UK Budget 2025: A Stable Outlook for Buy-to-Let Investors

The government confirmed the introduction of a High-Value Council Tax Surcharge from April 2028, applying only to properties valued above £2 million. These homes represent a very small slice of the UK market and are concentrated primarily in prime central London.

• £2m–£2.5m: £2,500 per year
• £5m+: up to £7,500 per year
• Applies to roughly 0.5% of national housing stock

For most landlords — especially those investing in emerging city-centre growth markets such as Manchester, Leeds, Birmingham and Liverpool —this is entirely irrelevant. Even for high-net-worth investors purchasing at the top end of the London market, the surcharge is small relative to the scale of long-term returns.

Bottom line
Minimal impact on mainstream or even upper-mid buy-to-let. This is a niche measure affecting only ultra-prime assets.

From April 2027, landlords who hold property in their personal name will see a small rise in tax rates on rental income.This increase is incremental — not structural — and does not alter the basic attractiveness of buy-to-let as an income-producing asset.

• Basic rate: 22% (up from 20%)
• Higher rate: 42% (up from 40%)
• Additional rate: 47% (up from 45%)

These modest increases are arriving at a time when rents are growing faster than inflation in many major cities. According to major property portals, UK rents have increased by between 7% and 11% annually in most urban centres for three consecutive years. In other words, yield growth alone is likely to absorb much of the headline tax change.

Bottom line
A minor rise in tax, significantly outweighed by tightening supply and healthy rental growth — especially for those investing through efficient structures.

Despite persistent rumours, there were no new stamp duty surcharges, no revisions to existing SDLT bands, and no new capital gains tax changes affecting landlords.

This is one of the most meaningful outcomes of the entire Budget. Investors can continue to structure acquisitions and exits without unexpected upfront frictional costs or punitive new disposal rules.

Bottom line
A major win for investor confidence. Transactional stability makes today an ideal environment for strategic purchasing.

The UK rental sector’s underlying fundamentals are unchanged and incredibly favourable to landlords. The imbalance between supply and demand continues to drive robust rent growth — a trend supported by migration, shrinking household sizes, and delayed first-time buyer activity due to affordability challenges.

• High tenant demand across all major cities
• Record enquiries per available property
• Limited new supply entering the market
• Strong rental growth forecast through 2026–2028

Nationally, rental listings remain near historic lows, while the number of tenant enquiries per listing remains at record highs. This sustained imbalance is one of the most reliable indicators of continued rental price growth.

As smaller landlords gradually exit and regulatory standards tighten, the rental landscape is beginning to favour more professional, better capitalised investors — creating long-term stability and improved returns.

Bottom line
Strong fundamentals, reduced competition, and consistent rent growth create a compelling environment for investors.

SPVs remain the most tax-efficient and scalable route for serious landlords and portfolio builders. With corporation tax locked at 25% for the duration of the parliament, investors benefit from certainty, stability and a structure that offers a solution to the personal income tax rate increases mentioned earlier.

• Corporation tax fixed for the entire parliament
• No new SPV-specific taxes announced
• Dividend tax rises slightly from 2026 but remains manageable
• Ideal for refinancing and long-term portfolio growth

As individual landlords exit, SPVs have a clear advantage: they can acquire high-performing assets, often with less competition, while benefiting from strengthened rental pricing due to reduced supply.

Bottom line
SPVs continue to offer the most efficient and scalable structure. The Budget reinforces their position rather than challenging it.

Although the HVCTS introduces a small additional cost at the ultra-prime level,
the broader fundamentals of the high-end UK property market remain strong.
London continues to attract international capital, and luxury rental demand is robust among corporate tenants, diplomats,
and relocating executives.

Bottom line
Ultra-prime remains a niche but resilient market. Investors purchasing below the £2m threshold face no new charges.

The strongest investors will not react emotionally to headlines — they will position themselves strategically. Here are
key actions worth considering:

Review your investment structure — moving future purchases into an SPV may provide significant long-term tax savings.
Model your post-2027 yields — factor in both tax changes and continued rental uplift.
Prioritise modern, energy-efficient stock — these homes meet future regulatory requirements and appeal to high-quality tenants.
Plan ahead for tenancy reform — the 2026 regulatory updates will favour organised, compliant landlords.
