Remortgaging drives mortgage market growth in Q1 2026

UK Finance data for Q1 2026 shows that remortgaging now accounts for more than half of all buy-to-let mortgage applications — up from 46.6% a year earlier to 55% — as borrowers actively shop around rather than defaulting to their existing lender’s standard variable rate. For contractors with a BTL property or a residential mortgage coming off a fixed term, the data sends a clear signal: remortgaging is what the market is doing right now, and sitting on an SVR is increasingly expensive.

Q1 2026 mortgage market at a glance

Metric	Q1 2026	Year-on-year change
Total new buy-to-let loans	58,272 (£10.8bn)	+3.26% by number, +7.02% by value
BTL remortgages	39,160	+11.1%
BTL remortgages as share of applications	55%	Up from 46.6%
BTL purchase loans	16,871	−14.9%
BTL mortgages in arrears (>2.5% balance)	8,960	−560 quarter-on-quarter

The divergence between purchase and remortgage activity tells a consistent story: buyers remain cautious about committing to a new purchase in an uncertain rate environment, while existing mortgage holders are actively refinancing to reduce their monthly costs. The 11.1% rise in BTL remortgages is the most significant number in the dataset.

Regional picture

Purchase volumes did not fall uniformly. Scotland (+22.6%) and Wales (+20.6%) saw year-on-year rises in Q1 purchase activity, while England (−18.7%) and Northern Ireland (−11.8%) saw declines. The Scotland and Wales figures may partly reflect the relative affordability of those markets and a lower base from recent years. England’s decline reflects the higher average property values and the stronger brake that higher mortgage costs apply to buying decisions.

Why contractors should pay attention

The remortgage surge in the broader market reflects something straightforward: a large number of borrowers who fixed at sub-2% rates in 2020 and 2021 are now rolling off those deals, typically onto rates two to three times higher. The ones who are remortgaging are actively seeking the best available deal. The ones who are not are paying their lender’s SVR, which is typically well above the best available fixed rate.

For contractors, the assumption has often been that remortgaging is harder than it is for employed borrowers — that fewer lenders will accept day-rate income, that the process takes longer, and that the result will be less favourable anyway. That assumption is increasingly outdated. The criteria landscape has shifted meaningfully in the last 12–18 months. Specialist lenders who assess contractor income correctly are competitive on rates, and brokers who work with this borrower type regularly can navigate the application efficiently.

If you have a BTL or residential mortgage that is approaching the end of its fixed term — or that has already rolled onto the SVR — the Q1 data is a prompt to act. Arrears data also improved over the quarter, suggesting that borrowers who have remortgaged to lower rates are managing their commitments more comfortably.

What a remortgage review involves for a contractor

A remortgage review for a day-rate contractor typically covers:

• Your current mortgage terms — remaining fixed period, early repayment charges, current rate
• The lenders whose criteria fit your income structure (limited company salary/dividends, day-rate annualisation, or umbrella payslips)
• The best available rate across that subset, and whether the cost of switching outweighs the saving
• Documentation needed — typically the current contract, 12 months of contracting history, and company accounts or tax computations

The review itself does not commit you to anything. It gives you the information you need to decide whether switching makes financial sense.
