Landlord Insurance Claims Guide 2026 — Claims Process, Loss Adjusters, Betterment, Averaging and FOS Disputes

The claims process — notification, mitigation, documentation and loss adjusters

The first four steps of the claims process are critical to securing a full and prompt settlement:

• Step 1 — Prompt notification: Most landlord insurance policies require the policyholder to notify the insurer 'as soon as reasonably practicable' after discovering the loss or damage — or within a specified number of days (typically 14-30 days for most perils; some policies have shorter notification requirements for specific events). Late notification can give the insurer a ground to reduce or reject the claim — on the basis that the delay has prejudiced the insurer's ability to investigate (e.g., the damage has been repaired before the loss adjuster could inspect; the cause cannot be determined). Best practice: notify the insurer by telephone and confirm in writing (email) on the same day you discover the loss. Keep a record of all notifications and their date and time. For emergency repairs (e.g., emergency boarding up after a break-in; emergency plumber for a burst pipe), carry out essential emergency works to prevent further damage — but photograph all damage beforehand and keep all receipts. Do not carry out any permanent repairs until the loss adjuster has inspected
• Step 2 — Mitigation: The policyholder has a duty to take reasonable steps to minimise the loss after the insured event. Failure to mitigate — allowing avoidable further damage to occur — can give the insurer grounds to reduce the settlement by the amount of the avoidable additional loss. Mitigation does not require the landlord to spend large amounts of money — only reasonable steps proportionate to the nature of the loss. For example: after a burst pipe, turning off the water main to prevent further flooding is clearly required mitigation. Leaving the water running while awaiting the loss adjuster would be a failure to mitigate. For storm damage, covering an exposed roof with tarpaulin to prevent further ingress of water is reasonable mitigation. Emergency mitigation costs (tarpaulins; boarding; emergency plumber call-out) are generally covered by the policy — keep all receipts
• Step 3 — Documentation — the foundation of any successful claim: Thorough documentation before any remediation work is the most important step in a landlord insurance claim. Documentation should include: (a) Photographs — take detailed photographs of all damage from multiple angles before any repair work begins. Photographs should be timestamped (most smartphones do this automatically). Include wide-angle shots showing the overall extent of damage and close-ups showing specific damage points; (b) Video — a video walkthrough of the damaged area is particularly valuable for large-scale damage (e.g., after a flood or fire); (c) Inventory of damaged or destroyed items — for contents claims, list every damaged item with make; model; age; and estimated value. Retain any damaged items (do not dispose of anything before the loss adjuster has inspected — unless they are a health or safety hazard); (d) Contractor estimates — obtain at least 2-3 written estimates from reputable contractors for the repair or replacement work. Do not instruct any permanent repair work before the loss adjuster has visited and agreed the scope of works; (e) Proof of ownership and value — for high-value items, provide receipts; photographs; or professional valuations as evidence of pre-loss value
• Step 4 — Loss adjuster vs loss assessor: For claims above approximately £2,500-£5,000, the insurer will typically appoint a loss adjuster — a professional claims handler who investigates the claim on the insurer's behalf. The loss adjuster: (a) visits the property to inspect the damage; (b) investigates the cause (to confirm whether the damage falls within a covered peril — and to identify any potential exclusion, such as gradual deterioration, wear and tear, or maintenance failure — which would give the insurer grounds to reject); (c) assesses the quantum (the cost to repair or replace the damage at the appropriate standard — see 'betterment' below); (d) produces a report for the insurer recommending acceptance, rejection, or partial acceptance of the claim. The loss adjuster works for the insurer — not the policyholder. For straightforward claims where the cause is clearly covered and the quantum is uncontested, the loss adjuster's involvement is neutral. For complex or high-value claims where the insurer might dispute the cause or apply significant deductions, the policyholder may benefit from appointing a loss assessor. A loss assessor: (a) advocates on the policyholder's behalf; (b) prepares and presents the claim to the insurer; (c) negotiates with the loss adjuster; (d) charges a fee typically of 2-8% of the settlement (payable by the policyholder — not covered by the insurance claim). Loss assessors are most valuable for: fire or flood damage claims over £25,000; claims where the insurer has raised a coverage dispute; and claims where the loss adjuster's quantum is significantly below the policyholder's expectations

Policy exclusions — betterment, averaging, unoccupied property, and disputing a claim

Three exclusions or deductions cause the most common disputes between landlords and their insurers — understanding them before making a claim significantly improves outcomes:

• Betterment deduction: If a repair or replacement results in an improvement over the pre-loss condition of the property, the insurer will typically deduct a 'betterment' amount — the proportion of the repair cost attributable to the improvement. The policyholder is entitled to be indemnified for their loss — restored to the same position as before the loss — but not to be put in a better position. Common betterment scenarios for landlords: (a) storm damage to old single-glazed windows — replacement with modern double-glazed units improves on the pre-loss standard; the insurer deducts the betterment attributable to the improvement in specification; (b) fire damage to a pre-1970s property with old wiring — rewiring to modern standards improves on the pre-loss standard; (c) replacing an old damaged roof covering with a modern equivalent — if the old covering was near end of life, the insurer may argue the replacement provides a disproportionate benefit. Betterment is typically calculated as a percentage of the total repair cost based on the age and condition of the damaged element relative to its expected life. Betterment deductions can be contested — the policyholder should obtain expert evidence on the condition and remaining life of the damaged elements to minimise the betterment deduction
• Averaging clause — the cost of underinsurance: Most buildings insurance policies require the property to be insured for its full reinstatement value — the cost to demolish the existing structure and rebuild it from scratch at current construction costs (including professional fees; planning costs; and temporary accommodation for tenants if required). This is not the same as the market value of the property. For older or larger properties, the reinstatement value can significantly exceed the market value. If the property is insured for less than its full reinstatement value, the averaging clause (also called the 'condition of average') operates: the insurer pays a percentage of any claim equal to the ratio of the insured value to the actual reinstatement value. For example: if a property has a reinstatement value of £500,000 but is insured for £350,000 (70% of the reinstatement value), the insurer will only pay 70% of any valid claim — regardless of the claim amount. A £100,000 flood damage claim would yield only £70,000. Landlords should commission a professional RICS reinstatement valuation survey every 3-5 years — and rebuild cost calculators (such as the BCIS rebuild cost calculator available through the Royal Institution of Chartered Surveyors) provide an estimate between full surveys. Construction costs have increased significantly since 2020; properties insured at pre-2020 rebuild values may be substantially underinsured
• Unoccupied property exclusion and disputing a claim with the FOS: Most standard landlord buildings insurance policies contain an 'unoccupancy clause' that restricts the scope of cover after the property has been continuously unoccupied for a specified period — typically 30, 45, or 60 days (the exact period varies by policy). After the unoccupancy period, some or all of the following perils may be excluded from cover: escape of water (burst pipes; flooding from internal sources); malicious damage (vandalism); theft; storm damage; liability for injuries. The applicable excess may also be increased significantly for claims arising during unoccupancy. Landlords must notify their insurer when a BTL property becomes vacant (e.g., at the start of a void period between tenancies) — failure to notify is a material fact that can void the policy. For extended void periods, specialist unoccupied property insurance should be arranged. For all policy types, if the insurer rejects a claim or offers a settlement the landlord believes is inadequate: (a) Request the insurer's written reasons for rejection or reduction; (b) Review the policy wording carefully; (c) Consider appointing a loss assessor to negotiate; (d) Escalate to the insurer's formal complaints procedure (insurers are required by the FCA to have a complaints process and to acknowledge complaints within 5 business days); (e) If the complaint is not resolved within 8 weeks (or the insurer issues a final response the landlord rejects), refer to the Financial Ombudsman Service (FOS). The FOS is a free service for policyholders — the insurer pays the FOS's case fee. The FOS adjudicates on the basis of what is fair and reasonable in all the circumstances — not purely on strict contractual grounds. FOS decisions are binding on the insurer for awards up to £415,000 (as of 2024), but are not binding on the policyholder (who can still take court action if dissatisfied). The FOS processes approximately 100,000 insurance complaints per year, with property insurance claims accounting for a significant proportion
