What Is SmartestEnergy Business?
SmartestEnergy Business Limited is a UK non-domestic energy supplier focused particularly on small and medium-sized businesses and its history dates back to 2009, when Dual Energy entered the UK SME electricity market.
SmartestEnergy Business states that:
Dual Energy launched in 2009
it began offering smart meters to businesses in 2010
SmartestEnergy acquired the business in 2019
it obtained its gas supplier licence and rebranded as SmartestEnergy Business in 2020
it launched its renewable product range in 2021
Their website says they have now powered more than:
100,000 businesses since 2009.
It reports approximately 84,000 active supply points
and 1.99 TWh annual volume.
SmartestEnergy Business is ultimately backed by Japanese trading and investment group Marubeni Corporation.
SmartestEnergy Business vs SmartestEnergy Limited
SmartestEnergy Business and SmartestEnergy Limited are closely related, but businesses should not treat their propositions as identical – SmartestEnergy Business focuses heavily on SME and mid-market customers.
Its products include:
SmartFix Standard
SmartFix Renewable
SmartFix Zero
SmartTracker
SmartestEnergy Limited has a separate commercial and industrial proposition aimed at larger energy users which includes more sophisticated services such as:
large-business fixed electricity
flexible electricity procurement
renewable supply products
Corporate PPAs
PPAs for generators
SmartestEnergy currently directs micro and smaller businesses towards SmartestEnergy Business.
For most SMEs searching for SmartestEnergy business gas or electricity, SmartestEnergy Business is therefore the more relevant proposition.
SmartestEnergy Business Prices
SmartestEnergy Business does not have one universal electricity or gas rate for every company so your business energy quotes can depend on:
annual electricity consumption
annual gas consumption
business postcode
meter type
consumption profile
product selected
contract duration
wholesale market conditions
network and other non-energy costs
A quote often will include:
Unit rate – the amount charged for each kWh consumed.
Standing charge – a daily fixed amount, where applicable.
SmartFix Zero works differently because eligible businesses pay: £0 standing charge.
However, that does not automatically mean SmartFix Zero produces the lowest annual bill.
The unit price still matters so always compare the complete estimated annual cost.
See our business energy prices guide for current market information.
Compare Current Business Energy Prices
How Much Could SmartestEnergy Business Cost?
For a conventional tariff, an approximate annual cost can be calculated using annual consumption × unit rate + annual standing charge + applicable additional costs.
For example:
A business using relatively little electricity may find the standing charge represents a meaningful percentage of its overall bill.
A high-consumption business is usually much more sensitive to differences in the unit rate.
which is why SmartFix Zero can be particularly interesting for:
seasonal businesses
low-consumption premises
businesses with irregular opening hours
But: £0 standing charge does not mean £0 fixed cost overall or guarantee the cheapest energy.
Compare the unit rate as well.
Use our business energy bill calculator to estimate annual costs.
SmartestEnergy Business Tariffs
SmartestEnergy Business currently offers several distinct energy products.
Product
Fuel
Structure
Potential Use
SmartFix Standard
Electricity and/or gas
Fixed
Businesses wanting greater price certainty
SmartFix Renewable
Electricity
Fixed renewable
Businesses wanting renewable electricity and price certainty
SmartFix Zero
Electricity
Fixed with zero standing charge
Eligible low-use, seasonal or variable-consumption businesses
SmartTracker
Electricity and/or gas
Market-tracking
Businesses comfortable tracking market pricing
The right tariff depends on whether your priority is certainty, renewable electricity, lower fixed charges or exposure to market pricing.
SmartFix Standard
SmartFix Standard is SmartestEnergy Business’s conventional fixed-price proposition and is available for: electricity and/or gas.
Contract options are available for multiple years, with SmartestEnergy Business currently promoting fixed products for terms of up to five years depending on the applicable product and quote.
A fixed product can help businesses:
protect against wholesale-price increases
forecast energy expenditure
simplify budgeting
reduce exposure to short-term market volatility
However, fixing has a trade-off.
If market prices subsequently fall, the business doesn’t automatically benefit from those lower wholesale prices during the fixed contract.
Before accepting SmartFix Standard, compare:
unit rate
standing charge
contract duration
pass-through charges
termination terms
estimated annual cost
See our business energy contracts guide .
SmartFix Renewable
SmartFix Renewable combines fixed pricing with renewable electricity, and SmartestEnergy Business says its renewable electricity is sourced from clean sources including:
Their renewable electricity products are independently verified by the Carbon Trust to confirm that every megawatt hour is backed by UK-recognised renewable certificates and SmartestEnergy Business also supports tree planting in connection with its renewable customers.
Businesses choosing renewable electricity should still check the specific credentials and evidence supplied with their individual product.
Renewable electricity can be relevant to organisations working towards:
carbon-reduction targets
ESG objectives
Scope 2 reporting
customer sustainability requirements
SmartFix Zero: Zero Standing Charge Business Electricity
SmartFix Zero is one of the most distinctive products in the SmartestEnergy Business range, as it removes the normal daily electricity standing charge.
Eligible businesses therefore pay: £0 daily standing charge.
Instead, the business pays for the electricity it consumes according to its applicable unit rate and the product also includes:
fixed electricity unit rates
contract options from 1–5 years
renewable electricity option
flexible payment options
SmartWeb online account management
smart-meter services
SmartestEnergy Business says SmartFix Zero can be particularly useful for:
hospitality businesses
hotels and B&Bs
pubs
restaurants
cafés
small retailers
pop-up businesses
offices with low consumption
seasonal businesses
temporary operations
Who Qualifies for SmartFix Zero?
SmartestEnergy Business currently states that SmartFix Zero is available to businesses with a non-half-hourly electricity meter
and annual electricity usage between 1,500 kWh and 25,000 kWh.
Eligibility is checked during the contract application – this means SmartFix Zero is specifically positioned towards smaller electricity users rather than major commercial sites.
Businesses using Half Hourly meters or substantially more electricity will need to consider other products.
Is a Zero Standing Charge Tariff Cheaper?
Not necessarily.
A zero-standing-charge tariff eliminates one part of the bill but total cost still depends on unit rate × electricity consumed.
Imagine
Tariff A has no standing charge but a higher unit rate.
Tariff B has a daily standing charge but a lower unit rate.
A low-consumption or seasonal business could potentially benefit more from Tariff A.
A high-consumption business might save more under Tariff B.
The break-even point depends on the actual rates offered, which makes estimated annual cost the most useful comparison.
SmartTracker Business Energy
SmartTracker provides an alternative to fixing your business energy price at one point in time and its currently available for:
electricity and/or gas.
SmartestEnergy Business positions SmartTracker for companies willing to track the energy market rather than locking into a conventional fixed price – their current product information describes SmartTracker as a three-year proposition.
This can potentially allow businesses to benefit from market-price movements.
However, the reverse also applies.
If market prices rise, a tracking product can expose the business to higher prices.
SmartTracker is therefore more appropriate where a business:
understands variable energy pricing
can tolerate changing energy costs
values flexibility
doesn’t require complete price certainty

The eventual result depends on the contracted rates and what subsequently happens in the energy market.
SmartestEnergy Business Electricity
SmartestEnergy Business supplies electricity to UK companies across a range of sizes and sectors and options include:
standard fixed electricity
renewable fixed electricity
zero-standing-charge electricity
market-tracking electricity
This gives businesses more choice than a supplier offering only one conventional fixed product.
Electricity quotes should still be compared based on:
unit rate
standing charge
annual consumption
contract duration
renewable credentials
non-energy costs
total annual cost
See our business electricity guide .
SmartestEnergy Business Gas
SmartestEnergy Business also supplies gas.
Business gas is available through products including:
SmartFix Standard
SmartTracker
The supplier also provides SmartPay options for eligible customers – SmartPay is an advance-payment proposition that allows businesses to top up their energy credit.
SmartestEnergy Business positions this particularly towards:
hospitality businesses
new businesses
businesses wanting greater payment control
Gas prices depend on the individual supply, so don’t assume the supplier offering the lowest electricity quote will necessarily also provide the lowest gas quote.
Compare each fuel and the combined annual cost.
SmartPay Business Energy
SmartPay is essentially a pay-as-you-go approach for eligible businesses – rather than simply receiving a conventional monthly bill, the business can pay for energy credit in advance.
Top-ups can be made:
online
by phone
through Direct Debit
SmartestEnergy Business describes SmartPay as useful for businesses with unpredictable cash flow and can also provide an option for some businesses without a conventional credit rating.
Prepayment changes how and when you pay for energy; it doesn’t automatically mean the underlying energy price is cheaper than every conventional contract.
Compare the actual rates.
SmartestEnergy Business Smart Meters
Smart meters have been a significant part of SmartestEnergy Business’s proposition since its Dual Energy days.
The supplier offers smart-meter technology to help provide:
automatic meter readings
more accurate billing
less reliance on estimated bills
better consumption information
SmartestEnergy Business promotes free smart-meter installation as part of applicable products.
However, technical eligibility and installation arrangements can vary by site.
Check what meter is required for your specific contract and premises.
SmartWeb Online Account Management
SmartWeb is SmartestEnergy Business’s online account-management service and customers can use it to manage aspects of their energy account.
The electricity proposition also includes an energy-monitoring tool that can provide consumption information in:
half-hourly intervals
daily reports
weekly reports
monthly reports
This can help businesses identify:
unusual energy use
overnight consumption
seasonal changes
differences between sites
Consumption data becomes most valuable when the business actually uses it to identify and reduce avoidable energy use.
See our commercial energy efficiency guide .
SmartestEnergy for Small Businesses
SmartestEnergy Business is particularly relevant to the SME market – their current quote journey separates customers broadly between:
small or micro businesses
and
medium-large businesses.
For its online journey, it currently describes a small/micro business as having annual spend up to £30,000 or consumption up to:
100,000 kWh electricity
or
293,000 kWh gas.
These are routing criteria used by SmartestEnergy Business and should not be confused with every regulatory definition of a small business.
For smaller companies, useful products include:
SmartFix Standard
SmartFix Renewable
SmartFix Zero
SmartTracker
Compare Small Business Energy Prices
SmartestEnergy Business Low User Tariff
SmartestEnergy Business also has a Low User product- it describes this as designed for businesses with annual usage typically below:
5,000 kWh.
At very low consumption levels, suppliers can sometimes be unable to offer the same discounted contract rates available to higher-usage customers.
The Low User product is variable, which means prices can change.
If your business consumes very little electricity, compare the Low User product with SmartFix Zero and competing suppliers particularly carefully.
Standing charges can have a disproportionate effect on the annual cost of very low-use premises.
SmartestEnergy for Medium & Large Businesses
SmartestEnergy Business also serves medium and larger organisations – their current customer journey includes businesses with:
annual spend over £30,000
or
more than 100,000 kWh electricity consumption.
The wider SmartestEnergy group also operates a dedicated commercial and industrial energy proposition for significantly larger users.
SmartestEnergy Limited currently describes smaller-business customers in its C&I routing as businesses below approximately:
300,000 kWh annual volume
or
£50,000 annual spend.
Businesses above that level may therefore find the wider SmartestEnergy C&I proposition more relevant.
The correct SmartestEnergy route depends on the scale and complexity of the organisation.
SmartestEnergy for Multi-Site Businesses
SmartestEnergy Business explicitly supports businesses with multiple sites and supply points which can be useful for:
retail groups
hospitality businesses
care groups
property portfolios
office groups
franchises
When comparing multi-site contracts, consider:
total portfolio consumption
number of meters
contract end dates
meter types
site-level consumption
reporting requirements
billing arrangements
Don’t assume every site necessarily needs the same tariff structure.
A seasonal low-use site may have very different requirements from a high-consumption location.
SmartestEnergy Business Renewable Energy
Renewable energy is an important part of the SmartestEnergy proposition.
SmartestEnergy Business offers renewable electricity products intended to help businesses reduce the carbon impact associated with purchased electricity and their renewable products are independently verified by the Carbon Trust.
The wider SmartestEnergy group also offers more sophisticated renewable procurement products for larger organisations, including:
Traceable Renewable Supply
Standard Renewable Supply
Natural Renewable Supply
Specific Renewable Supply
Corporate PPAs
This creates a pathway from straightforward SME renewable electricity through to sophisticated corporate renewable procurement.
Make sure you compare the product relevant to your organisation rather than assuming all SmartestEnergy renewable products work in the same way.
SmartestEnergy Business Pass-Through Charges
Business energy bills contain more than the wholesale cost of electricity or gas.
SmartestEnergy Business explains that non-energy or pass-through costs can account for approximately:
40-60% of an energy bill
depending on meter type and business location.
These costs can include charges associated with the networks and wider energy system – this became particularly relevant in 2026 because of changes to electricity Transmission Network Use of System charges.
SmartestEnergy Business says newly priced contracts, including renewals, from mid-February 2026 incorporate the latest applicable 2026/27 TNUoS increases into tariff pricing.
Businesses comparing fixed energy contracts should therefore ask exactly which costs are fixed and which can still be passed through or adjusted.
A tariff being described as “fixed” doesn’t necessarily mean every component of the final bill can never change.
SmartestEnergy Business Deemed Rates
A deemed contract can arise when:
a business moves into premises already supplied by SmartestEnergy Business without agreeing a new contract
a customer is using energy but has never agreed a contract with the supplier
SmartestEnergy Business publishes deemed rates for electricity and gas as required under its supply licences.
These are variable rates.
Deemed rates should not be confused with the personalised price available through SmartFix or another negotiated contract.
If you discover that your business is on a deemed tariff:
Confirm your current rate.
Check your annual consumption.
Request a contracted quote.
Compare other suppliers.
Switch or contract where appropriate.
See our deemed business energy rates guide .
SmartestEnergy Business Out-of-Contract Rates
Existing customers can become out of contract if they reach the end of their contracted period without:
renewing
switching supplier
SmartestEnergy Business states that these customers are billed on its variable SmartFlex rates.
Because the price is variable, it can change.
Don’t allow an existing fixed contract to expire without checking what rate will apply next.
Compare renewal pricing before the contract end date.
See our out-of-contract business energy rates guide .
Switching to SmartestEnergy Business
SmartestEnergy Business offers an online quotation journey through SmartSwitch, so before requesting a quote, gather:
a recent energy bill
business address
annual electricity consumption
annual gas consumption
MPAN
MPRN
meter details
current supplier
current contract end date
Then compare SmartFix Standard vs SmartFix Renewable vs SmartFix Zero vs SmartTracker where applicable.
The most appropriate product depends on your:
energy usage
budget requirements
appetite for variable prices
renewable-energy requirements
meter eligibility
See our business energy switching guide .
What Do You Need for a SmartestEnergy Business Quote?
For an accurate comparison, have the following available:
business name
supply address
postcode
MPAN
MPRN where applicable
annual electricity usage
annual gas usage
meter type
current supplier
contract end date
number of sites
Your MPAN identifies an electricity supply.
Your MPRN identifies a gas supply.
See our MPAN and MPRN guide .
SmartestEnergy Business Contract Renewal
If your SmartestEnergy Business contract is approaching its end date, compare the renewal offer before accepting it.
Check:
new unit rate
new standing charge
contract duration
product type
renewable credentials
pass-through charges
estimated annual cost
Also consider whether your requirements have changed.
For example:
Previously fixed → would SmartTracker now suit your risk appetite?
Standard electricity → do you now need renewable electricity?
Low or seasonal consumption → are you eligible for SmartFix Zero?
Business growth → has your consumption moved you into a different product segment?
Then compare the renewal against other suppliers.

SmartestEnergy Business vs TotalEnergies
Both suppliers can support commercial energy users, but TotalEnergies extends particularly strongly into major industrial and commercial procurement.
SmartestEnergy Business has a clear SME proposition with products designed around certainty + renewable energy + zero standing charges + market tracking.
TotalEnergies can become particularly relevant where a major organisation needs more sophisticated procurement structures.
For a typical SME, compare the actual electricity and gas quotes.
For a major commercial user, compare the wider procurement capability as well.
See our TotalEnergies Business Energy review .
SmartestEnergy Business vs Drax
These suppliers have notably different propositions.
SmartestEnergy Business supplies:
electricity + gas
and has a particularly accessible SME product range.
Drax Energy Solutions currently focuses much more heavily on business electricity + renewable supply + large-user flexible procurement.
Drax Flex products are designed for businesses consuming millions of kWh annually.
SmartFix Zero, by contrast, is specifically relevant to eligible electricity users consuming between 1,500 and 25,000 kWh annually.
This makes the two suppliers relevant to very different energy-consumption profiles in parts of their respective ranges.
See our Drax Business Energy review .
SmartestEnergy Business Pros & Cons

disadvantages
No universal contracted unit rate is published for every business
SmartFix Zero has specific meter and consumption eligibility requirements
Zero standing charge does not automatically mean the lowest annual bill
SmartTracker exposes businesses to changing market prices
Very low users may not qualify for the same discounted contract pricing as larger consumers
SmartestEnergy Business and SmartestEnergy Limited propositions can initially be confusing
Some non-energy costs can be passed through or adjusted depending on the contract
Businesses still need to compare renewal pricing against the wider market
Our View: When SmartestEnergy Business Makes Sense
SmartestEnergy Business stands out in this supplier cluster because it offers several genuinely different ways for an SME to buy energy rather than simply presenting one standard fixed tariff.
There are four particularly clear use cases.
Business wanting certainty → SmartFix Standard
Business prioritising renewable electricity → SmartFix Renewable
Low-use or seasonal electricity customer → investigate SmartFix Zero
Business comfortable following market prices → SmartTracker
SmartFix Zero is probably the most distinctive proposition.
The eligibility range of: 1,500–25,000 kWh annually means it is aimed squarely at smaller electricity users.
We would never recommend choosing SmartFix Zero solely because the standing charge is £0.
Calculate the annual cost.
SmartestEnergy Business is also more broadly applicable to SMEs than Drax’s current proposition because it offers both electricity and gas and caters directly to smaller consumption levels.
For substantially larger organisations, the distinction between SmartestEnergy Business and SmartestEnergy Limited becomes important.
The wider SmartestEnergy C&I business offers much more sophisticated:
flexible procurement
renewable supply
Corporate PPAs
energy trading
Overall, SmartestEnergy Business is particularly worth comparing where a company wants:
SME-focused energy + multiple tariff structures + renewable options + smart-meter technology.
But the deciding factor should still be:
total annual cost + contract terms + product fit.
