ScottishPower vs E.ON Next: Which Energy Supplier Is Better in 2026?

Choosing between ScottishPower and E.ON Next involves more than comparing one electricity or gas rate. Both suppliers offer fixed, variable and smart tariffs, alongside EV charging, solar panels, batteries and heat-pump products.

E.ON Next is the stronger overall option for customer service, tracker tariffs, EV charging and premium solar export rates. ScottishPower is more attractive for customers who prioritise a 100% renewable disclosed fuel mix and simple half-price weekend rewards.

The cheapest option still depends on your postcode, annual usage, meter, payment method and eligibility for specialist tariffs. Compare personalized annual estimates before switching.

Quick answer

E.ON Next is the better overall choice for customer service, price-cap tracking, EV charging and premium solar export rates. ScottishPower may suit households that value Half-Price Weekends, EV Optimise or a dedicated renewable-electricity tariff. Neither supplier is always cheaper, so compare personalised quotes before switching.

ScottishPower vs E.ON Next—Detailed Comparison

The detailed comparison below looks at how ScottishPower and E.ON Next perform across pricing, tariffs, EV charging, renewable options, solar exports and customer service. It highlights the main strengths of each supplier and helps identify which one offers better value for different households.

1. Is ScottishPower or E.ON Next Cheaper?

Neither supplier is automatically cheaper for every household. Their standard variable tariffs are limited by the same Ofgem price cap, but regional rates, standing charges, fixed deals and smart-tariff eligibility can change the annual total.

From 1 July to 30 September 2026, Ofgem’s price cap is £1,862 a year for a typical dual-fuel household paying by Direct Debit. It is based on typical consumption rather than being a maximum bill.

These averages include 5% VAT and vary by region and payment method. A fair comparison must use identical consumption figures for both quotations.

ScottishPower Pricing

ScottishPower lists a Standard tariff, a one-year fixed tariff and Cap Tracker. Cap Tracker reduces standing charges by an amount equivalent to £15 per year for dual fuel compared with ScottishPower’s Standard tariff and has a £50 exit fee per fuel.

A fixed tariff protects its unit rates and standing charges during the fixed term, but it is not guaranteed to be cheaper if market prices later fall.

E.ON Next Pricing

E.ON Next offers Next Flex, one- and two-year fixes, Next Pledge and specialist time-of-use products. Next Pledge stays below the Ofgem price cap and advertises a £50 annual saving for typical dual-fuel consumption. The reduction is applied to unit rates, split as £25 per fuel. Lower-use households may save less.

Customers can move from Next Pledge to another E.ON Next tariff without an exit fee. Leaving E.ON Next costs £25 per fuel.

Pricing Verdict

E.ON Next has the stronger tracker deal, because its advertised typical reduction is greater. Fixed-tariff pricing remains quote-dependent, so neither supplier wins that category without personalised rates.

2. Who Has Better Fixed and Tracker Tariffs?

E.ON Next is better for customers who want prices to follow the cap while remaining below it. ScottishPower remains suitable for households wanting a conventional one-year fix or renewable electricity included in their tariff.

A fixed deal protects against increases but can become uncompetitive if prices fall. A tracker changes with its reference price. Next Pledge automatically falls when the Ofgem cap falls, while ScottishPower Cap Tracker offers a smaller discount through standing charges.

• Best price-cap tracker: E.ON Next
• Best fixed tariff: Depends on the personalised quote
• Best when prices may fall: E.ON Next Pledge
• Best for predictable rates: The cheaper available fixed deal

3. Which Supplier Is Better for EV Charging?

E.ON Next is currently better for most eligible EV owners because it provides a lower rate and a longer overnight window. ScottishPower EV Saver remains competitive for customers already using ScottishPower.

ScottishPower EV Saver charges 8.5p per kWh between midnight and 5am. The lower price applies to all household electricity consumed in that period. Customers need ScottishPower electricity, monthly Direct Debit and a compatible smart meter sending half-hourly readings. The tariff is backed by 100% green electricity.

E.ON Next Drive Smart charges 8p per kWh from midnight to 6am for the whole home. When its app schedules an eligible charge during the day, the same rate can also apply to household use during that charging period. Customers need a compatible EV and charger, smart meter, half-hourly consent, online account and monthly Direct Debit.

The standard Next Drive tariff charges 9p per kWh between midnight and 6am and may suit drivers without compatible smart equipment.

EV Verdict

E.ON Next wins EV charging. Its best rate is 0.5p lower and its overnight period lasts six hours rather than five. Compare daytime prices too, because higher peak consumption can offset overnight savings.

4. Which Supplier Is Greener?

ScottishPower has the stronger disclosed electricity fuel mix. For 1 April 2024 to 31 March 2025, ScottishPower reported 100% renewable electricity, while E.ON Next reported 31.3%.

Fuel-mix disclosures describe how suppliers account for electricity sold. Homes still receive electricity through the shared national grid rather than a physically separate renewable supply.

Green Energy Verdict

ScottishPower wins clearly for its disclosed fuel mix. E.ON Next offers renewable and smart products, but its company-wide mix contains substantially more fossil-fuel generation.

5. Who Pays More for Solar Exports?

E.ON Next offers the highest premium Smart Export Guarantee rate, while both suppliers provide a standard 6p per kWh option. Eligibility depends on the installer and whether the customer also buys electricity from that supplier.

ScottishPower’s rates are published on its solar page. E.ON Next’s premium and exclusive tariffs are fixed for 12 months, require a smart export meter and include additional conditions. Next Drive customers are excluded from the 13p Exclusive tariff.

Solar Export Verdict

E.ON Next wins on the highest rate, paying up to 17.5p per kWh compared with ScottishPower’s 15p. Customers who do not meet premium conditions receive the same 6p standard rate from either supplier.

6. Who Has Better Customer Service?

E.ON Next performs substantially better in the latest Citizens Advice comparison. It ranks third with 3.71 out of 5, while ScottishPower ranks tenth with 2.94.

ScottishPower performs slightly better for contact waiting time, but E.ON Next has stronger complaints and billing scores. The data covers January to March 2026; Citizens Advice expects the next update in September 2026.

Customer Service Verdict

E.ON Next wins customer service because its overall score is significantly higher, despite ScottishPower’s better waiting-time result.

7. Which Supplier Has Better Smart Rewards?

ScottishPower is better for simple weekend savings, while E.ON Next offers more advanced time-of-use and smart-equipment tariffs.

ScottishPower Power Saver provides Half-Price Weekends. Registered customers receive half-price electricity from 11am to 4pm on Saturday and Sunday, which can reward households that shift washing, cooking or charging into those hours.

E.ON Next offers Next Smart Saver, Next Drive, Next Drive Smart and Next Optimise. Smart Saver encourages use outside the 4pm–7pm peak. Next Optimise manages compatible solar batteries by charging when prices are lower and exporting when prices are higher.

Both apps cover common tasks such as readings, bills, usage and payments. ScottishPower provides the simpler reward; E.ON Next provides the more developed smart-tariff ecosystem.

ScottishPower vs E.ON Next: Pros and Cons

Both suppliers have clear strengths and limitations. The pros and cons below show where ScottishPower and E.ON Next perform well and where each may be less suitable.

Which Supplier Should You Choose?

Choose ScottishPower when renewable fuel mix is your main priority, you can benefit from Half-Price Weekends or you already use its solar and battery products.

Choose E.ON Next when you value stronger customer service, need a competitive tracker, own a compatible EV or qualify for a premium solar export rate.

Is ScottishPower or E.ON Next Cheaper Overall?

There is no permanent price winner. E.ON Next currently offers the stronger tracker and EV deals, while ScottishPower may save more for households that fully use its weekend rewards.

Compare both suppliers using the same:

1. Postcode and annual consumption
2. Meter and payment type
3. Current exit fees
4. Peak and off-peak use
5. EV charging requirements
6. Solar export volume and eligibility

Compare total annual import cost rather than one attractive unit rate. Solar owners should subtract realistic export income, and EV owners should calculate how much charging can genuinely happen off peak.

Final Verdict: ScottishPower or E.ON Next?

E.ON Next is the better overall supplier in 2026. It has the higher Citizens Advice score, a stronger tracker, a cheaper smart EV rate, a longer charging window and the highest premium solar export tariff.

ScottishPower is better for renewable electricity and straightforward weekend rewards. Its published fuel mix is 100% renewable, and Power Saver can benefit households that shift electricity use to weekend afternoons.

Make the final decision using personalised quotations and benefits your household can realistically use.
