What to do right now — before the plumber arrives
Turn off your stop tap immediately. In most Lewisham properties it sits under the kitchen sink or where the supply pipe enters the building.
If you’re in Bellingham or Downham and can’t find it under the sink, check the front garden for a concrete cover marked ‘W’ or ‘S’ — many LCC cottage estate properties in SE6 share an external isolation point between two houses. If the external stop tap is required, access is typically via the pavement boundary box.
If water is near electrics, isolate the affected circuit at the consumer unit. If you can’t isolate safely, turn off the mains.
Move valuables and furniture away from spreading water. Open taps to drain the system pressure down faster.

Victorian pipework in SE4, SE13 and SE23 — why Lewisham pipes burst
Lewisham’s pre-1914 terraces in Brockley, Ladywell and Forest Hill carry original or partially updated pipework that has been under hard water stress for over a century.
Hard water in Lewisham contributes to scale build-up inside pipework over time.¹ Scale can reduce internal pipe diameter over time and may contribute to system stress alongside factors such as corrosion, pressure changes and freezing.
Lead supply pipes are still found in unmodernised SE4 and SE23 stock — these are the pipes running from the property boundary into the home, and are the homeowner’s responsibility. (The communication pipe, from the water main in the street to the outside stop valve at the boundary, is Thames Water’s responsibility.) Lead is softer than copper and less tolerant of pressure changes — joints in older lead pipework are more prone to failure under modern system pressures.
A burst lead supply pipe needs a plumber who understands transition couplings — a standard plastic push-fit repair on a lead pipe will not hold. A plumber attending a burst on a lead supply pipe should also advise on permanent lead replacement as the correct long-term solution; Thames Water’s Customer Side Lead Pipe Replacement scheme may support replacement of the communication pipe where eligibility conditions are met.⁵
External wall pipework in SE4 Victorian terraces is particularly vulnerable in cold weather. Poorly lagged pipes on external walls freeze and burst when temperatures drop overnight. A verified plumber attending a winter burst in Brockley should check lagging as part of the repair.
Frozen pipes — the specific Lewisham winter risk
Lewisham’s Victorian terraces carry pipework routes that put supply pipes in vulnerable locations — through unheated loft spaces, along external walls and under suspended timber floors with cold air circulation beneath.
When temperatures drop below zero, these routes freeze. The burst often occurs at a weak point downstream of the freeze — not where the ice forms. Pressure builds behind the ice blockage and fails the pipe at its most vulnerable point, which is often a joint or a thinned section some distance away.
If you suspect a frozen pipe rather than a burst, do not attempt to thaw it with a blowtorch or direct heat source. Apply gentle heat with a hairdryer, working from the tap end back towards the coldest section — this reduces the pressure surge risk as ice melts.
If you can’t locate the frozen section or the pipe has already burst, isolate at the stop tap and call a verified plumber.
Post-war estates in New Cross and Bellingham
Post-war properties in New Cross SE14 and Bellingham SE6 carry pipework from the 1960s and 1970s in some cases.
Older copper pipe in this stock is prone to pinhole bursts where scale and internal corrosion have been working on the pipe wall for decades. A burst in a New Cross flat may also originate in shared pipework — establish quickly whether neighbouring properties are affected, as this determines whether you or your managing agent instructs the repair.
High rental density in New Cross means burst pipe damage in deferred-maintenance properties can be significant before anyone notices. Significant water damage and resulting excess cold may be assessed as hazards under the Housing Health and Safety Rating System (HHSRS), depending on severity.²
Your insurer — what to do after the burst
Call your insurer as soon as the immediate emergency is contained. Most buildings insurance policies cover burst pipe damage — but the scope of cover varies.³
Take photographs before any remedial work starts. Document the damage, the pipe location and any visible cause. Your insurer may require a written report from the attending plumber.
Trace and access cover — if included in your policy — covers the cost of locating and exposing a concealed burst. Check your policy before authorising any opening up of walls or floors.

Frequently asked questions — Burst Pipes Lewisham
Turn off the stop tap immediately — under the kitchen sink or where the supply enters the property. Isolate electrics if water is near any fittings. Open taps to drain remaining pressure. Move valuables away from spreading water. Then call a verified plumber.
A burst in a pre-1914 Brockley property may involve lead pipework — confirm this with your plumber before any repair starts, as the correct technique differs from copper repair. Ask about permanent lead replacement as the long-term solution.
If the burst is within your demise — your internal pipework — it is your responsibility. If it originates in shared pipework, the freeholder or managing agent carries responsibility.
Contain the damage first, then determine responsibility. If you are a tenant, your landlord carries the repair obligation under the Landlord and Tenant Act 1985 (s.11).⁴
Most buildings insurance policies cover damage caused by a burst pipe.³ The repair to the pipe itself may or may not be covered depending on your policy wording.
Take photographs before any remedial work starts and contact your insurer as soon as the immediate emergency is contained. Check whether your policy includes trace and access cover — this matters if the burst is in a concealed pipe run in a Forest Hill SE23 or Brockley SE4 Victorian terrace.
Seized stop taps are common in Lewisham’s older stock — scale and corrosion lock the mechanism over time. If the stop tap won’t move, call a verified plumber immediately.
If needed, they can isolate at the external stop tap in the pavement boundary box outside the property. If access is not possible, the water supplier may need to be contacted.
Identify the most likely frozen section — typically where pipework runs through an unheated loft, along an external wall or under a suspended floor. Apply gentle heat from a hairdryer, working from the tap end back towards the coldest section. Never use a blowtorch.
Remember — the burst typically occurs downstream of the freeze at a weak joint or thinned section, not at the ice itself. If you can’t locate the frozen section, isolate at the stop tap and call a verified plumber.
