Buy-to-let mortgage rates have been moving every week since the Bank of England's base-rate path stabilised in early 2026. The headline number lenders advertise is rarely the number a landlord actually ends up paying, it depends on product fees, fix length, LTV, stress test, and structure. This guide cuts through the noise.
What follows is what the specialist BTL panel is actually pricing in May 2026, by product and structure, with the lender-side context on why each rate sits where it does. Figures are indicative and refresh weekly; for a live rate on your specific case, book a 15-minute call with the broker desk.
Across the 100-plus specialist BTL lender panel, indicative pay rates in mid-May 2026 cluster as follows:
| Product | 2-year fix | 5-year fix | Tracker |
|---|---|---|---|
| Standard BTL · 60% LTV | 5.05-5.45% | 4.95-5.25% | BBR + 1.5-2.0% |
| Standard BTL · 75% LTV | 5.45-6.20% | 5.25-5.85% | BBR + 1.9-2.5% |
| Limited company SPV · 75% LTV | 5.75-6.45% | 5.55-6.15% | BBR + 2.1-2.7% |
| HMO mortgage · 75% LTV | 5.95-6.85% | 5.75-6.55% | BBR + 2.3-3.0% |
| Holiday let · 75% LTV | 6.25-7.20% | 5.95-6.85% | BBR + 2.5-3.3% |
| Bridge-to-let bridge tranche | 0.55-0.95% per month + 1.5-2.5% arrangement fee | ||
Two structural points to read alongside this table. First, lower LTV gets you a meaningfully better rate. The 5-year fix at 60% LTV is sometimes 75-100 basis points cheaper than the same fix at 75% LTV, on a £300,000 loan over five years, that can mean £11,000+ of interest saved before the product fee is even considered. If you have the deposit headroom and your yield maths still works at the lower LTV, take it.
Second, the cheap rates have hefty product fees attached. A 4.95% headline rate often comes with a £1,995-£3,995 product fee, or a percentage-based fee of 1-3% of the loan. We always model the rate alongside the fee structure on a true-cost basis, the apparently-cheaper product is sometimes the more expensive one on a 5-year hold.
Behind every BTL mortgage decision sits a stress test. Lenders calculate the rental cover ratio (ICR) by stressing the loan at a notional interest rate, typically 5.5%, against your monthly rent. For a higher-rate landlord, the ICR threshold is usually 145%, meaning your rent must cover 145% of the stressed monthly interest. Limited-company SPV and basic-rate borrowers get the more forgiving 125% ICR.
The structural quirk is that lenders are permitted to apply a softer stress on 5-year fixed products. Instead of stressing at 5.5%, many will stress at the pay rate of the product itself (around 5.25-5.49% in May 2026). That small difference compounds into a meaningfully higher maximum loan.
Worked example, higher-rate landlord, £1,500 monthly rent:
The same rent, three different maximum loans. The SPV structure on a 5-year fix unlocks roughly 16% more borrowing than the personal-name 2-year fix, which is often the difference between a deal that works and one that doesn't.

Three forces are pulling on BTL pricing this year, and they're pulling in different directions.
Bank of England base rate. The BoE held base rate at 4.25% through the first half of 2026 after the rate-cut cycle stalled. Tracker products move directly with this; fixed products bake in expectations of future moves via the swap curve. Markets are currently pricing one further 25bp cut in late 2026, which is why 2-year fixes sit only marginally above 5-year fixes, the swap curve is broadly flat.
Specialist BTL lender competition. The challenger and specialist lender pool (Paragon, Landbay, Foundation, Kent Reliance, Fleet, Aldermore, The Mortgage Works, Shawbrook, Together) has been aggressive on price in 2026 as deposit flows allowed them to undercut high-street BTL pricing. The widest competition is at 75% LTV with 5-year fix, especially for limited-company SPV cases, exactly where the volume of new lending sits.
Funding cost differential by lender type. High-street lenders (Barclays, NatWest, HSBC, Halifax, Lloyds, Nationwide) fund cheaply via deposits but are picky on BTL underwriting. Specialist lenders fund via securitisation and wholesale markets, slightly more expensive cost-of-funds but materially more flexible on case shape. That's why a Barclays product might be 25bp cheaper than a Paragon product on the headline but Paragon will take cases Barclays won't even quote on.
The rate quoted on a comparison site is rarely the cost. A 4.95% headline often carries:
Our fee model is straightforward and aligned: we charge 1% of the loan amount, only payable on successful drawdown. The procuration fee paid by the lender is taken first against that 1%; you only pay the difference where the lender's proc fee is below 1%. On a typical £200,000 BTL with a 0.45% lender proc fee, that means roughly £900 from the lender and £1,100 from you, capped at £2,000 total. No fee at all if the case does not complete.
On a £200,000 BTL mortgage, the difference between a 4.95% rate with a £3,995 product fee and a 5.45% rate with no product fee can be £4,000-£6,000 over a 5-year hold once you factor in the fee being added to the loan and accruing interest. The headline-rate winner is sometimes the true-cost loser. We model this on every case.
A non-exhaustive snapshot of who's competitive in May 2026, by segment:
The lowest rate available on your case depends on inputs you can influence (deposit, structure, fix length, evidence pack) and inputs you can't (your credit profile, the property type, current market). The biggest wins are typically:
