Borrowing a car? Insure the days, not the year
Temporary car insurance covers you in someone else's car for hours, days or weeks, in your own name. For a short loan it's often cheaper than a named driver. For regular use, it usually isn't.
Updated 6 October 2026 · Figures sourced and linkedGet a per-day temporary quote and ask the owner's insurer what adding you would cost. Enter both and the days you need: we show which is cheaper and the break-even point.
