Should I wait for further mortgage rate cuts, or fix my buy-to-let mortgage now with Skipton or Leek BS?
Quick Answer
With the Bank of England base rate at 4.75% and BTL fixed rates between 5.0%-6.5%, waiting for further cuts carries risk; fixing now provides payment stability for your buy-to-let mortgage.
## Mortgage Stability vs. Market Swings
Fixing a mortgage rate offers the certainty of knowing your monthly payments for a set period, typically 2 or 5 years for buy-to-let (BTL) products. For example, a landlord securing a 5-year fixed rate mortgage at 5.5% on a £200,000 BTL loan would have predictable payments, unaffected by base rate fluctuations for that duration. This stability is particularly valuable for precise cash flow forecasting and managing rental yield calculations, which can be critical for BTL investors. However, if interest rates fall during the fixed term, the landlord will not benefit from those lower rates until the fixed period ends. Conversely, if rates rise, the fixed rate protects the landlord from increased costs.
## Potential Downsides of Waiting for Rate Cuts
Waiting for potential mortgage rate cuts means you remain on a variable rate, which could increase if the Bank of England base rate rises. As of December 2025, the base rate is 4.75%. While there is market speculation about future movements, there is no guarantee rates will fall further; they could just as easily rise. For instance, if you're currently on a variable rate at 6.0% and the base rate increases by 0.5%, your payments would likely increase. This uncertainty directly impacts your buy-to-let profit margins and can make financial planning difficult. Additionally, an increase in borrowing costs can affect a property's Investment Cash Return (ICR) stress test, making it harder to refinance or acquire additional properties if rates move unfavourably.
## Does this affect all buy-to-let properties?
The decision to fix or wait impacts all mortgaged BTL properties where the lender offers fixed-rate products. The standard BTL stress test requires rental coverage of 125% at a notional rate, usually around 5.5%. If you are on a variable rate, and that rate moves above 5.5%, your property's ability to cover the mortgage interest (ICR) could be challenged, or future lending could be impacted. Skipton and Leek BS, as well as other lenders, predominantly offer fixed-rate products for BTL investors for periods like 2 or 5 years, providing this payment certainty. The decision does not impact properties owned outright as there is no mortgage. Similarly, if your current fixed rate has many years left, this immediate decision is not relevant.
## How does the current lending environment factor in?
The current lending environment, with typical BTL mortgage rates ranging from 5.0-6.5% for 2-year fixed and 5.5-6.0% for 5-year fixed products, reflects the Bank of England's current base rate of 4.75%. Lenders build in a margin and factor in market expectations. For example, a £250,000 buy-to-let mortgage at 5.5% would mean a monthly interest-only payment of £1,145.83. A reduction of even 0.25% would save £52.08 per month, or £625 annually. However, any rate decrease is not guaranteed. Mortgage products are also subject to specific lender criteria, such as minimum income, portfolio size, and property type, which influence the rates offered. Understanding the total cost of borrowing, not just the headline rate, including arrangement fees and early repayment charges, is part of prudent financial planning for your buy-to-let investment journey.
## Investor Rule of Thumb
Prioritise financial certainty and cash flow stability for your buy-to-let portfolio, rather than gambling on unpredictable future interest rate movements.
## What This Means For You
Most landlords don't lose money because they fix their mortgages at a reasonable rate, they lose money because they expose their portfolio cash flow to unnecessary risk by not fixing.

Steven's Take
The core of this decision is simple: certainty versus speculation. With the base rate at 4.75%, typical BTL fixed products are coming in at 5.0-6.5%. If you fix now, you lock in your costs, which is invaluable for a property investor. Waiting for cuts means you’re betting against potential base rate increases, and against lender margins. I always favour predictable cash flow over chasing a slightly lower rate that might not materialise. Your BTL investment goals should be built on stability, not market predictions. Consider the stress test implications; maintaining that 125% rental coverage at 5.5% notional rate is easier with a fixed payment.
What You Can Do Next
Step 1: Review your current mortgage terms - Identify your existing rate, lender, and the end date of any fixed term. Check any early repayment charges (ERCs) if you were to remortgage now.
Step 2: Compare current BTL fixed rates - Obtain explicit quotes from Skipton, Leek BS, and other BTL lenders for 2-year and 5-year fixed products. Use independent mortgage brokers who specialise in buy-to-let to ensure you see the full market.
Step 3: Conduct a cash flow analysis - Calculate your current monthly profit/loss with your existing mortgage, and then project it with the newly quoted fixed rates. Factor in all costs including the 5% additional dwelling Stamp Duty for new purchases and the 24% CGT for higher rate taxpayers if considering sales, to understand the net impact.
Step 4: Consult a financial advisor - Speak to an independent financial advisor or mortgage broker who understands the buy-to-let market to discuss your risk tolerance and long-term financial goals.
