Beth Williams . MEng CEng MICE CEPH

Beth joined the Momentum Bath office in 2024 with over a decade of experience in low-energy and low-carbon design. A Chartered Engineer and Certified PassivHaus Designer, she has a particular focus on timber frame PassivHaus buildings and low-carbon retrofit.


Her project portfolio spans from small domestic extensions to sports centres and high-security NHS facilities.


Beth’s passion lies in simplifying the construction of low-energy buildings, making them accessible and affordable for everyone.

Alongside her role at Momentum, she is a visiting tutor at architecture schools in Bath, Sheffield, and UWE, and leads the Bristol & Bath Local Group for the AECB.


Outside of work, Beth is a keen climber and an average paddler, so you’ll often find her on rock or river!
