UK homeowners are currently confronting what one leading mortgage expert describes as the single greatest threat to their finances — and it may not be what they expect.
The warning comes as the Bank of England has revealed that approximately 1.3 million additional households now face rising mortgage costs following economic turbulence triggered by the Middle East conflict.
According to the central bank's latest financial stability report, Britain's economic outlook has worsened, placing mounting strain on both households and businesses across the country.
The conflict has driven up energy prices whilst pushing mortgage rates higher, creating a perfect storm for property owners approaching the end of their fixed-rate deals.
With lenders withdrawing products and repricing rapidly, the question of timing has become critical for millions of borrowers navigating an increasingly unpredictable market.
Sam Kirtikar, chief executive of The Mortgage Broker, identifies the primary danger facing homeowners as something within their control: putting off seeking professional guidance.
He told GB News: "The single biggest risk right now is delaying independent advice. In a fast-moving market, waiting too long to review your options can mean losing choice, missing a suitable rate or being forced into a decision under pressure later on."
However, he stressed this does not mean borrowers should rush into hasty decisions. Instead, those with a remortgage deadline approaching within six to seven months should begin exploring their options now.
Mr Kirtikar cautioned against simply using a lender's mobile app to switch rates without comparing the wider market, warning that homeowners who take this shortcut could overlook significantly more cost-effective alternatives available elsewhere.
The key, he emphasised, is obtaining early advice to make informed choices within an appropriate timeframe.
Approximately 86 per cent of UK mortgages are currently on fixed-rate terms, Government figures indicate | GETTYThe scale of market turbulence has been stark. Over the past three weeks, mortgage lenders have withdrawn products and adjusted rates with less than 24 hours' warning, leaving advisers scrambling to secure deals for their clients.
Mr Kirtikar illustrated the real-world consequences with a recent case from his firm. A client purchasing a home was initially offered a rate of 4.18 per cent in early March, equating to monthly payments of £2,585.
Just two weeks later, before the buyer had finalised their decision, the lender pulled the product due to shifting market conditions. The client ultimately secured a rate of 5.18 per cent instead — pushing their monthly payment to £2,909.73.
That fortnight of hesitation cost the borrower an additional £324.73 every month.
"It highlighted the need to communicate with advisers quickly in this unpredictable market," Mr Kirtikar observed.
Current projections suggest around 5.2 million mortgage holders could see their repayments increase by the end of 2028
| GETTYThe Bank of England's financial stability report paints a broader picture of the challenges ahead. Current projections suggest around 5.2 million mortgage holders could see their repayments increase by the end of 2028.
This figure represents a significant jump from the 3.9 million predicted before the Middle East conflict began.
Average two-year fixed-rate mortgages have climbed by roughly 0.8 percentage points, whilst five-year fixes have risen by approximately 0.7 percentage points.
The Monetary Policy Committee held interest rates at 3.75 per cent last month but signalled potential increases ahead due to inflationary pressures.
Lenders have responded by raising their rates substantially and reducing available products. The total number of mortgage deals on the market has dropped from 8,500 to 7,000.
Good options remain available in the market for those who approach their decisions methodically
| GETTYThe Bank noted, however, that this availability still exceeds levels seen during the Covid-19 pandemic and the 2022 mini-budget turmoil.
While the Bank of England has suggested that typical payment increases should remain modest compared with recent years, Mr Kirtikar noted that individual experiences can vary considerably.
"We are still seeing borrowers coming off much older fixed rates, and in those cases, the rise in monthly payments can absolutely feel like a shock," he said.
Nevertheless, he urged homeowners not to let concern tip into panic. Good options remain available in the market for those who approach their decisions methodically.
"In this market, early advice creates flexibility, whereas panic doesn't help anyone," he concluded.
