Company Profile

Greengauge Building Energy Consultants launched in January 2011. Greengauge are a building services engineering consultancy that aim to provide clients with a comfortable building meeting their expectations by the most efficient means.

Scope of Services

The team take a holistic approach to building design, based on close coordination with the design team and client to ensure that the building meets and exceeds building regulations and provides a highly satisfactory space to live or work. In keeping with the holistic mantra, the team seek to reduce ‘demand-side’ energy use prior to providing impartial advice on renewable energy systems.

We provide full mechanical, electrical and building physics design for small commercial and residential projects, and as mechanical and electrical engineers our recommendations can be developed into full mechanical and electrical designs, for new build and refurbishments. Our services also include energy surveys for businesses and homes providing clients with a strategic plan to optimise their energy use.
