What is legionella and why it matters
Legionella bacteria can grow in hot and cold water systems, cooling towers and infrequently used outlets. Tenants may notice discoloured water, a lack of hot water or visible plumbing problems; symptoms of illness usually take 2–10 days to appear. Landlords should assess risks and control measures following HSE guidance[1].
Landlord responsibilities in Northern Ireland
Under the Private Tenancies Act (Northern Ireland) 2022 landlords must keep the property in repair and provide a safe environment, which includes managing water safety and carrying out risk assessments where needed[2]. The Department for Communities operates the Private Tenancies Branch which handles some tenancy disputes and guidance for mandatory duties[3]. Tenants should ask for written confirmation of any inspections, repairs or risk assessments.
Official forms and templates
Key official documents tenants may need:
- Form: HSE legionella risk assessment template (no form number). Use this to note dates, temperatures and actions; for example, ask to see the completed checklist after a remedial visit. HSE guidance
- Form: Private Tenancies Branch application for dispute resolution (see Department for Communities website for the official application and guidance). Use the form if the landlord fails to carry out urgent risk-control measures and you need a decision. Private Tenancies Act 2022
- Form: Environmental health complaint (local council form). Contact your local council environmental health team to report immediate public-health hazards; keep a copy of any submission.
How tenants can spot and record risks
Simple checks and records help resolve problems quickly and protect health.
- Keep a dated log of discoloured water, low hot-water temperatures and any symptoms you or visitors suffer.
- Take photos or short videos of leaks, rust, or unused outlets and save messages to your letting agent or landlord as evidence.
- Report concerns promptly in writing (email or message) and ask for timescales and follow-up actions.
Action if your landlord does not act
If urgent controls are not taken, escalate stepwise: remind the landlord in writing, contact environmental health, and keep copies of all communication. Use the Private Tenancies Branch application if informal steps fail; include your records, photos and any professional reports.
