If you own rental property in Cardiff — whether it is a terraced house in Cathays, a flat in Roath, or a bedsit in Adamsdown — you are operating in one of the most regulated private rented sectors in the United Kingdom. Wales has forged its own distinct legislative path, and as of August 2026, the obligations placed on Cardiff landlords under the Renting Homes (Wales) Act 2016 are more firmly embedded than ever.
This is not a moment to sit back. This is a moment to act.
At Belvoir Cardiff, we work with landlords across the city every single day, helping them stay compliant, protect their investments, and build positive relationships with their contract holders. This guide cuts through the complexity and gives you a clear, practical picture of where you stand right now.
Understanding the Renting Homes (Wales) Act 2016 — a quick recap
The Renting Homes (Wales) Act 2016 came fully into force in December 2022, replacing the previous framework of assured shorthold tenancies with a new system of occupation contracts. It fundamentally changed the language and legal structure of renting in Wales.
Under this legislation, the people living in your property are no longer referred to as tenants. They are contract holders. This is not merely a terminology update — it reflects a substantive shift in the rights and protections afforded to occupiers across Wales.
For Cardiff landlords managing properties in high-density rental areas such as CF24 — which covers Cathays, Roath, and Adamsdown — understanding these obligations is critical. These postcodes are home to a large student and young professional population, and demand for well-managed, compliant rental accommodation continues to grow.
Written statements: are yours up to date?
One of the most fundamental requirements under the Renting Homes (Wales) Act is the issuing of a written statement of the occupation contract to every contract holder.
What must a written statement include?
Your written statement must set out all the key terms of the occupation contract, including the fundamental terms prescribed by Welsh Government, supplementary terms, and any additional or modified terms you have agreed. It must be issued within 14 days of the occupation date.
Failure to provide a written statement on time can result in financial penalties. A contract holder can apply to the court, and you may be ordered to pay up to two months’ rent in compensation.
If you have not reviewed your written statements since the Act came into force, or if you have taken on new contract holders recently, now is the time to ensure your documentation is fully compliant. Belvoir Cardiff can assist you in reviewing and issuing the correct documentation.
Fitness for human habitation — your ongoing duty
The Fitness for Human Habitation (FFHH) requirement is one of the most significant ongoing obligations for Cardiff landlords. It is a fundamental term of every occupation contract, meaning it cannot be excluded or modified.
What does FFHH require?
You must ensure that your property is fit for human habitation at the start of the contract and throughout its duration. This covers a broad range of factors, including structural stability, freedom from damp and mould, adequate heating, safe electrical installations, and working smoke and carbon monoxide alarms.
In older terraced properties common in Adamsdown and parts of Roath, issues such as damp penetration, outdated wiring, and inadequate ventilation are not uncommon. If a contract holder reports a hazard and you fail to act, they have the right to apply to the court for a remedy — and you could face significant legal and financial consequences.
Practical steps for Cardiff landlords
Carry out regular property inspections and keep detailed records. Address maintenance issues promptly and document all communications with contract holders. Ensure your electrical installation condition reports (EICRs) and gas safety certificates are current.
Properties in Cathays, which houses a large proportion of Cardiff’s student population near Cardiff University, are particularly high-turnover environments. Staying on top of FFHH compliance between occupancies is essential.
No-fault eviction under Welsh law — what landlords must know
This is an area where Welsh law differs significantly from the position in England. Under the Renting Homes (Wales) Act, landlords wishing to end a standard occupation contract without fault must issue a no-fault notice — but the notice period is six months, not two.
Furthermore, you cannot issue a no-fault notice within the first six months of an occupation contract. This means contract holders in Cardiff have greater security of tenure than their counterparts in England.
If you are considering regaining possession of a property in Cardiff — perhaps to sell, refurbish, or redevelop — you must factor these extended notice periods into your planning. Belvoir Cardiff regularly advises landlords on possession timelines and ensures all notices are served correctly and lawfully.
Rent Smart Wales: your licensing obligations in 2026
Rent Smart Wales remains a cornerstone of the Welsh private rented sector regulatory framework. As a landlord in Cardiff, you must be registered with Rent Smart Wales. If you self-manage your property, you must also hold a valid licence.
If you use a licensed letting agent such as Belvoir Cardiff, your agent’s licence covers the management activities — but your registration as a landlord remains your personal responsibility.
Licences are valid for five years. If yours is approaching renewal, do not leave it until the last minute. Operating without a valid licence is a criminal offence in Wales, and Cardiff Council has powers to prosecute non-compliant landlords.
Making Tax Digital — the 7 August 2026 deadline landlords cannot ignore
Alongside your obligations under the Renting Homes (Wales) Act, Cardiff landlords with property income need to be aware of Making Tax Digital (MTD) for Income Tax Self Assessment.
From 6 April 2026, landlords with qualifying income over £50,000 from property and self-employment are required to use Making Tax Digital for Income Tax, including keeping digital records and submitting quarterly updates to HMRC through compatible software. The deadline for the first quarterly update is 7 August 2026.
If you are a portfolio landlord managing multiple properties across Cardiff — perhaps a mix of student HMOs in Cathays and family lets in Roath — the administrative implications are considerable. Getting your record-keeping systems in order now will prevent a very stressful transition later in the year.
Speak to your accountant and ensure your letting agent is providing you with the documentation you need to meet your MTD obligations.
Why Cardiff’s rental market makes compliance more important than ever
Cardiff’s private rented sector is one of the most active in Wales. The city’s population has grown steadily, driven by its universities, the expanding Cardiff Bay regeneration zone, and a thriving professional community centred around the city centre and Canton.
According to data from the Office for National Statistics and Rent Smart Wales, Cardiff accounts for a significant proportion of all registered landlords in Wales. Average rents in Cardiff have risen year on year, with CF24 postcodes consistently among the most in-demand for both students and young professionals.
With demand high and supply tight, contract holders are increasingly aware of their rights. A well-managed, compliant property in Roath or Adamsdown will attract and retain good contract holders — protecting your rental income and your investment.
