Safely Back to Business

Safe and compliant


Before your employees return to your offices you need to consider likely health and safety implications. Depending on how the building was shutdown there’s potential for issues and steps you will need to plan now to ensure your premises are ready for reoccupation and fulfil your legal obligations as an employer.

Darenth Valley can help you to ensure every requirement on the list below that’s relevant to your building and how it was shutdown, is covered by an appropriately trained specialist, so that you can offer a safe and healthy environment to your returning employees. We have been working throughout the shutdown, carrying out planned and reactive maintenance, reactivation work and deep cleaning and sanitising, to keep buildings safe and legal, healthy and happy for our clients.

Chilled/cooling closed water systems

Inspect and test electricity and water supplies to ensure they are working. Circulation and pressure testing and cleaning, flushing and testing for microbiological activity and Legionella control to be carried out where relevant.

Air conditioning

Ensure no refrigerant leaks have developed in direct expansion  (DX) air conditioning units and that the system is able to provide cooling to the designed levels of requirement.

Electrical systems

Arrange a visual inspection of electrical systems by a qualified specialist, together with testing of the insulation resistance of all power and lighting circuits, generators, motors and switch gear.
