Plumbing and Drainage Repairs in Welsh Rental Homes

Plumbing and drainage faults are common in rental homes and can affect safety, heating, hot water and your ability to use essential facilities. This guide explains what tenants in Wales should expect from landlords, practical steps to report leaks, blockages or no hot water, and how to gather evidence if repairs are delayed. It covers when to contact your local authority or the First-tier Tribunal (Property Chamber) and the official forms you may need. Written for renters without legal training, the guidance uses plain language, shows realistic examples of communication and documentation, and explains timescales so you can act confidently to protect your home and health.

Who is responsible for plumbing and drainage?

In most standard assured and short-hold tenancies the landlord must keep the structure and exterior, including pipes, drains and water supply, in repair under the statutory obligations in the Housing Act 1988.^[1] Other historic statutes such as the Rent Act 1977 may apply in limited cases where different tenancy types exist.^[2] If repairs affect habitability (for example loss of heating or hot water) the landlord should act promptly and arrange qualified contractors.

Immediate steps for tenants

• Turn off the water supply and isolate the leak where it is safe to do so to limit damage and risk.
• Report the problem to your landlord in writing (email or text) and note the date and time of the report so there is a clear record.
• Take dated photos and videos of leaks, blockages and any resulting damage as evidence for later communication or applications.
• If there is a health or safety risk (no heating, sewage backup) contact your local authority housing team for advice and possible enforcement.

If your landlord doesn't act

If reasonable time passes after you report a repair, you can escalate. First remind the landlord in writing and set a reasonable deadline. If there is still no response you can ask your local authority to inspect for housing hazards or consider an application to the First-tier Tribunal (Property Chamber) for remedies such as orders or rent adjustments.^[3]

• Send a formal written complaint, keep a copy, and state a clear deadline for repairs so you can prove you gave an opportunity to fix the issue.
• Keep records of any inspections or access arrangements and ask the contractor for a report; this helps show the nature and urgency of the fault.
• Consider enforcement by the local authority or an application to the tribunal if the landlord refuses to act.

Official forms you may need

• Form RR1 — Rent Repayment Order application. Use this when a landlord has committed certain offences (for example failing to licence a property or serious disrepair) to seek repayment of rent; for example, you might apply after repeated failures to fix drainage that left the property uninhabitable.^[4]
• Form N5 — Possession claim (county court) used by landlords seeking possession; tenants should be aware of this form as a procedural document and can use the same filing routes to defend a claim if repairs or retaliation are relevant to their defence.^[5]
• First-tier Tribunal application guidance — official advice on how to apply, what evidence to include and fees; use this when you need a legal determination about repairs, rent adjustments or related disputes.^[3]

Evidence and preparing a case

• Keep a repair log with dates, times, names of people you contacted and their responses; this shows attempts to resolve the issue.
• Save receipts for emergency repairs, alternative accommodation or replacement items damaged by leaks.
• Collect contractor reports, council inspection notes and correspondence from the landlord to build a clear timeline.

FAQ

Who repairs internal pipes and blockages in a rented home?

Generally the landlord is responsible for the structure and installations, including internal plumbing and drainage. Tenants should notify the landlord promptly and follow up in writing. If the landlord fails to act you can contact the local authority or seek tribunal help.^[1]

What counts as an emergency repair?

Emergency repairs include complete loss of water, major leaks causing flooding, sewage backups or loss of heating in cold weather. In an emergency, isolate the problem if safe, report to the landlord immediately and, if needed, contact the local authority for urgent inspection or support.

Can a landlord enter to carry out plumbing repairs?

Landlords should give reasonable notice before entering except in genuine emergencies. Tenants should agree reasonable times for access and keep records of consents and visits.

How-To

1. Contact your landlord immediately by phone and follow up in writing with a clear description of the fault and your preferred times for access.
2. Document the issue with dated photos, videos and a short written timeline of events and communications.
3. Allow reasonable access for inspections and repairs while keeping a record of who attended and any reports provided.
4. If the landlord does not act, report the hazard to the local authority housing team and consider applying to the First-tier Tribunal (Property Chamber) with your evidence.^[3]
5. Continue to pay rent unless advised otherwise by an official body and seek advice from an official source before withholding payments.
