Cavendish Maintenance

"As one of the leading energy efficient Maintenance companies in London, Cavendish Engineers Ltd pride ourselves on the service we provide to our clients. One of the biggest factors in providing a quality service comes down to the Subcontractors we use.

The Essential Group have been part of our wider team for some years now. They provide us with a unrivalled service for our CCTV and Security Systems in some of our most prestigious buildings in London. Along with providing quality maintenance, they've also lead some of our most challenging system upgrades including full IP Cameras in our Heritage and Listed buildings and the full installation of a new Emergency Security system. We've also used the Essential Group of additional specialist labour!

The engineers always attend emergencies promptly, are well presented and able to resolve the issues with no problems at all.

We love working with the Essential Group and I know that no job is too big or small for them. They always make me feel like I'm top of the list when I call. If you work in Facilities Management, you know how hard it is to find reliable contractors and that's why we'll be keeping our grip on The Essential Group for years to come. Without them, our job would be a lot harder!"
