The UK buy-to-let (BTL) mortgage market is under significant pressure in April 2026. Average fixed BTL rates have risen sharply after the Middle East conflict pushed up swap rates, while the Renters' Rights Act taking effect on 1 May 2026 is driving one of the largest landlord exits the sector has ever seen.
Where BTL rates are today
According to Moneyfacts data, BTL rates rose materially between early March and early April 2026 as global wholesale volatility reached the mortgage market:
| Product | 1 March 2026 | 1 April 2026 | Change |
|---|---|---|---|
| Average 2-year fixed BTL | 4.66% | 5.44% | +0.78% |
| Average 5-year fixed BTL | 5.05% | 5.75% | +0.70% |
The number of BTL mortgage products available has also contracted. Which? analysis shows that while the first three months of 2026 consistently saw over 5,000 BTL products on the market, by 7 April 2026 this had fallen to 4,694 — a clear sign that lenders are pulling back in response to volatility.
The landlord exodus in numbers
The scale of the exit from the private rented sector (PRS) is significant. Multiple data sources point in the same direction:
- 93,000 — approximate number of BTL landlords who exited the market in 2025, according to LandlordBuyer.
- 2.86 million — total landlords in England, down 1.04% in just one year (NRLA data).
- 31% — share of landlords who plan to reduce the size of their portfolio, per the English Private Landlord Survey.
- 16% — share considering selling all rental properties within two years.
- 220,000 households — roughly 5% of the PRS — that Pepper Money forecasts could leave the sector by end of 2026.
- 65,000+ of those exits are directly attributed to the Renters' Rights Act.
The perfect-storm dynamics
Landlords are facing pressure from every direction at once:
- Renters' Rights Act (1 May 2026) — Section 21 abolished, fixed-term tenancies ended, three-month rent arrears threshold replacing two, possession times expected to worsen from the current 33.8-week average.
- Mortgage costs — Section 24 still restricts mortgage interest relief for higher-rate taxpayers. At 5%+ rates, many leveraged BTLs no longer produce a meaningful net yield.
- EPC C deadline — all rental properties must reach EPC C by 1 October 2030, with a £10,000 spending cap per property.
- Stamp Duty surcharge — additional property surcharge increased from 3% to 5% in April 2025, adding thousands to any new BTL purchase.
- Property income tax rise — the Chancellor announced a 2-percentage-point rise in property income tax rates from April 2027.
The flip side — rate and exit pace moderating
TwentyCi data shows the exodus is not entirely one-way. In February 2026, year-on-year rental inflation was 2%, down from 4% at the same point in 2025, and the number of former rental properties being listed for sale has reduced in 2026 so far. However, only 4% of landlords report actively acquiring new properties — so the imbalance between sellers and new entrants remains.
Recent analysis from TwentyCi suggests rental property listings from exiting landlords have fallen around 45% in early 2026, indicating the initial rush may have peaked while the underlying trend continues.
What this means for brokers and landlords
- Stress tests are tightening — at 5.44% on a two-year fix, the Prudential Regulation Authority's 5.5%+ stress test becomes effectively binding on most new BTL applications.
- Top slicing — landlords with strong personal income may still qualify via top-slicing where rental income alone falls short.
- Limited company BTL — the share of BTL arranged through limited companies continues to grow, insulating higher-rate taxpayers from Section 24 restrictions.
- EPC-linked products — some lenders now price preferentially for properties rated EPC A–C, with discounts for properties at A or B.
- Portfolio landlords — lenders increasingly want to stress-test the whole portfolio (four+ properties) rather than the single application in front of them.
The outlook
Short term, much depends on the Middle East situation and the Bank of England's decision on 30 April. If oil prices settle and swap rates ease, BTL pricing may retrace some of the April rise. Longer term, structural pressures — regulation, taxation, compliance costs — continue to push marginal landlords out of the market, while larger portfolio investors and build-to-rent operators consolidate the sector.

FAQ
Will BTL mortgage rates fall in 2026?
Pricing follows swap rates and expectations for Bank Rate. If energy prices settle and inflation resumes its path back towards 2%, further modest cuts are possible. If the Middle East situation escalates, rates could rise further.
Should I incorporate my BTL portfolio?
It depends on your marginal tax rate, portfolio size, long-term plans and the stamp duty cost of transferring into a limited company. This is genuinely a decision for a qualified accountant, not a broker alone.
What is the impact of the Renters' Rights Act on BTL lending?
Lenders are reviewing criteria, particularly around possession timelines and deposit compliance, but no major lender has withdrawn from the BTL market.
