The UK is in the middle of the largest infrastructure investment programme it has seen in a generation. The government has committed at least £725bn to infrastructure development over the coming decade, with major programmes accelerating across energy, transportation, and water.[1] For founders building Greentech solutions, delivering that pipeline sustainably represents one of the most significant commercial opportunities in the market today.
At Murphy Capital, Greentech is one of our three core Infratech investment verticals. We invest in Greentech not as a sustainability obligation, but because we see it as one of the highest-growth, most commercially dynamic areas of the entire Infratech market. Founders building here are not simply responding to regulation. They are reshaping how infrastructure is designed, delivered, and sustained.
Sustainability as a commercial priority
The urgency of the challenge is not in doubt. While the UK economy as a whole reduced greenhouse gas emissions by 41% between 1993 and 2023, construction’s scope 1 emissions rose by over a third in the same period.[2] From November 2026, a mandatory 10% biodiversity net gain requirement will also apply to all Nationally Significant Infrastructure Projects in England, adding further regulatory weight to an already accelerating market.[3]
The most forward-thinking infrastructure organisations are no longer treating sustainability as a burden to be managed. They are recognising it as a source of measurable operational and commercial impact. The technologies capable of reducing emissions are frequently the same technologies capable of cutting costs, reducing waste, and improving long-term asset performance. The commercial case for Greentech adoption is not a secondary benefit of the sustainability agenda. In many cases, it is the primary one.
The technology landscape
Greentech for infrastructure spans a wide and rapidly evolving range of categories, from advanced green materials and circular construction technologies to carbon tools, alternative fuels, and intelligent energy systems. Innovation across these categories continues to expand, but adoption remains constrained by capacity, trust, and fragmented markets.
The investment opportunity this creates is substantial. According to Beauhurst Insights, Cleantech, a closely related industry that includes companies developing technology to reduce harmful environmental impacts, was among the sectors where average deal sizes in 2025 outperformed the three-year average, even as overall transaction volumes fell.[4]
The challenge of getting to market
For many Greentech businesses, the hardest part of scaling is arguably not building the technology, but rather gaining access to the infrastructure environments where that technology can be deployed, validated, and scaled. Procurement cycles can be long. Live project access can be difficult to secure, and generating the operational performance data that major clients require may take years to accumulate independently.
Murphy Capital partners with founders to help them address this challenge. Backed by Murphy’s £8.2bn order book across energy, transportation, and water, Murphy Capital offers Greentech founders direct access to live infrastructure projects, active procurement relationships, and the operational depth of a business with 75 years of delivery experience.
Critically, Murphy Capital does not only invest in these businesses; we buy from them. Acting as both investor and customer, Murphy Capital enables founders to move from innovation to commercial deployment faster, providing real contracts, real revenue, and the credible operational data that opens doors across the infrastructure supply chain.

The opportunity ahead
The real commercial opportunity is being created right now, in the procurement decisions and technology choices being made across every major infrastructure programme in the country.
The founders who move early, prove their technologies in real-world environments, and build credibility within the infrastructure supply chain will define what the next generation of sustainable infrastructure delivery looks like. Murphy Capital is focused on finding and backing them.
