Who they are, and who they act for
A loss adjuster is appointed by the insurer to investigate the claim and recommend how it should be settled. They are usually independent of the insurer as a business, and often genuinely fair, but they are not your representative. A loss assessor is the other thing: someone you hire, who acts for you, usually for a percentage.
On smaller escape of water claims there may be no adjuster at all, just a handler on the phone and a contractor sent to survey. On anything involving a lifted floor, a ceiling down, or a dispute between flats, expect an adjuster.
The questions, in the order they usually come
When did you first notice something wrong?
This is the important one and it is asked early, casually, while the adjuster is still taking their coat off. It is the gradual damage test. The Financial Ombudsman's guidance to insurers on gradual damage says they should consider whether the customer "couldn't reasonably have been aware of the damage happening gradually" and whether they "made the insurance claim, or took reasonable action, as soon as they could reasonably have known about the problem".
Answer with a date if you have one and with "I do not know" if you do not. Do not say "oh, it has probably been going on a while" to sound reasonable. That sentence has ended claims.
What did you do when you noticed?
They are checking that you mitigated: turned the water off, moved what could be moved, got someone out. Anything you did counts, including the bucket and the towels, and photographs of it count more.
Who have you had out, and what did they find?
Where the detection report does its work. An adjuster who is handed a dated report with pressure test figures, moisture readings against a dry reference and thermal images with the scale showing has most of their site visit done for them. An adjuster handed an invoice has to reconstruct it themselves, and everything they cannot verify becomes a question.
Where exactly is the leak, and how do you know?
Not a room. A point. Read what an insurer-ready report contains for the form that answer needs to take.
Why did that much floor have to come up?
The trace and access question. Every square metre opened has to be justified by the method that pointed at it. This is the single strongest argument for non-invasive detection first: a report showing that thermal imaging and tracer gas narrowed the search before anything was cut is a report where the access cost defends itself.
When was the system last serviced or checked?
Maintenance. The NRLA's guidance on escape of water claims makes the point plainly for landlords, that "proactive maintenance is not only good practice, but it also strengthens your position should a claim arise". If you have boiler service records, a landlord gas safety record, or a receipt from the last plumber, have them out.
Is the property occupied, and was it occupied when this happened?
Unoccupancy clauses are real and many policies restrict cover after a period of vacancy. Answer accurately.
What is damaged, and what do you want done about it?
Room by room. Distinguish buildings from contents as you go: plaster, screed, flooring, kitchen units and decoration sit on the buildings policy, while furniture and appliances sit on contents.
