UK pension giants Nest and Railpen are collaborating on a £1 billion fund aimed at fueling British science and tech startups. Named the Scale-Up Fund, this initiative targets companies past the initial concept phase that require substantial capital to commercialize their innovations and expand operations.

Backing British Innovation

The Scale-Up Fund builds on commitments made in the Mansion House Accord of May 2025, where 17 pension providers pledged to increase investments in UK-based ventures and infrastructure, totaling a staggering £50 billion directed toward venture capital and infrastructure projects.

Supported by the British Business Bank, the fund seeks to prevent promising UK startups from being swallowed by Silicon Valley investors. It represents a clear strategy to deploy domestic pension capital into local tech firms, competing with global players who have often been the default growth-stage backers.

With Nest already committing to invest up to £1 billion in venture capital by 2030, this fund is seen as a primary vehicle to deliver on that goal. The government's push in late 2025 to steer pension savings toward future "sci-tech unicorns" added momentum to this effort.

Challenges in the UK Tech Investment Scene

Traditionally, UK pension funds have lagged behind peers in the US, Canada, and Australia with deploying venture capital domestically. This has allowed startups to receive early-stage backing at home but then shift headquarters overseas for growth-stage financing, resulting in economic value migrating away from the UK.

The Scale-Up Fund aims to counteract this trend by aggregating capital from multiple pension providers and leveraging the British Business Bank’s analytical capacity, enabling the fund to write growth-stage investment checks of significant size.

This development follows a broader context where UK institutions are seeking new ways to support domestic innovation. It echoes government-backed initiatives worldwide trying to lock capital within national technology ecosystems.
