Top green energy suppliers compared

About Top green energy suppliers compared

Green energy suppliers are ranked here on the numbers that decide a household bill: what a unit of power costs, what the standing charge adds whatever you use, and what you are tied into once the first term ends. This is a shortlist from the 54 brands in the wider green energy supplier list, set out in rank order with every figure carrying its own ref so the value matches its source. The trade-off runs straight through the table. Suppliers strong on rate and standing charge often ask for longer commitments or expect a smart meter to be in place, while the shorter, more flexible deals tend to carry a higher standing charge or fewer ways to reach support. Renewal deserves as much attention as entry, which is why fixed terms and exit fees sit beside the plan types for every member, from fixed and variable through dynamic, green, time of use and electric vehicle tariffs. Fuel coverage is set out too, since Elli sells electricity only, and renewable claims are compared on what sits behind them, whether certificates, a power purchase agreement or their own generation.

How we picked

Every supplier here is scored on three weighted pillars. Cost carries 40% of the total, the offer carries 40%, and trust carries 20%. Cost looks at what you pay for a unit of power and what the standing charge adds to the connection. The offer pillar weighs what a plan includes, such as the range of tariff types, fuel coverage, contract length and the exit fee. Trust looks at how a supplier backs its renewable claim and how customers can reach it. Figures are taken from each supplier's own published terms, tariff and support pages alongside independent market comparison data, and each one keeps its own ref so the value shown always matches the source it came from. Where a supplier publishes several figures for one field, such as a unit rate range or a list of fixed terms, the whole range or list is shown rather than one flattering value. A field with no published figure is simply left out, and an absent figure is never read as a strength or a weakness. Partners are listed first, then everyone else in score order, so any sponsored position is visible before the reasoning starts.

Our top picks

1. 1. Octopus Energy

   Octopus Energy follows Powerpeers in this ranking on flexibility: the exit fee is €0, fixed terms run 12, and tariff types of fixed, variable and green cover the fixed, variable and green options on electricity and gas. The supply is 100% renewable and rests on certificates, with the company trading as Octopus Energy Italia Srl for customers in IT. Support reaches you on email, phone and chat. The trade-off is cost, since a unit rate of €0.17 and a standing charge of €6 sit above the cheapest figures in this ranking. Vattenfall, next in order, adds 12,000,000 customers and a reference annual cost of €953.30.

   • Fixed terms: 12
   • Exit fee: €0
   • Unit rate: €0.168

   Pros

   • Exit fee is €0, so a fixed term can be left early without a penalty
   • Green tariff is backed by 100% renewable supply on a certificates basis
   • Tariff choice covers fixed, variable and green on both electricity and gas
   • Support runs on email, phone and chat
   • Standing charge of €6 is near the low end of the compared field

   Cons

   • Fixed terms run 12 months and then need a renewal decision, since no separate renewal price is set out
   • Unit rate of €0.17 sits mid-field, so it does not undercut every rival on usage
   • Tariff list covers fixed, variable and green only, with no time of use or electric vehicle option as listed

2. 2. Budget Thuis Internet

   Budget Thuis Internet holds a solid mid table place in this ranking on the strength of scale and a clean tariff set. It supplies electricity and gas at 100% renewable, backed by certificates, with tariff types of fixed, variable and dynamic and fixed terms of 12 and 36. It trades as Budget Thuis B.V. and serves 1,000,000 customers in NL. What it holds back is breadth of contact and tariff flavour, since support runs on chat, phone and help centre only with no email among them, and no green tariff appears in the types listed. Green Planet Energy eG, ranked next, backs its claim with own generation and adds electric vehicle and time of use plans.

   • Top download speed (Mbps): 1,000
   • Upload speed (Mbps): 1,000
   • Price from: €3.75

   Pros

   • Download and upload match at 1,000 mbps and 1,000 mbps, so sending a large file is as quick as downloading one.
   • The setup fee is €0, so nothing has to be budgeted to get connected.
   • Contract terms run 12 and 24 months, so you can take the shorter commitment rather than the longest one.
   • A discount for multiple lines is available, which suits a household running more than one phone line.
   • Mobile sits on the KPN network with 5G, so broadband and a phone line can come from one provider.

   Cons

   • Broadband terms run 12 and 24 months and a rolling monthly option is not among the terms listed, so moving home early still means a commitment.
   • Coverage sits in a single market, NL, so anyone living outside the Netherlands should set this provider aside.
   • Support runs on chat, phone and help centre only, with no email channel listed for questions that need a written trail.
   • Mobile roaming runs on fair use terms across 43 countries, so frequent travellers should expect limits on use abroad.

3. ON8. om nieuwe energie: best for om nieuwe energie

   om nieuwe energie is a provider of local, sustainable electricity generated by local solar and wind energy projects.

   • Markets: NL

   Pros

   • Supplies sustainable electricity linked to nearby solar and wind generation projects
   • Focuses on local generation, giving supply a clear regional connection
   • Connects household supply with solar and wind projects rooted in surrounding areas

4. E9. EVM: best for EVM

   Regional energy supplier offering 100 percent green electricity, natural gas, heat electricity, heating, solar systems and e-mobility, with advice in 11 customer centres.

   • Markets: DE

   Pros

   • Offers solar systems, heat pumps, heating and e-mobility from one regional source
   • Provides face to face advice across 11 customer centres
   • Supports home energy control linking solar, heat pump and wallbox use

   Cons

   • Operates as a regional supplier rather than a nationwide option
   • Range centres on home energy, with less for other property types

5. 10. Powerpeers: best for Top pick

   Powerpeers sets the pace in this ranking on the two figures that drive a household bill: unit rates of €0.11 to €0.30 and a standing charge of €0.21 to €0.39, both at the lower end of the suppliers listed here. Electricity and gas both come as 100% renewable, tariff types cover dynamic, fixed and variable, and support runs on email, chat and phone. The thing to weigh before you commit is length, since fixed terms of 12, 24 and 36 tie you in for longer stretches than most rivals in this table. Octopus Energy, ranked next, keeps terms down to 12 and charges €0 to leave, but lists a higher standing charge of €6.

   • Fixed terms: 12, 24, 36
   • Unit rate: €0.11 to €0.30
   • Standing charge: €0.214 to €0.394

   Pros

   • Electricity and gas sit in the same range, since electricity and gas covers both fuels and a household on both can stay with a single supplier.
   • Commitment length is a choice rather than a fixed default, with terms of 12, 24 and 36 available.
   • The fixed contract is backed by 100% renewable electricity, which suits shoppers who want a green tariff alongside a set price.
   • Support runs on email, chat and phone, so customers can pick the channel that suits them rather than settle for a single route.

   Cons

   • Unit rates run €0.11 to €0.30, and the upper end sits well above the lower end, so an accurate budget matters.
   • Tariff types stop at dynamic, fixed and variable, leaving out the time-of-use and prepay choices electricity-ratings lists in fixed, ev and time of use.
   • On unit rate the ranking is 4 of 23 brands, so the strong standing charge position does not carry over to consumption.

What to look for

Unit rate

The core of every bill. The median unit rate across this ranking is €0.27, the lowest listed is €0.11 and the highest is €6.29. Match the rate to the way your household actually uses power before anything else.

Standing charge

A flat cost that lands on the bill whatever you use. The median here is €15, the lowest listed is €0.09 and the highest is €144. On a small annual usage this can outweigh a cheaper unit rate.

Exit fee and term length

€0 of the plans listed here carry no exit fee, and 80% run longer than a single year against 60% for a single year. Look at both together, since a low rate on a long commitment is only good if you stay.

What backs the renewable claim

Certificates cover 71.4% of suppliers in this category, while power purchase agreements and own generation take smaller shares. If where the power comes from matters to you, ask what sits behind the label.

Ways to get help

A help centre is offered by 88.5% and a phone line by 80.8%. Both matter once a meter reading is wrong or a switch is delayed, and several suppliers here list only one of them.

Meter requirements

58.6% of the suppliers listed say a smart meter is required. Check what you already have in place before you pick a plan, because an upgrade adds lead time to a switch.
