Lambeth charges up to £1,412 for a five-year HMO licence — and landlords who skip the process face civil penalties that can exceed that figure many times over.
What Triggers HMO Licensing in Lambeth?
Mandatory HMO licensing applies to any property occupied by 5 or more people forming 2 or more separate households, where occupants share facilities such as a kitchen or bathroom. This is the national threshold set under the Housing Act 2004, and Lambeth enforces it fully. However, Lambeth also operates an Additional Licensing scheme covering smaller HMOs with 3 or more occupants forming 2 or more households across the entire borough. This means a landlord with a modest three-person house share in Streatham, Brixton, or Clapham needs a licence just as much as the owner of a larger property. The Additional Licensing designation is a formal decision made under Section 56 of the Housing Act 2004, and Lambeth has renewed such schemes to maintain borough-wide coverage. If your property has 3 or more occupants from separate households sharing amenities, the licensing requirement is triggered regardless of the number of storeys.
What Does an HMO Licence Cost in Lambeth?
Lambeth structures its fees in two parts: a non-refundable application fee paid upfront, and a licence issue fee paid on approval. For a mandatory HMO licence, the total five-year fee is £1,412. For an additional licence (covering 3–4 occupant properties), the fee is £1,154 for the five-year term. Landlords who are members of an approved accreditation scheme — such as the National Residential Landlords Association (NRLA) or the London Landlord Accreditation Scheme (LLAS) — may be eligible for a discounted rate, typically around £100 to £150 off the total fee depending on the current scheme conditions. Fees are non-refundable once the application has been processed, so ensuring your property meets the required standards before applying is strongly advisable. Licences run for a maximum of 5 years, after which a full renewal application and fee are required.
How Do You Apply for an HMO Licence in Lambeth?
Applications are submitted through Lambeth Council's online licensing portal. Before applying, landlords must ensure the property meets the Lambeth HMO licensing standards, which include minimum room sizes — a single bedroom occupied by one adult must be at least 6.51 square metres, and a room used by two adults must be at least 10.22 square metres. These are national minimums under the Licensing of Houses in Multiple Occupation (Mandatory Conditions of Licences) (England) Regulations 2018, and Lambeth applies them in full. The application itself requires details of the licence holder, the proposed licence conditions, details of any managing agent, and confirmation that the property is fit for the stated number of occupants. A fit and proper person assessment is carried out on the applicant; any unspent convictions relating to fraud, violence, or housing offences will be taken into account and can result in refusal.
What Documents Do You Need?
Lambeth requires a specific set of supporting documentation to accompany every HMO licence application. You will need a current gas safety certificate (valid within 12 months), an Electrical Installation Condition Report (EICR) dated within the last 5 years, energy performance certificate (EPC) with a minimum rating of E, fire safety risk assessment, and evidence of working smoke and heat alarms on every floor. A floor plan of the property showing room dimensions is required to verify room size compliance. If the property has an HMO manager other than the owner, a copy of the management agreement must be included. Missing or expired documentation is one of the most common reasons Lambeth returns applications as incomplete, adding weeks to processing time.
What Happens If You Don't Have a Licence?
Operating an unlicensed HMO in Lambeth is a criminal offence under Section 72 of the Housing Act 2004. Lambeth Council can issue a civil penalty of up to £30,000 per offence as an alternative to prosecution. Where a landlord is prosecuted through the criminal courts, an unlimited fine can be imposed. Beyond direct penalties, tenants in an unlicensed HMO are entitled to apply for a Rent Repayment Order (RRO) through the First-tier Tribunal, potentially reclaiming up to 12 months of rent paid during the unlicensed period. A landlord who receives an RRO or civil penalty may also be added to the Rogue Landlord Database, which can affect the ability to obtain future licences. Lambeth's private sector housing enforcement team actively investigates unlicensed properties, including acting on complaints from tenants and referrals from other council departments.
What This Means for Lambeth HMO Landlords
The combination of mandatory and additional licensing means that virtually every shared house in Lambeth with 3 or more unrelated occupants requires a licence. With a five-year licence costing up to £1,412 — equivalent to roughly £282 per year — the fee itself is manageable within normal operating costs. The real financial risk lies not in the licence fee but in the penalties for non-compliance: a single £30,000 civil penalty dwarfs the cost of any licence. Landlords who acquired Lambeth properties as part of portfolio growth in areas such as Brixton, Norbury, or West Norwood should audit their current tenancy structures against the 3-person threshold immediately. Any change in occupancy — a new housemate moving in, for example — can push a property into licensing territory with immediate effect. Lambeth does not offer a grace period once the threshold is met; the obligation to hold a valid licence arises on the day the threshold is crossed.
