EON Next Solar Panels Review: Costs, Packages & Alternatives
EON Next (formerly E.ON) is one of the UK’s largest energy suppliers and now offers solar panel and battery storage packages for homeowners. Their solar offering is marketed as an all-in-one service — from survey to installation and aftercare — bundled with smart tariff benefits for existing EON Next customers.
A typical EON Next solar panel system costs £5,500–£9,000 fully installed in 2026, depending on system size and whether a battery is included. But is buying solar panels from your energy supplier the best option, or are you better off comparing quotes from independent MCS-certified installers?
Quick Answer
EON Next solar panels are a convenient option if you want a single point of contact for your solar installation. Prices range from £5,500–£9,000 for typical 3–5 kW systems, which is competitive but not always the cheapest. Independent MCS installers often offer the same equipment for 10–20% less. EON Next's main advantage is smart tariff integration and the convenience of dealing with your existing energy supplier. Always compare at least 3 quotes before committing.

What is EON Next Solar?
EON Next is the retail energy brand of E.ON UK, one of the “Big Six” energy suppliers. E.ON rebranded its UK retail operations to EON Next in 2022, combining its energy supply business with solar panel installations, battery storage, heat pumps, and EV chargers under one roof. EON Next solar panels are not manufactured by EON — they source equipment from established manufacturers (typically Longi, JA Solar, or similar tier-one brands) and use a network of subcontracted installers to carry out the work.
“Energy suppliers entering the solar market can offer convenient bundled packages, but homeowners should always compare prices with independent MCS-certified installers. The equipment is often identical — the difference is in pricing, aftercare, and flexibility.”
The company
EON Next is the UK retail arm of E.ON SE, a major German energy company. E.ON serves approximately 5 million UK customers. The solar and home energy division operates alongside their electricity and gas supply business.
What they offer
Solar panel systems (typically 3–5 kW), battery storage add-ons, smart export tariffs, home surveys, installation by MCS-certified subcontractors, and ongoing monitoring via the EON Next app.
How it works
You request a quote online, EON Next arranges a home survey (remote or in-person), you receive a system design and price, and their subcontracted installers carry out the work. The process typically takes 6–10 weeks from enquiry to installation.

How much do EON Next solar panels cost?
EON Next solar panel pricing is broadly in line with the wider UK market, though not always the cheapest option. Prices vary depending on system size, roof complexity, location, and whether a battery is included. All prices below include VAT (0% VAT applies to residential solar PV installations until March 2027).
| System Size | EON Next (est.) | Independent Installers (est.) | Difference |
|---|---|---|---|
| 3 kW (8–10 panels) | £5,500–£6,500 | £4,500–£5,500 | EON typically 10–20% more |
| 4 kW (10–12 panels) | £6,500–£7,500 | £5,500–£6,500 | EON typically 10–15% more |
| 5 kW (12–14 panels) | £7,500–£9,000 | £6,000–£7,500 | EON typically 15–20% more |
| 4 kW + 5 kWh battery | £8,500–£10,500 | £7,500–£9,000 | EON typically 10–15% more |
Why are EON Next prices higher?
Large energy suppliers like EON Next carry higher overheads — national marketing, call centres, and management layers — which are reflected in pricing. They also use subcontracted installers, adding a margin on top of the installation cost. Independent local installers have lower overheads and often quote directly. The equipment used is typically identical (same tier-one panels, same inverter brands). Always compare at least 3 quotes before making a decision.
EON Next finance options
EON Next offers finance on solar installations, including interest-free credit on selected packages (subject to status and availability). Typical terms range from 12 to 120 months. Always check the total cost of credit — interest-bearing finance can add £1,000–£3,000 to the overall cost. If you can pay outright or use a 0% solar finance deal, you will get the best value.
EON Next smart tariffs & solar export
One of EON Next’s key selling points is integration with their energy tariffs. If you are an EON Next energy customer with solar panels, you can access their solar export tariff and potentially benefit from time-of-use pricing.
EON Next Solar Export
EON Next offers a Smart Export Guarantee (SEG) tariff that pays you for surplus electricity exported to the grid. Rates vary but are typically 4–6p/kWh in 2026. This is broadly in line with other suppliers, though specialist tariffs from Octopus Energy may offer higher rates (up to 15p/kWh with Agile Export).
Battery optimisation
If you have a battery, EON Next’s app can help schedule charging and discharging to maximise savings. However, EON Next’s smart tariff options are currently less advanced than Octopus Energy’s Agile, Flux, or Intelligent Go tariffs, which offer more granular time-of-use pricing and better battery arbitrage opportunities.
How EON Next export rates compare
| Supplier | Export Rate | Notes |
|---|---|---|
| EON Next | 4–6p/kWh | Fixed SEG rate |
| Octopus Energy (Fixed) | 4–7.5p/kWh | Fixed SEG rate |
| Octopus Agile Export | Variable (avg 8–15p/kWh) | Half-hourly variable rate; best with battery |
| Octopus Flux | Up to 24p/kWh (peak) | Requires compatible battery; time-of-export pricing |
| British Gas | 3–5p/kWh | Fixed SEG rate |

EON Next vs independent solar installers
The most important comparison for anyone considering EON Next solar panels is against independent, local MCS-certified installers. Here is how they stack up in 2026.
| Factor | EON Next | Independent Installers |
|---|---|---|
| Pricing | 10–20% higher on average | More competitive; lower overheads |
| Equipment | Tier-one brands (limited choice) | Wider choice of brands and models |
| Installation quality | Subcontracted; varies by region | Direct; often same team every time |
| Aftercare | Call centre support; can be slow | Direct contact with installer; often faster |
| Finance | 0% credit available on some packages | Some offer finance; varies by company |
| Smart tariffs | Integrated with EON Next export tariff | You choose any SEG provider (Octopus, etc.) |
| Flexibility | Standardised packages | Fully bespoke system design |
| Company stability | Large multinational; very low risk | Varies; check reviews and trading history |
“There is nothing wrong with buying solar panels from a large energy supplier, but you should always get comparison quotes. The panels and inverters are often the same brands used by independent installers, so the question is whether the convenience and brand trust justify the price premium.”
Our recommendation
EON Next is a reasonable choice if you value convenience and the reassurance of a large brand. However, we recommend getting at least 2–3 quotes from independent MCS-certified installers before committing. You may find the same equipment installed for £500–£1,500 less. The equipment, MCS certification, and manufacturer warranties are identical regardless of who installs the system.
What to check before buying from EON Next
If you are considering EON Next solar panels, here are the key questions to ask and factors to check before signing a contract.
Questions to ask EON Next

Red flags to watch for
- Pressure to sign on the day — always take time to compare
- Vague equipment specs (“tier-one panels” without naming the brand)
- Finance terms that are unclear or have hidden fees
- Unrealistic savings projections (“eliminate your electricity bill”)
- No clear information on who handles warranty claims
- Inability to provide references or Trustpilot/Google reviews
EON Next Solar Panels FAQ
Are EON Next solar panels any good?
EON Next uses tier-one solar panels from reputable manufacturers like Longi and JA Solar, which are the same brands used by independent installers. The panels themselves are good quality. The main consideration is pricing — EON Next is typically 10–20% more expensive than independent MCS installers for equivalent systems. Installation quality depends on the subcontractor in your area.
How much do EON Next solar panels cost?
EON Next solar panel systems typically cost £5,500–£9,000 for a standard 3–5 kW system without a battery in 2026. With a battery, expect £8,000–£11,000. These prices are broadly in line with the market but tend to be at the higher end. Always compare with at least 2–3 independent quotes.
Do I need to be an EON Next customer to buy their solar panels?
No. You do not need to be an existing EON Next energy customer to purchase their solar panel packages. However, some smart tariff benefits and export tariff integration work best if you are also an EON Next electricity customer.
What warranty do EON Next solar panels come with?
EON Next solar installations typically come with a workmanship warranty of 5–10 years covering the installation itself. The solar panels carry the manufacturer's product and performance warranty (usually 25 years). Inverters are typically warranted for 10–12 years by the manufacturer. Battery warranties vary by brand (usually 10 years).
Can I get a battery with EON Next solar panels?
Yes. EON Next offers solar panel + battery packages, as well as battery-only retrofits for homes that already have solar panels. Battery options typically range from 5–10 kWh. Popular battery brands used include Huawei Luna, GivEnergy, and Fox ESS, depending on availability.
How does EON Next compare to Octopus Energy solar?
Both EON Next and Octopus Energy offer solar panel packages. Octopus Energy's main advantage is its superior smart tariffs (Agile, Flux, Intelligent Go) which can save significantly more when paired with a battery. EON Next offers a more traditional, package-based approach. For either, compare their quote against independent MCS installers.
Is it better to buy solar panels from EON Next or an independent installer?
Independent MCS-certified installers typically offer the same equipment for 10–20% less than EON Next. They also tend to offer more bespoke system designs and direct aftercare. EON Next's advantages are brand trust, potential finance options, and convenience. We recommend getting quotes from both and comparing the total cost for equivalent equipment.
How long does EON Next solar installation take?
The process from initial enquiry to completed installation typically takes 6–10 weeks with EON Next. The installation itself usually takes 1–2 days for a standard system. Lead times can be longer during peak demand periods (spring and summer).
Do EON Next solar panels qualify for the Smart Export Guarantee?
Yes. All EON Next solar installations are MCS-certified, which is a requirement for the Smart Export Guarantee (SEG). You can choose any licensed electricity supplier for your SEG payments — you are not obliged to export to EON Next.
Can I switch energy supplier after installing EON Next solar panels?
Yes. Your solar panels and any warranties remain unaffected if you switch energy supplier. The panels and inverter carry manufacturer warranties that are independent of your energy supplier. You may lose specific EON Next tariff benefits, but you can sign up to SEG export with any licensed supplier.
