Start with the building’s use
Describe what the affected areas are used for, when they are occupied and the reason for the enquiry. A layout change, an existing system concern and a new installation each need a different scope.
The Health and Safety Executive, the workplace safety regulator, describes ventilation as supplying fresh air to indoor spaces in its workplace ventilation guidance (hse.gov.uk). In your message, distinguish a fresh-air requirement from a temperature-control concern or a process-specific extraction requirement.
Keep specialist requirements visible
If the work involves a commercial kitchen, a production process or another specialist area, name that use explicitly. General building ventilation and a specialist extraction project should have their requirements described separately.
Include any existing specification or assessment you hold and say which decisions remain open. Describe the documents rather than copying sensitive operational information into the form.
Work around your premises
Project planning needs to account for:
- The London site postcode and access arrangements.
- The rooms or equipment included in the work.
- Occupied areas and available work windows.
- Known restrictions on disruption.
- Refurbishment, handover or other project dependencies.
For maintenance within a wider project, identify the equipment that needs attention and any recorded faults. For new work, explain what is already designed or selected.
