FHL Tax Crackdown Fails to Refill Long-Term Rental Stock

The abolition of the Furnished Holiday Lettings (FHL) tax regime, which came into force in April 2025, was meant to level the playing field between short-term holiday rentals and mainstream residential lets, encouraging landlords to switch their properties back into the long-term rental pool. New evidence suggests it has done nothing of the sort. Rather than triggering a wave of conversions that might ease acute rental shortages in cities such as London, Manchester and Bristol, the policy appears to have simply squeezed landlord margins without materially shifting supply between the two markets.

This matters enormously for UK property investors because rental supply has become the defining constraint on the housing market. Zoopla's rental index has repeatedly shown demand outstripping available stock by a factor of two or three in many regional cities, with average UK rents up around 5-6% year-on-year even as wage growth cools. Policymakers had hoped that removing mortgage interest relief, capital allowances and CGT rollover relief for holiday-let owners would nudge a meaningful slice of the estimated 85,000-plus registered furnished holiday lets in England back into standard tenancies. The fact that this hasn't materialised suggests the government misjudged landlord behaviour: many holiday-let owners are treating the properties as lifestyle or leisure assets rather than pure yield plays, and are prepared to absorb reduced tax efficiency rather than commit to the Renters' Rights Act's tighter tenancy obligations.

The regional picture illustrates why. In tourist-heavy areas such as Cornwall, the Lake District, and parts of Scotland, holiday let density can exceed 15-20% of total housing stock in some postcodes, and local campaigners had pinned hopes on the tax change freeing up homes for permanent residents. Early data instead points to owners either accepting lower after-tax returns, restructuring ownership through limited companies, or exiting the sector entirely by selling rather than converting to long-term lets — a distinction with very different supply consequences. A sale to an owner-occupier removes a property from the rental market altogether, doing nothing to help tenants searching for a home to rent in Newcastle, Leeds or Liverpool, where affordability pressures are more acute among renters than second-home buyers.

For mainstream buy-to-let landlords, this is a moment of relative advantage tempered by continued regulatory uncertainty. Those holding conventional long-term rental portfolios in cities like Birmingham and Manchester, where rental yields still average 6-7% gross, face no additional disruption from the FHL changes but remain under pressure from Section 24 mortgage interest restrictions, EPC upgrade costs, and the incoming abolition of Section 21 evictions. Commercial and institutional investors — particularly those backing Build to Rent schemes — stand to benefit most, since the failure of tax policy to unlock secondhand stock strengthens the case for new-build purpose-built rental supply as the only reliable lever left to policymakers. Surrey and the wider South East, with strong Build to Rent pipelines and commuter demand, look increasingly attractive for institutional capital precisely because organic conversion of holiday lets has stalled.

First-time buyers are indirect losers here too. If former holiday lets are being sold rather than let, some additional stock does enter the sales market, theoretically helping buyers in coastal and rural hotspots. But this is scant compensation for renters who continue to face constrained choice and rising rents in undersupplied urban centres, where the FHL reform was never going to have much impact in the first place — holiday lets are heavily concentrated outside major cities. The mismatch between where the policy was aimed and where the rental crisis is most severe explains much of its apparent failure.

Looking ahead 6-12 months, expect the government to face growing pressure to pair fiscal disincentives with more direct planning interventions, such as mandatory use-class changes or local licensing caps on short-term lets, similar to schemes already trialled in Edinburgh and parts of Wales. Investors should treat the FHL episode as a case study in policy risk: tax changes alone rarely redirect capital between asset classes when the underlying yield and lifestyle incentives remain intact. Landlords currently weighing holiday-let exposure should model scenarios involving further licensing restrictions rather than assuming the tax change was a one-off adjustment, while long-term rental investors should recognise that supply relief is unlikely to come from this direction — reinforcing the strategic case for new-build rental development over hoped-for conversions.
