YouGov UK’s bimonthly tracker surveying UK adults’ support for same-sex marriage has released data for 29 June showing that 76% of those surveyed support same-sex couples’ right to marry.

The responses, collected from between 1,627 and 3,416 adults living in the UK, reveal that 51% of responders “strongly support” same-sex marriage, while 25% marked “tend to support”.

In comparison, just 8% answered “tend to oppose” and 7% marked “strongly oppose”, while an additional 8% answered “don’t know”.

Support for same-sex marriage has grown since the survey’s initial release in August 2019, with only 45% of those surveyed selecting that option at the time.

The number of adults who strongly oppose has, in turn, dropped from the reported 10% in 2019.

Same-sex couples have been legally permitted to marry in the UK since 2014, with England and Wales legalising same-sex marriages on 29 March 2014, followed by Scotland on 16 December 2014, and later Northern Ireland on 13 January 2020.

Across the pond, in the US, support for same-sex marriage is dipping, with Republicans turning against the idea.

Gallup poll results from June 2026 found that 65% of those surveyed thought same-sex weddings should be legal. That figure had dropped from 71% in 2022 and 2023.
