A simple, jargon-free update from Ashton Lee Surveyors
The Budget announcements can feel overwhelming, especially when you’re preparing to buy or sell a home. We’ve broken down the changes that matter most to individuals and families navigating the property market over the next few years.
No political spin — just the facts that affect your move, your mortgage and your long-term plans.
1. The New ‘Mansion Tax’ – Higher Stamp Duty for High-Value Homes
One of the most talked-about measures in this Budget is what many are referring to as a “mansion tax.”
What’s actually happening?
The government is introducing a new, higher band of Stamp Duty Land Tax (SDLT) for properties above acertain value threshold. This mainly affects higher-value homes.
What this means:
- Buyers of high-value homes will face higher upfront costs.
- Sellers may see buyers adjusting offers to account for the increased tax.
- Most normal home purchases remain unaffected.
2. Tax changes that may influence the wider market (from 2027)
New tax rules affecting landlords and savings could indirectly influence supply and demand:
- Some landlords may sell, increasing property availability.
- Higher rents may push some tenants into buying sooner.
- Savings tax rises may slow deposit-building for some buyers.
3. HMRC digital changes may streamline the buying process
From 2026–2027, HMRC will shift to digital-by-default communication. Faster updates may allow mortgagelenders to verify income more quickly, reducing delays.
4. Housing Market Predictions from the OBR
- House prices: +3% in 2025, then around +2.5% annually through 2030.
- Mortgage rates: Expected to settle near 5% by 2029.
- Sales activity: Rising from 1.1m to 1.3m by 2029.
What this means:
Buyers – steady market, gradual increases.
Sellers – stable demand but not a return to 2021-style bidding wars.
Buying or Selling? Key Tips
For Homebuyers:
- Start mortgage conversations early.
- Budget for gradual price rises.
