TikTok Reels Growth Redefines User Habits
TikTok’s explosion in the UK isn’t slowing down. With nearly 35 million monthly users nationwide, TikTok has integrated itself into daily routines. In response, Instagram pushed Reels harder, and YouTube expanded Shorts aggressively.
What’s striking in 2025 is how these formats are no longer just “extras” on platforms—they are the platforms. Meta reports that Reels now account for over 65% of watch time on Instagram in the UK, while TikTok continues to outpace every other app in average session duration.
Even traditionally text- or image-heavy platforms are pivoting to short-form. Facebook now auto-recommends Reels to passive users, and LinkedIn has even tested micro-video intros for personal branding. The short-form takeover is systemic.

Why Reels & Shorts Outperform Traditional Content
There are several reasons short-form video dominates UK social media in 2025. First is the delivery: bite-sized clips feed into our fast-paced lifestyles. They’re easy to consume and perfect for multi-tasking users. Secondly, algorithms love them. These videos generate higher retention and more engagement, leading to greater organic reach.
Another factor is content accessibility. A user doesn’t need a high-end setup or editing expertise to go viral with Shorts or Reels. The democratization of content creation has made the playing field broader, and the results speak for themselves.
Creators and Brands: Adapt or Fade
Content creators who doubled down on short-form video over the past 18 months are now reaping the benefits. From makeup tutorials to comedy sketches, British creators have leaned into authenticity and consistency. Brands have followed suit. In fact, over 78% of UK businesses with active social profiles now incorporate Reels or Shorts into their marketing.
E-commerce integration is also more seamless. Platforms like TikTok Shop and Instagram Shopping now support direct purchases through videos, turning scrolls into sales. This fusion of entertainment and commerce is setting a new benchmark for ROI.
What’s Next for UK Short‑Form Video?
The trend isn’t cooling off—it’s accelerating. In July 2025, platforms are testing AI-assisted content generation, enhanced personalization, and even monetized reactions. Expect to see more cross-platform integrations, where content created on one platform is automatically optimized for others.
Short‑form video is no longer a trend; it’s the infrastructure of UK digital communication. To ignore it is to opt out of relevance.
