Mortgage Affordability in 2026: What Has Changed

The Bank of England base rate in context

The Bank of England base rate is the single most influential factor in UK mortgage pricing and, by extension, affordability. To understand where we are in 2026, it helps to trace the trajectory over the past few years.

In December 2021, the base rate was just 0.25%, having been held at historically low levels throughout the COVID-19 pandemic. The Bank of England then began a rapid series of increases in response to rising inflation, reaching a peak of 5.25% in August 2023. This was the highest base rate since 2008 and represented a dramatic shift for borrowers who had become accustomed to ultra-low rates.

The rate-hiking cycle ended in late 2023, and the first cut came in August 2024 when the Monetary Policy Committee (MPC) voted to reduce the base rate to 5.0%. Further gradual cuts followed through late 2024 and into 2025 as inflation trended back towards the 2% target.

As of September 2026, the base rate stands at 3.75%, where it has been held since December 2025. At the 17 September 2026 meeting the MPC voted 6–3 to hold, with three members preferring a rise. Meanwhile swap rates, which lenders price fixed deals off, have been rising, and lenders including HSBC, Barclays, NatWest, Santander have repriced fixed deals upwards. The next decision is due on 5 November 2026. The era of near-zero interest rates appears firmly in the past.

The 2022 affordability test removal and its impact

In August 2022, the Bank of England's Financial Policy Committee (FPC) withdrew the mortgage affordability stress test that had been in force since 2014. This test required lenders to assess whether borrowers could afford mortgage payments if the base rate rose by 3 percentage points above the lender's standard variable rate (SVR).

The removal was significant in principle but modest in practice. The FPC concluded that the separate FCA affordability rules and the loan-to-income (LTI) flow limit together provided sufficient protection against over-lending. With the LTI limit restricting no more than 15% of new mortgage lending at 4.5x income or above, the affordability stress test had become, in the FPC's view, the less binding of the two constraints.

In the years since removal, the impact has been nuanced:

• Greater lender divergence. Without a common stress test floor, lenders have more freedom to set their own stress rates. This has increased the variation in maximum borrowing between lenders, making it more important than ever to check multiple lenders.
• Marginal increase in maximum lending. Some lenders increased their maximum multiples or reduced their stress rates slightly after the removal, allowing certain borrowers to qualify for modestly higher amounts.
• LTI limit remains the constraint. For many borrowers, particularly those on average incomes seeking to buy in high-value areas, the 4.5x LTI limit -- not the stress test -- is what prevents them from borrowing more. The removal of the affordability test did not change this constraint.

How stress rates have evolved

Lender stress rates are the internal rates used to test whether borrowers can afford their mortgage payments in a higher-rate environment. Since the removal of the FPC stress test, each lender sets its own rate, and the variation across the market has widened.

During the peak of the rate-hiking cycle in 2023, many lenders had stress rates of 8% to 9%. With product rates at 5% to 6% and the base rate at 5.25%, these stress rates implied a relatively narrow buffer above actual rates. Despite this, they still constrained borrowing significantly because the absolute level was so high.

As the base rate fell through 2024 and 2025, stress rates generally declined too, but not by the same magnitude. As of 7 September 2026, typical stress rates range from about 7–8.5%. The gap between stress rates and product rates has actually widened at some lenders, creating a larger buffer.

This matters for borrowers because a lender with a 7% stress rate will offer meaningfully more than one with an 8.5% stress rate, even if both offer the same product interest rate. On a 25-year repayment mortgage of £250,000, the difference in stressed monthly payments between 7% and 8.5% is over £240 per month, which translates to a significant difference in maximum borrowing.

Stress rates tend to follow product rates, with a lag. With Bank Rate on hold and lenders repricing fixed deals upwards, further reductions look less likely in the near term.

Current mortgage product rates

Mortgage product rates in 2026 are below their 2023 peak, though they remain well above the sub-2% levels seen in 2021, and lenders have recently been repricing fixed deals upwards. The key benchmarks as of 7 September 2026 are approximately:

• 2-year fixed rates: market average around 5.63%, with the most competitive large-deposit deals meaningfully lower (best-buys around 4.3–4.6%)
• 5-year fixed rates: market average around 5.68% — still pricing a touch above 2-year fixes
• Tracker rates: base rate + 0.5% to 1.5% (approximately 4.25% to 5.25%)
• Standard variable rates (SVRs): roughly 6.3–8.4%, averaging around 7.1%

Fixed rates are priced off swap rates rather than Bank Rate directly. As of 3 September 2026, the 2-year swap was 4.26% and the 5-year 4.36% (up from 4.06% and 4.16% a month earlier, per Moneyfacts), which is why fixed pricing can rise while Bank Rate is held.

For affordability purposes, what matters most is not the product rate you will actually pay, but the stress rate the lender applies when assessing your application. Even if your product rate is 4%, the lender may stress-test at 7%, and it is this higher rate that determines how much you can borrow.

Rates vary significantly by loan-to-value (LTV) ratio. Borrowers with larger deposits (60% LTV or lower) typically access the best rates, while those at 90% or 95% LTV pay a premium. The difference between a 60% LTV and 95% LTV rate can be 0.5% to 1.0%, which affects both monthly payments and the stress test outcome.

Current lending trends

Several trends in UK mortgage lending in 2026 are worth noting for borrowers assessing their affordability:

Longer mortgage terms. Mortgages with terms of 30 to 35 years have become increasingly common, particularly among first-time buyers. A longer term reduces the monthly payment (and the stressed monthly payment), which means borrowers can qualify for larger loans. However, the total interest paid over the life of the mortgage increases substantially. Some lenders now offer terms up to 40 years, though most cap at 35 years or require the mortgage to be repaid by age 70 or 75.

Professional multiples. An increasing number of lenders offer enhanced income multiples (up to 5.5x or 6x) for borrowers in specific professions. Doctors, dentists, solicitors, chartered accountants, and veterinary surgeons are commonly included. These enhanced multiples are typically available only with a minimum deposit of 10% to 15%.

Green mortgages. Lenders are increasingly offering rate discounts or enhanced borrowing for energy-efficient properties. Homes with an EPC rating of A or B may qualify for lower interest rates, reflecting the lower running costs (and therefore higher disposable income) associated with energy-efficient homes.

Joint Borrower Sole Proprietor (JBSP) mortgages. These products allow a parent or family member to be included on the mortgage application (boosting affordability with their income) without being named on the property title. This helps first-time buyers who cannot afford a property on their own income. Several major lenders and building societies now offer JBSP products.

95% LTV lending. Freedom to Buy — the permanent mortgage guarantee scheme that replaced the temporary Mortgage Guarantee Scheme in July 2025 — continues to support 95% LTV lending on homes worth up to £600,000. While the scheme provides a government guarantee to lenders, the affordability assessment for 95% LTV borrowers remains stringent. Borrowers at this LTV typically face higher product rates and may be restricted to lower income multiples.

First-time buyer schemes still available

Several government and industry schemes remain available to help first-time buyers in 2026:

Freedom to Buy (permanent mortgage guarantee scheme). Launched in July 2025 as the permanent successor to the Mortgage Guarantee Scheme, Freedom to Buy encourages lenders to offer 95% LTV mortgages by providing a government guarantee on a portion of the loan. It applies to primary residences worth up to £600,000 with a deposit of 5% to 9%. It is not a direct subsidy to borrowers, but it has improved the availability of high-LTV products from major lenders.

Shared Ownership. Available through housing associations, Shared Ownership allows you to buy a share of a property (from 10% under the current model, up to 75%) and pay rent on the remainder. The mortgage is only on the share you purchase, making the affordability requirement more manageable. Eligibility is based on household income — £80,000 or less outside London, £90,000 or less in London — rather than a property price cap.

Lifetime ISA (LISA). First-time buyers aged 18 to 39 can save up to £4,000 per year into a LISA and receive a 25% government bonus (up to £1,000 per year). The funds can be used towards a first home worth up to £450,000. The bonus and savings contribute to your deposit, which indirectly improves affordability by reducing the LTV ratio.

First Homes scheme. This scheme offers new-build homes to local first-time buyers at a discount of at least 30% below market value. The discount is passed on to future buyers, keeping the homes affordable in perpetuity. Availability is limited to participating developments.

Help to Buy: ended in England, open in Wales. The Help to Buy equity loan scheme in England closed to new applications in October 2022, with completions ending in March 2023. Existing Help to Buy equity loans continue, with borrowers needing to repay the government's equity stake when they sell or at the end of the loan term. Help to Buy – Wales remains open to new applications until 31 March 2027.

New Build Boost (England). Gen H's New Build Boost lets buyers of new-build homes from selected builders (including Persimmon, Charles Church and Lovell) put down a 5% deposit, take an 80% mortgage and cover the remaining 15% with an interest-free equity loan. It is available in England only, not in Scotland or Wales.

Stamp Duty Land Tax relief. First-time buyers in England and Northern Ireland pay no SDLT on the first £300,000 of a property priced up to £500,000. Above £300,000 (up to £500,000), the rate is 5%. This relief reduces the upfront costs of buying, potentially allowing more of your savings to go towards the deposit.

What to expect going forward

Predicting future interest rates and lending trends is inherently uncertain, but several factors are likely to shape mortgage affordability through the remainder of 2026 and beyond:

Bank Rate is on hold. The base rate has been held at 3.75% since December 2025. At the 17 September 2026 meeting the MPC voted 6–3 to hold, with three members preferring a rise, so further cuts cannot be taken for granted. The next decision is due on 5 November 2026; our rates update explains what each outcome would generally mean.

Fixed rates are being repriced upwards. Fixed rates are priced off swap rates (the market's expectation of future interest rates), not Bank Rate directly. Swap rates have risen over the past month, and lenders including HSBC, Barclays, NatWest, Santander have raised fixed-rate pricing (reported by Moneyfacts / Mortgage Solutions, 7 September 2026). Product rates can rise even while Bank Rate is unchanged.

Lender stress rates are unlikely to ease soon. Stress rates tend to lag product rates. While fixed pricing is rising, lenders are unlikely to cut their stress test rates; any future reduction would directly increase the amount borrowers can qualify for.

The LTI limit is being consulted on. Since July 2025 the PRA has offered lenders interim flexibility around the 15% cap, and in April 2026 it published a consultation (CP6/26) proposing to remove the firm-level limit entirely in favour of a more principles-based approach. Final rules are expected in the second half of 2026; until then the limit technically remains in force and continues to cap borrowing for many applicants, particularly where house prices are high relative to local incomes.

Lenders still compete on criteria. Even while fixed-rate pricing is rising, lenders compete for mortgage business through more accommodating criteria for income assessment, expenditure treatment, and eligibility rules. This competitive dynamic is another reason why checking multiple lenders is valuable -- the landscape shifts regularly.

The overall picture for mortgage affordability in 2026 is cautiously positive. Borrowers can generally qualify for more than they could at the peak of the rate cycle in 2023-2024, though rising fixed-rate pricing means further improvement is not guaranteed in the near term. Affordability remains tighter than during the ultra-low rate era, and borrowers should be realistic about the amounts they can sustain, not just what they can qualify for.
