Our verdict on each
100Green
100Green suits GB households that want renewable electricity and a free exit fee, with fixed terms set at 12 months and no charge to leave before the term ends. The offer covers both fuels, and the renewable supply sits behind a power purchase agreement.
Reset
Reset suits Italian households who want a fixed, green tariff with nothing to pay to leave, and it is comfortable on support as well. The trade-off is price per unit, which sits mid-table at 21 of 23, while the exit fee of €0 ranks 1 of 29.

Pros and cons
100Green
Pros
- Renewable electricity at 100%, with the supply behind it coming from a power purchase agreement.
- Own generation is rewarded: exports are paid at £0.12.
- Both fuels come from one supplier, with electricity and gas covered on the same account.
Cons
- A smart meter is required for the electric vehicle tariff, so meter status decides who can take that plan.
- Fixed terms run for 12 months only, so no longer fixed term is listed for anyone wanting a rate locked for years.
- Supply covers GB only, so a household outside that market has to look elsewhere.
Reset
Pros
- Exit fee of €0 ranks 1 of 29 brands, so leaving early costs nothing
- Fixed terms run 60 months, which is long enough to plan a switch around
- Both fuels, electricity and gas, sit on the same fixed and green range, so a dual fuel switch stays simple
Cons
- Unit rate of €0.45 ranks 21 of 23, so the per unit price is not the cheapest on the table
- Tariff types cover fixed and green, and there is no variable, time of use or electric vehicle option as Powerpeers and Endesa list
- Supply runs in IT only, so households outside Italy cannot buy it
Who each suits
100Green
Who it suits
- Households in GB that want renewable electricity and gas from one supplier.
- EV drivers who already have a smart meter or are ready to have one fitted.
- Anyone who may move mid-term and wants a free exit fee.
Who should look elsewhere
- Powerpeers, for a dynamic tariff: 100Green's list is fixed, variable and green, while Powerpeers runs dynamic, fixed and variable.
- Vattenfall, for a household that wants only fixed, green and variable choices, since Vattenfall lists fixed, green and variable without the vehicle and time-of-use options.
Reset
Who it suits
- Households in Italy who plan to stay put for the length of a fixed term
- Anyone who wants a green tariff without paying to leave early
- Dual fuel households who want electricity and gas under one supplier
Who should look elsewhere
- Households wanting a time of use or electric vehicle tariff, where Endesa and Electricity Ratings offer more
- Anyone outside Italy, since supply runs in IT only
- Buyers shopping mainly on the lowest unit rate, where Powerpeers lists a wider tariff range

Questions about each
100Green
What does 100Green supply?+
100Green covers both fuels, with electricity and gas available from the same supplier, so a household using both does not need two providers. Renewable supply applies to the electricity side, and gas is bundled into the same account for homes that want one relationship.
Is the electricity genuinely renewable?+
Electricity is listed as 100% renewable, and the basis for that claim is a power purchase agreement. The green offer is tied to contracted renewable generation, which is the part buyers of green tariffs tend to ask about before they switch.
Reset
Does Reset charge a fee for leaving early?+
No. The exit fee is €0, and Reset ranks 1 of 29 brands on that measure. That makes it a practical option for households who expect to move home or renegotiate during the fixed term of 60 months.
How long is the fixed term and what happens at the end?+
Fixed terms run 60 months. The term is fixed throughout, and the unit rate of €0.45 sits inside that block rather than resetting partway through, so the price you sign up for is the price you keep paying until the term ends.
