Across the UK, expectations around sustainability have shifted from “good practice” to business critical. 89% of UK SMEs now check a supplier’s sustainability credentials before working with them, and sector research from BDO shows construction contracts are increasingly awarded based on lowest carbon emissions rather than lowest cost.
The message is clear: ESG is no longer a nice-to-have but a real revenue driver (or blocker) for businesses.
So what can construction firms do?
According to Sustain IQ, Scope 3 emissions typically account for over 70% of a construction company’s carbon footprint, from materials and transport to subcontractor activity. These are the emissions most tender evaluators now scrutinise.
To stay competitive, firms need to:
Better data equals stronger bids. Without it, you risk losing out on contracts that could have been well within reach.
Whilst carbon is climbing every procurement agenda, public-sector buyers increasingly expect a holistic approach. Under the UK Social Value Model, tenders often include:
Construction can no longer rely on environmental credentials alone. Strong social and governance performance now drives differentiation, especially in tied or high-value tenders.
Even when tenders don’t explicitly request a carbon section, decision-makers are still looking.
Reports show that 89% of small businesses regularly check sustainability credentials of suppliers before deciding to work with them.
They’re looking for things like credible carbon reduction plans (such as those built and tracked through Flotilla’s advanced AI-driven platform), measurable progress against targets and transparent reporting (aligned to the recognised frameworks).
Make it easy for buyers to say yes. Keep your ESG report and credentials visible on your website, link to them in tender responses, and even consider including them in your email signature.
Being report-ready signals maturity, reduces friction in the tender process, and builds immediate trust.
Winning the toughest contracts often means proving more ambitious sustainability performance.
A UK piece on energy efficiency by Food and Drink Manufacturing UK notes that investing in sustainability is vital “to maintain competitiveness and retain hard-won contracts.” as reducing operational emissions and energy use is increasingly tied to contract retention, not just acquisition.
Public-sector buyers have strengthened this further through PPN 006 (previously called PPN 06/21) which requires a compliant carbon reduction plan for major contracts.
To compete at the top of the market, construction firms need to show:
Beyond winning tenders and maintaining compliance, ESG makes real commercial sense. Construction firms see direct benefits such as lower energy and fuel costs, stronger talent attraction and retention and better risk management across supply chains
ESG isn’t the cost centre it’s often seen to be, it’s an investment in long-term competitiveness and reduced business costs.
