Lenders Raise BTL Rates: Why Landlords Should Act Now

With Coventry, Nationwide, and Virgin Money raising BTL mortgage rates, David Farmer of Lime Finance Solutions explains why borrowers shouldn’t delay their remortgage.

March 9th, 2026

Fasten your seatbelts… The Buy-to-Let market has hit a sudden patch of turbulence. This week, several of the UK’s major lenders – including Coventry Building Society, Nationwide, Nottingham, and Virgin Money – announced increases to their buy to let mortgage rates.

Triggered by global economic uncertainty and rising swap rates, this shift signals a sharp departure from the downward trend – which was largely expectd to continue throughout this year.

For landlords and property investors with deals expiring in 2026, the message is becoming clear: the era of record-low pricing may be coming to an end. This means that delaying your remortgage could prove to be the more expensive than doing something now.

The Shift in the Market

According to reports from Mortgage Finance Gazette and The Guardian, the recent hikes are a direct response to volatility in the financial markets. Forget base rate, lenders use “swap rates” to price their fixed-rate deals, and as these rates climb, the cost is (wait for it…) passed directly to the borrower.

While the Bank of England had previously been on a path of cutting the base rate, geopolitical events have reintroduced inflationary fears. This has led lenders like HSBC and Nationwide to increase selected fixed rates by as much as 0.25 percentage points.

“There has been a consensus that base rates, and the cost of borrowing, are coming down. All things being equal that may be odds-on, the problem is that things never prove to all be equal” David Farmer

Why Have Swap Rates Moved?

The rapid rise in swap rates in early March 2026 is being driven by a “perfect storm” of geopolitical instability and shifting economic expectations. Excuse me if that sounds like political excuses, but there is truth here. Because swap rates represent the cost at which banks borrow fixed-term funding from one another, they are uber sensitive to any news that suggests interest rates may stay “higher for longer.”

Expert Insight: The Cost of Delay

At Lime Finance Solutions, we are seeing a surge in inquiries from professional landlords concerned about how these rising costs will impact their yields. As important is how these movements will impact the affordability “stress tests” – the calculations lenders use to ensure rental income covers mortgage interest.

David Farmer, founder of Lime Finance Solutions, comments:

“We are entering a cycle where one big-name lender move almost invariably results in others following suit. For landlords, especially those with short-term borrowing maturing this year, the volatility in swap rates is a significant warning. My advice is simple: do not wait for your current deal to expire. By looking at your options early – often up to six months in advance – you can lock in a rate before further hikes take effect. In this market, speed is just as important as the rate itself.”

Why Early Action Matters

Secure Current Pricing: Most lenders allow you to secure a product up to 3 to 6 months before your current deal ends. If rates drop further, you can often switch; if they rise, you are protected.
Affordability Hurdles: Higher interest rates mean tougher “Interest Cover Ratio” (ICR) tests. Acting now might be the difference between qualifying for the loan you need and being forced to inject more capital.
Limited Company Advantages: With over 95% of our BTL lending now going through Special Purpose Vehicles (SPVs), professional structures remain the most efficient way to manage these rising costs.

Summary

The era of “wait and see” is over for 2026. With major lenders already moving their pricing upwards, the advantage lies with the proactive borrower.

FAQ Section

Q: Which lenders have recently raised their Buy-to-Let rates? A: As of early March 2026, Coventry Building Society, Nationwide, Nottingham Building Society, and Virgin Money have all announced or implemented rate increases across their product ranges.

Q: How early can I start my remortgage process? A: Most lenders allow you to secure a new rate up to six months before your current fixed-rate deal expires. This allows you to “hedge” against future rate rises.

Q: Why are rates going up if the Base Rate is low? A: Fixed-rate mortgages are influenced by swap rates (the cost of borrowing between banks). Even if the Bank of England base rate stays the same, swap rates can rise due to global economic uncertainty or inflation forecasts.

Q: Will rising rates affect how much I can borrow? A: Yes. Lenders use a “stress test” to ensure your rent covers the mortgage at a higher interest rate. As rates rise, the amount you can borrow against a specific rental income may decrease.
