The maximum penalty for operating an unlicensed HMO rose from £30,000 to £40,000 on 1 May 2026. The penalty applies per offence, not per portfolio. A landlord with five unlicensed properties in an additional licensing area is facing a potential £200,000 in civil penalties before any rent repayment orders are counted.
What Has Happened?
Propertymark, the letting agents' trade body, published guidance this month urging its members and the landlords they manage for to review their compliance position as civil financial penalties under the Renters' Rights Act now sit at a higher ceiling and as local licensing schemes continue to expand across England.
The Renters' Rights Act took effect from 1 May 2026. Phase one of implementation increased the maximum civil financial penalty for relevant Housing Act offences from £30,000 to £40,000. The offences in scope include operating an HMO or other licensable property without the required licence, and failing to comply with licence conditions once licensed. A first-breach penalty, for lower-level non-compliance, sits at up to £7,000. Both landlords and their letting agents are in scope for these penalties.
Alongside the civil penalty, landlords who fail to obtain a required licence face a separate risk: a rent repayment order. Councils and tenants can both seek repayment of up to two years' rent paid during any period the property was unlicensed. This is not a fine. It is a reversal of rental income already received. On a property generating £1,100 per month, a two-year rent repayment order runs to £26,400. That exposure sits on top of any civil penalty, not instead of it.
Enforcement investigations under the Act have specific powers attached. Local authority housing officers can request documents, interview relevant parties, and seize evidence during compliance investigations. Those powers are not unlimited. In routine cases, officers are required to give advance notice before requesting documentation or attending. They cannot compel disclosure of legally privileged material, such as communications with solicitors. The Propertymark guidance specifically addresses what agents and landlords can and cannot lawfully be asked to produce, because its members face the same civil penalty exposure as the landlords whose properties they manage.
The licensing landscape this guidance sits within has been changing. Westminster introduced a borough-wide HMO additional licensing scheme in August 2026. County Durham applied Article 4 directions across further areas in August 2026. Several North West councils have extended or introduced schemes covering significant portions of the private rented sector. The Propertymark warning is not theoretical. The councils where enforcement teams are most active are the same ones where licensing coverage has been expanding fastest.
Why This Matters to UK Property Investors
The penalty-per-offence structure is the first thing investors need to understand. The £40,000 ceiling is not a portfolio-wide limit. A landlord with four properties in an area where additional licensing was introduced in January 2026, who has not yet applied for the required licences, is looking at a potential maximum of £160,000 in civil financial penalties. Add the rent repayment order exposure across those same four properties over 24 months, at a conservative average rent of £900 per month, and the total theoretical liability approaches £260,000. That is not the outcome of every enforcement action. But it is the ceiling councils are now working within.
For letting agents managing third-party portfolios, the direct liability is the development that has not landed widely enough. An agency managing 70 properties across two council areas, with four properties that have not been relicensed after a scheme extension, faces a potential liability of up to £28,000 in civil penalties on those properties alone. The agent's liability runs independently of the landlord's. Getting an enforcement notice as an agent rather than as a principal landlord is not a softer outcome. The penalties are the same.
The PRS Database adds a forward dimension. The government confirmed a regional rollout from late 2026. Once the database is live, properties in mandatory and additional licensing areas that are not registered will be identifiable by council enforcement teams without a physical inspection. An enforcement officer with a screen rather than a clipboard can cross-reference the licensing register against the database at scale. The volume of potential cases that councils can identify changes materially when the identification step becomes desk-based rather than inspection-based.
There is also an overlap risk that is rarely discussed in isolation. A landlord who discovers a licensing failure mid-tenancy and then needs to recover possession because of a difficult tenancy is in a compounding situation. Section 8 possession proceedings are currently averaging 33 weeks from notice to hearing. During those 33 weeks, the rent repayment order clock continues running on the unlicensed property. The civil penalty exposure and the rent repayment order exposure are both accumulating while the possession case grinds through the system. The two liabilities do not cancel each other out.
The Risks Investors Need to Understand
The most exposed landlords are those who grew portfolios between 2015 and 2022 across multiple council areas, and who have not reviewed their licensing position since. Selective and additional HMO licensing is not static. Councils introduce new schemes, extend existing ones, and renew existing ones on rolling timelines. A landlord with properties in Birmingham, Coventry and Wolverhampton is managing three separate licensing frameworks. Each of those councils makes decisions about scheme extensions independently of the others. Keeping track of all three requires active monitoring, not a one-off review.
The HMO mandatory licensing threshold catches properties with five or more occupants in two or more households across three storeys. Most landlords with HMOs know this threshold. What catches them out is additional licensing, which councils can apply to smaller HMOs (typically three or four occupants in two households) in designated areas. Additional licensing coverage across England has expanded significantly since 2020. A four-bedroom HMO that was below the mandatory threshold and outside any additional licensing area in 2021 may have been within an additional licensing area since 2023, with the landlord unaware.
The investigation powers point deserves more attention than it has received. An officer conducting a routine licensing compliance check is working within a defined legal framework. An officer who exceeds that framework, by requesting documentation they are not entitled to or entering a property without the required authorisation, is acting outside their powers. Knowing where those limits are before an officer arrives matters. A landlord or agent who understands that legally privileged correspondence cannot be compelled, and that routine requests require advance notice, is in a different position from one who simply hands over whatever is requested because they assume everything asked for must be lawful.
One practical risk for the investor looking to buy compliance-challenged properties: the licensing history follows the property, not the landlord. Purchasing an unlicensed property does not reset the rent repayment order clock. If a property was unlicensed for the 18 months before a new buyer acquired it, and a tenant pursues a rent repayment order after acquisition, the current owner may face a liability relating to a period before their ownership. Confirming clear licensing status before exchange, and obtaining warranties from the vendor, is not optional due diligence on this type of acquisition.
Where the Opportunity Could Be
The compliance pressure is real, but it is creating a pricing opportunity for disciplined buyers. Landlords who cannot manage the combination of HMO licensing renewal, EPC upgrade work, and the Renters' Rights Act compliance overhead are selling. The vendor motivation is not always visible from the listing, but the pricing sometimes reflects it. A three-bedroom HMO in Birmingham B12 where the vendor is selling partly because the licensing complexity is too much for a portfolio they are managing informally is an asset with intact income-generating characteristics. A buyer who has the management infrastructure to run it compliantly from day one acquires at a price that reflects someone else's operational difficulty.
The buyer pool for compliance-challenged property has thinned. Institutional BTL operators and professional limited company portfolios tend to avoid acquisitions with unresolved licensing issues. That leaves motivated vendors facing a smaller set of qualified buyers. Professional investors who know how to audit and resolve a licensing position before completion, rather than walking away from it, are operating with fewer competitors than they were two years ago on this type of stock.
Northern cities where additional licensing has been expanding, specifically Liverpool, Salford and parts of Greater Manchester, have the most active enforcement environments alongside some of the strongest BTL yields. Liverpool L6 HMOs yielding 9% to 11% on a five-bedroom terrace are not more attractive because of the compliance overhead. They are more attractively priced because the compliance overhead narrows the buyer field. For an investor with a licensing consultant in their corner and a managing agent who knows the Liverpool selective licensing scheme inside out, that narrowing works in their favour.
One tactical angle worth considering: properties currently let under invalid tenancies because the landlord failed to obtain a required licence are at elevated risk of rent repayment order claims. If you are buying in an area with mandatory or additional HMO licensing, asking for evidence of the licence, the date it was issued, and whether it covers the current tenancy start date is not over-cautious. It is the minimum check that protects an incoming buyer from inherited exposure.
Arsh's Investor View
Four months into the Renters' Rights Act, and what strikes me about the enforcement picture is how uneven the understanding is. I know landlords who had their compliance ducks in a row before May 1, who are running licenced portfolios, who have their Information Sheets filed correctly, who are fine. I also know landlords, with portfolios of five to ten properties, who still think the Information Sheet is optional if the tenancy predates May 2026, and who have not checked their HMO licence status against the current additional licensing map for their council area since 2021. Those are not small portfolios. They are significant exposures sitting under the radar of owners who genuinely do not know what they do not know.
The £40,000 ceiling is the number I want to land. When the sector was discussing RRA enforcement in April, the conversation was mostly about the £7,000 Information Sheet fine, because that fine was new and specific and affected everyone with new tenancies immediately. The £40,000 maximum, which existed at £30,000 before and has now increased, received much less coverage. But the licence compliance scenario is where the numbers get genuinely large, because it is the scenario where you have multiple properties, multiple affected tenancies, and the civil penalty running alongside a rent repayment order rather than replacing it.
On investigation powers: I have spoken to agents who have received documentation requests from council officers that were, in my view, wider than what the legislation allows. The officers were not being deliberately obstructive. They were working from their own understanding of what they could ask for. Knowing that legally privileged material is protected, that advance notice is required in routine cases, and that you are not obliged to hand over everything requested just because someone in a council uniform is asking, is the kind of thing worth knowing before you are in that situation. Not during it.
My practical advice: if you have HMOs and you have not looked at the additional licensing map for your council area since 2021 or 2022, look at it this week. The check takes fifteen minutes on the council website. The cost of finding out you need a licence you do not have is far lower at that point than it is after enforcement begins.

Key Takeaways
- From 1 May 2026, the maximum civil financial penalty for operating an unlicensed HMO or breaching licence conditions increased from £30,000 to £40,000 under Renters' Rights Act Phase 1. The penalty applies per offence, not per portfolio. First-breach civil penalties sit at up to £7,000 for both landlords and letting agents.
- Failure to obtain a required licence during a tenancy period exposes landlords to a rent repayment order of up to two years' rent, which councils and tenants can both pursue. This liability runs alongside any civil financial penalty, not instead of it. On a property at £1,100 per month, a two-year rent repayment order adds £26,400 to the civil penalty exposure.
- Local authority housing enforcement officers can request documents and conduct investigations, but their powers are defined by statute. Advance notice is required in routine cases. They cannot compel disclosure of legally privileged material. Knowing those limits before an investigation begins is material for both landlords and the agents managing their properties.
- The PRS Database regional rollout is confirmed from late 2026. Once live, it will allow council enforcement teams to identify properties in mandatory and additional licensing areas that are not registered, without a physical inspection. Properties missing from the register will appear as compliance flags in enforcement systems.
- Additional and selective HMO licensing has expanded significantly across England in 2024 and 2026. Westminster, County Durham and multiple North West councils introduced or extended schemes this year. Landlords who have not reviewed their licensing position since 2021 or 2022 should not assume their current status is unchanged.
- When buying a compliance-challenged property, the licensing history follows the property, not the vendor. An incoming buyer may inherit rent repayment order exposure from an unlicensed period before their ownership if the prior tenancy was affected. Confirming licensing status and the date of issue before exchange is essential due diligence.
Frequently Asked Questions
What is the maximum fine for operating an unlicensed HMO after the Renters' Rights Act?
From 1 May 2026, the maximum civil financial penalty for operating an HMO or licensable property without the required licence is £40,000, increased from £30,000 under Renters' Rights Act Phase 1. This ceiling applies per offence. A landlord with four unlicensed properties is facing a potential maximum of £160,000 in civil penalties. First-breach or lower-level breaches attract civil penalties of up to £7,000. Failure to hold a required licence during a tenancy also opens the landlord to a rent repayment order of up to two years' rent, which can be pursued by the council or by the tenant directly through the First-tier Tribunal.
What can a council enforcement officer lawfully ask for during a Renters' Rights Act investigation?
Council housing enforcement officers investigating licensing compliance can request relevant documents, conduct interviews and seize evidence. However, their powers have limits. In routine investigations, officers must give advance notice before requesting documentation or attending a property. They cannot compel the disclosure of legally privileged material, such as correspondence with solicitors or legal counsel. An officer asking for all emails and tenancy correspondence from the past two years is making a request that may go beyond what they can lawfully require. Propertymark published detailed guidance in September 2026 on what agents and landlords can and cannot be required to produce, which is worth reading before any investigation begins.
Are letting agents liable for HMO licensing compliance under the Renters' Rights Act?
Yes. Letting agents managing properties on behalf of landlords carry direct civil penalty liability under the Renters' Rights Act. An agent who fails to ensure a managed HMO holds the required licence can face a civil financial penalty of up to £7,000 per offence at the first-breach level, or up to £40,000 for serious or repeated breaches. This liability sits alongside the landlord's own liability, not instead of it. Propertymark issued guidance in September 2026 specifically because its letting agent members face the same civil penalty exposure as the landlords they represent, and because HMO licensing coverage has been expanding across England throughout 2026.
How do I find out if my rental property needs a licence?
All properties with five or more occupants forming two or more households across three storeys require a mandatory HMO licence from the relevant local council. Properties below that threshold may still require a licence if the council has an additional licensing scheme covering smaller HMOs in designated areas, or a selective licensing scheme covering all private rented properties in specific postcodes. Check the relevant council's planning and housing pages for your property's address. Licensing schemes are updated as councils introduce, extend and renew them. A property that did not require a licence in 2021 may require one in 2026 if the council introduced an additional or selective scheme in the interim.
What is a rent repayment order and how does it work?
A rent repayment order is a tribunal ruling requiring a landlord to repay some or all of the rent a tenant paid during a period when the landlord was operating unlicensed or committing certain other Housing Act offences. Both the tenant and the local council can apply for a rent repayment order through the First-tier Tribunal. The maximum repayment is two years' rent paid during the period of the offence. A landlord generating £1,000 per month who operated unlicensed for 24 months faces a rent repayment order exposure of up to £24,000. This liability runs alongside any civil financial penalty imposed by the council. The two do not offset each other.
