Burst Pipe in the Flat Above? What to Do in the First Hour

Water coming through your ceiling can be alarming, especially when the source is in another flat. Acting quickly can help limit damage, but your safety comes first. You don’t need to diagnose the fault or attempt a repair: focus on keeping people safe, alerting the right people and recording what’s happening.

Use these steps as a practical guide for the first hour. If there is immediate danger, such as a ceiling at risk of collapse or water reaching electrical fittings, move away and call emergency services if needed.

First 10 minutes: Keep clear and alert your neighbour

1. Move people and pets away from the affected area. Keep clear of water dripping near lights, sockets, appliances or other electrical equipment. Don’t touch anything wet or try to catch water directly beneath a light fitting.

2. Contact the resident in the flat above. Knock, call or use your building’s usual contact method. Explain where the water is appearing and ask them to check for a leak.

3. Ask them to stop using the suspected water source. If they can identify the source and reach their stopcock safely, they may be able to turn off the water supply to their flat. They should contact an emergency plumber if the leak continues or they can’t locate the cause.

4. If you can’t reach them, contact your managing agent, landlord or building emergency contact straight away. Don’t force entry into another flat.

Water can travel through floors and ceilings, so the place where it appears may not be directly below the fault. The source could be a failed appliance, a plumbing connection or a leak from pipework. Don’t assume you know where it started.

If water is near electrics, treat it as a safety issue

Water and electricity are a dangerous combination. Keep away from wet sockets, switches, light fittings and appliances. Don’t touch a ceiling light that is dripping, and don’t use an appliance that has been affected by water.

If you can reach your flat’s consumer unit without going near the water, and can operate it from a dry, safe position, switch off the electricity to the affected area, or the main switch if necessary. If you’re unsure, don’t take the risk. Leave the area and get urgent professional advice.

Do not switch the electricity back on until a qualified electrician has confirmed it is safe. If there is an immediate risk of fire, electric shock or collapse, get everyone out of the affected area and call 999.

Next: Limit damage without putting yourself at risk

Once the immediate danger has been assessed, take simple steps to limit damage:

• Put a bucket or bowl beneath a drip only if it’s safe to do so.

• Move furniture, valuables and other belongings away from the water, provided you can do this without stepping into water or handling wet electrical items.

• Use towels to catch small drips on the floor, but don’t climb a ladder or reach towards a wet ceiling.

• Keep people away from any ceiling that is sagging, bulging, cracking or visibly changing shape. It could give way; don’t touch or puncture it.

If the water is coming from your own flat as well (for example, from a washing machine hose or a sink) you may be able to turn off your own water supply at the stopcock if you can reach it safely. This won’t stop a leak originating in the flat above, so keep trying to contact the upstairs resident and building contact.

Tell the people responsible for the building

Report the leak promptly to the person or organisation responsible for your home and building:

• If you rent: contact your landlord or letting agent.

• If you own a leasehold flat: contact your managing agent or freeholder, using the emergency contact details if available.

• If the upstairs flat is rented: the landlord or letting agent may also need to be told.

• If you’re unsure who owns or maintains the affected pipework: report the leak to the relevant contacts rather than waiting to establish responsibility.

The cause and the lease or tenancy arrangements can affect who is responsible for repairs. Don’t delay reporting while trying to work that out. The Leasehold Advisory Service explains how water leaks in leasehold flats can involve different responsibilities.

When you make contact, share the location of the leak, when you first noticed it, whether it is getting worse and whether water is near electrical fittings. If you leave a voicemail or send a message, include a contact number and ask for confirmation that it has been received. The Citizens Advice guide to reporting repairs also recommends reporting problems promptly and keeping a written record.

Make a clear record of what you can see

If it’s safe, take photos or short videos of the affected ceiling, walls, floor and belongings. Note:

• The time you first noticed the water.

• Which rooms or areas are affected.

• Whether the leak is steady, intermittent or getting worse.

• Who you contacted and when.

• Any action taken by the upstairs resident, plumber or building contact.

Keep messages, call records and receipts for reasonable emergency expenses. Avoid throwing away damaged belongings until you’ve spoken to your insurer, unless they present a safety or hygiene risk. A clear record can help the people arranging repairs and support any insurance claim.

Contact your insurer and arrange professional help

Check your home insurance policy or contact your insurer’s claims line as soon as practical. Ask whether you need to use an approved emergency plumber, whether the insurer will arrange leak detection, and what information they need from you. If the building has a block insurance policy, your managing agent or freeholder can advise how to report a potential claim.

Don’t attempt to repair pipework in another flat or open up the ceiling to find the source. A qualified plumber or the building’s appointed contractor can investigate safely. If electrics may have been affected, get advice from a qualified electrician before using those fittings or restoring power.

Before the first hour is up: Check that the situation is under control

Before you settle into waiting for repairs, make sure you have:

1. Moved people away from any unsafe area.

2. Alerted the upstairs resident and the relevant building or tenancy contact.

3. Asked for the water source to be stopped, if it can be done safely.

4. Reported any risk to electrical fittings or a changing ceiling.

5. Recorded what you can see and contacted your insurer or claims provider.

If water continues to come through, the ceiling changes or the leak reaches new areas, update the building contact immediately. Don’t assume the problem has been resolved just because the dripping slows; a plumber may still need to check the source and assess the affected areas.

Clear communication helps everyone respond faster

A leak between flats can affect residents, belongings and the wider building. Prompt reporting gives the right people a better chance to coordinate access, stop the source and arrange repairs.
