Practical preparation guidance, not a diagnosis or legal advice. Arrange authorised access and follow ADI’s instructions for your particular survey. Do not undertake intrusive work or work at height on the basis of this guide.
Describe the layout clearly
Give ADI the affected flat number, floor and room. Explain what is above it, if known, and where the building’s shared pipework can be accessed. A simple labelled sketch can make the arrangement easier to understand than a chain of forwarded messages.
Establish who can arrange access
Identify a contact for each flat or shared area that may need inspection. Ask the building manager about entry arrangements and available plans. ADI identifies restricted access in blocks of flats and shared supplies as a potential obstacle to finding a leak, so discuss gaps before the appointment.
Keep a single account of events
Collect dated photographs and note when occupants see water. Record which room each photograph shows. Keep personal details out of messages to people who do not need them, and send each occupant the appointment information relevant to their home.
Pass on the survey findings
Choose one person to collect questions after the visit. Share relevant findings with the people arranging further access or repair work, and retain the survey’s description of any areas that could not be inspected.
