Shell Energy vs E.ON: comparing commercial tariffs and features to help you choose for your business

Shell Energy and E.ON both supply gas and electricity to UK businesses, but their products are aimed at somewhat different customers.

E.ON Next offers relatively straightforward one, two and three-year contracts to small and medium-sized businesses. It also provides smart meters, the E.ON Optimum consumption platform, commercial solar panels, battery storage and electric vehicle charging. Larger users can access sophisticated fixed and flexible procurement through npower Business Solutions, which forms part of the E.ON group.

Shell Energy supplies businesses ranging from small enterprises spending less than £50,000 a year to major industrial customers with multimillion-pound energy portfolios. Its offering includes fixed contracts, pass-through products, flexible wholesale purchasing, renewable gas and electricity, corporate power purchase agreements and integrated energy infrastructure.

For a typical SME, E.ON is likely to offer the more accessible all-round package. Its business proposition is simpler, its gas standing charge is considerably lower and its energy-monitoring, solar and electric vehicle services are clearly packaged for smaller organisations.

Shell Energy may be better for renewable procurement and complex commercial requirements. Its fixed electricity products include 100% renewable electricity, while larger customers can select flexible contracts lasting as long as five years and obtain renewable gas backed by Renewable Gas Guarantees of Origin.

The price comparison is not straightforward. Shell’s published deemed electricity rates have lower headline unit and standing charges, but major network costs are passed through separately. Shell’s deemed gas rate can be cheaper for moderate and high consumption, whereas its extended-supply gas tariff is substantially more expensive than E.ON’s deemed rates.

Is Shell Energy still operating in the UK?

Shell Energy remains active as a UK business energy supplier.

Shell sold its UK domestic electricity and gas retail operation to Octopus Energy in December 2023. The transfer of domestic Shell Energy customers was completed in 2024, meaning households previously supplied by Shell now receive their energy from Octopus.

That sale did not close Shell’s commercial energy-supply operation. Shell Energy continues to supply electricity, gas and energy-management services to UK businesses, including small companies, multi-site organisations and major industrial users.

This distinction is important because online reviews or articles describing Shell Energy as closed often refer only to the former domestic retail business.

Shell defines small businesses broadly as organisations spending less than £50,000 a year on energy. Medium-sized organisations spend between £50,000 and £10 million, while major industrial and commercial customers can access Shell’s most sophisticated flexible products.

E.ON Next generally serves organisations using no more than 100,000 kWh of electricity or 293,000 kWh of gas annually. Larger users are directed to npower Business Solutions.

Which is cheaper: Shell Energy or E.ON?

Neither supplier publishes universal fixed-contract prices. A business quotation can depend on:

• Annual electricity and gas consumption
• Meter profile and settlement type
• Distribution region
• Number of premises
• Agreed electricity capacity
• Contract duration
• Contract start date
• Payment method
• Credit history
• Renewable-energy requirements
• Treatment of network and government charges
• Broker commission

The clearest public comparison uses deemed and variable prices. These rates normally apply when a business occupies premises without having agreed a formal supply contract.

Shell also publishes separate extended-supply rates. These can apply when a Shell fixed contract expires and the customer continues taking energy without arranging a replacement agreement.

This means a Shell customer’s out-of-contract price depends on why the site is not covered by a fixed agreement. Shell’s deemed and extended-supply tariffs differ substantially.

Shell Energy vs E.ON electricity prices

The latest Shell rates took effect on 1 July 2026. E.ON’s deemed-contract webpage also identifies its current documents as effective from 1 July 2026, although the SME price cards inside the E.ON documents are dated 10 April 2026. Businesses should confirm the rate applying to their account before making a financial decision.

Non-half-hourly electricity rates

Supplier and tariff	Unit rate	Standing charge
Shell deemed electricity	28.312p per kWh	168p per day
Shell extended-supply electricity	35.474p per kWh	168p per day
E.ON deemed electricity	36.5p to 41.1p per kWh	300p per day

On the headline figures, Shell appears considerably cheaper. However, Shell’s published electricity rates exclude several important network costs.

Shell passes through prevailing charges including:

• Distribution Use of System capacity charges
• Distribution fixed charges
• Reactive-power charges
• Transmission Network Use of System charges
• Other applicable meter or site-specific network costs

The Shell unit rate and standing charge therefore do not represent the complete electricity bill.

E.ON’s published SME price card does not present the same explicit network-cost exclusion beside its unrestricted unit rate. Nevertheless, businesses should still check the contractual treatment of taxes, regulatory costs, capacity charges and other third-party costs before comparing totals.

Example annual electricity cost

The following illustration assumes annual electricity consumption of 20,000 kWh through a standard unrestricted meter.

Supplier and tariff	Unit-rate cost	Standing charge	Headline annual total
Shell deemed	£5,662.40	£613.20	£6,275.60 plus network pass-through costs
Shell extended supply	£7,094.80	£613.20	£7,708.00 plus network pass-through costs
E.ON – lowest-priced region	£7,300.00	£1,095.00	£8,395.00
E.ON – highest-priced region	£8,220.00	£1,095.00	£9,315.00

Shell’s headline deemed total is £2,119 to £3,039 below E.ON’s published total before Shell’s separately billed network charges are added.

Shell’s extended-supply headline total is £687 to £1,607 below E.ON before those pass-through charges.

A business should not conclude that Shell is cheaper from this table alone. The fair comparison is a fully loaded annual quotation showing every pass-through, capacity, metering and network charge.

Electricity price winner

There is no definitive winner from the published electricity rates.

Shell has the lower unit rate and standing charge, but its separately passed-through network costs prevent a direct like-for-like comparison.

E.ON provides a more immediately understandable regional price schedule. Shell may still produce the lower total cost, particularly for sites with favourable network characteristics, but this can only be established from a complete annual forecast.

Shell Energy vs E.ON gas prices

Shell’s gas tariff structure differs significantly from E.ON’s.

Supplier and tariff	Annual consumption	Unit rate	Standing charge
Shell deemed gas	1–73,200 kWh	7.482p per kWh	446p per day
Shell deemed gas	73,201–732,000 kWh	7.680p per kWh	1,586p per day
Shell deemed gas	More than 732,000 kWh	7.571p per kWh	2,646p per day
Shell extended supply	1–73,200 kWh	11.044p per kWh	548p per day
Shell extended supply	73,201–732,000 kWh	11.242p per kWh	1,688p per day
Shell extended supply	More than 732,000 kWh	11.133p per kWh	2,747p per day
E.ON deemed gas	Typical SME supply	11.8p to 12.6p per kWh	175p per day

Shell’s deemed gas unit price is substantially below E.ON’s. However, Shell has a much higher standing charge.

For a small gas site, Shell charges 446p per day, compared with E.ON’s 175p. Shell’s daily charge rises sharply when annual consumption exceeds 73,200 kWh.

Example annual gas cost

The following example assumes annual gas consumption of 30,000 kWh.

Supplier and tariff	Unit-rate cost	Standing charge	Estimated annual total
Shell deemed	£2,244.60	£1,627.90	£3,872.50
Shell extended supply	£3,313.20	£2,000.20	£5,313.40
E.ON – lowest regional rate	£3,540.00	£638.75	£4,178.75
E.ON – highest regional rate	£3,780.00	£638.75	£4,418.75

At 30,000 kWh:

• Shell’s deemed gas tariff is approximately £306 to £546 cheaper than E.ON.
• E.ON is approximately £895 to £1,135 cheaper than Shell’s extended-supply tariff.

This illustrates why the customer’s contractual status matters. A new occupier on Shell’s deemed tariff may obtain a relatively competitive result, while an existing Shell customer moved onto extended-supply rates could pay substantially more.

Gas crossover point

Shell’s lower deemed gas unit rate begins to outweigh its higher standing charge at approximately 19,000 to 23,000 kWh of annual consumption, depending on the E.ON regional rate.

This means:

• E.ON can be cheaper for a very low-consumption gas site.
• Shell’s deemed tariff can become cheaper as consumption rises.
• E.ON is likely to be cheaper than Shell’s extended-supply tariff at ordinary SME consumption levels.

Gas price winner: dependent on tariff status

Shell has the stronger deemed unit rate, while E.ON has the much lower standing charge and is considerably cheaper than Shell’s extended-supply product in the example.

Half-hourly electricity comparison

Larger electricity customers are often settled half-hourly and face additional capacity, metering and data charges.

Shell’s published rates effective from 1 July 2026 are:

Shell half-hourly tariff	Unit rate	Standing charge
Deemed	27.919p per kWh	217p per day
Extended supply	35.081p per kWh	217p per day

Availability, capacity, reactive-power and other applicable network charges are passed through separately.

E.ON’s half-hourly deemed prices vary by distribution region, voltage, capacity and charging band. Its complete annual cost can include:

• Unit rates
• Daily standing charges
• Agreed capacity
• Excess-capacity charges
• Reactive-power charges
• Meter operator charges
• Data collection and aggregation
• Distribution charges
• Transmission charges

A half-hourly business should obtain a full annual forecast rather than comparing the headline unit rates alone.

Shell may look less expensive at unit-rate level, but the final result depends heavily on its passed-through network charges and the characteristics of the site.

Shell Energy contract options

Shell offers different products based on the size and complexity of the business.

Shell fixed-price contracts

Shell’s conventional fixed product is primarily aimed at businesses spending less than £50,000 a year on energy.

Features include:

• Contract terms from one to 36 months
• An all-inclusive quoted rate
• 100% renewable electricity
• Online account management
• Smart or advanced meter support
• Options for gas and electricity

Shell describes the price as agreed upfront, although its terms allow changes where laws, regulation or certain third-party charges alter beyond its reasonable control. Businesses should therefore review the pass-through and variation clauses rather than relying solely on the term “fixed”.

Shell pass-through contracts

Shell’s pass-through product is aimed mainly at half-hourly customers spending more than £50,000 annually.

The business can fix its commodity cost while allowing selected non-commodity charges to be billed at their prevailing rates. This can avoid the risk premium a supplier may add when guaranteeing uncertain industry charges.

Pass-through contracts can provide:

• Greater bill transparency
• Separate visibility of wholesale and industry costs
• Reduced supplier risk premiums
• Greater exposure to increases in network and policy charges
• Group billing and flexible payment arrangements for multi-site customers

This product is more suitable for organisations that understand non-commodity charges and can tolerate changes in their bills.

Shell flexible purchasing

Shell offers two principal flexible electricity structures for major customers.

Flex Shape is generally available for contracts lasting 12 to 36 months. It allows the supplier and customer to manage the shape of expected demand while giving the business access to wholesale purchasing opportunities.

Block and Index can last from 12 to 60 months. The customer purchases blocks of electricity in advance, while residual consumption is settled against an agreed market index.

Shell generally positions these products towards businesses spending more than £1 million annually on electricity. Both can include 100% renewable electricity.

E.ON contract options

E.ON Next SME contracts

E.ON Next offers small and medium-sized businesses fixed contracts lasting:

• One year
• Two years
• Three years

Selected fixed electricity tariffs include 100% renewable electricity. Customers also receive online account management and access to dedicated Energy Specialists.

E.ON’s standard SME proposition is less complex than Shell’s range. This can make it more accessible to shops, offices, hospitality businesses and smaller property portfolios that want predictable rates without actively managing wholesale purchases.

E.ON large-business contracts

Larger users can access npower Business Solutions.

Its fixed products include:

• Fixed Certainty
• Fixed Commodity
• Fixed Choice
• MultiPurchase
• Market Tracker

Fixed Certainty is designed to fix wholesale, network and environmental charges included in the contract. Fixed Commodity fixes the wholesale element while allowing specified third-party charges to pass through. MultiPurchase lets customers buy expected consumption in several transactions instead of fixing everything on one date.

Flexible products include:

• Flex Streamline
• Fast Flex
• Flex Innovate
• Renewable flexible contracts
• Portfolio management and market reporting

Some flexible products are aimed at organisations consuming more than 1 GWh annually, although suitability depends on the customer’s metering, portfolio and risk-management requirements.

Which provides better price certainty?

For a conventional SME, both suppliers offer fixed products, but the contract wording remains important.

Shell describes its standard fixed product as an all-inclusive price agreed upfront. However, its terms allow adjustments for certain legal, regulatory and third-party cost changes.

E.ON Next also offers fixed tariffs, but businesses should confirm which non-commodity charges are guaranteed. For larger customers, npower Business Solutions provides more explicit choices between fixing and passing through network and environmental charges.

Price-certainty winner: E.ON for larger organisations

E.ON’s Fixed Certainty structure provides a clearly defined route for major customers seeking protection from both wholesale and specified non-commodity cost changes.

For SMEs, the result depends on the exact Shell or E.ON contract rather than the supplier name alone.

Renewable electricity and gas

Shell renewable energy

Shell’s fixed and flexible electricity products can include electricity matched with 100% renewable generation through Renewable Energy Guarantees of Origin.

Businesses can also request supplies linked to particular generation technologies, projects or locations. Shell additionally provides renewable gas supported by Renewable Gas Guarantees of Origin and can develop corporate power purchase agreements for larger organisations.

Shell’s disclosed electricity fuel mix for April 2024 to March 2025 was:

Energy source	Shell Energy fuel mix
Renewables	71%
Natural gas	22%
Coal	4%
Other fuels	2%
Nuclear	1%

Shell reported carbon intensity of 141 grams of carbon dioxide per kWh across its overall disclosed supply portfolio. Dedicated renewable products are separately evidenced using renewable certificates.

E.ON renewable energy

E.ON Next offers 100% renewable electricity on selected fixed business tariffs rather than every standard contract.

For larger users, npower Business Solutions offers:

• UK Business Renewable
• UK Renewable Pure
• UK Renewable Pure Plus
• Corporate power purchase agreements
• Renewable fixed and flexible contracts

UK Renewable Pure is sourced from wind, solar and hydro generation. Pure Plus offers greater traceability by matching the customer’s consumption with known UK generation partners. Corporate PPAs are generally designed for substantial half-hourly users and can connect an organisation contractually with a specific renewable project.

E.ON’s overall disclosed electricity mix for April 2024 to March 2025 was:

Energy source	E.ON fuel mix
Natural gas	51.5%
Renewables	31.3%
Coal	10.2%
Other fuels	4.3%
Nuclear	2.7%

E.ON reported portfolio carbon intensity of 331 grams of carbon dioxide per kWh. The figures include customers on both conventional and dedicated renewable products.

Renewable-energy winner

Shell has the advantage for conventional renewable business supply.

Its fixed electricity proposition includes 100% renewable electricity, its overall disclosed fuel mix contains a higher renewable share and it offers a clearly defined RGGO-backed renewable gas option.

For complex corporate PPAs, the comparison is closer. Both suppliers provide traceable renewable procurement structures for major energy users.

Smart meters and energy monitoring

Shell smart meters and My Account

Shell provides smart and advanced meters to eligible businesses without a separate installation charge.

From October 2024, customers with compatible meters have been able to access their half-hourly consumption data through Shell Energy My Account. The service provides:

• Up to 12 months of consumption data
• Downloadable usage information
• Automatic meter readings
• Reduced reliance on estimated bills
• Analysis across several premises
• Visibility of consumption patterns

This can help businesses identify overnight baseload, unusual peaks and differences between sites.

E.ON smart meters and Optimum

E.ON also installs eligible business smart meters without a separate installation charge. It reports having installed more than 160,000 smart meters for business customers.

E.ON Optimum is available without an additional subscription charge to eligible SME customers. It provides:

• Half-hourly consumption information
• Up to 12 months of downloadable data
• Year-on-year comparisons covering up to three years
• Benchmarking against comparable properties
• Energy-efficiency and sustainability guidance
• Remote access to gas and electricity information

The benchmarking and longer-term comparison functions make Optimum particularly useful for SMEs that want an accessible energy-management tool without purchasing specialist software.

Energy-monitoring winner: E.ON by a narrow margin

Both suppliers provide free consumption data to eligible customers. E.ON Optimum adds structured benchmarking and longer-term year-on-year comparisons, while Shell’s platform is well suited to downloading and analysing multi-site half-hourly data.

Commercial solar, batteries and energy infrastructure

E.ON has a clearly packaged solar and battery proposition for small and medium-sized businesses.

Its systems typically range from 15 kW to 100 kW, although larger installations can be developed. Services include:

• Solar-panel installation
• Battery storage
• Structural roof assessments
• Distribution Network Operator applications
• Three-dimensional system design
• Return-on-investment forecasts
• Monitoring software
• Multi-site designs

E.ON also provides workplace and public electric vehicle chargers, ranging from wall-mounted units to ultra-rapid equipment.

Shell takes a more integrated and bespoke approach. Its energy solutions can include:

• On-site solar generation
• Battery storage
• Microgrids
• Low-carbon heating
• Electric vehicle infrastructure
• Flexible generation
• Battery optimisation
• Trading and route-to-market services

This broader proposition is more likely to appeal to industrial facilities, large property portfolios, logistics businesses and organisations seeking to coordinate several energy assets.

Packaged SME solar winner: E.ON

Integrated industrial energy winner: Shell

Customer service comparison

Shell separates support according to annual energy expenditure.

Businesses spending less than £50,000 can obtain quotations and manage their accounts through Shell’s small-business channels. Larger organisations are directed to specialist commercial teams and account managers. Shell also promotes support from UK-based energy specialists.

E.ON’s business telephone service operates:

• 9am to 5pm Monday to Thursday
• 9am to 4pm on Friday

Customers can also use email, WhatsApp and online account services. Emergency support remains available outside ordinary contact-centre hours.

Both suppliers operate formal complaint procedures. Eligible microbusinesses and small-business customers may refer unresolved complaints to the Energy Ombudsman once the applicable eight-week or deadlock requirements have been met.

Trustpilot ratings

Supplier profile	TrustScore	Number of reviews
Shell Energy UK business	4.7 out of 5	Approximately 179
E.ON Next	4.5 out of 5	Approximately 211,000

Shell has the higher score and its profile relates directly to business energy. However, the sample is very small, so a modest number of reviews can significantly alter the rating. Shell uses a paid Trustpilot profile and invites reviews.

E.ON’s score is based on a vastly larger sample but covers its wider customer base, which is dominated by domestic energy users. E.ON also invites reviews and reportedly responds to most negative submissions.

Review winner: Draw

Shell has the more relevant business-only profile, while E.ON has the much stronger sample size. Neither score provides a perfect measure of the service a particular business account will receive.

Final verdict: Shell Energy vs E.ON

E.ON is the better all-round supplier for a typical small or medium-sized business.

Its one, two and three-year contracts are relatively straightforward, its gas standing charge is substantially lower and E.ON Optimum provides accessible consumption analysis. E.ON also has a clearly structured commercial solar, battery and electric vehicle proposition.

The route into npower Business Solutions gives growing organisations access to longer contracts, flexible purchasing, renewable products and corporate PPAs without moving outside the wider E.ON group.

Shell Energy is particularly strong for renewable energy and complex procurement.

Its fixed electricity products include 100% renewable electricity, while renewable gas, pass-through contracts, flexible purchasing and integrated energy infrastructure make it a credible option for major industrial and multi-site customers.

The published price comparison produces a mixed result:

• Shell has much lower headline deemed electricity rates, but separately passes through important network charges.
• Shell’s deemed gas tariff can be cheaper at moderate and high consumption.
• E.ON can be cheaper for low-consumption gas sites because of its lower standing charge.
• E.ON is substantially cheaper than Shell’s extended-supply gas tariff in the 30,000 kWh example.
• A fully loaded annual electricity forecast is essential before declaring either supplier cheaper.

For a conventional SME, E.ON offers the more balanced combination of simplicity, technology and supporting services.

For a business prioritising renewable gas, 100% renewable fixed electricity, flexible purchasing or an integrated industrial energy strategy, Shell Energy may be the stronger choice.
