Understanding Credit Scores and How They Affect Remortgaging
Your credit score is a numerical representation of your creditworthiness, calculated by credit reference agencies based on the information in your credit file. In the UK, the three main credit reference agencies each have their own scoring systems, which means your score can vary depending on which agency you check with.
How credit scoring works in the UK
Each of the three main agencies uses a different scale:
- Experian — Scores range from 0 to 999. A score of 721-880 is considered fair, and anything below 720 is considered poor.
- Equifax — Scores range from 0 to 1000. A score of 380-419 is considered fair, and anything below 379 is considered poor.
- TransUnion — Scores range from 0 to 710. A score of 566-603 is considered fair, and anything below 565 is considered poor.
It is important to understand that lenders do not necessarily use these exact scores when making decisions. Most lenders have their own internal scoring systems that take data from your credit file and combine it with other factors such as your income, employment status, existing commitments, and the amount of equity in your property.
What causes a low credit score
Many factors can contribute to a low credit score, including:
- Late or missed payments — Even a single missed payment can reduce your score, and the impact increases with more missed payments.
- High credit utilisation — Using a large proportion of your available credit (for example, having credit cards close to their limits) negatively affects your score.
- County court judgements and defaults — These serious adverse credit markers have a significant negative impact on your score.
- Too many credit applications — Multiple hard searches in a short period can lower your score, as they suggest you may be struggling financially.
- Lack of credit history — Paradoxically, having no credit history can result in a low score because there is insufficient data to assess you positively.
- Not being on the electoral roll — This is a surprisingly common cause of lower scores that is easy to fix.
- Financial associations — Being financially linked to someone with poor credit can affect your own score.
Understanding what is driving your low score is the first step towards improving it and increasing your remortgage options.
Can You Remortgage With a Low Credit Score?
Yes, you can remortgage with a low credit score. The UK mortgage market includes a wide spectrum of lenders, from those who require excellent credit scores to those who specialise in helping borrowers with imperfect credit. The key is finding the right lender for your circumstances.
High street lenders
Most high street banks and building societies have minimum credit score requirements, and applications that fall below their thresholds are typically automatically declined. However, the exact thresholds vary between lenders, and some are more lenient than others. Your score might be too low for one bank but perfectly acceptable to another.
Specialist lenders
The specialist lending market has grown considerably in the UK. These lenders focus on serving borrowers who do not fit the rigid criteria of high street banks. Many specialist lenders use manual underwriting, which means a person reviews your application rather than an algorithm. This allows them to consider the context behind your credit score and make more nuanced decisions.
Building societies
Many building societies, particularly smaller regional ones, take a more personal approach to mortgage lending. They may be more willing to look beyond your credit score and consider your broader financial situation, including how you have managed your existing mortgage.
Your existing lender
Do not overlook the option of a product transfer with your current lender. Because they already hold your mortgage, they have first-hand evidence of your payment behaviour. Many lenders will offer existing customers a new product without requiring a full credit reassessment, which can be advantageous if your score has dropped since you took out your original mortgage.
The interest rates available to you with a low credit score will generally be higher than those offered to borrowers with excellent credit. However, they can still represent a significant saving compared to your lender's standard variable rate, which is often substantially more expensive than any fixed or tracker product.
Practical Steps to Improve Your Credit Score
Improving your credit score before applying to remortgage can expand your options and help you access better rates. While some improvements take time, others can have an almost immediate effect.
Quick wins that can boost your score fast
Some actions can improve your credit score within just a few weeks:
- Register on the electoral roll — If you are not already registered, do this immediately. It is one of the simplest and most effective ways to boost your score.
- Correct errors on your credit report — Check your reports with all three agencies and dispute any inaccuracies. Common errors include addresses you have never lived at, accounts you do not recognise, or incorrect payment statuses.
- Remove outdated financial associations — If you are financially linked to an ex-partner or former flatmate with poor credit, request that the link is removed from your file. The credit reference agencies have processes for this.
- Reduce credit card balances — If your credit cards are close to their limits, paying them down can quickly improve your utilisation ratio and boost your score.
Medium-term improvements (one to six months)
These steps take a little longer but can make a meaningful difference:
- Set up direct debits for all bills — Consistent, on-time payments are one of the biggest positive factors in your credit score. Automating your payments eliminates the risk of accidental missed payments.
- Reduce your overall credit utilisation — Aim to use no more than 25-30% of your available credit across all your credit cards combined. If you have a card with a 1,000 pound limit, try to keep the balance below 300 pounds.
- Avoid new credit applications — Each hard search slightly lowers your score. In the months leading up to your remortgage, avoid applying for any new credit unless absolutely necessary.
- Pay more than the minimum — On any debts, try to pay more than the minimum required payment. This reduces your balances faster and demonstrates to lenders that you can manage your finances well.
Longer-term strategies (six months and beyond)
For more substantial improvements:
- Build a positive payment track record — Six to twelve months of perfect payment behaviour can significantly improve your score and demonstrate to lenders that you have turned a corner financially.
- Close unused credit accounts strategically — While having available credit can be positive, too many open accounts can be viewed negatively. Close any accounts you no longer use, but keep your oldest accounts open as they contribute to the length of your credit history.
- Pay off outstanding debts — Systematically reducing and eliminating your debts will improve both your credit score and your affordability when applying for a remortgage.
Be patient with the process. Credit scores do not change overnight, but consistent positive behaviour will be rewarded over time.
