Three specialist buy-to-let lenders reduced fixed rates in October 2026, with headline two-year pricing now starting below 3.5% and portfolio landlord exposure limits rising sharply. Paragon Bank cut rates by 15 basis points across its Core and Tailored ranges, United Trust Bank reduced two-year fixes by up to 50 basis points, and Rely introduced portfolio landlord discounts of up to 40 basis points. The moves coincide with approaching expiries of fixes taken during the 2021–2022 mini-boom, creating a natural remortgage pipeline for landlords who locked in when rates were substantially lower.
Rate cuts and product structure
Paragon's two-year Green Mortgage rates start at 3.40% for properties with EPC ratings A to C at 75% loan-to-value, with a 5% fee and £500 cashback. The EPC D–E equivalent starts at 3.45%. HMO and multi-unit block rates begin at 3.55% with the same fee structure, or 4.55% with a 3% fee, or 6.05% with no product fee. Five-year Green Mortgage rates at 75% LTV start from 4.80%, rising to 4.85% for lower-rated properties and 4.95% for HMOs and MUBs, with a 5% fee and £1,000 cashback.
UTB's standard two-year fixed rates now start at 3.89%, with HMO and multi-unit freehold block products available from 4.04%. Five-year rates remain at 5.69% for standard properties and 5.99% for specialist cases. Rely's limited-edition products for landlords with 11 or more properties carry a 5% fee at 75% LTV and are priced up to 40 basis points below its standard range. New products at 60% and 65% LTV offer discounts of up to 15 basis points for landlords with four or more mortgaged properties.
The fee structures matter more than the marketing suggests. A landlord comparing Paragon's 3.55% HMO rate with a 5% fee against the 6.05% nil-fee option faces a £10,000 upfront cost on a £200,000 loan. The breakeven depends on holding period and the likelihood of early repayment, with fixed-fee and nil-fee alternatives creating different risk profiles for landlords uncertain about portfolio strategy over the next two to five years.
Portfolio appetite and specialist criteria
UTB raised its maximum portfolio landlord exposure to 10 buy-to-let loans and £3 million per applicant, up from undisclosed prior limits. The lender also removed previous ownership experience requirements for HMO and MUFB applications, lowering the barrier for landlords moving into higher-margin specialist property. The combination of increased exposure and relaxed criteria suggests lenders are competing for scale landlords as a segment, not simply responding to rate pressure.
The risk is concentrated but the underwriting cost is justified by yield. Portfolio landlords with complex ownership structures, mixed property types and higher loan balances generate more fee income and attract less price sensitivity than single-property investors. UTB's move to £3 million per applicant signals confidence that the professionalised landlord segment can support higher leverage without proportionate default risk, particularly where HMO and MUB properties generate rental premiums over standard BTL stock.
No detail has been provided on stress testing, affordability criteria or interest coverage ratio requirements, which may offset headline rate competitiveness. Lenders tightened ICR thresholds substantially after Section 24 restricted mortgage interest relief, and any divergence in affordability calculations will determine which landlords can access these rates in practice. Brokers should confirm stress rates and minimum ICR before presenting these products as directly comparable.
EPC pricing and retrofit economics
Paragon's five-basis-point differential between EPC A–C and D–E properties at 75% LTV translates to approximately £10 per month on a £200,000 loan. The saving is immaterial against the capital cost of retrofitting a D-rated property to C or above, which typically ranges from £5,000 to £15,000 depending on measures required. The pricing gap functions as a minor acquisition incentive rather than a retrofit driver, rewarding landlords who buy compliant stock rather than those who improve existing holdings.
The structure anticipates regulatory tightening without creating commercial pressure to act. If minimum EPC standards move from E to C for new tenancies, the rate differential positions Paragon to re-price non-compliant stock more aggressively without introducing a new product. For now, the gap is too narrow to change landlord behaviour but wide enough to establish the principle of EPC-linked pricing in the BTL market.
