The Autumn Budget 2026, delivered by Chancellor John Healey on 28 October, brings changes that matter to homeowners, sellers, landlords and first-time buyers. From a new first-time buyer ISA and the Your First Home equity loan scheme to cheaper council borrowing for housing, here is what the Budget means for property, and what to consider if you are thinking of selling your house fast.
The Autumn Budget 2026 at a Glance
- First-time buyers: the new Your First Home scheme aims to help 70,000 people onto the property ladder, a First Time Buyer ISA replaces the Lifetime ISA from April 2029, and the Lifetime ISA charge for buying a first home above £450,000 falls to 20% from 29 October.
- Housing supply: an extra £1.5 billion for social and affordable housing, funding for hundreds more planners, and an exemption from biodiversity net gain requirements for smaller brownfield developments.
- Stamp duty: no change to residential rates.
- Mansion tax: the High Value Council Tax Surcharge on homes worth £2 million or more is still due to start in April 2028.
- Landlords: tax on rental income rises to 24%, 44% and 49% from 6 April 2027, a further two percentage points on top of the increase already planned.
What Does the Mansion Tax Mean for Homeowners?
The mansion tax, officially the High Value Council Tax Surcharge, is an extra yearly charge on expensive homes in England. It applies to properties worth £2 million or more and is due to start in April 2028. The annual charge depends on the value of your home, sits on top of normal council tax and will rise with inflation each year. The Office for Budget Responsibility (OBR) estimates around 165,000 properties will be in scope in 2028/29.
| Property value | Annual surcharge |
|---|---|
| £2 million to £2.5 million | £2,500 |
| £2.5 million to £3.5 million | £3,500 |
| £3.5 million to £5 million | £5,000 |
| Over £5 million | £7,500 |
Elliot Castle, CEO & Founder of We Buy Any Home, said: “An annual charge on owning a property is a different issue from the costs of selling it. Homeowners need to understand which rules apply to them rather than assume every property-tax headline means they will pay more when they move.”
“But let’s be clear about who this hits. Owning a home worth more than £2 million today doesn’t mean you have thousands of pounds a year spare to pay a mansion tax. Many of these owners bought decades ago and have simply watched their home rise in value.”
If you own a higher-value home and are weighing up a move, the surcharge is one more cost to factor into your decision. It is worth getting a valuation and speaking to a professional adviser before you decide. Our selling house guides explain the options.
Does the Budget Change Stamp Duty?
No. HMRC’s Budget 2026 rates and allowances show no change to residential stamp duty.
Stamp duty rates in England and Northern Ireland have not changed since 1 April 2025: 0% up to £125,000, 2% up to £250,000, 5% up to £925,000, 10% up to £1.5 million and 12% above that. First-time buyers pay nothing up to £300,000, with relief available on homes up to £500,000, and an extra 5% applies on each band if you are buying a second home, holiday let or buy-to-let. If you are selling and buying, stamp duty on your next home is part of the total cost of moving, so check the current rates before you commit.
How Will the Budget Affect House Prices and the Property Market?
The Budget left stamp duty alone, which may come as a relief to sellers who feared a shock, although landlords face a higher tax rate on rental income from April 2027. According to the BBC’s coverage of the speech, the Chancellor said the war in Iran has pushed up energy costs and interest rates, and those pressures matter more to buyers and sellers than any single Budget measure.
Many sellers have faced uncertainty in the run-up to the Budget, with some waiting to see what was announced before deciding whether to list. Budget day removes some of that uncertainty, although buyers and sellers will still need time to react. Pricing realistically matters in a cautious market: our 2026 Property Markdown Index found overpricing costs UK homeowners an average of £33,597.
Elliot said: “Governments are temporary, but land is permanent. So stop waiting for the dust to settle, because by the time it does, the market will already be moving without you.”
What Does “Your First Home” Mean for First-Time Buyers?
Your First Home is the government’s new equity loan scheme for first-time buyers, which it says will help 70,000 people onto the property ladder. The Chancellor confirmed £4.7bn of government-backed lending, according to Which?. It is for new-build homes only, with a deposit of between 2.5% and 15% and a government equity loan of 20%, interest-free for five years. Household income is capped at £110,000 (£140,000 in London), and price caps follow local authority median prices, up to £650,000 in inner London and £500,000 in outer London. Pre-registration opens by the end of December 2026, with first loans expected from April 2027, according to Propertymark.
The Budget also replaces the Lifetime ISA with a First Time Buyer ISA from April 2029, with up to £4,000 a year in savings and a 25% government bonus on qualifying withdrawals, according to Which?. Existing Lifetime ISA holders can keep contributing, and from 29 October the charge for using a Lifetime ISA to buy a first home above the £450,000 cap falls from 25% to 20%.
Elliot said: “The Government is under enormous pressure to deliver its housing pledge to build 1.5m new homes, and developers need buyers to give them confidence to keep building. This scheme helps both. But if the priority were simply helping first-time buyers overcome the deposit barrier, why exclude someone buying an existing home?”
“Opening it up to every first-time buyer, whether they’re buying a new build or a second-hand home, would really get the property market moving.”
On the new First Time Buyer ISA, Elliot said: “Replacing the Lifetime ISA with a dedicated First Time Buyer ISA is a welcome move. Too many savers have been penalised for buying a home just above the £450k cap, losing some of their own money in the process.”
Because the scheme is aimed at new builds, first-time buyers looking at existing homes may not benefit, which matters for sellers further up a chain. If a sale has fallen through, our guide on what to do when a house sale falls through explains your options.
How Does the Budget Affect Landlords?
Tax rates on rental income will rise to 24% in the basic-rate band, 44% in the higher-rate band and 49% in the additional-rate band from 6 April 2027 in England, Wales and Northern Ireland, according to HMRC’s Budget 2026 rates. That is a further two percentage points on top of the 22%, 42% and 47% set out in 2025.
Elliot said: “Landlords aren’t a bottomless pit that the government can keep raiding. And this tax doesn’t touch landlords with properties in a limited company, it lands on ordinary, hard-working people who might have inherited a property or bought a second one to top-up their income or fund their retirement.”
“Every new cost either pushes rents up for tenants or forces another landlord to sell up and exit the market.”
Landlords weighing up whether to keep or sell a rental property should look at the full picture, including capital gains tax and any tenants already in place. Our guides to selling a tenanted property and selling a tenanted buy-to-let explain how this works.
Will the Budget Help Hit the 1.5 Million Homes Target?
The government has committed to building 1.5 million homes in England this Parliament. GOV.UK says the Budget adds £1.5 billion for social and affordable housing and exempts smaller brownfield developments from biodiversity net gain requirements, while the BBC also reported cheaper borrowing for councils to build housing and no VAT on land sold to social housing providers. Propertymark reports that the OBR expects Your First Home to have only a marginal effect on supply and a slight upward push on house prices, so supply depends on developers and investors being able to build at the pace the target needs.
Elliot said: “The UK is facing a systemic housing shortage, no matter who has been in charge the demand for homes keeps outstripping supply.”
“Setting targets for housing is all well and good, but developers and investors need to feel supported, not targeted by the taxman.”
What Should Homeowners Do Now?
If you are thinking of selling, start by working out what the Budget means for your own situation. Speak to a tax or financial adviser about anything that affects your costs, particularly if you own a higher-value home or let out a property.
Then think about how you want to sell. A traditional sale can take months and depends on buyers’ mortgages and chains, which changes in the market can unsettle. Cash house buyers offer a different route without a chain, and our guide to selling a house fast explains how it works. Our 2026 Property Markdown Index also shows how pricing affects what sellers end up with.
