What counts as a plumbing emergency in Greenwich
A plumbing emergency is any fault that cannot safely wait.
Greenwich Council states that emergencies include very dangerous problems that could hurt people or damage property, and aims to respond within 2 hours.¹ For plumbing, this typically includes burst pipes, blocked drains and toilets causing flooding. Urgent but non-emergency faults — a leaking pipe you have isolated, a boiler fault in mild weather — can wait for a same-day or next-morning booking at standard rates.
Not every urgent job is an emergency — and not every emergency looks dramatic. A slow drip under a floorboard in a Charlton terrace can cause serious timber damage if left unaddressed. A boiler making unusual noises on a cold night may justify same-day advice, especially if accompanied by loss of heating or hot water, error codes, smells, staining, or any signs of unsafe operation.
If you are unsure, call a verified emergency plumber in Greenwich. A plumber will tell you whether it needs same-day attention.
Why plumbing risks vary across Greenwich homes
Two things shape Greenwich’s plumbing risk profile: the housing stock and the water supply.
Charlton (SE7), Greenwich and East Greenwich (SE10), and Woolwich and Plumstead (SE18) each contain different older housing patterns, with Victorian and Edwardian terraces concentrated in Charlton and Plumstead, and Georgian and Victorian stock in Greenwich and East Greenwich. Older terraces in Charlton and Plumstead may still have ageing internal pipework and older private drainage runs. Thames Water advises that homes built before 1970 may have lead supply pipes. Age-related failures do not follow a calendar.
Cold weather places particular demands on older plumbing — pipework can be exposed in older terraced houses where it runs through lofts or unheated voids, and burst pipes in these locations are more likely during cold spells. Boilers that have not fired since spring can also reveal faults the moment they are needed.
Hard water across Greenwich’s SE postcodes
Thames Water says most water in South-East England is hard.² Limescale builds inside pipes, on boiler heat exchangers and around shower valve cartridges. Scale on a heat exchanger can reduce boiler efficiency over time. The Health and Safety Executive advises that all gas appliances, flues and pipework should be regularly maintained and serviced at least annually by a Gas Safe registered engineer.⁴
Shared drainage in Greenwich’s terrace streets
Victorian terraces in Plumstead, Charlton and Blackheath may share drainage between neighbouring properties. Thames Water is responsible for shared sewers serving multiple separate properties, even where they run under private gardens.³ The pipes serving only your property remain your responsibility. If multiple properties are affected by the same drainage fault, the issue is more likely within shared drainage rather than a private pipe — contact Thames Water before commissioning private work.
In converted Victorian houses and purpose-built flats — both common in parts of Greenwich and Woolwich — internal soil stacks are normally a building, freeholder or lease issue rather than a Thames Water public sewer issue. Check your lease or contact your managing agent. If a drain backs up in a flat and your neighbour is unaffected, the fault is likely in the shared internal stack, not the public sewer.
What to do before the plumber arrives
Locate your stopcock — also called the internal stop valve — first. It is often found under the kitchen sink, but in older Greenwich properties it may also be in an airing cupboard, under the stairs or near the front door. If the internal stopcock is seized — more common in older properties — the external stop valve in the boundary box or pavement is the next option. Your plumber can locate it.
Turn off any electrical supply near the water source — if safe to do so.
Take a short video of visible damage before the plumber arrives. It speeds up diagnosis and supports any insurance claim.
If your boiler shows signs of unsafe operation — yellow or orange flames, soot or yellow staining around the appliance, a pilot light that keeps blowing out, a smell of gas, or signs of fumes in the room — stop using it immediately. These are signs of incomplete combustion or potential gas escape, and HSE guidance states gas appliances should not be used if you suspect they are unsafe.⁴ Turn the appliance off and do not restart it until a Gas Safe registered engineer has assessed it.
Modern combi boilers display error codes when sensors detect a fault. Some codes indicate component failures that don’t pose immediate safety risk; others — particularly those relating to combustion, flame failure, flue or seals — may indicate gas-safety issues. Check the code against the manufacturer’s manual where possible, and have a Gas Safe registered engineer assess the appliance if the code relates to gas or combustion safety, or if the boiler will not operate safely.
Emergency callouts follow two stages: containment is the immediate priority to stop active damage, then full repair either on the same visit or once parts are confirmed.
What emergency plumbing costs in Greenwich — 2026
Typical London 2026 ranges. Actual costs vary by property type, access and provider. No official pricing data exists for private emergency plumbing — always obtain multiple written quotes before work begins.
| Service | Typical London range 2026 |

| First-hour labour | £65–£105 |
| Burst pipe repair (all-in) | £260–£320 |
| Typical emergency job (resolved within 2 hours) | £200–£320 |
| Parts | Quoted separately |
Most emergency attendances involve a callout fee and labour charged on top. Some providers use an all-inclusive hourly rate — confirm the pricing structure before the plumber arrives. Parts for common faults are carried on most vans. Specialist boiler components may require a next-day return — your plumber confirms this before leaving.
FAQ
Most plumbers listed here cover Greenwich as a primary area. For SE3, SE7, SE10 and SE18, many aim to respond as quickly as possible for genuine emergencies — confirm expected timing when you call.
Calling is always faster than messaging.
An emergency callout means immediate attendance — the plumber drops or delays other work to reach you. Emergency attendances involve a callout fee plus out-of-hours rates where applicable. A standard booking is pre-scheduled at a lower rate.
Active flooding, a water leak you cannot stop, or a boiler showing signs of unsafe operation warrants an emergency callout. A tap that has dripped for three weeks does not.
Containment is the immediate priority. Full repair depends on parts availability. Boiler components may require a next-day return if not carried on the van.
Your plumber confirms exactly what is completed and what is scheduled before they leave.
Work guarantees available — confirm the terms with your plumber before work starts and ask for a written job sheet on completion.
Yes. Age of the property, boiler type (combi or system), stopcock location if you know it, and any history with this pipe or drain.
If you share drainage with a neighbouring property — common in Victorian terrace streets across Plumstead, Charlton and Woolwich — mention it. It saves diagnosis time on arrival.
