Propeller has been ranked 22nd overall in the 2026 B2B Marketing UK Agencies Benchmarking Report. We also placed 8th in the content marketing and thought leadership category, recognising continued investment in helping clients build authority, relevance and commercial momentum through insight-led communications.
The report brings together data from more than 65 leading UK agencies and provides a detailed view of the marketing landscape. This year, it goes further by introducing metrics that matter most to in-house marketers, including client satisfaction, retention, deal size and commercial impact.
Performance beyond visibility
Alongside these rankings, Propeller achieved a +80 Net Promoter Score and a 72% client retention rate over the past year. These results reflect a focus on long-term partnerships and measurable business outcomes.
While overall rankings provide a useful benchmark, the thought leadership category highlights where modern B2B growth is being won. In increasingly competitive markets, visibility is no longer enough. Organisations need to earn trust, shape conversations and create meaningful differentiation.
Building authority that drives growth
At Propeller, this means developing content and platforms that move beyond surface-level engagement. From industry research and reports to executive profiling, events and media strategy, our focus is on helping brands become recognised voices within their categories.
Over the past year, this has included supporting clients to launch new narratives, activate insight at major industry moments and connect reputation with measurable commercial impact. Whether through high-profile industry platforms, owned content or earned media, the goal remains the same: build influence that translates into growth.
A more commercial benchmark for agencies
The inclusion of satisfaction and retention metrics in this year’s report reflects a broader shift in the industry. The conversation is moving from outputs to outcomes and from awareness to value.
This aligns closely with how Propeller partners with clients. The work is designed to support business priorities, whether that is entering new markets,building a new business pipeline, supporting funding rounds or amplifying sector leadership.
Looking ahead
As B2B marketing continues to evolve, the importance of insight, storytelling and cultural relevance will only grow. Organisations that combine strong strong strategy with consistent, credible communication will be best placed to build long-term advantage.
