Short-Term Let Rules in Cardiff & Newport: Similarities vs Differences

Cardiff and Newport remain two of the most attractive cities in south Wales for short-term letting, but the regulatory landscape is shifting fast. If you own property in either city and want to let it to domestic and international guests on a short-term basis, you need to understand exactly what is required of you right now and what is coming next.

Fast overview: Can you still run a holiday let in Cardiff and Newport?

Yes, short-term and holiday lets are still legal in both Cardiff and Newport in 2026. There is no ban. However, tighter rules on licensing, planning permission and council tax mean that many owners who operated informally in the past will need to formalise their arrangements or face penalties.

Here is the basic position in each city:

• Permission and licensing: Both cities fall under the Welsh national statutory registration scheme for visitor accommodation. All short-term accommodation providers in Wales must register with the Welsh Revenue Authority by March 31, 2027. Local enforcement is handled by the respective council.
• Council tax vs business rates: Whether your property pays council tax or non-domestic business rates depends on how often it is available and actually let. Properties that do not meet minimum letting thresholds stay on council tax, potentially with a second home premium of up to 300%.
• Enforcement: Both Cardiff Council and Newport City Council are becoming more proactive in monitoring holiday lets, investigating noise complaints and checking safety compliance.

Short-term rentals in Cardiff and Newport are governed by Welsh national legislation, but each council also applies its own local policies. Property owners must check both levels before listing.

Pass the Keys can help Cardiff and Newport hosts navigate compliance, guest communication and pricing strategy, so you stay on the right side of the rules while earning rental income.

National Welsh framework for short-term and holiday lets (applies to both cities)

Many of the rules affecting holiday home owners in Cardiff and Newport start at Welsh Government level and are then enforced locally by each council.

Key national measures that apply to both cities:

• Statutory licensing: The Development of Tourism and Regulation of Visitor Accommodation (Wales) Act 2026 creates a national licensing scheme for visitor accommodation including holiday lets, self-catering properties and serviced apartments. Registration opens in October 2026 with a deadline of 31 March 2027.
• Planning use classes: The Welsh Government introduced planning framework changes establishing distinct property use classes. Class C3 covers sole or main residences, C5 covers non-primary dwellings, and Class C6 is designated for short-term holiday lets in Wales - entire dwellings used commercially for stays of up to 31 nights.
• Council tax premium powers: From 1 April 2023, Welsh councils gained the power to charge council tax premiums of up to 300% on second homes and long-term empty properties. These premiums now apply across Wales.
• Safety and record keeping: National requirements for gas safety, electrical inspections, fire safety and guest records are being codified through the licensing scheme.

Even where exact start dates for certain provisions may shift, owners should assume that registration, licensing and higher council tax on non-primary holiday homes will be the norm going forward.

Licensing and registration of short-term lets in Cardiff

Cardiff is expected to require all short-term holiday lets to be registered under the Welsh national scheme, with local enforcement carried out by Cardiff Council. If you operate an Airbnb or short-term let in Cardiff, preparation should begin now.

A short-term let typically means accepting guests for stays of under 31 days via platforms like Airbnb, Booking.com and other biggest holiday letting platforms.

A Cardiff licence or registration is likely to require:

• Owner or responsible person details (name, address, contact)
• Property details: address, layout, maximum occupancy
• Safety certificates: gas safety, EICR electrical report, fire safety documentation
• Proof of appropriate insurance (public liability and property)

Operating a holiday let without the necessary licence or registration may lead to fines, orders to stop accepting guests, and difficulties with insurance and mortgage compliance.

Local authorities in Wales can also implement a visitor levy for short-term lets. Cardiff plans to implement a visitor levy of approximately £1.30 per person per night starting in April 2027, adding a further cost that hosts will need to factor into their pricing.

Licensing and registration of short-term lets in Newport

Newport falls under the same Welsh national schemes as Cardiff, but processes and day-to-day enforcement are handled by Newport City Council rather than Cardiff.

When you register a holiday home or short-term let in Newport, the council is likely to ask for:

• Full address and proof of ownership or permission to let
• Property layout and maximum occupancy
• Proof of safety checks (gas, electrical, fire) and emergency contact details
• Insurance documentation

Newport can refuse or revoke registration where properties cause persistent issues such as noise complaints, antisocial behaviour, overcrowding or safety breaches. This is consistent with the national framework but enforced at city level.

Licensed or correctly registered short term rental properties are also easier to list on major platforms, as these sites increasingly ask hosts to confirm regulatory compliance before publishing listings.

Planning permission: when a Cardiff or Newport holiday let becomes a 'material change of use'

Planning rules decide whether your property can legally be used as a holiday let at all, separate from any licensing requirement. This is an area where Welsh planning policy is evolving quickly.

Planning permission might be required when converting a residential property to a short-term let, depending on local policies. Key points:

• Using a main home for occasional short letting may not need formal planning consent, but turning an entire dwelling into a full-time holiday home usually triggers a material change of use from C3 to C6.
• Both Cardiff and Newport can treat high-intensity short-term letting as a change of use, especially in neighbourhoods where housing pressure is acute.
• Welsh councils may use Article 4 Directions to control changes between main homes and short-term lets, removing permitted development rights so that any switch requires planning consent.
• Cardiff currently does not have a blanket Article 4 restriction requiring planning permission for all short-term lets, but this could change as the council reviews its Local Development Plan.

If you are converting a long-term rental or buying a new property as a dedicated holiday let, seek pre-application guidance from the relevant council before you list.

Council tax, premiums and business rates for Cardiff and Newport holiday homes

Both cities can charge council tax premiums on second homes and long-term empty properties under powers strengthened in April 2023. Understanding how council tax interacts with holiday letting is essential to protecting your rental earnings.

Here is how the system works:

To qualify for non-domestic business rates, the property must be available for letting for at least 252 days in a given year and actually let for at least 182 days per year. If you fall short, the property reverts to domestic council tax with a potential premium.

• Cardiff set its second home premium at 100% from 1 April 2024, with a similar 100% premium on long-term empties.
• Newport applies a 100% council tax premium on second homes starting from April 2025.
• Council tax premiums of up to 300% can be charged on second homes and unqualifying short-term lets in Wales, though neither Cardiff nor Newport has yet gone to the maximum.

Owners should budget for higher council tax on non-primary holiday homes and keep meticulous records of let days and availability to challenge any errors or apply for valid exceptions.

Safety, compliance and guest screening duties

Safety compliance is the most important part of running a legal and reputable holiday let in both cities. Compliance with local regulations helps avoid costly mistakes, reputational damage and potential liability.

Core legal duties common to Cardiff and Newport:

• Annual gas safety checks by a Gas Safe registered engineer
• EICR electrical safety inspections at required intervals (typically every five years)
• Mains-linked smoke alarms on every floor
• Carbon monoxide detectors where solid fuel appliances or gas boilers are present
• Clearly marked escape routes and fire safety documentation

Hosts must also comply with safety regulations including gas safety checks and electrical safety inspections as part of the forthcoming national licensing conditions.

Additional expectations cover guest screening and guest safety: recording lead guest details, setting maximum occupancy limits, applying age restrictions where relevant, and providing clear house rules to prevent nuisance to local communities. Regulatory compliance is crucial for operating a holiday let, and Pass the Keys can coordinate inspections, certificates and guest screening processes so that property owners meet local standards and platform requirements.

Operating standards: bookings, check-in/check-out and guest communication

While not all operating standards are legal requirements, councils and platforms expect professional handling of bookings and guests. Management services that ensure prompt responses to guest inquiries tend to generate more bookings and better reviews over time.

Best practice for check-in and check out in city-centre flats and terraced streets:

• Use key safes or smart locks to enable flexible, contactless arrival
• Set quiet hours and enforce them through house rules
• Provide clear rubbish, recycling and parking instructions to keep neighbours on side
• Include local recommendations in a digital guest guide

Responsive guest communication before arrival, during the stay and after check out prevents complaints from escalating to the council. Booking management systems also prevent double bookings and miscommunication, which can damage your property's reputation and guest satisfaction.

Automated messaging and a digital guest guide can streamline information sharing for potential guests, handling booking requests and guest queries without making everyday life a full time job.

Income, dynamic pricing and seasonality in Cardiff and Newport

Regulations shape what you can do, but pricing strategy and occupancy rates determine whether a holiday let produces a profitable revenue stream or just breaks even.

Seasonal patterns differ between the two cities:

• Cardiff: International rugby at Principality Stadium, concerts, university term times and major conferences drive sharp demand spikes. Cardiff is a popular destination for both domestic and international travel, making it more than one of the more traditional holiday destinations in Wales.
• Newport: ICC Wales conferences, sporting events and spillover demand from Cardiff and Bristol create periodic peaks. Newport may not match traditional holiday destinations for baseline tourism, but its ideal location on the M4 corridor and proximity to the Brecon Beacons creates steady market demand.

Dynamic pricing tools adjust nightly rates to demand, local events and lead time. Variable pricing models help maximize bookings and profits by lifting rates during sold-out weekends and lowering them to maintain occupancy during quieter mid-week periods. Holiday let management companies can help optimize pricing strategies so that owners maximise income across various sites and the rental market stays competitive.

Pass the Keys uses data-driven pricing adjustments across the biggest holiday letting platforms, so Cardiff and Newport owners do not need to monitor each event or upcoming bookings manually.

Choosing self-management vs a professional manager in Cardiff and Newport

Running a short term accommodation property yourself gives you complete control, but in a tightening regulatory environment it can quickly become a demanding task and a time consuming one. The choice between DIY and using a holiday let management company depends on your appetite for admin, your in depth knowledge of local regulations and your available time.

Self-managing owners are responsible for:

• Licensing registration and council communication
• Guest communication, managing bookings and own bookings on their own website
• Cleaning, linen and property maintenance
• Council tax or business rates submissions
• Remaining compliant with safety and planning rules

A fully managed service typically covers:

• Listing creation with professional photography on major platforms (some providers like StayCotswold use professional photography to enhance property listings; Host & Stay lists properties on over 60 online travel agencies; Sykes has relationships with over 700 booking partners and spends £35 million annually on marketing)
• Revenue management and dynamic pricing (Sykes, for example, offers a revenue management system using real market data)
• Guest vetting, 24/7 guest support, and holiday let agencies handle all guest communication efficiently
• Cleaning after every check out and maintenance coordination

Management companies typically charge 15% to 30% commission, and regular monthly payments and detailed financial statements are standard. Using a management company can save owners significant time and effort, though owners may lose some control over property management decisions.

In cities with tightening short-term let rules such as Cardiff and Newport, professional support from a management agency reduces the risk of accidental non-compliance and frees up owner time for everyday life or managing multiple properties elsewhere.
