Welsh Law Differences — Read This First
🏴 Wales Has Specific Housing Legislation
Renting Homes (Wales) Act 2016: Wales has its own housing legislation that came into full effect in December 2022. This Act replaced ASTs in Wales with Occupation Contracts — either Standard Occupation Contracts (equivalent to ASTs) or Secure Contracts (for social housing).
Written contracts required: All landlords in Wales must issue a written occupation contract within 14 days of occupation. Failure to do so means you cannot serve a no-fault notice to quit (equivalent to Section 21) and tenants can claim compensation. For more detail, see how Section 21 notices work.
No-fault eviction: The equivalent of Section 21 in Wales is the “no-fault notice to quit” requiring 6 months’ notice (compared to 2 months in England). This is significantly longer — factor this into your risk planning.
Fitness for Human Habitation: Wales has extensive FFHH obligations that go further than England’s equivalent — all properties must meet these standards throughout the occupation contract.
Landlord registration: All landlords (including R2R operators as sub-landlords) in Wales must register with Rent Smart Wales. You must also be licensed or use a licensed agent. This is mandatory and enforced.

Frequently Asked Questions
Do I need to register with Rent Smart Wales to do rent to rent in Cardiff?
Yes — registration with Rent Smart Wales is mandatory for all landlords (including rent to rent operators as sub-landlords) in Wales. You also need a Rent Smart Wales licence if you manage properties yourself, which as a rent to rent operator you do. Register at rentsmart.wales. Failure to register is a criminal offence in Wales and can result in a £2,500 fine for a first offence. Always complete registration before taking on your first Cardiff property.
Can I use an English tenancy agreement template for Cardiff properties?
No — since December 2022, Welsh tenancies operate under the Renting Homes (Wales) Act 2016 using Occupation Contracts, not Assured Shorthold Tenancies. English AST templates are not valid for Welsh tenancies. You must use Wales-specific Occupation Contract templates. The Welsh Government has published model written statements on gov.wales that provide a starting point. Always have a Welsh solicitor review your tenancy documentation before use. For more detail, see our rent-to-rent contract template.
