Independent thinking. Lasting impact.
We help organisations solve problems through creative, practical engineering—improving experiences and preserving the environment.
Technical depth.
A wider perspective.
Griffiths Evans provides mechanical, electrical and ICT consulting and design services for new construction and the refurbishment of existing buildings. Based in London, we bring experience across major venues, residential developments, workplaces and public buildings.
Our role is to provide insightful, reliable engineering advice. By looking beyond the immediate boundaries of a discipline, we identify opportunities to add value to the whole project.
We see design as a continuous process: testing ideas, coordinating with the wider team and applying our experience at every stage. Digital modelling and engineering analysis help us turn that thinking into well-resolved, sustainable solutions.
High standards.
Continuous improvement.
Our Quality Management System has been externally audited and certified to ISO 9001:2015. We use clear objectives to manage and assess our performance:
- Work towards zero design defects.
- Continuously improve the way we deliver.
- Design to benefit the environment.
- Ensure client satisfaction.
We invest in our engineers through a structured professional development programme that supports progression towards Chartered Engineer accreditation.
