You took out a personal loan at the rate you were offered at the time. Since then, your credit score may have improved, market rates may have moved, or you may simply have seen lower rates advertised elsewhere and wondered whether you are paying more than you need to. Refinancing, which means taking out a new loan to repay the existing one, can reduce the total cost of borrowing. But it does not always save money, and the calculation is not as simple as comparing two APR figures.
This guide explains how refinancing works, what the Consumer Credit Act says about early repayment charges, how to calculate whether switching would genuinely save money after all costs, and when you are better off staying where you are. All figures used are illustrative. This article is for informational purposes and does not constitute financial advice.
At a Glance
-
Early repayment charges on personal loans are capped by law. The maximum is 1% of the amount repaid early, or 0.5% if 12 months or fewer remain.
Under the Consumer Credit Act, a lender can charge up to 1% of the amount being repaid early if there are more than 12 months remaining on the loan, or up to 0.5% if 12 months or fewer remain. Many lenders charge less than the cap, and some charge nothing. These are statutory limits, not guidelines. The charge cannot exceed the total remaining interest on the loan, so on a loan close to the end of its term the actual charge may be lower than the percentage cap suggests.

The question is not whether the new rate is lower. It is whether the interest saving exceeds the settlement fee plus any costs on the new loan.
A lower APR on the new loan does not guarantee a net saving. The early repayment charge on the existing loan, any arrangement fee on the new loan, and the hard credit search all have costs. The break-even calculation subtracts these costs from the interest saving. If the result is positive, refinancing saves money. If it is negative or marginal, staying with the existing loan is the simpler and safer option.

Refinancing makes the most sense when the rate gap is significant and the remaining term is long. It rarely makes sense in the final year.
The interest saving from a lower rate compounds over time. A borrower with three years remaining on a loan at a high rate stands to save significantly more than a borrower with eight months remaining. In the final year, the remaining interest is usually too small for the saving to offset the settlement fee and the disruption of a new application. The closer you are to the end of the term, the less likely refinancing is to deliver a net benefit.
How refinancing a personal loan works
Refinancing a personal loan is mechanically straightforward. The borrower applies for a new loan from a different lender (or, in some cases, the same lender) at a lower rate. If approved, the funds from the new loan are used to repay the outstanding balance on the existing loan in full. The original loan is settled, and the borrower makes monthly payments on the new loan for the remainder of the new term.
The process involves three steps. First, the borrower requests an early settlement figure from the existing lender. This figure shows the exact amount needed to repay the loan today, including any accrued interest and the early repayment charge (if applicable). The settlement figure is valid for 28 days from the date it is issued. Second, the borrower applies for a new loan for at least the settlement amount at the lower rate. Third, once the new loan is approved and the funds are received, the borrower uses them to settle the existing loan and confirms the closure in writing.
There is no regulatory barrier to refinancing a personal loan. The right to repay early is provided by the Consumer Credit Act, and the lender cannot refuse an early settlement request. The only cost is the early repayment charge, which is capped by law and, for many lenders, is lower than the statutory maximum or waived entirely.
Early repayment charges: what the law says
The Consumer Credit Act sets out the maximum amount a lender can charge for early repayment of a personal loan. These caps are statutory limits, not discretionary guidelines, and they apply to all regulated consumer credit agreements.
If there are more than 12 months remaining on the loan at the point of early settlement, the lender can charge up to 1% of the amount being repaid early. If there are 12 months or fewer remaining, the cap is 0.5%. In both cases, the charge cannot exceed the total amount of interest that would have been payable over the remaining term. This third condition is important near the end of a loan: if the remaining interest is less than 1% or 0.5% of the balance, the charge is limited to the remaining interest amount, not the percentage figure.
Many lenders charge less than the statutory maximum. Some charge no early repayment fee at all. The terms of the specific loan agreement will state whether a charge applies and at what level. Before deciding to refinance, it is worth checking the agreement or contacting the lender to confirm the exact charge. The guide to how to repay a personal loan early covers the early settlement process and your statutory rights in full.
The break-even calculation
The decision to refinance should be based on a single calculation: does the interest saved by switching to a lower rate exceed the costs of making the switch? The costs include the early repayment charge on the existing loan and any arrangement or administration fee on the new loan. If the net saving is positive and meaningful, refinancing makes sense. If it is negative, marginal, or uncertain, staying with the existing loan is the simpler option.
The following worked example illustrates the calculation. All figures are illustrative.
| Item | Amount |
|---|---|
| Existing loan: outstanding balance | £8,000 |
| Existing loan: current APR | 12% |
| Existing loan: remaining term | 30 months |
| Existing loan: total remaining interest (if kept to term) | Approximately £1,313 |
| Early repayment charge (1% of balance) | £80 |
| New loan: APR offered | 6.9% |
| New loan: term | 30 months |
| New loan: total interest over 30 months | Approximately £733 |
| Interest saving (£1,313 minus £733) | £580 |
| Net saving after early repayment charge (£580 minus £80) | £500 |
In this example, refinancing saves approximately £500 over the remaining 30 months after the early repayment charge is deducted. The monthly payment on the new loan would also be lower (approximately £289 compared to £310 on the existing loan), providing a modest monthly cash-flow improvement as well as a total cost saving.
The loan switching calculator models this calculation for any combination of existing and new loan terms, showing the net saving or net cost before a decision is made.
When refinancing makes sense
Refinancing is most likely to deliver a meaningful saving when three conditions are met: the rate difference is significant, the remaining term is long enough for the saving to accumulate, and the borrower’s credit profile supports a competitive rate on the new loan.
A rate difference of two percentage points or more on a loan with 18 months or more remaining will typically produce a saving that exceeds the early repayment charge. A rate difference of five or more percentage points, which can happen if the borrower’s credit score has improved substantially since the original application, can produce savings of several hundred pounds even on a relatively modest loan. The longer the remaining term, the more months there are for the lower rate to compound its advantage.
The most common trigger for refinancing is a material improvement in the borrower’s credit profile since the original loan was taken out. A borrower who took a loan at a higher-than-average rate because of missed payments on the credit file 18 months ago may now, with those markers fading and a year of on-time loan payments on record, qualify for a significantly better rate. Using a soft-search eligibility checker to test the likely rate on a new loan, without triggering a hard search, is the first practical step. The guide to how to find a low-rate personal loan covers how to identify the best available rate.
When refinancing does not make sense
Refinancing is unlikely to save money in several common situations, and recognising them in advance avoids the unnecessary hard credit search and administrative effort.
If the remaining term is 12 months or less, the total remaining interest on the existing loan is usually small enough that the saving from a lower rate does not justify the settlement charge and the effort of a new application. The closer the loan is to its natural end date, the less interest remains to be saved. A loan with six months remaining has already incurred the majority of its interest cost in the earlier, higher-balance months. Switching at that point captures very little of the benefit.
If the rate difference is small, the saving may be marginal even over a longer remaining term. A one-percentage-point rate reduction on a £5,000 balance with 18 months remaining saves approximately £40 in interest. After the early repayment charge (up to £50 at the 1% cap), the net result is a small loss rather than a saving. The break-even point varies by amount and term, but as a general guide, rate differences below two percentage points on balances below £5,000 rarely produce meaningful savings.
If the borrower’s credit profile has not improved, or has worsened, since the original application, the rate available on a new loan may not be materially better than the existing rate. Running a soft-search eligibility check before applying is the way to test this without risk. If the indicated rate on the new loan is not significantly better, staying with the existing loan avoids the hard search and preserves the credit file.
Finally, extending the term on the new loan to reduce the monthly payment can offset or eliminate the interest saving. Refinancing from a 12% loan with 30 months remaining to a 7% loan over 48 months reduces the monthly payment, but the extra 18 months of interest on the new loan may cost more than the rate saving. Refinancing should be compared on a like-for-like term basis wherever possible.
How refinancing affects your credit file
Refinancing a personal loan creates three events on the credit file, and understanding each is useful for deciding whether the timing is right.
The first is a hard credit search from the new loan application. This is recorded on the credit file and visible to other lenders for 12 months. A single search for a personal loan has a relatively small impact, but if the borrower is planning a mortgage application or other significant credit event in the near future, the timing of an additional hard search is worth considering.
The second is the settlement of the existing loan. The old account is marked as “settled” on the credit file, and the full payment history up to that point is preserved. A settled account with a clean payment record is a positive feature. The account record remains on the file for six years after settlement. The early settlement itself is not flagged as a negative event.
The third is the opening of the new loan account. A new account appears on the credit file with a new balance, a new term, and a fresh payment history starting from zero. The total outstanding debt on the file remains broadly similar (the old loan balance is replaced by the new loan balance), but the account is new, which temporarily reduces the average age of accounts in the borrower’s credit profile. This effect is minor and typically resolves within a few months of on-time payments on the new loan.
For a full explanation of how personal loans interact with credit files at each stage, the guide to how personal loans affect your credit score covers the mechanics in detail.

Can I refinance a personal loan with the same lender?
Some lenders offer the option to refinance an existing loan by replacing it with a new loan at a different rate or term. This is sometimes called a “top-up” or “renewal” and may be offered proactively by the lender if the borrower’s profile has improved or if the lender wants to retain the customer. The process is typically simpler than applying to a new lender because the existing lender already holds the borrower’s data.
However, refinancing with the same lender does not guarantee a competitive rate. The lender may not offer the best rate available in the market, and the borrower should still compare the offered terms against what is available elsewhere using soft-search eligibility tools. The value of the existing relationship is convenience, not necessarily cost. If a different lender offers a significantly lower rate, switching to the new lender is likely to produce a better outcome even with the additional administrative effort.
Will refinancing affect my credit score?
Refinancing creates a hard search on the credit file (from the new loan application), settles the existing account (which shows as a closed, settled account with its full payment history), and opens a new account. The net effect on the credit score is usually small and temporary. The hard search has a minor negative impact that fades over 12 months. The settled account with a clean history is a positive feature. The new account temporarily reduces the average age of accounts but builds positive history as on-time payments accumulate.
If the borrower is planning a mortgage application or other significant credit event in the near future, the timing of the additional hard search and the new account opening is worth considering. For most borrowers, the credit file impact of refinancing is minor relative to the potential interest saving. The guide to how personal loans affect your credit score explains how each type of event appears on the file.
How do I know if I would get a better rate now?
The most effective way to check is to use soft-search eligibility tools offered by comparison services and lenders. A soft search queries your credit file without leaving a visible mark that other lenders can see and without affecting your credit score. It provides an indication of the rate you are likely to be offered by each lender, allowing you to compare against your current rate before committing to a formal application.
If the indicated rate is meaningfully lower than your current rate (as a rough guide, two or more percentage points lower with 18 months or more remaining), it is worth running the break-even calculation to check whether the saving exceeds the costs. If the indicated rate is only marginally better or the same, refinancing is unlikely to deliver a net benefit. The guide to soft searches and eligibility checkers explains how to use these tools effectively.
Can I extend the term when refinancing to reduce my monthly payment?
Yes, but doing so can eliminate the interest saving that motivated the refinancing in the first place. A lower rate on a longer term may produce a lower monthly payment, but the additional months of interest can increase the total cost of the loan even at the reduced rate. Refinancing should be evaluated on total cost, not monthly payment. Extending the term to bring the monthly figure down is only cost-effective if the total interest on the new loan (over the longer term) is still lower than the remaining interest on the existing loan.
As a general principle, comparing on a like-for-like term (matching the new loan term to the remaining months on the existing loan) gives the clearest picture of whether the rate saving is genuine. The loan switching calculator models both scenarios: same-term and extended-term, so the trade-off is visible before any decision is made.
Is there a minimum amount of time I need to wait before refinancing?
There is no regulatory minimum waiting period. A borrower can repay a personal loan early and refinance at any point during the term. The right to early repayment is provided by the Consumer Credit Act and cannot be waived or restricted by the lender. The early repayment charge caps apply from the first day of the agreement.
In practice, refinancing very early in the term (within the first few months) is unusual because the credit profile is unlikely to have changed materially in that time. The scenarios where refinancing makes sense typically involve a loan that has been in place for at least six to twelve months, during which the borrower’s credit position has improved. The guide to personal loans and your consumer rights covers the full set of statutory rights that apply to personal loan agreements.
Squaring Up
Refinancing a personal loan can save a meaningful amount of money when the rate difference is significant, the remaining term is long enough for the saving to accumulate, and the early repayment charge does not eliminate the benefit. The Consumer Credit Act caps these charges at 1% (or 0.5% in the final year), and many lenders charge less. The break-even calculation, which subtracts the settlement fee from the interest saving, is the only reliable way to decide whether switching is worth it. If the numbers work, it is a straightforward process. If they do not, the simplest and cheapest option is to keep paying the existing loan to its natural end.
