The Autumn Budget will be announced on Wednesday, 26 November. Normally by this point in the week, we’d be talking about what might change for developers, lenders, buyers and brokers. But this year feels noticeably different.
Not because the Budget itself is expected to be dramatic, but because of the way the Government has handled the run-up. Months of Budget “leaks”, hints and shifting signals have created a level of uncertainty the property market hasn’t experienced for years.
The market hasn’t waited for the Chancellor’s speech, it has already slowed down.
Ahead of the Autumn Budget Announcement 2025 we breakdown:
- an explanation in simple language what may appear in the Budget
- an explanation why the housing and development sector has already stalled before any announcement has even been made
Budget leaks have created paralysis, not clarity
The Government has repeated a familiar tactic: drip-feeding potential measures into the press to soften the impact. But after months of U-turns and mixed signals, this has had the opposite effect.
Instead of reassurance, the approach has delivered hesitation and mistrust.
- Developers aren’t sure what the final rules will be
- Buyers are delaying purchases
- Investors are waiting for certainty
- Lenders are watching market behaviour, not government hints
This has created a rare scenario for November:
the property market has slowed down before the Budget rather than after it.
How uncertainty is already freezing activity
1. Buyers have hit the pause button
RICS has reported a clear softening in buyer sentiment. November is always quieter, but pre-Budget nerves are amplifying the slowdown. Buyers don’t want to commit on Tuesday only to discover on Wednesday that tax rules or incentives have changed.
This feeds directly into developers’ forward sales and pipeline planning.
2. Developer confidence has dipped sharply
The biggest fear right now is tax. Even rumours of property-related taxes are enough to cause developers to rethink their plans. This includes talk of:
- annual property taxes
- mansion-tax-style measures
- potential land or high-value home charges
As a result, developers are:
- delaying new acquisitions
- rethinking exit strategies
- accelerating disposals in case changes take effect
Multi-year projects rely heavily on stable fiscal policy. When that becomes unclear, decision-making stalls.
3. Some developers are accelerating disposals
Speculation has pushed some developers to bring forward land or asset sales, releasing sites or restructuring pipelines early to avoid potential tax shifts.
This has led to unusual patterns:
- faster-than-expected disposals
- divestment from certain assets
- paused acquisition strategies for new sites
4. Financing conditions are tightening
This uncertainty doesn’t just affect developers, lenders feel it too. Across the market, some lenders are already “lifting up the drawbridge” on certain locations and property types.
While Assetz Capital remains committed to supporting quality SME projects, we are seeing:
- stricter lending criteria
- slower approvals
- additional conditions
- rising caution across the market
This environment hits refurb, PDR, bridging and SME development projects hardest.
What the Budget might include (in simple terms)
We’re not expecting dramatic changes, but several areas could still affect developers and brokers:
Property taxes
Possible tweaks to:
- Stamp Duty
- Capital Gains Tax
- Landlord and BTL rules
These influence buying behaviour, exit strategies and refinancing decisions.
Planning and housing measures
SME developers will be watching for:
- faster planning decisions
- brownfield and regeneration support
- PDR encouragement
- funding for councils to unblock backlogs
Anything that speeds up planning or adds certainty would be welcome.
Investment incentives
Potential allowances or reliefs that help borderline schemes stack up, including:
- plant and machinery allowances
- remediation relief for contaminated land
- support for regeneration or retrofit
Economic tone and signals
The Budget’s messaging will influence borrowing conditions.
A cautious tone could extend the period of higher borrowing costs.
A confident tone could lift market sentiment.
What borrowers and brokers should do now
Borrowers / developers
- Revisit assumptions on your current deals
- Think carefully about timing of purchases, exits or refinances
- Stress-test build costs and end values
- Speak to lenders early if changes could impact your plans
Brokers
- Let clients know clarity is coming
- Identify cases sensitive to tax or transaction timing
- Prepare quick guidance for Budget day
- Expect higher demand for clarity and interpretation
Final thought
The run-up to the Budget has created temporary friction across the sector. Confidence has been bruised, pipelines have slowed and lenders have become more cautious, not because of confirmed policy, but because of prolonged uncertainty.
The good news? Once the Chancellor speaks, the market will finally have the clarity it needs to move again. Whether the announcements are positive or challenging, certainty itself is what will help buyers, developers and lenders regain momentum.
Assetz Capital will be ready with clear, practical guidance including commentary from our CEO Stuart Law, to help you understand exactly what the Budget means for your next project.
