About Rubik Builders
Rubik Builders Limited is a Telford-based construction and retrofit contractor specialising in multi-measure decarbonisation, renewables, and retrofit works. Holding PAS 2035 and MCS accreditations, we deliver projects across the Midlands for housing associations, local authorities, and Tier 1 contractors on established frameworks including Fusion21 and Aster Wave 3.

The Role
