Holiday Let Rules in Wales 2026: What Owners Need to Know

Wales runs its own rulebook for holiday lets, separate from England, and 2026 is the biggest year of change owners have faced. A national registration scheme opens on 1 October 2026, the 182 day rule decides whether you pay business rates or council tax, second home premiums are biting across North Wales, and a visitor levy is on the way in some counties.

This guide explains each rule in plain English and what to do before the deadlines, whether your property is in Llandudno, on Anglesey or anywhere in between.

Registration opens on 1 October 2026

From 1 October 2026, anyone who takes bookings for overnight visitor stays in Wales must register with the Welsh Revenue Authority. The requirement covers stays of 31 nights or fewer, and it applies to everyone: whole cottages, apartments, a spare room, a property let for one week a year or for all fifty two.

Registration is free and takes most people under fifteen minutes. You will be asked for your contact details, the property address, the type of accommodation, how many guests it sleeps and when it is typically available for bookings. Parts of the register will be public, so guests and councils can check that a property is properly registered.

If we manage your property, the registration admin is handled as part of the service. If you self manage, put a reminder in your calendar for the first week of October, and work through our free Welsh holiday let registration checklist so the details are ready before the scheme opens.

The 182 day rule decides what tax you pay

To qualify for business rates rather than council tax, a Welsh holiday let must be available to let for at least 252 nights a year and actually let for at least 182. The Welsh thresholds are higher than England’s, so owners with properties on both sides of the border are often caught out.

Clearing the bar matters more in Wales than anywhere else, because falling short does not just mean paying ordinary council tax. If the property counts as a second home, most North Wales councils add a premium on top, and the difference between the two outcomes can run to thousands of pounds a year.

Hitting 182 let nights is a pricing and marketing job: professional rates that follow demand, presence on the right booking channels, and records that prove every night. It is the single strongest argument for managing a Welsh holiday let properly rather than letting it tick over.

Council tax premiums across North Wales

Conwy county charges a 150% premium on second homes, a rate it has confirmed it is keeping for 2026/27 and 2027/28. Long term empty homes there pay a 200% premium, rising to 300% once a home has stood empty for five years or more. Other North Wales counties set their own premiums each year.

The sums are stark. A premium can more than double an ordinary council tax bill, while a property that qualifies as a genuine holiday let business under the 182 day rule moves onto business rates instead, and many smaller properties then qualify for small business rates relief. How the property is run is what separates the two outcomes.

The visitor levy is coming, but not to the north yet

The Senedd has passed a law letting each Welsh council add a small nightly charge to visitor stays. The earliest any council can start is April 2027, and the proposed charge for most self catering stays is £1.30 a night per person, with a lower 75p rate for hostels and campsites.

Cardiff has confirmed a levy from 1 April 2027. In the north, nothing is decided: Gwynedd consulted over the summer and its full council votes on 24 September 2026, Conwy is consulting, and no North Wales council has set a start date. If a levy does arrive, collecting it and paying it over will sit with whoever manages your bookings, which is one more job professional management absorbs.

Letting long term instead? That is a different regime

Long term lettings in Wales run under the Renting Homes (Wales) Act 2016. Tenants hold occupation contracts rather than the tenancies used in England, landlords must register with Rent Smart Wales, and whoever manages the tenancy needs a Rent Smart Wales licence. England’s Renters’ Rights Act does not apply in Wales, so advice written for English landlords is often wrong here.

Holiday lets sit outside Rent Smart Wales, which is one reason many North Wales owners choose short stays. If you are weighing the two for your property, talk it through with someone who knows both regimes.

Planning in Gwynedd is still unsettled

Gwynedd brought in an Article 4 direction in September 2024, which meant planning permission was needed to change a main home into a holiday let across most of the county. The High Court quashed the direction, and the council is appealing. Until the courts settle it, check the current position before converting a property in Gwynedd, and take advice on anything you are buying specifically to let.

What to do before 1 October

• Download the registration checklist and gather the details it lists.
• Diarise the first week of October to register with the Welsh Revenue Authority. It is free.
• Check your let nights against the 182 day rule and price the autumn to close any gap.
• If the property is billed as a second home, find out your county’s premium and what business rates would cost instead.
• Keep a record of every let night. Those records are your evidence.
• Watch the levy decisions in Gwynedd and Conwy this autumn.
