Leaking Loft Tank Emergency Guide

Stay Calm. Protect Your Home.

A leaking loft tank can quickly cause water damage to ceilings, insulation and belongings if it is not dealt with promptly.

This guide explains how to make the situation safe, reduce water damage and know when to call a qualified plumber.

Step-by-Step Guide

Step 1 – Turn Off the Water Supply

If it is safe to do so, turn off the water supply feeding the loft tank. If you are unsure, turn off your property's main stop valve.

Step 2 – Contain the Water

Place towels, buckets or FloodFort flood bags where water is collecting to help prevent it spreading further.

Protect stored belongings and nearby areas where possible.

Step 3 – Check for Obvious Leaks

Look for water leaking from the tank, overflow pipe or connecting pipework.

Do not climb into the loft if the floor feels unsafe or there is extensive water damage.

Step 4 – Reduce Further Damage

If it is safe to do so, move belongings away from the leak and dry standing water as quickly as possible.

If water is leaking through the ceiling below, keep people away from the affected area.

Step 5 – Contact a Qualified Plumber

Arrange for a qualified plumber to inspect and repair the leaking loft tank before restoring the water supply.

FloodFort Tip

Keep your FloodFort Kit somewhere easy to access so you can respond quickly to unexpected water emergencies.

Using FloodFort flood bags early can help minimise water damage while you wait for repairs.

Need More Help?

If the leak is severe or you cannot safely access the loft, contact an emergency plumber immediately.

If water has reached electrical wiring or light fittings, switch off the electricity at the consumer unit if it is safe to do so.
