Early stage design
We support feasibility, structural optioneering and concept development. Structural systems, materials, foundations and buildability are considered alongside architecture, construction sequence, cost and programme.
Wentworth is a specialist engineering consultancy solving complex building and infrastructure challenges.

We bring together engineers, technicians, testing and monitoring experts, and researchers from consultancy and construction backgrounds. We share a passion for sustainability, combining practical experience with research and evidence to use resources carefully and find better ways to design and build.
We support our people through mentoring, shared learning and opportunities to take on new challenges. As part of a global practice, our staff can learn across disciplines, projects and locations, with the encouragement and support to grow personally and professionally.
We are hands-on engineers who care about the craft and the people behind it. We support our colleagues, get to know our clients and stay connected to our friends in construction. That shared understanding helps us solve problems together.
We bring the same care to how resources are used. Through design, research and testing, we explore practical ways to reduce material use and the carbon that comes with it.
We support feasibility, structural optioneering and concept development. Structural systems, materials, foundations and buildability are considered alongside architecture, construction sequence, cost and programme.
We stay involved through design assessments, site support, installation verification and the resolution of technical issues. Our work considers assembly, temporary conditions, access, tolerances and the demands of the programme.
Through Wentworth Labs, we use physical testing, instrumentation and technical validation to investigate capacity, behaviour and performance where analytical assessment needs additional evidence.
Engaging with challenges at consistently high standards.
Clear, effective communication with every stakeholder.
Attention to design detail and functionality.
Working with our clients and one another.
Transparent, ethical operations.
Wentworth began as a site-based engineering team in Wandsworth. Over more than 25 years, the practice has grown into a specialist consultancy working on building and infrastructure projects worldwide.
Our construction experience remains central to the practice: understanding how a design will be built, staying involved as the work progresses and using testing to inform engineering decisions.


Wentworth is part of Keltbray. Our early work alongside its demolition, piling and structures teams shaped the way we approach engineering. Today, we serve developers, architects, consultants, contractors and joint ventures across the industry, maintaining independent engineering judgement.
