How to Handle a Property Flood or Water Damage
A burst pipe at 11pm can become a £25,000 insurance claim. Here's the first-hour checklist that protects your property, your tenant and your premium.

Introduction
Escape of water is the single most common landlord insurance claim, averaging £8,000 per incident and rising. The first hour determines whether it's a £400 plumber call or a £25,000 reinstatement. Here's the playbook.
First 15 minutes — stop the source
Tenant calls you. Talk them through turning off the stopcock (usually under the kitchen sink, in the airing cupboard or in the bathroom). If they can't find it, the main valve outside at the boundary stops the supply to the property entirely. Time matters — every minute is £20–£50 of damage.
Electrical safety
If water has reached light fittings, sockets or the consumer unit, cut power at the main switch. Do not touch electrics if you're standing in water. Tenants must vacate the room until an electrician confirms safe.
Document before clearing
Photograph or video every room before you move anything — floors, walls, ceiling, furniture, white goods. Insurers will not pay for damage you can't evidence. Time-stamp the photos automatically via phone.
Call your insurer
Most landlord buildings policies include 24-hour escape-of-water response. They'll appoint loss adjusters and contractors, and often pay direct. Calling within 24 hours is usually a policy condition — late notification can void cover.
Emergency plumber
Use a Gas Safe / WaterSafe registered plumber. Get a written quote and itemised invoice. £150–£400 for emergency repair, plus replacement parts.
Drying and dehumidification
Industrial dehumidifiers (£25–£40 per day rental) reduce drying time from 6 weeks to 10–14 days. Hidden moisture under floors and behind walls causes mould within 7 days — insurers expect rapid drying.
Temporary accommodation
If the property is uninhabitable, most buildings policies cover alternative accommodation up to a stated limit (commonly £10,000–£25,000). For uninsured situations, the Homes Act 2018 expects the landlord to bear reasonable hotel cost. Always confirm in writing.
