Eon Next Vs Scottish Power

E.ON Next vs Scottish Power often comes down to price for bill-conscious households, with recent examples suggesting E.ON Next can be cheaper on both fixed and variable tariffs. In recent comparison examples, E.ON Next’s cheapest fixed deal has been estimated at a slightly lower annual cost than Scottish Power’s cheapest fix for a typical dual-fuel home on direct debit.

Price is not the whole picture. Exit fees, contract length, service records and features such as solar export payments differ between the two, and the cheapest headline figure only holds if your usage and region match the assumptions behind it. Free Price Compare uses live tariff data so you can check what each supplier actually charges for your postcode before you commit.

If you are stuck on a standard variable tariff above the price cap, moving to a competitive fix from either supplier may cut your annual cost. This comparison sets out where E.ON Next leads, where Scottish Power can still be the right call, and how to switch without paying more than you need to.

Is E.ON Next cheaper than Scottish Power?

E.ON Next can be cheaper than Scottish Power in recent examples, particularly on fixed tariffs. Recent comparison examples put E.ON Next’s cheapest fix slightly below Scottish Power’s cheapest fix for a typical dual-fuel household on direct debit. On variable tariffs, recent examples also show E.ON Next slightly ahead of Scottish Power. These are estimated annual costs for typical usage, so your own figure depends on how much energy you use and where you live.

Both are members of what the industry calls the Big Six, and both price against Ofgem’s energy price cap. Ofgem set the energy price cap at £1,758 a year for a typical dual-fuel household for 1 January to 31 March 2026. E.ON Next’s fixed deals have recently undercut the cap more aggressively than Scottish Power’s offers in recent examples. That said, cheapest is a moving target: tariff prices change month to month, so the only figure that matters is the one quoted for your postcode today.

Is E.ON part of Scottish Power?

E.ON and Scottish Power are separate companies with no shared ownership. E.ON Next is the retail arm of E.ON UK, part of the German-owned E.ON group, while Scottish Power is owned by the Spanish utility Iberdrola. They compete directly for domestic customers and share no billing systems, tariffs or accounts. If you switch between them, your supply transfers through Ofgem’s industry switching process, not through any internal transfer.

This distinction matters when things go wrong. Households who move between two separate suppliers occasionally hit crossed billing, where the old supplier keeps billing after the switch date. Ofgem rules require your old supplier to send a final bill promptly after the switch and to refund any credit balance, so keep your final meter readings and switch confirmation until both accounts close cleanly. Ofgem says suppliers must send a final bill within six weeks of a switch and refund any credit balance within 10 working days of that final bill, under its guaranteed standards.[1]

Scottish Power vs E.ON tariffs compared

Scottish Power and E.ON Next both offer fixed and variable tariffs, but the terms attached to their cheapest deals differ in ways that affect real value. E.ON Next’s headline fixes have tended to be priced lower, but some carry meaningful exit fees, while Scottish Power’s cheapest fixed offers can sometimes have no exit fee. The table below sets out illustrative examples from an August 2026 comparison so you can see the trade-off between price and flexibility.

Figures are indicative and may change.

A longer 24-month fix locks in your unit rates for two years, which suits households who value certainty and expect prices to rise. A shorter fix with no exit fee suits anyone who wants the freedom to move again if a cheaper deal appears.

Should I switch from Scottish Power to E.ON?

Switching from Scottish Power to E.ON Next may save money if you are on Scottish Power’s standard variable tariff and E.ON Next has a cheaper fix available for your postcode. In recent examples, a Scottish Power standard variable tariff has sat above some E.ON Next fixes. If you are already on a competitive Scottish Power fix, the case is weaker, and you would need to check whether any saving beats the exit fee on your current deal.

Before moving, run a quote for your own address rather than relying on a national average, because regional unit rates and standing charges shift the numbers. Ofgem’s switching protections mean the move completes within about five working days, you keep any credit balance, and you get a 14-day cooling-off period once you agree. A concern some households raise is missing a specific advertised tariff version before it is withdrawn; even if a headline deal closes, switching to the next best available fix rarely leaves you worse off than staying on a standard variable rate.

How do exit fees and standing charges affect the real cost?

Exit fees and standing charges can change which supplier is cheaper for you, even when the headline annual figure looks lower. An exit fee is a charge for leaving a fixed tariff before it ends; E.ON Next’s 24-month fixed tariff currently carries a £100 per fuel exit fee on its own tariff page, while exit fees on Scottish Power tariffs should be checked on the live tariff information label before switching. A standing charge is a fixed daily amount you pay regardless of usage, covering the cost of keeping your gas and electricity connected.

Standing charges vary by region and are capped by Ofgem for standard variable tariffs, but fixed deals set their own. Ofgem says that from 1 July to 30 September 2026 the daily standing charge on a standard variable tariff is **57.21 pence for electricity** and **29.09 pence for gas**, and that the standing charge varies by region.[1] For a lower-usage household, a tariff with a slightly higher unit rate but a lower standing charge can work out cheaper overall than a headline deal with a high daily charge. Compare the standing charge and unit rate together, not the annual estimate alone, because that estimate assumes typical usage you may not match.

Which supplier is greener, E.ON Next or Scottish Power?

Scottish Power and E.ON Next both make green electricity claims but take different routes to them. Scottish Power generates renewable electricity through wind farms owned by its parent Iberdrola, while E.ON Next backs its electricity supply with Renewable Energy Guarantees of Origin certificates that match your usage to renewable generation elsewhere on the grid. Both approaches are recognised under UK rules, but self-generation and certificate-backed supply are not identical in environmental terms.

For most bill-conscious households, this is a secondary factor behind price and service, but it matters if reducing your carbon footprint drives your choice. Both suppliers also support the Smart Export Guarantee, which pays households with solar panels for electricity they export to the grid. UK government statistics say direct household emissions from the use of fossil fuels for heating and personal vehicles were **122 MtCO2e in 2023**, which was **25% lower than in 1996**, and electricity, gas and other fuels fell by **42%** over the same period.[1] Export rates differ, so if you have solar, compare the export tariff alongside the import price rather than assuming the cheaper import supplier also pays best for export.

How do E.ON Next and Scottish Power compare on service?

Service records for E.ON Next and Scottish Power differ, and neither consistently tops customer satisfaction rankings among the largest suppliers. E.ON Next generally ranks higher than Scottish Power among the older large suppliers in recent independent scoring, though both trail newer challenger brands on customer satisfaction. Common complaints across both centre on billing accuracy, direct debit reviews and smart meter connection problems, especially for Economy 7 setups. Ofgem’s July to August 2025 Energy Consumer Satisfaction Survey found **82%** of credit meter customers were satisfied with their billing accuracy, and Ofgem’s January 2026 customer service data says this was **80%** in January 2026.[1][2]

Service should sit alongside price when you choose, not above it, because switching for service alone can cost you if the new supplier is dearer. If a large annual saving is on the table, that saving may outweigh a modest service difference for a bill-focused household. To see how E.ON Next stacks up against other large names, our comparisons of British Gas versus E.ON Next and E.ON Next versus OVO Energy add useful context.

Does the energy price cap still matter if I fix?

The energy price cap still matters as a benchmark even when you fix, because it sets the maximum unit rates and standing charges a supplier can charge on a standard variable tariff. Ofgem set the energy price cap at £1,758 a year for a typical dual-fuel household for 1 January to 31 March 2026, and it changes every quarter. The cap limits the rates for a typical user, not a fixed total bill, so your actual cost rises or falls with your usage.

A fixed tariff is only worth taking if it is priced below the current cap once exit fees are factored in and the terms suit your usage. When E.ON Next has advertised its fixes as cheaper than the major suppliers, the comparison has been made against the cap of the day. Because the cap moves quarterly, always check the latest Ofgem figure before deciding whether a fix beats staying on a variable rate. If you are also reviewing your options, our guide to British Gas versus Scottish Power covers how another large supplier prices against the cap.

What support is available if you are struggling to pay?

Support for households struggling with energy bills includes the Warm Home Discount, the Priority Services Register and supplier hardship schemes, all available whether you are with E.ON Next or Scottish Power. The Warm Home Discount is a one-off credit towards your electricity bill for eligible low-income households, applied through your supplier each winter under a government scheme. The Priority Services Register is a free service that gives extra support to people of pension age, those with disabilities and households with young children, including advance notice of planned outages. Ofgem confirms the Priority Services Register is a free service offering extra support to people of pension age, those with disabilities and households with young children, including advance notice of planned power cuts.

Both suppliers must, under Ofgem rules, offer affordable payment plans if you fall behind, and neither can disconnect a domestic customer without following strict rules first. If a switch has left you facing crossed billing between two suppliers, contact both and, if it is not resolved, escalate through the Energy Ombudsman.
