From Kensington to Hounslow, West London’s property market moves fast, and councils are moving faster on compliance. If you rent out a flat in Hammersmith, run a care home in Ealing, or manage a hotel near Heathrow, you need a legionella risk assessment that holds up when the licensing officer knocks.
At Landlord Certification. We have been doing this since 2014, our assessors are City and Guilds certified, DBS checked, and based in West London. We know the difference between a mansion block in Fulham with a communal tank from the 1970s and a new building in Brentford with a pressurised system. That knowledge matters because the risks are different, the fixes are different, and the council expectations are different.
We do not send someone from Croydon who has never seen a soft water zone. We send someone who knows why Richmond’s limescale patterns differ from Hounslow’s, who understands Thames Water pressure drops in conservation areas, and who can assess a premium Kensington let without leaving scuff marks on the parquet.
A legionella risk assessment is a systematic inspection of your water systems to identify where Legionella bacteria could grow and cause Legionnaires’ disease. It is not a visual glance and a tick box. It is a documented evaluation that courts and councils treat as evidence of your duty of care.
In West London, the context matters. A period property in Kensington with original lead pipework and a gravity-fed tank in the loft carries different risks from a purpose-built flat in Ealing with a combi boiler and no storage. A mansion block in Hammersmith with a communal cylinder serving twelve flats needs assessing as a system, not twelve separate taps. A Heathrow-area hotel with rooms empty one night and full the next faces stagnation risks that a family home does not.
Our assessment covers:
Existing control measure review, is someone actually checking temperatures monthly?
Every landlord in West London must assess Legionella risk. Not just HMO landlords or commercial landlords. Every landlord lets a residential property under the Health and Safety at Work etc. Act 1974 and COSHH 2002. The reality on the ground:
Tenants paying premium rates expect premium service. Their letting agent will ask for your assessment before the tenancy agreement is signed. Landlord Certification provides discreet, unmarked-vehicle service and reports formatted for agent submission.
Councils here are active. Ealing’s selective licensing scheme and Hounslow’s additional licensing scheme both include property condition checks. A missing or inadequate legionella risk assessment is an easy mark against you.
High turnover, intermittent occupancy, and complex plumbing create perfect conditions for stagnation. We assess these as commercial systems, not domestic lets.
Shared kitchens, irregular shower use during holidays, and rapid tenant changeover need a proactive approach, not a reactive one.
The penalties are real. Fines up to £20,000. Prosecution in severe cases. Invalid insurance that leaves you exposed to civil claims. License refusal that stops you letting out entirely.
Employers have the same legal duty. The difference is scale and complexity.
Multi-tank systems, TMVs, cooling infrastructure, and 24-hour occupancy. One missed temperature check can affect hundreds of guests.
Conversions of Victorian industrial buildings with original pipework hidden behind new plasterboard. Out of sight, not out of risk.
Back-of-house water systems for staff kitchens and toilets that see heavy use but little maintenance attention.
Large footprint, low occupancy, and long pipe runs that create dead legs by design.
Healthcare premises with higher regulatory scrutiny and patient vulnerability.
Shower blocks with high throughput and intermittent temperature control.
You call or email Landlord Certification. We ask about your property type, borough, and any known issues. A local assessor reviews your details — not a call centre reading from a script.
We factor in borough-specific requirements from the outset:
You receive a fixed-price quote with no obligation. Discreet service for premium properties is standard, not extra.

For high-end letting agents and commercial clients, Landlord Certification formats reports for direct portal upload. For landlords, every finding is explained in plain English.
Every Landlord Certification assessment includes a free 30-minute follow-up call. We explain what we found, what you must do, and what you should monitor going forward.
If remedial work is needed — tank replacement, TMV servicing, pipework modification — we recommend trusted local contractors we have worked with before.
We also provide an annual reminder service. Legionella risk assessments must be reviewed every two years minimum, or sooner if your system changes, new tenants move in, or after any plumbing work.
Landlord Certification believes in transparent, fair pricing for every West London property. The cost of your legionella risk assessment depends on property type, system complexity, and the number of water outlets. A single flat in Ealing with a combi boiler requires less survey time than a multi-tank commercial system in a Heathrow hotel. Domestic properties typically cover all hot and cold outlets, storage vessels, and temperature checks. Commercial assessments are priced according to system size and complexity. Landlord Certification offers fixed quotes with no surprise charges, and portfolio discounts for letting agents and multi-property landlords across West London. Every quote includes the full on-site survey, photographic evidence, detailed written report, and free follow-up consultation. Travel costs within West London are included. There are no hidden fees.

In 2026, West London councils are actively enforcing Legionella compliance as part of selective and additional licensing schemes. Hammersmith and Fulham licensing officers now routinely request valid legionella risk assessments during property inspections and license renewals. Ealing’s selective licensing scheme includes water safety checks. Kensington and Chelsea’s environmental health team has issued improvement notices for inadequate Legionella control.
The legislation is clear:
We’re trusted by businesses and property owners across London for reliable,
compliant safety services delivered with professionalism and care.
Costs vary by property type and system complexity. Landlord Certification provides transparent, fixed quotes with no hidden charges. Single residential properties start at an accessible range, while commercial premises are priced according to survey time and report detail.

Yes, all landlords must assess Legionella risk under the Health and Safety at Work Act 1974 and COSHH 2002. West London councils increasingly check during licensing inspections, particularly in Ealing, Hounslow, and Hammersmith and Fulham. Without a valid assessment, you risk fines, licence refusal, and invalid insurance. Landlord Certification provides documented compliance.
Kensington and Chelsea, Hammersmith and Fulham, Ealing, Hounslow, Brent, Hillingdon, Richmond upon Thames, Kingston upon Thames, plus surrounding areas. Travel costs within West London are included.
Every two years as a minimum. Sooner if your system changes, new tenants move in, or after any plumbing work. Landlord Certification provides annual reminder service so you do not miss deadlines.
A legionella risk assessment identifies conditions where bacteria could grow. It is a physical inspection and evaluation. Legionella testing involves laboratory analysis of water samples to detect actual bacteria. Testing is only required if your assessment indicates a specific need, such as after a system failure or during an outbreak investigation.
Same-week appointments are usually available. Most domestic assessments take 45 to 90 minutes on site. Reports are delivered within 24 to 48 hours. For urgent licensing deadlines or tenancy start dates, Landlord Certification prioritises accordingly.
