Where the Work Is: Infrastructure, Retrofit, and Regional Construction in 2025

Despite cost pressures, policy shifts, and planning challenges, the UK construction industry in 2025 is holding its ground, just not evenly. Some sectors are seeing consistent investment, while others have slowed. For developers, contractors, and white-collar professionals across the project lifecycle, it’s never been more important to understand where the activity is concentrated and why.

At Warwick Callow, we’re in constant conversation with employers and candidates. Here’s what we’re seeing across infrastructure, retrofit, and regional delivery right now.

Infrastructure Remains the Most Stable Workstream

Even in a year defined by caution and cutbacks, infrastructure is proving resilient. The reasons are straightforward: long-term public funding cycles, multi-year frameworks, and strategic national priorities.

Projects tied to highways, water, energy and logistics continue to progress. For example, National Highways is pressing ahead with its RIS2 and RIS3 commitments, and water companies are launching major works under AMP8. In power and renewables, enabling civils, grid upgrades and battery storage facilities are also driving demand in specialist areas.

The cancellation of parts of HS2 has been widely reported, but that hasn’t dried up activity. Enabling works around Birmingham, regional rail upgrades, and new transport interchange schemes are still creating opportunities. Contractors working in these spaces are actively hiring project managers, planners, and commercial leads, especially those with NEC experience and exposure to public-sector oversight.

The work may not always make headlines, but infrastructure is where consistency lives in 2025.

Retrofit Is Quietly Becoming a Mainstream Pipeline

Retrofit used to sit at the edge of the market. That’s no longer true.

Public funding streams such as the Social Housing Decarbonisation Fund (SHDF), Local Authority Delivery (LAD) and the Public Sector Decarbonisation Scheme (PSDS) are creating a reliable base of demand. These aren’t one-off contracts; they are multi-year delivery programmes.

Most of the work is focused on making existing buildings more energy-efficient: insulation upgrades, low-carbon heating, PV panels, and improved ventilation. It’s technically complex and often delivered in live environments. Schools, housing estates and healthcare facilities can’t shut down for refurbishment, which makes planning and stakeholder coordination critical.

The result is steady demand for professionals who can sequence works, manage compliance, and keep stakeholders informed. Assistant site managers and trainee planners are getting hands-on experience in retrofit early in their careers, and in many cases, developing skills faster than peers in traditional new-build roles.

It’s also proving attractive for commercial professionals. Retrofit contracts often carry complex KPIs, layered funding conditions and tight margins, making experienced QSs and commercial managers highly valuable.

Regional Breakdown: Where Activity Is Strongest

Across the UK, the picture varies. But some patterns are emerging.

• London and South East: Major infrastructure remains active, particularly in highways, rail and utilities. Office refurbishments and university estate upgrades are picking up, especially where retrofit funding is involved. Planning and safety professionals are in steady demand.
• Cambridge and Oxford Arc: This region remains a hotspot for science parks, laboratory facilities and life sciences R&D hubs. These schemes demand specialist knowledge and high compliance standards, which is driving demand for senior planners, technical PMs and quality-focused site leads.
• West Midlands: While HS2 north of Birmingham has been paused, the Midlands still benefits from existing infrastructure momentum. There is movement on enabling works, highway upgrades, and local authority retrofit frameworks, often in partnership with regional Tier 2 contractors.
• North West: Ports, water infrastructure and decarbonisation retrofits are creating pockets of strong activity. Contractors are targeting experienced professionals with regional knowledge and flexibility.
• Wales and South West: Activity is more localised but supported by green energy projects, solar installations, and smaller-scale civils. In places like Cornwall and Swansea, retrofit funding is driving school and care facility upgrades.

One notable trend: contractors are redeploying staff across regions to chase active frameworks. That mobility is opening gaps and opportunities for professionals who are ready to step in locally.

What Professionals Should Know

If you’re a white-collar professional, knowing where the work is helps you focus. Not just on where to apply, but on what skills and project types to build around.

Professionals with infrastructure or retrofit experience are especially sought after, particularly those with a track record in compliance-heavy, multi-stakeholder environments. Employers are also favouring candidates who can manage documentation, liaise with local authorities, or track works against complex funding criteria.

There is also increased demand for people with digital coordination experience. Those comfortable with cloud-based programme tools, site dashboards, or documentation systems linked to Building Safety Act requirements are well positioned.

For early-career professionals, exposure to frameworks and retrofit programmes is already proving valuable. Site-based roles on these schemes offer structured experience, varied challenges, and greater visibility of stakeholder expectations. All of this is becoming a differentiator in a slower hiring climate.

What Employers Are Doing

Many contractors and developers are reshaping their hiring plans based on regional funding allocations and retrofit pipelines. Larger contractors are building out delivery teams with experienced QSs and assistant PMs who can flex between new build, refurbishment and compliance-led retrofit. Smaller firms are targeting professionals with regional ties and experience working directly with housing associations or local councils.

Across the board, time-to-hire is shortening where frameworks are active. Once funding is confirmed, delivery teams need to be assembled quickly. That is shifting the market back toward proactive hiring and pipeline conversations, rather than reactive CV screening.

At Warwick Callow, we are actively supporting clients and candidates who want to understand where consistent work is likely to come from, not just this quarter, but over the next year. Whether you are building a delivery team for a decarbonisation framework or exploring a move into infrastructure, we are here to help you align the right people with the right projects.
