In the first five minutes — what to do
Stop the water. Turn off the stopcock to cut the supply. In Victorian terraces across Peckham and Camberwell, the stopcock is often under the kitchen sink or in a hall cupboard — though locations vary by property.
In Bermondsey warehouse conversions, the isolation point is typically inside the unit at the meter cupboard. In purpose-built flats in Elephant & Castle and London Bridge, check near the front door or in a communal riser cupboard.
If water is near electrics — do not touch switches or electrical equipment if you are standing in water. Turn off the electricity only if it is safe to do so. Then call for help.
If you smell gas — do not touch any switches. Leave the property, call National Grid’s Gas Emergency line on 0800 111 999 and do not re-enter until cleared. Gas emergencies are not a plumbing matter — only a Gas Safe registered engineer can work on gas appliances or pipework.
Then call an emergency plumber from the listings above.
Drain responsibility in Southwark — before authorising any excavation work
Before authorising any drainage excavation, confirm who owns the drain.
Shared sewers that were transferred to Thames Water in 2011 — including those running under gardens and driveways — are Thames Water’s responsibility.
In Borough and Bermondsey, older clay drainage infrastructure is common in Victorian-era stock. If a drain in SE1 is not clearing with standard treatment, ask your plumber whether a CCTV survey is appropriate as part of their diagnosis.
Peckham and Camberwell: plumbing faults in Victorian terraces
Victorian terraces across SE15 and SE5 that retain original loft storage systems may rely on gravity-fed cold water supply from a loft cistern. Plumbing faults in these properties can include:
- Burst connections at the cold water tank in the loft
- Split overflow pipes
- Failed compression joints on older pipework
- Stopcock valves that have not moved in years and may be seized
Thames Water confirms hard water causes limescale build-up on fittings and appliances — which can affect valves and components over time.²
If the stopcock will not close, tell your plumber before they arrive — they can advise on isolation options.
Elephant & Castle and London Bridge flats: who owns the repair
In purpose-built flats and converted buildings around London Bridge and Bermondsey, water coming through your ceiling may originate from a shared riser or drainage stack. Responsibility depends on your specific lease and building configuration.
Contact your managing agent alongside calling a plumber. The plumber identifies the source and contains the damage. Responsibility for structural repair is determined by the lease, the freeholder’s obligations, and potentially the building’s insurer — confirm before authorising any structural or access work.
Private rented properties across Southwark SE postcodes
Southwark Council operates selective licensing across a significant number of wards in the borough. Check the official Southwark property licensing page to confirm whether a specific property is within a licensed area.³
Braided flexible hose connections between stopcock and appliance can fail and release water rapidly. Checking and replacing aged flexible hoses when a plumber attends for any other job is practical maintenance in Southwark’s hard water SE postcodes.

Turn off the stopcock — often found under the kitchen sink or in a hall cupboard in Victorian terraces across SE15, though exact locations vary.

Yes. Your landlord must address urgent plumbing problems that pose a risk — including flooding, leaks near electrics and loss of water supply.
Report the problem to your landlord first. If they do not respond, contact Southwark Council’s private tenant housing team.⁴
The council aims to respond the next working day to urgent problems reported against private landlords.
In a warehouse conversion or purpose-built flat in SE1 or SE16, water through the ceiling may originate from a shared riser or drainage stack — though responsibility depends on your specific lease and building configuration.
