Mortgage borrowing increased sharply in June, but the underlying figures present a more complicated picture than the headline growth suggests.

Bank of England data shows that individuals borrowed a net £7.7 billion of mortgage debt during the month, up from £3.3 billion in May and above the previous six-month average of £4.9 billion. The annual growth rate of net mortgage lending also increased slightly, from 3.5% to 3.6%.

At first sight, this might suggest that confidence and activity are returning decisively to the housing market. However, the volume of borrowing increased at the same time as the cost of newly drawn mortgages rose.

The effective interest rate actually paid on new mortgages increased from 4.22% in May to 4.35% in June. The average effective rate across the outstanding stock of mortgages also continued to rise, reaching 3.96%, compared with 3.92% a month earlier.

House-purchase approvals improved from 56,600 to 58,200, but remained below their previous six-month average of approximately 61,400.

Approvals for remortgaging with a different lender increased only modestly, from 33,800 to 34,200.

The figures therefore do not describe a market in which mortgage availability has suddenly become easier or borrowing materially cheaper. They show more debt being drawn while new borrowing costs rise and future purchase activity remains relatively subdued.

For borrowers with large mortgages, changing income or fixed rates ending over the next year, this is an argument for early financial planning rather than waiting for an assumed improvement in mortgage pricing.

A Large Increase in Net Borrowing Does Not Mean Purchases Doubled

Net mortgage borrowing measures the amount of new mortgage debt advanced after repayments have been taken into account. It should not be confused with the total value of new mortgages or with the number of homes purchased.

Gross secured lending increased only slightly in June, from £27.2 billion to £27.4 billion. At the same time, repayments fell from £22.7 billion to £21.3 billion. The combination produced a much larger net borrowing figure.

This distinction matters because a higher net flow can arise for several reasons. More borrowers may be completing purchases, but the average mortgage could also be larger. Existing homeowners may be raising additional capital, while fewer borrowers may be redeeming or reducing their loans.

Transactions delayed during previous months may also have completed in June, concentrating lending that had already been approved. The Bank’s purchase-approval figures indicate that the forward pipeline remained weaker than the headline borrowing total might imply.

The increase from 56,600 to 58,200 purchase approvals was positive, but approvals remained approximately 3,200 below their preceding six-month average. That suggests the market is continuing to transact, rather than accelerating into an unambiguous mortgage-led recovery.

For borrowers, the more commercially important question is not whether the aggregate market borrowed £7.7 billion. It is what rate, structure and monthly commitment now apply to the individual loan.

Newly Drawn Mortgage Rates Are Moving in the Wrong Direction

The increase in the effective rate on newly drawn mortgages from 4.22% to 4.35% represents a 13-basis-point monthly rise.

That change may appear modest, but the financial effect becomes more material as the loan size increases. A borrower refinancing a small balance may absorb a limited increase without substantially changing household expenditure. A client refinancing £500,000, £1 million or more can experience a much larger cash-flow effect from relatively small movements in pricing.

The effective rate is an average across mortgages actually drawn during the month. It does not mean that every new borrower paid 4.35%, nor does it represent one particular two-year or five-year fixed product.

Individual pricing will depend on loan-to-value, loan size, property type, repayment method, income profile, credit history and the selected lender. Product fees can also make two apparently similar rates produce different overall costs.

Nevertheless, the direction is important. Clients waiting for mortgage costs to fall automatically may find that their current assumptions no longer match the market available when they need to refinance.

The Bank of England’s July Financial Stability Report also noted that quoted mortgage rates had risen following movements in market rates. It reported average rates of 4.92% for a two-year fixed mortgage at 75% loan-to-value and 5.32% at 90% loan-to-value at the time of its analysis.

The same report projected that slightly more than five million mortgaged households could experience an increase in repayments by the end of 2028. Approximately 750,000 households paying less than 3% were expected to come off fixed rates during 2026, with an average projected increase of £170 a month.

Those are aggregate projections rather than forecasts for individual borrowers, but they reinforce the practical issue: the refinancing challenge is not over simply because the largest interest-rate shocks may have already passed.

The Outstanding Mortgage Stock Is Still Repricing Upwards

The average rate on the outstanding stock of mortgages rose to 3.96% in June. This reflects the gradual replacement of older, lower-rate mortgages with newer borrowing priced in a more expensive environment.

Many fixed-rate borrowers remain temporarily protected from current market rates. Their household budgets still reflect a product arranged two, three or five years earlier.

As those products expire, borrowers refinance, transfer to a new product with their existing lender or move onto a reversionary rate. The new rate then feeds into the average cost of the total mortgage stock.

This process occurs gradually because fixed rates end at different times. The average stock rate can therefore continue increasing even if new product pricing later stabilises.

For borrowers still paying below 2% or 3%, the existing monthly payment can create a false sense of security. The current mortgage may be affordable, but that does not establish that the replacement structure will be equally comfortable.

A review should consider the expected balance at expiry, available rates, remaining term, repayment basis and any changes in income or expenditure since the original loan was arranged.

The objective is not simply to secure another fixed rate. It is to establish whether the present mortgage structure remains suitable in a higher-cost environment.

Borrowing More Can Mask Weaker Affordability

The rise in net lending may partly reflect households requiring more mortgage capital to complete broadly similar transactions.

Where property prices remain high relative to income and buyers have limited ability to increase their deposits, the mortgage must carry more of the purchase cost. A transaction can therefore proceed while the borrower accepts a higher balance and a more expensive interest rate.

This is not necessarily irresponsible. Many households have stable incomes and can afford the proposed commitment. However, the margin for unexpected expenditure can become narrower.

A larger mortgage creates greater sensitivity to future rate changes. It can also make overpayments, moving home or reducing the term more difficult.

Borrowers may focus heavily on passing the lender’s affordability test. That is only one part of the decision. A lender determines whether the mortgage meets its model and responsible-lending requirements; the client must decide whether the payment is compatible with wider financial priorities.

Pension contributions, school fees, investment plans, business commitments and future family expenditure may not be fully represented by a standard affordability calculation.

This is particularly important for high earners whose spending and remuneration can vary materially from year to year. A mortgage can meet the lender’s policy while still placing too much pressure on the borrower’s preferred cash reserves.

Early Refinancing Matters Most for Large Loans

The consequences of delay become more significant as the mortgage balance increases.

A borrower with a loan above £500,000 may find that a relatively small difference in rate produces a meaningful annual cost. For million-pound borrowing, minor changes in pricing, fees or repayment method can become financially substantial.

Large-loan applications may also require more underwriting time. The lender could need detailed evidence of bonuses, company profits, partnership drawings, investments or overseas income. A higher loan-to-income ratio may require referral to a specialist underwriting team or credit committee.

The property may need a more detailed valuation, particularly where it is unusual, high value or located in a market with limited comparable evidence.

Clients should therefore avoid treating the mortgage expiry date as the date on which the refinancing process begins. By that point, the borrower may have limited time to correct documentation, restructure income or reconsider the loan.

An initial review six to twelve months before expiry can identify likely obstacles while the client still has options. The formal application and product reservation can then be timed around lender validity periods, early repayment charges and prevailing pricing.

Complex-Income Borrowers Need More Preparation, Not Less

Self-employed borrowers, contractors, company directors and partners can be disproportionately affected when mortgage costs rise.

The issue is not necessarily that their income has fallen. The difficulty may be that the lender’s assessment captures only part of their financial position.

A company director may receive a modest salary and dividends while retaining significant profit in the business. A contractor may have strong annual earnings but a recently renewed contract or brief gaps between assignments. A partner may receive drawings, profit distributions and deferred remuneration rather than a fixed monthly salary.

When refinancing was inexpensive and the required loan modest relative to income, these distinctions may have had limited effect. A higher rate can reduce affordability and make the lender’s treatment of each income component more important.

A borrower who qualified comfortably for the existing loan may not achieve the same result under a different lender’s current affordability model.

Early planning allows the adviser to establish which lenders can use retained profits, recent accounts, day-rate income, bonuses, commission or other relevant earnings. It also gives the client time to obtain accounts, tax calculations, contracts and current management information.

Waiting until the fixed rate is close to expiry can turn an evidence problem into a pricing problem. The client may have to accept the existing lender’s product-transfer options because there is insufficient time to complete a more suitable external remortgage.

A Product Transfer May Be Convenient but Not Optimal

Remaining with the existing lender can offer important advantages. A product transfer may not require a full affordability assessment, new legal work or a physical valuation. It can be quicker and less intrusive than moving to another bank.

For some clients, it will be the strongest option.

However, convenience should not prevent comparison. The existing lender may not offer the most competitive rate, longest term or most suitable interest-only structure. It may also be unwilling to provide additional capital or recognise changes in the client’s financial position.

A borrower seeking no change other than a replacement fixed rate can compare the product-transfer options with the wider market. Where capital raising, a term extension or another structural change is required, the review becomes more detailed.

The borrower should also consider any early repayment charge, product fee and incentive package. A lower headline rate with a substantial fee may not be cheaper over the selected period.

The role of the review is not to move the mortgage unnecessarily. It is to establish whether staying is a positive decision rather than the outcome of running out of time.

Interest-Only Borrowers Need to Review Both Cost and Exit

Interest-only borrowing can reduce the monthly payment because the client is not contractually repaying the capital balance each month. It can be appropriate for borrowers with credible repayment strategies, substantial investments or irregular income.

However, higher rates pass directly into the monthly interest cost.

A capital-repayment borrower also experiences the effect of a higher rate, but part of the monthly payment continues to reduce the balance. An interest-only borrower may pay considerably more each month without reducing the debt at all.

The repayment strategy must therefore be reviewed alongside the new rate.

A client planning to repay the mortgage through investments should establish whether the portfolio remains sufficient and whether using it would disrupt other objectives. A borrower relying on the sale of the property should consider the expected timing, future housing needs and whether the mortgage term remains appropriate.

Where the loan is large, a partial repayment may improve both affordability and lender choice. Alternatively, dividing the borrowing between interest-only and capital repayment can create a more balanced structure.

Extending interest-only borrowing without reviewing the eventual exit merely postpones the central issue.

Capital Raising Should Be Assessed Against the Purpose of the Funds

Higher mortgage borrowing can also reflect homeowners releasing equity rather than simply purchasing or refinancing an unchanged balance.

Capital may be raised for home improvements, investment, business purposes, tax liabilities, divorce settlements, family assistance or debt consolidation.

Using mortgage borrowing can reduce the immediate interest cost compared with credit cards and unsecured personal loans. However, the debt may then remain outstanding for a much longer period and become secured against the home.

The borrower should compare the total cost over the expected term rather than the monthly payment alone.

Debt consolidation requires particular care. Reducing a group of expensive monthly commitments can improve cash flow, but it does not address the behaviour or financial event that created the balances. If unsecured borrowing is rebuilt after consolidation, the household can become more indebted than before.

Capital raising for investment or business purposes introduces different risks. The return is uncertain, while the mortgage commitment remains contractual.

The financing structure should match the purpose and expected duration of the funds. Long-term mortgage debt may be unsuitable for a temporary requirement where a shorter facility or planned asset sale provides a clearer exit.

Borrowers With Investments Have More Than One Option

Clients holding substantial investments or other assets do not always need to refinance the full mortgage through a conventional product.

Some may choose to reduce the balance using cash or investments, particularly where the risk-adjusted investment return no longer justifies maintaining larger mortgage debt. Others may prefer to preserve the portfolio for long-term growth, liquidity or tax planning.

High-net-worth borrowers may have access to private-bank lending, Lombard facilities or offset structures, depending on their assets and wider relationship.

These alternatives need to be assessed on a total-cost basis. A private bank may offer flexible lending but require a significant investment transfer. Lombard borrowing can provide liquidity against a portfolio but introduces the risk of margin calls if asset values fall.

Using investments to repay the mortgage can also have tax, market-timing and portfolio consequences.

The correct strategy depends on whether the client values low monthly expenditure, investment continuity, access to liquidity or maximum borrowing flexibility.

The key is to make that decision before the existing mortgage reaches expiry, rather than selling assets or accepting a new facility under time pressure.

Changing Income Can Alter the Best Lending Route

A borrower’s circumstances may look very different from when the present mortgage was arranged.

An employee may now be self-employed. A business owner may have sold a company and moved from earned income to investment income. A client may have retired, reduced working hours or started receiving pension benefits.

Divorce, parental leave or a move abroad can also change the relevant lender market.

These changes do not necessarily make refinancing impossible. They may require a different underwriting approach.

A private bank may be suitable for a client with substantial assets but limited conventional income. A specialist lender may be more effective for recent self-employment, retained profits or unusual remuneration. An existing lender’s product transfer may provide continuity where a new affordability assessment would be restrictive.

The strongest route cannot be identified from the mortgage balance and property value alone. The client’s current income, assets, residency and future plans must be reviewed together.

Divorce and Separation Can Create Urgent Refinancing Needs

Divorce lawyers and private-client solicitors frequently encounter mortgage issues before the parties have established whether the proposed settlement is financeable.

One person may intend to retain the home and release the other from the mortgage. That can require a transfer of equity, a new affordability assessment and sometimes additional borrowing to fund the settlement.

Higher mortgage rates make these arrangements more difficult because the remaining borrower must support the debt alone at current pricing.

A settlement that appears equitable on paper may not work if the intended borrower cannot obtain the required mortgage. The alternatives could involve reducing the lump sum, using other assets, arranging family support or selling the property.

Mortgage advice should therefore be obtained before the financial settlement is finalised wherever housing debt is central to the outcome.

Early assessment does not determine the legal agreement, but it can prevent the parties from relying on a refinancing structure that no lender will provide.

Remortgage Approvals Capture Only Part of the Market

The Bank of England reported 34,200 remortgage approvals in June, up from 33,800 in May. These figures include remortgages involving a move to a different lender.

They do not capture every borrower taking a new rate.

A substantial number of clients complete product transfers with their existing lender. Those arrangements can be commercially significant but do not appear as external remortgage approvals in the same way.

The relatively modest increase in approvals should therefore not be interpreted as meaning that few borrowers are refinancing. It does, however, indicate that external lender switching remains restrained compared with stronger periods.

This may reflect borrowers choosing the convenience of product transfers, limited savings from moving, affordability constraints or insufficient time to complete a new application.

For advisers, it highlights an important opportunity. Clients should compare the available routes before they become committed to the easiest one.

Waiting for Rates to Fall Is Not a Complete Strategy

Some borrowers may be reluctant to arrange a new fixed rate because they expect mortgage pricing to improve.

That expectation could prove correct. Rates can move in either direction as inflation, Bank Rate expectations and wholesale funding markets change.

The problem is that the borrower still needs a plan if pricing does not improve by the required date.

Allowing the existing fixed rate to expire without arranging a replacement can result in the mortgage moving onto a lender’s standard variable or reversionary rate. That rate may be materially higher than the fixed products available.

A more disciplined approach is to review the market early, identify suitable options and understand whether a product can be reserved in advance. The client can then monitor pricing and reconsider the choice if a genuinely better alternative becomes available before completion, subject to lender rules and any costs already incurred.

This preserves flexibility without making the entire refinancing strategy dependent on an uncertain rate forecast.

Overpaying Before Refinance Can Improve the Structure

Borrowers with surplus cash may benefit from reducing the mortgage balance before the next product begins.

An overpayment can lower the monthly interest cost and may move the mortgage into a more favourable loan-to-value band. The latter can improve access to products or pricing where the balance is close to a lender threshold.

The decision should take account of early repayment allowances and charges under the existing mortgage.

Liquidity must also be preserved. Using all available cash to reduce the loan can leave the household exposed to unexpected costs or force it to borrow again later.

For company directors and entrepreneurs, personal liquidity may be particularly valuable where income is irregular or connected to business performance.

The decision is therefore not simply whether cash earns less than the mortgage rate. It is how much liquidity the client needs and whether reducing the balance materially improves the refinancing options.

Extending the Term Can Reduce Payments but Increase Total Cost

Where affordability is under pressure, extending the mortgage term can lower the required monthly payment.

This can be useful for clients whose income remains strong but whose new rate would otherwise produce an uncomfortable commitment. It may also help borrowers absorb a temporary period of higher expenditure.

The trade-off is that interest is charged for longer, increasing the likely total cost unless the borrower later overpays or reduces the term.

Age limits can restrict the available term. Lenders may require evidence of retirement income where the mortgage extends beyond the borrower’s expected working life.

A term extension should therefore be treated as a structural choice rather than an automatic solution. The client should understand the projected balance and interest cost, together with any plan to shorten the term later.

Early Review Creates More Options

The June figures present a mortgage market that is active but not straightforward. Net borrowing rose strongly, yet purchase approvals remained below their recent average and the cost of new mortgages increased.

That combination is commercially important.

Borrowers are continuing to buy, refinance and raise capital, but they are doing so in an environment where the money itself is becoming more expensive. For clients with large loans or unconventional income, the difference between a well-planned refinancing and a last-minute replacement product can be substantial.

The strongest review begins before the lender sends its final maturity reminders. It examines the existing balance, rate, early repayment charge, property value, income, assets, repayment method and future capital needs.

It should also consider what has changed. A client may now have retained business profits, investment assets, a lower loan-to-value or a different property portfolio. Another may have more expenditure, reduced income or a repayment strategy that needs revisiting.

These factors determine whether the appropriate solution is an external remortgage, product transfer, private-bank facility, specialist mortgage, partial repayment or a broader restructuring of the debt.



Mortgage borrowing may have surged in June, but the figures do not show that borrowing has become cheaper or easier. They show why clients approaching a refinancing event should start planning while they still have the widest range of choices.
