MKM EcoVadis Gold in the UK: sustainability and product shifts for specifiers
Reviewed by Tom Sullivan

First reported on The Construction Index
30 Second Briefing
EcoVadis has awarded MKM Building Supplies a Gold medal, placing the independent merchant in the top 5% of 150,000 companies assessed worldwide for environmental, ethical, labour and human rights, and sustainable procurement performance. Key measures include opening its first two BREEAM Excellent certified branches in Cheltenham and Wolverhampton, rolling out electric forklift trucks across the network, and tightening supplier requirements via a strengthened Code of Conduct. For specifiers and contractors, MKM is also widening access to renewable heating technologies, energy‑efficient products and lower‑carbon construction solutions aligned with evolving UK building regulations.
Technical Brief
- EcoVadis benchmarked MKM against 150,000 organisations worldwide, placing it in the top 5% performers.
- Local branches are mandated to design and run their own ESG initiatives, within a group-wide framework.
- Company-wide projects explicitly target both environmental impact reduction and operational performance improvement, not just compliance.
- EcoVadis’ methodology required MKM to evidence policies, actions and outcomes, not just publish high-level commitments.
- Strengthened supplier Code of Conduct embeds sustainable procurement and ethical supply chain criteria into merchant–supplier relationships.
- Go Home Safe programme underpins ongoing investment in health, safety and workforce wellbeing across MKM’s branch network.
- ESG head Rachel Constable positions the Gold rating as validation of long-term, business-wide behavioural change, not a single-year push.
Our Take
EcoVadis appears several times in our Environmental coverage, and the contrast between MKM Building Supplies’ Gold-level top‑5% placement and Doka’s Silver top‑15% rating signals that UK construction‑supply chains are starting to stratify visibly on audited ESG performance.
With MKM Building Supplies simultaneously expanding its UK branch network (per the separate BMF board adviser piece), a high EcoVadis score likely strengthens its position in public‑sector and tier‑one contractor tenders where third‑party sustainability ratings are now routinely weighted.
