Renting a property without the required licence is one of the most serious offences a landlord can commit under UK housing law. Enforcement has intensified significantly since the Renters' Rights Act 2025 came into force, with higher maximum penalties, extended rent repayment orders, and new enforcement duties placed on councils. This guide explains every financial and legal consequence of non-compliance.
Operating an unlicensed HMO is a criminal offence under section 72 of the Housing Act 2004. Renting an unlicensed property in a selective licensing area is a criminal offence under section 95 of the Housing Act 2004. Both offences carry an unlimited fine on conviction in the magistrates' court.
Criminal prosecutions are relatively rare but do occur, particularly for repeat offenders or cases involving serious property conditions. Councils such as Newham, Hackney, and Nottingham have active enforcement teams and a track record of prosecution.
Under section 249A of the Housing Act 2004, inserted by the Housing and Planning Act 2016, councils can issue a civil penalty as an alternative to criminal prosecution for licensing offences. The Renters' Rights Act 2025 increased the maximum civil penalty from £30,000 to £40,000, effective from 1 May 2026.
The Renters' Rights Act 2025 introduced a clearer distinction between two categories of non-compliance:
| Category | Maximum penalty | Description |
|---|---|---|
| Breaches | £7,000 | Non-compliance where the council may impose a penalty but cannot prosecute |
| Offences | £40,000 | Non-compliance where the council may either prosecute or impose a civil penalty |
Operating without a required licence (whether mandatory HMO, additional HMO, or selective) falls into the offences category, meaning the full £40,000 maximum applies.
The MHCLG statutory guidance published in November 2025 sets out starting points for civil penalties based on seriousness. While no specific starting point is prescribed for licensing offences (as conditions vary between councils), the guidance requires councils to develop and publish their own policies considering severity, culpability, harm caused, and deterrent effect.
Civil penalties are increasingly the enforcement tool of choice for councils because they are faster and cheaper than criminal prosecution. The penalty is issued by the council and can be appealed to the First-tier Tribunal (Property Chamber). If not appealed or paid, it can be registered as a local land charge.
Enforcement examples:
A rent repayment order (RRO) is a tribunal order requiring a landlord to repay rent to the tenant or the local authority. The Renters' Rights Act 2025 made significant changes to the RRO regime:
| Change | Before RRA 2025 | After RRA 2025 |
|---|---|---|
| Maximum repayment period | 12 months | 24 months |
| Application window | 12 months after offence | 2 years after offence |
| Applies to superior landlords | No | Yes (rent-to-rent arrangements) |
| Applies to company directors | No | Yes |
| Repeat offenders | Discretionary amount | Must repay maximum amount |
RROs are available under Part 2 of the Housing and Planning Act 2016 where a landlord has committed a relevant offence, including operating an unlicensed property. Key points:
The Renters' Rights Act 2025 extends RROs to several new offences:
Enforcement examples:
Under the previous regime, an unlicensed landlord could not serve a valid Section 21 no-fault eviction notice (section 98 of the Housing Act 2004). Any notice served while the property was unlicensed was void.
The Renters' Rights Act 2025 abolishes Section 21 entirely. However, the principle that licensing non-compliance blocks possession proceedings is preserved under the new regime. A landlord who does not hold the required licence will face restrictions on their ability to recover possession of the property through the courts.
Under Part 2 of the Housing and Planning Act 2016, a council can apply to the First-tier Tribunal for a banning order against a landlord who has committed a banning order offence. Operating an unlicensed HMO or unlicensed property in a selective licensing area is a banning order offence.
A banning order prevents the landlord from:
The minimum duration of a banning order is 12 months. Breaching a banning order is a criminal offence. Banning orders are recorded on the Database of Rogue Landlords and Property Agents, which is maintained by MHCLG.
The Renters' Rights Act 2025 places a new statutory duty on local housing authorities to take enforcement action in relation to housing offences. This means councils can no longer choose to ignore licensing breaches. Combined with the enhanced investigatory powers granted by the Act, enforcement activity is expected to increase significantly from 2026 onwards.
The simplest way to avoid penalties is to check whether your property requires a licence before letting it out. Use the Tuxa property licence checker to check any UK address against all active licensing schemes across all 361 councils.
If your property is in a licensing area, apply for the licence before the scheme comes into force. Most councils allow landlords to apply in advance of a scheme's start date. Operating under a pending application does not constitute an offence, provided the application was made before the scheme came into force.
Set up a property alert on Tuxa to receive monthly notifications if the licensing status of your property changes.
Ignorance of the law is not a defence. Councils are not required to notify individual landlords that a licensing scheme has been introduced, though most do publicise new schemes. It is the landlord's responsibility to check whether a licence is required for their property.
A civil penalty is issued by the council without a court hearing. A fine is imposed by a court following criminal prosecution. Both can be substantial, but a criminal conviction carries additional consequences including a criminal record and potential impact on future licence applications.
Yes. Tenants can apply directly to the First-tier Tribunal for a Rent Repayment Order without any involvement from the council. They do not need the council to have taken enforcement action first.
