Burst Pipes – Practical Guidance For Insurers
Operational Guide For Insurers, Loss Adjusters & Restoration Professionals
Interim Guidance – January 2026
EXECUTIVE SUMMARY
Purpose Of This Guide
This guide supports insurers and loss adjusters in making timely, proportionate and defensible decisions when managing burst pipe losses, particularly during surge conditions.
Burst pipe events often present greater operational complexity than external flooding due to vertical and horizontal water migration, widespread saturation of structure and contents, and disruption to power and heating systems. If early decisions are not sequenced correctly, these claims can escalate quickly in cost, duration and complaint risk.
Scope & Limitations
- This guidance is advisory in nature
- It does not constitute a regulation or mandatory standard
- It creates no new legal or contractual obligations
- Each case should continue to be assessed on its individual merits
Intended Audience
This guide is intended for:
Insurers
Loss Adjusters
Surveyors
Restoration Professionals (managing burst pipe losses)
It is not intended for householders.
When This Guidance Applies
Use this guidance where:
- A burst pipe has caused internal water damage
- Structural elements and contents are saturated
- There is potential for ceiling collapse, power disruption or extended drying
- Claims volumes are elevated (e.g. winter freeze events)
Why This Matters For Insurers
Burst pipe losses typically involve vertical and horizontal water migration, increasing the risk of secondary damage, avoidable BER (Beyond Economic Restoration) and extended claim duration if not sequenced correctly.
Stage 1: Immediate Safety & Stabilisation
Decision focus: risk control and programme integrity
Electrical Supply & Heating
- Internal wiring and sockets are likely to be wet
- Temporary electrical boards are typically required
- Minimum 4 double sockets for a standard domestic property
- Once electricity and heating are isolated:
- The property will cool
- Mould does not develop in cold conditions
Common pitfall: Reintroducing heat before sufficient drying capacity is available accelerates uncontrolled evaporation, increasing mould risk and programme duration.
“Cold buildings don’t grow mould — problems start when heat is reintroduced without enough power or drying control.” Stephen Sinacola, National Flood School
Insurer guidance: If practicable, leave the property cold until the drying strategy and power requirements are confirmed.
Stage 2: Asbestos Containing Material (ACM) Decision Gate
Decision focus: safety, compliance and downstream cost
Where ceilings or wall linings are affected:
- ACM sampling should be undertaken as early as possible
- Ideally within 24 hours
If sampling is completed promptly:
- Wet plasterboard can often be removed within 48 hours
- Remaining wet significantly reduces dust and fibre spread
Do not install drying equipment before ACM results are known.
“Early ACM testing protects people, programmes and costs — delaying this decision nearly always creates downstream issues.” Chris Netherton, CEO
Settlement Implications
- Positive ACM result: Contents removal must follow ACM procedures; the property must be declared clean before drying commences.
- Negative ACM result: Controlled drying of contents in situ may proceed, preserving restoration options.
Stage 3: Contents Management & BER Control
Decision focus: avoidable BER (Beyond Economic Restoration), storage costs and complaint risk
Early contents decisions have a disproportionate impact on claim outcomes.
Key Guidance
- Do not remove contents while wet to accelerate strip-out
- Wet removal into storage creates ideal mould conditions
- Previously restorable items may become BER
Insurer-led Approach
- Dry contents in situ for 5–7 days where practicable
- Enable early restoration vs replacement assessment
- Agree BER settlements promptly
- Avoid unnecessary storage, secondary handling and associated cost
“Removing wet contents to storage is one of the fastest ways to turn a restorable claim into a total loss.” Julia Stockdale, Head of Contents
Additional operational note: Extended power outages may cause fridges and freezers to defrost. Early removal of food items can prevent secondary odour damage and avoid unnecessary appliance replacement.
Stage 4: Standing Water & Floor Coverings
Decision focus: drying efficiency and secondary damage prevention
Where ACM results permit:
- Wet carpets, underlay and rugs should be extracted promptly
- This removes the majority of standing water and accelerates drying
Best Practice
- Cut BER floor coverings into manageable sections
- Bag in heavy-duty plastic to prevent secondary damage
- Remove gripper rods, particularly at thresholds (injury risk)
Photographic records and representative samples should be retained to support validation and settlement.
Stage 5: Heat, Humidity & Drying Strategy
Effective drying depends on:
- Adequate heat retention
- Sufficient electrical capacity
- Controlled air movement
- Appropriate dehumidifier selection
Control Parameters
- Target temperature: >16°C where practicable
- Avoid exceeding 25°C
- Maintain humidity below 68% RH to prevent mould growth
Unnecessary ceiling removal increases heat loss and can materially extend drying times.
“Drying is about control, not just capacity — heat, airflow and humidity must work together.” Stephen Sinacola, National Flood School
Technical Reference: Air Exchange & Dehumidification Performance
For technical reference where drying performance optimisation is required.
Air Changes Per Hour (ACH)
Correct ACH ensures moisture-laden air is efficiently removed and replaced, supporting effective and defensible drying programmes.
Condensing Dehumidifiers
- Most effective at 18–30°C, RH >40%
- Recommended 6–8 ACH minimum
Desiccant Dehumidifiers
- Effective below 10°C
- Suitable for dense materials and complex losses
- Recommended ~4 ACH
Calculation
Machine airflow (m³/hr) ÷ Area being dried (m³) = ACH
Multiple machines may be required to achieve target rates.
Collapsed Or Compromised Top-floor Ceilings
Decision focus: thermal retention and drying efficiency
Where a ceiling is damaged but intact:
- Leave the ceiling in situ if safe
- Remove wet insulation from above
This approach improves heat retention, drying performance and programme control.
“Retaining the thermal envelope is often the difference between an efficient drying programme and a prolonged one.” Nick Lea, Technical Director
Major Loss, Commercial & At-risk Occupiers
Decision focus: BI (Business Interruption) exposure and welfare considerations
Specialist heat-drying solutions may be appropriate for:
- Large domestic properties
- Commercial losses
- Limited electrical capacity
- Vulnerable or disabled occupiers
Disaster Care maintains heat-drying trailer capacity to support accelerated drying where BI exposure or welfare considerations are significant. Cases should be assessed individually.
GUIDANCE Summary
Top 5 Decision Points In Burst Pipe Losses
Sequence Before Speed
Early actions determine restoration options, drying duration and claim cost. Acting quickly without control often removes options later.
Do Not Dry Before The ACM Decision
Drying equipment must not be installed until ACM results are known. This is a critical safety and compliance gate.
Cold Properties Do Not Create Mould
Mould risk increases when heat is reintroduced without sufficient power and drying control.
Contents Decisions Drive Cost
Removing wet contents too early can convert restorable items into BER, increasing storage, handling and settlement cost.
Control Heat, Air & Humidity Together
Drying effectiveness depends on achieving appropriate temperature, airflow and humidity simultaneously — not on equipment volume alone.
Why This Matters For Insurers & Adjusters
These decision points directly influence:
- Programme duration
- Avoidable BER
- Storage and handling costs
- Business interruption exposure
- Complaint and dispute risk
- Defensible settlement outcomes
Priority Principles For Insurers & Adjusters
Before works commence:
- Safety and sequencing are critical decision drivers
- Speed without control increases claim cost and programme risk
- Drying equipment must not be installed until early decision gates are passed
- Irreversible actions can limit restoration options and reduce settlement flexibility
“Trying to accelerate a job too early often increases cost and removes options later.” Paul Sharkey, Network Manager
