The Complete Guide to the Renters’ Rights Act for UK Landlords

When the Renters’ Rights Act took effect on 1 May 2026, it did not tweak the rules of letting in England. It rewrote them. Section 21 is gone, fixed terms are gone, and the paperwork that used to be a formality is now the difference between winning possession and being turned away at the court door.

For most landlords the practical question is not whether the Act is a good idea, but what they now have to do differently. This guide walks through the changes that matter, in the order they are likely to affect you, and flags the compliance steps that quietly decide whether a possession claim ever gets heard.

Section 21 has been abolished

The no-fault eviction is finished. You cannot serve a Section 21 notice on any tenant, whenever their tenancy began. Every route to possession now runs through Section 8 of the Housing Act 1988, served on the new Form 3A, and every Section 8 claim has to name a specific statutory ground.

This is the change everything else hangs off. If Section 21 was your safety net, the net is gone, and the grounds you plead now carry the entire weight of the case. It is worth knowing the arrears grounds in particular: Ground 8 (mandatory possession once arrears reach the threshold), Ground 10 (some rent unpaid), and Ground 11 (persistent late payment).

Fixed terms are gone; every tenancy is periodic

All tenancies are now periodic from the first day. There is no fixed end date to hold a tenant to, and a tenant can leave on two months’ written notice whenever they choose. Tenancies that were mid fixed term on 1 May converted automatically; any fixed end date clause simply stopped having effect.

One consequence catches people out. With no renewal point to build a rent review into, every increase now runs through a Section 13 notice on Form 4A, with a minimum two months’ notice and, on top of the once-a-year limit, no increase at all permitted in the first 12 months of a tenancy.

You now have to consider pet requests

A tenant can request a pet in writing, and you must give a reasoned decision within 28 days. A flat refusal without grounds is no longer an option. Legitimate reasons to decline include a head lease that forbids pets, a property genuinely unsuited to one, or evidence of allergies among other occupants.

Refuse without a reasonable basis and the tenant can take the decision to the First-tier Tribunal. The practical defence is a paper trail: log the request, record your reasoning, and respond inside the 28 days.

The Information Sheet is now mandatory

Every tenant must be served the government’s official Information Sheet, new tenants at the start and existing tenants by the commencement date. It reads like a formality, but failing to serve it is a compliance breach that can undermine a later Section 8 notice, so it belongs on the same checklist as the deposit and the certificates.

What you must have in place before you can seek possession

A Section 8 notice has no legal effect unless the tenancy’s compliance basics were handled correctly first. Before serving, you need to be able to evidence all of the following:

• Deposit protected in an approved scheme within 30 days of receipt, with the prescribed information served on the tenant
• Gas Safety certificate current within 12 months, served before the tenant moved in and within 28 days of each renewal
• EICR served on the tenant
• EPC rated E or above, served on the tenant
• How to Rent guide (current version) served at the start of the tenancy
• Information Sheet served on the tenant

Miss one and a court will refuse to hear the claim. Landlords who leaned entirely on Ground 8 have been sent away because a single certificate had lapsed, which is exactly the kind of avoidable gap that costs months.

What is coming next

The changes above all arrived with a hard date. Behind them sits a second wave the Act enables but has not yet switched on: Awaab’s Law hazard deadlines are expected to reach private tenancies, and a mandatory landlord database, a new Ombudsman, and an extended Decent Homes Standard are all on the roadmap between now and 2035. None of it is live. None of it is worth waiting on either.

This is where keeping a clean record now pays off later. STEMHQ is built so each new obligation becomes a software update rather than a scramble: a timestamped maintenance and hazard log answers an Ombudsman complaint with evidence instead of recollection, the compliance vault already tracks the certificates a Decent Homes Standard will lean on, and unregistered properties are flagged before a landlord database goes live. The roadmap of what is changing next sets out how each stage is handled.

Common misconceptions

Most of the trouble landlords run into after the Act comes not from the headline changes, which are widely understood, but from assumptions carried over from the old regime. These are the ones that surface most often.

“My tenant is still in their fixed term, so the old rules apply to me.”

They do not. Every fixed term converted to a periodic tenancy on 1 May 2026, whatever the agreement says. If you are waiting for a fixed term to run out before the Act touches you, you have already been operating under it for months.

“Ground 8 is mandatory, so if the arrears are high enough the case is a formality.”

Ground 8 is only as strong as the compliance behind it. An unprotected deposit, a lapsed Gas Safety certificate, or an unserved Information Sheet will get the claim dismissed before the arrears are even considered. The ground is mandatory; the pre-conditions are not optional.

“I can raise the rent whenever I like, as long as I give notice.”

No. Increases run through a Section 13 notice on Form 4A, with two months’ notice, no more than once every 52 weeks, and none at all in the first 12 months of a tenancy. A rent-review clause in an old agreement does not survive.

“A partial payment before the hearing won’t matter if the arrears were high when I served.”

It matters entirely. The Ground 8 threshold is tested twice, at service and at the hearing. A tenant who drops a pound below three months’ rent the night before defeats the mandatory ground, which is why Grounds 10 and 11 should always be pleaded alongside it.

Situations landlords are finding themselves in

A few scenarios are coming up again and again as the Act beds in. If any of these describes your position, the answer is usually the same: fix the compliance record first, then act.

Served an old-style notice just before commencement

Someone who served a Section 21 or old Section 8 notice shortly before 1 May 2026, and now wants to rely on it, is in the most fact-specific position of all. Transitional savings are narrow. This is the one scenario where paying a housing solicitor to check the notice before issuing proceedings almost always pays for itself.

Inherited a managed portfolio with patchy paperwork

Landlords who took over tenancies from a previous agent, or moved a book between agents, frequently find the deposit protection or prescribed information cannot be evidenced. The tenancy runs fine until the day possession is needed, at which point the gap becomes the whole case. The conversion is the moment to audit historic files, because a tenant’s adviser certainly will.

A tenant on Universal Credit falling into arrears

Where arrears are caused by Universal Credit processing delays, those amounts are excluded from the Ground 8 calculation by statute. Landlords in this position often assume the mandatory ground is available when it is not yet, and are better served pursuing an Alternative Payment Arrangement to stop the arrears growing while the claim resolves.

A written pet request sitting unanswered

A request that has been left in an inbox past 28 days is already a problem. Silence can be treated as an unreasonable refusal, and the tenant can take it to the First-tier Tribunal. A dated, reasoned response, even a refusal on legitimate grounds, is the protection.

What non-compliance actually costs

The figures below are illustrative of how costs arise under the enforcement regime, not citations of specific named judgments. They show the mechanisms, because the mechanisms are what repeat.

• A possession claim struck out for a compliance gap. Where a deposit was protected late or a certificate had lapsed, courts dismiss the claim outright. The direct cost is the court fee and any legal spend, but the real cost is the delay: the notice clock restarts from day one while arrears keep accruing, routinely adding six months or more of unrecoverable rent.
• A rent repayment order.Where a landlord has let without a required licence or breached prescribed requirements, the First-tier Tribunal can order repayment of up to 12 months’ rent to the tenant or the local authority. On an average tenancy that is comfortably a five-figure sum, separate from any penalty.
• A civil penalty for a compliance breach. Local authorities can impose a penalty of up to £7,000 for a first breach and up to £40,000 for a serious or repeat breach, as an alternative to prosecution, with no court hearing required.
• A prohibited rent or bidding breach. Accepting rent above the advertised figure, or running informal bidding, carries the same £7,000-to-£40,000 civil penalty tier, applied per breach.

None of these require a landmark case to bite. They are administrative and tribunal-level outcomes that a single missing document can trigger, which is why the compliance record, not the strength of the grievance, tends to decide how these end.

Frequently asked questions

Can I still use Section 21 for tenancies that started before the Act?

No. Section 21 is abolished for every tenancy, including those pre-dating the Act. Possession runs through Section 8 on Form 3A.

What happened to my existing fixed-term agreements?

They converted to periodic tenancies on the commencement date. Any fixed end date clause no longer has effect.

Do I need to re-serve the How to Rent guide?

If you served it at the start of a still-valid tenancy, no, unless you renew on new terms. You do, however, need to serve the new Information Sheet on existing tenants.

What are the penalties for non-compliance?

A civil penalty of up to £7,000 for a first breach, rising to up to £40,000 for serious or repeat breaches. Courts can also make rent repayment orders of up to 12 months’ rent.
