This offering is ideal for clients who don’t meet traditional lending criteria, such as the self-employed, contractors, or those with irregular income or a history of credit issues.
Why Kensington’s 40-Year Fixed-Rate Mortgage Matters

Kensington Specialist Lender Launches Flexi Fixed for Term Mortgage
Kensington Mortgages, a leading specialist mortgage lender in the UK, has introduced an innovative solution designed for today’s complex borrowers. Backed by funding from Rothesay, a specialist pensions insurer, this new long-term fixed-rate mortgage meets the growing demand for payment certainty and flexible lending criteria.
Homeowners Prefer Certainty: Why Long-Term Fixed Rates Matter
According to recent research from Kensington Mortgages, 83% of UK homeowners and renters would prefer a long-term fixed-rate mortgage. This strong preference reflects a rising demand for predictable monthly repayments and long-term financial stability.
In response, Kensington has partnered with Rothesay to launch a mortgage product offering fixed interest rates for up to 30 years, providing borrowers with peace of mind in an unpredictable economy.
Competitive Rates Across Loan Terms
The new Flexi Fixed for Term product offers competitive rates tailored to a range of borrower needs. Available for both home purchases (up to 95% LTV) and remortgages (up to 85% LTV), this product provides clients with stability without sacrificing value.
Sample Interest Rates at 60% LTV:
-
15-year term: 2.83%
-
25-year term: 2.85%
-
30-year term: 2.90%
Higher LTV Options (95%):
-
25-year term: 3.71%
-
30-year term: 3.77%
These rates are competitive in the market, particularly for borrowers seeking long-term fixed mortgages with flexible underwriting.
Greater Affordability Through Smarter Lending
Unlike traditional mortgage affordability models that rely on high stress test rates, Kensington’s Flexi Fixed for Term uses the actual fixed interest rate to assess affordability. This modern approach often enables clients, especially the self-employed or those with irregular income streams, to borrow more than they could with a standard lender.
This data-driven approach exemplifies Kensington’s role as a specialist lender, offering intelligent underwriting, ideal for clients who may not meet the rigid criteria of high-street banks.
Built-in Flexibility for Changing Circumstances
One of the standout features of this mortgage is its portability. Borrowers can move home without changing their interest rate or monthly repayment, offering crucial flexibility in a shifting housing market.
Additional benefits include:
-
No product fees and free legal services
-
No early repayment charges in cases of property sale, critical illness, or death
-
Up to 10% overpayments annually based on the original loan amount
-
Further advances available after 12 months, subject to affordability
Broker Benefits and Network Support
Kensington supports advisers and brokers with a 0.75% proc fee on completion, making this an attractive proposition for mortgage clubs and networks.
If you’re part of a Specialist Mortgage Network for Advisers, this product can help you serve clients with non-standard profiles more effectively.

Expert Insight on Kensington’s Innovative Mortgage Products

Mark Arnold, CEO of Kensington Mortgages, explains the shift in borrower sentiment amid changing interest rate trends:
“For over a decade, ultra-low interest rates have shaped homeowner expectations. But as the market moves toward more traditional averages, we anticipate gradual rate increases becoming the new normal. In this evolving environment, long-term stability is more important than ever.
That’s why products like our Flexi Fixed for Term mortgage, already common across parts of Europe, are gaining traction in the UK. They offer borrowers a single fixed monthly payment that never changes for the entire life of the loan.
This isn’t just about stability. It’s about flexibility and accessibility. Whether you’re a first-time buyer, a self-employed professional facing remortgage challenges, or simply looking to lock in predictable payments, this mortgage was built to meet diverse needs.
While a long-term fixed mortgage won’t suit everyone, we’ve engineered the Flexi Fixed for Term to provide maximum flexibility. For many, it could be the key to finally stepping onto the property ladder.”
Mortgage Affordability Challenges: What Kensington Found
Recent research from Kensington specialist lender reveals key hurdles for aspiring homeowners:
-
1 in 4 renters who tried to buy in the last five years were unsuccessful.
-
Among them, over 20% failed affordability checks.
-
Nearly a quarter couldn’t borrow enough to purchase a suitable property.
These findings underscore the value of flexible lending products. Kensington’s innovative offering is designed to help underserved segments, such as freelancers, contractors, and those with thin credit profiles, access long-term, sustainable financing.
