Are fixed-rate buy-to-let mortgage rates likely to fall further following the stable MPC decision, and should I secure a new deal now?
Quick Answer
Fixed-rate buy-to-let mortgage rates might not drop significantly soon, despite stable MPC decisions, as lenders anticipate prolonged higher rates. Securing a deal now can offer stability if your current fix is nearing its end.
## Navigating Buy-to-Let Mortgage Rates in a Stable Market
The UK property market is always moving, and keeping an eye on mortgage rates is crucial for any savvy landlord. With the Monetary Policy Committee (MPC) maintaining the Bank of England base rate at 4.75% as of December 2025, many are wondering if fixed-rate buy-to-let (BTL) mortgage rates will continue their subtle dance downwards, or if now is the time to lock something in. Understanding the nuances requires looking beyond just the base rate.
### Factors Influencing Fixed-Rate BTL Mortgages
* **Bank of England Base Rate Stability:** While the base rate has held at 4.75%, this stability doesn't automatically mean fixed rates will plummet. Fixed rates are more closely tied to 'swap rates', which are essentially the cost for lenders to secure fixed-term funding. These swap rates can react to broader economic sentiment, inflation expectations, and government borrowing, sometimes independently of the immediate base rate. A stable base rate suggests the Bank isn't expecting to make dramatic cuts soon, which might limit how much further swap rates, and therefore fixed rates, can fall.
* **Lender Pricing Strategies:** Lenders operate in a competitive market. They need to balance attracting new business with their own profitability and risk appetite. When swap rates are high, BTL lenders often pass on these costs. We’ve seen typical BTL mortgage rates for 2-year fixes often sitting around 5.0-6.5% and 5-year fixes a little lower, usually 5.5-6.0%. These ranges reflect the current market and lender competition.
* **Market Demand and Supply:** If tenant demand remains strong, property values hold, and rental yields are attractive, lenders will continue to offer BTL products. However, if other factors, like increased regulatory burdens or economic downturns, make BTL less appealing, lenders might tighten criteria or increase rates to mitigate risk.
* **Economic Outlook:** Underlying economic health, inflation forecasts, and employment figures all play a part. If inflation remains stubbornly high, even with a stable base rate, the market might anticipate future rate hikes, which could push swap rates back up. Conversely, a clear path to lower inflation and stable growth could eventually lead to lower swap rates.
### Considerations for Securing a New Deal Now
Given the current landscape, here’s what to weigh up:
1. **Current Rate Levels:** As of December 2025, typical BTL fixed rates range from roughly 5.0% to 6.5%. While they have come down from their peak, dramatic drops aren't currently forecast due to the stable base rate and ongoing economic factors influencing swap rates. For example, on a £200,000 buy-to-let mortgage, moving from a 7% rate to a 5.5% rate would save you approximately £250 per month in interest payments, assuming an interest-only product. This demonstrates the real-world impact of even a 1.5% shift.
2. **Certainty vs. Potential Savings:** A fixed-rate mortgage offers budgeting certainty, protecting you from potential rate increases. If you lock in at 5.5% on a 5-year fix, you know your repayments for that period. Waiting for a small potential drop might expose you to unexpected increases, especially if economic data shifts. The current BTL stress test of 125% rental coverage at a 5.5% notional rate is a good indication of lender caution; they are building in headroom.
3. **The 'New Normal'**: It's important to recognise that the era of ultra-low interest rates may be over. We might be in a 'new normal' where 4-6% fixed rates are more common. Betting on a return to 1-2% fixes could be a gamble.
4. **Application and Legal Fees:** Remember to factor in associated costs. A typical mortgage application might involve a product fee of £999 and valuation fees often around £300-£500. These add up, so ensure any potential savings outweigh these upfront expenses.
## Potential Downsides and Mistakes to Avoid
* **Overlooking Stress Tests:** Lenders use a standard BTL stress test of 125% rental coverage at a 5.5% notional rate. Don't assume your rental income will always meet this if rates rise or you secure a lower fixed rate that then expires into a higher variable rate. Ensure your property cash flows even under higher notional rates.
* **Ignoring Portfolio-Level Impact:** If you have multiple BTL properties, consider the impact on your entire portfolio. A slight uptick in rates could push several properties into negative cash flow if your margins are too tight.
* **Misjudging EPC Requirements:** Don't forget that the minimum EPC rating for rentals is currently E, but there's a proposed change to C by 2030. Mortgages for properties with lower EPCs might become harder or more expensive to secure, regardless of the base rate.
* **Focusing Only on Rate:** While rate is important, also look at the overall package. Are there high product fees? Is the lender slow? Does their criteria suit your specific property type or circumstances?
## Investor Rule of Thumb
Prioritise certainty and robust cash flow; locking in a competitive fixed rate now is often wiser than waiting for marginal drops that may never materialise, protecting your investment from unforeseen market shifts.
## What This Means For You
The decision to fix your mortgage rate involves weighing market projections against your personal risk tolerance and financial stability. Most landlords don't lose money because they make a 'poor' mortgage choice in isolation; they lose money because they make that choice without a full understanding of its impact on their entire property strategy.

Steven's Take
The Bank of England's stable base rate at 4.75% is certainly a welcome reprieve for many, but it doesn't automatically mean we'll see a massive race to the bottom for buy-to-let mortgage rates. Lenders price their products not just on today's base rate, but on their long-term funding costs and what they expect the market to do over the next two, five, or even ten years. They're still pricing in a 'higher for longer' mentality.
My view? If your current fixed deal is coming to an end, or if payment certainty is what you need for your portfolio's cash flow, exploring a new fixed deal now is a sensible play. You can typically secure a rate up to six months before your current one expires, giving you a chance to lock something in without immediate penalty. Don't chase the absolute lowest rate blindly; focus on stability, the overall cost factoring in fees, and how it aligns with your investment strategy. Predictability is power in property.
What You Can Do Next
Review Your Current Mortgage Details: Check your existing mortgage statement for the exact end date of your fixed term and any early repayment charges (ERCs).
Assess Your Personal Financial Needs: Determine how crucial payment stability is for your portfolio's cash flow and your personal financial situation.
Compare Mortgage Products: Approach a specialist buy-to-let mortgage broker. They can compare various lenders' 2-year and 5-year fixed products, including rates, fees, and stress tests, which are typically 125% rental coverage at a 5.5% notional rate.
Consider the Total Cost: Don't just look at the interest rate. Factor in arrangement fees, valuation fees, and any other lender charges to calculate the true cost of the mortgage over the fixed term. For a £200,000 mortgage, a 1% fee adds £2,000.
Act Proactively: If your current deal is ending within six months, you can often secure a new fixed rate in advance, giving you peace of mind and protection against potential future rate rises.
