About us

Wooster Jeffs Associates is a building services and engineering consultancy practice based in St Albans.

The practice was formed in 1997 by the integration of two practices, Peter Jeffs Associates (which was formed in 1976) and Wooster Associates (which was formed in 1992), both of which were already located in St Albans.

Taking over an established building design company is both an exciting opportunity and a great responsibility. In 2025, Wooster Jeffs Associates became part of a bigger building services’ group.

While bringing fresh ideas and innovation, we are committed to preserving the company’s rich history and core values that have shaped its success. The legacy, craftsmanship, and reputation built over the years will remain at the heart of its identity, ensuring a seamless blend of tradition and progress. Our goal is to honour its past while continuing to guide it toward a dynamic and thriving future.

As a trusted leader in mechanical and electrical design, we deliver forward-thinking solutions across a wide range of sectors, including public and private healthcare, education, residential care, commercial offices, industrial facilities, and large-scale developments.

Our expertise covers the full scope of mechanical, electrical, and public health design, from precision fault analysis and system optimisation to full project design and management.

We conduct in-depth surveys and reports, implement strategic cost control, and provide comprehensive briefing materials to support clients in assembling expert design teams.

With a commitment to innovation, efficiency, and reliability, we engineer smarter, more sustainable environments built to perform today and into the future.
