The law on plumbing

Statutory basis

General plumbing work in the UK has no dedicated statutory register or licensing regime of the kind that exists for gas or (for notifiable work) electrical installations. The relevant statutory framework that does exist is the Water Supply (Water Fittings) Regulations 1999, which controls the design, installation and maintenance of plumbing systems connected to the public water supply, to prevent waste, misuse, undue consumption or contamination of water. Regulation 5 requires that 'any person who proposes to instal a water fitting in connection with any of the operations listed in the Table' must give notice to 'the water undertaker that he proposes to begin work' and 'shall not begin that work without the consent of that undertaker,' UNLESS the work is carried out by 'an approved contractor' for certain listed fittings, in which case the notification requirement does not apply. This exemption structure implies non-approved persons can still legally carry out most plumbing work, provided the water undertaker is notified where required — there is no blanket prohibition on an unregistered person doing plumbing work.

Who may legally do this work

Any plumber may legally carry out plumbing work; there is no equivalent to the Gas Safe Register for general plumbing. Where a plumber does gas work (e.g. connecting a boiler), that specific element of the job requires Gas Safe registration under the separate GSIUR regime. WaterSafe describes itself as 'a free online directory and national accreditation body for competent and qualified plumbers, water supply pipe installers and other water services specialists in England, Scotland, Wales and Northern Ireland' — approved contractors on this register benefit from the notification exemption in regulation 5, and 'can perform certain work without notifying water suppliers,' issuing 'Certificates of Compliance' instead. This is a voluntary accreditation route, not a legal requirement to trade as a plumber.

If you own and live in the property

  • A homeowner (or their plumber, on their behalf) proposing to install a water fitting covered by the Table in the Water Supply (Water Fittings) Regulations 1999 must give notice to their water undertaker before starting work, unless using an approved contractor for exempted fittings. Failure to do so, or installing non-compliant fittings, can be enforced by the water undertaker.

  • Where a homeowner's plumbing work also involves gas (e.g. connecting a new boiler or gas cooker), that part of the job is subject to the same Gas Safe registration requirement as any other gas work, regardless of who is described as the 'plumber' doing the wider job.

If you’re a landlord

  • No plumbing-specific statutory duty distinct from a landlord's general repairing obligations (e.g. under the Landlord and Tenant Act 1985, and the general safety duties summarised on gov.uk's landlord safety responsibilities page) was found in the sources checked. Landlords' gas-connected plumbing work (boilers, gas pipework) falls under the gas safety regime; landlords' water-fitting installations are subject to the same Water Supply (Water Fittings) Regulations 1999 notification rules as homeowners.

Certificates & records

  • Certificate of Compliance (Water Fittings Regulations)

    Who must hold it:
    Issued by a WaterSafe-approved contractor for exempted work under regulation 5
    Frequency:
    One-off, per job

    WaterSafe states approved contractors 'must comply with The Water Supply (Water Fittings) Regulations 1999 for every installation and issue a certificate stating that the work complies with the Regulations,' and are 'available to be audited periodically by the local water company.'

Commonly misunderstood

  • Myth vs fact

    Myth: Many homeowners assume plumbers must be licensed or registered by law, the way gas engineers and (for notifiable work) electricians are.

    Fact: There is no statutory licence for general plumbing in the UK. The only legal restriction that touches plumbing is the water-fittings notification regime (regulation 5) and, separately, the Gas Safe requirement for any gas-connected element of a job. WaterSafe and WIAPS accreditation are valuable quality signals precisely because they are voluntary rather than a floor set by law.

Penalties for non-compliance

  • No specific fine figure for breach of the Water Supply (Water Fittings) Regulations 1999 was found in the sources checked today. The regulation-5 text itself confirms enforcement operates through the water undertaker's consent mechanism (work must not begin without consent, which 'shall not be withheld unreasonably') rather than a named criminal penalty in the provisions reviewed.

How to check who’s legally allowed to do this

WaterSafe operates the national register of approved plumbers and water-fitting installers, allowing consumers to check a plumber's WaterSafe accreditation. WaterSafe also recommends checking that a plumber holds at least 'an NVQ Level 2 in Mechanical Engineering Services (Plumbing) or an equivalent plumbing-related qualification' and warns that 'over a quarter of people have been scammed by rogue plumbers.' A separate but related scheme, WIAPS (Water Industry Approved Plumbers Scheme), is administered by Water Regs UK on behalf of the water undertakers and is 'the largest of the four UK Approved Contractors' Schemes.'

Medium confidence

Some detail in this section could not be independently confirmed against a primary source at the time of checking — treat exact figures and edge cases as indicative, not guaranteed, and confirm anything material before relying on it.

Could not establish a specific statutory penalty figure for breach of the Water Supply (Water Fittings) Regulations 1999 from the provisions checked today; could not establish whether any London-specific water undertaker (beyond the general Thames Water service area) applies different notification thresholds.

Checked against the sources cited above on 21 July 2026. Rules and guidance change — always confirm anything material against the official source before acting on it.

Plumbing questions, answered

How quickly can a plumber come?
Response times depend on availability, location and job type. Non-urgent jobs are typically scheduled at a time that suits you; urgent jobs are triaged first.
Do I pay before or after the work?
You approve the price before work starts. Payment is handled securely through the platform when the job is done, so there's a full record of what was agreed and paid.
What should I include in my request?
The fixture involved, what it's doing, when it started, and a photo. 'Leaking' plus a photo of the pipe joint tells a plumber more than three paragraphs — it means they arrive with the right parts.
