How to Complain About Your Landlord UK: Full Guide

Before you involve anyone else, put your complaint in writing. This is not just good manners. It creates a timestamped record that every subsequent authority, from your local council to a tribunal, will want to see.

Send an email or letter that does three things: describes the problem specifically, states what you want done about it, and sets a clear deadline. Ten to fourteen days is reasonable for most repair issues. Something like: "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: "Following our conversation on Tuesday, I am confirming that I raised the following issue."

Shelter England recommends this approach and provides template letters for tenants who are not sure where to start (Shelter England, 2026). Templates matter 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.

Remedy Legal can help you draft that initial letter, pulling in the relevant legislation automatically based on the details of your situation. The AI-drafted letter feature references the applicable law so the complaint lands with the right weight.

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 12 months' rent.

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 2026, councils received additional enforcement tools and the authority to issue civil penalty notices up to £40,000 for the most serious landlord breaches (GOV.UK, 2026). 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.

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 2026 requires private landlords to join a new Private Rented Sector Ombudsman scheme. This is a significant shift. 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 (Housing Ombudsman, 2026).

For private renters whose landlords are not yet in the new scheme, the council remains the more direct route for enforcement. But keep checking. The Private Rented Sector Landlord Ombudsman guide explains how the new scheme works and what you can claim through it.

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.

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.

Remedy Legal's AI-drafted letter feature generates letters that reference the applicable legislation based on your specific situation, which means you do not need to know the statutory citation off the top of your head. The free tier gives you an instant assessment of your situation and clear next steps before you commit to anything.

For a step-by-step guide on writing the letter yourself, see how to write a letter before action to your landlord.

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 rent increases under Section 13, and disputes about property conditions. It is not a court in the traditional sense. The process is less formal, you do not need a solicitor, and there is no fee for most applications.

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 disrepair claims where you are seeking compensation, you may need to go through the county court using the N208 form for Part 8 claims. This is more formal and worth getting advice on before you file. See the N208 form guide for tenants for the process.

Rent Repayment Orders are one of the most financially significant routes available to tenants. 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 12 months of rent. The full guide to applying for a Rent Repayment Order covers eligibility and the application process in detail.

Remedy Legal's tribunal support feature helps you prepare your tribunal bundle, track deadlines, upload and annotate evidence, and understand what to expect on the day. A paid platform tier is available which covers these support services.

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 (Lawhive, 2025).

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 is not just being difficult. They are potentially 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.

Retaliation eviction, where a landlord tries to evict you after you have made a legitimate complaint about the property, is specifically restricted under the Deregulation Act 2015. If your landlord serves a Section 21 notice within six months of a council complaint or an improvement notice, the notice is invalid. The landlord retaliation eviction guide explains exactly how this protection works.

The Renters' Rights Act changes the enforcement picture in ways that matter to anyone thinking about how to complain about their landlord in the UK right now.

Section 21 'no fault' evictions are ending on 1 May 2026. From that date, landlords must have a valid legal reason to evict. This is not a minor procedural change. It means that raising a complaint or making a formal claim against your landlord no longer carries the same risk of receiving a retaliatory notice two months later. The threat that kept many tenants silent is being removed.

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 (GOV.UK, 2026). Local councils are the enforcement authority for these penalties, which is why reporting to your council is not just symbolic. 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 that require a formal Section 13 notice and allow tenants to challenge increases at tribunal, and new rights on keeping pets.

If your landlord is not registered on the Property Portal, or has not joined the Ombudsman scheme, that itself becomes a ground for a complaint and potentially a fine. These administrative failures are no longer just technical issues. They are enforceable.

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 just 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: "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.

Remedy Legal's platform tier includes document storage and deadline tracking, so you can keep everything in one place rather than hunting through inboxes when you need it. The Landlord and Property Assessment feature also checks your landlord's compliance status, including deposit protection, gas safety certificates, and HMO licensing, which can surface violations you were not aware of.
