Construction & Civil Engineering Valuations and M&A in Q2 2026

Construction & Civil Engineering Valuations and M&A in Q2 2026

Selective buyer appetite and widening valuation gaps between business models

The UK construction and civil engineering market entered Q2 2026 with a mixed but constructive backdrop. Residential and some parts of commercial building remain under pressure, yet infrastructure-linked activity, repair and maintenance, and technically differentiated services tied to energy, water, transport and digital infrastructure are proving more resilient. That distinction matters for valuation and M&A.

Why valuation dispersion is widening

The most important message from the trading comparables is not simply which bucket screens highest. It is that public markets are assigning very different valuations to different construction-related business models. The chart below summarises average EV/2026E EBITDA multiples for each category:

Public market valuations show that the highest ratings sit with power and utility infrastructure specialists, reflecting strong growth and scarce capability. Engineering and technical consulting, residential and diversified construction groups trade in a similar mid-single-digit band, while core infrastructure and civil engineering contractors, although strategically important, remain lower-rated due to contract risk, working capital demands and capital intensity.

Infrastructure remains attractive because investors want exposure to water, power, transport, environmental services and data-centre-related delivery. But not all infrastructure-linked businesses are equal in valuation terms. The premium tends to sit with specialist, technical or asset-light models, while core contracting businesses remain strategically valuable but lower-rated. Public markets are cautious on civils contractors, but strategic buyers and sponsors are still prepared to pay up selectively for the right infrastructure assets.

UK market backdrop: mixed output, better strategic positioning

Constructionline's Q1 2026 report showed published project value rising from about £11 billion in Q1 2025 to nearly £15 billion in Q1 2026, with both the number and value of awards also higher year-on-year:

At the same time, the operating environment remains uneven, private housing and parts of commercial new-build remain subdued, even as infrastructure, repair and maintenance, and publicly supported work hold up better:

What recent UK deal activity is saying

Recent UK transactions continue to support this selective thesis. VINCI's acquisition of FM Conway highlights strategic demand for infrastructure services businesses with strong positions in highways, surfacing, public realm and local authority work.

The same applies to Aureos, the former Keltbray Infrastructure Services business. Its repositioning around power, rail, renewables and highways reflects the continued relevance of energy security, decarbonisation and regulated infrastructure as investment themes. Likewise, NG Bailey's acquisition of Engineering Solutions Group in March 2026 shows how strategic buyers are broadening capability in infrastructure-adjacent niches such as water and specialist engineering services.

Taken together, these deals suggest that UK M&A appetite is strongest where three factors come together:

Implications for owners

For owner-managed businesses, this is a market that rewards preparation and positioning. Sellers with exposure to frameworks, regulated customers, long-duration programmes, specialist technical delivery or defensible regional positions are likely to be viewed more favourably than businesses with patchier pipelines, thinner margins or heavy dependence on a handful of customers or projects.

That does not mean general contractors cannot transact well. It means they need to work harder to demonstrate quality of earnings, risk management, margin discipline and transferable customer relationships. In a selective market, clarity of equity story often matters as much as current trading.

The strategic value of infrastructure-linked businesses is high, but headline listed multiples still vary meaningfully by business model. Sellers should therefore avoid simplistic benchmark comparisons and focus instead on where their business sits on the spectrum between specialist, recurring and technically differentiated earnings on one side, and more operationally intensive contracting risk on the other.

For owners considering succession or a partial exit in the next 12–36 months, this is an opportune moment to benchmark where your business sits on that spectrum and understand how buyers are likely to value it.
