Coverage: SW17 (Tooting, Tooting Bec, Upper Tooting, Furzedown) and the edges into SW12 (Balham), SW16 (Streatham), SW19 (Colliers Wood) and the CR4 (Mitcham) boundary — Tooting Broadway, Tooting Bec, Totterdown Fields, the Heaver Estate and Amen Corner.
What this covers: full bathroom, en-suite and wet-room installs; bath, basin, shower, WC and cistern work; supply and waste runs; unvented hot-water systems requiring specific competence and the appropriate Building Regulations certification or Building Control route; bathroom electrical coordination; waterproofing interfaces; and leak diagnosis.
Not sure which page you need? Only the taps → Tap Repair & Installation; only the WC → Toilet Repairs; a hidden leak you can’t trace → Leak Detection; a small odd job → General Plumbing.
Costs: most work is quoted per job — see What it costs ↓ for an editorial estimate.
Availability: each verified listing sets its own hours and lead times — a full re-fit is usually booked in advance, a leak sooner.
What a bathroom job actually involves
A bathroom project starts with a survey of the existing supplies, static and dynamic pressure, hot-water capacity, soil-stack position, waste fall, floor construction and service access. The plumber can then confirm whether the proposed shower will perform and whether a WC or island-style layout can discharge by gravity. Moving a WC far from the stack may be impractical or require a pumped solution with additional noise, maintenance and access. Supply and waste joints should be tested before boxing, tiling or ceilings conceal them.
Waterproofing must have a named responsibility. The plumber should define the plumbing penetrations and testing; the tiler, waterproofing specialist or main contractor should specify, install and warrant the tanking system unless the plumber has expressly taken that scope. Commissioning should include supply-pressure tests, waste-flow tests, any required waterproofing or flood test, operation of valves and traps, and confirmation that concealed components remain serviceable.
Two compliance areas need clear routes. Work on an unvented hot-water storage system must be designed and installed by a person competent in that work. It must either be self-certified through an applicable competent-person scheme or dealt with through Building Control; notification does not remove the need for competence.1 Bathroom electrical work must comply with Part P and BS 7671. Notifiable work—such as a new circuit or work within the defined special-location zones—must use an accepted competent-person, third-party certification or Building Control route.2 Water fittings also require installation-specific backflow protection, and specified work such as a bath over 230 litres requires advance water-company notification.3
Tooting homes, hard water & conservation rules
The property and proposed work should be checked at the address rather than inferred from the district. A Broadway flat may have a tightly boxed service duct and shared soil stack; a converted terrace may have a bathroom added away from the original stack; and external soil-pipe changes in a conservation area may require an address-specific planning check. The Totterdown Fields and Heaver Estate material should be checked against the exact property and proposed external alteration.45
Thames Water confirms that the regional supply is hard, so limescale may affect showerheads, aerators, thermostatic cartridges, glass and hot-water components; the rate of build-up depends on use, temperature and maintenance and should not be stated as a fixed local timetable.6 For a new dwelling or one formed by the relevant material change of use, Approved Document G limits hot water to a fixed bath to 48°C; outside that statutory scope, a thermostatic mixing valve may still be selected as a safety measure.1
Find a verified bathroom plumber by district
Tooting Broadway (SW17) — flats above shops and other homes, where a bathroom leak can damage the premises below and permanent work on a shared stack or service duct may need managing-agent authority.
Tooting Bec & the Heaver Estate (SW17) — before specifying a shower or additional bathroom, the plumber checks static and dynamic pressure, available hot-water capacity, floor construction and the route to the existing soil stack; external changes are checked against the exact address.
Totterdown Fields (SW17) — compact layouts and existing stack positions can limit where a WC or shower can move; any proposed external soil or waste pipe alteration needs an address-specific planning check.
Furzedown & Upper Tooting (SW17) — converted terraces may have bathrooms added away from the original stack, so pressure, hot-water capacity, gravity fall and permanent access to concealed valves and traps are checked before the layout is agreed.
Converted flats (SW17-wide) — the soil-stack position can prevent the proposed WC location, and communal alterations or leaks into another unit require the lease, freeholder and managing-agent route to be checked.

Editorial estimate only, to help you sense-check a quote — these are NOT regulated rates, NOT market data, and NOT a published cost survey. Always agree the price and what’s included before work starts. See How to read a plumbing quote and the London plumbing costs guide.* Tooting is inside the London-wide ULEZ but outside the central Congestion Charge zone, so a non-compliant vehicle may incur the daily ULEZ charge.7
Frequently asked questions
For most like-for-like bathroom plumbing in an existing home, a separate Building Control application may not be needed. An unvented hot-water system must still be installed by a competent person and either self-certified through an applicable competent-person scheme or dealt with through Building Control. Electrical work must comply with Part P and BS 7671; notifiable work needs an accepted certification or Building Control route.
Internal work is generally fine, but on Totterdown Fields and the Heaver Estate the Article 4 Direction means external changes — soil pipes, windows, the building’s appearance — can need planning consent. Check the address with Wandsworth before external work.
Only to new dwellings or homes formed by a change of use. In an existing home it isn’t required, though a thermostatic mixing valve is worth considering for a family bathroom.
Hard water can leave limescale on brassware, showerheads, glass and thermostatic cartridges, but the amount and timing vary. Choose serviceable fittings and follow the manufacturer’s cleaning guidance rather than assuming damage or a fixed timescale.
If the source is visible, the bathroom plumber can isolate and repair it, then test the room and the ceiling or premises below. If water is tracking or the source may be communal, use leak detection and involve the landlord, freeholder or managing agent before concealed access or stack work.
One contractor may coordinate the project, but the scope must identify who is responsible for plumbing, waterproofing, electrical work, finishes and certification. Electrical work must be competent and Part P/BS 7671 compliant, using the appropriate notification or certification route where required.
The contract should name the person who specifies, installs, tests and warrants the waterproofing system. Do not assume it belongs automatically to the plumber or tiler. Plumbing penetrations, tanking, flood testing and making-good should be separated clearly before work begins.

Why verified plumbers — not a general directory
A bathroom hides its plumbing behind tiles and boxing, so the credential that matters is proof the person doing it is who they say and is insured for it. Every listing here is checked before it goes 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 Tooting’s SW17 postcodes before a profile is approved. Where a bathroom touches drinking-water fittings you can look a plumber up on WaterSafe, and where it involves gas we confirm registration with the Gas Safe Register. Profiles may be suspended or removed if credentials lapse or credible concerns are raised — see the full verification process →. No customer middleman fee: enquiries go directly to the plumber, with no pay-to-play ranking.

Whether it’s a full re-fit in a Tooting Bec terrace, an en-suite in a Heaver Estate house, or a leak fix in a Broadway flat, the bathroom is the part of the job that has to be sound before the tiles go on — and in Tooting’s conservation areas, external changes need checking first. The verified plumbers above cover SW17 and the Tooting edges, with identity, insurance and, where relevant, Gas Safe registration checked.
