EDF and TotalEnergies Gas & Power are two of the UK’s largest business energy suppliers. Both provide electricity, gas, renewable-energy options, smart meters, commercial solar and sophisticated contracts for larger organisations.
Their main strengths are different.
EDF offers relatively straightforward small-business tariffs, including fixed contracts lasting between one and four years, a zero-standing-charge option and a dedicated renewable electricity tariff. Larger companies can choose fully fixed, partly fixed or flexible energy procurement, together with renewable, nuclear-backed or mixed-source electricity.
TotalEnergies supplies more than 200,000 UK business sites. Its large-business range includes Fixed Price, Fixed-Flexi, Baseload and Fully Traded contracts. It also offers a zero-standing-charge product for qualifying small businesses and several renewable electricity options.
EDF may be the stronger choice for a company wanting:
- a simple small-business tariff;
- a fixed contract lasting up to four years;
- nuclear-backed zero-carbon electricity;
- a published small-business export payment;
- conventional fully fixed procurement; or
- an integrated solar, battery and EV-charging package.
TotalEnergies may be more attractive where the company wants:
- a large-business contract lasting up to five years;
- sophisticated wholesale purchasing;
- a dedicated Baseload or Fully Traded arrangement;
- renewable electricity excluding biomass;
- generator Power Purchase Agreements;
- flexible treatment of non-energy charges; or
- a zero-standing-charge tariff with clearly published eligibility rules.
Neither company is universally cheaper. Business rates depend on the meter, location, annual consumption, demand pattern, credit profile, contract dates and treatment of third-party costs.

Which businesses can use EDF or TotalEnergies?
EDF generally directs companies using less than 100MWh of electricity or 300MWh of gas annually towards its small-business service. Companies above those levels are normally handled by EDF Large Business.
TotalEnergies supplies small companies, industrial users, public-sector organisations, multi-site businesses and renewable generators. It states that it supplies more than 200,000 sites across the UK.
| Example business | Annual electricity consumption | Potentially suitable option |
|---|---|---|
| Independent shop | 12,000kWh | Fixed or zero-standing-charge tariff |
| Small office | 40,000kWh | Small-business contract from either supplier |
| Restaurant | 120,000kWh | Tailored or large-business route |
| Hotel | 400,000kWh | Multi-site or large-business contract |
| Manufacturer | 2GWh | Fixed, Fixed-Flexi or block purchasing |
| National retailer | 10GWh | Flexible or fully traded contract |
| Business wanting nuclear-backed power | Varies | EDF |
| Business wanting renewable-only supply | Varies | Either supplier |
| Renewable generator | Project-dependent | EDF or TotalEnergies PPA |
Eligibility can also depend on:
- meter type;
- half-hourly demand;
- electricity voltage;
- available capacity;
- payment history;
- creditworthiness;
- number of premises; and
- the requested contract start date.
Which supplier is cheaper?
There is no single EDF-versus-TotalEnergies business rate.
A commercial quotation normally depends on:
- the electricity MPAN or gas MPRN;
- postcode and distribution region;
- annual consumption;
- meter profile;
- half-hourly demand pattern;
- agreed electricity capacity;
- contract start date;
- contract duration;
- number of locations;
- payment method;
- credit risk;
- renewable-product selection; and
- treatment of network and government charges.
The expected annual cost should include:
Annual consumption multiplied by the unit rate
Plus:
- the daily standing charge multiplied by 365;
- electricity-capacity charges;
- metering and data costs;
- network charges;
- environmental and government levies;
- VAT;
- Climate Change Levy where applicable; and
- any broker commission.
Export payments and other credits should then be deducted.
How unit-rate differences affect annual costs
| Annual consumption | Value of 0.5p/kWh | Value of 1p/kWh | Value of 3p/kWh | Value of 5p/kWh |
|---|---|---|---|---|
| 10,000kWh | £50 | £100 | £300 | £500 |
| 25,000kWh | £125 | £250 | £750 | £1,250 |
| 50,000kWh | £250 | £500 | £1,500 | £2,500 |
| 100,000kWh | £500 | £1,000 | £3,000 | £5,000 |
| 250,000kWh | £1,250 | £2,500 | £7,500 | £12,500 |
| 1GWh | £5,000 | £10,000 | £30,000 | £50,000 |
| 10GWh | £50,000 | £100,000 | £300,000 | £500,000 |
A business using 10GWh annually saves £100,000 for every 1p/kWh reduction in its average rate.
How standing charges affect annual costs
| Daily standing-charge difference | Annual difference per meter | Difference across ten meters |
|---|---|---|
| 25p | £91.25 | £912.50 |
| 50p | £182.50 | £1,825 |
| £1 | £365 | £3,650 |
| £2 | £730 | £7,300 |
| £5 | £1,825 | £18,250 |
Standing charges are particularly important for:
- seasonal businesses;
- vacant properties;
- commercial landlords;
- low-use premises;
- businesses with several meters; and
- sites that remain connected but consume little energy.
EDF small-business tariffs
EDF offers fixed small-business contracts lasting one, two, three or four years. Its standard Fixed for Business Online tariff includes fixed rates, payment by Direct Debit, online account management and smart-meter installation where eligible.
A fixed EDF tariff may suit a company that wants:
- predictable unit rates;
- predictable standing charges;
- protection from wholesale-price increases;
- fewer procurement exercises; and
- a relatively simple contract structure.
The disadvantage is that the business may remain tied to its agreed prices if wholesale energy costs subsequently fall.
EDF Fixed Renewable
EDF Fixed Renewable was introduced for small businesses in April 2026.
Each unit of electricity consumed is matched with a UK Renewable Energy Guarantee of Origin. The tariff is available with fixed terms of up to four years and supports zero market-based emissions reporting for purchased electricity.
The product may suit companies that want:
- renewable-only electricity;
- no nuclear allocation to the selected tariff;
- a conventional fixed contract;
- environmental reporting evidence;
- stronger tender credentials; or
- a clear renewable-energy claim.
EDF zero-standing-charge tariff
EDF offers a Fixed Online Zero Standing Charge tariff with terms of one, two, three or four years. Instead of paying a daily fee, the customer pays a higher rate for each unit of energy consumed.
This may benefit:
- seasonal attractions;
- cafés that close several days each week;
- farms;
- event venues;
- pop-up shops;
- low-use offices; and
- premises with irregular consumption.
It is not automatically cheaper. EDF explains that zero-standing-charge tariffs normally recover the missing fixed fee through a higher unit rate.
Break-even example
Suppose the conventional tariff has:
- a £2 daily standing charge; and
- a unit rate 2p/kWh below the zero-standing-charge tariff.
The annual standing charge is:
£2 multiplied by 365 = £730
The break-even level is:
£730 divided by £0.02 = 36,500kWh
Below 36,500kWh, the zero-standing-charge tariff may be cheaper.
Above 36,500kWh, the higher unit rate may cost more than the standing charge saved.
TotalEnergies small-business tariffs
TotalEnergies provides individually quoted electricity and gas contracts rather than publishing one national price table.
Its small-business service includes:
- gas;
- electricity;
- combined gas and electricity;
- smart and AMR meters;
- online account management;
- renewable electricity options; and
- access to business support teams.
A TotalEnergies quotation should clearly state:
- contract length;
- unit rate;
- standing charge;
- payment method;
- renewable premium;
- pass-through charges;
- early termination conditions;
- broker commission; and
- post-contract pricing.
TotalEnergies zero-standing-charge tariff
TotalEnergies launched its zero-standing-charge business product on 3 February 2026.
The tariff removes daily standing charges from qualifying gas and electricity contracts. The associated costs are instead recovered through the unit rate.
The published restrictions are:
| Supply | Restriction |
|---|---|
| Electricity | Non-half-hourly meters only |
| Gas | Maximum annual consumption of 500,000kWh |
| Maximum end date | Three years |
| Availability | New and renewing customers |
The tariff may suit businesses with low, variable or seasonal consumption.
EDF has the advantage where a business wants a zero-standing-charge fixed term lasting four years.
TotalEnergies may be attractive where its unit rate produces a lower overall cost for a qualifying gas or non-half-hourly electricity meter.
EDF vs TotalEnergies for small businesses
| Requirement | Likely stronger fit |
|---|---|
| Clearly published one-to-four-year terms | EDF |
| Four-year renewable tariff | EDF |
| Four-year zero-standing-charge tariff | EDF |
| Zero-standing-charge gas or electricity | Compare both |
| Conventional online quote | EDF |
| Individually tailored quote | TotalEnergies |
| Renewable electricity | Either |
| Nuclear-backed electricity | EDF |
| Simple published export tariff | EDF |
EDF’s public small-business proposition is easier to understand.
TotalEnergies may still offer the lower quotation, particularly for businesses whose consumption pattern suits its zero-standing-charge tariff.
EDF large-business fixed contracts
EDF offers a range of fixed and flexible contracts to larger organisations.
Fixed + Peace of Mind
Fixed + Peace of Mind is designed to provide high budget certainty.
It can fix:
- wholesale energy;
- eligible non-energy costs;
- delivery costs;
- new-generation costs; and
- EDF service charges.
This may suit organisations that value predictable expenditure more than the opportunity to benefit from falling prices.
Fixed + Standard
Fixed + Standard fixes the wholesale energy component and EDF’s service charge.
Forecast third-party costs can change during the agreement.
It may offer a lower opening price than Fixed + Peace of Mind, but provides less certainty.
Fixed + Energy Trading
Fixed + Energy Trading allows the company to purchase blocks of electricity through EDF’s trading desk.
EDF manages the remaining unpurchased volume.
This may suit a company that wants more control over when wholesale energy is purchased without operating a completely flexible contract.
EDF flexible procurement
EDF’s flexible contracts allow a business to decide:
- when energy is purchased;
- how much is bought in each transaction;
- which costs are fixed;
- which costs remain variable; and
- how much support is provided by EDF.
EDF also supplies market information and specialist energy procurement support.
Flexible purchasing can reduce the risk of fixing the entire forecast on one expensive date. However, it cannot guarantee that the business will obtain a lower price.
TotalEnergies large-business contracts
TotalEnergies publishes four principal large-business contract structures:
- Fixed Price;
- Fixed-Flexi;
- Baseload; and
- Fully Traded.
Fixed Price
Fixed Price provides a predetermined energy rate for an agreed term.
TotalEnergies states that contracts can run from a few months to five years.
This may suit a business that wants long-term certainty and limited involvement in wholesale-market purchasing.
Fixed-Flexi
Fixed-Flexi combines structured energy purchasing with periods of price certainty.
A business can purchase energy for:
- the complete contract;
- individual years;
- individual months; or
- another agreed period.
It may suit a business wanting some control over purchasing without assuming the complexity of a fully traded contract.
Baseload
The Baseload product allows a company to purchase expected underlying demand in advance.
TotalEnergies then manages or purchases the remaining volume under the agreed arrangement.
This may suit businesses with:
- stable base demand;
- predictable industrial loads;
- an experienced procurement team; or
- a desire to spread purchasing decisions over time.
Fully Traded
The Fully Traded product offers the greatest wholesale-market involvement.
It is intended for organisations with:
- accurate demand forecasts;
- flexible equipment;
- batteries or generation;
- experienced procurement staff; and
- the ability to accept market and imbalance risk.
TotalEnergies supports its large customers through an Energy Management Team that provides live or fair-market pricing, forward market analysis and transactional support.
EDF vs TotalEnergies for large businesses
| Requirement | Likely stronger fit |
|---|---|
| Conventional fully fixed contract | Compare both |
| Fixed contract lasting five years | TotalEnergies |
| Block purchasing through a trading desk | EDF |
| Structured annual or monthly purchasing | TotalEnergies Fixed-Flexi |
| Dedicated Baseload product | TotalEnergies |
| Fully traded market access | TotalEnergies |
| Flexible purchasing beyond five years | EDF |
| Nuclear-backed zero carbon | EDF |
| Traceable renewable supply | TotalEnergies |
| Conventional dual-fuel arrangement | Either |
TotalEnergies offers the more granular collection of named large-business procurement structures.
EDF offers a clearer progression from straightforward fixed pricing to block purchasing and flexible procurement.
Comparing the suppliers’ fuel mixes
The latest published fuel-mix disclosures cover the period from 1 April 2024 to 31 March 2025.
| Energy source | EDF | TotalEnergies |
|---|---|---|
| Coal | 4.2% | 9% |
| Natural gas | 21% | 45% |
| Nuclear | 54.8% | 2% |
| Renewables | 18.2% | 40% |
| Other fuels | 1.8% | 4% |
| Carbon emissions | 135g CO2/kWh | 292g CO2/kWh |
| Radioactive waste | 0.0038g/kWh | 0.0003g/kWh |
EDF had the lower reported carbon intensity, largely because nuclear power represented more than half of its supplier-wide mix.
TotalEnergies had the higher renewable share and much lower nuclear use, but it relied more heavily on natural gas and coal.
Which supplier has greener electricity?
The answer depends on how the business defines green energy.
| Environmental priority | Likely stronger fit |
|---|---|
| Higher supplier-wide renewable percentage | TotalEnergies |
| Lower supplier-wide carbon intensity | EDF |
| Lower gas and coal share | EDF |
| Lower nuclear share | TotalEnergies |
| Lower radioactive waste | TotalEnergies |
| Renewable-only fixed tariff | Either |
| Renewable product excluding biomass | TotalEnergies Pure Green |
| Nuclear-backed zero-carbon electricity | EDF |
| Choice between renewable and nuclear | EDF |
| PPA-linked renewable sourcing | TotalEnergies |
Neither supplier should be described as universally greener without identifying whether the priority is renewable content, fossil-fuel use, nuclear avoidance or carbon intensity.
TotalEnergies renewable electricity
TotalEnergies offers renewable electricity backed by UK renewable generation and certificates. Its sources can include wind, solar, anaerobic digestion and biomass.
Its Pure Green product uses:
- wind;
- solar; and
- hydroelectric generation.
Pure Green excludes biomass, fossil fuels and nuclear power.
This may appeal to a company that wants renewable-only electricity while excluding biomass.
EDF renewable and zero-carbon electricity
EDF offers businesses a choice between:
- renewable electricity;
- nuclear-backed zero-carbon electricity; and
- standard mixed-source electricity.
EDF’s renewable products are backed entirely by renewable generation and certificates.
Its Zero Carbon for Business product is backed by nuclear generation. Nuclear power produces no carbon dioxide at the point of generation, but it is not renewable and generates radioactive waste.
EDF therefore provides a clearer choice between renewable and nuclear-backed electricity.
Smart meters and energy data
TotalEnergies offers smart and AMR meters to eligible businesses.
Its TotalEnergies Insights portal provides:
- half-hourly consumption information;
- graphs showing usage trends;
- downloadable data;
- data covering electricity and gas; and
- access to up to 12 months of historical consumption.
EDF provides smart meters and Energy Hub to eligible small-business customers.
Energy Hub allows customers to review electricity consumption over hourly, daily, weekly and monthly periods.
| Data requirement | Likely stronger fit |
|---|---|
| Straightforward SME consumption charts | EDF Energy Hub |
| Half-hourly electricity and gas data | TotalEnergies Insights |
| Up to 12 months of historical data | TotalEnergies |
| Online billing and account management | Either |
| Wholesale trading information | TotalEnergies |
| EDF procurement reporting | EDF |
| Multi-site consumption analysis | Compare both |
Power Purchase Agreements
Both suppliers provide PPAs for renewable generators and corporate energy buyers.
TotalEnergies PPAs
TotalEnergies has worked with independent generators since 2008.
Its products range from fixed-price PPAs lasting six months to five years through to flexible agreements providing access to forward and day-ahead markets.
Its services can include:
- fixed export prices;
- market-linked prices;
- managed baseload;
- flexible trading;
- renewable certificates; and
- access to wholesale markets.
EDF PPAs
EDF provides:
- renewable-generator sourcing;
- balancing;
- shaping;
- sleeving;
- settlement;
- renewable certificates; and
- integration with the customer’s supply contract.
| PPA requirement | Likely stronger fit |
|---|---|
| Fixed generator PPA up to five years | TotalEnergies |
| Managed baseload generation | TotalEnergies |
| Flexible generator market access | TotalEnergies |
| Corporate supply integration | EDF |
| Balancing and sleeving | Either |
| Nuclear-backed supply alongside renewable PPA | EDF |
| Renewable-generator route to market | Either |
Commercial solar
TotalEnergies provides an end-to-end commercial solar service through SunPower and its installer network.
Available systems include:
- rooftop solar;
- ground-mounted solar;
- solar carports;
- small and large commercial installations;
- monitoring;
- maintenance;
- capital purchase;
- hire purchase; and
- Power Purchase Agreement funding.
EDF also provides solar, battery and EV-charging services to businesses. Its services include small-business sustainability support as well as larger commercial projects.
| Solar requirement | Likely stronger fit |
|---|---|
| Turnkey rooftop installation | Either |
| Ground-mounted solar | Either |
| Solar carport | TotalEnergies |
| Hire-purchase funding | TotalEnergies |
| Solar PPA | Either |
| Solar linked with a published export tariff | EDF |
| Multi-site commercial project | Compare both |
| Battery and EV integration | Either |
Solar export payments
EDF publishes small-business export tariffs paying up to 15p/kWh.
The business normally requires:
- qualifying renewable generation;
- a suitable export meter;
- no conflicting Feed-in Tariff export payment; and
- compliance with EDF’s tariff conditions.
Illustrative EDF export income
| Annual export | Income at 15p/kWh |
|---|---|
| 5,000kWh | £750 |
| 10,000kWh | £1,500 |
| 25,000kWh | £3,750 |
| 50,000kWh | £7,500 |
| 100,000kWh | £15,000 |
TotalEnergies’ public generation proposition focuses on negotiated PPAs and generator market access rather than an equivalent published flat small-business export rate.
EDF is therefore likely to be the simpler option for a small commercial solar system.
TotalEnergies may be more appropriate for a larger generator requiring a negotiated PPA or wholesale-market arrangement.
Electric vehicle charging
Both groups offer services connected with business EV charging.
EDF’s business sustainability proposition includes workplace, fleet and customer charging, together with solar and battery integration.
TotalEnergies also promotes EV-charging products as part of its business net-zero services, although its current UK business-energy website provides less detailed standard pricing than its solar pages.
| EV requirement | Likely stronger fit |
|---|---|
| Standard workplace charging | EDF |
| Fleet charging integrated with supply | EDF |
| Charging linked with solar | Either |
| Large infrastructure arrangement | Compare both |
| Charging linked with flexible procurement | TotalEnergies may suit |
| Simple small-business package | EDF |

Final verdict: EDF vs TotalEnergies
EDF and TotalEnergies are both credible business energy suppliers, but they are best suited to different procurement strategies.
EDF is likely to be the stronger choice where the company wants:
- a straightforward SME tariff;
- a one-to-four-year fixed contract;
- renewable-only electricity;
- nuclear-backed zero-carbon electricity;
- a conventional fully fixed large-business product;
- block purchasing through a trading desk;
- procurement horizons extending beyond five years;
- Energy Hub;
- a published solar-export payment;
- commercial solar maintenance; or
- packaged workplace and fleet charging.
TotalEnergies is likely to be stronger where the organisation wants:
- a large-business fix lasting up to five years;
- detailed control over non-commodity costs;
- Fixed-Flexi procurement;
- a dedicated Baseload contract;
- fully traded half-hourly access;
- zero-standing-charge SME energy;
- renewable electricity excluding biomass;
- PPA-linked traceability;
- renewable gas;
- advanced generator services; or
- funded rapid-charging infrastructure at a suitable site.
The environmental comparison has different winners depending on the measure used.
TotalEnergies had the higher renewable share:
- TotalEnergies: 40%;
- EDF: 18.2%.
EDF had the lower fossil-fuel share and lower reported carbon intensity:
- TotalEnergies: 54% gas and coal, with 292g CO₂/kWh;
- EDF: 25.2% gas and coal, with 135g CO₂/kWh.
EDF achieved its lower carbon figure largely through nuclear generation, which represented 54.8% of its mix.
TotalEnergies used considerably less nuclear power but relied more heavily on natural gas and coal.
At product level, both can provide 100% renewable electricity. EDF additionally offers a completely nuclear-backed zero-carbon product, while TotalEnergies provides several levels of renewable traceability and source selection.
The published deemed-rate comparison currently favours TotalEnergies on unit rates. However, it cannot establish which company will provide the cheaper negotiated contract.
A fair procurement exercise should ask both suppliers to quote for:
- the same meters and premises;
- identical annual consumption;
- the same contract start date;
- an equivalent term;
- all standing charges;
- fixed and pass-through components;
- capacity and metering costs;
- volume-tolerance provisions;
- equivalent environmental products;
- broker commission;
- solar export income;
- termination liability;
- renewal and default rates; and
- the complete projected annual cost.
For most businesses, the decision can be summarised as follows:
- choose EDF for simpler SME tariffs, source choice, conventional procurement, solar export payments and packaged technology;
- choose TotalEnergies for more advanced large-business contract structures, renewable gas, generator services and five-year fixing;
- compare both suppliers’ Zero Standing Charge products using a consumption break-even calculation;
- compare EDF Fixed + Peace of Mind with TotalEnergies Fixed Price where certainty matters;
- compare EDF Fixed + Energy Trading with TotalEnergies Fixed-Flexi or Baseload where staged purchasing matters;
- compare EDF’s SEG tariffs with a TotalEnergies PPA or third-party SEG supplier where generation is important; and
- select the supplier offering the lowest realistic annual cost after every standing, network, capacity, metering and environmental charge is included.
