Foundation Expands BTL Offering with New Products and Lower Rates in 2026

As of May 2026, Foundation has expanded its Buy-to-Let (BTL) offering with the launch of several new products and a reduction in BTL rates. These changes include a new green standard HMO product, five-year fixes for MUFBs and holiday lets, and a two-year fix for expat borrowers, all with competitive rates and fees.

Details of the New BTL Products

Foundation’s green standard HMO product is priced at 5.59% with a 4% fee. It comes with £500 cashback, no application fee, and is open to properties with an Energy Performance Certificate (EPC) rating of A to C. For MUFBs and holiday lets, Foundation has introduced a pair of five-year fixes, each with a flat fee of £4,995. The MUFB product is priced at 6.24% and the holiday let option at 6.34%. For expat borrowers, a two-year fix has been added to the F2 range, priced at 6.34% with a 1.5% fee. Within its F1 range, for borrowers with an almost clean credit history, a green five-year fix has been launched at 5.49% with a 5% fee.

Impact on Borrowers

Scenario 1: Landlord with a Green Standard HMO

A landlord with a £250,000 interest-only BTL mortgage for a green standard HMO at 75% LTV would see their monthly cost drop from £1,432 to £1,389 due to the new rate of 5.59%. This equates to a saving of £43 per month or £516 per year.

Scenario 2: Expat Borrower with a Two-Year Fix

An expat borrower with a £200,000 repayment mortgage at 75% LTV would see their monthly payments drop from £917 to £875 with the new two-year fix rate of 6.34%. This results in a saving of £42 per month or £504 per year.

Market Context

These changes come at a time when the Bank of England base rate is 3.75%, having increased from 3.5% six months ago. The new rates offered by Foundation are competitive in the current market, particularly for landlords and expat borrowers. The introduction of green products also aligns with the increasing focus on energy efficiency in the UK property market.
