When water damage hits your property—whether from a burst pipe, an escape of water from a neighbouring flat, or a flood event—the professional drying programme that follows is not an optional extra. It is a necessary prerequisite to everything else: the replastering, the redecorating, and the new flooring. And it is almost certainly covered by your home insurance policy.
Most homeowners do not know this. As a result, they either bear the cost themselves unnecessarily, delay starting the drying programme while waiting for an insurer-appointed contractor, or use inadequate domestic equipment when professional industrial units are what the situation requires. This guide explains exactly what your insurance covers, how to claim it correctly, and what happens if you wait too long to act.
The Short Answer
Yes, professional structural drying, including industrial dehumidifier hire, is a standard and expected component of the water damage reinstatement scope under most UK home insurance policies.
It is covered not as a luxury but as a necessity. Insurers know that mould establishes within 24 to 48 hours of moisture remaining elevated in building materials. They know that structural timber above 20% moisture content begins to deteriorate. They know that plasterboard saturated for more than 72 hours starts to lose integrity. A policy that covered the reinstatement costs but not the drying programme that makes reinstatement possible would be both commercially absurd and legally questionable.
Why Dehumidifier Hire is Specifically Covered
Home insurance policies cover the cost of reinstating your property to its pre-loss condition following an insured event. This reinstatement scope includes:
- Professional structural drying: the process of removing moisture from building fabric before plastering, flooring, and decoration can begin;
- Industrial drying equipment: dehumidifiers, air movers, and associated monitoring devices hired for the duration of the programme;
- Delivery, monitoring, and collection of the equipment by a professional restoration company;
- A drying certificate confirming the dry standard has been achieved: the document your insurer requires before authorising any reinstatement works.
Structural drying is not separate from the claim; it is part of it. Loss adjusters appointed by insurers routinely authorise professional drying programmes as a standard element of water damage claims. BDMA-certified restoration contractors submit drying costs to insurers every day, and they are settled as part of the normal claims process.

Your Duty to Mitigate: The Most Important Thing Most Policyholders Do Not Know

Your home insurance policy contains a clause, usually expressed as a condition of cover, requiring you to take reasonable steps to prevent further damage after an insured event occurs. This is called the duty to mitigate.
In practice this means:
- You should not wait for your insurer’s loss adjuster before beginning professional drying
- Loss adjuster visits typically take 3 to 10 days to be arranged after notification.
- Every day without industrial drying equipment allows moisture to penetrate deeper into building materials, mould to establish in the fabric, and the scope of eventual reinstatement to expand
- If avoidable secondary damage occurs because you waited when you could have acted, your insurer may reduce the settlement on the grounds that you failed to mitigate
The practical implication is clear: notify your insurer on the day of the event, get a claim reference number, and instruct professional drying immediately; do not wait for authorisation. Instructing your own BDMA-certified restoration company and beginning drying is not jumping ahead of the process; it is fulfilling your contractual obligation.

What Is Covered and What Is Not
Standard home insurance covers dehumidifier hire when:
- The water damage was caused by an insured peril: a burst pipe, escape of water, storm flooding, or external flooding;
- The equipment is deployed as part of a professional structural drying programme by a reputable restoration company;
- The hire is properly documented (delivery notes, daily moisture monitoring logs, and a final drying certificate).
Standard policies do not cover dehumidifier hire when:
- The moisture is from ongoing condensation or chronic damp unrelated to an insured event (this is a maintenance issue, not an insured peril);
- The property was unoccupied beyond the period permitted in the policy (typically 30 to 60 days)—unoccupied property conditions can affect claim validity;
- The cause of damage is specifically excluded in the policy (some policies exclude flooding from external water sources; check your specific wording);
- There was gradual deterioration or a slow leak that was knowingly left unaddressed (sudden events are insured; ongoing neglect is not).

How to Document Your Claim Correctly

Loss adjusters authorise costs from documentation, not from assertions. The quality of your documentation directly determines how smoothly the drying element of your claim is processed.
From day one, maintain:
- A dated record of when the event was discovered and when professional drying began (this establishes that you acted promptly);
- Photographs at the time of discovery showing the extent of damage before any drying or cleaning started, with timestamps;
- Daily moisture meter readings at defined grid points across all affected surfaces (this confirms the programme is working and when it is complete);
- Equipment delivery documentation: hire agreements, delivery notes, and invoices;
- A drying certificate issued at completion (the specific document your insurer requires before authorising replastering and reinstatement).
Retain every piece of documentation. Submit it as a coherent package with the drying invoice rather than piecemeal. A complete documentation package is what produces a straightforward claim settlement. An invoice with no supporting evidence is what produces queries, delays, and potential disputes.
Using Your Own Contractor vs Insurer-Appointed Contractors
Many insurers have preferred contractors they will appoint to manage water damage claims. You are generally entitled to use your own contractor instead, though you should check your specific policy wording for any approved contractor conditions.
Insurer-appointed contractor:
- No upfront cost to you; the insurer deals with them directly;
- The contractor’s timeline may not reflect the urgency your situation requires
- Response is typically slower than instructing your own contractor directly
Your own BDMA-certified contractor:
- You control the start time, which is critical for meeting the mitigation obligation;
- You choose the equipment specification and programme approach
- You may need to pay upfront and claim back, depending on policy terms
- The contractor is accountable to you rather than to the insurer
For significant water damage, where every day of delay increases secondary damage, instructing your own professional restoration company immediately and notifying the insurer on the same day is almost always the more commercially sensible approach.
What Happens If the Insurer Questions the Drying Costs
Disputes about drying costs occasionally arise, particularly for longer programmes on period or older properties where extended timescales are required. Your protection against such disputes is documentation.
If the insurer argues the programme was longer or more expensive than necessary, your defence is:
- Daily moisture readings showing progress toward the dry standard throughout the programme
- A final drying certificate confirming the dry standard was achieved when the programme ended
- Evidence that the equipment specification was appropriate for the construction type and extent of damage
A professionally documented drying programme produced by a BDMA-certified contractor is very difficult to challenge on grounds of unreasonableness. An invoice from an unknown company with no supporting data is vulnerable to challenge.
If a dispute is not resolved through the insurer’s complaints process, the Financial Ombudsman Service handles insurance disputes free of charge and has found in favour of policyholders in cases where reasonable mitigation costs were disputed.

Conclusion
Industrial dehumidifier hire for professional structural drying after water damage is a standard insured cost under most UK home insurance policies. You have both the right to claim it and the contractual obligation to start it promptly. Document the programme thoroughly, instruct a BDMA-certified contractor rather than relying on insurer-appointed timelines, and submit a complete evidence package with your drying invoice. The cost of professional drying is modest relative to the secondary damage that delayed or inadequate drying produces, and both the equipment and the service are what your insurer expects to pay for.
Frequently Asked Questions
Is industrial dehumidifier hire covered by home insurance?
Yes, professional structural drying including industrial dehumidifier hire is a standard covered cost under most UK home insurance policies following an insured water damage event. It is authorised as part of the reinstatement scope because drying is a necessary prerequisite to plastering, flooring, and redecoration.
Do I need to wait for a loss adjuster before starting professional drying?
No, your policy’s duty to mitigate requires you to take reasonable steps to prevent further damage immediately. Notify your insurer on the same day to get a claim reference number, then begin professional drying. Waiting for a loss adjuster visit that may be 3 to 10 days away while avoidable secondary damage accumulates can give the insurer grounds to reduce your settlement.
What documentation does the insurer need for dehumidifier hire costs?
Your insurer requires hire invoices and delivery documentation, daily moisture monitoring records showing the programme’s progress, and a final drying certificate confirming all surfaces reached the dry standard. This complete package makes it very difficult for the insurer to challenge the reasonableness or duration of the programme.
Can I use my own restoration company rather than one appointed by my insurer?
Generally, yes. Most policies allow you to instruct your own contractor and reclaim costs, subject to any specific approved contractor conditions. Using your own BDMA-certified contractor gives you control over the start time and the contractor’s accountability. Check your policy wording and notify your insurer on the same day you begin work.
