Right now: stop the water
Before anything else, isolate the water at your internal stop tap if you can find it and turn it. The stop tap is usually:
- Under the kitchen sink.
- In a downstairs cupboard near the front of the property.
- In a cellar or basement, often near the front wall on a Victorian or Edwardian terrace.
- In a hallway or porch in some flats.
Turn clockwise until tight. Run a cold tap downstairs to drain pressure from the system once the stop tap is closed.
If the stop tap is seized (common in older properties), don’t force it. If you cannot find or operate the internal stop tap, the next isolation point is the outside stop tap (the property of your water authority — Thames Water or SES Water — and intended for emergencies, not routine isolation), usually near the property boundary under a small metal cover, sometimes on the pavement.
If water is escaping near electrical fittings, sockets, or the consumer unit, see Electrics and water below.
For a step-by-step walk-through of locating and operating your stop tap, see our Find Your Stop Tap guide.
Once the water is isolated, contact a directory-listed plumber and explain what has happened, what you’ve isolated, and whether electrics, gas appliances or shared pipework are involved. The plumber’s call-handler will agree priority and confirm response time, call-out fee and pricing on the call.
Safety first
Gas emergency
Smell gas, hear hissing or suspect a gas leak. Do not switch anything on or off, and do not use flames, electrical appliances, or smoke.
Open doors and windows if it is safe to do so. If you know where the gas meter emergency control valve is and can reach it safely, turn off the gas supply at the meter. Leave the property if the smell is strong or you feel unsafe, then call the National Gas Emergency Service on 0800 111 999 (free, 24/7) from outside.¹
If you are unsure of the emergency control valve’s location or how to operate it, do not attempt to use it. Leave the property, ventilate as you go, and call 0800 111 999 from outside.
Under the Gas Safety (Installation and Use) Regulations 1998 (enforced by HSE), gas work on appliances, pipework, fittings or flues must be carried out by a Gas Safe registered engineer competent for that specific category of work, registered through the Gas Safe Register.⁵
Listing checks confirm Gas Safe registration against the Gas Safe Register database at the point of listing — they do not guarantee current registration or category competence on the day. Always verify the engineer’s licence number on the Gas Safe Register at booking and again on arrival, before any gas work begins, and confirm they are competent for the appliance category being worked on (for example, boilers as distinct from cookers).¹⁵
Electrics and water
Do not attempt to isolate electrics if there is any risk of contact with water. If water is reaching ceiling lights, sockets, switches or the consumer unit, isolate the property at the main consumer unit (the master switch) only if you can do so without standing in or contacting water.
If in any doubt, do not attempt isolation — leave the affected area and call 999 if anyone is at risk of electric shock.
Notifiable electrical work in dwellings — including new circuits, consumer unit replacement, and work in defined special locations such as the zones around baths and showers — must be carried out by a registered competent person or notified to building control under Approved Document P.³⁷
A plumber will isolate water and repair the leak; restoring electrics that have been damaged or are unsafe usually needs a separate registered electrician.
Carbon monoxide
A faulty, badly installed or poorly maintained boiler is one of the more common sources of indoor carbon monoxide (CO) exposure.¹⁷ If a boiler has been water-damaged, do not run the appliance until it has been checked by a Gas Safe registered engineer competent for that appliance category.
Under the Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022, private and social rented dwellings in England must have a CO alarm in any room used as living accommodation that contains a fixed combustion appliance other than a gas cooker; enforcement is by local authorities.³⁹
Owner-occupiers are not covered by the landlord alarm duty, but installing a CO alarm is a sensible safety measure. Follow the alarm manufacturer’s siting instructions. CO alarms certified to BS EN 50291 are widely available.
If anyone in the home develops symptoms — headaches, dizziness, nausea, confusion, or symptoms that ease when leaving the property — open windows, leave the property, and call 0800 111 999 so the supply can be made safe before any boiler work resumes.¹
Do not re-enter the property until the National Gas Emergency Service or a Gas Safe registered engineer has declared it safe. Then seek medical advice. If symptoms are severe or anyone has lost consciousness, call 999 first.
What counts as a plumbing emergency
Plumbing problems run a spectrum. Some need a plumber within the hour; others can wait until the next working day at a lower rate. The points below are for orientation — the plumber’s call-handler will agree priority on the call.
Genuine emergency, attend now:
- Uncontrollable burst pipe or escape-of-water you can’t stop at the stop tap.
- Ceiling leak from a flat above, escalating.
- Hot water cylinder burst flooding the airing cupboard or the floor below.
- No heating or hot water in cold weather, especially where vulnerable residents are affected.
- Sewer back-up flooding indoors or external manhole overflowing onto pavement / into the property.
- A boiler that’s been water-damaged or shows signs of a CO concern.
- Gas leak — call 0800 111 999 first; a plumber is not the right contact.
Urgent but can wait until business hours:
- Slow leak from a tap or fitting that’s contained.
- Boiler lockout in mild weather.
- Toilet that’s blocked, where there’s another working toilet in the property.
- Drain blockage that’s slowing but not yet flooding.
Standard appointment work:
- Tap replacement, fitting replacement, planned repair work, system servicing.
If you’re unsure where you sit on this spectrum, describe the situation when you call — most plumbers will give a clear callout/no-callout answer, and quote response time and charges before they leave.

What a directory plumber will do — and what they won’t
A plumber arriving for an emergency call will normally assess the situation, isolate water or gas as needed, make safe (temporary cap, isolation, drain-down), carry out the immediate repair where possible, and leave the system in a stable state with a clear plan for any follow-up work that needs a planned visit.
Many will give practical drying advice but most are not damp specialists or insurance loss assessors — that’s a separate workstream.
Directory-listed plumbers cannot:
- Repair public water mains, communication pipes outside the property boundary, or public sewers — those are the water authority’s responsibility (Thames Water for sewerage borough-wide; Thames Water or SES Water for water supply depending on your address).
- Carry out gas work on a boiler that has been water-damaged — only a Gas Safe registered engineer competent for that appliance category can assess and carry out any gas work.⁵
- Restore notifiable electrics damaged by water — that needs a registered competent person under Approved Document P.³⁷
- Force entry into communal stack risers in mansion blocks, converted-flat buildings or estate housing — for the converted Victorian houses common across Wimbledon and the post-war estate stock in Pollards Hill and St Helier, the building manager, freeholder, managing agent or housing association controls access to shared pipework.
Availability for out-of-hours emergency callouts varies by plumber. Confirm response time, call-out fee, and pricing structure when you contact them.
Water authority routing
Merton sits across two water-supply company areas:
- Thames Water supplies most of Merton, including Wimbledon, Wimbledon Park, South Wimbledon, Colliers Wood, Raynes Park and surrounding postcodes. Report a water-supply problem on 0800 316 9800 (free, 24/7).²
- SES Water (Sutton and East Surrey Water) supplies parts of Morden, Mitcham, Pollards Hill and bordering areas. Report a water-supply problem on 01737 772000 (24/7 emergency line).
Check your most recent water bill if you’re not sure which supplier covers your address.
Sewerage across the whole borough is Thames Water’s responsibility — even for properties supplied by SES Water. SES Water is water-only and does not handle sewers.
For burst pipes specifically, the responsibility split (internal pipework vs private supply pipe vs communication pipe vs public main) is set out in Thames Water’s pipe responsibility guidance and the equivalent SES Water guidance — the framework is the same; only the report-it number differs.²²
For sewer back-ups, public sewer surcharges, manhole overflows on the pavement or in the road, see Thames Water’s sewer pipe responsibility guidance — most lateral drains and shared sewers were transferred to Thames Water on 1 October 2011.³¹ Report on 0800 316 9800.
Merton-specific signals
Merton’s housing stock and street pattern shape emergency callouts across the borough. The borough sits in a hard-water area, and housing stock spans Victorian / Edwardian terraces in the west through 1930s suburban semis to interwar and post-war estates in the east and south.
The following observations are based on local trade experience and the borough’s confirmed area-by-area mix, not on official data.
Wimbledon and west Merton (SW19, SW20). Victorian and Edwardian terraces and semis dominate, with larger detached housing around Wimbledon Village and Copse Hill. Many houses have been converted into flats over the years, and the converted flats often share original drainage stacks and supply pipework that wasn’t designed for the resulting load.
Older pipework layouts mean burst pipes from scale-thinned copper are a recurring emergency profile, as are stack-side blockages affecting lower-flat residents in conversions.
Raynes Park and west Merton (SW20). 1930s suburban semis dominate. Plumbing systems are typically single-family with no shared stacks, but extensions and loft conversions over the decades have tied additional bathrooms and kitchens into systems originally designed for one of each.
Capacity-related slow drainage and the pipework join points between original and added work are typical attendance patterns.
Colliers Wood and South Wimbledon (SW19). Higher density near the Northern Line and retail areas, with a noticeable mix of older terraces alongside new-build flat developments. Modern apartment blocks have pressurised supply systems and modern materials; older terraces on the same streets have legacy pipework.
Density also means more shared drainage in flats — a single blockage can affect multiple residents.
Mitcham and east Merton (CR4). Interwar and post-war housing estates with consistent layouts built at scale. A meaningful share of housing here is in the borough’s selective licensing and additional HMO licensing wards — Figge’s Marsh, Graveney, Longthornton and Pollards Hill — and in the additional-only HMO licensing wards of Colliers Wood, Cricket Green and Lavender Fields.⁵⁰
Higher-density occupancy puts more demand on pipework that’s typical of the period.
Pollards Hill (CR4). Concentration of large estate housing, with planned drainage networks serving multiple properties. Shared lateral drains and stack risers serve flats and maisonettes in the post-war estate stock; access to communal pipework needs the building manager, freeholder or housing association before work can start.
Morden (SM4). 1930s suburban housing with standardised plumbing layouts typical of the period. The St Helier estate (interwar, partly in Sutton) brings large-scale planned housing with uniform systems. Mixed maintenance histories across private and social housing in the same streets.
Motspur Park and Lower Morden (SW20 / SM4). Low-density 1930s housing with individual systems and few shared drainage issues, predominantly family homes with extensions added over time.
Hard water across the borough. Wherever you are in Merton, hard water affects boilers, taps, hot water cylinders and pipework — scale builds inside heat exchangers, on tap aerators, and inside copper pipework over years. See our London Hard Water Guide.
Conservation areas. Merton has a number of conservation areas including (among others) the John Innes (Merton Park) and John Innes (Wilton Crescent) conservation areas, both of which are subject to Article 4 directions that restrict permitted development.⁵³
Routine internal emergency repairs don’t engage these controls. External works that affect visible elevations, listed fabric, or conservation-area constraints can; that’s a planned-work conversation rather than an emergency one.
Housing association tenants
Merton Council does not own any council housing. All the council’s former housing stock was transferred to a housing association in 2010, and social housing in Merton is now provided by housing associations such as Clarion (the largest) and others.⁵²
This means there’s no equivalent of a council emergency repairs line in Merton — emergency routing depends on which housing association is your landlord.
For housing-association tenants:
- Check your tenancy agreement or recent correspondence for your housing association’s emergency / out-of-hours line. Most major associations have their own 24-hour repairs number for genuine emergencies (uncontrollable leak, total loss of heating in cold weather, total loss of hot water, sewer flooding indoors).
- Directory plumbers cannot bill the housing association on your behalf.
- If you can’t reach your housing association in a real emergency, contain the situation as best you can (isolate water at the stop tap; isolate electrics if water is reaching them and you can do so safely) and contact them again as soon as the line opens.
If you are unsure who your housing association is: check the rent statement, your tenancy agreement, or the most recent letter you received about your tenancy.
If your housing association is not responding to a serious repair, Merton Council’s Tenants’ Champion can help you escalate.⁵¹ The council’s Housing Enforcement team can also intervene where housing-association repair failures meet the threshold for action.
For the council’s general housing-advice routing, see Merton Council — housing advice.
Leaseholders
If you own a leasehold flat in Merton — including a former social-housing flat now privately held — your lease sets out which works are your responsibility (typically internal pipework serving your flat alone) and which are the freeholder’s, managing agent’s or housing association’s (typically structure, exterior, and shared services).
Merton Council does not have a direct role in leaseholder repair disputes.
For an emergency inside your flat, a directory plumber can attend. For shared pipework, stack risers serving multiple flats, or external supply / drainage that affects the building, the freeholder or managing agent is the starting point — speak to them before booking work that affects shared fabric.
Private renters and landlords
If you rent privately in Merton, your landlord (or their managing agent) is normally the first contact for a plumbing emergency. Repair to the installation for water, sanitation and space/water heating is likely to engage Section 11 repair duties, for tenancies covered by Section 11 of the Landlord and Tenant Act 1985.¹³
In a genuine plumbing emergency, take action to make the property safe first (isolate water at the stop tap; if water is reaching electrics, isolate at the consumer unit only if safe to do so) and notify the landlord or agent in writing as soon as possible.
Tenants may be liable where damage is caused by misuse or breach of tenancy terms.
If your landlord is unresponsive and the disrepair affects health or safety, Merton Council’s Housing Enforcement team can investigate complaints about housing conditions including disrepair, damp, mould, dangerous conditions or absence of hot water.⁵¹
The council expects you to have notified the landlord first; only contact them once that has happened and the landlord hasn’t acted. The Tenants’ Champion can help you escalate where needed.
If your home is in one of Merton’s selective licensing wards (Figge’s Marsh, Graveney, Longthornton, Pollards Hill) or additional HMO licensing wards (those four plus Colliers Wood, Cricket Green, Lavender Fields), licence conditions include ongoing repair obligations, current gas safety records and CO alarms — non-compliance can be acted on by the council’s licensing team.⁵⁰
Landlords arranging an emergency repair should book directly with a plumber (Gas Safe registered for any gas work). Documenting the failure (photos, plumber’s invoice, dates) supports both the buildings insurance claim and any subsequent regulatory enquiry.
Gas safety duties for landlord-provided gas appliances, flues and pipework remain the landlord’s responsibility under the Gas Safety (Installation and Use) Regulations 1998 (regulation 36), and the annual Landlord Gas Safety Record must be kept up to date and provided to tenants.¹⁸
Selective Licensing and HMOs in Merton
Merton Council operates property licensing schemes that affect private rented homes, alongside the national mandatory HMO licensing scheme. Full scheme detail and the application portal are on Merton Council’s property licensing pages.⁵⁰
- Selective licensing (24 September 2023 to 23 September 2028): all single-family or two-sharer private rented homes in Figge’s Marsh, Graveney, Longthornton and Pollards Hill wards.⁵⁰
- Additional HMO licensing (24 September 2023 to 23 September 2028): smaller HMOs (typically three or four occupiers forming more than one household, sharing kitchen or bathroom facilities) in Colliers Wood, Cricket Green, Figge’s Marsh, Graveney, Lavender Fields, Longthornton and Pollards Hill wards, where the property is not already covered by the mandatory HMO licensing scheme.⁵⁰
- Article 4 directions for small HMOs (borough-wide). Planning permission is required to convert a property to a small HMO (Use Class C4) anywhere in Merton, via two Article 4 directions:⁵⁴
A plumber attending an emergency in a licensed rental will not enforce licence conditions — that’s the council’s role — but if the visit surfaces installation problems (out-of-date gas safety records, missing CO alarms, unsafe pipework, persistent disrepair), the landlord must address those issues to remain compliant.
Indicative emergency-plumbing costs in Merton

| Emergency call-out (evenings/weekends/bank holidays) | £150–£300+ |
| Hourly rate, business hours | £80–£120 |
| Hourly rate, evenings/weekends/bank holidays | £120–£200+ |
| Temporary isolation and made-safe | £80–£200 |
| Compression fitting or push-fit emergency repair | £100–£250 |
| Soldered copper repair (small section) | £150–£350 |
| Internal stop-tap replacement (emergency) | £150–£300 |
| Toilet pan removal to clear severe blockage | £150–£300 |

| High-pressure water jetting (per visit) | £200–£450 |
| Boiler emergency diagnostic and made-safe | £100–£200 |
| Hot water cylinder leak repair (where repairable) | £200–£500 |
These figures are based on typical London emergency plumbing call-out rates observed across independent contractors and directories — not regulated rates and not official market data.
We are not aware of official regulated pricing data for private plumbing rates, and no UK regulatory body publishes standard plumbing rates. Prices vary by access, materials, day and time of call, and the cause of the emergency.
Merton-specific cost factors that may push the figure up:
- Period property access. Pipework behind plaster, in cellars, or under fitted kitchens in Wimbledon and west Merton’s Victorian/Edwardian stock takes longer than open-access pipework.
- Hard-water-scaled copper. Borough-wide; where one pipe has failed because of internal scale, adjacent pipework is often in similar condition.
- Estate-housing coordination. Communal stack work in Pollards Hill, St Helier and other estate housing needs the housing association or building manager to authorise access.
- Out-of-hours seasonality. Cold snaps drive London-wide demand surges; expect higher rates and longer lead times.
- Converted-flat shared stacks (Wimbledon). A blockage or leak on a shared stack from a converted house can require coordination across multiple flats before clearance work can start.
The cost of drying out and making good ceilings, floors and decoration after an emergency is normally a separate workstream — handled by drying specialists and decorators, often via a buildings insurance claim.
Confirm the call-out fee, hourly rate, parts mark-up, and minimum charge when you contact the plumber.
Why directory-listed plumbers
Every plumber in our directory has been checked for identity, insurance, trading presence and Gas Safe registration where relevant before listing, and rechecked annually. Listing checks are administrative and do not replace user verification on the day.
We are not a regulator or certification body; our listing checks do not replace user verification on the day. For any gas-related work that arises (for example, a boiler check after a leak near the appliance), verify the engineer’s licence number on the Gas Safe Register at booking and on arrival, before any gas work begins, and confirm category competence for the appliance.⁵ ¹⁵
Some plumbers offer workmanship guarantees of 3, 6 or 12 months — look for the badge on the listing. Workmanship guarantees are set by individual plumbers and vary in scope; they are not standardised, and are not insurance-backed unless a plumber explicitly states otherwise.
Public liability insurance is not a statutory requirement for plumbers, but it is industry-standard and is often contractually required by clients, landlords, agents, blocks of flats or commercial sites. Evidence of public liability insurance was provided at the time of listing; users should confirm current cover with the contractor before booking.
Listing checks are completed before publication and repeated annually. Always confirm pricing, scope and call-out terms on the call before booking.

Closing
A plumbing emergency in Merton turns on three things: stopping the immediate damage (find your stop tap; isolate gas and electrics safely if needed), getting the right trade to the right problem (Gas Safe engineer for boilers; plumber for pipework; water authority for anything outside the property boundary), and managing the boundary with Thames Water or SES Water for anything beyond your private supply or sewerage.
Merton no longer has council-owned housing — housing-association tenants route through their association’s own emergency line; leaseholders book their own plumber for emergencies inside the flat with managing-agent involvement for shared fabric.
Confirm pricing, scope and call-out terms on the call — before any work starts.
