Top 30 M&E contractors set for growth – ranking

The country’s leading M&E contractors saw revenue rise by nearly a fifth last year driven mainly by cost inflation.

But major firms are predicting a stronger year ahead as data centre work, commercial retrofits, life sciences and lab work starts to fire-up the sector.

The industry’s biggest players are also taking on major contract roles on data centre work as £100m-plus M&E packages hit the market.

During last year, Dalkia leap-frogged NG Bailey to become the industry’s biggest player after a rebrand that consolidated the Imtech, Inviron and SPIE UK brands.

Wates-owned SES, Skanska’s SRW and Gratte Brothers enjoyed strong sales growth lifting the firms up the rankings to now sit just below the big three.
