Credit Scores Explained: What UK Lenders Actually Look For in 2026
Most people obsess over the three-digit number their Experian or ClearScore app shows them. Here’s the uncomfortable truth: no UK mortgage lender looks at that number. They look at your underlying credit file, and they apply their own scoring model to it. Here’s what actually moves the needle in 2026. The Three Bureaux and Why They Differ There are three credit reference agencies in the UK: Experian, Equifax and TransUnion. Different lenders use different bureaux. Your file at one may be cleaner than at another simply because not every creditor reports to every bureau. The ‘score’ each displays is their own marketing number- useful as a trend indicator, meaningless to mortgage lenders. What Lenders Actually Look At Lenders look at: (a) whether you’ve had any recent adverse events- missed payments, defaults, CCJs, IVAs, bankruptcies; (b) how much of your available credit you’re currently using (utilisation); (c) how many hard credit searches have landed recently; (d) whether you’re on the electoral roll at your current address; (e) the age of your accounts- older is better; (f) the stability of your addresses and employers. The three-digit score summarises these; the underlying data is what’s scored. Electoral Roll- The Quietest Secret If you’re not on the electoral roll at your current address, get on it today. It’s free, it takes two minutes, and it’s one of the single biggest positive signals to a lender. Many marginal applications tip from ‘refer’ to ‘accept’ purely because the applicant’s electoral roll status is current. Credit Utilisation
