible for reduced VAT (e.g., 5%) under certain conditions; check your accountant/supplier and HMRC guidance if relevant.

Costs, exclusions & common pitfalls (UK business energy)

When a quote looks “too good”, it’s often because something isn’t being compared like-for-like. These are the cost areas we recommend checking before you sign.

1) Rollover & notice windows

Some contracts require you to give notice within a specific window (for example, 30–120 days before end). Missing it can mean rolling onto higher rates or a renewed term.

2) Exit fees & moving premises

Leaving early may trigger termination fees. If you’re relocating, check whether the contract is portable to the new address and what happens if the supplier can’t support it.

3) Pass-through charges

Larger or HH supplies may include charges that vary (network/system). Ask for a clear list of what is fixed vs pass-through so you can compare fairly.

4) Standing charges

A low unit rate can be offset by a higher daily standing charge—especially for low-consumption sites (small offices, salons, storage units).

5) Payment method pricing

Direct debit is often priced differently to pay-on-receipt. If cashflow matters, compare both—but confirm whether the quoted rates assume DD.

6) Estimated usage vs actuals

Quotes use expected kWh. If your estimate is far off, the “cheapest” deal may not be cheapest at your true usage. A recent bill improves accuracy.

Exclusions to be aware of: Some suppliers won’t quote certain business types, may require a credit check, and may not support particular meters/regions. Multi-site portfolios may receive bespoke terms rather than standard SME rates.

Business energy comparison FAQs

Is business energy cheaper than domestic?

Not necessarily. Business pricing is quote-based and depends on usage, meter type, contract length, and credit checks. Also note business prices are commonly shown ex VAT, which can make headline figures look lower than domestic at first glance.

What’s a “microbusiness” and why does it matter?

A microbusiness is a small business that may receive extra protections in areas like contract information. Eligibility can depend on employee numbers and/or annual consumption thresholds. If you think you qualify, it’s worth stating this during the quote process.

Do I need my MPAN/MPRN to compare?

It helps but it isn’t always essential for an initial discussion. A recent bill is often enough to confirm your identifiers, meter type, and consumption. Without these, quotes may be broader estimates or take longer to validate.

Can I switch if I’m in contract?

You can request quotes at any time, but switching before your contract end date may trigger exit fees. Many businesses compare ahead of renewal and set a start date to align with the end of the current term.

What are deemed rates and when do they apply?

Deemed rates can apply when you move into premises and start using energy without agreeing a contract with a supplier. They keep you supplied, but they’re often expensive—so it’s usually best to agree a contract promptly once you have occupancy.

Are green business energy tariffs always 100% renewable?

Definitions vary. In the UK, renewable electricity claims are often supported by certificate schemes (such as REGO). Ask suppliers how the claim is evidenced and whether there are additional costs or contract conditions.

What if I have a half-hourly (HH) meter?

HH meters record usage in 30-minute intervals and can lead to different contract structures. Some quotes may include pass-through elements and require more detailed usage data. We’ll confirm what’s needed and help you compare on a fair basis.

How long does business energy switching take?

Timescales vary by supplier, meter type and your preferred start date (often aligned with your contract end date). The key is allowing enough time to compare quotes and avoid rollover windows.

If you’re unsure what contract you’re on, start with your latest bill: it normally shows your tariff type, rates, and how to contact the supplier to confirm your end date and any termination requirements.

How we assess business energy deals (and limitations)

Our comparison guidance focuses on the factors that most reliably affect business energy outcomes: total cost structure (unit rate + standing charge), contract terms (length, renewal and termination windows, exit fees), meter type (including HH), payment method and supplier eligibility.

  • Assumptions in examples: The scenario calculations use simple annualised maths from published-style fields (kWh and daily standing charge). They exclude VAT and any variable pass-through charges unless stated.
  • Quote variability: Business quotes can vary by credit checks, usage band, region and supplier appetite. Some suppliers may not quote every sector or meter configuration.
  • Contract complexity: Larger usage and HH contracts may include pass-through items that make “p/kWh” alone misleading. We encourage reviewing a written breakdown before agreeing.
  • Market movement: Wholesale energy prices and supplier pricing can change. A quote is time-limited.

What we do (and don’t) promise

We aim to make comparison clearer and reduce admin time. We don’t guarantee the cheapest tariff for every business or guaranteed savings. Your final rates depend on supplier approval, meter details and the contract you select.

Tip: If you want the most accurate comparison, have one recent bill to hand—especially if you suspect you have a smart meter with HH settlement or a contract with pass-through charges.
