HMO Licensing Wandsworth: Mandatory Scheme, Fees and the £30,000 Penalty Landlords Must Know

The mandatory national HMO licensing scheme applies to any property occupied by 5 or more persons forming 2 or more separate households, where residents share facilities such as a kitchen or bathroom. This threshold has been in place since October 2018, when the government removed the previous 3-storey requirement, significantly widening the net for landlords across England — including Wandsworth. If your property houses a family of 5 or more alongside a single unrelated occupant, it falls outside the definition; the 2-household rule is as important as the headcount. Wandsworth does not currently operate an additional licensing scheme covering smaller HMOs, so properties with 3 or 4 occupants forming 2 or more households do not currently require a licence — but that position can change with 10 weeks' notice from the council.

Beyond the mandatory scheme, landlords should check whether a selective licensing designation applies to the specific street or ward their property sits in. Wandsworth has used selective licensing in targeted areas and can reactivate or extend such schemes. Any selective licence is a separate obligation and carries its own fee, typically in the range of £500 to £750 for a 5-year term.

How much does an HMO licence in Wandsworth cost?

The standard 5-year mandatory HMO licence fee in Wandsworth is £1,411, payable to the London Borough of Wandsworth. This breaks down into two stages: a non-refundable application processing fee paid upfront, and a second instalment due on grant of the licence. Landlords should budget for both elements from the outset, as the first payment is forfeited even if the application is ultimately refused.

Accredited landlords — those registered with the London Landlord Accreditation Scheme (LLAS) or a recognised equivalent — may qualify for a reduced fee. The discount is typically around 10%, bringing the total closer to £1,270, though landlords should confirm the current figure directly with the council's private sector housing team before applying, as fee schedules are reviewed periodically.

Licence fees are not transferable. If you sell the property, the new owner must apply for their own licence. If you purchase a licensed HMO, do not assume the existing licence protects you from enforcement — it almost certainly does not cover you as the incoming licence holder.

How do you apply for an HMO licence in Wandsworth?

Applications are submitted online through Wandsworth Council's licensing portal. The process requires you to have all supporting documentation ready before you begin, as the system does not readily allow partial saves without risk of losing progress. Allow at least 2 to 3 hours to complete a thorough submission for a straightforward property.

The council aims to determine applications within 8 weeks of receiving a complete, valid submission. If significant works are required to bring the property up to standard, the council may issue an interim licence for up to 12 months while those works are carried out, with the full 5-year licence following on satisfactory completion.

What documents do you need to apply?

A complete Wandsworth HMO licence application requires the following: a current gas safety certificate (valid for 12 months), an electrical installation condition report (EICR) dated within the last 5 years, energy performance certificate (EPC) — currently required to show a minimum E rating, though the government's target to raise this to C by 2030 remains policy direction — fire alarm system commissioning certificate, emergency lighting certificate where applicable, and a floor plan drawn to scale showing room dimensions and square metreage for each letting room.

Each letting room must meet the national minimum size standards: 6.51 square metres for a single adult, 10.22 square metres for two adults. Wandsworth officers apply these thresholds strictly during inspections. Rooms falling below these sizes must not be let, even if they were previously occupied without complaint.

Proof of ownership or management authority, a fit and proper person declaration, and details of any managing agent must also be submitted. If you have previous convictions relating to housing, fraud or violence within the last 5 years, these must be declared — non-disclosure is treated as a serious aggravating factor in any subsequent enforcement.

What happens if you operate without a licence in Wandsworth?

This is where the consequences become severe. Wandsworth Council has the power to issue a civil penalty notice of up to £30,000 per unlicensed property. This is not a theoretical maximum — councils across London have issued penalties at or near this level. On top of the civil penalty route, the council retains the right to pursue criminal prosecution, which carries an unlimited fine on conviction in the magistrates' court.

A rent repayment order (RRO) compounds the financial exposure significantly. Tenants — or the local authority — can apply to the First-tier Tribunal (Property Chamber) for repayment of up to 12 months' rent where the property was unlicensed. On a property generating £2,500 per month in rent, that represents a potential £30,000 exposure from tenants alone, entirely separate from the council penalty.

Landlords found to have knowingly operated without a licence are also placed on the database of rogue landlords, a record that carries serious implications for future licence applications, local authority tenancy agreements, and, from 2026, interactions with the proposed Renters' Rights Act landlord registration scheme.

What this means for Wandsworth landlords right now

If you own a property in Wandsworth occupied by 5 or more people across 2 or more households, you must hold a valid licence today. If you are purchasing such a property, factor the £1,411 licensing fee into your completion timeline and begin the application within 7 days of completion. If your property has 3 or 4 occupants, monitor the council's website for any additional licensing consultation — the 10-week notice period moves quickly, and retrospective compliance is far costlier than proactive preparation.
