How to check and improve your credit score

Confused or concerned about your credit rating (and still not completely sure what it is, if you’re being honest)? We’ve got everything you need to know plus tips to improve your score!

There tends to be a whole lot of confusion involved when it comes to credit scores (a.k.a. credit ratings) – and to be honest, that’s really not surprising.

What we do know, however, is that having a good credit score is really important, particularly if you ever want to apply for anything like a mortgage or a loan.

These things might seem a bit far into the future to be thinking about now, but the key to building a great credit score is to get started on improving it nice and early!

We’re here to fill you in on exactly why your credit rating matters so much, and how to get working on improving it.

What is a credit score and what affects it?

Essentially, a credit score is a kind of grading system used by banks and lenders to work out how much money you should be given when you apply for financial products like credit cards, overdrafts or a mortgage (or whether you should qualify for these ‘products’ at all).

In some instances, a poor credit score could totally disqualify you from being eligible to borrow money, so it’s definitely worth being aware of what it is and how it’s calculated.

Your credit score is determined by a whole range of factors, most notably including the following:

But remember, these are just a handful of the determining factors – we’ll go into more detail on how credit scores are calculated later on.

How important is your credit score?

As a student, it’s unlikely you’ll have had much chance to make or break your credit rating – particularly considering that the length of your credit history also plays a role in determining your score, and only once you become an adult will you have the opportunity to build it.

But while your credit score is likely still in its infancy, and you probably won’t be buying a house or taking out substantial loans for a few years now, there’s nothing wrong with trying to improve it early doors – especially as a good credit score will help you apply for a credit card and student overdraft.

Why do you need a credit score?

Your credit score is one of the most important things that banks will consider when you apply for a mortgage, and it will determine how generous they’re likely to be with the repayment terms. As such, anything you can do now to improve your score is worth doing.

However, as valuable as a good credit score is, it’s not the only factor that a lender will consider when you apply for credit. Among other things, they’ll also look at the affordability of the debt – in other words, can somebody on your salary, and with the other financial commitments you have, afford to make the monthly payments required?

And despite what you might’ve been told in the past, the idea that there’s some sort of credit score ‘blacklist’ that prevents people from taking out loans isn’t true, so don’t worry! Just remember that if your credit score is low, it’ll make being accepted for financial products more unlikely.

Oh, and if you think that you can try to minimise your credit history in an effort to avoid a bad credit score, think again. Having no credit history is just as bad as having a poor credit history, as lenders are keen to see evidence of you having successfully and reliably repaid credit in the past. In other words, you can’t game the system. Sorry.

What are credit scores used for?

People often assume that your credit rating only comes into play when you’re applying for a mortgage or loan, but this isn’t the case.

Here’s a list of the main financial products and services for which a good credit score should improve the chances of your application being accepted (and with better rates):

These are all forms of credit, and if your credit score is poor, your application for the best interest rates may be unsuccessful – and you could be rejected altogether.

Are credit ratings reliable?

Annoyingly, your credit score isn’t a set, indisputable number. Instead, it will vary depending on the agency being asked to calculate it.

We’ll run through the three main companies later on, but it’s important to note that they all use different scales and will all probably give you slightly different ratings. This is largely down to the fact that a credit score is the result of a complex mathematical calculation, and each organisation has its own way of formulating it.

So, as your credit score can differ depending on who’s providing it, it’s worth tracking your rating through multiple companies rather than just the one.

To exemplify, one of the members of the Save the Student team used two credit checkers to find out their score. The first, from ClearScore (which uses Equifax’s data), was 300/700, while the second, from Experian, was a whopping 969/999. A pretty substantial difference, we’re sure you’ll agree.

While it’s fairly uncommon to have such a disparity between two credit scores (in this case, it could even suggest that one of the reports has made a mistake!), it highlights how a single credit score can be unreliable.

How are credit scores calculated?

Nobody (outside of the credit agencies, of course) knows the exact criteria used to determine a credit rating, and different credit companies use a variety of factors when grading you. This is why it’s best to check with all three (see the companies below) in order to give yourself an accurate figure.

Nonetheless, we are able to say which big factors are definitely taken into consideration, and which aren’t.

How to check your credit rating for free

If you’re concerned about your credit score – or are even just a bit curious to see what yours looks like – then it’s possible to check your records with all three major credit agencies for free. You can also pay a fee (be it monthly or one-off) to take a closer look at your report.

Remember that each credit company will grade your score differently, so it’s best to check all three to get a good overview of your situation.

UK credit agencies

  1. Experian


    Experian is one of the leading credit referencing agencies, and your credit score can now be accessed for free here.

    For a deep-dive into your full report, including real-time tracking and notifications when changes happen, Experian offers its CreditExpert service for £14.99 a month.

    However, new CreditExpert users are eligible for a free 30 day trial (just make sure you cancel before the trial expires, otherwise you will be charged).

  2. Equifax

    The best way to check your Equifax score is to apply through a company called ClearScore.

    The two companies are not directly linked to one another, but ClearScore uses Equifax’s data to present your credit score for free. ClearScore will also send you deals on credit cards and other financial products, but you’re better off just ignoring them.

    Otherwise, you can sign up to a free 30 day trial directly with Equifax. Just note that an Equifax subscription will cost £7.95 a month after the free trial finishes, and unless you remember to cancel, you will be charged.

  3. TransUnion (was Callcredit)

    transunion logo

    TransUnion is rarely used by banks and other lenders, so the whole “don’t just check one credit score” mantra is doubly important here.

    You can check your score for free through Credit Karma (formerly Noddle) or TotallyMoney so it’s worth giving this one a bash to see how your score stands.

    Be aware that both services will advertise credit cards, loans and other financial products in an effort to get you to apply. There’s no obligation to do so, and you’re always better off doing your own research on the best options for you!

How to improve your credit rating

Here are our top tips for improving your credit score:

  1. Get on the electoral roll

    Registering to vote is probably the single easiest thing you can do to boost your credit rating, as if you’re not on the electoral roll, you’ll find it a lot harder to make a successful application for credit.

    A lot of students fall foul on this one because after moving away from home, registering at a new address can seem like a hassle.

    But it’s actually super easy to register online (literally about two minutes of your time), and you’ll struggle to find an easier way to improve your credit score. Side note: you can also make money from elections too…

    You’ll find everything you need to know about how to register for the electoral roll on the Your Vote Matters website.

  2. Make sure the details are correct

    If you don’t agree with something in any of your credit reports – or you’ve noticed any errors (this can happen!) – then you’ll need to make sure something’s done about it.

    You can fix this by calling up the credit company themselves and asking if they’ll look into the errors. They may also require you to contact the company that has given them the incorrect data (e.g. your mobile phone company or your bank) to amend it.

  3. Pay all your bills on time

    The most simple way to improve your credit score is to make sure that you pay all of your bills on time.

    This includes utility bills, mobile phone contracts, rent and any form of loan repayments (except Student Loans, of course!). If you’re good at paying your rent on time, you can also use this to score points on your credit report by setting up an account with Credit Ladder (more on this in the next point).

    Just be cautious about having your name on all the bills if you’re in a shared household. In this scenario, if just one person can’t afford to pay up and the payment is missed, everyone’s credit score could be affected.

  4. Use Credit Ladder to record your rent payments

    Since March 2016, it’s now possible to arrange for your rent payments to be shown in your credit report. Inventively called ‘The Rental Scheme,’ this is a great option for anyone who’s good at paying their landlord in time and looking for ways to beef up their credit score.

    All you need to do it sign up to a third party website called the Credit Ladder. Credit Ladder then verify your rent payments when they go to your landlord or letting agent.

    Every time a payment is made they record how punctual you are with the payment and whether you paid the right amount, and they then store this data to be picked up in your credit report. Nice.

  5. Get a credit card and use it wisely

    As long as you don’t let things get out of hand, taking out a credit card and simply using it will help to boost your credit score.

    It makes sense, really. Your credit rating is used by lenders to see how reliable you are at making repayments, and with a credit card you’ll be essentially ‘given’ money to spend by the bank each month. It’s then up to you to repay it on time.

    We’d recommend only using it to spend as much money as you would if it were your own money (which, ultimately, it will eventually be), and always paying off your credit card in full each month (set up a Direct Debit to do this for you). Late payments will damage your credit score, and unless you repay in full each month, you’ll have to pay interest too.

    One technique for using a credit card responsibly is to assign a specific purpose to it, like paying for a holiday. If you only ever use it to pay for purchases related to your holiday, you should find it easier to keep track of how much you’ve spent on the credit card, and how much needs to be repaid.

    If you’re not keen to go down the credit card route (or you’re not in a position to get your hands on one) there are some prepaid credit cards that have features specifically designed to help build your credit score.

  6. Space out applications for credit products

    Every time you apply for a credit product, like a mobile phone contract or a new credit card, it leaves a ‘footprint’ on your credit report. This is largely because banks want to know if you’re currently making a lot of credit applications, as this could indicate you’re in a poor financial situation and are therefore less likely to be able to pay the money back.

    The key is to make sure you spread out your applications as much as possible, and only apply if you really need to. If you’re denied credit at any point, wait at least 30 days before reapplying.

Remember that your score won’t shoot up overnight, but just being aware of the risks and knowing the steps you can take to give your rating that boost it needs will work wonders in the long run.

How to avoid a bad credit rating

Finally – there are a few small things to be aware of that might be damaging your credit score without you even realising!

  1. Never use your credit card to withdraw cash at an ATM – Not only are interest rates on this completely ludicrous, but it’ll show up on your credit report, too. Withdrawing cash using a credit card gives the impression you’ve had to resort to emergency measures, spending cash that isn’t yours as a consequence of bad budgeting.
  2. Never take out a payday loan – Of course, we already know how terrible payday loans are for your long-term bank balance. But just having them appear in your credit report looks terrible to lenders, and taking out a payday loan is arguably one of the worst things you can do for your credit score.
  3. Never pay out for what’s advertised as a ‘credit repair service’ – Essentially, there’s nothing that these companies can do that will help you (except advise you on all of the above points, which we’ve just given you for free!). Don’t waste your money on these guys.
  4. Don’t hold on to any old store cards This is especially true if you’re not still using them! We’re not fans of store cards anyway, but if you’re seen to have heaps of credit sitting around and not being used, this can be damaging too.

Hopefully, we’ve shed at least a tiny bit of light on the complex mystery otherwise known as the world of credit scoring! We know this stuff can be a bit of a headache, but you’ll get there!

The trick is just to try and show the banks that you know to look after your bills, and the banks will look after you (in theory).
