Landlord and Tenant Disputes in London: Rights and Legal Remedies in 2026

Landlord and tenant disputes in London have always been a fact of life in one of the world’s most expensive rental markets, but 2026 has genuinely changed the rules of the game. The Renters’ Rights Act 2025 came into force on 1 May 2026, scrapping Section 21 “no-fault” evictions and rewriting how possession, rent increases, and disrepair claims work across England. If you’re a tenant in Hackney worried about a mouldy bathroom, or a landlord in Croydon trying to work out how to regain your flat, the ground has shifted under everyone’s feet.

This guide walks through what’s actually changed, what hasn’t, and what you can do about it. We’ll cover the main categories of landlord tenant disputes, the legal remedies available to both sides, and where in London you can actually go for help, whether that’s the County Court, the First-tier Tribunal, your local council, or free advice services. This isn’t a dry legal textbook. It’s meant to be the kind of practical explanation you’d want from a friend who happens to know housing law, written for people trying to solve a real problem: a deposit that hasn’t come back, a landlord who won’t fix the boiler, or a tenant who’s stopped paying rent.

Whether you’re renting a studio in Zone 2 or letting out a portfolio of HMOs, understanding your rights and legal remedies in 2026 is the difference between resolving a dispute quickly and ending up stuck in a months-long standoff.

Understanding the Legal Framework Governing Landlord and Tenant Disputes in London

London rentals sit within England’s national housing law, but the capital has its own pressures: sky-high rents, a dense concentration of Houses in Multiple Occupation (HMOs), and boroughs that run their own licensing schemes on top of national rules. Several layers of law apply at once:

• The Housing Act 1988, which still underpins the basic structure of assured tenancies, even though it’s been significantly amended.
• The Renters’ Rights Act 2025, the biggest shake-up to the private rented sector in over thirty years, now in force as of 1 May 2026.
• The Housing Act 2004, which governs HMO licensing, selective licensing, and the Housing Health and Safety Rating System (HHSRS) that councils use to assess disrepair.
• The Homes (Fitness for Human Habitation) Act 2018, which gives tenants a direct right to sue if their home isn’t fit to live in.
• The Protection from Eviction Act 1977, which makes illegal eviction and harassment a criminal offence.
• Local borough rules, including selective and additional licensing schemes that apply in parts of London such as Newham, Croydon, and Waltham Forest.

Because so many of these pieces interact, a single dispute (say, a landlord trying to evict a tenant who’s complained about damp) can touch tenancy law, HMO licensing, environmental health law, and criminal law all at once. That’s part of why landlord and tenant disputes in London so often need proper legal or professional advice rather than guesswork.

The Renters’ Rights Act 2025: What Changed in 2026

If you take away one thing from this article, it’s this: Section 21 no-fault evictions are gone. That single change reshapes almost every other dispute discussed below, because it removes the landlord’s old fallback option of simply not renewing a tenancy without giving a reason.

Abolition of Section 21 “No-Fault” Evictions

Section 21 notices could no longer be validly served after 30 April 2026. From 1 May 2026, every existing assured shorthold tenancy automatically converted into an assured periodic tenancy, and any Section 21 notice served before that date only remains enforceable if the landlord applies to court within strict time limits (broadly, within three months of the new rules taking effect). After 31 July 2026, courts will not accept any new applications based on an old Section 21 notice at all.

In practice, this means a London landlord who wants their property back can no longer simply serve two months’ notice and wait. They now have to rely on Section 8, which requires stating a specific legal ground for possession, such as rent arrears, wanting to sell the property, or moving in a close family member. For tenants, this is a major shift toward security of tenure. For landlords, it means the eviction process is slower, more procedural, and much less forgiving of paperwork mistakes.

New Section 8 Grounds for Possession

To balance the loss of Section 21, the government expanded and reworked the Section 8 grounds. Some of the changes most relevant to London disputes include:

• Landlords who want to sell the property or move in themselves or a close family member must now give four months’ notice, and can’t use this ground within the first 12 months of a new tenancy (known as the “protected period”).
• If a landlord uses this ground to regain possession, they generally can’t re-let the property for 16 months from when notice was served, which is designed to stop landlords misusing the ground just to reset the tenancy and raise the rent.
• Rent arrears grounds have been adjusted, with revised notice periods and thresholds.
• Grounds relating to student lets in HMOs have been updated to reflect the loss of fixed-term contracts.

For landlords with property in London, where the temptation to “reset” a tenancy at a higher rent has always been strong, these anti-avoidance measures are worth taking seriously. A local authority can issue a civil penalty of up to £7,000 for a single breach of the new rules, and repeat or serious breaches can lead to unlimited fines or banning orders.

Periodic Tenancies Replace Fixed-Term ASTs

Fixed-term assured shorthold tenancies effectively no longer exist for new agreements. Every private tenancy is now a rolling periodic tenancy, with rent charged no more than monthly and landlords barred from demanding large sums of rent in advance. Tenants can generally end a periodic tenancy with two months’ notice at any point, which gives renters more flexibility but also means landlords have less certainty about how long a tenant will stay.

For a full breakdown of the transitional rules and dates, the UK Government’s official guidance on the Renters’ Rights Act is the most reliable and regularly updated source, since implementation details continue to be refined.

Common Types of Landlord and Tenant Disputes in London

Most landlord and tenant disputes fall into a handful of recurring categories. Knowing which bucket your situation falls into helps you figure out which legal remedy actually applies.

Rent Arrears and Non-Payment

This remains the single most common reason landlords seek possession. Under the new Section 8 rules, arrears grounds are still available, but the notice periods and the amount of arrears required have been recalibrated. Landlords need to keep clear records: rent statements, bank transfers, and any communication about payment plans, because courts scrutinise this evidence closely, especially now that Section 21 is no longer an option to fall back on if a Section 8 arrears case is weak.

Tenants struggling with arrears shouldn’t wait for a court date to act. Options include:

1. Negotiating a repayment plan directly with the landlord or agent.
2. Applying for a Discretionary Housing Payment through the local council.
3. Getting free advice from Citizens Advice or Shelter before arrears escalate.
4. Checking eligibility for Universal Credit housing element backdating.

Disrepair and Poor Housing Conditions

London’s older housing stock, combined with high occupancy in converted flats and HMOs, means disrepair disputes are extremely common. Under the Homes (Fitness for Human Habitation) Act 2018, tenants can take their landlord to court directly if the property isn’t fit to live in, without needing the council to intervene first. Landlords have a duty to keep the structure, exterior, and installations (heating, water, electrics) in good repair.

Awaab’s Law, originally introduced for social housing after the death of two-year-old Awaab Ishak from prolonged exposure to mould, is being extended to the private rented sector as part of the Renters’ Rights Act rollout. Once in force for private tenancies, it will impose strict timeframes for landlords to investigate and fix serious hazards like damp and mould, rather than leaving tenants to chase repairs for months.

If a landlord ignores repair requests, tenants can:

• Report the issue to the council’s environmental health team, who can inspect under the Housing Health and Safety Rating System and issue improvement notices.
• Start a disrepair claim in the County Court for compensation and an order requiring repairs.
• In serious cases, apply for a Rent Repayment Order if the property should have been licensed as an HMO and wasn’t.

Deposit Disputes

Deposit protection remains one of the most litigated areas of landlord and tenant disputes in London. Any deposit taken for an assured shorthold (now periodic) tenancy must be protected in a government-approved scheme, such as the Deposit Protection Service, MyDeposits, or the Tenancy Deposit Scheme, within 30 days of receipt. Landlords must also give tenants prescribed information about where the deposit is held.

If a landlord fails to protect the deposit correctly, tenants can apply to court for compensation of between one and three times the deposit amount, on top of getting the deposit itself back. This is one of the few areas where the financial risk sits almost entirely with the landlord, so getting deposit protection right is non-negotiable.

Common deposit dispute scenarios include:

• Landlords deducting for “wear and tear” that isn’t legally deductible.
• Disputes over cleaning costs at the end of a tenancy.
• Disagreements about damage versus fair usage, often resolved through the scheme’s free alternative dispute resolution (ADR) service rather than court.

Illegal Eviction and Harassment

With Section 21 gone, there’s understandable concern that some landlords may try to pressure tenants out informally rather than going through the proper Section 8 court process. This is illegal. Under the Protection from Eviction Act 1977, it’s a criminal offence to evict a tenant without a valid court order, or to harass them into leaving by cutting off utilities, changing locks, or persistent intimidation.

Victims of illegal eviction can:

• Report it to the police and the local council’s tenancy relations or housing enforcement team.
• Seek an injunction to be let back into the property.
• Claim damages, which can be substantial, particularly where a landlord has acted deliberately.

Rent Increase Disputes

Under the new rules, landlords can only raise rent once a year using a Section 13 notice, and tenants who think an increase is above market rate can challenge it at the First-tier Tribunal (Property Chamber) without paying a fee. Crucially, rent can no longer be increased simply by inserting a rent review clause into the tenancy agreement; the formal Section 13 process is now the only lawful route, which closes a loophole some landlords previously used to raise rent more frequently than intended.

Tenant Rights in London Landlord and Tenant Disputes

Tenant protections have expanded considerably as part of the 2026 reforms. Key tenant rights now include:

• The right not to be evicted without a valid Section 8 ground and a court order.
• The right to request a pet in the property, with landlords unable to unreasonably refuse (though they can require pet insurance).
• The right to challenge rent increases at tribunal without financial risk of the rent going up further as a result.
• The right to a written statement of tenancy terms, even where the agreement was originally verbal.
• Protection from discrimination against tenants receiving benefits or with children, which is now explicitly banned under the Act.
• The right to have deposits protected and repair issues addressed within legally defined timeframes.

These rights don’t mean tenants can ignore their own obligations, such as paying rent on time and not causing damage, but they do shift the balance of power in disputes noticeably compared to the pre-2026 landscape.

Landlord Rights and Obligations

It’s worth being clear that landlords haven’t lost all their tools, even though Section 21 is gone. Landlord rights in 2026 still include the ability to:

• Regain possession for rent arrears, anti-social behaviour, property damage, or wanting to sell or move in, using the appropriate Section 8 ground.
• Increase rent annually via a Section 13 notice, in line with the local market.
• Refer serious rent arrears or persistent breaches to court for a mandatory possession order.
• Screen prospective tenants through referencing and affordability checks, provided this doesn’t stray into unlawful discrimination.

In exchange, landlords carry heavier compliance obligations than before: providing the government’s Renters’ Rights information sheet to tenants, keeping up with HMO and selective licensing requirements in relevant London boroughs, and preparing for mandatory registration on the new Private Rented Sector Database once it launches later in 2026. Getting this wrong isn’t just risky for a landlord’s reputation; it can directly undermine their ability to obtain a valid possession order in court.

Legal Remedies and Where to Seek Help

Whichever side of a dispute you’re on, London offers several formal and informal routes to resolve it. Picking the right one saves time and money.

County Court Possession Proceedings

Most contested evictions and rent arrears cases end up here. Landlords must follow the correct Section 8 notice procedure and use the current prescribed form; getting this wrong is one of the most common reasons possession claims fail or get delayed. Because London’s county courts (particularly the Central London County Court, which handles a large volume of housing cases) are under significant pressure, landlords should expect proceedings to take longer than the statutory minimum notice period alone would suggest.

First-tier Tribunal (Property Chamber)

This is the go-to venue for rent increase challenges, disputes over service charges in leasehold and some rented properties, and certain licensing appeals. It’s designed to be more accessible than court, generally without the same cost risk, and is a good option for tenants who want to challenge a rent rise without the intimidation factor of a courtroom.

Rent Repayment Orders

If a landlord has committed certain offences, such as operating an unlicensed HMO, illegally evicting a tenant, or breaching a banning order, tenants (or the council) can apply to the First-tier Tribunal for a Rent Repayment Order, potentially recovering up to 12 months of rent paid. This has become an increasingly popular remedy in London given the high concentration of shared houses and licensing requirements across boroughs.

Local Council Enforcement

London boroughs have real enforcement teeth. Environmental health officers can inspect properties under the Housing Health and Safety Rating System, issue improvement notices for hazards like damp, mould, or unsafe electrics, and prosecute or fine landlords who ignore them. Many boroughs, including Newham, Waltham Forest, and parts of Croydon, also run selective licensing schemes requiring landlords to license every rental property in designated areas, not just HMOs. Renting out an unlicensed property in one of these zones can itself trigger a Rent Repayment Order claim.

Mediation and Alternative Dispute Resolution

Not every dispute needs court. Deposit scheme ADR services resolve the vast majority of deposit disagreements without a hearing. Some London boroughs and housing charities also offer free mediation for neighbour disputes, noise complaints, or communication breakdowns between landlord and tenant that haven’t yet escalated into a legal claim. Mediation is faster, cheaper, and often preserves the relationship better than litigation, which matters if the tenancy is going to continue.

For general advice on tenant rights and how to navigate a dispute step by step, Shelter’s housing advice service is a well-established and free resource that’s kept up to date with legislative changes.

The New Private Rented Sector Database and Ombudsman

Two further pieces of the Renters’ Rights Act puzzle are still being rolled out. From late 2026, a Private Rented Sector Database will require every private landlord in England to register themselves and their properties, creating a central record that councils can use to track compliance and enforcement history. Landlords who fail to register are likely to face financial penalties and may struggle to enforce their rights against tenants, including in possession proceedings.

Following the database, a Private Rented Sector Ombudsman will give tenants a free, independent route to raise complaints about their landlord without going to court, similar to how disputes with social housing landlords are currently handled. Mandatory landlord membership isn’t expected until around 2028, but landlords and tenants alike should keep an eye on the rollout, since it will eventually become one of the primary channels for resolving disputes that don’t need full legal proceedings.

London-Specific Considerations

A few factors make landlord and tenant disputes in London distinct from the rest of England:

• Selective and additional licensing: Many boroughs require licences for rental properties well beyond the national HMO rules. Always check your specific borough’s requirements, since licensing gaps are a common and costly landlord mistake.
• High rents mean high stakes: With average London rents among the highest in the UK, arrears build quickly, and deposit disputes tend to involve larger sums, making early resolution more financially important on both sides.
• HMO density: Shared housing is far more common in London than in most of the country, which means Rent Repayment Order claims and HMO licensing disputes come up disproportionately often.
• Court backlogs: London’s county courts handle a heavy caseload, and possession claims here can take noticeably longer than the national average, something both landlords and tenants should factor into their planning.

Step-by-Step: What To Do If You’re in a Dispute

1. Read your tenancy agreement carefully. Many disputes hinge on what the contract actually says, particularly around rent, repairs, and notice periods.
2. Put everything in writing. Emails and text messages create a paper trail that’s invaluable if the dispute escalates to tribunal or court.
3. Identify which legal remedy fits. A repair issue needs a different route than a rent increase challenge or a possession dispute.
4. Get free advice early. Citizens Advice, Shelter, and some borough-run housing advice services can clarify your position before you commit to a formal process.
5. Try to resolve it directly or through ADR first. Court and tribunal should generally be a last resort, not a first move.
6. Keep to deadlines. Notice periods, tribunal application windows, and court response deadlines are strict, and missing them can seriously weaken your position.

When to Get a Solicitor

Simple disputes, like a straightforward deposit disagreement or a first-time rent increase challenge, can often be handled without a lawyer, especially using the free tribunal and ADR routes described above. But it’s worth instructing a solicitor who specialises in housing law when:

• You’re facing possession proceedings and risk losing your home.
• A landlord is pursuing a large rent arrears claim against you.
• You’re a landlord dealing with a tenant who won’t leave after a valid Section 8 notice and court order.
• There are allegations of illegal eviction or harassment, given the criminal law dimension.
• The dispute involves licensing breaches that could trigger significant fines or a Rent Repayment Order.

Many housing solicitors in London offer a free initial consultation, and some disputes may qualify for legal aid depending on income and the nature of the case, so it’s always worth checking eligibility before assuming legal advice is out of reach.

Conclusion

Landlord and tenant disputes in London in 2026 look genuinely different from a few years ago. The abolition of Section 21 under the Renters’ Rights Act 2025 has removed landlords’ old no-fault eviction route, replaced fixed-term tenancies with rolling periodic ones, and tightened the rules around rent increases, repairs, and licensing, all while adding new enforcement tools like Rent Repayment Orders and, eventually, a dedicated Private Rented Sector Ombudsman. Tenants now have stronger protection against unfair eviction and disrepair, while landlords retain clear, if more procedural, routes to possession when they have valid grounds.

Whether the dispute is about unpaid rent, a deposit that’s gone missing, mould that won’t clear, or a landlord who’s overstepped the line, the right move is almost always the same: understand which legal remedy actually applies to your situation, act early, document everything, and use the free advice and tribunal services available before things escalate into costly litigation. Getting familiar with these rights and remedies now will save both landlords and tenants a great deal of stress as the rest of the Renters’ Rights Act continues to roll out over the coming months.
