The Best-Value 100% Renewable Energy Tariffs for 2024
Cheap clean energy, that’s what we like!
Everyone wants to save money on their energy bills, especially when the energy price cap is expected to in October 2024.
Lots of people also want to do their bit for the climate by buying clean renewable energy.
But is renewable energy just too expensive for normal households during a cost-of-living crisis?
Not necessarily, no.
The bad news is that the cost of energy in the UK has soared in recent years and is now unaffordable for many families. In 2024, the average monthly bill for gas and electricity for a 3-bedroom home with average usage is around £130 per month .
The good news is there are at least two 100% renewable tariffs at this price point. So you don’t need to pay over the odds for green energy.
In this post, I break down four of the best-value energy tariffs which are 100% renewable. For a fair comparison, we’ll be considering a 3-bedroom house with average energy consumption, paying for both electricity and gas with a monthly direct debit.
Let’s dive in.
Top 4 Best-Value Green Energy Tariffs
Octopus Energy: Fixed Octopus
I’ve been a customer of for years and they’re the best energy supplier I’ve had so far.
They source 100% renewable electricity for all their tariffs and are one of the biggest investors in solar power in the UK. They offer optional carbon-offset gas and they have special deals for combining your energy with solar panels or electric cars. Their customer service and customer communications are excellent — fast, clear and friendly. (Nice branding, too!).
Octopus has competitive prices. For a 3-bedroom house with average energy usage, they quote £130 per month direct debit for duel fuel — electricity and gas, with their Fixed Octopus tariff. Their Flexible Octopus tariff is currently comparable in price, but it can go up and down with the energy market.
(For transparency, I’m paying a lot more than that with their Flexible Octopus tariff, so this has prompted me to finally do that meter reading I’ve been putting off for months and shoot them an email about why my bill is so high!).
SO Energy: So Flex
I’ll be honest, I didn’t know about until researching this article.
They’re an up-and-coming challenger energy company sourcing 100% renewable energy for their fixed tariffs. I can’t speak to their customer service, but they have good reviews . They let customers vote on which renewable energy source to invest in, which is a nice touch I haven’t seen before. Gotta love democratising energy!
SO Energy is competitive on cost, they actually came up on Go Compare for the cheapest energy tariffs of any kind, not just renewable ones.
I got a quote for £138 per month for dual fuel for an average-sized home — but keep in mind this can go up and down with wholesale energy costs. Their fixed So Poppy tariff is £151 per month if you prefer certainty.
OVO Energy: 1 Year Fixed + Greener Electricity
OVO Energy’s Greener Electricity fixed tariff is sourced from 100% renewable energy.
The cost is a little more than the above options, I was quoted £140 per month direct debit for dual fuel for an average home. Note there is also a £75 exit fee for both fuels!
Keep in mind that OVO Energy is not a fully renewable company — their other standard tariffs aren’t 100% renewable. Their total fuel mix (the average across all tariffs) is about half renewables and half fossil gas. So if you choose the Greener Electricity tariff, even though the company is sourcing enough renewables to cover your consumption, the company is still investing in fossil fuels as well.
Given this and the fact it’s not even the cheapest on this list, I wouldn’t choose this option personally.
Good Energy: Good Energy Standard
For an energy company that is fully renewable and ethical, consider Good Energy.
I haven’t used them myself, but I’ve heard good things about their service from friends and they have . 100% of their electricity comes from renewables. Their gas is 10% biogas and includes carbon offsets for the rest. They also offer a full range of zero-carbon home upgrades, like solar panels, heat pumps, EV charging and more.
Their Good Energy Standard tariff is slightly higher at £150 per month for an average-sized home, which is variable. This means it can go up and down with national energy prices. They don’t seem to be offering a fixed tariff at the time of writing.
FYI, Good Energy (along with 100Green and Ecotricity) are .
Honourable Mentions
There are two other fully renewable energy companies that are worth a look: and green energy veteran . These are very ethical but more expensive than others on this list.
100Green quotes £164 per month for their standard fixed tariff for an average-sized home, and Ecotricity comes in at an estimated £170 per month (unclear whether that’s fixed or variable). Both these options offer green gas, with 100Green claiming to be the only supplier to source 100% biogas which is quite impressive.
There are other companies that offer a renewable energy tariff but get most of their energy from fossil fuels, like OVO Energy but with dirtier fuel mixes. There’s also EDF which is mainly nuclear based — the marmite of energy sources — which is zero-carbon but not renewable, and has other environmental problems.
Final thoughts
If you’re not already using a 100% renewable energy tariff, I recommend switching. And if you are, it’s worth checking you’re getting the best deal.
22% of the UK’s carbon emissions come from powering our homes, , so you’ll have a big impact on the mission to net zero. And remember, energy bills are expected to go up again later this year.
Yes, I know it’s a bit of a hassle to switch suppliers, but it’s easier than you think and it’s well worth it for cheaper bills and clean zero-carbon energy.
