The 2025 UK Budget has brought significant changes for landlords and property owners and while some of the harsher speculations didn’t become law, the impact on rental income and property yields remains substantial. At Kapital Real Estate, we’re closely monitoring these developments so we can guide landlords and investors through the shifting landscape.
What Changed (and What Didn’t)
What Landlords Should Know
-
The previous rumours that rental income will now be subject to National Insurance (NI) have not materialised – rental income remains outside NI.
-
However, from April 2027 rental (property) income tax rates will rise by 2 percentage points. This means: basic-rate taxpayers will pay 22%, higher-rate 42%, and additional-rate 47% on property income.
-
For owners of high-value homes, a new annual surcharge – often dubbed the “mansion tax” – will apply from April 2028 for properties valued over £2 million.
What Landlords Should Reconsider
-
Because of the higher tax on property income starting in 2027, net rental yields may fall – affecting profitability, particularly for landlords with lower rental margins.
-
The surcharge on high-value properties adds a recurring cost for landlords of premium homes, further reducing net returns for investors holding such assets over the long term.
-
The combination of rising costs and regulatory changes may influence landlords’ decisions around pricing, portfolio growth, or even exiting the market.
What It Means for Your Portfolio — Key Considerations
-
Revisit Cash Flow Projections: If you haven’t recently reviewed your rental yield vs. costs, now is the time. The tax rise will likely impact net returns, especially for landlords already working with tight margins.
-
Portfolio Strategy & Risk Evaluation: For landlords with high-value holdings or multiple properties, it may no longer make sense to hold certain units – particularly if yields drop below acceptable levels.
-
Rent & Tenancy Planning: Some landlords may feel pressured to increase rents to offset increased tax burdens. However, doing so may risk tenant retention – and possibly clash with evolving rental regulations.
-
Long-Term Investment Strategy: These changes may shift the attractiveness of buy-to-let investing, prompting consideration of alternatives such as incorporation, selling, or repurposing assets.
