What bathroom plumbing actually involves

A bathroom is the most plumbing-dense room in the house, and small mistakes show up as damp, smell or a failed inspection. On a first visit, the plumber should isolate and test each likely source before finishes are opened:

Suite swaps — bath, basin and WC replaced onto existing connections; straightforward when the layout stays put, and the seals, traps and soil connection are what make it leak-free.
Showers — a thermostatic mixer valve blends hot and cold safely and holds temperature when another outlet is used; before specifying one, the plumber should check static and dynamic pressure, flow and the hot/cold balance. On the water side it must be installed to the water regulations. An electric shower is a different animal — that’s an electrician’s job (below).
Backflow and fittings — under the Water Supply (Water Fittings) Regulations 1999, fittings must be of an appropriate standard and backflow protection matched to the assessed risk. A shower head that can drop into a bath needs protection appropriate to its design and use. Bidet backflow risk also depends on the design: a hose handset, ascending spray or outlet capable of becoming submerged normally presents a fluid-category-5 risk, while some conventional above-spillover designs may be category 3. The protection must match the category assessed by the water undertaker.¹
Traps and wastes — every bath, basin and shower needs a trap holding a water seal to keep drain smells out; a common refit fault is a trap that’s too shallow or a waste run with the wrong fall. Staining beneath a shower can come from the tray seal, waste connection, supply or concealed valve, so each should be tested before finishes are removed. Accessible seals and connections can often be repaired on the first visit; concealed faults may require agreed access through walls, floors or boxing and separate making-good.
Hot-water scald safety — for a fixed bath in a new dwelling (including one created by a change of use), Approved Document G limits delivered water to no more than 48°C, usually via a thermostatic mixing valve; in an existing home it’s optional but sensible where the very young or elderly bathe.²

Moving the layout? Relocating a WC, basin or bath onto a new drainage connection — rather than reusing the existing soil and waste points — is altered drainage. Under the Building Regulations and building-control regime, new or materially altered drainage may require Building Control notification or approval, depending on the controlled work involved; Approved Document H provides technical guidance on compliance.³ Confirm the route with the relevant building control body before work begins.

Hard water, WC moves and where plumbing stops and electrics start

Three things shape bathroom work in Putney: the hard water, the borough’s building stock, and the plumbing/electrical boundary that trips up so many refits.

Hard water attacks the moving parts. Thames Water classifies all its supply as hard,⁴ and in a bathroom that means limescale on thermostatic shower cartridges, mixer valves and shower heads — the parts that then stick, drip or lose temperature control. Quality valves and accessible isolation points pay off over a refit’s life.

The electrical line is not the plumber’s to cross. A bathroom contains a legally defined electrical special location under Part P, and BS 7671 Section 701 applies zone, IP-rating and RCD requirements. A new circuit is notifiable; an addition or alteration to an existing circuit is also notifiable when it falls within the defined special location around a bath or shower. Like-for-like replacement, repair and work outside that special location may be non-notifiable, but must still comply with Part P and BS 7671.⁵ An electric shower, extractor fan, shaver socket or bathroom lighting is electrical work; the notification route depends on the scope and location, and a plumber should coordinate with a suitably qualified electrician rather than wire it themselves.

Putney’s stock sets the difficulty. Riverside and town-centre flats may have wet rooms, concealed cisterns or services in managed risers. Responsibility for a communal supply, riser or stack is not automatic: the freeholder or block manager normally needs to confirm responsibility and authorise isolation or access. Tiled boxing and concealed-cistern panels can turn trace-and-access and making-good into separate agreed work. In a leasehold mansion block, permission and an isolation booking may be needed before opening a shared riser or stack. In a bathroom above a Putney High Street shop, the plumber may also need access approval, checks in the premises below and evidence for the freeholder, managing agent or insurer before opening finishes. Victorian or Edwardian conversions may share soil stacks, so a proposed WC move must be assessed against the actual drainage alteration. Council and social tenants should route bathroom repairs to Wandsworth Council, which manages its own stock (out-of-hours emergencies 020 8871 8999).⁶

Find a verified plumber by Putney district

Postcode coverage varies by listing — confirm yours when you call.

Putney Embankment · Lower Richmond Road · riverside (SW15) — some managed flats have wet rooms, concealed cisterns or high-pressure systems; the freeholder or block manager should confirm responsibility and authorise access to communal services.

Putney High Street · town centre (SW15) — flats above shops can have compact bathrooms; trap depth, waste fall, access approval and checks in the premises below may shape the job.

East Putney · West Putney (SW15) — conversions may have upstairs bathrooms sharing a soil stack; a WC move needs assessment to establish whether it creates controlled drainage work.

Putney Hill · West Hill (SW15/SW18) — in mansion blocks, communal supplies or stacks may require responsibility checks, permission and a booked isolation before a refit proceeds.

Putney Heath · Putney Vale (SW15) — in the mixed local stock, hard-water scale is one possible cause of sticking shower valves or cartridges and should be confirmed by inspection.

Frequently asked questions

Only if they are competent to undertake the electrical work and the applicable Part P notification and certification route is followed. Using a registered competent-person electrician is the usual route. A plumber handles the water side and coordinates with the electrician.

New or materially altered waste or drainage work may require Building Control notification or approval, depending on the controlled work involved. Reusing existing connections may not; confirm the specific proposal with the relevant building control body before work begins.

That 48°C limit under Approved Document G applies to fixed baths in new dwellings (including change-of-use conversions), not to a refit in an existing home — though a thermostatic mixing valve is worth fitting where very young or elderly people bathe.

Often a scaled thermostatic cartridge — routine in hard-water Putney — or pressure dropping when another outlet is used. A verified plumber can descale or replace the cartridge and check the system.

Bidet backflow risk depends on the design. A hose handset, ascending spray or outlet capable of becoming submerged normally presents a fluid-category-5 risk; some conventional above-spillover designs may be category 3. The protection must match the category assessed by the water undertaker. See Water Regs UK bidet guidance.

Why verified plumbers — not a general directory

A bathroom refit is where hidden leaks, wrong-fall wastes and the plumbing/electrical boundary all bite — so the credential that matters is a plumber who works to the water regulations and knows exactly where their job stops and a registered electrician’s begins.

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 Putney’s SW15 postcodes before a profile is approved. You can also look a plumber up yourself on WaterSafe, the free, water-industry-backed national register of approved plumbers.⁸ Profiles may be suspended or removed if credentials lapse or credible concerns are raised — see the full verification process →.

We charge plumbers a flat monthly listing fee; there’s no pay-to-play ranking and no per-enquiry middleman fee — enquiries go directly to the plumber.
