How Much Could You Save by Consolidating Your Debt? UK Averages Explained
27th March 2026
How much can you save by consolidating your debt in the UK?
UK borrowers consolidating around £8,000 of high interest debt typically save between £500 and £1,200 over three to five years but results vary significantly depending on individual circumstances. Whether you save money, and how much, depends entirely on your current interest rates, the rate you are offered, and the loan term you choose. Oakbrook Finance customers save an average of £110 per month after consolidating through OakbrookOne.
Why managing multiple debts makes progress feel impossible
If you are handling several credit repayments each month two credit cards, a store card, an overdraft you may have noticed that the balances barely seem to move. This is not your imagination.
When minimum payments are largely absorbed by interest, only a small fraction of each payment actually reduces your balance. UK credit cards carry an average APR of around 21%, according to the Bank of England. Store cards frequently sit higher. Unarranged overdrafts can reach 40% APR. Across three or four accounts simultaneously, a meaningful portion of every payment goes back to the lender rather than clearing what you owe.
Debt consolidation addresses this by replacing multiple high interest balances with a single loan at a lower rate. This guide explains what realistic savings look like, what drives them, and equally importantly when consolidation does not make financial sense.
What debt consolidation actually means?
Debt consolidation means taking out one new loan to pay off multiple existing debts credit cards, store cards, catalogues, overdrafts, personal loans leaving you with a single monthly repayment to one provider. It is sometimes called debt refinancing when the primary goal is securing a lower interest rate.
It is worth being clear about what consolidation does not do: it does not reduce the total amount you owe. You are still repaying the same debt what changes is the structure, the rate, and the number of payments you manage. The potential saving comes entirely from that shift in structure.
Why the interest rate gap determines your saving
The gap between your current average APR and the APR you are offered on a consolidation loan is the single most important factor in whether you save money and how much.
For context, the effective interest rate on interest charging credit cards stood at 21.54% in March 2025, while the effective rate on interest charging overdrafts was 22.28% Bank of England, according to the Bank of England's Money and Credit data. The average purchase APR on credit cards has been rising steadily, reaching 35.3% by mid2024 the highest level since Moneyfacts began recording this data in June 2006. Moneyfactscompare Personal consolidation loans range from 6.9% to 34.9% depending on credit profile. Even a few percentage points of difference can represent hundreds of pounds in interest over the life of a loan, particularly when balances are spread across several accounts.
One critical distinction: most lenders advertise a representative APR, which by FCA rules only needs to be offered to 51% of approved applicants. The rate you actually receive may differ. Oakbrook Finance provides a guaranteed personalised APR at the eligibility stage before you commit to anything so you can make an accurate comparison against your existing debts.
A worked example: consolidating £8,000 across four accounts
The following scenario is based on typical UK household debt patterns reported by StepChange and the Money and Pensions Service.
Current debts:
Debt | Balance | APR | Est. monthly interest |
Credit card 1 | £3,000 | 24.9% | £62 |
Credit card 2 | £2,500 | 29.9% | £62 |
Store card | £1,500 | 28.9% | £36 |
Overdraft | £1,000 | 39.9% | £33 |
Total | £8,000 | Blended ~29% | ~£193/month in interest |
At 3% minimum payments, over £190 of the monthly outgoing services interest alone. Balances reduce very slowly and at this pace, clearing everything could take over a decade.
Consolidation comparison (illustrative):
Separate debts | Consolidation loan at 24.9% APR / 48 months | |
Monthly payment | £230£250 (combined) | £217 (single, fixed) |
Total interest paid | ~£3,200 | ~£2,400 |
Total repayable | ~£11,200 | ~£10,400 |
Estimated saving | ~£800 over 4 years |
Note: These figures are illustrative only and based on assumed minimum payment patterns. Typical savings vary significantly results depend entirely on individual circumstances including your specific balances, current APRs, the rate you are offered, and whether you continue borrowing after consolidating. A longer loan term may reduce monthly payments but increase total interest paid. Always compare the total amount repayable, not just the monthly figure.
Representative example: Borrowing £10,000 over 48 months at 24.9% APR representative and interest rate 24.9% p.a. (fixed). Monthly repayments of £317.64. Total amount payable: £15,246.76. Rates from 19.9% APR to 34.9% APR. Loan terms 1260 months.
Four factors that determine your personal saving
1. Your existing interest rates. The higher your current APRs, the greater the potential saving. If your debts are already lowrate or within a 0% promotional period, consolidation at any positive rate will cost more, not less.
2. The APR you are offered. This depends on your credit history, income, and how much you want to borrow. If the rate offered is similar to or higher than what you are currently paying, consolidation delivers no financial benefit.
3. The loan term you choose. A shorter term costs less in total interest but requires a higher monthly payment. A longer term lowers the monthly figure but increases total interest paid even at a lower rate. The right balance depends on your monthly budget and how quickly you want to be debtfree.
4. Whether you use freedup credit after consolidating. This is the most common reason consolidation fails. If you clear your credit cards and then run balances back up, you will have both the loan repayments and new card debt. Consolidation only improves your position if the cleared accounts stay clear.
When consolidation does not save money
Being realistic about this matters. Consolidation will not save you money if:
- Your debts are already lowinterest or within a 0% promotional period
- You are offered a rate similar to or higher than your current average APR
- You extend the repayment term significantly lower monthly payments over a longer period can mean paying more in total interest despite a lower rate
- You continue borrowing on cleared accounts after consolidating

How to estimate your own potential saving
You do not need to apply to find out where you stand. Follow these steps:
- List every debt with its balance, APR, and current monthly payment
- Add up your total monthly payments this is your baseline to compare against
- Check your eligibility with Oakbrook's soft search returns your guaranteed personalised APR with no credit score impact
- Compare the offered monthly repayment against your current combined payments
- Compare total repayable figures the consolidation loan total versus what you would pay continuing as you are
Always compare the total amount repayable not just the monthly payment. The monthly figure alone does not tell you whether consolidation genuinely saves you money.

The benefits beyond the financial saving
For many borrowers, the simplification matters as much as the saving:
- One payment date instead of several significantly less risk of accidentally missing a creditor
- A fixed end date unlike credit card minimum payments, a consolidation loan tells you exactly when you will be debtfree
- Predictable monthly outgoings a fixed repayment makes budgeting straightforward
- Potential credit score improvement clearing high credit card balances reduces your credit utilisation ratio, which is one of the factors credit reference agencies use to calculate your score. Consistent on time repayments strengthen your payment history over time. These are not guaranteed outcomes, but they are common ones for borrowers who manage the loan responsibly.

It depends on the rate you are offered. If you can access a consolidation loan meaningfully below 20%, the saving is real. If the rate is similar to what you already pay, the financial benefit is limited though simplification and a fixed end date may still be valuable.

Applying triggers a hard credit search, which may cause a small temporary dip typically five to ten points. Over time, consistent on time repayments and reduced credit card utilisation generally improve your score. These outcomes depend on how you manage the loan after consolidating.
