Recent changes to Welsh housing policy have placed a heavy financial burden on owners of self-catering cottages. The legislation, introduced three years ago, classifies any property that is not let for at least 182 days a year as a second home and applies a council-tax premium that can reach 75 %. For small operators who rely on holiday rentals for their livelihood, the new regime threatens to erase years of investment.
While Wales tightens its rules, parts of England continue to allow holiday let owners to sidestep the higher rates by registering their properties as small businesses. The same divergence appears in Ireland, where a new analysis suggests that converting short-term lets back to long-term housing could accommodate tens of thousands of residents.
Welsh tax reforms and their impact on small holiday lets
Paul Martin, who runs four cottages at The Forest Country House near Newtown, Powys, says the 182-day requirement is unsustainable. Two of his cottages are officially restricted to holiday use, but because they sit adjacent to his family home they cannot be sold as separate residences. Under the new rules, Martin faces five separate council-tax bills this year, two of which carry the 75 % premium.
“This legislation will destroy me,” Martin told reporters, adding that retirement would leave him with no viable way to meet the costs. He invested his savings and borrowed funds to convert dilapidated outbuildings into lettable cottages, only to find the tax burden making the business “unsellable”.
Liz Molyneux, another Powys resident, pays a premium of more than £4,000 on an annex attached to her home. The annex was originally built for in-laws, later used as a holiday let, and now serves both as part of her household and a rental unit. “It shares electricity, water and oil with my main house – it is not a separate second home,” she insists.
The Welsh government argues that many operators are exempt if their properties carry a usage restriction, and from April 2027 new transfers will receive a year at the standard rate before any premium applies. Nevertheless, the council retains discretion to grant hardship exemptions, and Powys Council is currently reviewing back-dated premium bills.
England’s small-business rates relief: a tax loophole
In England, owners of holiday homes can avoid the hefty council-tax premium by registering the property as a small business. The criteria require the accommodation to be offered to holidaymakers for at least 140 days a year and actually let for a minimum of 70 days. When a property meets these thresholds, it qualifies for Small Business Rates Relief (SBRR), which can reduce the rate to zero.
At the recent Budget, Chancellor John Healey chose not to close the loophole, despite a Treasury consultation that had flagged possible abuse. Instead, the threshold for full relief was raised from £12,000 to £18,000 of annual revenue for retail, hospitality and leisure premises, a move that largely leaves holiday let owners unaffected because most already pay nothing.
Data from the Valuation Office Agency shows 79,550 short-term let properties in England and Wales are registered for business rates, an increase from 75,860 the previous year. Only about 1.5 % of these owners pay any portion of the rate, underscoring how effective the relief has become.
Industry groups such as the Professional Association of Self-Caterers (PASC UK) welcomed the decision, arguing that genuine holiday-let businesses provide essential income for cleaners, tradespeople and local shops. Critics, however, claim the system lets investors flip properties from council tax to business rates, paying little or no tax while contributing to housing shortages.
Irish study shows short-term lets could add thousands of homes
An independent analysis commissioned by the Irish Housing Agency reveals that short-term lets in high-demand areas could be converted into long-term housing for nearly 50,000 people. The consultancy Indecon identified 28,342 short-term lets across the country, with 32 % located in Dublin and 87 % in regions where housing demand is acute.
Of those, 16,870 are classified as commercial-tourism lets. If each were repurposed for permanent residence, they could shelter 46,224 individuals. The report outlines several scenarios, suggesting that even a modest regulatory approach could return between 3,100 and 9,500 units to the housing stock.
The Irish government plans to regulate short-term lets through the Short-Term Letting and Tourism Bill 2026, which will introduce a national register for properties let for up to 21 consecutive nights and impose restrictions in 25 towns with populations over 20,000.
While the Irish case differs in legal context, the pattern mirrors the Welsh and English debates: the balance between tourism-driven income and the preservation of affordable, long-term housing remains a contentious policy frontier across the UK and Ireland.
Stakeholders on all sides agree that clear definitions—what constitutes a “second home” versus a “genuine holiday let”—are essential. Without precise criteria, operators risk insolvency while communities risk losing the very homes they need.
