Start with
what you’ve seen.

You don’t need to diagnose the leak.
Choose the closest match to explore the services. The symptoms alone do not confirm the cause.

Hidden plumbing leaks

A patch of damp can be some distance from the leak. ADI investigates concealed hot and cold water pipes to help establish where the problem starts.

Tell us which room is affected and when the mark first appeared.

Landlord leak detection FAQs

Practical answers about rented properties, survey costs, access and the next steps. Select a question to read the answer.

Which areas does ADI cover for rental property surveys?

ADI’s published service coverage includes England, Scotland and Wales. Give the team the property postcode and suspected leak type to confirm availability. For Northern Ireland, ask ADI to confirm coverage before arranging a visit.

Check survey coverage

How much does landlord leak detection cost?

Ask ADI for a quotation based on the property and investigation required. Confirm the total including VAT, the survey scope and any additional access or repair charges before booking. A general website price cannot establish the cost of your particular job.

Call ADI for a quotation

Will landlord insurance cover trace and access?

Cover depends on the wording of your landlord insurance policy. Ask your insurer whether trace and access is included, what limits or excesses apply and whether approval is required before work begins. A leak detection booking does not guarantee reimbursement.

Using the survey findings

Can ADI attend if the landlord lives elsewhere?

Discuss access with ADI before booking and agree an authorised keyholder. Stay available for questions and confirm who can approve additional work. For a flat, the engineer may also need access to another home or a communal area.

Plan access to a rented property

What should I arrange when a leak affects two flats?

Bring together the observations from both flats and contact the person responsible for shared areas. Ask ADI which parts of the building need access. Water can travel before becoming visible, so the position of a stain does not establish responsibility for the leak.

Coordinate a leak between flats

Will leak detection damage the rental property?

Specialist tests help narrow down the search, but some investigations still require intrusive access to confirm or reach a leak. Tell ADI about floor finishes and access restrictions. Agree any opening-up work and responsibility for making good before it starts.

Can ADI repair the leak during the same visit?

Suitable pipework repairs may be possible, subject to the findings, access, time and an agreed additional charge. A repair is not automatically included in detection. ADI does not carry out roof or structural repairs; drainage work may need separate arrangements.

Will the survey findings help with an insurance enquiry?

Ask ADI what written findings are included and tell the team about information your insurer has requested. A survey record can document the investigation, but the insurer decides whether a claim is covered. Keep the quotation, invoice and relevant correspondence together.

Understand your leak survey report
