UK second charge mortgage lending reached £228 million in March 2026, the highest monthly total recorded since February 2008, according to figures released by the Finance & Leasing Association. The value of new business rose 36% year-on-year, while new agreements climbed 20% to 4,129.
The first quarter of 2026 produced £625 million of second charge lending across 11,489 new agreements, representing 33% growth by value and 22% by volume compared with the same period last year. It is the latest signal in a market expansion that began in early 2024 and accelerated through 2025, a year in which annual second charge lending reached its highest level since the eve of the global financial crisis.
Fiona Hoyle, Director of Consumer Finance & Mortgages and Inclusion at the Finance & Leasing Association, said the data reflected demand for “flexible borrowing options to support household budgeting” at a time when many customers were considering their borrowing options carefully. She added that the figures highlighted the strength of a product that allows borrowers to retain their existing mortgage arrangements while still raising additional finance.
A market shaped by sub-2% legacy mortgages
The resurgence reflects a structural quirk of the UK mortgage market. Millions of homeowners locked into fixed rates below 2% during 2020 and 2021 are now reluctant to remortgage when their deals still have years to run. With the Bank of England base rate held at 3.75% following the Monetary Policy Committee’s 30 April vote, and average two-year fixed mortgage rates having drifted back towards 6% in recent weeks, refinancing the entire mortgage to raise capital often means trading a cheap legacy deal for a materially more expensive one.
A second charge mortgage allows borrowers to raise additional funds against the equity in their home without disturbing the underlying first mortgage. The original deal stays in place at its original rate. The new lending sits behind it as a secondary loan, secured against the same property with the first lender’s consent.
For homeowners whose primary deal is still in its fixed period, the calculation has become straightforward. Refinancing the whole balance at today’s pricing can add hundreds of pounds to monthly payments and trigger early repayment charges that often run into the thousands. A second charge taken alongside the existing mortgage preserves the cheap rate on the larger balance and raises capital only where it is needed.
Loan purpose shifting beyond debt consolidation
For much of the past two years, second charge growth was largely a debt consolidation story. That mix has begun to shift. FLA monthly data shows that while the consolidation of existing loans still accounts for the majority of new agreements, growing numbers are being directed towards home improvements, energy efficiency upgrades and property investment activity. In recent FLA releases, around 22% of new agreements have been for home improvements combined with consolidation, with a further 11% to 12% solely for home improvement work.
The buy-to-let segment is also contributing. Landlords with portfolio equity are using second charges to fund deposits on additional purchases or refurbishment work without restructuring portfolio-wide finance arrangements that are often locked at favourable historic pricing.
Gary Hemming at ABC Finance told us “the homeowners we speak to almost universally don’t want to give up the mortgage deal they’re on. When you’ve got a sub-2% rate with three or four years to run, remortgaging to release £40,000 of equity means paying tens of thousands more in interest over the term. A second charge solves that problem without touching the primary deal, and once the numbers are run the maths is usually clear cut.”
Speed and regulatory scrutiny
Brokers and lenders also point to faster turnaround times as a factor behind the sector’s competitive position. While bridging finance has historically been the fastest route to capital secured against property, second charge processing has compressed significantly. Some lenders now complete cases in days rather than weeks, with at least one £190,000 second charge case reported in early May 2026 as having moved from submission to drawdown in under six hours.
The market has also drawn closer regulatory scrutiny. The Financial Conduct Authority published a review of the second charge sector in early 2026, identifying concerns around debt consolidation advice, the suitability assessments brokers were carrying out, and outcomes for customers with low financial resilience. The FLA said it would continue to work with the regulator on the findings while supporting customers who want to consolidate higher-rate unsecured borrowing into more affordable secured lending.
Outlook
With millions of UK fixed-rate mortgage deals due to expire over the coming year and inflation still running at 3.3%, above the Bank of England’s 2% target, pressure on household budgets is unlikely to ease quickly. Many of those whose deals end this year will face a step up in monthly costs even if the Bank of England resumes cutting the base rate later in 2026.
Activity in the second charge market is now at its strongest level since the eve of the global financial crisis. If first-charge rates stay close to current levels through the rest of the year, and base rate cuts arrive more slowly or in smaller increments than households had been hoping for, the structural drivers that pushed March 2026 to an 18-year high look set to persist well into the second half of the year.
