The Chancellor’s Autumn Budget has landed, and its impact on the private rented sector is already sparking serious concern. The centrepiece for landlords is clear: a 2% increase in tax on property (rental) income, coming into effect from April 2027.
While this may initially appear modest, it comes at a time when landlord profitability has already been eroded by years of legislative and financial pressure. When placed in context — tighter regulation, higher borrowing costs, and the erosion of mortgage-interest relief — this Budget could become the tipping point that reshapes the rental landscape.
Below we explain why rents are likely to rise, why many landlords will now consider selling, and what this means for renters and the wider housing market.
What’s Changing — and Why It Matters
The Budget confirmed a 2 percentage-point rise in the tax rate applied to rental income. That means:
-
22% basic-rate tax
-
42% higher-rate tax
-
47% additional-rate tax
For landlords whose margins are already tight — especially those with mortgages — even small shifts in net income have a significant impact.
This increase arrives alongside:
-
Reduced mortgage-interest tax relief over recent years
-
Higher financing costs following long-term interest rate rises
-
Increasing compliance obligations through legislation such as the Renters’ Rights Act
-
A slow but persistent rise in operational and maintenance costs
In combination, the new tax burden is not just another addition — it compounds existing pressures.
Why Rents Are Likely to Rise
1. Shrinking Profit Margins Mean Costs Get Passed On
Most landlords operate their portfolios as small businesses. When taxation rises and margins fall, landlords have two options:
-
Absorb the reduction in profit
-
Adjust rental prices to compensate
Given the already tight margins many face — particularly mortgaged landlords — rent increases are the most likely outcome.
2. Reduced Rental Supply Will Push Prices Up
When profitability falls below acceptable levels, landlords begin to exit the market.
A reduced number of rental properties means that housing supply shrinks while tenant demand remains constant or increases.
Basic economic reality follows: fewer available properties = higher rents.
3. Additional Costs Amplify the Effect
Landlords are facing more than just taxation:
-
Higher insurance premiums
-
Stricter compliance requirements
-
Potential upgrades needed to meet new regulation
-
Greater maintenance expectations from tenants and councils
These mounting costs make raising rents not just attractive, but in many cases essential for a landlord to remain solvent.
Why Many Landlords Will Now Consider Selling Up
1. Diminishing Returns on Investment
With tax increases reducing net rental yield — and property price growth slowing in many regions — landlords may no longer achieve the returns they expected when entering the market.
When total returns (yield + capital growth) decline, selling becomes increasingly appealing.
2. Rising Risks With Lower Rewards
Being a landlord has become significantly more complex:
-
More documentation
-
Stricter regulations
-
Higher penalties for non-compliance
-
Longer notice periods
-
Increased obligations for repairs and tenant security
For many, the balance between risk and reward has shifted to breaking point.
3. Exit Opportunities in a Cooling Sales Market
Many landlords may choose to sell sooner rather than later, hoping to beat any future softening in prices.
If enough follow this path, the market may see a surge of ex-rental properties being listed for sale.
Impact on Renters
Short Term: Increased Competition and Higher Prices
Tenants should expect:
-
Higher rents as landlords pass on increased taxation
-
More competition as supply tightens
-
Potential instability if their current landlord decides to sell
Medium to Long Term: Structural Change in the PRS
As individual landlords sell up, the market may shift towards:
-
More institutional landlords
-
Fewer small-scale private landlords
-
Larger, professionally managed portfolios
While this could increase professionalism, it may reduce variety and affordability in available rental stock.
Impact on the Wider Housing Market
1. More Stock for Buyers
If landlords exit, more properties may hit the sales market — potentially good news for first-time buyers.
2. Price Pressure at Certain Property Levels
Smaller homes and flats — common rental stock — could see increased supply, placing downward pressure on prices.
3. Long-Term Pressure for Government Intervention
A reduced private rental sector risks:
-
Higher homelessness pressures
-
Increased demand for social housing
-
Greater reliance on Build-to-Rent schemes
This Budget may ultimately force the government to address the UK’s chronic shortage of rental housing more directly.
What Landlords Should Do Now
-
Recalculate your rental income using the new tax rates
-
Review financing arrangements, especially if mortgage terms expire soon
-
Consider restructuring through limited-company ownership if appropriate
-
Plan ahead for compliance costs and potential rental price adjustments
-
Evaluate your long-term strategy — is your property portfolio still delivering what you need?
