Your landlord has ignored three emails about the boiler. Or they turned up unannounced again. Or they're threatening to evict you two weeks after you raised a repair issue. Whatever the specific problem, you have options, and more of them than most tenants realise.
This guide covers every route available to you: starting a paper trail, escalating to your local council, filing with the Housing Ombudsman, taking a claim to tribunal, and pursuing financial compensation where the law allows it. The Renters' Rights Act 2025 added real teeth to enforcement, with enhanced penalties for serious breaches. That changes how seriously your complaints get treated.
Complaining about your landlord is less about confrontation and more about process. Follow the right steps in the right order, keep evidence, and the system generally works in your favour.
Start with a written complaint to your landlord
Before you involve anyone else, put your complaint in writing. A written complaint creates a timestamped record that every authority you might involve next, from your local council to a tribunal, will want to see.
Send an email or letter that describes the problem specifically, states what you want done about it, and sets a clear deadline. 10 to 14 days is reasonable for most repair issues. For example, "The boiler has not produced hot water since 14 March. Please arrange a repair within 14 days of this letter."
Do not rely on verbal conversations. A WhatsApp message is better than a phone call. An email is better than a WhatsApp message. If you have been communicating verbally up to now, start a written summary. For example, "Following our conversation on Tuesday, I am confirming that I raised the following issue."
A template helps here, because the wording signals to your landlord that you know your rights. A vague complaint is easier to ignore than one that cites the Landlord and Tenant Act 1985 and names a specific obligation.
If your landlord responds and commits to a fix, document that too. If they miss the deadline, you have a clear paper trail showing you gave them a fair chance. That trail becomes your evidence.
What your local council can do about a bad landlord
Your local council has real enforcement powers, and they are free to use. Most councils have a private rented housing team or an environmental health department that handles complaints about rented properties. This is the right route for physical problems: mould, damp, broken heating, pest infestations, structural hazards, missing fire safety equipment.
The council can inspect your property under the Housing Health and Safety Rating System (HHSRS). If they find a serious hazard, they can issue an improvement notice requiring your landlord to fix it. If the landlord ignores that, the council can carry out the work themselves and charge the landlord for it. They can also prosecute landlords who breach licensing rules, including houses in multiple occupation (HMOs) that are operating without the required licence.
For licensing violations specifically, including unlicensed selective licensing areas, this enforcement route connects directly to your ability to claim back rent. An unlicensed landlord is in breach of law, which opens the door to a Rent Repayment Order of up to 2 years' rent (12 months for offences before 1 May 2026).
To complain to your council, find the private rented housing team on your local council's website. Some councils have online complaint forms; others ask you to email or call. Include your address, a description of the problem, and the evidence you have gathered. If the issue is urgent, such as a gas leak, no heating in winter, or a structural risk, say so explicitly and ask for an urgent inspection.
Under the Renters' Rights Act 2025, councils received additional enforcement tools and the authority to issue civil penalty notices up to £40,000 for the most serious landlord breaches. That is a meaningful deterrent, and councils are being pushed to use it.
If you are in Hackney, Islington, or Westminster, selective licensing rules add another layer to this. See the guides for Hackney selective licensing 2026 and Islington selective licensing 2026 for borough-specific details.
When to escalate to the Housing Ombudsman
The Housing Ombudsman handles complaints about social landlords, housing associations, and some registered providers. If you rent from a private landlord directly, the Ombudsman route is not your primary option, though this is changing.
The Renters' Rights Act 2025 requires private landlords to join a new Private Rented Sector Ombudsman scheme. Once operational, private tenants will have a structured escalation route if their landlord fails to respond to complaints. The scheme is designed to resolve disputes without going to court, which matters because court proceedings take time and money.
If your landlord is already part of a redress scheme (letting agents in England have been required to join one since 2014), you can complain through that scheme if initial complaints go ignored. The Housing Ombudsman process follows a clear escalation path: you raise the complaint with the landlord or agent, wait for a response, and if the response is inadequate or absent you escalate to the Ombudsman.
The scheme is not live yet, so for now the council remains the direct route for enforcement. The Private Rented Sector Landlord Ombudsman guide explains how it will work and where the timetable has got to.
Ombudsman processes are slower than a letter before action or a council referral. If you need something fixed urgently, start with the council. Use the Ombudsman route for unresolved disputes where you want a formal decision without going to tribunal.
How to use a letter before action when complaints are ignored
A letter before action is a formal notice that you intend to take legal proceedings if the issue is not resolved. It is not a solicitor-only document. You can send one yourself, and it frequently works.
The reason it works is psychology. A standard complaint email can be filed away and forgotten. A letter before action tells your landlord that you are one step from a court claim, a tribunal application, or a formal enforcement referral. Most landlords would rather sort the problem than deal with those consequences.
The letter should set out the legal basis for your claim, the specific breach, the remedy you are seeking, and a deadline for response, typically 14 days. If you are chasing a deposit that has not been protected, cite Section 213 of the Housing Act 2004. If you are claiming for disrepair, cite Section 11 of the Landlord and Tenant Act 1985. Specific statutory references carry more weight than general complaints.
Pat recovered his £1,000 tenancy deposit within 24 hours of sending a letter before action drafted through Remedy Legal. His landlord had been ignoring him for months. The letter changed the dynamic immediately. You can read how that worked in the full case study.

Which tribunal or court handles landlord disputes in England
If complaints and letters have not resolved the issue, formal proceedings are the next step. The right forum depends on what you are claiming.
The First-tier Tribunal (Property Chamber) handles most housing disputes between private landlords and tenants in England. This includes rent repayment orders, challenges to a rent increase (your landlord proposes it by a Section 13 notice, and you apply to the tribunal for a Section 14 determination), and disputes about property conditions. It is not a court in the traditional sense. The process is less formal and you do not need a solicitor, though many applications carry a fee. A rent repayment order, for example, carries a flat application fee plus a separate hearing fee if the case is listed. Check the current amounts on GOV.UK, and apply for fee remission if you are on a low income.
For deposit disputes, the faster route is through your deposit protection scheme's free adjudication service. If your deposit is held in a government-approved scheme, you can apply for adjudication without going to tribunal. Adjudication decisions usually take 28 days.
For a disrepair claim seeking compensation, the usual route is a county court claim for damages under the Pre-Action Protocol for Housing Conditions Claims. This is more formal and worth getting advice on before you file. A Part 8 claim (the N208 form) fits a narrower case, such as asking the court to order works rather than damages. See the N208 form guide for tenants for where it applies.
A Rent Repayment Order can be worth a large sum. If your landlord has committed a relevant offence, including operating an unlicensed HMO, failing to comply with an improvement notice, or illegal eviction, you can apply to the First-tier Tribunal for an order requiring them to repay up to 2 years of rent (12 months for offences before 1 May 2026). The full guide to applying for a Rent Repayment Order covers eligibility and the application process in detail.
What counts as landlord harassment and what to do about it
Harassment is not a vague term in housing law. It has a specific legal definition under the Protection from Eviction Act 1977, and it covers a range of conduct that landlords sometimes think they can get away with.
Specific examples include: entering the property without notice or consent, repeatedly calling or messaging at unsociable hours, cutting off utilities, removing doors or windows, threatening the tenant verbally or in writing, and interfering with the tenant's quiet enjoyment of the property. All of these are unlawful. Some are criminal offences.
The most common context for harassment is retaliation after a tenant complains about repairs or conditions. A landlord who receives a complaint about damp and then starts showing up unannounced may be committing a criminal offence and exposing themselves to a civil claim.
If you are experiencing harassment, document every incident. Write down dates, times, and what happened. Screenshot messages. Keep a log. This evidence is what makes a council complaint or a court application viable.
Report harassment to your local council's private rented housing team. They can investigate, issue warnings, and refer cases for prosecution. In serious cases, the police can also be involved, particularly where there is a threat to personal safety or a criminal act such as illegal eviction.
Retaliatory eviction, where a landlord tries to evict you after a legitimate complaint, is now much harder. Section 21 'no-fault' evictions were abolished on 1 May 2026, so a landlord can no longer hand you a no-reason notice for complaining. A landlord must use a valid legal ground and prove it. If they use the moving-in or selling ground and then re-let or re-market the property within 12 months, the council can fine them up to £7,000, rising to £40,000 or prosecution for a repeat breach, and you can apply to the First-tier Tribunal for a rent repayment order of up to 2 years' rent. The landlord retaliation eviction guide explains how the protection works now.
How the Renters' Rights Act 2025 changes what tenants can claim
The Renters' Rights Act 2025 changes the enforcement picture in ways that matter to any tenant weighing a complaint right now.
Section 21 'no fault' evictions ended on 1 May 2026. Since that date, landlords must have a valid legal reason to evict. In practice, that means raising a complaint or making a formal claim no longer carries the same risk of a retaliatory notice two months later. The threat that kept many tenants silent has gone.
The Act also introduces new civil penalties for landlords who breach their obligations. These penalties range in scale, and the most serious violations attract fines of up to £40,000. Local councils are the enforcement authority for these penalties, which is why reporting to your council carries real weight. It now has direct financial consequences for non-compliant landlords.
Other changes relevant to tenants making complaints include: the requirement for landlords to join the new Private Rented Sector Ombudsman, the introduction of a Property Portal where landlords must register their properties, new rules on rent increases, where a landlord must use a formal Section 13 notice and a tenant can challenge it at the tribunal, and new rights on keeping pets.
The Property Portal and the Ombudsman scheme are still being rolled out, and are not yet live. Once they are, a landlord who fails to register a property or join the scheme will face enforcement for it, so this is worth watching rather than acting on today.
These Renters' Rights Act reforms, and the rent repayment order route, apply in England. Wales runs its own system under the Renting Homes (Wales) Act 2016, where renters hold occupation contracts. A landlord can still use a no-fault notice there under section 173, but must give at least 6 months.

How to build your evidence before making a formal complaint
The strength of your complaint depends almost entirely on your evidence. Councils, tribunals, and courts all make decisions based on what you can demonstrate, not on what you assert.
Start with photographs and video. Date-stamped photos of damp, mould, broken fittings, or unsafe conditions are straightforward to take and hard for a landlord to dismiss. Take them before any repair is attempted, and again if a repair is done inadequately.
Keep every message. Email threads, WhatsApp conversations, and text messages are all admissible evidence. If your landlord prefers phone calls, follow up each call with a written summary by email, such as "Following our call today, I am confirming that you said the repair would be done by Friday."
Get an independent record where possible. If you have reported mould to your GP because it has affected your health, ask for a record of that appointment. If a neighbour witnessed an incident of harassment, get a written statement. If a professional such as a plumber or electrician has seen the problem, ask for a written note of what they observed.
For deposit disputes, preserve all correspondence about the condition of the property. Your check-in inventory, your check-out report, and any photos taken at both ends of the tenancy are the core evidence. If your landlord did not provide an inventory at the start of your tenancy, that itself weakens their position in any deposit dispute.
If your landlord is ignoring repairs, harassing you, withholding your deposit, or threatening eviction, the route forward is the same: write it down, send it formally, escalate to the council if needed, and claim compensation if the law allows it. The process is more accessible than most tenants think, and the Renters' Rights Act 2025 has made it harder for landlords to avoid consequences.
If you are not sure where to start, Remedy can look at your situation, tell you what you can claim and what evidence you need, and help you draft the letters and organise it.
