Landlord guide to letting in Cardiff

Why it matters

Failure to comply with Welsh housing legislation carries significant penalties, including fines, prosecution, and restrictions on your ability to manage property or serve valid notices. Unregistered or unlicensed landlords risk being unable to issue possession notices or having their contracts deemed invalid. Adhering to these regulations ensures legal compliance, protects your investment, and fosters a professional relationship with your contract-holders, avoiding costly disputes and enforcement action.

Legal requirements

• All landlords must register with Rent Smart Wales for each rental property they own in Cardiff.
• Any person or organisation carrying out letting or property management activities must hold a valid Rent Smart Wales licence and complete approved training.
• Landlords must provide a written statement of the occupation contract to the contract-holder within 14 days of occupation commencing.
• Properties must be fit for human habitation, as required by the 'Fitness for Habitation' legislation within the Renting Homes (Wales) Act 2016.
• Annual gas safety certificates must be obtained for all gas appliances and flues in the property.
• An Electrical Installation Condition Report (EICR) must be obtained and renewed at least every five years, or sooner if recommended.
• Working smoke alarms must be fitted on every storey and carbon monoxide alarms in any room with a fuel-burning appliance.
• Landlords must ensure the property has a valid Energy Performance Certificate (EPC) with a minimum E rating, unless exempt.
• Deposits must be protected in a Welsh-approved tenancy deposit scheme within 30 days of receipt.
• Any fees charged to contract-holders must comply with the Renting Homes (Fees etc.) (Wales) Act 2019.

Common mistakes

• Failing to register as a landlord with Rent Smart Wales, which is a mandatory requirement for all Welsh landlords.
• Not obtaining a Rent Smart Wales licence for yourself or your agent when undertaking letting or management activities.
• Using outdated tenancy agreements instead of the correct occupation contract written statements.
• Issuing possession notices incorrectly, such as without proper grounds or before fulfilling registration and licensing duties.
• Not ensuring the property meets the 'fit for human habitation' standard, leading to potential contract-holder claims.
• Failing to protect a contract-holder's deposit within the statutory timeframe or with a Welsh-approved scheme.
• Imposing prohibited fees on contract-holders, which can result in significant financial penalties.
• Neglecting regular maintenance and safety checks, like gas safety and electrical inspections.
• Not providing required safety certificates and the written occupation contract statement to contract-holders at the start of the contract.
• Overlooking specific HMO licensing requirements unique to Cardiff areas like Cathays and Roath.

Practical guidance

• Register yourself and your rental properties with Rent Smart Wales immediately if you have not already done so.
• If you manage your own property, complete the approved Rent Smart Wales landlord training and apply for your licence.
• If you use a letting agent, verify that they hold a valid Rent Smart Wales licence before instructing them.
• Engage a legal professional to draft or review your occupation contract written statements to ensure compliance.
• Arrange for all mandatory safety checks including gas safety, electrical, and smoke/carbon monoxide alarm installation before a new occupation begins.
• Obtain an EPC for your property and ensure it meets the minimum E rating, carrying out improvements if necessary.
• Familiarise yourself with the 'fit for human habitation' requirements under the Renting Homes (Wales) Act 2016.
• Upon receiving a deposit, protect it within 30 days with a scheme operating in Wales and issue the prescribed information.
• Regularly review Rent Smart Wales guidance and Welsh Government updates to stay informed of any legislative changes.
• If your property is a House in Multiple Occupation (HMO), check Cardiff Council's website for specific local licensing requirements.

Rent Smart Wales: The Gateway to Letting in Cardiff

The cornerstone of private rented sector regulation in Wales is Rent Smart Wales (RSW). Every landlord with property in Cardiff must register with RSW. This registration is distinct from holding a licence. Additionally, if a landlord undertakes any letting or property management activities themselves – including finding contract-holders, arranging contracts, collecting rent, or maintaining the property – they must also obtain a licence from RSW. This involves completing approved training to demonstrate an understanding of their legal obligations. If a landlord uses an agent, that agent must also be licensed by RSW. Failure to register or hold a licence can prevent a landlord from issuing a valid notice to end an occupation contract and carries potential fines or prosecution. Registration and licensing are vital initial steps for any landlord in Cardiff.

Occupation Contracts: The New Foundation of Tenancy in Wales

The Renting Homes (Wales) Act 2016 abolished assured shorthold tenancies and introduced a new framework based on 'occupation contracts' from December 2022. There are two main types: 'standard contracts' (replacing assured and assured shorthold tenancies) and 'supported standard contracts' (for social housing with support services). All new and existing tenancies automatically converted to occupation contracts. Landlords in Cardiff must provide a 'written statement' of the occupation contract to their contract-holder within 14 days of the occupation date. This statement outlines the terms, including 'key matters', 'fundamental terms' (which cannot be omitted or altered to the contract-holder's detriment), 'supplementary terms', and 'additional terms'. Understanding and correctly issuing these contracts is crucial for legal compliance and effective property management.

Housing Standards and Safety in Welsh Properties

Under the Renting Homes (Wales) Act 2016, all rented properties in Cardiff must be fit for human habitation. This includes requirements for smoke alarms on every storey, carbon monoxide alarms in rooms with fuel-burning appliances, and an Electrical Installation Condition Report (EICR) every five years. Gas safety checks remain an annual legal requirement. Properties must also have a valid Energy Performance Certificate (EPC) with a minimum E rating, unless exempt. These standards are designed to ensure contract-holders live in safe and healthy conditions. Non-compliance can lead to serious legal consequences, including enforcement action by Cardiff Council, fines, and claims from contract-holders for breach of contract, making diligent adherence essential for landlords.

HMO Regulations and Local Licensing in Cardiff

Cardiff, particularly areas like Cathays and Roath with dense student populations, has specific regulations for Houses in Multiple Occupation (HMOs). An HMO generally refers to a property rented by at least three people who are not from one 'household' but share facilities like bathrooms or kitchens. In Cardiff, mandatory HMO licensing applies to larger properties, typically those rented to five or more people forming more than one household. However, Cardiff Council has also implemented 'additional licensing' schemes which may cover smaller HMOs, such as those occupied by three or four people, in certain areas. Landlords of HMOs must check Cardiff Council's website for specific licensing designations and ensure their property complies with stricter management and safety standards, which can include minimum room sizes and fire safety provisions.

Differences Across the UK: A Brief Comparison

While this guide focuses on Cardiff and Welsh law, it is important for landlords with interests elsewhere to note key differences. In England, tenancies are primarily governed by the Housing Act 1988 (as amended) and Housing Act 2004, with the Renters' Rights Act 2025 having replaced assured shorthold tenancies with assured tenancies. Deposit protection and landlord registration schemes also differ. For example, England does not have an equivalent to Rent Smart Wales for all landlords, though some local authorities have selective licensing schemes. Scotland operates under the Private Housing (Tenancies) (Scotland) Act 2016, introducing Private Residential Tenancies. Northern Ireland has its own framework under the Private Tenancies Act (Northern Ireland) 2022, requiring landlord registration and deposit protection. Always consult specific regional guidance, such as our guides for /local/edinburgh, /local/london or /local/manchester, when dealing with properties outside Wales.
