The end of the draw period is the most significant moment in the lifecycle of a HELOC. The facility transitions automatically from a revolving credit line to a standard repayment loan, monthly payments typically increase, and the borrower loses the ability to make further draws. For many borrowers, this transition prompts the question: should I continue on the repayment terms, or refinance to something different?

This guide covers what happens when the draw period ends, the situations where refinancing makes financial sense, the four main options available, and the costs involved. Refinancing is not always the right answer. Sometimes continuing on the existing repayment terms is the simplest and cheapest route. But understanding the options before the transition happens puts the borrower in a stronger position to make an informed decision. All figures are illustrative only.

What happens when the draw period ends

The transition from the draw period to the repayment period is automatic. The borrower does not need to reapply, sign new paperwork, or take any action. On the date the draw period ends (as specified in the original agreement), the HELOC facility closes to further draws and the outstanding balance begins repayment over the remaining term. The guide to what is a HELOC covers the full two-phase lifecycle.

Monthly payments increase at this point because the borrower moves from interest-only to capital-plus-interest. The size of the increase depends on two factors: how much was drawn during the draw period and how long the remaining repayment term is. During the draw period, the borrower pays interest only on the accumulated drawn balance. When the repayment period begins, the full outstanding balance is repaid with capital-plus-interest over the remaining term.

As an illustrative example, a borrower who took a twenty-year HELOC with a five-year draw period and has £35,000 outstanding when the draw period ends would repay that £35,000 over the remaining fifteen years. At an illustrative variable rate of 8%, the monthly repayment would be approximately £335 per month. If the full £35,000 was drawn by the end of the draw period, the interest-only payment at that point would be approximately £233 per month. The transition to £335 represents an increase of roughly £102 per month (approximately 44%). On larger balances or shorter remaining terms, the increase can be proportionally greater.

This payment increase is not a surprise in the sense that the lender would have stress-tested for it during the original affordability assessment. But it can feel significant in practice, particularly if the borrower’s circumstances have changed since the HELOC was taken out. This is why reviewing the position as the draw period approaches its end, rather than waiting until after it has passed, is worthwhile.

When refinancing makes sense

Refinancing is not automatically the right answer when the draw period ends. If the existing rate is competitive, the monthly payment during the repayment period is affordable, and the borrower has no need for further revolving access, continuing on the existing terms is the simplest route and avoids the cost of a new application. Refinancing makes sense in specific situations where the benefit outweighs the cost.

The most common reason to refinance is to secure a lower rate. If market rates have fallen since the original HELOC was taken, or if the borrower’s credit profile has improved (allowing access to a more competitive rate tier), a new product at a lower rate can reduce the monthly payment and the total interest cost over the remaining term. The rate saving must be large enough to cover the fees of the new application within a reasonable period.

A second common reason is to restore revolving access. If the borrower still needs the ability to draw and redraw, for example because a phased project is not yet complete or because ongoing staged costs (such as school fees) extend beyond the original draw period, a new HELOC with a fresh draw period provides this. The alternative is to take a separate loan for the remaining costs, which involves a second set of fees.

Switching product type is a third reason. A borrower who originally chose a variable-rate HELOC may now prefer the certainty of a fixed-rate second charge mortgage for the remaining balance, particularly if interest rates have risen or are expected to rise. Conversely, a borrower who wants to absorb the remaining balance into a first-charge mortgage through a remortgage may access a lower rate than either a new HELOC or a second charge mortgage, though this means replacing the existing mortgage deal.

Changed circumstances can also prompt refinancing. If the borrower’s income has increased, their property has risen in value, or adverse credit has been cleared, the terms available on a new product may be materially better than the terms on the original HELOC. The guide to HELOC rates in the UK covers how LTV and credit profile affect the rate offered.

The four main options

When the draw period ends (or at any point during the HELOC term, given the absence of early repayment charges on current UK products), the borrower has four main routes. Each has a different cost, flexibility, and speed profile.

The first three options all involve taking on a new financial product, which means new fees. The fourth option eliminates the debt entirely but requires available funds. For most borrowers, the decision comes down to whether the cost of the new product (fees plus ongoing interest) is justified by the benefit it provides over simply continuing on the existing HELOC repayment terms.

It is worth noting that the existing HELOC repayment terms are not inherently bad. The rate is already agreed, the balance is reducing each month, and the loan will be fully repaid within the remaining term. Refinancing only improves the position if the new product offers a materially better rate, a more suitable structure, or access to features (like revolving drawdown) that the repayment period does not provide.

Costs of refinancing

Refinancing a HELOC is a new application with a new set of fees. Exiting the existing HELOC carries no cost (the products currently available in the UK do not have early repayment charges), but entering the new product does. The typical costs include lender fees (product fee and arrangement fee), broker fees (where applicable), valuation fees, and legal costs. The guide to HELOC fees and costs covers the lender fee categories in detail.

The total cost of refinancing must be weighed against the benefit it provides. The simplest way to assess this is to calculate the break-even period: how many months of savings does it take to recover the upfront cost of refinancing?

This break-even calculation is simplified. In practice, the comparison should also consider whether the new product extends the total repayment period (which increases total interest even if the monthly payment is lower), whether the new rate is fixed or variable (a variable rate could move, changing the saving), and whether the borrower’s plans might change again within the break-even period. The guide to HELOC rates in the UK covers how rate changes affect costs, and the guide to fixed vs variable rate HELOCs covers the rate type decision.

What affects eligibility for refinancing

Refinancing means qualifying for a new product under current criteria, not the criteria that applied when the original HELOC was taken. This is an important distinction because the borrower’s circumstances, the property value, and the market conditions may all have changed.

The property will be revalued. If the property has increased in value since the original HELOC, the combined LTV will be lower, which may qualify the borrower for a more competitive rate tier. If the property has fallen in value, the combined LTV will be higher, which may restrict the available options or push the borrower into a less competitive rate tier. The guide to understanding LTV for HELOCs covers how LTV affects the rate and amount available.

Income and affordability will be reassessed. If the borrower’s income has increased or their other commitments have decreased since the original HELOC, refinancing should be straightforward from an affordability perspective. If income has decreased (for example, due to retirement, redundancy, or a career change), the new affordability assessment may produce a different result. The maximum borrower age (typically 80 at end of term at the time of writing) also applies to the new product, which may constrain the available term length for older borrowers.

The credit profile will be reassessed. If the borrower has maintained clean payments on the existing HELOC and other commitments since the original application, the credit profile may have improved. If new adverse credit has been added to the file, the refinancing options may be more restricted. The guide to HELOC eligibility covers the full eligibility picture.

In some cases, the borrower’s circumstances may have changed enough that refinancing does not produce a better outcome than continuing on the existing repayment terms. This is not a failure; it simply means the existing product is still the best available option. The absence of early repayment charges means the borrower retains the flexibility to refinance at a later date if circumstances improve further.

Frequently asked questions

Do I have to refinance when the draw period ends?

No. The transition from draw period to repayment period is automatic and requires no action from the borrower. The outstanding balance continues to be repaid under the existing terms, with monthly capital-plus-interest payments over the remaining term. The rate (variable or fixed, depending on the product) continues as before.

Refinancing is optional and only makes sense if it produces a material improvement, such as a lower rate, a lower monthly payment, restored revolving access, or a switch to a more suitable product type. If the existing terms are acceptable and affordable, continuing without refinancing is the simplest and cheapest route because it avoids the fees associated with a new application.

Can I refinance mid-term, before the draw period ends?

Yes. The HELOC products currently available in the UK do not carry early repayment charges, so the borrower can repay the existing HELOC in full at any time, whether during the draw period or the repayment period, without incurring an exit penalty. The costs of refinancing are limited to the fees on the new product.

Refinancing before the draw period ends may make sense if market rates have fallen significantly, if the borrower’s circumstances have improved enough to qualify for a materially better rate, or if the borrower wants to switch to a different product type (for example, from a variable HELOC to a fixed-rate second charge mortgage). The break-even calculation described in this guide applies regardless of when in the term the refinancing occurs.

Will I need a new property valuation?

Yes, for a new HELOC or a new second charge mortgage. The new lender will need to assess the current property value to calculate the combined LTV. Most UK HELOC providers use an automated valuation model (AVM) at no cost, though a physical RICS valuation may be required in some cases. If the borrower is remortgaging with the same first-charge lender (for example, as a product transfer with additional borrowing), a new valuation may not always be required, though this depends on the lender’s policy.

If the property has increased in value since the original HELOC, the new valuation will produce a lower combined LTV, which may qualify the borrower for a better rate. If the property has fallen in value, the opposite applies. Home improvements that have added value to the property may help, but the improvement must be reflected in the valuation to affect the LTV calculation.

Can I refinance if my property value has fallen?

The new LTV calculation will use the current property value, not the value at the time the original HELOC was taken. If the property value has fallen, the combined LTV will be higher, which may push the borrower into a less competitive rate tier or, in more extreme cases, may mean the combined LTV exceeds the provider’s maximum (typically 85%). In that situation, refinancing to a new HELOC may not be possible.

Alternatives in this scenario include continuing on the existing repayment terms (which are not affected by the property value change), repaying the HELOC in full if funds are available, or waiting for property values to recover before reassessing the refinancing options. A standard second charge mortgage from a specialist provider may offer higher LTV thresholds than a HELOC, which could provide an alternative route.

Is it better to refinance or just repay?

If the borrower has the funds to repay the HELOC in full, repaying eliminates all future interest and avoids the fees of a new application. This is the cheapest option in total cost terms. The trade-off is that it ties up cash that might be needed or invested elsewhere.

Refinancing makes more sense when the borrower does not have the funds to repay in full, or when the funds are better deployed elsewhere (for example, earning a return that exceeds the HELOC interest rate). The decision depends on the borrower’s wider financial position, not just the HELOC in isolation. Neither option is inherently better; it depends on whether the borrower’s priority is eliminating the debt or maintaining liquidity.

Refinancing involves a new application with new fees, a new valuation, and a new affordability assessment. The costs and benefits of refinancing depend on individual circumstances, including the outstanding balance, current and available rates, fees, and the expected holding period. Actual outcomes will depend on your individual circumstances.
