In 2026, one of the most common caveats borrowers raise when discussing a remortgage is also one of the most dangerous: “We’re planning to move soon.”

For many households, that phrase feels reassuring rather than concerning. It suggests flexibility, foresight, and an awareness that today’s mortgage is not a long-term solution. Borrowers often believe they are simply buying time until their next move, whether that is upsizing, downsizing, relocating, or responding to changes in work or family circumstances.

What most do not realise is that lenders interpret “planning to move soon” very differently. In the current market, remortgaging ahead of a move is not neutral. It actively shapes lender risk, product suitability, early repayment exposure, and future affordability assessments in ways that can materially affect outcomes when the move actually happens.

At Willow Private Finance, we increasingly see clients who remortgaged with sensible intentions, only to find themselves constrained, penalised, or forced into suboptimal decisions when their plans evolved. This article explains why remortgaging in 2026 while planning to move requires more strategic thinking than many borrowers expect—and how to avoid common mistakes that only become visible too late.

Why “Planning to Move” Matters to Lenders in 2026

Mortgage lending in 2026 is fundamentally forward-looking. While affordability calculations still rely on current income and commitments, product pricing and risk appetite are shaped by what lenders believe is likely to happen during the life of the loan.

When a borrower signals, implicitly or explicitly, that they are likely to move within a relatively short timeframe, lenders assume a higher probability of early redemption, porting requests, or additional borrowing. This alters how suitable certain products are, even if headline affordability is strong.

The mistake borrowers often make is assuming that because a remortgage is technically possible, it is therefore strategically appropriate. In reality, lenders design many fixed-rate products on the assumption that borrowers will remain in place for the full term. When that assumption is broken, the cost of flexibility becomes visible through early repayment charges, restrictive porting conditions, or inflexible loan structures.

The Illusion of Certainty Around Moving Timelines

Another issue that repeatedly causes problems is overconfidence in moving timelines.

Very few households move exactly when they expect to. Sales fall through. Purchases collapse. Planning decisions take longer than anticipated. Children’s schooling changes. Job opportunities accelerate or disappear. In 2026, conveyancing delays remain common, and even straightforward chains can drift by months.

When borrowers remortgage on the assumption that they will move “in about two years,” they are often surprised to discover how quickly two years passes—and how narrow the margin for error can be once early repayment charges and lender conditions are factored in.

A remortgage that appears safe on paper can become expensive simply because life fails to stick to schedule.

Early Repayment Charges: More Than a Technical Detail

Early repayment charges are frequently discussed, but rarely fully understood.

In 2026, most fixed-rate mortgages still carry ERCs that apply for a defined period, often stepping down gradually over time. These charges are typically calculated as a percentage of the outstanding loan balance, not the original borrowing amount, which means they remain material even several years into a deal.

Borrowers planning to move often underestimate both the size of these charges and the likelihood that they will be triggered. Many assume they will simply port the mortgage, or that ERCs will be negligible by the time they move. In practice, neither assumption is guaranteed.

Where a mortgage is redeemed early because porting is not possible, or because the new borrowing requirement cannot be accommodated, ERCs become a real cash cost that must be paid at completion. For higher-value mortgages, this can run into tens of thousands of pounds.

Portability: A Feature, Not a Promise

Portability is frequently misunderstood as a safety net. While many mortgages are technically portable, portability is always conditional.

In 2026, porting a mortgage requires a full reassessment of affordability based on current lender criteria. Any changes to income, employment structure, credit commitments, or household expenditure can affect the outcome. The new property must also meet the lender’s criteria, which can be an issue with non-standard construction, rural locations, or higher-value homes.

If additional borrowing is required, that portion is assessed separately and often at different rates, which can further complicate the overall cost. If any element fails, the lender is entitled to refuse porting altogether.

Borrowers who remortgage assuming they will “just port it” often discover too late that portability is not within their control.

The Interaction Between Remortgaging and Future Affordability

Another overlooked risk is the assumption that future affordability will be easier than it is today.

When you move, the lender reassesses affordability at that point in time, not based on the assumptions that applied when you remortgaged. If income has changed, expenses have increased, or lender stress rates have shifted, borrowing capacity may be lower than expected.

This is particularly relevant in households where one partner has reduced working hours, income has become more variable, or childcare costs have increased. A remortgage that works perfectly today may not support the onward purchase tomorrow.

In these cases, borrowers can find themselves unable to port their mortgage or borrow the additional funds required, forcing an early redemption and triggering ERCs that were assumed to be avoidable.

Short Fixes, Long Fixes, and the False Choice Between Them

Borrowers planning to move often frame the decision as a choice between a short fixed rate to remain flexible, or a longer fix to secure certainty.

In reality, both options carry risks.

Short fixes can leave borrowers exposed to higher rates, affordability reassessment at the wrong moment, or reversion to standard variable rates if the move is delayed. Longer fixes provide rate certainty but often come with more punitive ERC structures and stricter porting conditions.

In 2026, the correct approach is rarely about fix length alone. It is about aligning the mortgage structure with the uncertainty of the moving plan, rather than pretending certainty exists where it does not.

Case-Type Insight: A Typical Outcome

A common scenario involves a household remortgaging into a competitive five-year fixed rate in early 2026, planning to move within two to three years. Eighteen months later, circumstances change. A job relocation accelerates the move, but income structure has shifted slightly and borrowing needs are higher than originally anticipated.

The lender declines porting due to affordability constraints. The mortgage must be redeemed. Early repayment charges apply at a rate that wipes out any benefit gained from the original remortgage.

What appeared to be a prudent decision becomes a costly constraint, not because the borrower acted recklessly, but because the mortgage was structured without enough tolerance for change.

Structuring a Remortgage That Preserves Optionality

Remortgaging while planning to move is not inherently wrong. The issue is how the mortgage is structured.

In some cases, shorter fixes with modest ERCs make sense. In others, splitting borrowing into separate parts can reduce exposure. Certain lenders offer more pragmatic porting policies or ERC structures that taper earlier.

The goal is not to predict the future perfectly, but to ensure that the mortgage does not punish you for adapting to it.

This is where independent advice becomes critical. A whole-of-market broker can assess not just rates, but how a mortgage will behave when plans evolve.

Outlook for 2026 and Beyond

Borrowers are becoming more mobile, not less. Hybrid working, international moves, and lifestyle-driven decisions mean that fewer households remain static for long periods.

However, mortgage products are still largely designed around stability. The tension between these two realities is where many remortgaging mistakes occur.

In 2026, flexibility is not free. But rigidity is often far more expensive than borrowers expect.
