Plumber vs Gas Safe engineer — knowing the difference
For general plumbing — taps, toilets, waste pipes, supply pipes and water-based heating — a qualified plumber can carry out the work.
For any work on gas appliances, boilers, flues or gas pipework, Gas Safe Register confirms that all gas businesses and engineers must be on the register to carry out gas work legally.² HSE also confirms work on gas fittings must be carried out by a Gas Safe registered engineer qualified for the work in question.⁶ We always recommend checking an engineer’s Gas Safe registration number directly on the Gas Safe Register website before any gas work begins.
For drainage, Thames Water confirms property owners are usually responsible for waste drainage pipes within the property boundary that serve only their property.⁷ Thames Water is generally responsible for public sewers and lateral drains — including the section where a pipe serving only your property crosses the boundary and becomes a public lateral drain, and any shared sections of pipework. If your drainage issue may involve the section beyond your property boundary, confirm pipe ownership with Thames Water before commissioning work — a private drainage specialist may not be needed for sections that fall within Thames Water’s responsibility.
Water Fittings Regulations — what every Southwark plumber should meet
Regulation 4 of the Water Supply (Water Fittings) Regulations 1999 requires that water fittings are of appropriate quality and standard, suitable for the circumstances in which they are used, and installed in a workmanlike manner.¹
Regulation 3 states that no water fitting shall be installed, connected, arranged or used in such a manner that it causes or is likely to cause waste, misuse, undue consumption or contamination of water supplied by a water undertaker.⁸
These requirements apply to domestic water fittings within the scope of the Regulations, such as taps, WC cisterns, supply pipework and bathroom/kitchen installations connected to the public water supply. A competent plumber should ensure all work meets these requirements as standard.
Building regulations approval is not usually required for standard plumbing work or like-for-like replacements, but may be required where drainage is altered, electrical work is involved or structural changes are made.⁵
General plumbing in Southwark properties — what to know
Southwark’s housing stock is varied — Victorian and Edwardian terraces, purpose-built council estates, warehouse conversions and modern flats across SE1 to SE23 each present different plumbing considerations.
Southwark sits in Thames Water’s hard water area. Thames Water confirms hard water can leave behind a chalky residue called limescale on household fittings and appliances.³ In Southwark properties, limescale affects tap cartridges, shower valves, cistern mechanisms and appliance connections — and accelerates wear on components over time.
Southwark housing stock — practical context for plumbing work
The practical context of a plumbing job can differ widely depending on where in Southwark you are. The notes below are general observations to help frame a call to a plumber — your plumber’s site assessment will confirm what your specific property actually has.
Pre-1914 Victorian and Edwardian terraced stock — Peckham SE15, Camberwell SE5, Nunhead SE15, East Dulwich SE22, Dulwich SE21. Properties of this era can retain original or partially-updated supply pipework, older valves and fittings, and original or replaced cast iron drainage. If you have an older terrace and aren’t sure what’s behind the walls, mention this when you call — it helps the plumber bring appropriate fittings and isolation tools.
Bermondsey and Rotherhithe SE16 wharf and warehouse conversions. Conversions from former industrial buildings can carry adapted pipework where the original supply was reconfigured for residential use. Concealed pipework runs through floor slabs and behind structural masonry — useful to mention when describing the job.
Aylesbury Estate, Heygate replacement and Old Kent Road regeneration — Walworth SE17, Elephant & Castle SE17, Old Kent Road SE1/SE15. This area mixes pre-demolition stock with new-build replacement blocks. New-build flats may have heat interface units, pressurised supply systems and concealed plastic pipework in screed floors — worth mentioning the property type when you call.
Bankside, Borough and London Bridge SE1 mansion blocks and mixed-use buildings. Period mansion blocks above commercial parades can have varied internal layouts and shared risers. Your managing agent or block freeholder may have notes on the building’s plumbing configuration that help the plumber.
Southwark Council housing portfolio. Southwark Council manages a substantial portfolio of council housing stock directly. Council tenants should report repairs via Southwark Council’s repairs line on 0800 952 4444 — the council is responsible for installations for water in council-rented properties, including fittings, internal pipes and valves.⁴
Dulwich Estate and conservation areas — Dulwich SE21, East Dulwich SE22, Camberwell SE5, Peckham SE15. Conservation-area restrictions can apply to external pipework, visible plumbing changes and any work on listed or locally-listed buildings. Confirm with your plumber and check with Southwark Council planning whether any external work needs consent before instructing.
We recommend a site visit from your plumber before agreeing any scope that involves pipework re-routing, drainage alteration or work in older properties with original plumbing.
General plumbing for council tenants and private renters in Southwark
For council tenants, Southwark Council is responsible for installations for water in council-rented properties — including fittings, internal pipes and valves. Report repairs via 0800 952 4444.
For private tenants, under Section 11 of the Landlord and Tenant Act 1985 landlords are generally responsible for installations for the supply of water, gas, electricity and sanitation, and for space heating and heating water — subject to notice, access and responsibility for the defect.⁹ GOV.UK confirms landlords are responsible for repairs to sanitary fittings, including pipes and drains.¹⁰ Report faults to your landlord or agent in writing first. If they do not respond or take steps to arrange a repair, contact Southwark Council’s private sector housing enforcement team. The council aims to respond within 2 working days, or the next working day for urgent problems.⁴
