About Henry Cavendish

Why are we called Cavendish?

Henry Cavendish,  born 1731 educated at Cambridge and a Member of the Royal Society he was the founder and discoverer of the science we know today and as engineers use in our everyday lives.

It is thanks to him that we all enjoy better lives.

It is little known that he discovered the elements of water and the attributes of hydrogen, he established the calculations and physics of what later Newton moved to Gravity. He established the nature of electricity which turned into what we know today as Ohms Law, Coulombs Law and Wheatstone Bridge.

This application and understanding of science's first principles is the ethos we have found is required in engineering the built environment.

In honour of his achievements, we use his name and adopt his ethos in our solutions.


Our reputation is in providing solutions to our clients' problems.

About us

We are first and foremost Engineers and Scientists, able to provide solutions to our clients across a range of sectors in the built environment. From Close Controlled Mission Critical environments through Health Care to Workplace Environments we are able to provide an integrated solution.

Technology led the built environment to become a more complex environment and any service provider needs a mix of knowledge, skills and mindset to adequately support building owners and their agents.

Automation, low energy and reliability are the holy grail and this can only be achieved from experience and knowledge. We have a demonstrable track record to point at in this respect.

Established for 28 years, financially strong, based and focused on London, our experience and knowledge makes us a safe pair of hands for our clients.

Drawing on experience across the sectors to benefit our clients. From Historic Places, Manufacturing and Workplace Buildings we can provide professional engineering services to Study, Engineer and Maintain building services.

How can I employ the best people in the world if I don't provide a world-class environment
