FX.co ★ UK Car Registration Growth Slows to 6.6% in March on Annual Comparison

Year-over-year growth in car registrations in the United Kingdom eased in March, with the indicator slipping to 6.6% from a previously reported 7.2%. Both the current and previous readings relate to March 2026, highlighting a moderation in the annual pace of expansion as updated data became available.

The figures, updated on 07 April 2026, compare changes in car registrations for March 2026 against March a year earlier. The earlier 7.2% reading reflected the prior estimate of this year-over-year change, while the latest 6.6% result indicates that the expansion in registrations, though still solid, was slightly weaker than initially assessed.

The year-over-year comparison framework used here means both the actual and previous indicators measure how March 2026 registrations stack up against the same month of the prior year, underscoring a still-growing but marginally cooling UK auto market.
