HMO Licence Conditions Explained: What You're Actually Signing Up To

Getting your HMO licence granted isn't the end of the obligations — it's the start of a defined set of conditions you're legally required to keep meeting for the life of the licence. Under the Licensing of Houses in Multiple Occupation (Mandatory Conditions of Licences) (England) Regulations 2018, certain conditions are attached to every mandatory HMO licence in England, and councils can add further conditions on top of them. Understanding what you actually signed up to — not just the headline fact that you hold a licence — is what keeps you compliant between renewals, not just at the point of application.

Gas safety

A valid, up-to-date gas safety certificate must be in place at all times, renewed annually, and a copy provided to the council on request. This isn't a one-off check tied to the licence application — it's a rolling annual obligation that continues for as long as the property has any gas appliances, regardless of where you are in the licence term. Landlords sometimes let the renewal date drift because the certificate isn't due to expire until months after the licence was granted, then find themselves relying on an expired certificate when a council inspection or a tenant complaint brings an inspector to the door.

Keep the certificate somewhere your managing agent or letting team can access quickly, since a written request from the council doesn't come with a long lead time to produce it.

Electrical safety

Electrical installations must be inspected and tested at intervals not exceeding five years by a qualified person, with a satisfactory report supplied to the council within 7 days of a written request. The five-year interval is a maximum, not a target — if a previous report flagged remedial work or noted a shorter recommended re-test period, that shorter interval takes precedence. An EICR that comes back unsatisfactory, or that lists work as required rather than merely recommended, needs the remedial work carried out and a follow-up report obtained before the condition can be treated as met.

This is one of the few conditions where a specialist trade matters more than general property maintenance — the person carrying out the inspection needs to be appropriately qualified, and electrician247.london is one option if you need a NICEIC-certified inspection and certificate for a London property.

Smoke alarms and carbon monoxide

Smoke alarms must be installed and kept in proper working order on each storey used as living accommodation, and carbon monoxide alarms must be fitted in any room used as living accommodation containing a solid fuel-burning appliance. Kept in proper working order is doing real work in that condition — a smoke alarm installed and tested at the point of licensing but since disconnected by a tenant who found it too sensitive no longer satisfies the requirement, and the licence holder remains responsible for it regardless of who caused the fault.

In practice this means a periodic testing routine, not a single installation event. Many licence holders build alarm checks into routine property visits or tenancy changeovers so a fault doesn't sit undetected for months.

Furniture safety

Any furniture supplied by the landlord must meet fire safety standards under the Furniture and Furnishings (Fire) (Safety) Regulations. This applies to every piece of furniture the landlord provides as part of the letting, not just items bought new for the purpose — inherited furniture from a previous letting, or items acquired secondhand, need the same compliant fire labelling as anything bought specifically for the HMO. Furniture without a permanent label confirming compliance is generally treated as non-compliant, so keep labels intact rather than removing them for appearance.

Room size minimums

Mandatory conditions set minimum room sizes for sleeping accommodation: at least 6.51 square metres for one person over 10 years old, 10.22 square metres for two people over 10, and 4.64 square metres for a child under 10. Rooms below 4.64 square metres cannot be used as sleeping accommodation at all, regardless of how the household wants to allocate space. These figures apply to floor area actually usable for the purpose, and councils measuring a room for compliance will typically exclude areas with substantially reduced headroom, so a converted loft space with a lot of sloped ceiling can measure larger on paper than it does in practical usable terms.

Getting room sizes wrong is one of the more common reasons a licence application stalls, because it usually only surfaces once a council officer visits and measures the property rather than at the point of submission.

Waste management

The licence holder must comply with the council's scheme for the storage and disposal of household waste pending collection. Every borough runs its own scheme, and what counts as compliant storage in one area — communal bins, a specific enclosure, bagged waste left out on a set day — can be entirely different in the next borough. For an HMO with multiple households generating waste independently of one another, this condition is also one of the more visible ones to neighbours and enforcement officers, since overflowing bins or waste left out on the wrong day are easy to spot without ever entering the property.

Conditions can go further than the minimum

Councils can, and often do, attach additional conditions beyond the mandatory list above — particularly for additional and selective licences, where local schemes set their own supplementary requirements. These can include limits on the number of persons per room beyond the statutory minimums, requirements for a written tenancy management plan, restrictions on letting to certain household compositions, or additional fire precautions specific to the property's layout. Always check your specific licence document rather than assuming only the mandatory conditions above apply, because the conditions notice that comes with your licence is the actual legal instrument — the general regulations are a floor, not the full picture.

What happens if you breach a condition

Breaching a licence condition is an offence in its own right, separate from operating entirely without a licence. Councils can issue civil penalties of up to £30,000 per offence, and from 1 May 2026 the Renters' Rights Act 2025 introduces a tiered structure — up to £7,000 for minor or initial non-compliance, rising to up to £40,000 for serious, persistent or repeat non-compliance. A tenant can also apply to the First-tier Tribunal for a rent repayment order in some circumstances connected to licensing failures, so a condition breach is rarely just a paperwork issue — it carries real financial exposure, and a pattern of breaches can also affect the fit and proper person assessment at renewal.

We check this before you apply

As part of our HMO licence application service, we review your property against the full set of mandatory conditions before submission, so you know exactly what's required and aren't caught out by a condition you weren't aware of after the licence is granted. Whether you need a Mandatory HMO Licence application, at £500+VAT, or an Additional HMO Licence application, at £300+VAT, we handle the paperwork and flag any condition your property doesn't yet meet before the council does.
