The UK construction industry is set to experience a 1.6% growth in 2025, primarily fueled by substantial investments in data centers and renewable energy projects. This growth is further supported by government initiatives, including the AI action plan and increased infrastructure spending. However, challenges such as high interest rates and subdued private sector demand may temper the expansion.
Data Center Investments Propel Growth
In recent years, the UK has witnessed a surge in data center investments, significantly contributing to the construction sector’s growth. For instance, Equinix announced a £3.9 billion investment to build a major new data center campus in Hertfordshire, UK. This facility, encompassing over two million square feet and offering 250 MW of processing capacity, is expected to generate 2,500 construction jobs and over 200 permanent skilled roles once operational. The development is projected to contribute significantly to the UK economy, with KPMG estimating £120 million in wages and up to £3 billion in annual Gross Value Added (GVA) during construction, followed by £260 million annually once operational.

Similarly, Basildon Council approved a £1.3 billion data center project in Wickford, Essex, developed by Caineal. This center is expected to generate over 600 construction jobs and 120 skilled operational roles, with construction beginning after planning formalities conclude. The project is part of a broader effort to boost Essex’s digital infrastructure and establish Basildon as a hub in the UK’s AI revolution. (itpro.com)
Government Initiatives and Infrastructure Spending
Government initiatives have played a pivotal role in supporting the construction industry’s growth. The AI action plan, launched in January 2025, aims to develop data center projects worth £13.2 billion ($17 billion). Additionally, the government has announced increased investments in infrastructure, energy, healthcare, and residential housing, further bolstering the construction sector. (businesswire.com)
In March 2025, the government allocated £10 billion ($12.9 billion) towards road infrastructure improvements for the years 2025 and 2026, including £4.8 billion ($6.2 billion) to the strategic road network for maintenance, £1.6 billion ($2.1 billion) for local road maintenance, and £1.3 billion ($1.7 billion) for road renewals.

Challenges and Market Outlook
Despite the positive outlook, the construction industry faces challenges. High interest rates and subdued private sector demand remain headwinds, potentially impacting growth. However, the short and medium-term outlook remains positive, with growth expected to accelerate in 2026-27, underpinned by policy support in the form of planning reform, increased housing and energy infrastructure commitments, and ongoing public investment in schools and hospitals.
