Seventy-four days. That is how long it currently takes to sell a home in the South East, according to Rightmove’s October 2026 data, with a third of listings already carrying a price cut. Against that backdrop, Chancellor John Healey stands up on Wednesday 28 October 2026 to deliver an Autumn Budget that will shape mortgage costs, landlord taxes and first-time buyer options across Canterbury, Thanet, Ashford, Dover and Maidstone. For Autumn Budget 2026 Kent homeowners, the headline news so far is as much about what has been ruled out as what remains live.

This matters because speculation has swirled for months about property tax reform. Some of it has already been shut down by government sources. Some remains genuinely open. Knowing the difference helps Kent buyers, sellers and landlords plan sensibly rather than react to headlines.

Key Takeaways

• Stamp duty changes have been ruled out for this Budget, and a single annual property tax replacing stamp duty and council tax is also off the table “at this moment in time” [1][2].
• The High Value Council Tax Surcharge on £2m+ homes is already legislated from April 2028; lowering the threshold to £1.5m has reportedly been ruled out after Labour backbench opposition [1][3].
• A reported rise in Capital Gains Tax on residential property is said to be ruled out, keeping rates at 18%/24% [1].
• Your First Home scheme details are expected at the Budget: a 2.5% deposit, 20% government equity loan and 77.5% mortgage for new-build buyers, subject to income and local price caps [1][2].
• South East house prices are down 0.8% annually (ONS) and average two-year fixed mortgage rates sit at 5.93%, so a RICS Home Survey and independent valuation matter more than ever in a flat Kent market [4][5].

Autumn Budget 2026 Kent Homeowners: What’s Already Ruled Out

Several property tax ideas floated by think tanks and commentators over the summer have been formally dismissed ahead of Wednesday.

Stamp duty reform. Housing Secretary Andy Burnham has ruled out changes to stamp duty land tax in this Budget, despite lender pressure for a “bazooka” overhaul to kickstart transactions [1][6]. For Kent buyers hoping thresholds might shift before completion day, this means current rates and bands remain the planning assumption.

A single annual property tax. Proposals to merge stamp duty and council tax into one national property tax have been ruled out “at this moment in time,” according to the Housing, Communities and Local Government Secretary [1][2]. This was always a longer-term structural reform rather than a near-term Budget measure, and Kent homeowners should not expect it to appear this year.

Lowering the mansion tax threshold. The High Value Council Tax Surcharge, already legislated to take effect from April 2028, applies to England homes valued at £2 million or more, with annual charges ranging from £2,500 to £7,500 [1][3]. Speculation that the Treasury might cut this threshold to £1.5 million has reportedly been ruled out following opposition from Labour MPs [1]. Very few Kent properties sit near either threshold, but the policy direction is still worth monitoring for high-value coastal and rural estates.

A Capital Gains Tax rise on residential property. Reports suggest a CGT increase has also been ruled out, keeping gains on residential property taxed at 18% and 24% [1]. This will reassure some landlords weighing up whether to sell before the Budget.

“The direction of travel is targeted changes at the margins, not wholesale reform of property taxation this year.”

What’s Still Live for Kent Buyers and Landlords

Not everything is settled. Several areas remain genuinely open heading into Wednesday.

Your First Home Scheme

This is arguably the biggest opportunity for Kent first-time buyers. The framework, expected to be detailed in full at the Budget, involves:

• A 2.5% deposit from the buyer
• A 20% government equity loan
• A 77.5% mortgage
• Eligibility limited to new-build homes from participating developers
• Income and local price caps
• An initial interest-free period on the equity loan [1][2]

With new-build developments active around Ashford and Dover, this scheme could materially widen access for buyers currently priced out by deposit requirements.

Landlord Taxation and Holiday Lets

Landlords already face a confirmed 2 percentage point rise in income tax on rental profits from April 2027 [2]. The Budget may add further detail on how this applies, alongside continued scrutiny of furnished holiday let tax treatment, relevant to landlords in coastal Thanet and Dover letting markets [2].

Renters and Local Housing Allowance

Housing sector bodies are calling for Local Housing Allowance to be restored to cover 30% of local market rents, but this remains a demand rather than a confirmed measure [1][7].

Energy Support and Green Spending

The Warm Home Discount may rise from £150 to £250, while the Boiler Upgrade Scheme’s £7,500 grant could face cuts [1]. Both would affect Kent homeowners planning energy efficiency upgrades this winter.

Inheritance Tax and the Family Home

Early-stage proposals to make the main residence exempt from inheritance tax remain speculative and should not be treated as likely for this Budget [1][3].

Why the Kent Market Context Matters This Week

Measure	Figure	Source
South East average house price	£380,000, -0.8% annually	ONS, Aug 2026 [4]
South East asking price (Rightmove)	£475,582, -0.9% annually	Rightmove, Oct 2026
Average time to find a buyer	74 days	Rightmove, Oct 2026
Homes with a price cut	34%	Rightmove, Oct 2026
Average 2-year fixed mortgage rate	5.93%	Moneyfacts, Oct 2026 [4]

With South East prices falling annually and mortgage rates still close to 6%, Kent sellers cannot assume last year’s valuation still applies. A flat or softening market means overpricing risks the property sitting unsold for months, while underpricing leaves money on the table.

Practical Steps for Kent Homeowners Before and After the Budget

1. Get an independent valuation. A RICS Home Survey or chartered surveyor valuation gives an evidence-based figure, not an estate agent estimate designed to win instructions.
2. Review your mortgage timeline. With average two-year fixes at 5.93%, compare against your current deal well before any renewal date.
3. Check Your First Home scheme eligibility once full criteria are published, particularly if considering new-build developments in Ashford or Dover.
4. Landlords should model the April 2027 tax change now rather than waiting, especially where profit margins are already thin.
5. Avoid reacting to unconfirmed rumours such as inheritance tax changes to the family home, which remain speculative.

FAQ: Autumn Budget 2026 Kent Homeowners

Will stamp duty change for Kent buyers this Budget? No. Stamp duty changes have been ruled out for this Budget [1][6].

Could my council tax be replaced by a new property tax? A single annual property tax replacing stamp duty and council tax has been ruled out “at this moment in time” [1][2].

Does the mansion tax affect typical Kent homes? Unlikely. The High Value Council Tax Surcharge applies from April 2028 to homes worth £2 million or more, and lowering the threshold to £1.5 million has reportedly been ruled out [1][3].

What is the Your First Home scheme? A new-build buyer scheme involving a 2.5% deposit, 20% government equity loan and 77.5% mortgage, with full details due at the Budget [1][2].

Are landlords facing new tax rises? A 2 percentage point rise in income tax on rental profits is confirmed from April 2027 [2]. CGT rises have reportedly been ruled out [1].

Why does a surveyor valuation matter now? With South East prices down annually and over a third of listings seeing price cuts, an independent valuation helps avoid overpricing or underpricing in a flat market.

Conclusion

For Autumn Budget 2026 Kent homeowners, Wednesday’s announcement is less about sweeping property tax reform and more about targeted measures at the edges: a new first-time buyer scheme, confirmed landlord tax changes, and energy support adjustments. Stamp duty, a merged property tax, mansion tax threshold cuts, and CGT rises have all reportedly been ruled out. Against a Kent market where prices are softening and mortgage rates remain near 6%, the sensible next step is to get an independent valuation, review mortgage options, and watch Wednesday’s detail on Your First Home before making buying or selling decisions.
