Autumn Budget 2026: What London Landlords Need to Know

Autumn Budget 2026 raises personal tax rates on rental income from April 2027 and confirms details of the High Value Council Tax Surcharge. London landlords should carefully review ownership structures, net returns, and exposure to property-related costs.

Key Takeaways:

• Personal tax rates on property income will rise by two more percentage points from April 2027, bringing rates to 24%, 44% and 49%.
• The government has confirmed more details of the High Value Council Tax Surcharge, including exemptions, discounts, and provisions for empty properties.
• Eligible households in England will receive a £100 Household Energy Payment from January 2027, alongside an extension of the electricity VAT cut.
• An additional £1.5 billion will support delivering around 10,000 social and affordable homes in England.
• Landlords should reassess their rental income, operating expenses, and ownership arrangements ahead of the upcoming tax changes.

How the Autumn Budget 2026 Affects London Property Owners

The Autumn Budget 2026, delivered by Chancellor John Healey on 28 October, introduces changes that could influence property owners and landlords across England.

For London landlords, the biggest announcement is a further increase in income tax rates on property income.

The government also confirmed details of the High Value Council Tax Surcharge, which will affect owners of qualifying high-value residential properties, many of which are in London.

According to the House of Commons Library Briefing on High-Value Homes, 67% of all properties sold for £2 million or more in England are in London.

Although the Budget does not introduce a wholesale overhaul of property taxation, these measures could influence rental profitability, investment decisions, and the cost of holding residential property.

1. Higher Income Tax Rates on Rental Property

One of the most important announcements for individual landlords is the increase in income tax rates applied to property income.

“I am increasing the rates of tax on income from property and savings by a further two percentage points from April 2027, with no change to tax on income from dividends and no change to tax on income from employment.” – Budget 2026 speech as delivered by Chancellor John Healey

The Budget 2025 had already announced a two-percentage-point increase from April 2027. The Autumn Budget 2026 adds a further two-percentage-point increase, which will bring the rates to:

• Basic Rate: 24%
• Higher Rate: 44%
• Additional Rate: 49%

These rates apply to individuals and partnerships receiving rental income in England, including London.

What this means for London landlords

Landlords who own rental properties in their personal names could see a higher proportion of their taxable property income go to tax. This could reduce their net income, especially for multi-property or high-value property owners.

For example, a landlord with £20,000 in taxable property income would pay £800 more in income tax at the basic rate (24%) than at the old 20% rate. At the higher rate (44%), the same taxable amount would also add £800 in tax compared with the old 40% rate.

These are illustrative calculations, not estimates of actual final tax bills for landlords. Actual liability will always depend on taxable income, allowances, and the landlord’s personal circumstances.

The changes apply to personal property income tax, not automatically to every property-owning business. Landlords operating through limited companies are generally subject to corporation tax on company profits instead. They should seek professional advice before changing their ownership arrangements.

2. Further Details on High Value Council Tax Surcharge

The government confirmed further details on the High Value Council Tax Surcharge (HVCTS), first announced in the Autumn Budget 2025.

The surcharge will apply to qualifying residential properties in England valued at £2 million or more from April 2028. Property owners, not occupiers, will pay this surcharge. This makes it relevant to owners of high-value London homes.

The original surcharge bands scale progressively based on asset value.

• £2,500 annually for properties valued at £2 million to £2.5 million
• £3,500 annually for properties valued at £2.5 million to £3.5 million
• £5,000 annually for properties valued at £3.5 million to £5 million
• £7,500 annually for properties valued at more than £5 million

The 2026 Autumn Budget confirms this scheme includes:

• Deferral arrangements for eligible property owners
• Discounts and exemptions for qualifying circumstances
• An additional 100% premium for empty and unoccupied properties for 12 consecutive months or more

What this means for London landlords

Owners of qualifying high-value properties should factor the surcharge into the cost of holding their assets. Landlords with properties that remain vacant for extended periods should also understand how the added premium could affect their financial stability.

The government has indicated that the surcharge will apply to fewer than 1% of properties nationally, but as mentioned, 67% of high-value properties are in London. This means London landlords will be more affected than those in other parts of England.

3. Energy Bill Support and Operating Costs

The Autumn Budget 2026 also introduces measures to ease household energy costs.

“This winter, for 20 million households in council tax bands A-D, I am announcing a £100 energy payment for households. Paid directly into people’s bank accounts to deal with rising energy bills, a £2.6 billion scheme to take the pressure off in the coldest months and see people through to the Spring.” – Budget 2026 speech as delivered by Chancellor John Healey

From January 2027, eligible households in England in Council Tax bands A to D will receive a £100 Household Energy Payment. The government is also extending the zero-rate VAT treatment of domestic electricity until July 2027.

What this means for London landlords

For London landlords, the distinction between household support and property operating costs matters. The £100 payment is intended for eligible households, not necessarily landlords who own rental properties. Whether a landlord benefits will depend on whether they personally qualify as a household recipient.

For landlords who include utilities in their rental arrangements (e.g., short-term rentals), changes to energy costs may affect their operating expenses. Landlords can manage and control overheads by monitoring consumption, reviewing utility arrangements, and maintaining energy-efficient properties.

4. More Investment in Social and Affordable Housing

The government has allocated an additional £1.5 billion to the Social and Affordable Homes Programme, supporting the delivery of approximately 10,000 additional homes in England.

“Today, I am providing an additional £1.5 billion for the Social and Affordable Housing Programme, taking our total government commitment backing for council housing to £40 billion.” – Budget 2026 speech as delivered by Chancellor John Healey

The funding is set aside for Social Rent, specifically council housing, and will contribute to more than £40 billion worth of social and affordable housing investment over 10 years.

The Budget also confirms the £4.7 billion Your First Home equity-loan scheme, which aims to make homeownership more affordable to around 70,000 first-time buyers. 

What this means for London landlords

The government has long worked to increase housing supply and improve access to homeownership. While this is expected to affect demand in the private rental market in the long term, it will still depend on whether the homes are delivered, how quickly they become available, and whether they meet local housing demand.

For private landlords, increased affordable housing provision is worth monitoring, but it shouldn’t always be seen as an immediate threat to rental demand or property values.

What London Landlords Should Do Next

Here are 5 practical steps you can take right now:

1. Recalculate your rental income after tax. Forecast your expected returns using the new, higher property income taxes.
2. Review ownership arrangements, especially if you own several properties. Discuss the tax implications of personal versus company ownership with a qualified accountant before making structural changes.
3. Check your property’s value. High-value homeowners should understand the High Value Council Tax Surcharge and its eligibility rules.
4. Monitor operating expenses. Review utility costs, housekeeping, maintenance, and other recurring expenses, and look for opportunities to increase your net returns.
5. Review your letting strategy. Consider whether your current rental model, pricing, and occupancy rates maximise your property’s income potential. Under the new budget, traditional long-lets with a static rent cap may no longer cover your tax liabilities. Switching to a flexible, data-driven framework is often the most effective way to close this gap.

For landlords managing short-, mid-, or long-term rentals, the goal is to understand how gross rental income, operating expenses, and net rental revenue relate.
