Experian launched an enhanced version of Experian Boost in the UK on 9 November 2026, using open banking to show consumers how rent, buy now pay later commitments, household bills and account conduct may look to a lender, with a full roll-out by the end of November. Fintechbits reported that the FCA started regulating buy now pay later on 15 July 2026, four months before Experian Boost began showing users how lenders may read their BNPL commitments.

What the Experian Boost Fine Print Says

The headline claim is that Experian Boost users could cut borrowing costs by up to 22%, saving an average of 340 pounds a year in interest. The notes to editors show the basis: one lender with three brands (Lendable, Asda and Post Office), loans only, over a three-month pilot from July to October 2026, with the saving modelled on a 10,000 pound, 48-month personal loan at 24.5% against 19.2% APR. That is a reasonable test, but it is not a market-wide result.

The rent change is the more durable one. Tenants can add rental payments directly to their credit report for the first time through the tool, and Experian says 71% of 113,259 existing Boost users run through the new version in July 2026 saw a score uplift. Credit card spending data is due in 2027. Fintechbits has also covered Experian’s partnership with Vanquis, announced the same day.

For lenders, this is useful. Affordability rules push them to look past the credit file at real spending, and a consumer who has already connected a current account through Experian Boost gives them that picture in a standard format. For consumers the trade is data for a possibly better score. Experian says every user gets free, personalised guidance on improving eligibility, and that the tool organises account data into categories including rent, household bills, BNPL activity, short-term borrowing and payment issues. The payment issues category cuts both ways: a connected account can show lenders missed payments as easily as good habits.
