£40,000 Fines Hit HMO Landlords in 4 Days: What You Must Do Before May 1st

The £40,000 Number Is Real — And It's Not Just for Rogue Landlords

Let me be direct about what's changing. The Renters' Rights Act, which received Royal Assent on 27 October 2025, brings its first enforcement phase into effect on 1st May 2026. Under the updated civil penalty framework — confirmed in the government's own civil penalty guidance — local authorities can now issue penalties of up to £40,000 for serious HMO offences, including operating an unlicensed HMO under Section 72 of the Housing Act 2004, and breaching HMO management regulations under Section 234.

This isn't a theoretical ceiling. We already saw a landlord in Gravesend ordered to pay £34,375 after Gravesham Borough Council pursued him through Dartford County Court for running an unlicensed HMO housing seven people across two families — and that was under the old framework, as reported by [landlordzone.co.uk](https://www.landlordzone.co.uk/news/landlords-licence-dodge-results-in-ps35-000-fine) in April 2026. In Brent, a landlord was fined £91,788 after inspectors found 18 people in a property licensed for seven, including a couple with a four-month-old baby living in an unheated outbuilding, according to [brent.gov.uk](https://www.brent.gov.uk/news-in-brent/2026/march/landlord-hit-with-92k-fine-for-dangerous-and-overcrowded-hmo). From May 1st, councils have stronger tools and higher ceilings. The direction of enforcement is only going one way.

As [footforwardproperties.co.uk](https://www.footforwardproperties.co.uk/new-fines-for-hmo-landlords-under-the-renters-rights-act/) explained in their April 2026 analysis, the key distinction is between a breach and an offence. Paperwork failures and advertising errors can attract penalties up to £7,000. Licensing offences and serious management failures can attract up to £40,000 — or prosecution instead. Not every mistake is equal, but the gap between the two categories is narrowing as councils receive clearer guidance on when to escalate.

The Rakusen v Jepsen Loophole Is Closed — Superior Landlords Are Now Exposed

A close-up, overhead flat-lay of legal documents, a pen, and a set of house keys on a dark oak desk. The documents show dense paragraphs of text but no readable words or numbers. The lighting is cool and clinical — a single desk lamp casting sharp shadows. The mood conveys legal complexity and financial consequence. No faces, no logos, no text visible. Photorealistic style.

This is the part that catches experienced investors off guard. Until now, if you owned a head lease on a property that was sub-let as an HMO — a common structure in rent-to-rent and layered corporate ownership — you had significant protection. The Supreme Court ruling in Rakusen v Jepsen established that rent repayment orders could not be made against superior landlords further up the ownership chain. That protection disappears on May 1st.

Anna Ralston-Crane and Sarah Collins, partners at international law firm CMS, confirmed in analysis reported by [propertywire.com](https://www.propertywire.com/news/superior-landlords-face-hmo-fines-under-new-legislation/) on 22 April 2026 that from May, liability extends to any landlord holding a superior interest in a property that requires a licence but doesn't have one — regardless of their involvement in day-to-day management. The phrase that matters is "regardless of their involvement in day-to-day management." Distance from the tenants is no longer a defence.

For investors who structure holdings through multiple corporate entities, or who hold head leases on properties managed by a rent-to-rent operator, this is a material change in legal exposure. The government's guidance states that where rent-to-rent arrangements are in place, responsibility for a breach or offence may rest with the superior landlord as well as, or instead of, the immediate landlord. That word "instead" is doing serious work.

Statutory defences do remain available. CMS confirmed that demonstrating "all reasonably practicable steps" were taken to ensure a property is licensed can provide protection. But — and this is the part most people gloss over — relying on tenancy agreements that seek to restrict how a property is occupied will not be sufficient. If your defence strategy is "the contract says they can't sublet," that won't hold.

Rent Repayment Orders: The Hidden Cost That Dwarfs the Fine

A dramatic wide shot of a modern UK courtroom interior, empty of people, with wooden benches, high ceilings, and tall arched windows letting in cold grey light. The atmosphere is austere and weighty, evoking legal consequence and institutional authority. The colour palette is muted — dark wood, cream walls, grey light. No text, no signage, no people. Photorealistic style.

Most landlords are focused on the £40,000 headline. I'd argue the rent repayment order changes are actually the bigger financial threat for HMO operators.

From May 1st, rent repayment orders are extended to 24 months' rent — up from 12 months under the previous framework. They now cover company directors, not just individual landlords. And they now apply to superior landlords, closing the structural protection that rent-to-rent investors have relied on for years. [footforwardproperties.co.uk](https://www.footforwardproperties.co.uk/new-fines-for-hmo-landlords-under-the-renters-rights-act/) made this point clearly in April 2026: for HMO landlords, the cost of getting things badly wrong may no longer be just a council fine — it may include repaying up to two years of rent.

Run the numbers on a typical HMO. Say you have a six-bed property in a northern city generating £3,000 per month in rent. A successful rent repayment order at the new maximum means £72,000 back to tenants — on top of any civil penalty. That's not a fine you absorb and move on from. That's a business-ending event for a small portfolio.

The extension to company directors is equally significant. Previously, operating through a limited company offered some structural insulation. From May 1st, directors of companies that own or manage non-compliant HMOs can be named in rent repayment order applications directly. If you set up an SPV to hold your HMO portfolio and assumed the corporate structure was a firewall, you need to revisit that assumption with a qualified solicitor before May 1st.

What HMO Landlords Must Actually Do Before May 1st

I want to be practical here, not alarmist. The landlords most exposed by these reforms are not the ones running tidy, licensed, well-managed HMOs. They're the ones who treat licensing as something to sort later, rely on weak rent-to-rent structures without checking the compliance chain, exceed authorised occupancy levels, or self-manage without the systems the sector now demands — as [footforwardproperties.co.uk](https://www.footforwardproperties.co.uk/new-fines-for-hmo-landlords-under-the-renters-rights-act/) correctly identified in their April 2026 breakdown.

So here's what I'd be doing right now if I were reviewing a portfolio ahead of May 1st.

First, confirm every HMO that requires a licence actually has one — and that the licence reflects current occupancy. A licence for five people in a property housing six is not a compliant property; it's an overcrowding notice waiting to happen. Second, if you hold a head lease or superior interest in any property sub-let as an HMO, get written confirmation from the person beneath you in the chain that the property is licensed. Don't assume. The legal exposure is now yours if it isn't. Third, if you operate through a limited company, speak to a qualified solicitor about what the director-level rent repayment order extension means for your structure specifically. This is not generic advice — the implications depend on how your SPV is set up and what role you play in it.

Fourth — and I'd argue this is the most overlooked item — check your management regulations compliance, not just your licence. Section 234 of the Housing Act 2004 covers fire safety measures in communal areas, water supply, drainage, waste disposal and maintenance of shared parts. These are the failures that move a case from the £7,000 bracket into the £40,000 bracket. A valid licence does not protect you from Section 234 breaches.

Finally, review your tenancy paperwork and rent advertising. From May 1st, landlords cannot market a property without stating the proposed rent, cannot invite offers above the stated rent, and cannot discriminate against tenants with children or those receiving benefits. These rules apply to HMO landlords exactly as they do to any other private landlord — and failures here can still attract civil penalties, even if the property is fully licensed.

Gravesham Borough Council made their position clear after the Sidhu case: "These will only be reinforced when the new Renters' Rights Act comes into force on 1st May, which will give us extra enforcement powers and leave those who flout the law facing increased penalties." Councils are not waiting to see how enforcement beds in. They're telling you exactly what's coming.

The Honest Trade-Off: Compliance Costs Money, But Non-Compliance Costs More

There's a version of this conversation where someone argues that the regulatory burden is disproportionate, that small landlords can't absorb compliance costs, and that the Renters' Rights Act is squeezing legitimate operators out of the market. I have some sympathy for that view — the pace of legislative change since 2022 has been genuinely difficult for self-managing landlords to track.

But I'm going to take the other side. The cases that keep appearing in enforcement news — Gravesend, Brent, and others — aren't stories about good landlords caught by technicalities. They're stories about properties housing seven people without a licence, babies in unheated outbuildings, smoke alarms that don't work. The £40,000 ceiling and the extended rent repayment orders are calibrated to make non-compliance genuinely uneconomical, not just inconvenient. That's the right policy direction, even if the implementation timeline is brutal.

The trade-off is real: proper compliance — licensing fees, professional management, regular inspections, accurate paperwork — costs money and time. But the alternative, as the Brent case demonstrated with a £91,788 fine, is not a viable business strategy. The NRLA's February 2026 webinar confirmed that while few provisions in the Act are HMO-specific, the enforcement powers have been dramatically strengthened across the board. The margin for error has narrowed to almost nothing.

For investors thinking about HMO for the first time: this is not a reason to avoid the sector. HMOs still deliver some of the strongest rental yields available in UK residential property. But entry now requires either a genuine commitment to compliance infrastructure or a partnership with experienced management. The days of treating HMO as a passive investment you can set and forget are over — and honestly, they should have been over long before May 1st.

May 1st isn't the end of HMO investing. It's the end of HMO investing done badly. The landlords who will feel this most sharply are the ones who've been operating on the assumption that enforcement is slow, councils are under-resourced, and the ownership structure provides insulation. All three of those assumptions are now wrong simultaneously. Superior landlord liability is live. Rent repayment orders reach further and cost more. And councils have just received clearer guidance and higher ceilings to work with. The question isn't whether enforcement will intensify — it's whether your portfolio will be on the right side of it when it does.
