A central theme running through the proposals is a clear shift toward more flexible affordability assessments, marking a notable evolution in the regulator’s approach to mortgage lending.
At the heart of the reforms is the FCA’s recognition that current affordability models can be too rigid and may exclude creditworthy borrowers. The regulator is proposing that lenders move away from tick-box affordability checks and instead adopt a more holistic, individualised assessment of a borrower’s financial circumstances.
This includes:
This shift reflects a broader policy direction within the FCA’s Mortgage Rule Review, which aims to rebalance risk and enable the market to better serve modern borrowers without undermining financial stability.
One of the strongest drivers behind the move to flexible affordability is the changing nature of work. Traditional underwriting models often struggle to accommodate:
The FCA’s proposals would allow lenders to take these realities into account more effectively, including offering flexible repayment structures for borrowers with variable income.
By acknowledging that earnings may not always follow a predictable monthly pattern, the regulator aims to ensure that affordability assessments better reflect how people actually earn and manage money today.
The push for flexibility also extends to affordability testing mechanisms. The FCA has previously signalled concern that overly cautious stress testing may be restricting access to mortgages, particularly in a changing interest rate environment.
Lenders are already being encouraged to use the flexibility built into existing rules when assessing future interest rate rises, rather than applying overly conservative assumptions that could block otherwise affordable applications.
In addition, the regulator is reviewing broader constraints such as loan-to-income (LTI) limits, which could further increase lenders’ capacity to offer higher borrowing multiples while maintaining overall market safeguards.
The more flexible approach to affordability is expected to have the greatest impact on certain groups, particularly:
For older homeowners, the FCA is also proposing updated guidance on retirement interest-only (RIO) mortgages, alongside greater flexibility in interest-only products more generally.
These changes aim to support both entry into the housing market and financial flexibility later in life.
While the reforms emphasise flexibility, the FCA has been clear that responsible lending remains a cornerstone of the framework. The proposals build on existing safeguards, including the Consumer Duty, which requires firms to ensure good outcomes for customers.
There is also recognition within the industry that loosening affordability criteria must be handled carefully. Some experts warn that excessive flexibility particularly around interest-only lending or high loan-to-income borrowing could lead to unsustainable debt levels if not properly managed.
As such, the reforms aim to strike a balance widening access while maintaining the resilience of the mortgage market that has been strengthened since the financial crisis.
The FCA has opened a formal consultation on its proposals, inviting feedback from lenders, industry stakeholders and consumers. The consultation runs until 28 July 2026, after which the regulator will consider responses before deciding whether to implement the changes.
Rachael Mitchell, Licensed Conveyancer and Head of Residential Conveyancing at Lawson West, commented:
“If implemented, these changes could unlock home ownership for thousands of borrowers who are currently excluded despite being able to afford mortgage repayments, while still preserving the safeguards needed to protect both consumers and the wider financial system.
However, this flexibility must be applied carefully. The lessons of the past remain firmly in mind, no one wants history to repeat itself with the consequences of excessive high-risk lending, including lending in excess of 100% and the wider instability that ultimately led to bank failures during the financial crisis.
As such, lenders will need to strike a delicate balance between innovation and responsibility, ensuring that increased access does not come at the expense of long term affordability or consumer protection.”
