Water leaks are one of the most common issues in residential blocks of flats. Whether it’s a slow drip, a burst pipe, or water ingress from another flat, leaks can cause significant damage if not dealt with quickly.
This guide explains what to do if you have a leak, who is responsible, and how the issue is managed within a block of flats.
1. Immediate Action – What to Do First
If you discover a leak, it is important to act quickly to minimise damage.
Step 1: Stop the Water Source (If Possible)
Turn off your internal water supply using the stopcock
If safe to do so, isolate the affected appliance (e.g. washing machine, sink)
Step 2: Protect Your Property
Move furniture and valuables away from the affected area
Use towels or containers to catch dripping water
Step 3: Inform the Managing Agent Immediately
Report the issue to your block management company as soon as possible.
Provide:
Your flat number
Description of the issue
Photos or videos (if possible)
Whether the leak is ongoing
Prompt reporting helps prevent further damage and speeds up resolution.
2. Identifying the Source of the Leak
Leaks in blocks of flats can originate from various locations:
Your own flat
Another flat (above or adjacent)
Communal pipework
Roof or external structure
In many cases, the source is not immediately clear and may require investigation.
3. Who Is Responsible for the Leak?
Responsibility depends on where the leak originates and what the lease states.
A. If the Leak Originates from Your Flat
You are usually responsible if the issue relates to:
Internal pipework serving only your flat
Appliances (washing machines, dishwashers)
Bathroom or kitchen fittings
You will need to arrange repairs and may be liable for damage caused to other flats.
B. If the Leak Comes from Another Flat (e.g. Upstairs)
If you believe the leak is coming from another flat—particularly from above—it is important to act quickly and not rely solely on the managing agent to investigate.
Step 1: Contact the Occupier Immediately
Knock on the door of the flat where you believe the leak is coming from
Politely inform the occupier of the issue
If the property is tenanted:
Ask the tenant to contact their landlord or letting agent immediately
Request that they treat the matter as urgent
Your prompt action is important.
Step 2: Do Not Rely Solely on Others
Even if you have informed the neighbour:
Continue to monitor the situation
Take photos or videos of the damage
Keep a record of times and communication
Leaks can worsen quickly, so it is important to remain proactive.
Step 3: Inform the Managing Agent
Once you have contacted the occupier:
Report the issue to the managing agent
Provide details including:
Your flat number
The suspected source (e.g. upstairs flat)
Photos/videos of the leak
Whether contact has been made with the neighbour
The managing agent will:
Log the issue formally
Attempt to contact the relevant leaseholder or landlord
Arrange access if required
Coordinate further investigation or repairs
Important Points to Note
The leaseholder of the originating flat is typically responsible if the leak is due to their internal plumbing or appliances
Access may be required to stop the leak, and delays can increase damage
In urgent situations, emergency access procedures may be used
Practical Advice
Act quickly—delays can lead to significant damage
Communicate clearly with both the neighbour and managing agent
Keep written records of all communication
C. If the Leak Is from Communal Areas or Structure
The freeholder or management company is usually responsible if the issue relates to:
Roof leaks
External walls
Communal pipework
Shared systems
Costs are typically covered through the service charge.
4. Water Damage – What Happens Next?
Once the leak has been stopped, the focus shifts to damage and repairs.
Buildings Insurance
Most blocks have a buildings insurance policy which may cover:
Structural damage
Ceilings, walls, and floors (depending on policy terms)
Claims are usually handled by the managing agent.
Contents Insurance
Leaseholders are responsible for their own:
Furniture
Personal belongings
Internal decorations (in many cases)
You should contact your own insurer if needed.
5. Access to Flats
In some cases, access to another flat may be required to stop the leak.
The managing agent may:
Contact the leaseholder
Arrange access
Use emergency access procedures if necessary
This is particularly important if the leak is causing ongoing damage.
Common Causes of Leaks in Flats
Understanding common causes can help prevent future issues:
Failed pipe joints or fittings
Worn seals around baths and showers
Blocked or damaged drainage
Faulty appliances
Roof or guttering issues
7. Preventing Future Leaks
Leaseholders can take simple steps to reduce the risk of leaks:
Regularly check visible pipework
Maintain sealant around bathrooms and kitchens
Avoid leaving appliances running unattended
Ensure proper installation of washing machines and dishwashers
8. What If There Is a Dispute?
Disputes can arise where responsibility is unclear.
To resolve this:
Refer to the lease
Keep records (photos, emails, reports)
Communicate through the managing agent
Seek professional advice if required
9. The Role of the Managing Agent
A professional block management company plays a key role in managing leaks by:
Coordinating investigations
Appointing contractors
Liaising with leaseholders
Managing insurance claims
Ensuring compliance with the lease
Prompt communication and organisation are essential to minimise disruption.
