Section 21 is gone, every tenancy is periodic and the possession, rent and paperwork rules have been rewritten. This Renters’ Rights Act landlord guide walks the portfolio investor through the regime in force since 1 May 2026, and shows how to make the new rules work for you, not against you.
The Renters’ Rights Act: the biggest rewrite since 1988
On 1 May 2026 the Renters’ Rights Act 2025 took effect in England and, in a single day, converted every assured shorthold tenancy in the country into an open-ended periodic tenancy. Fixed terms are no longer merely unenforceable; purporting to grant one can attract a civil penalty of up to £7,000. Section 21 is abolished for new and existing tenancies alike, with a short transition window for notices served before commencement that closes on 31 July 2026, after which any unenforced pre-Act notice lapses; the official guidance on pre-Act possession notices sets out the deadlines. From here on, possession runs exclusively through the revised Section 8 grounds, rent increases run exclusively through the statutory Section 13 process, and tenants may leave at any time on two months’ notice, from day one if they choose.
The Act arrives in phases and the current lull is deceptive. Phase one, the tenancy reforms, is already law; phase two, from late 2026, brings the private rented sector database and the landlord ombudsman, with certain possession grounds unavailable to landlords who have not registered once registration becomes mandatory. A Decent Homes Standard follows later still. The landlords who suffer under new regimes are rarely the deliberate rogues; they are the ordinarily decent operators who miss one prescribed form or one deadline. The Act has been designed so that paperwork failures block possession. Mastering the paperwork is therefore not administration; it is the strategy.
How a tenancy now runs
The periodic tenancy is now the only product. It runs month to month with no end date, and the tenant can serve two months’ notice at any time, expiring at the end of a rent period; a tenant can, in principle, give notice in week one. Break clauses are redundant and rent review clauses are void, including reviews agreed before commencement but taking effect after it. Rent in advance beyond the first period cannot be demanded on new tenancies, which removes the traditional comfort blanket for marginal applicants, and rental bidding is banned: you must advertise a price and may not accept more.
Discriminating against applicants with children or on benefits is prohibited, and a tenant now has a statutory right to request a pet, which the landlord cannot unreasonably refuse, though insurance can be required. Every tenant must also receive the official Renters’ Rights information sheet, which was due to all existing tenants by 31 May 2026; failing to serve it sits among the breaches attracting civil penalties of up to £7,000. Under the old law a mistake cost you a delay. Under the new law it costs you the ground: if a form, a deposit step or a registration is prescribed, treat it as a condition of getting your property back, because in most cases that is exactly what it now is.
Selection is the new security
What does careful selection look like when six months’ rent up front is off the table? Referencing does the work the deposit used to share: verified income, employer and previous-landlord checks, and guarantors where income is thin. The Act does not restrict guarantors, and a properly drafted guarantee is now the single most valuable underwriting tool in the private landlord’s kit.
Documentation matters at the front door too. The deposit must be protected and the prescribed information served, because failure now blocks a Section 8 possession claim on most grounds until remedied. Think of the file you build at the start of a tenancy as the case bundle for a possession claim you hope never to bring; assembled on day one, it costs an hour, but assembled in a crisis, it costs the claim. Reference as if there were no deposit and no possession route, because both are now harder to reach, and file proof of every prescribed step before the tenant collects keys.
The Section 8 map
Possession has not been abolished; it has been re-routed through grounds you must prove, on notice periods you must respect. Arrears lead the list: the mandatory Ground 8 now requires at least three months of unpaid rent (thirteen weeks if rent is weekly) both when the notice is served and at the hearing, on four weeks’ notice, and arrears caused solely by delayed Universal Credit to which the tenant is entitled do not count. The discretionary Grounds 10 and 11 remain for lesser or persistent arrears. Anti-social behaviour under Ground 14 has been broadened to conduct capable of causing nuisance, with notice able to be served immediately.
Two grounds do the work Section 21 used to do: Ground 1, occupation by the landlord or close family, and the new Ground 1A, sale of the property. Both carry four months’ notice, cannot be used in the first twelve months of a tenancy, and carry restrictions on re-letting after use; misusing a ground knowingly or recklessly is itself a penalty offence. Deposit compliance is a precondition for most grounds, commentary differs on some notice periods, and the current prescribed form should be verified before serving.
Arrears management starts at the first missed payment
The practical consequences of the new grounds are worth stating plainly. With a three-month threshold and four weeks’ notice, a landlord who waits for the Ground 8 threshold before engaging is already four months from a hearing date on a good day, so the conversation, the payment plan and the evidence trail start at the first missed payment, with every arrears conversation kept in writing. An intention to sell or move in must be genuine and documented, because tenants, councils and the coming database will police it; never use the moving-in or selling grounds tactically. And the court remains the bottleneck the government has promised to fix; until it does, the premium on avoiding possession through good selection and early engagement has never been higher.
Raising rent the only legal way
Market rents are not capped, but the route to them is now a single statutory path. There is one mechanism: a Section 13 notice on the new prescribed Form 4A, no more than once every twelve months, giving at least two months’ notice of the new rent. Contractual rent review clauses are void, so a portfolio’s rent diary now needs managing centrally: the anniversary of each last increase, minus two months, is the service date, and missing it by a quarter costs you a quarter’s uplift forever.
The tenant may refer the proposed rent to the First-tier Tribunal, which assesses the open market rate; under the Act the tribunal cannot set a rent higher than the landlord proposed, which removes the old deterrent against frivolous referrals, and a referral defers the increase. Expect referral rates to rise, and price accordingly: a defensible increase supported by three comparable listings will survive the tribunal, while an ambitious one invites a delay that costs more than the difference.
The money rules that trip people up
The rest of the money rules are quickly stated but easily tripped over. Advertised price is a ceiling, not an opening bid; accepting an offer above it is a breach. Rent in advance beyond the first period cannot be required on tenancies granted after commencement. Deposits remain capped under the Tenant Fees Act at five weeks’ rent for most tenancies, and the prohibition on miscellaneous fees stands.
The enforcement environment has hardened around all of it: civil penalties of up to £7,000 attach to a widening set of breaches, rent repayment orders have been extended, and once the PRS database arrives, a landlord’s compliance history becomes visible infrastructure. The economics of cutting corners, never good, are now plainly negative. The annual routine matters as much as the rules: serve Form 4A two months before each intended increase with comparables on file, renew gas and electrical certificates, review the licensing position, keep arrears logs contemporaneous, and prepare for database registration when your region opens.
Running the portfolio under the Renters’ Rights Act
Standards enforcement is the quiet half of the reform. Awaab’s law principles are being extended to the private sector, with financial penalties for unaddressed serious hazards taking effect through 2026, and the Decent Homes Standard will follow in a later phase; the direction is that condition failures become enforcement events rather than negotiating points. The sensible response is a maintenance posture that is proactive rather than reactive: damp and mould dealt with at first report, photographed and documented, repairs logged with dates, and a contractor bench that can produce an invoice trail. The same file that protects the tenant protects the landlord, because in any dispute before the coming ombudsman, the party with the contemporaneous records wins, a point PPI has explored in its piece on the lifecycle evidence approach to inspections.
Agents deserve a hard look in this new world. A good one is now processing prescribed forms, statutory notices, database entries and ombudsman correspondence on your behalf, and errors are yours in law even when they are the agent’s in fact. Interrogate their Renters’ Rights training, their form-handling process and their arrears escalation timeline before renewing a management contract, and treat a cheap fee attached to a vague answer as the most expensive option on the table. Self-managing landlords should join a landlord association for the document templates and helpline alone.
The investor’s playbook
The Renters’ Rights Act is survivable, and for professional operators it may prove profitable, because it prices out the casual and the careless. The work has moved: from the back end of the tenancy, where Section 21 used to forgive every error, to the front end, where selection, referencing and paperwork now determine whether you ever see the inside of a courtroom. Build the file on day one, manage arrears from the first missed payment, run the rent diary like a business process, and treat every prescribed form as load-bearing. Do those four things and the new regime is an operating manual, not a threat.
Two further habits of the seasoned post-Section-21 landlord are worth underlining: advertise the rent you mean to achieve, because the asking price is now also the ceiling; and register on the PRS database early, treating a clean public record as a marketing asset. And resist the temptation to disengage because the rules have changed: the same Act that raises your compliance burden is thinning your competition, and thinning competition is rental pricing power.
The bigger picture
The roadmap from here is published, if approximate. Late 2026 brings the first regional rollout of the PRS database, with mandatory registration to follow, and the ombudsman alongside it; a later phase applies the Decent Homes Standard, with implementation stretching towards the 2030s. Layered across it are obligations arriving from other directions: EPC C by October 2030 under the Warm Homes Plan, Making Tax Digital reporting phasing in from April 2026, and the separate property income tax rates from April 2027. Each measure individually is manageable; collectively they amount to the professionalisation of a cottage industry, and each nudges the sector towards the corporate operation PPI has tracked as landlords go corporate in record numbers.
That exodus is the investment context. Fewer landlords chasing an undiminished tenant base is the simplest explanation for rents rising 3.3 per cent nationally in the year to June 2026 on ONS figures, with the North East at 6.3 per cent, even as the wider economy cooled. For the landlord who stays, the strategic questions are court capacity, on which the government has promised reform before further tightening, and the enforcement temperament of individual councils, which varies widely and is worth researching as carefully as yield. The Act has made the private rented sector a worse hobby and, quite possibly, a better business. Position accordingly.
