Rising Interest Rates & Mortgage Market Update (Q2 2025)

Over the past three years, the UK’s interest rate environment has been anything but dull. Following a rapid series of hikes between 2022 and 2023 to tackle runaway inflation, the Bank of England’s base rate peaked at 5.25%. While inflation has since cooled, borrowing costs remain elevated — and property investors are adjusting to the new normal.

So what does Q2 2025 hold for mortgages, landlords, and the wider property market?

1. Where Are Rates Now?

As of May 2025, the Bank of England base rate stands at 4.25%, following two 25-basis-point cuts earlier in the year — most recently on 8 May 2025. This marks a cautious move by the Bank in response to falling inflation (CPI fell to 2.6% in March) and slower economic growth.

For investors, average rates look like this:

• 2-year fixed BTL mortgage: from ~4.04% (HSBC)
• 5-year fixed BTL mortgage: from ~3.94% (HSBC)
• Residential mortgage (5-year fix): ~4.59% (average)

It’s worth noting that these rates typically apply to loans at 60–65% loan-to-value (LTV). Higher LTV loans often attract higher interest rates, especially for less conventional let types (e.g., HMOs or holiday lets).

Rates also vary substantially between lenders — and with some products dipping below 4% for the first time since 2024, it pays to shop around or work with a mortgage broker.

While down from 2023 highs (which peaked around 6.5–7%), rates remain well above the ultra-low environment investors enjoyed pre-2022.

2. What’s Driving Interest Rates in 2025?

Key factors influencing rates today include:

• Inflation: Headline CPI has dropped below 3%, but core inflation (especially services) remains sticky — keeping pressure on the BoE to avoid cutting too quickly.
• Wage Growth: Average earnings are still rising 4–5% annually, sustaining consumer demand.
• Market Expectations: Financial markets are pricing in one more 25 bps rate cut in 2025, with expectations of a slower easing cycle than previously hoped.
• Global Factors: ECB and Federal Reserve policy remain influential. US Treasury yields and geopolitical tensions are contributing to stubbornly high global bond yields, limiting the room for UK rates to fall.

3A. Mortgage Activity: Are Landlords Still Borrowing?

According to UK Finance, BTL mortgage approvals in Q1 2025 were up 12% year-on-year, driven by increased refinancing activity and tentative re-entry from yield-focused investors.

• BTL new purchases are still lagging behind pre-2022 levels, reflecting squeezed margins and tighter affordability tests.
• Remortgages surged in early 2025 as many investors’ fixed deals from 2020–21 matured.
• Nationwide reported that tracker products have regained popularity, with more borrowers speculating on falling rates in late 2025.

In its April 2025 housing market update, Nationwide noted that “confidence among existing homeowners has returned faster than among first-time buyers, with remortgaging demand particularly strong in the landlord segment.”

Meanwhile, lenders remain cautious:

• Stress tests for BTL typically use an interest coverage ratio (ICR) of 145% at a notional rate of 5.5–6%.
• Some specialist lenders have reintroduced green BTL products and interest-only options, with slightly discounted rates.

4. Impact on Buy-to-Let Investors

For landlords, the elevated rate environment presents several challenges:

• Reduced affordability: Especially in southern markets where yields are compressed.
• More cash-heavy deals: Investors need higher deposits to pass stress tests.
• Yield vs. debt cost squeeze: In some cases, net rental income is barely covering mortgage payments — particularly on flats with high service charges.

But it’s not all bad news:

• Northern cities continue to deliver strong rental yields (7%+ in parts of Liverpool, Sunderland, and Newcastle).
• Rents are still rising, especially in family housing and student accommodation.

5. Strategic Considerations for Investors

Given the above, smart investors are adapting:

✅ Lower leverage: Many are scaling back borrowing or going in with cash offers to negotiate better purchase prices.

✅ Targeting higher-yield assets: This includes HMOs, PBSA, and short-term lets in tourism-heavy regions (subject to local restrictions).

✅ Switching to limited companies: For tax efficiency and access to a broader lender pool.

✅ Monitoring rate moves closely: For those on trackers, timing a fixed-rate switch could be critical if rates dip later in 2025.

6. Conclusion & Recommendations

We’re past the panic of 2023, but the era of cheap money is behind us. Rates have stabilised — but remain a major consideration in every deal.

If you’re looking to invest in 2025, it’s time to:

• Re-run your numbers based on 5%+ borrowing costs
• Focus on yield-rich, resilient markets
• Work with brokers to access the right lending structures
