Legionella Risk Assessment in Brent: local enforcement context
London Borough of Brent operates Additional HMO licensing at £1,040, with a current Legionella risk assessment for any property with a stored or distributed water system required as a licence-grant condition under HSE Approved Code of Practice L8 (ACOP L8) and HSG274. Brent Council operates a borough-wide Additional HMO licensing scheme that has been live since 2 February 2026, bringing every 3-4 occupant HMO across the borough into licensing. From 1 May 2026, the Renters' Rights Act raises the civil-penalty cap from £30,000 to £40,000 per breach and gives tenants the ability to claim Rent Repayment Orders covering up to 24 months of rent from non-compliant landlords. The licensing team treats fire risk assessments, EICRs and compartmentation in converted terraces as routine licence-grant checks, so landlords in NW10, NW6 and HA9 should have current documentation in place before applying.
Brent's housing stock is dominated by Victorian and Edwardian terrace conversions in Harlesden (NW10) and Kilburn (NW6), post-war and inter-war stock around Wembley (HA9), and period housing in Willesden and Cricklewood. The borough has one of the highest HMO concentrations in north-west London, with much of the private rented stock split into shared accommodation or self-contained conversions above the NW10 and NW6 high streets.

Legal Requirements for Legionella Risk Assessment
Relevant Legislation
HSE Approved Code of Practice L8 (ACOP L8) and HSG274
The Health and Safety Executive's Approved Code of Practice L8 (Legionnaires' disease: The control of Legionella bacteria in water systems) and its associated guidance documents HSG274 Parts 1–3 set out the legal duty to assess and control Legionella risk in any water system that could create a foreseeable risk of exposure. Landlords have an explicit duty under the Health and Safety at Work etc. Act 1974 and the associated COSHH Regulations 2002 to assess the risk of Legionella to tenants from hot and cold water systems.
Who Needs This?
Landlords (both residential and commercial), employers, building managers, and anyone who has maintenance or repair obligations for water systems. The HSE has confirmed that landlords of domestic rental properties are 'duty holders' and must assess the risk from Legionella in their properties. Care homes, schools, hotels, and any premises with water systems that store or distribute water are also in scope.

Frequently Asked Questions
What conditions cause Legionella bacteria to grow?+
Legionella bacteria thrive in water temperatures between 20°C and 45°C, in stagnant water, and where there is biofilm, rust, scale, or sediment providing nutrients. Systems most at risk include those with dead legs (unused pipe runs), infrequently used outlets, storage tanks without lids, and water systems where the hot water is not stored at 60°C or above. The assessment identifies these risk factors in your specific property.
How often should a Legionella risk assessment be reviewed?+
There is no fixed legal frequency, but the HSE recommends reviewing the assessment at least every two years, or sooner if there is a change to the water system, the building use changes, the results of monitoring suggest problems, or a case of Legionnaires' disease is linked to the building. For higher-risk buildings such as care homes and hotels, annual reviews are standard practice.
What does the assessor check during a Legionella risk assessment?+
The assessor examines all hot and cold water systems, including boilers, cylinders, storage tanks, calorifiers, showers, taps, and any associated pipework. They check water temperatures at sentinel outlets (nearest and furthest from the heat source), look for dead legs or rarely used outlets, inspect tank lids and insulation, review the system schematic, and assess whether current controls are adequate to prevent bacterial growth.
Do I need a Legionella risk assessment to apply for a Brent property licence?+
London Borough of Brent operates Additional HMO (£1,040). A current Legionella risk assessment for any property with a stored or distributed water system is a licence-grant condition — the team checks the document at application and will return incomplete submissions.
Which parts of Brent most often need a Legionella risk assessment?+
In Brent, the highest demand for Legionella risk assessment comes from NW10 (Harlesden), HA9 (Wembley), NW6 (Kilburn) — areas with the largest concentration of Victorian and Edwardian terrace conversions in Harlesden and Kilburn and post-war and inter-war Wembley housing. Victorian and Edwardian terrace conversions in Harlesden and Kilburn and post-war and inter-war Wembley housing commonly have stored hot water systems and dead-leg pipe runs that need recording in the risk assessment.
