Do I Need to Register with Rent Smart Wales?

The Short Answer

If you own a residential property in Wales that is rented out — or that you intend to rent out — you must register with Rent Smart Wales. No exceptions based on portfolio size, how long you have owned the property, or where you personally live.

This is a legal requirement under Part 1 of the Housing (Wales) Act 2014, enforced since 23 November 2016. It applies equally to a landlord with one terraced house in Swansea and an investor with forty flats in Cardiff.

Who Must Register

Registration is triggered by ownership, not by management activity. You must register if:

• You own a dwelling in Wales that is let under a standard occupation contract (the Welsh equivalent of what used to be an assured shorthold tenancy)
• You own a property in Wales that is being marketed for rent, even if no tenant has moved in yet
• You live in England, Scotland, Northern Ireland or overseas but own a rental property located in Wales
• You are a company, trust or charity that owns residential rental property in Wales
• You have inherited a tenanted property as an executor or beneficiary

The rule is straightforward: the property's location determines the obligation, not the landlord's address. A landlord living in London who owns a buy-to-let in Wrexham must register with Rent Smart Wales.

Who Is Exempt

A small number of arrangements fall outside the registration requirement:

• Resident landlords and lodgers — if you live in the same dwelling and rent a room to a lodger, that arrangement is not a domestic tenancy under the Act
• Holiday lets — properties let strictly as short-term holiday accommodation, not as someone's home
• Student halls — accommodation provided directly by a university or registered social landlord
• Social housing — properties owned by local authorities or registered social landlords
• Non-permanent structures — caravans, mobile homes and temporary buildings that are not permanent dwellings

If your arrangement does not clearly fit an exemption, register. The penalties for operating unregistered (Fixed Penalty Notices of up to £150, or prosecution with unlimited fines) far outweigh the £60 registration fee.

Registration vs Licensing — They Are Different

Registration records your identity as a property owner. It does not give you permission to manage the property.

If you carry out any letting or management tasks yourself — showing the property, collecting rent, arranging repairs, dealing with tenant queries, serving notices — you also need a separate Landlord Licence (£254 online). The only way to avoid the licence is to hand over every management task to a licensed letting agent.

Many first-time landlords register and then start self-managing without realising they need the licence too. That is an offence. A Welsh court can refuse to enforce a Section 173 notice if you are managing without a licence, and a contract-holder can apply for a Rent Repayment Order covering up to 12 months of rent for a licensing offence.

What Happens If You Do Not Register

The enforcement regime has real teeth:

• Fixed Penalty Notices — up to £150 for operating unregistered
• Criminal prosecution — unlimited fines on summary conviction in the Magistrates' Court
• Section 173 notices blocked — you cannot serve a valid no-fault notice while unregistered. Any Section 173 notice served while non-compliant is invalid
• Rent Repayment Orders — if you commit a licensing offence, the tribunal can order you to repay up to 12 months of rent to the contract-holder

RSW and local housing authorities actively enforce. They are not required to issue warnings before taking formal action.

How to Register

Registration takes 15–30 minutes online at rentsmart.gov.wales and costs £60. You will need your National Insurance number (or passport number), property addresses and — if applicable — your agent's RSW licence number. Online registration is confirmed instantly.
