How is the Green party's appeal changing?

But it’s not just issues, policies and values that are causing people to consider the Greens. One in six of those contemplating voting for the party (16%) say that it’s a perception they are different and offer a new alternative that draws them most to the Greens, while it’s a belief they represent regular people for 6% and that they appear honest and genuine for 5%.

Just 2% of Green considerers cite the party’s leadership and candidates as their top reason for supporting them.

What are the main reservations those considering voting Green have about the party?

Of course, just because someone is open to voting for a party doesn’t mean they will necessarily do so. Just 16% of those considering voting Green, amounting to 5% of Britons, say they have no reservations at all about voting for the party, though this is up from 9% of those who were considering the party last February.

Belief the Greens are a wasted vote has long dogged the party, and it remains the main doubt about going Green among 36% of those considering doing so. This is, though, down from 50% in February 2025, suggesting their victory in the recent Gorton and Denton by-election (which occurred shortly before fieldwork for this study) has potentially shifted perceptions.

Other common concerns relate to their policies, with 17% highlighting specific policy areas, including 5% who mention the party’s defence policy and 3% each mentioning the party’s drug policies, economic policies and opposition to nuclear power. Another 7% of considerers said more generally that they don’t know or like the Greens’ policies beyond the environment.

Separately, governing experience is another common concern, with 12% of Green considerers saying that the party’s lack of experience is their biggest reservation about voting for them.
