South London landlords have a particular problem. Everyone talks about the north and east the regeneration headlines, the Olympic money, the tech boom. But down here, the work is harder and the scrutiny is sharper. Lambeth’s licensing team will refuse your application over a missing water safety document. Wandsworth’s new scheme carries £30,000 penalties. Lewisham runs two separate licensing regimes simultaneously. And through it all, you’re managing Victorian plumbing in Brixton, 1960s communal systems in Peckham, and new-build pressure cylinders in Battersea that the developer’s manual got wrong.
We are Landlord Certification, since 2014 we have assessed properties across every South London borough. Our engineers are City and Guilds certified and DBS checked. They know that a terrace in Streatham with three conversions and a loft extension has different risks from a purpose-built flat in Croydon. They know that Thames Water’s South London infrastructure programme, £330 million of mains replacement and pumping station upgrades, is changing pressure dynamics street by street, and that this affects how your cylinder performs.
More importantly, they know how to get your report accepted by Lambeth’s portal first time, how to format for Wandsworth’s phased licensing rollout, and how to satisfy Lewisham’s dual inspection regime without you having to resubmit twice.
A legionella risk assessment is not a clipboard walk-through. It is a systematic, documented inspection of your water systems that identifies where Legionella bacteria could multiply. The law requires it under the Health and Safety at Work etc. Act 1974 and COSHH 2002. The standard is HSE ACoP L8 and HSG 274. If a tenant contracts Legionnaires’ disease and you cannot produce a valid assessment, you face fines up to £20,000, prosecution, and personal liability that your insurance may not cover. South London’s specific risks come from its housing diversity:
Original gravity-fed tanks, lead pipework, and multiple extensions that created dead legs when kitchens and bathrooms were moved. Often converted to HMOs with shared facilities and rapid tenant turnover that accelerates stagnation.
Communal cylinders serving multiple flats, intermittent hot water, and replacement programmes that have not reached every block. Leaseholders frequently discover they are the responsible landlord only when the council writes to them.
Shared systems with unclear responsibility splits between freeholders, managing agents, and leaseholders. Wandsworth’s selective licensing scheme now covers these wards specifically, adding another layer of compliance pressure.
Pressurised systems with commissioning gaps, long pipe runs to upper floors, and TMVs that were installed but never properly balanced. The marketing materials promised luxury living. The plumbing often needs remedial work to match.
Family homes with combi boilers that seem straightforward until you find the garden office with its own supply, the granny flat extension, or the loft conversion with an uninsulated tank that freezes in winter and overheats in summer.
Hotels, restaurants, and offices with complex systems, high footfall, and employer duties that run parallel to but separate from any landlord obligations.
South London councils have been more aggressive than most in linking property licensing to water safety compliance. This is not theoretical, we see the refusal letters and the improvement notices.
Selective licensing rolled out in two phases: September 2024 for four wards, September 2025 for nineteen more. Only Vauxhall and Waterloo & South Bank are exempt. The fee is £923. Discounts apply for accredited landlords and properties with EPC ratings of C or above. Water safety is a mandatory inspection point. We format our reports for direct portal upload.
Selective licensing launched July 2025 in Furzedown, Tooting Bec, Tooting Broadway, and South Balham. Expands April 2026 to East Putney, West Putney, and Northcote. The fee is approximately £850. Penalties for non-compliance reach £30,000. We have already seen landlords caught out who assumed their ward was not yet covered.
Selective licensing covers 18 wards with a £640 fee, split into two payments. Additional HMO licensing applies borough-wide for properties with three or more sharers, introduced April 2022. Water safety checks are embedded in both regimes.
Selective licensing operates across the borough with increasing enforcement focus on HMOs and ex-council properties. Water safety documentation is now routinely requested during inspections.
No borough-wide selective licensing currently, but the legal duty to assess Legionella risk remains absolute. We assess affordably for landlords who want to stay ahead of any future scheme.
This is the environment you operate in. Landlord Certification navigates it with you.
You call or email. We ask about your property, your borough, and any deadlines you are facing. A local assessor reviews your situation, not a call centre operative. We factor in Lambeth’s portal requirements, Wandsworth’s phased rollout, Lewisham’s dual regime, and Southwark’s enforcement priorities. You receive a fixed-price quote with no obligation.
Our engineer arrives on time, with ID and DBS clearance. They are City and Guilds certified and have assessed hundreds of South London properties. They understand Victorian plumbing behind period features, communal systems in mansion blocks, pressure variations from Thames Water’s infrastructure works, and access protocols for tower blocks and commercial premises. The survey takes 45 to 90 minutes for a typical domestic property. Commercial premises vary.
Within 24 to 48 hours you receive a professional document: executive summary, detailed findings with photographs, prioritised action plan, temperature log, schematic diagram, and compliance certificate. For Lambeth and Wandsworth licensing applications, we format for direct portal upload. For individual landlords, we explain every finding in plain English.
Every legionella risk assessment service includes a free 30-minute call to explain findings and next steps. If remedial work is needed, we recommend trusted local contractors. No referral fees. We also provide annual reminder service so you never miss a reassessment deadline.
Transparent, fixed pricing with no hidden charges. Your legionella risk assessment cost South London depends on property type, system complexity, and the number of outlets we check. A one-bed flat in Croydon with a combi boiler is quicker to assess than a multi-tank hotel near Waterloo or a mansion block in Clapham with communal systems. Domestic assessments cover all outlets, storage vessels, and temperature checks. Commercial assessments scale with system size and complexity. Portfolio discounts available for letting agents and landlords with multiple South London properties. Every quote includes the full survey, photographic evidence, written report, and follow-up call. Travel within our South London coverage area is included.

South London councils are actively enforcing Legionella compliance through their licensing schemes. Lambeth’s selective licensing, now covering virtually the entire borough, includes mandatory water safety documentation. Wandsworth’s expanding scheme carries penalties up to £30,000. Lewisham’s dual licensing regime embeds water safety checks in both selective and additional HMO schemes. Southwark’s enforcement team has increased activity on HMO water safety.
The legislation:
Penalties reach £20,000. Prosecution follows serious failures. Licence refusal stops you letting. Invalid insurance leaves you exposed.
We’re trusted by businesses and property owners across London for reliable,
compliant safety services delivered with professionalism and care.
The legionella risk assessment cost South London property owners pay depends on property type and system complexity. A standard domestic assessment for a flat or house typically falls within an accessible fixed range. Commercial premises with larger systems cost more due to survey time and report detail. Landlord Certification provides transparent, no-obligation quotes before any work begins. Portfolio discounts are available for multi-property landlords.
Yes. All landlords in South London must assess Legionella risk in their rental properties under the Health and Safety at Work etc. Act 1974 and COSHH 2002. Lambeth, Wandsworth, and Lewisham are particularly active in checking this during licensing inspections. Without a valid assessment, you risk fines, licence refusal, and invalid insurance. Landlord Certification provides the documented compliance you need.
We cover Lambeth, Southwark, Lewisham, Wandsworth, Croydon, Bromley, and Bexley. Travel costs within South London are included. We also serve surrounding areas by arrangement.
Every two years as a minimum. You must also review your assessment if there are changes to the water system, 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 that could allow bacteria to grow. It is a physical inspection and evaluation of your water system. 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. Landlord Certification advises when testing is necessary and arranges it if required.
Same-week appointments are usually available. Most domestic assessments take 45 to 90 minutes on site. Landlord Certification delivers reports within 24 to 48 hours. For urgent licensing deadlines or tenancy start dates, we prioritise accordingly.
Yes. We regularly assess new developments in Battersea, Nine Elms, and other regeneration areas where communal systems, unclear responsibility splits, and commissioning gaps create specific risks. We clarify duty and provide assessments that satisfy managing agents and freeholders.
There is no pass or fail. The assessment identifies risks and rates them by urgency. Landlord Certification provides a prioritised action plan. We explain what you must do immediately, what can wait, and what to monitor. For urgent remedial work, we recommend trusted local contractors. For minor issues, we guide you through simple fixes yourself.
