Legionella Risk Assessment for Scotland Landlords: Key Differences

If you let property in Scotland, your legionella duty sits inside the Repairing Standard — the statutory framework for private rented housing — and the Scottish Government's guidance is more prescriptive on a couple of points than the equivalent in England and Wales. The same UK-wide health and safety law applies, but Scotland adds specifics worth knowing: a stated two-year review interval and a requirement to flush the system before letting.

The short answer

Scottish landlords have a duty to assess hot and cold water systems for legionella, the same as landlords across Great Britain, under the Health and Safety at Work etc. Act 1974. What is different in Scotland is that the duty is reinforced through the Repairing Standard, and the Scottish Government's statutory guidance puts a number on the review interval where HSE's England-and-Wales guidance leaves it risk-based.

The Scottish Government states plainly: "Private landlords have a duty to carry out a risk assessment of hot and cold water systems for legionnaire's disease to minimise the risk of tenants being exposed to legionella." You do not need a certificate, and most landlords can carry out a simple assessment themselves.

What is the same as the rest of the UK

The underlying control measures are identical, because the science and the core HSE guidance (ACoP L8 and HSG274) apply across Great Britain:

• Hot water stored at 60°C, delivered at 50°C at outlets
• Cold water kept below 20°C
• Flushing of infrequently used outlets
• Cleaning and descaling of showerheads
• No "legionella certificate" required — what you need are records

For the building-level mechanics, our landlord legionella guide and risk assessment review frequency guide apply equally in Scotland.

What is specifically different in Scotland

1. The duty runs through the Repairing Standard

In Scotland, private rented property must meet the Repairing Standard. The statutory guidance for private landlords explicitly folds the legionella risk assessment into that framework, which means it is not just a health-and-safety expectation — it is part of the standard your property must meet to be legally let. A failure here can be raised with the First-tier Tribunal for Scotland (Housing and Property Chamber), the body that handles Repairing Standard disputes.

2. A stated two-year review interval

This is the clearest practical difference. HSE guidance for England and Wales is risk-based — it does not prescribe a fixed review interval. The Scottish Government's guidance does: it asks landlords to assess "before the property is first let" and to review the assessment "at intervals of no more than two years." If you let in Scotland, treat two years as your maximum review cycle rather than a soft industry norm.

3. A pre-let flush requirement

The Scottish guidance includes a specific control measure that is easy to miss: "Flush out the system prior to letting the property, if this has not been done within the previous two years." If a property has stood empty between tenancies, or you are letting it for the first time in a while, flush the system before the new tenant moves in.

4. Specific tenant advice

The guidance also lists what tenants should be told: not to adjust the hot water tank's temperature setting, and to regularly clean and disinfect showerheads. Putting this in writing at the start of a tenancy is part of demonstrating you have managed the risk.

A simple compliance checklist for Scottish landlords

1. Assess before first let — carry out a legionella risk assessment of the hot and cold water system.
2. Flush before letting — if the system has not been flushed in the last two years, flush it before the tenant moves in.
3. Set storage to 60°C — ensure the hot water tank stores at least 60°C; advise the tenant not to change it.
4. Brief the tenant — give written advice on not adjusting the tank and on cleaning showerheads.
5. Review every two years (maximum) — and sooner if the system or building use changes.
6. Keep records — the assessment, control measures, and any temperature checks. These are your evidence if the tenancy is ever disputed.

You can generate a building-type-specific assessment document with our free Risk Assessment Template Generator, then keep your temperature and flushing records alongside it.

Where to verify

The definitive Scottish source is the Repairing Standard statutory guidance for private landlords. Tenant-facing guidance is summarised on mygov.scot, which confirms: "You must assess your property for health risks associated with legionella." For the underlying control methods, HSE's guidance applies across Great Britain.

This guidance covers legionella duties for private landlords in Scotland under the Repairing Standard and UK-wide health and safety law. This is general compliance guidance, not legal or professional advice — for site-specific assessments, consult a competent person, and verify Repairing Standard obligations against the current Scottish Government guidance.
