Generation Z — UK consumers born roughly 1997–2012 — now make up over 17 million UK residents and are the dominant demographic on TikTok, Instagram, Snapchat and Discord in 2026. Their consumer behaviour differs sharply from Millennials in ways UK marketing literature has only begun to document. The 2024 expansion of social-commerce on TikTok Shop UK, the post-OSA 2023 platform changes, the cost-of-living squeeze on UK 18–28 year-olds, and the BNPL Consumer Credit Act amendment have all reset the UK Gen-Z consumer environment. The 30 dissertation topics below identify research gaps with feasible UK methodology and clear contribution scope for UK undergraduate, Master’s and PhD marketing students.
Why UK Gen-Z marketing dissertations carry unusual freshness in 2026
The UK marketing literature on Gen-Z is dominated by US samples that translate poorly to the UK context. Three UK-specific 2025–26 datasets now make UK-only research possible at scale: ONS Gen-Z labour-market microdata, Ofcom’s Online Nation 2025 reports broken down by age, and TikTok Shop UK seller-anonymised aggregate data shared with selected universities under data-sharing agreements. UK-specific findings now have rare publication potential, and the FCA, ASA and CMA all currently consult on Gen-Z-relevant policy.
