Credit, Credit Scores & Borrowing
What a credit score is, how it's built or damaged, and why it shapes future financial decisions.
Your credit score is a number that lenders use to assess how likely you are to repay money you borrow. It influences whether you're accepted for a mortgage, a personal loan, a credit card, or even a mobile phone contract, and often affects the interest rate you're offered if you are accepted.
Many people either don't know their score, don't understand how it's calculated, or assume it's something that just exists and can't be influenced. None of those positions is particularly useful. Your credit score is something you can understand, monitor, and actively improve.
How credit scores work in the UK
In the UK, the three main credit reference agencies are Experian, Equifax, and TransUnion. Each holds data about your financial history and generates a score based on it. Lenders may use one, two, or all three when assessing an application. The scores aren't identical across agencies, but the underlying factors that influence them are broadly the same.
You can check your score for free with each agency. Checking your own score does not affect it.
What affects your score
Borrowing: a framework for decisions
Not all borrowing is the same. A mortgage taken to buy an asset that may appreciate over time is a fundamentally different decision to a high-interest personal loan taken to cover a spending shortfall. Understanding the type of debt matters before making any borrowing decision.
The cost of borrowing is the interest rate multiplied by the time you hold the debt. A £5,000 loan at 12% APR held for five years costs significantly more than the headline rate suggests. Always calculate the total repayable, not just the monthly payment.
When assessing any borrowing decision, three questions are worth asking. Can you genuinely afford the repayments if your circumstances change? Do you understand the total cost over the full term? And is this the most cost-effective way to access the money you need?
Improving a poor credit score
A poor credit score is not permanent. It reflects the past, not the future. The most effective ways to improve it over time are: register on the electoral roll, pay all existing commitments on time without exception, reduce credit card balances below 30% of the limit, avoid applying for new credit frequently, and allow time for older negative marks to age off the file.
There are no shortcuts that work reliably. Services that promise to repair your credit quickly are rarely worth the cost. Consistent behaviour over 12 to 24 months is what actually moves the number.
Credit and borrowing decisions are often driven by something other than a rational cost calculation. The Conscious Currency explores the emotional relationship with debt: what it represents, and what drives people towards it or away from it.
