HMO Licensing Croydon: Mandatory Licence Fees, Thresholds and Penalties Explained

The trigger for mandatory licensing is straightforward: your property must be licensed if it is occupied by 5 or more people from 2 or more separate households, and it shares facilities such as a kitchen or bathroom. This is the national standard threshold set by the Housing Act 2004, and Croydon applies it in full. Properties of any storey count now fall within mandatory licensing following the October 2018 extension of the national scheme, which removed the previous 3-storey threshold that once allowed many smaller HMOs to operate without a licence. If your property was previously exempt on storey grounds, it has required a licence since 1 October 2018.

Beyond mandatory licensing, landlords should be aware that Croydon also operates selective licensing in designated wards. In those areas, even standard single-tenancy properties require a licence, so it is worth checking the council's interactive map if your property sits in Thornton Heath, Broad Green, or other historically designated zones. Selective licence fees differ from HMO fees, so confirm which scheme applies before calculating your costs.

What does an HMO licence cost in Croydon?

Croydon Council charges a 5-year mandatory HMO licence fee structured in two stages. The non-refundable application processing fee is £702, paid at the point of submission. A further £702 is due on grant of the licence, bringing the total to £1,404 for a standard 5-year licence. This fee covers properties with the standard occupancy profile; additional rooms or occupants may attract supplementary charges, so confirm the current fee schedule directly with Croydon's Private Sector Housing team before submitting.

For landlords who are accredited through a recognised scheme such as the National Residential Landlords Association (NRLA) or the London Landlord Accreditation Scheme (LLAS), some London councils offer a reduction — typically 10% to 15% — though Croydon's discount position should be confirmed at the point of application as the council periodically revises its fee policy. Over the 5-year licence term, the annual cost equates to approximately £281, making early and proactive licensing the most cost-effective approach.

How do you apply for an HMO licence in Croydon?

Applications are submitted through Croydon Council's online licensing portal. The process requires you to create an account, select the correct licence type (mandatory HMO), complete the property and management declarations, and upload your supporting documents. Most applicants complete the online form in under 2 hours if documents are prepared in advance.

The council targets a processing time of 12 to 16 weeks for complete applications, though this can extend during high-volume periods. A licence is typically granted for 5 years, though Croydon reserves the right to issue a shorter licence — sometimes as brief as 1 year — where there are concerns about management standards or where the property needs remedial works. Licences are non-transferable: if the property is sold or management responsibility changes, a new application is required within 28 days of the change.

What documents do you need to submit?

A complete application requires a specific set of documents. You will need a current gas safety certificate (valid within the last 12 months), an electrical installation condition report (EICR) dated within the last 5 years, energy performance certificate (EPC), fire alarm test certificate, emergency lighting test certificate where applicable, and a floor plan of the property showing room dimensions, usage, and the location of fire detection equipment. You must also provide proof of ownership or authority to act, and evidence of the current tenancy or intended occupancy arrangement.

Planning permission documentation may be required if the property has changed use from C3 (single dwelling) to C4 (small HMO) or Sui Generis (large HMO). In Croydon, properties accommodating 7 or more unrelated occupants are classified as Sui Generis and require full planning permission regardless of licensing status — these are separate legal obligations.

What are the penalties for operating without a licence?

This is where Croydon takes an unambiguous position. Operating an unlicensed HMO is a criminal offence under Section 72 of the Housing Act 2004, carrying an unlimited fine on prosecution. Croydon Council also uses the civil penalty route, issuing notices of up to £30,000 per offence. In cases involving serious management failures, the council can prosecute under the Housing and Planning Act 2016, which introduced civil penalties as an alternative to criminal prosecution.

Beyond fines, an unlicensed landlord faces a rent repayment order (RRO): tenants and the council can each apply to the First-tier Tribunal (Property Chamber) to recover up to 12 months' rent paid during the unlicensed period. For a 5-room HMO in Croydon where each tenant pays £700 per month, a 12-month RRO exposure across all occupants could reach £42,000 — far exceeding the cost of a £1,404 licence.

The council can also issue an interim or final management order, taking over management of the property for up to 5 years, during which rental income is directed to the council rather than the landlord.

What does this mean for Croydon landlords right now?

If you own an HMO in Croydon that meets the 5-person, 2-household threshold and do not hold a current licence, apply immediately. The cost of delay is disproportionately high relative to the £1,404 licence fee. If you are considering purchasing an HMO in Croydon, verify whether an existing licence is in place and whether it is transferable — it is not, so factor a fresh application into your timeline and budget. With council processing times of up to 16 weeks, plan your application at least 4 months ahead of the intended occupation date to avoid operating in breach.
