What the investigation needs to establish
Several properties on one supply can make isolation and interpretation more complicated. The instruction needs a clear system boundary, agreed access and an authorised contact for affected occupants. A coordinated testing plan can then address the right section.
Bring the useful details
Provide a plan if available, identify isolation controls and name the person who can authorise shared access.
Keep the boundaries clear
Wider shared-system work is scoped and quoted separately.
A method with a purpose
Pressure testing may form part of the investigation when the conditions suit it. We explain what the result supports and what remains uncertain.
Agree a specific quotation
Commercial and wider shared-system work is quoted separately. Identify the systems, properties and access involved so the instruction can be defined.
