Business rates or council tax? The holiday let thresholds explained

Updated 27 September 2026. Every holiday let in Great Britain and Northern Ireland ends up on one of two lists. Either it is a business, valued for non-domestic rates, or it is a dwelling, liable for council tax (or domestic rates in Northern Ireland). Which list you are on can change your annual bill substantially, and since second-home premiums have climbed, landing on the wrong side has become expensive. This article compares the tests in each nation and explains how to stay on the side you intend.

The tests, nation by nation

• England: since 1 April 2023, a self-catering property is rated as a business only if, over the previous twelve months, it was available to let commercially for at least 140 nights and actually let for at least 70, and you intend to keep it available for 140 nights in the coming year.
• Wales: the bar is higher. The property must be available for at least 252 days and let for at least 182 days in the year. From 1 April 2026 an owner who misses the target once can rely on an average over two or three years, and a limited number of days donated to charities can count.
• Scotland: the property must not be anyone's only or main residence, must be let commercially with a view to profit, and must be available for 140 nights and let for 70 within the financial year.
• Northern Ireland: self-catering accommodation available for short-period letting for 140 days or more a year is generally valued for non-domestic rates by Land and Property Services; otherwise domestic rates apply.

What counts as a night, and what does not

The English guidance is the most explicit, and its logic is a sound guide everywhere. Nights you or your family use the property privately do not count, nor do discounted stays for friends. Periods closed for repairs or refurbishment are excluded. A booking longer than 28 nights cannot count as let nights, although the property can count as available if it was bookable for stays of 28 nights or less. Future bookings do not help: the assessment looks at what has happened, not what is in the diary.

Two consequences follow. First, a property used heavily by its owners in summer can fail the test even if it is let all winter. Second, a mid-term let to a contractor for two months helps your income but not your rates status. Plan the calendar with both in mind.

Who decides, and on what evidence

In England and Wales the Valuation Office Agency decides; English owners apply to its self-catering team by email. In Scotland it is the local assessor, and the evidence, typically listings, booking calendars and income records, must usually be sent by 26 May after the financial year closes. In Northern Ireland, Land and Property Services makes the call. In every case the burden is on you. An owner who cannot show the nights will be treated as a dwelling, whatever the reality was.

Timing matters when you start. Scottish Borders Council, for example, reminds new owners that a property stays in council tax until it has actually achieved its 70 nights, and only then should the owner apply; overpaid council tax is refunded if the change is backdated. Budget for council tax in the first year rather than assuming the switch is immediate.

Why the business side can be cheaper

Once rated as a business, a small holiday let may benefit from relief. In England, small business rate relief is 100% for a property with a rateable value of £12,000 or less, tapering to nothing at £15,000, and it is designed for businesses using one property; owners of several lets should check the rules on second properties. Scotland's Small Business Bonus Scheme applies to self-catering under combined rateable value limits. Wales and Northern Ireland have their own schemes. Relief is never automatic: apply to the council that sends the bill.

Why the dwelling side has become costly

On the council tax side, second homes attract premiums. In England councils have been able to charge up to twice the normal bill since April 2025. In Wales the ceiling is 300%, set council by council. In Scotland the cap was removed in April 2026, and several councils now charge well above double. A holiday let that slips below the threshold can therefore move from a modest or zero rates bill to a council tax bill several times the standard figure. Our separate article on second-home premiums goes through the details.

Common traps

• Counting nights from platform payouts instead of the calendar: cancellations and refunds can inflate the figure.
• Blocking the calendar for months of works without keeping invoices that explain the closure.
• Assuming that a property on the valuation list stays there: it can be moved back to council tax if it stops meeting the criteria.
• Forgetting that in Wales the thresholds are much higher, so a model that works in Devon may fail in Pembrokeshire.

A record-keeping routine that works

Keep one master calendar showing, for each night, whether the property was bookable, booked, blocked for the owner or closed for works. Export it monthly with the matching platform reports and invoices. At year end, total the available and let nights, compare them to the threshold for your nation and file the evidence on time. The same file will serve for income tax and for any registration scheme that asks how the property is used.

How we approach it

When an owner asks us to look at a holiday let, one of our first calculations is whether the threshold is realistic given the owner's own use, the seasons and the location. Sometimes the right answer is to reduce personal stays; sometimes it is to accept council tax and plan for it. Tell us about your property; we study every request and tell you honestly whether and how we can help.
