UK Buy-to-Let Market Update: Autumn 2025
As we head toward the end of 2025, the UK buy-to-let (BTL) market continues to navigate a mix of opportunity, challenge and regulatory change. For letting agents, landlords, and investors, understanding where things stand is more important than ever. Below is a summary of recent trends, pressures, and what to watch out for.
What’s happening right now
​
Mortgage / borrowing costs are easing
​​
-
Two-year fixed BTL mortgage deals are averaging 4.88%, down from ~5.35% a year ago.
-
Five-year fixed BTL deals are about 5.21%, slightly lower than a year back.
-
Overall, the borrowing cost drop is partly due to lenders competing harder to attract landlords.
​
More product choice
​​
-
The number of BTL mortgage products has roughly doubled since September 2022.
-
UK Finance data for Q1 2025 shows ~58,347 new BTL loans, worth ~£10.5 billion, up by ~39% in number and ~47% in value over Q1 2024.
Rental yields & demand remain relatively strong
​​
-
Rental yields in the UK are holding up; UK Finance reports an average gross yield of ~6.94% in Q1 2025.
-
Tenant demand remains high while supply of rental homes is under pressure. Many landlords are pulling back.
​
Landlords exiting, supply shrinking
​
-
There is a continued decline in the number of rental listings. The RICS landlord instructions index is negative, indicating more landlords are leaving the market than entering.
-
Several legislative & tax changes are in play or being proposed, adding uncertainty. Issues include proposed changes to tax treatment, national insurance levies, and new tenant protection laws (e.g. ban on “no-fault” evictions).
Regional shifts in investment
​​
-
Investment is moving away from London and the South East toward the Midlands, North West, North East, and Yorkshire & Humber. These areas are seeing a larger share of new BTL purchases.
What are the challenges
-
Regulatory & tax/headwinds: Changes to tax reliefs (e.g. mortgage interest relief), potential new levies, more stringent tenant rights laws are creating concern among landlords.
-
Uncertainty & risk: Because of upcoming Budget announcements, and evolving law (Renters’ Reform Bill etc.), many landlords are cautious about committing new investments.
-
Affordability pressures: As borrowing falls, margins are still tight for many depending on location, condition of property, maintenance costs etc. Plus inflation and running costs remain a concern.
Opportunities & silver linings
-
Lower borrowing costs + more product choices = better chances for landlords to refinance or take on new properties with more favourable terms.
-
Rises in rental yields, especially in regions outside London, make investment more attractive.
-
Regions with strong tenant demand but less competition for stock offer good value.
What this means for landlords
-
Be strategic about where you invest: look at regional markets, yields, tenant demand. Your returns may be much better outside London / South East.
-
Understand upcoming legal / regulatory risks. Getting ahead of compliance (tenant rights, standards, taxes) will be essential.
-
For existing portfolios, reviewing financing arrangements (can you refinance? can you lock in better fixed rates?) could help preserve margins.
What to watch next
-
The UK Budget (November) — any new tax/levy proposals could materially affect profitability.
-
Progress of the Renters’ Reform Bill, including any changes to eviction rules or landlord obligations.
-
Movements in mortgage rates in the residential vs BTL space. If residential rates creep up, that cost pressure will flow through.
​
The current UK buy-to-let landscape is one of cautious optimism. For landlords, there are real opportunities: falling borrowing costs, steady yields in some areas, and greater product choice. But the environment is not without risk: regulatory change, tax pressures, and supply constraints mean that strategy, flexibility, and careful financial planning are now more important than ever.
