Best buy to let mortgage lenders in 2026 best buy to let mortgage lenders

The UK buy to let mortgage market is served by a mix of high street banks, building societies, and specialist lenders. Each targets different types of landlord, so the best lender for you depends on your property portfolio, how you structure ownership, and the type of property you are buying.

The major lenders in this space include:

• BM Solutions: The buy to let arm of Lloyds Banking Group and one of the largest BTL lenders in the UK. Known for competitive rates on standard buy to let purchases and remortgages, with a straightforward application process through brokers only.
• The Mortgage Works (TMW): Owned by Nationwide Building Society. Offers some of the lowest rates in the market, particularly on 5-year fixed deals. Accepts applications for both personal and limited company purchases.
• Paragon Bank: A specialist BTL lender with a strong track record serving portfolio landlords. One of the few lenders that actively welcomes applicants with four or more mortgaged properties.
• Aldermore: Caters to landlords who don't fit standard high street criteria, including first-time landlords without residential mortgage history, complex income structures, and ex-pat landlords.
• Precise Mortgages: Specialist lender handling more complex scenarios such as HMOs, multi-unit freehold blocks, and applicants with minor credit blips.
• Landbay: Technology-driven lender focused exclusively on buy to let. Competitive on limited company lending with fast decision times.

Buy to let mortgage rates vary significantly between lenders and depend on your loan-to-value ratio, whether you are buying personally or through a company, and the fixed rate term you choose. As of mid-2026, the Bank of England base rate sits at 3.75%, and competitive buy to let rates start from around 3.9% for the best 5-year fixed deals at 60% LTV.

Most landlords will find rates between 4.0% and 5.5% depending on their circumstances. Limited company buy to let rates are typically 0.3-0.5% higher than personal rates. Shorter fixed terms (2-year fixes) tend to carry slightly higher rates than 5-year deals in the current market, reflecting expectations of future base rate reductions.

These rates are indicative and change frequently. The cheapest rate is not always the best deal once you factor in arrangement fees, which range from free to over £2,000. A slightly higher rate with no arrangement fee can work out cheaper over a 2-year term than a headline-grabbing low rate with a £1,995 fee. Use a buy to let mortgage calculator to compare total costs across different deals.

Choosing the right buy to let lender involves more than comparing headline rates. Different lenders have different criteria for rental coverage, income requirements, and property types. Getting this wrong means wasted applications and unnecessary credit searches on your file.

Key factors to consider when comparing lenders:

• Rental coverage ratio: Most lenders require the expected rent to cover 125-145% of the mortgage payment at a stress test rate (typically 5.5%). Some lenders use lower stress rates, which lets you borrow more on the same rental income.
• Minimum income: Some lenders require a minimum personal income of £25,000, while others have no minimum income requirement. This matters if you plan to be a full-time landlord or have a lower income.
• Property type: Standard houses and flats are accepted by most lenders. HMOs, multi-unit freehold blocks, and properties above commercial premises need specialist lenders.
• Landlord experience: Some lenders offer their best rates only to experienced landlords. First-time landlords may face slightly higher rates or stricter criteria with certain lenders.
• Age limits: Maximum age at end of term varies from 75 to 85 years depending on the lender. Some specialist lenders have no upper age limit.

Buying through a special purpose vehicle (SPV) limited company has become increasingly popular since the Section 24 tax changes phased out mortgage interest relief for higher-rate taxpayers. Most major buy to let lenders now accept limited company applications, though rates tend to be slightly higher than personal purchases.

The lenders offering the strongest limited company buy to let products include:

• Landbay: Built specifically for SPV lending with competitive rates and fast processing. One of the most popular choices for limited company landlords.
• The Mortgage Works: Accepts newly incorporated SPVs with competitive rates close to their personal BTL products.
• Paragon Bank: Strong on limited company lending for portfolio landlords, with no limit on the number of properties held within the company.
• Kent Reliance: Flexible criteria including acceptance of complex company structures and multiple directors.

When applying through a limited company, lenders typically require personal guarantees from all directors and shareholders with 20%+ ownership. The company must have SIC codes 68100 (buying and selling own real estate) or 68209 (other letting and operating of own or leased real estate). Most lenders want the company set up as an SPV rather than a trading company.

Since the Prudential Regulation Authority introduced tighter rules in 2017, landlords with four or more mortgaged properties face additional scrutiny from lenders. Many high street banks withdrew from this market, but several specialist lenders actively welcome portfolio landlord applications.

Lenders that specialise in portfolio landlord mortgages include Paragon Bank, The Mortgage Works, Aldermore, Precise Mortgages, and Kent Reliance. These lenders assess your entire portfolio rather than just the individual property being mortgaged. They look at total borrowing, overall rental coverage, and the spread of your portfolio across different property types and locations.

What portfolio landlord lenders typically require:

• Full portfolio schedule: Details of every property, its value, mortgage balance, monthly payment, and rental income
• Overall rental coverage: Total portfolio rental income must cover total mortgage payments by at least 125% at the stress test rate
• Business plan: Some lenders want to understand your acquisition strategy and property management approach
• Experience: Most require at least 12 months as a landlord, though some accept first-time portfolio applicants with strong financials

A specialist buy to let broker is particularly valuable for portfolio applications. They can structure your application to meet the specific requirements of each lender and ensure your portfolio schedule is presented correctly.
