What general plumbing covers

General plumbing is the broad middle ground between an emergency and a specialist installation — the jobs most homes need a few times a year.

That includes leaks, overflows, low pressure, passing or seized valves, traps, wastes, appliance connections and small installations. On a leak call, the plumber checks whether the meter moves with outlets closed, then isolates fixtures and visible branches before opening finishes. On an overflow, the water level, float or fill valve, expansion route and warning pipe are checked. On low pressure, the incoming valve, local restrictions and — in a block — any communal tank or booster are considered. Accessible repairs may be completed on the first visit; hidden routes, specialist parts or drain defects can require trace-and-access, parts ordering or a separate survey.

Where a job turns out to be a specialist one — a gas boiler, a full bathroom, hidden-leak tracing, a drain that needs a survey — the honest answer is to route it to the right trade, and the specialist pages above do exactly that.

Know what’s yours — and Streatham’s quirks

The most useful thing to establish on any plumbing job is which side of the boundary it’s on.

Thames Water is responsible for the water main and communication pipe up to the boundary, while the private supply pipe and internal installation are normally the owner’s responsibility.¹ In rented homes, responsibility depends on section 11 duties, ownership, tenancy terms and cause: tenant-owned appliances and tenant damage are not automatically the landlord’s. A private drain serving one property is normally private, while a lateral or shared drain may be Thames Water’s even inside the boundary.²

Thames Water confirms that Streatham has hard water,³ so limescale can affect particular potable-water components, but corrosion, wear, adjustment and installation faults must be diagnosed separately. Converted houses may retain one incoming supply divided between flats; purpose-built blocks can rely on communal tanks, boosters and locked risers controlled by a managing agent. Those arrangements change who can isolate the water and who must authorise access.

If you rent, report the fault through the responsible landlord or provider, but liability depends on the fitting, cause and tenancy terms. Lambeth Council tenants use their tenant account or the out-of-hours emergency line 020 7926 6666;⁴ housing-association tenants use the provider’s repairs line, and private tenants notify the landlord or agent. A tenant-owned appliance or tenant-caused damage may follow a different route.

Streatham town centre & High Road (SW16) — an above-shop leak or appliance isolation may require access to the commercial unit below, while the stop valve or riser may be controlled by the block manager.

Streatham Hill (SW2/SW16) — converted houses and mansion blocks can retain one incoming supply divided between flats, with older or undocumented isolation points requiring staged testing.

Streatham Common & Streatham Vale (SW16) — 1930s and interwar houses with gardens, outside taps and longer runs, where general work ranges from a dripping valve to a small install.

St Leonard’s & Streatham Wells (SW16) — in rented, council, housing-association or leasehold homes, locked service cupboards and repair authorisation can determine whether the plumber can complete the work on the first visit.

Frequently asked questions

The private supply pipe and internal plumbing are normally the owner’s responsibility, while Thames Water covers the main and communication pipe. In a rented or leasehold home, check the exact pipe section, ownership, tenancy or lease and cause of damage.¹

The internal stop tap may be under the kitchen sink, in a cupboard or in a communal riser. Knowing and testing it can reduce damage if it closes properly, but it may not isolate stored water, a communal supply or the heating circuit.

A general plumber handles everyday repairs and small installs. Gas boilers need a Gas Safe engineer, hidden leaks a leak-detection specialist, and full bathrooms or kitchens a fit-out — the routing links above point you the right way.

Responsibility depends on the installation, ownership, cause and tenancy terms. Landlords normally cover installations for water and sanitation that they provide; tenant-owned appliances, misuse or tenant damage may be treated differently. Council and housing-association tenants should use the provider’s repair route.

Valves can become stiff or pass water because of scale, corrosion, wear, damaged glands, lack of use or installation faults. The plumber checks whether the valve actually closes and whether replacement requires a wider shutdown before recommending an upgrade.

Why verified plumbers — not a general directory

General plumbing relies on clear diagnosis and routing: the plumber should identify the circuit, confirm isolation and explain whether the first visit can complete the repair or only make safe, order parts or refer a specialist.

Every listing is checked before going live and re-verified annually: we confirm the business is legitimately trading and verify the named contact, we check evidence of public liability insurance, and we confirm the plumber covers Streatham’s SW16 area before a profile is approved — and we keep an eye on customer feedback gathered from across the web. For water and fittings work you can also look a plumber up yourself on WaterSafe, the free, water-industry-backed national register; where a job involves gas we confirm Gas Safe registration directly with the Gas Safe Register.

Listed plumbers pay a flat monthly fee to be listed. What that fee never buys is the verification itself — every listing is checked on the same terms — and there’s no per-enquiry middleman fee, so your enquiry goes directly to the plumber. Profiles may be suspended or removed if credentials lapse or credible concerns are raised; see the full verification process →.
