Buy-to-let mortgage rates in the UK are set to get more landlord-friendly in 2026, with the Bank of England base rate already down to 3.75% and more cuts on the horizon. If you’re thinking about snapping up that terraced house in Leeds or a flat in Bristol to rent out, now’s the time to get the lowdown on what rates could look like it could mean the difference between a tidy profit and scraping by.
Why BTL Rates Are Buzzing
Picture this: you’ve got a portfolio of rentals humming along, but those mortgage payments have been a drag since rates spiked a couple years back. Heading into 2026, things are shifting. The base rate’s fresh cut to 3.75% in December 2025 has lenders scrambling to tweak their buy-to-let deals, and experts reckon we’ll see averages dip below 5% for the best fixes. It’s not just numbers on a screen; lower rates mean more cash in your pocket after tenants pay up, letting you expand or just sleep better at night.
Landlords like you have been through the wringer with 6-8% rates in 2024-25, but inflation’s cooling off, and the economy’s stabilizing. Competition’s fierce too over 1,700 limited company BTL fixes available now, up double from two years ago. If you’re remortgaging or buying fresh, 2026 could be your sweet spot before prices climb again.
Base Rate: The Big Driver
Everything starts with the Bank of England. That 3.75% base rate as of late 2025 is the lowest in ages, thanks to inflation behaving itself around target levels. Forecasts say expect another couple of slices maybe to 3.5% by mid-2026, or even 3.25% if growth stays sluggish. The MPC’s playing it cautious, watching wages and spending, but the vibe is downward.
For BTL mortgages, lenders add a premium usually 1.5-3% over base because rentals are riskier than your home loan. Trackers could hug 5-6% total, while fixes price in the drops early. I’ve chatted with brokers who say sub-4% two-year deals are popping up for top-tier landlords already. Keep an eye on February’s meeting; that’s when the next nudge might hit.
Rate Forecasts for 2026
Buckle up, because 2026 looks promising but patchy. Prime two-year fixed BTL rates for individuals or limited companies? Think 4.2-5.5% at 75% LTV, down from today’s 5-6.5%. Five-year fixes might settle at 4.8-6%, great for long-haul holders. HMOs or multis? A tad higher, 4.5-6.5%, but still tasty with demand for family homes booming.
Limited company deals are exploding 74% of portfolios now structured that way for tax perks and rates there start at 4.89% for two-years with fees. Not everything’s rosy; high-risk portfolios or regional buys could stick at 6-8%. Overall, lending’s tipped to grow 2.8%, so more options, but shop smart.
| Deal Type | LTV Max | 2026 Rate Range (Fixed) | Typical Fee | Best For |
| 2-Year Standard BTL | 75% | 4.2% – 5.5% | 1-3% | New purchases, quick flips |
| 5-Year Ltd Co BTL | 75% | 4.8% – 6.0% | £1,495-3% | Portfolio builders, tax savvy |
| HMO/Multi-Unit | 75% | 4.5% – 6.5% | 2-3% | High-yield family lets |
| Remortgage Only | 80% | 4.0% – 5.8% | £995-2% | Existing landlords switching |
Grab this table, punch in your property value, and crunch the monthly cost—it’s a game-changer for decisions.
Fixed or Variable? Your Call
Fixed rates are the safe bet if you hate surprises. Two-year ones could lock at 4.5% for solid applicants, five-years around 5.2%, shielding you from any base rate wobbles. Longer 10-year deals? 5.5-7%, but rare unless you’re ultra-conservative. Variables or trackers? They’re dropping fast, maybe 5% total, and flex with cuts perfect if you reckon rates keep falling.
Fixed pros: Predictable budgeting, peace of mind. Downsides: Miss out if rates tank further. Variables save money short-term but could sting on rebounds. With 20% of BTLs remortgaging in 2026, hybrids like fix-then-switch are hot. Run the numbers on a calculator; what fits your cashflow?
What Shapes Your Rate
Rates aren’t one-size-fits-all. Credit score’s king 700+ gets you the cream. LTV matters big: 75% max for most, but drop to 60% for 0.5% off. Rental income? Lenders want 125-145% coverage of payments, stress-tested at 5.5%. Location plays too London or Manchester prime spots snag better than sleepy suburbs.
Fees bite: 1-3% arrangement, plus £1k+ legals and vals. EPC C or better? Essential now, or kiss lower rates goodbye. Limited companies edge out personal buys on rates but watch corporation tax hikes. Nail your portfolio health, and doors open wide.
