A debt consolidation loan replaces several existing debts with one new loan.
The idea is straightforward. You take out a single loan, use it to pay off credit cards, overdrafts and other borrowing, and then repay one lender each month instead of several. On paper it looks tidier. In practice the outcome depends on the new interest rate, the length of the term, whether the loan is secured, and whether the accounts you clear stay closed.
This guide explains what a consolidation loan actually is, when it can genuinely help, when it can quietly make the situation worse, and what the FCA rules on representative APR and affordability really say. It is grounded in the FCA Consumer Credit sourcebook (CONC 5 on creditworthiness and CONC 3 on financial promotions), ICO credit guidance and the FCA mortgage rules that now cover second charge loans.
This is general information about how consolidation loans work in the UK. It is not personal financial advice or regulated debt advice.
Quick answer
A debt consolidation loan is a new borrowing product, not a debt solution. It can help when the new rate is clearly lower, the term is not stretched over many years, and the accounts being cleared are actually closed. It can make things worse when the rate is higher than the advertised figure, the term is very long, or the loan is secured on your home.
Under FCA rules, only 51% of accepted applicants have to be offered the advertised representative APR. The rest can legally be quoted more. Check the personal quote against the headline figure, and use the TRDG Budget Planner to test the monthly payment against your real budget before you sign anything.
Before you accept any consolidation loan offer, put the wider picture in front of yourself. If you are not sure whether your monthly income covers the new payment on top of everything else, use the TRDG Budget Planner. The aim is to understand what is being offered before you sign, not to move quickly because the monthly payment looks lower.
What a debt consolidation loan actually is
A debt consolidation loan is a single new loan taken out to pay off several existing debts. The lender pays out the loan amount, you (or in some cases the lender directly) use that money to clear the older accounts, and you are then left owing one monthly payment to one lender instead of several.
Some consolidation loans are marketed as such. Many are just standard personal loans that people happen to use for that purpose. The rules and risks are the same.
Unsecured consolidation loans
An unsecured loan is not tied to any specific asset. If you fall behind, the lender can chase you for the money in the normal way, and eventually take county court action, but they cannot force the sale of your home to recover it just because the loan is in your name.
Secured consolidation loans (second charge)
A secured consolidation loan is a second charge on your home. The lender registers a charge on the property behind your existing mortgage. If you fall behind, they can take possession action against your home to recover the money.
Since 21 March 2016, second charge mortgages have been regulated by the FCA under the Mortgages and Home Finance Conduct of Business sourcebook (MCOB), not as consumer credit under CONC. That change was set out in the FCA's feedback statement for second charge lenders, and the possession process is now governed by MCOB 13. In March 2026 the FCA published a follow up good and poor practice review of second charge outcomes, and continued to press lenders on affordability and vulnerable customer treatment.
When a consolidation loan can work
A consolidation loan is not a bad idea in every situation. There are cases where the numbers do work, and where a single, cheaper payment is genuinely easier to manage.
The new rate is clearly lower
If the interest rate on the new loan is meaningfully lower than the blended rate you are paying on credit cards, store cards and overdrafts, and the personal quote you receive matches the advertised representative APR, the total cost of credit can come down.
The term is not stretched too far
A shorter term means a slightly higher monthly payment, but far less interest paid overall. A five year unsecured loan at a reasonable rate can cost less in total than the same balance carried on cards for a decade.
The accounts you clear stay closed
The most common reason consolidation goes wrong is that the old accounts stay open and get used again. If credit cards are physically closed and the limits removed once cleared, the debt has actually been resolved. If they stay open, the balance often creeps back on top of the new loan.
The spending pattern has changed
Consolidation solves the payment mechanics, not the pattern. If the reason the original debts built up has been addressed, a single lower payment can genuinely release pressure. If nothing has changed, the same pattern will fill the cards again while the loan runs alongside it.
When a consolidation loan makes things worse
The same product can quietly make the situation worse when the numbers or the structure do not stack up.
The rate you are offered is higher than the advert
The advertised representative APR is a marketing figure, not a personal quote. The FCA rules on this are covered in the next section, but the short version is that a large minority of accepted applicants are offered a rate above the headline number.
The term is very long
A ten year consolidation loan at a modest rate can still cost more in total interest than three years of credit card debt at a higher rate, simply because interest is charged for so much longer. Always compare the total cost of credit, not just the monthly payment.
The loan is secured on your home
A second charge loan can look attractive because the rate is often lower than an unsecured personal loan. What you are paying for that lower rate is your home standing behind the debt. If income drops, the consequence is not a black mark on a credit file, it is a possession claim under MCOB 13.
The old accounts stay open and get used again
If the credit cards cleared by the loan stay open, and the balances slowly rebuild, you end up with the loan and the cards. That is worse than the starting position, not better.
The application itself is not the right route
Under FCA CONC 5.2A, a lender must carry out a creditworthiness assessment before offering credit. That includes an affordability assessment. The rule is not just whether you are likely to repay in the sense the lender gets its money back, but whether you can repay in a sustainable manner without significant adverse consequences for you. Being declined for a consolidation loan is often a signal from the lender's own affordability check that the borrowing would not be sustainable, and that is worth taking seriously.
Representative APR: the 51% rule most consumers do not know
This is the part of a consolidation loan advert that catches people out most often. It is not hidden, but it is not obvious either.
When a lender advertises a loan with a headline rate, that figure has a specific legal meaning. Under FCA CONC 3.5 on financial promotions, the representative APR is defined as the rate at or below which the lender reasonably expects to provide credit to at least 51% of the people who enter into agreements as a result of the advertisement.
In plain English, the headline rate is not a promise:
- It is not 51% of applicants. It is 51% of successful applicants.
- It is not everyone. Just under half of the people who get approved can be offered a higher rate.
- The lender chooses your rate. They set it after they see your credit file, not before.
If the rate you are offered is materially higher than the advertised one, that is not a rule breach on its own, but it is a reason to pause before signing.
An 8.9% representative APR advert is not a promise of 8.9%. It is a promise that at least half of accepted applicants will be offered 8.9% or lower. The other half can legally be offered a materially higher rate.
The Real Debt GuySo a lender can honestly and lawfully advertise an eye catching rate, accept your application, and quote you a rate that is meaningfully higher, as long as they still meet the 51% threshold across everyone they accept. Nothing about that is a scandal. It is simply the rule. Most consumers do not know it exists.
Why this matters for consolidation loans
Consolidation loans are almost always shopped by APR. If the rate that lands in front of you when the personal quote arrives is not the rate that pulled you in, the whole business case for consolidating can change. The monthly saving disappears, the total cost of credit rises, and the loan may cost more than the debts it was meant to replace.
Secured consolidation loans and your home
Secured loans are worth their own section because the risks are different in kind, not just degree.
A secured consolidation loan is a second charge on your property. If your first mortgage lender ever needed to enforce their charge, the second charge lender would rank behind them, but their charge is still real. If you miss payments on the second charge loan, that lender can take independent possession action against your home under MCOB 13.
Two points worth understanding:
Affordability rules are stricter, but the loan is bigger
Under MCOB 11, a second charge lender must assess whether you can afford the repayments considering the first mortgage and reasonable future interest rate rises. That is a stricter test than for unsecured credit. But because the loan is secured on your home, it is often for a much larger amount and over a much longer term, so a small change in circumstances can matter more.
The FCA is actively supervising this market
In March 2026 the FCA published its good and poor practice review of second charge mortgages, which looked at whether intermediaries and lenders were delivering fair outcomes under the Consumer Duty. It sets out clear expectations on affordability, vulnerable customer support and post sale communication. That is a signal that the FCA views this market as one where consumer harm can happen, not a routine borrowing product.
Before agreeing a second charge consolidation loan, it is worth being honest about the answer to one question. If the payments become difficult in year three or year seven, what is the plan? On an unsecured debt the answer can be a repayment arrangement, a partial settlement, or eventual write off. On a secured debt the answer sits closer to your front door.
What a consolidation loan does to your credit file
A consolidation loan interacts with your credit file in several ways at once.
The application itself
Applying for a loan usually creates a hard search on your file. Multiple hard searches in a short period can lower your score temporarily. Some lenders offer soft search quotes first, and it is worth using those before committing to a formal application.
Once the loan is opened
The new loan appears on your file. If used to clear the old accounts, those should show as settled. Your total debt to credit ratio may improve, especially if the old cards are closed. If the cards are left open with zero balances, your available credit rises, which affects future lending decisions.
Missed payments on the new loan
Any missed payments on the consolidation loan create fresh negative markers. If the loan defaults, that default sits on your credit file for six years from the date it is registered. This is a longstanding principle set out in ICO guidance and echoed in every Financial Ombudsman decision on the topic.
Older accounts
If any of the old accounts you consolidated had already defaulted before you took the new loan, that default remains on your credit file for six years from its original date. Consolidation does not remove existing default markers. It only settles the balance.
The three UK credit reference agencies, Experian, Equifax and TransUnion, each maintain their own record. It is worth checking all three before applying, because a lender may use any of them.
What to check before you sign
Before you accept a consolidation loan offer, work through this list:
- The APR on the personal quote, not the advertised representative APR.
- The total amount payable over the full term, not just the monthly figure.
- Whether the loan is secured on your home, and if so, what the possession process would look like if you fell behind.
- Any arrangement fees, broker fees, early repayment charges or insurance costs added into the loan.
- Whether the loan amount clears every account you intended to clear, or leaves a stub balance somewhere.
- Whether the old accounts will be closed once cleared, and what confirmation you will get.
- Whether the new monthly payment fits your real budget, priority bills first.
- What the plan is if income drops or a cost rises during the loan term.
If any of those points is unclear, do not sign on the assumption it will be explained later. The paperwork before you sign is what governs the account afterwards.
If a consolidation loan is not the answer
Being declined for a consolidation loan is not a defeat. In many cases it is the affordability check doing its job. There are alternatives worth understanding.
Talk to each creditor about affordability
Under FCA rules in CONC 7.3, firms must treat customers in default or arrears with forbearance and due consideration. That includes looking at what is genuinely affordable rather than demanding the contractual amount. A structured affordability based arrangement, supported by a budget, is a legitimate route.
Alternative routes if a loan is not right
If a consolidation loan is not affordable or you are declined, an FCA authorised debt information provider of your choice can look at whether a formal debt solution fits your circumstances better than more borrowing.
Formal debt solutions
If the situation is more serious than the monthly figure suggests, a formal debt solution may fit better than a new loan. The four main options in England and Wales are:
- Debt Management Plan (DMP): an informal arrangement, usually set up through a free provider, where reduced monthly payments are made to each creditor based on what you can afford. Not legally binding on either side.
- Debt Relief Order (DRO): a formal insolvency route for people with low income, low assets and total debts under the statutory limit. Debts are written off after 12 months if circumstances have not improved.
- Individual Voluntary Arrangement (IVA): a legally binding agreement, arranged through an Insolvency Practitioner, to pay a fixed amount for a set period (often 5 or 6 years). Any remaining unsecured debt is written off at the end.
- Bankruptcy: a court-based insolvency route that clears most unsecured debts, usually after 12 months. Has consequences for assets, credit file and some professions.
Every formal solution has its own consequences. Speak to a qualified debt adviser or an FCA authorised organisation before starting one.
FAQs
Is a debt consolidation loan a good idea?
Sometimes yes, often no. It can help if the new interest rate is clearly lower, the term is not unreasonably long and the accounts being cleared are actually closed. It can make things worse if the rate is higher than you think, the term is stretched over many years, the loan is secured on your home, or nothing changes in the spending pattern that produced the debts.
Does a debt consolidation loan hurt your credit file?
A new loan means a hard search on your credit file. Once accepted, the new loan appears and the old accounts should show as settled. Missed payments on the consolidation loan itself would create fresh negative markers. Any default already recorded on the older accounts stays on your credit file for six years from the default date under ICO guidance.
What does representative APR actually mean?
Under FCA CONC 3.5, a lender advertising a representative APR must offer that rate or lower to at least 51% of the people it accepts as a result of the advertisement. The other 49% of accepted applicants can legally be offered a higher rate. The headline APR is a marketing floor for a bare majority, not a personal quote.
Can I be turned down for a consolidation loan?
Yes. Under FCA CONC 5.2A, a lender must carry out a creditworthiness assessment that considers whether repayments can be made in a sustainable manner. If the lender concludes the borrowing is not affordable for you, or your credit file already shows stress, the application can be declined or offered at a higher rate than the advertised representative APR.
Is a secured consolidation loan safer?
Not for you. It is safer for the lender. A secured loan uses your home as collateral. Since 21 March 2016, second charge mortgages have been regulated by the FCA under MCOB rather than as consumer credit, and missed payments can lead to possession action under MCOB 13. Turning unsecured debts into secured debts changes the consequence of falling behind.
What happens to the old accounts?
The consolidation loan pays them off, but the accounts stay open unless you close them. If they are left open, you can build up new balances on top of the loan, and end up with more debt than you started with. Ask for the accounts to be closed once cleared, and get confirmation in writing.
How long should the term be?
A shorter term means a higher monthly payment but less interest paid in total. A longer term is easier month to month, but the interest paid over the life of the loan can be far greater than the interest that would have accrued on the original debts. Compare total cost of credit, not just the monthly figure.
What is the alternative if I cannot get a consolidation loan?
You have more options than the loan. You can speak to each creditor about affordability based repayments under CONC 7.3. You can approach an FCA authorised debt information provider of your choice. If the situation is more serious, a formal debt solution may fit better than more borrowing: a Debt Management Plan, a Debt Relief Order, an Individual Voluntary Arrangement or bankruptcy. Being declined for consolidation is a signal, not a defeat.
Where can I check if I can afford the payments?
Use the TRDG Budget Planner to work out your income, priority bills and essential living costs before agreeing to any consolidation loan. Any new monthly payment must sit on top of a budget that already covers rent or mortgage, council tax, utilities, food and transport.
