5 Things Every HMO Landlord Must Do Before May 1st
Why May 1st Is Different From Every Other Compliance Deadline
Most regulatory deadlines in property are soft. Councils send warning letters. You get a chance to remedy. May 1st is not that.
The Renters' Rights Act 2025 received Royal Assent on 27 October 2025, and Phase 1 enforcement begins 1 May 2026. From that date, the entire legal framework governing how you let residential property in England changes simultaneously — tenancy structures, eviction routes, rent increase processes, advertising rules, and discrimination law all shift at once.
According to [realyield.co.uk](https://www.realyield.co.uk/insights/renters-rights-act-compliance-checklist), penalties start at £7,000 per breach and climb to £40,000 for specific or repeated offences. Local councils have been handed new inspection powers and financial incentives to enforce. The Private Rented Sector Ombudsman — when it launches later in 2026 — gives tenants a free complaints route directly against you.
For HMO landlords specifically, the stakes are higher than for single-let operators. More tenants per property means more information sheets to serve, more pet requests to field, more tenancy agreements to review. You're not managing one relationship — you're managing four, five, or six simultaneously under a brand-new rulebook.
Here are the five things I'd do in the next 48 hours.
Step 1 — Send the Government Information Sheet to Every Existing Tenant by 31 May
This one has a hard deadline and a hard fine. If your HMO tenants are on written assured or assured shorthold tenancies created before 1 May 2026, you must deliver the official government Renters' Rights Act Information Sheet to every named tenant by 31 May 2026.
The deadline is 31 May, not 1 May — so you have a small buffer. Use it.
Delivery rules matter here and they're stricter than you'd expect. According to [realyield.co.uk](https://www.realyield.co.uk/insights/renters-rights-act-compliance-checklist), you must either print the sheet and hand or post it, or send the PDF as an email attachment. Sending a link to the government website is explicitly not valid. A text message with a URL is not valid. A verbal mention is not valid.
In an HMO with five tenants, that means five individual deliveries — each documented. If your property is also managed by a letting agent, the NRLA has confirmed both you and the agent carry the obligation independently.
The PDF is published at gov.uk. Download it today, not tomorrow. Failure carries a fine of up to £7,000 per tenancy.
One trade-off worth naming: serving it digitally via email attachment is faster and easier to evidence, but some older tenants may not engage with email reliably. For those tenants, post a hard copy and keep proof of postage. Speed is not worth a dispute over whether delivery actually happened.
Step 2 — Kill Your Section 21 Reliance and Build a Section 8 Evidence Pack
Section 21 is gone. Not reduced, not restricted — abolished, effective 1 May 2026 for all tenancies, new and existing.
If you served a valid Section 21 notice before 30 April 2026, you have until 31 July 2026 to apply for a court possession order before that notice lapses. After 31 July, no new Section 21 claims can be started under any circumstances. As [theindependentlandlord.com](https://theindependentlandlord.com/renters-rights-to-do/) notes, this is specialist legal work — don't attempt it yourself if you're already in that position.
From 1 May, all possession claims run through Section 8 of the Housing Act 1988. The grounds you'll use most often in an HMO context:
Ground 8 — mandatory rent arrears. The threshold has increased from two months to three months' arrears (or 13 weeks for weekly tenancies), and the arrears must exist both when you serve notice and at the court hearing. Notice period increases from two weeks to four weeks.
Ground 14 — anti-social behaviour. Still discretionary, still requires evidence, and in an HMO setting where tenants share communal space, this is the ground most likely to be tested.
Ground 1A — new under the RRA. Allows possession where you genuinely intend to sell. Four-month notice period, cannot be used in the first 12 months of a tenancy. If you use it and then re-let or remarket within 12 months, you're exposed.
What I'd do right now: build a basic evidence pack for each tenancy. Rent payment history, any written communications about behaviour, signed tenancy agreements, inspection records. If you ever need Ground 8 or 14, you'll need this material — and gathering it under pressure during a dispute is significantly harder than doing it calmly now.
Consider consulting a qualified solicitor on your specific possession strategy. This is not an area to improvise.
Step 3 — Audit Your Rent Advertising and Remove Any Bidding Invitations
From 1 May, the way you advertise and collect rent is legally regulated in ways it simply wasn't before.
Three specific rules kick in simultaneously, per [simplybusiness.co.uk](https://www.simplybusiness.co.uk/knowledge/landlord-news/renters-rights-act-checklist/):
First, your advertised rent must be a single fixed figure. No ranges. If you've been listing rooms at "£650-£700 pcm depending on the tenant," that's gone.
Second, rental bidding is banned outright. You cannot invite, encourage, or accept offers above the advertised price. If a prospective tenant volunteers a higher figure, you cannot accept it. This applies to landlords and letting agents equally.
Third, advance rent is capped at one month for new tenancies. You cannot request or hold more than one month's rent before the tenancy begins. This is separate from the security deposit.
For HMO landlords advertising individual rooms, this means every live listing needs checking today. Rightmove, Zoopla, SpareRoom — any platform where you have active adverts. If any of those adverts reference price ranges or invite "best offers," update them before 1 May.
The discrimination rules matter too. From 1 May, landlords cannot refuse applicants because they receive housing benefit or have children. According to [theindependentlandlord.com](https://theindependentlandlord.com/renters-rights-to-do/), any mortgage conditions that previously required you not to let to benefit claimants become unenforceable — and landlord insurance policies with similar restrictions become unenforceable when your current policy expires. Check both.
Step 4 — Switch Your Rent Increase Process to Section 13 and Form 4A
If you've been using rent review clauses in your tenancy agreements to increase rent annually, those clauses are void from 1 May 2026. Not voidable — void. They simply stop working.
From 1 May, the only lawful route to increase rent on an assured periodic tenancy is the Section 13 statutory process using the new Form 4A, as confirmed by [realyield.co.uk](https://www.realyield.co.uk/insights/renters-rights-act-compliance-checklist). The rules:
You can only increase rent once in any 12-month period. You must give at least two months' notice. The proposed new rent and start date must be stated on Form 4A. The old Form 4 cannot be used after 30 April 2026.
For HMO landlords, this is operationally significant. If you're staggering rent reviews across multiple tenants in the same property, each one now needs its own formal Section 13 notice. You cannot do a blanket increase across the house without serving each named tenant individually.
If you wanted to increase rent under the old rules using a Form 4 notice, [theindependentlandlord.com](https://theindependentlandlord.com/renters-rights-to-do/) advises that notice needed to be served by 27 April at the latest — which has now passed. If you haven't served it, you're on the new process.
Download Form 4A from GOV.UK when it becomes available on 1 May and make it your standard template going forward.
Step 5 — Prepare Your Pet Request Response Process
This one catches landlords off-guard because it feels less urgent than eviction law and rent rules. Don't underestimate it.
From 1 May, tenants have an enhanced right to request permission to keep a pet. When a written request arrives, you have 28 days to respond in writing. You cannot simply say no — any refusal must be justified by specific, reasonable grounds. Fail to respond within 28 days and the tenant can refer the dispute to the PRS Ombudsman or apply to the county court, which may order you to grant consent.
In an HMO, the complexity multiplies. A pet in a shared house affects other tenants, communal areas, and potentially your HMO licence conditions. Those are legitimate grounds for refusal — but you need to be able to articulate them clearly and in writing, not just feel they're obvious.
According to [tenancypack.co.uk](https://tenancypack.co.uk/blog/5-things-landlords-must-do-before-may-2026), you cannot force a tenant to contribute to pet damage insurance — any damages must come from the security deposit within the existing cap.
What I'd do: draft a simple pet request response template now, before the first request arrives. It should cover your assessment criteria (property size, communal areas, HMO licence conditions), your response timeline, and any conditions you'd attach to approval. Being organised here protects you and signals professionalism to your tenants.

The landlords who'll feel this transition most painfully aren't the ones with the most properties — they're the ones who've been managing on autopilot, assuming the rules they learned five years ago still apply. They don't. May 1st is a hard reset, and the five steps above aren't suggestions. They're the floor. The HMO operators who treat this as an opportunity to tighten their processes, document everything, and build genuinely professional tenant relationships will come out of 2026 in a stronger position than they entered it. The ones who wait for a council letter will find out what a £7,000 fine feels like. Don't be the second group.
